Description

CROSS-REFERENCE TO RELATED PATENT APPLICATION

This application claims the priority of Chinese Patent Application No. 202423290008.4, filed on Dec. 30, 2024, which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

This application relates to the technical field of accessories, particularly to a magnetic buckle.

BACKGROUND OF THE DISCLOSURE

When it comes to connecting components in various applications such as luggage, clothing, helmets, seat belts, keychains, and other areas requiring connecting accessories, buckles or magnetic buckles are generally used as the connecting accessories. Existing buckles often employ a press-fit or plug-and-play method for engagement. During the unlocking and self-locking processes, existing buckles often require a specific angle to successfully separate or connect the components, making the assembly and disassembly procedures cumbersome and impractical, resulting in a poor user experience and satisfaction. On the other hand, existing magnetic buckles rely on the magnetic attraction between magnetic components to achieve separation and connection among multiple parts. However, during the connection process, they only rely on the magnetic attraction for fixed connection between magnetic components. When subjected to significant external forces, they are prone to slipping or accidental separation between the magnetic components, which may lead to the loss of users' items or even endanger their safety.

SUMMARY OF THE DISCLOSURE

The purpose of this application is to address the defects and shortcomings of the existing technology by providing a magnetic buckle that offers the advantages of flexible and quick self-locking, convenient unlocking, and secure locking.

To achieve this purpose, the technical solution adopted in this application is a magnetic buckle comprising:

• • a first buckle body, with a first groove opened at its lower end;
  • a second buckle body, one end of which is detachably assembled within the first groove;
  • a first magnetic member, provided within the first groove;
  • a second magnetic member, provided on the end of the second buckle body facing the first groove;
  • a buckle member, comprising: a buckle member body rotatably assembled on the first buckle body, a pressing portion provided on the buckle member body and away from the first groove, and a buckle portion provided on the buckle member body and close to the first groove;
  • an elastic reset member, placed between the pressing portion and the first buckle body;
  • when the pressing portion is pressed, the elastic reset member is compressed, and the buckle portion rotates outwardly; the second buckle body is pulled in a direction away from the first buckle body, such that the pull force on the second buckle body exceeds the mutual attractive force between the first magnetic member and the second magnetic member to separate the first buckle body and the second buckle body;
  • when the second buckle body moves in the direction towards the first buckle body, and the second buckle body opens the buckle portion with the magnetic assistance of the first magnetic member and the second magnetic member to cause the buckle portion to rotate outwardly, the second buckle body is placed into the first groove, and the buckle portion resets to buckle the second buckle body under the action of the elastic reset member.

This application further comprises the following settings. Two buckle members are provide.

This application further comprises the following setting: a first guiding slope, which rises upwards from left to right, is provided on the surface of the buckle portion facing the second buckle body; a second guiding slope, which is connected to the top surface of the end of the second buckle body facing the first groove and inclines outwardly, and a third guiding slope, which is connected to one side of the second guiding slope and inclines outwardly, are provided on the side of the end of the second buckle body facing the first groove; the first guiding slope, the second guiding slope, and the third guiding slope cooperate to facilitate the placement of the second buckle body into the first groove.

Further configurations of the present application are shown as below. The buckle member body is rotatably assembled onto the first buckle body via a rotating assembly; the rotating assembly comprises a shaft seat provided on the side of the buckle member body facing the first buckle body, a first installation groove opened on the side of the first buckle body facing the buckle member body and for accommodating the shaft seat, a pivot installation hole opened on the side of the first buckle body facing the buckle member body and communicating with the first installation groove, and a pivot passing through the pivot installation hole and engaging with the shaft seat.

Additional configurations of the present application are shown as below: an outwardly protruding raised portion is provided on the side of the pressing portion facing away from the first buckle body.

Moreover, the present application is further configured such that a second installation groove recessed away from the first buckle body is opened on the side of the pressing portion facing the first buckle body, and a third installation groove recessed away from the pressing portion and corresponding in position to the second installation groove is opened on the side of the first buckle body facing the pressing portion; the second installation groove and the third installation groove cooperate to restrict the elastic restoring member.

Furthermore, the first buckle body is provided with a buckle member installation groove for installing the buckle member.

Additionally, a through hole communicating with the first groove is opened in the buckle member installation groove at a position corresponding to the buckle portion, to allow the buckle portion to extend into the first groove when it resets.

Moreover, a ring-shaped groove engaging with the buckle portion is opened on the peripheral side of one end of the second buckle body facing the first groove.

Additionally, a second groove recessed away from the first groove is opened on one end of the second buckle body facing the first groove, and the second groove is used for installing the second magnetic member.

After adopting the above technical solutions, the beneficial effects of the present application are as follows. In the present application, simply pressing the pressing portion to drive the buckle portion on the other end of the buckle member body to rotate outwardly allows unlocking of the engagement of the buckle portion with the second buckle body. At this point, pulling the second buckle body away from the first buckle body such that the tensile force on the second buckle body is greater than the mutual attractive force between the first magnetic member and the second magnetic member allows separation of the first buckle body and the second buckle body. The overall unlocking process is convenient and quick. After unlocking the engagement of the buckle portion with the second buckle body, there is still a mutual attractive force between the second buckle body and the first buckle body, preventing accidental rotation of the buckle portion and accidental dropping of the second buckle body. When the second buckle body moves towards the first buckle body, and with the assistance of the magnetic attraction between the first magnetic member and the second magnetic member, the second buckle body spreads open the buckle portion to cause the buckle portion to rotate outwardly. The second buckle body is then placed into the first groove, and under the action of the elastic restoring member, the buckle portion resets to engage the second buckle body. The self-locking is flexible, and the first buckle body and the second buckle body can be engaged without requiring a specific angle, with convenient and quick operation. Moreover, after the first buckle body and the second buckle body are engaged, the buckle portion resets to engage the second buckle body, increasing the firmness between the first buckle body and the second buckle body and ensuring the stability of the lock between the two.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

A detailed description of the present application is provided in conjunction with the accompanying drawings.

This specific embodiment is merely an interpretation of the present application and does not limit it. Technical personnel in the field can make modifications without creative contribution to this embodiment after reading this specification as needed, but as long as it falls within the scope of the claims of the present application, it is protected by the patent law.

This embodiment relates to a magnetic buckle. Referring to FIGS. 1-3, it comprises: a first buckle body 100, a second buckle body 200, a first magnetic member 310, a second magnetic member 320, a buckle member 400, and an elastic reset member 500. The first buckle body 100 has a first groove 110 formed at its lower end; one end of the second buckle body 200 is removably assembled into the first groove 110; the first magnetic member 310 is provided within the first groove 110; and the second magnetic member 320 is provided on the end of the second buckle body 200 facing the first groove 110. The first magnetic member 310 and the second magnetic member 320 cooperate to enable the first buckle body 100 and the second buckle body 200 to buckle together under the mutual attractive force between them. The buckle member 400 comprises: a buckle member body 410, a pressing part 420, and a buckle portion 430. The buckle member body 410 is rotatably assembled on the first buckle body 100; the pressing part 420 is provided on the buckle member body 410 and away from one end of the first groove 110; and the buckle portion 430 is provided on the buckle member body 410 and close to one end of the first groove 110. The elastic reset member 500 is placed between the pressing part 420 and the first buckle body 100. When the pressing part 420 is not pressed, one end of the elastic reset member 500 abuts the pressing part 420, and the other end abuts the first buckle body 100. Since both the buckle portion 430 and the pressing part 420 are located on the buckle member body 410, with the pressing part 420 provided on the buckle member body 410 and away from one end of the first groove 110, and the buckle portion 430 provided on the buckle member body 410 and close to one end of the first groove 110, the buckle portion 430 extends into the first groove 110 to buckle the second buckle body 200, thereby locking the first buckle body 100 and the second buckle body 200 together.

Referring to FIGS. 4-6, the operation to unlock the first buckle body 100 and the second buckle body 200 is as follow. The pressing part 420 is pressed to cause the buckle member body 410 to rotate, and the pressing part 420 compresses the elastic reset member 500, placing it in a compressed state. The buckle portion 430, located on the other end of the buckle member 400, rotates outwardly. The user pulls the second buckle body 200 in a direction away from the first buckle body 100, so that the pulling force on the second buckle body 200 is greater than the mutual attractive force between the first magnetic member 310 and the second magnetic member 320, allowing the first buckle body 100 and the second buckle body 200 to separate.

The overall unlocking process is convenient and fast. Simply pressing the pressing part 420 and pulling the second buckle body 200 outwardly completes the separation of the first buckle body 100 and the second buckle body 200, making the operation simple. Moreover, after unlocking the buckle of the buckle portion 430 on the second buckle body 200, there is still a mutual attractive force between the second buckle body 200 and the first buckle body 100, preventing accidental rotation of the buckle portion 430 and accidental dropout of the second buckle body 200.

The operation to lock the first buckle body 100 and the second buckle body 200 is as follows. The user moves the second buckle body 200 towards the first buckle body 100, and the second buckle body 200 spreads open the buckle portion 430 with the magnetic assistance of the first magnetic member 310 and the second magnetic member 320. At this point, the buckle portion 430 rotates outwards, and the elastic reset member 500 is in a compressed state. The second buckle body 200 is placed within the first groove 110. Due to the mutual attractive force between the first magnetic member 310 and the second magnetic member 320, the first buckle body 100 and the second buckle body 200 are engaged. The buckle portion 430 resets to buckle the second buckle body 200 under the action of the elastic reset member 500, further securing the second buckle body 200 with the first buckle body 100.

The self-locking operation is flexible, allowing the second buckle body 200 to be placed into the first groove 110 without requiring a specific angle to engage the first buckle body 100 and the second buckle body 200, which is convenient and swift. After the first buckle body 100 and the second buckle body 200 are engaged, the buckle member 400 resets to buckle the second buckle body 200, further securing the engagement between the first buckle body 100 and the second buckle body 200, and ensuring the robustness of their connection.

It should be noted that both the first magnetic member 310 and the second magnetic member 320 can be magnets, or one can be a magnetic material while the other is a metallic material. It suffices as long as there is a mutual attractive force, including magnetic attraction, between the first magnetic member 310 and the second magnetic member 320. In this embodiment, both the first magnetic member 310 and the second magnetic member 320 are magnets. In this embodiment, the elastic reset member 500 is a spring. In some embodiments, the elastic reset member 500 can also be other objects that can reset after the external force is removed.

In this embodiment, two buckle members 400 are provided, enhancing the locking effect on the second buckle body 200 and preventing accidental detachment of the second buckle body 200. Correspondingly, two buckle member bodies 410 are also provided, and two pressing portions 420 and two buckle portions 430 are similarly provided. The number of buckle member bodies 410, pressing portions 420, and buckle portions 430 corresponds to the number of buckle members 400. In some embodiments, there can be one buckle member 400 provided.

In this embodiment, referring to FIG. 7, a buckle member installation groove 120 is provided on the first buckle body 100 for installing the buckle member 400. Providing an additional accommodation space on the first buckle body 100 for installing the buckle member 400 can not only ensure the overall aesthetics and structural compactness of the magnetic buckle but also further protect the buckle member 400 from falling off the first buckle body 100 due to excessive external force. The number of buckle member installation grooves 120 corresponds to the number of buckle members 400. In this embodiment, since two buckle members 400 are provided, two buckle member installation grooves 120 are also provided accordingly. In some embodiments, there can be one buckle member installation groove 120 provided.

Furthermore, referring to FIG. 7, a through-hole 140 communicating with the first groove 110 is provided in the buckle member installation groove 120 at a position corresponding to the buckle portion 430. This allows the buckle portion 430 to extend into the first groove 110 to buckle the second buckle body 200 when it resets. The through-hole 140 serves a guiding and limiting role for the buckle portion 430 to buckle the second buckle body 200.

In this embodiment, a first hanging hole 150 is provided at an end of the first buckle body 100 distant from the first groove 110, for users to hang items such as keys and ornaments.

In this embodiment, referring to FIGS. 3 and 9-10, a first guiding slope 431 ascending from left to right is provided on the surface of the buckle portion 430 facing the second buckle body 200. A second guiding slope 230 and a third guiding slope 240 are provided on the side of the end of the second buckle body 200 facing the first groove 110. The second guiding slope 230 connects with the top surface of the end of the second buckle body 200 facing the first groove 110 and inclines outwardly. The third guiding slope 240 connects with one side of the second guiding slope 230 and also inclines outwardly. The cooperation of the first guiding slope 431, the second guiding slope 230, and the third guiding slope 240 facilitates the placement of the second buckle body 200 into the first groove 110, reducing the friction and resistance encountered during this process, and making the self-locking operation smoother. In some embodiments, the end of the second buckle body 200 facing the first groove 110 can be designed with a rounded corner to reduce friction with other components.

In this embodiment, referring to FIG. 7, the buckle member body 410 is rotatably assembled on the first buckle body 100 through a rotating component. The rotating component comprises a shaft seat 610, a first installation groove 620, a shaft installation hole 630, and a shaft 640. The shaft seat 610 is provided on the surface of the buckle member body 410 facing the first buckle body 100. The first installation groove 620 is provided on the side of the first buckle body 100 facing the buckle member body 410 and accommodates the shaft seat 610. The shaft installation hole 630 is provided on the side of the first buckle body 100 facing the buckle member body 410, communicates with the first installation groove 620, and accommodates the shaft 640. The shaft 640 passes through the shaft installation hole 630 and the shaft seat 610. The cooperation of the shaft seat 610, the first installation groove 620, the shaft installation hole 630, and the shaft 640 allows the shaft seat 610 to rotate within the first installation groove 620 around the shaft 640, thereby enabling the buckle member body 410 to rotate relative to the first buckle body 100. In this embodiment, specifically, the first installation groove 620 is located within the buckle member installation groove 120, and the shaft installation hole 630 is provided on the side of the first buckle body 100 facing the buckle member body 410, located at the periphery of the first installation groove 620 and communicating with it. The ends of the shaft 640 are placed within the shaft installation holes 630 and pass through the shaft seat 610. In this embodiment, since there are two buckle member bodies 410, there are also two shaft seats 610, two corresponding shafts 640, two corresponding first installation grooves 620, and four corresponding shaft installation holes 630. In some embodiments, the number of shaft seats 610, shafts 640, first installation grooves 620, and shaft installation holes 630 is adjusted according to the number of buckle member bodies 410. In this embodiment, the magnetic buckle further comprises a cover for fixing the shaft 640 and a fastener for fixing the cover to the first buckle body 100. The cover and the fastener serve to prevent the shaft 640 from falling out. In this embodiment, the fastener is a screw. In some embodiments, the fastener can be other components used to tighten the cover.

In this embodiment, referring to FIGS. 7 and 9, a convex portion 440 protruding outwards is provided on the surface of the pressing part 420 facing away from the first buckle body 100. The convex portion 440 facilitates users to apply force and quickly locate the operating position for unlocking the first buckle body 100 and the second buckle body 200, thereby improving the accuracy and comfort of user operation.

Furthermore, referring to FIGS. 7-9, a second installation groove 421 recessed away from the first buckle body 100 is provided on the surface of the pressing part 420 facing the first buckle body 100. A third installation groove 130, which is recessed away from the pressing part 420 and corresponds in position to the second installation groove 421, is provided on the side of the first buckle body 100 facing the pressing part 420. The second installation groove 421 and the third installation groove 130 cooperate to restrict the elastic reset member 500, preventing it from falling out. At the same time, the second installation groove 421 and the third installation groove 130 provide expansion and contraction space for the elastic reset member 500. Specifically, one end of the elastic reset member 500 abuts against the inner bottom surface of the second installation groove 421, and the other end abuts against the inner bottom surface of the third installation groove 130. Additionally, the third installation groove 130 is located within the buckle installation groove 120. In some embodiments, the magnetic buckle may only be equipped with the second installation groove 421 or only the third installation groove 130.

In this embodiment, referring to FIGS. 7 and 10, an annular groove 220 engaged with the buckle portion 430 is provided on the peripheral side of the end of the second buckle body 200 facing the first groove 110, which increases the flexibility of the self-locking of the magnetic buckle. Users can engage the annular groove 220 with the buckle portion 430 without requiring a specific angle, simplifying the self-locking operation. In addition, the design of the annular groove 220 enhances the service life of the magnetic buckle and improves the reliability of the connection, avoiding excessive stress concentration in a single groove design during frequent engagement between the buckle portion 430 and the groove, which may lead to wear or deformation of the groove, reducing the stability of the connection between the buckle portion 430 and the groove.

Furthermore, referring to FIGS. 7 and 10, a second recess 210 recessed away from the first groove 110 is provided on the end of the second buckle body 200 facing the first groove 110. The second recess 210 is used to install the second magnetic member 320, preventing it from falling out. In this embodiment, a second hanging hole 250 is provided on the end of the second buckle body 200 away from the second recess 210, allowing users to hang items such as keys and decorations.
