Referring to FIGS. 1-5, a magnetic attraction structure for a toy provided in an embodiment of the present disclosure is shown, including a base 10, a shell 20, and a cover body 30 mounted between the base and the shell, and a magnetic body 40 is connected in the cover body 30. The magnetic body 40 in the embodiment has two magnetic poles with opposite magnetism. In other implementations of the present disclosure, the magnetic body 40 may also be a magnetic body with a single magnetic pole.

The base 10 is provided with a groove 11 for fixedly mounting the shell 20, so that a sealed storage space can be formed between the groove 11 and the shell 20, so as to mount both the cover body 30 and the magnetic body 40 in the storage space.

In the embodiment, an ejector block 12 extends in a protruding manner on an inner wall of the groove 11 at a position facing the magnetic body 40, the ejector block 12 abuts against the magnetic body 40 to limit the lowest position of the magnetic body 40 in the groove 11, so as to play a role of preventing the magnetic body 40 from being in direct contact with the bottom wall of the groove 11, and the cover body 30 may also be in positioning connection in the groove 11 through the ejector block 12. It should be noted that a sum of heights of the ejector block 12 and the magnetic body 40 is less than a depth of the groove 11, so that the magnetic body 40 subjected to a magnetic force or an action of gravity can move up and down in the groove 11.

A limiting ring 13 circumferentially extends in a protruding manner on an outer side of an open end of the base 10. An embedding position of the magnetic attraction structure in the toy may be limited by the limiting ring 13, so that a speed of mounting the magnetic attraction structure in the toy is increased. That is, the limiting ring 13 can be in limited connection to an outer wall of the toy, so that the open end of the base 10 may be exposed to the outer wall of the toy building block. In other implementations of the present disclosure, the base 10 may not be provided with the ejector block 12 and/or the limiting ring 13.

The shell 20 is provided with the first barrel body 21 and the second barrel body 22, and the first barrel body 21 is located in the second barrel body 22. In the embodiment, the first barrel body 21 and the second barrel body 22 are concentrically arranged on the shell 20, and the first barrel body 21 extends upward along a bottom wall of the second barrel body 22. The first barrel body 21 is of an axial penetrating structure, and a slide opening 211 is formed in a side wall of the first barrel body 21. An axial height of the second barrel body 22 is equal to the depth of the groove 11, and the second barrel body 22 is fixedly connected in the groove 11 through a buckling structure. According to the above arrangement, when the second barrel body 22 is fixed in the groove 11 through the buckling structure, an open end of the first barrel body 21 and an open end of the groove 11 are substantially located in a same plane, to ensure that when two magnetic attraction structures are connected, a gap therebetween is small enough.

In other implementations of the present disclosure, one end of the first barrel body 21 may be arranged in a protruding manner out of an end wall of the first barrel body 22. According to the structural arrangement, when the second barrel body 22 is fixed in the groove 11 through the buckling structure, an open end surface of the first barrel body 21 is parallel to an open end surface of the groove 11.

In the embodiment, at least one insertion connection opening 221 located at an outer ring of the first barrel body 21 is formed on the bottom of the second barrel body 22, and the insertion connection opening 221 is used to be fixedly connected to an insertion connection rod of an external toy in an insertion connection manner. According to the above arrangement, the magnetic attraction structure still can fixedly connect two toys (for example, two toy building blocks, and the like) by no way of the magnetic force of the magnetic body 40. In other implementations of the present disclosure, the second barrel body 20 may not be provided with the insertion connection opening 221.

The buckling structure includes a buckle body and a connector separately arranged between the second barrel body 22 and the groove 11, and the buckle body may be buckled in the connector. By arranging the buckling structure, during assembly, the shell 20 is pressed in the groove 11, so that the two are fixed fast. The mounting mode is convenient and fast, which contributes to increasing the mounting speed of the magnetic attraction structure.

In the embodiment, the buckle body includes a first buckle body 51 extending upward along a bottom wall of the groove 11, the connector includes a first connector 52 formed, corresponding to the first buckle body 51, in a side wall of the second barrel body 22, and the first buckle body 51 is extendable between the first barrel body 21 and the second barrel body 22, so that the first buckle body 51 may be buckled in the first connector 52. It should be noted that the first buckle body 51 is provided with a protruding part 500 extending in a protruding manner toward a direction of the first connector 52, the protruding part 500 is an arc-shaped body (or wedge-shaped body), and the protruding part 500 is used to clamp the first buckle body 51 in the first connector 52. Specifically, since the first buckle body 51 has a rod body extending upward along the bottom wall of the groove 11, the rod body subjected to an extrusion force can deform slightly and the rod body is reset to complete the buckling operation till the protruding part 500 thereof is opposite to the first connector 52.

In other implementations of the present disclosure, for example, the second embodiment shown in FIGS. 6 and 7, the buckle body includes a second buckle body 53 arranged on an outer side wall of the second barrel body 22, the connector includes a second connector 54 arranged corresponding to the second buckle body 53 on a side wall of the groove 11, and when the second barrel body 22 is completely stored in the groove 11, the second buckle body 53 may be buckled in the second connector 54. In the second embodiment, the second buckle body 53 as a whole is the protruding part 500, and the protruding part 500 is arranged in a wedge-shaped structure, so that the second buckle body 53 can be more firmly connected in the second connector 54. In other implementations, the buckle body simultaneously includes the first buckle body 51 and the second buckle body 53, and the connector simultaneously includes the first connector 52 and the second connector 54.

It should be noted that a length of the protruding part 500 in the first buckle body 51 is set equal or approximately equal to an opening length of the first connector 52, and a length of the protruding part 500 in the second buckle body 53 is set equal or approximately equal to an opening length of the second connector 54. According to the above arrangement, the shell 20 may be prevented from rotating relatively in the groove 11.

The cover body 30 is of a hollow structure opened in at least one end, so that the magnetic body 40 may enter an inner cavity of the cover body 30 through an open end of the cover body 30. In the embodiment, a size of the inner cavity of the cover body 30 is equal to or greater than an excircle diameter of the magnetic body 40, so that the magnetic body 40 can turn freely in the inner cavity of the cover body 30, so that the magnetic body can be turned and transformed correspondingly as the magnetism of the magnetic pole of the magnetic body 40 toward the outer end is different from that of another magnetic body 40 connected therewith. In other implementations of the present disclosure, the size of the inner cavity of the cover body 30 may be less than the excircle diameter of the magnetic body 40, so that the magnetic body 40 is fastened in the cover body 30, and the magnetic attraction structure of this structure only has single magnetism and may only be magnetically fixed with another magnetic attraction structure with opposite magnetism.

A slide block 31 movably connected in the slide opening 211 extends in a protruding manner on a side wall of the cover body 30, so that the cover body 30 may move up and down in the first barrel body 21. A gear ring 32 is arranged at an end wall of the cover body 30, the gear ring 32 may be pushed by the magnetic body 40 to be exposed out of the first barrel body 21, and the gear ring 32 can be meshed with a gear ring of another magnetic attraction structure, so that the two magnetic attraction structures are fastened and connected to prevent dislocation. It may be understood that according to the arrangement that the gear ring 32 is fixedly arranged on the end wall of the cover body 30 and may move up and down along with the cover body 30, on the one hand, when the two magnetic attraction structures are separated, the gear ring 32 subjected to gravity may fall back into the first barrel body 21, so that the speed at which the gear ring 32 is worn and damaged is decreased, and the service life of the magnetic attraction structure is prolonged. On the other hand, the structure of the cover body 30 may also be optimized, and the number of assembly parts of the magnetic attraction structure is reduced, which contributes to improving the production and assembly efficiencies.

In the embodiment, the cover body 30 is further provided with a through hole 33 in a middle of the gear ring 32, and an opening size of the through hole 33 is less than a size of the magnetic body 40, so as to, on the premise of preventing the magnetic body 40 from being unable to be separated from the cover body 30, increase the ability of the magnetic body 40 sensing an external magnetic force. In other implementations of the present disclosure, the end wall of the cover body 30 provided with the gear ring 32 may also be referred to as a closed structure.

In order to improve the connecting compactness between the base 10 and the shell 20 to further prevent the shell 20 from rotating circumferentially in the base 10, in the embodiment, the base 10 and the second barrel body 22 are further connected through a positioning structure. The positioning structure includes a positioning strip 61 and a positioning opening 62 separately arranged between the groove 11 and the second barrel body 22, and the positioning strip 61 and the positioning opening 62 are adapted in shape and match with each other in an insertion connection manner. In other implementations of the present disclosure, the positioning structure is not arranged between the base 10 and the second barrel body 22.

When the magnetic attraction structure provided by the present disclosure is assembled, it is only needed to place the magnetic body 40 in the cover body 30 and place the cover body 30 in the first barrel body 21, and then press the base 10 and the second barrel body 22 oppositely to buckle the two. Compared with the existing structure, the magnetic attraction structure provided by the present disclosure features few assembly steps and a simple and convenient assembly process, so that the production and assembly efficiencies of the magnetic attraction structure may be effectively improved.

For clarity, some features described in independent embodiments of the present disclosure may be combined in a single embodiment for use. Moreover, various features of the present disclosure described in the single embodiment may also be used independently or in combination in any appropriate form.
