Top columns 25 and first springs 26 are movably mounted in the first assembly holes 24. The first springs 26 elastically abut against the top columns 25. The top columns 25 match the limiting recesses 21. The extension blocks 20 are provided with second assembly holes 27. Balls 28 and second springs 29 are movably mounted in the second assembly holes 27. The second springs 29 elastically abut against the balls 28. The balls 28 match the first blind holes 22 or the second blind holes 23. The card pusher 13 is provided with a card support 30 and a passive pushing block 31. The passive pushing block 31 abuts against the active pushing block 9. The card pusher 13 is provided with a recess 32. The housing 1 is provided with an arc-shaped sinking recess 33. The first side plate 3 is provided with an accommodation recess 34. The second side plates 4 are provided with assembly recesses 35. Flexible friction members 36 are fixedly mounted in the assembly recesses 35.

Through the technical solution, according to the present disclosure, the cover plate 2 is provided with the transition ring 7 and the assembly ring 8, and the assembly ring 8 is movably provided with the pressure relief wheel 11 by means of the bearing 10, such that the pressure relief wheel 11 is rotatable, the transition ring 7 enables better transition between an end surface of the cover plate 2 and the pressure relief wheel 11, and a feeling of playing is improved. During playing, a user can become relaxed by rotating the pressure relief wheel 11, or placing the pressure relief wheel 11 on a hand so as to rotate the card holder.

According to the present disclosure, the cover plate 2 and the housing 1 are both rigid, such that a user can enable the cover plate 2 and the housing 1 to slide relatively by sliding the cover plate 2, so as to quickly open or close the card holder. The rigid cover plate 2 and the rigid housing 1 can protect cards in the card holder, so as to prevent the cards from being deformed.

According to the present disclosure, the housing 1 is movably provided with the card pusher 13 by means of the shaft 12. That is, the card pusher 13 may rotate around the shaft 12. The card pusher 13 is provided with the card support 30 and the passive pushing block 31. The card support 30 is configured to accommodate the cards. When the card holder is opened, the cover plate 2 and the housing 1 slide relatively, and the active pushing block 9 of the cover plate 2 pushes the passive pushing block 31 of the card pusher 13, such that the card support 30 pushes the cards out of the card holder, facilitating user access to the cards.

Example 2:

As shown in FIGS. 1-16, a card holder provided by the present disclosure includes a housing 1 and a cover plate 2. The housing 1 is provided with a first side plate 3 and is symmetrically provided with second side plates 4. That is, on a same end surface of the housing 1, the second side plates 4 are symmetrically arranged, the first side plate 3 is arranged, and the first side plate 3 is perpendicular to the second side plates 4, such that the first side plate and the second side plates constitute an approximately U-shaped structure. (Herein, the U indicates that the first side plate 3 and two symmetrical second side plates 4 define an approximately U-shaped structure, with the aim of describing the structure more vividly. A bottom of the U is the first side plate 3, symmetrical sides of the U are the second side plates 4, an opening of the U is an opening position of the card holder, and an interior of the U is configured to store cards.) Moreover, the first side plate 3 and the second side plates 4 are all arranged at side edges of the housing 1.

The second side plates 4 are provided with sliding bars 5. The cover plate 2 is symmetrically provided with sliding recesses 6 (the sliding recesses 6 are parallel to the sliding bars 5). The sliding bars 5 are slidably connected to the sliding recesses 6. That is, the cover plate 2 is slidably fixed to the housing 1 by means of a sliding rail structure, such that opening and closing of the card holder are facilitated.

The cover plate 2 is slidably fixed to the housing 1 by means of the sliding rail structure, and the cover plate 2 and the housing 1 may slide relatively, such that the card holder of the present disclosure has an open state and a closed state.

The card holder of the present disclosure is opened as follows: a user applies an acting force to the cover plate 2, and with respect to the U, a direction of the acting force is oriented from an opening position of the card holder to the first side plate 3. In this case, the housing 1 is fixed or a force opposite to the acting force is applied, such that the cover plate 2 and the housing 1 slide relatively, and an opening operation of the card holder of the present disclosure is completed.

The card holder of the present disclosure is closed as follows: a user applies an acting force to the cover plate 2, and with respect to the U, a direction of the acting force is oriented from a third side plate to an opening position of the card holder. In this case, the housing 1 is fixed or a force opposite to the acting force is applied, such that the cover plate 2 and the housing 1 slide relatively, and a closing operation of the card holder of the present disclosure is completed.

The cover plate 2 is provided with a transition ring 7, an assembly ring 8 and an active pushing block 9. The transition ring 7 and the assembly ring 8 are concentric rings, and the assembly ring 8 is located in the transition ring 7. An end surface of the transition ring 7 is a smooth curved surface. The transition ring 7 enables better transition between an end surface of the cover plate 2 and a pressure relief wheel 11, and a feeling of playing is improved. The assembly ring 8 is movably provided with the pressure relief wheel 11 by means of a bearing 10. During playing, a user can become relaxed by rotating the pressure relief wheel 11, or placing the pressure relief wheel 11 on a hand so as to rotate the card holder.

The housing 1 is movably provided with a card pusher 13 by means of a shaft 12. That is, the card pusher 13 may rotate around the shaft 12. The card pusher 13 is provided with a card support 30 and a passive pushing block 31. The card support 30 is configured to accommodate cards. When the card holder is opened, the cover plate 2 and the housing 1 slide relatively, and the active pushing block 9 of the cover plate 2 pushes the passive pushing block 31 of the card pusher 13, such that the card support 30 pushes the cards out of the card holder, facilitating user access to the cards.

In one embodiment (FIGS. 1-5), the housing 1 is symmetrically provided with two shafts 12, and each of the shafts 12 is movably provided with a card pusher 13. The card pushers 13 are symmetrically arranged.

In another embodiment (FIGS. 11-15), the housing 1 is provided with only one shaft 12, and the shaft 12 is movably provided with a card pusher 13.

The card pusher 13 is provided with the card support 30 and the passive pushing block 31. The card pusher 13 may rotate around the shaft 12, and the shaft 12 is located between the card support 30 and the passive pushing block 31. In this way, the card pusher 13 forms a lever structure with the shaft 12 as a supporting point, and the passive pushing block 31 abuts against the active pushing block 9 of the cover plate 2.

In a process of opening the card holder of the present disclosure, the cover plate 2 and the housing 1 slide relatively, and the active pushing block 9 of the cover plate 2 pushes the passive pushing block 31 to move toward the first side plate 3. The card pusher 13 is of a lever structure. Thus, the card support 30 moves toward the opening position of the card holder, and the card support 30 pushes the cards to move toward the opening position of the card holder, such that the cards are pushed out to facilitate user access to the cards, and convenience of the card holder is improved.

On the basis of the process of opening the card holder, in a process of closing the card holder of the present disclosure, a user presses the cards back into the card holder, and the card pusher 13 is reset under the action of thrust of the cards. In this case, the passive pushing block 31 pushes the active pushing block 9 so as to reset the cover plate 2, such that the process of closing the card holder is completed.

Example 3:

As shown in FIGS. 2, 3, 6, 7, 12 and 13, on the basis of Example 2, the present disclosure further adds a card tape structure, such that it is convenient for a user to temporarily accommodate cards. Specifically, second side plates 4 are provided with connecting parts 14. (A housing 1 is symmetrically provided with the second side plates 4. That is, the housing 1 is provided with the two second side plates 4. In the example, each of the second side plates 4 is provided with the connecting part 14.) The connecting parts 14 are extension parts of the second side plates 4 and are integrated with the second side plates 4. (However, in some implementations processes, the connecting parts 14 and the second side plates 4 are separate mechanisms and are fixed by means of bolts or through clamping.) The connecting parts 14 are fixedly provided with a card tape by means of connecting rods 15. The card tape is a soft strip that is wound around the connecting rods 15 of the two connecting parts 14 separately, so as to form an annular card tape. Two ends of the card tape are fixedly connected to each other by means of an engagement member 17. After the card tape is formed into an annular shape, two narrow gaps may be formed. (That is, the card tape formed into an annular shape is divided into a lower card tape and an upper card tape, where the lower card tape and a surface of the housing 1 constitute a narrow gap, and the lower card tape and the upper card tape constitute a narrow gap.) The user may insert a card into any narrow gap, so as to achieve a function of temporarily storing cards.

In a process of using a card holder, after a card is taken out of the card holder and used, the card possibly needs to be used again in a short time. If the card is taken out and put in frequently, the card is inconvenient to use. However, if the card is directly held in a hand, the card is easy to lose. For instance, people need to swipe a card twice for high-speed rail ticket checking. According to the present disclosure, the card holder forms two narrow gap structures by means of the card tape structure. In a case that the user needs to temporarily store a card, the card is inserted into any narrow gap, such that a function of temporarily and quickly storing the card is achieved. The user may also carry banknotes during travel. The formed narrow gap may be further configured to clamp banknotes or other small objects, such that use functions of the card holder are further expanded.

Example 4:

As shown in FIGS. 6 and 7, on the basis of Example 3, the present disclosure further technically optimizes an engagement member 17, so as to improve structural stability of an annular card tape. The engagement member 17 is symmetrically provided with pressure plates 18. The pressure plates 18 are provided with tooth parts 19. The engagement member 17 is made of metal, such as copper and alloy. During assembly, the pressure plates 18 are pressed on two ends of the card tape, and the tooth parts 19 of the pressure plates 18 penetrate the card tape, such that two ends of the card tape are stably connected together so as to form the annular card tape.

Example 5:

As shown in FIGS. 3, 4, 5, 13, 14 and 15, on the basis of Example 2, the present disclosure further optimizes sliding limiting and sliding feeling between a cover plate 2 and a housing 1. Specifically, second side plates 4 are provided with extension blocks 20. The extension blocks 20 are structures, protruding toward an interior of a card holder, of the second side plates 4 and are located at junctions of the second side plates 4 and a first side plate 3. The extension blocks 20 are provided with first assembly holes 24 and second assembly holes 27.

Bottoms of the first assembly holes 24 are provided with first springs 26. Top columns 25 are movably mounted at openings of the first assembly holes 24. The first springs 26 elastically abut against the top columns 25. The top columns 25 have an elastic extension and retraction function.

Bottoms of the second assembly holes 27 are provided with second springs 29. Balls 28 are movably mounted at openings of the second assembly holes 27. The second springs 29 elastically abut against the balls 28. The balls 28 have an elastic extension and retraction function.

The cover plate 2 is provided with limiting recesses 21, first blind holes 22 and second blind holes 23.

Aft that cover plate 2 and the housing 1 are assembled, the top columns 25 are located in the limiting recesses 21. When the cover plate 2 and the housing 1 slide relatively, the top columns 25 match the limiting recesses 21, such that a sliding distance of the cover plate 2 relative to the housing 1 is limited, and the cover plate 2 is prevented from being separated from the housing 1. Centers of the first blind holes 22 and the second blind holes 23 are connected to form an auxiliary straight line L. The auxiliary straight line L is parallel to a length direction of the limiting recesses 21. When the cover plate 2 and the housing 1 slide relatively, the balls 28 have an elastic trend of popping out of the second assembly holes 27 under the action of the second springs 29, and the balls 28 match the first blind holes 22 or the second blind holes 23. When the card holder is closed, the balls 28 are bounced into the first blind holes 22 (part of the balls 28 enters the first blind holes 22, and the part is smaller than half of the ball 28), such that a function of temporarily fixing the cover plate 2 and the housing 1 is achieved. When the card holder is open, the balls 28 are bounced into the second blind holes 23 (part of the balls 28 enters the second blind holes 23, and the part is smaller than half of the ball 28), such that a function of temporarily fixing the cover plate 2 and the housing 1 is achieved.

The top columns 25 match the limiting recesses 21, such that a sliding range of the cover plate 2 and the housing 1 is limited. The balls 28 match the first blind holes 22 or the second blind holes 23, such that the cover plate 2 and the housing 1 may be temporarily fixed at limiting positions, thus improving a sliding feeling of the card holder.

Example 6:

As shown in FIGS. 3, 4, 8, 9, 13 and 14, on the basis of Example 2, the present disclosure further optimizes a structure of a card pusher 13.

The card pusher 13 is provided with a card support 30 and a passive pushing block 31. The card pusher 13 may rotate around a shaft 12, and the shaft 12 is located between the card support 30 and the passive pushing block 31. In this way, the card pusher 13 forms a lever structure with the shaft 12 as a supporting point, and the passive pushing block 31 abuts against an active pushing block 9 of a cover plate 2.

In a process of opening the card holder of the present disclosure, the cover plate 2 and a housing 1 slide relatively, and the active pushing block 9 of the cover plate 2 pushes the passive pushing block 31 to move toward the first side plate 3. The card pusher 13 is of a lever structure. Thus, the card support 30 moves toward an opening position of the card holder, and the card support 30 pushes the cards to move toward the opening position of the card holder, such that the cards are pushed out to facilitate user access to the cards, and convenience of the card holder is improved.

The card support 30 is uniformly provided with a stepped structure. A height of each step approximately equals a thickness of one card. (A number of steps corresponds to a number of cards that the card holder is capable of accommodating.) Distances between the steps and a pushing rod are uniformly reduced from a maximum distance between a step close to the housing 1 and the pushing rod 12 to a minimum distance between a step close to the cover plate 2 and the pushing rod 12. After the card support 30 pushes cards to move toward the opening position of the card holder, the cards are arranged in a stepped shape, such that it is convenient for a user to visually identify and take out a required card.

On the basis of the process of opening the card holder, in a process of closing the card holder of the present disclosure, a user presses the cards back into the card holder, and the card pusher 13 is reset under the action of thrust of the cards. In this case, the passive pushing block 31 pushes the active pushing block 9 so as to reset the cover plate 2, such that the process of closing the card holder is completed.

The card pusher 13 is provided with a recess 32, and the housing 1 is provided with an arc-shaped sinking recess 33. The recess 32 and the arc-shaped sinking recess 33 are both located between contact surfaces of the card support 30 and the housing 1. Through a structure of the recess 32 and the arc-shaped sinking recess 33, contact surfaces between the card pusher 13 and the housing 1 are reduced (friction is reduced), and the card pusher 13 can rotate more smoothly.

The first side plate 3 is provided with an accommodation recess 34, and the accommodation recess 34 is configured to accommodate the passive pushing block 31. In a process of opening the card holder of the present disclosure, the cover plate 2 and a housing 1 slide relatively, and the active pushing block 9 of the cover plate 2 pushes the passive pushing block 31 to move toward the first side plate 3. The card pusher 13 is of a lever structure. Thus, the card support 30 moves toward the opening position of the card holder, and the card support 30 pushes the cards to move toward the opening position of the card holder. The accommodation recess 34 is provided to expand a rotation range of the passive pushing block 31. That is, a distance of pushing the cards to the opening position of the card holder by the card support 30 is increased, such that user access to the cards is facilitated.

Example 7:

As shown in FIGS. 3, 4, 13 and 14, on the basis of Example 2, the present disclosure further optimizes performance of a card holder. Specifically, second side plates 4 are provided with assembly recesses 35, and flexible friction members 36 are fixedly mounted in the assembly recesses 35. A material of the flexible friction members 36 may be any flexible material capable of generating large friction, and includes, but is not limited to, silica gel and other such materials. If cards are stored in a housing 1, movement of the cards may be limited by means of the flexible friction members 36. In this way, a problem that a card not stressed directly falls out of a card holder and is damaged if an opening of the card holder is inadvertently placed downward is avoided.

The flexible friction members 36 are provided with bristles densely arranged. If a plastic card tends to move, the card needs to overcome physical resistance of the bristles. In addition, due to elasticity of the flexible friction members 36, when the card makes contact with the flexible friction members and moves, certain friction may be generated between the card and the flexible friction members. The card may be prevented from sliding freely, and a problem that the card may fall out directly if the opening of the card holder is downward is effectively solved. Moreover, due to softness of the flexible friction members 36, when a person applies a force to push the card out of the housing 1 so as to drive the card to directly break through the flexible friction members 36, an appearance of the card cannot be scratched or damaged, such that certain practicability is achieved.

Example 8:

As shown in FIGS. 1, 3, 10, 11, 13 and 16, on the basis of Example 2, the present disclosure further optimizes a structure of a pressure relief wheel 11, such that pressure relief wheels 11 with different feelings of playing may be provided.

According to the present disclosure, during playing, a user can become relaxed by rotating the pressure relief wheel 11, or placing the pressure relief wheel 11 on a hand so as to rotate the card holder.

In one embodiment, an end surface of the pressure relief wheel 11 is an umbrella-shaped surface, and a top of the pressure relief wheel is a spherical surface. For the designed pressure relief wheel 11, when the pressure relief wheel 11 is rotated by a finger, a desirable feeling of playing is achieved.

In another embodiment, an end surface of the pressure relief wheel 11 is provided with an annular recess, and a center of the pressure relief wheel is a spherical surface. For the designed pressure relief wheel 11, when the pressure relief wheel 11 is rotated by a finger or the pressure relief wheel 11 is placed on a hand so as to rotate the card holder, a desirable feeling of playing is achieved.

It should be noted that relational terms herein such as first and second are only used to distinguish one entity or operation from another entity or operation without necessarily requiring or implying any actual such relation or order between such entities or operations. In addition, terms “include”, “comprise”, “involve”, or any other variations thereof are intended to cover non-exclusive inclusions, such that a process, a method, an article, or an apparatus including a series of elements not only includes those elements, but also includes other elements that are not explicitly listed, or also includes inherent elements of the process, the method, the article, or the apparatus. Without more restrictions, the elements defined by the sentence “including a ...” do not exclude the existence of other identical elements in the process, method, article, or apparatus including the elements.

What are described above are merely intended to describe the technical solution of the present disclosure instead of limiting the technical solution of the present disclosure. Modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present disclosure should fall within the scope of the claims of the present disclosure, as long as the modifications or equivalent replacements do not depart from the spirit and scope of the technical solution of the present disclosure.
