Description

Technical Field

[0001] The invention relates to the technical field of credit card storage, in particular to a snap-on damper card box. Background Art

[0002] In order to prevent the cards from being thrown out after being inserted into the existing credit card ejection box, most of them have flexible dampers (silicone, felt cloth, cotton cloth, sponge, etc.) installed on both sides of the card box to increase the damping by using the friction between the card and the card. When more cards are inserted into the card box, the friction is greater and the card ejection is more difficult. Therefore, it is necessary to develop a damper whose damping size is less affected by the number of cards. Summary of the invention

[0003] 1. Technical issues to be resolved In view of the deficiencies of the prior art, the present invention provides a snap-on damper card box, which solves the problem that after a plurality of cards are added to the prior card box, the friction force is relatively large and the card ejection is relatively difficult.

[0009] Beneficial Effects The present invention provides a snap-on damper cartridge having the following beneficial effects: 1. The present invention arranges a bump damper on the mounting frame.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0015] like Figure 1-7 As shown, the embodiment of the present invention provides a snap-on damper card box, including a card box box 1 and a spring 18. Limiting grooves 2 are provided on the front and rear inner walls of the card box box 1. The setting of the limiting grooves 2 is mainly used to limit the position of the mounting frame 3 to prevent the mounting frame 3 from moving inside the card box box 1. The mounting frame 3 is provided inside the limiting grooves 2. The right end of the mounting frame 3 is fixedly connected with a bump damper 4. The flexible damper 17 is made of silicone or other soft materials. This structural design can effectively protect and push the card, which is convenient for users to store and take out, and significantly improves the practical performance of the card box. When the card is pushed in, the bump damper 4 undergoes elastic deformation, and the reaction force of the bump damper 4 is used to squeeze the card to prevent the card from being thrown out when the card box is subjected to a large swing. When the card is pushed out, the force required for the bump damper 4 to further undergo elastic deformation is equal to the number of cards. It is irrelevant, so it is relatively easy to push out multiple cards. Unlike the common flexible damper card box on the market, the left inner wall of the mounting frame 3 is fixedly connected with a base plate 19 and a hook 5, and the hook 5 is located above the base plate 19, and the top of the base plate 19 is fixedly connected with a rotating shaft 6, and the bottom of the rotating shaft 6 is rotatably connected with a swing arm 7 and is provided with a hanging hole 8. One end of the spring 18 is fixed on the hook 5, and the elastic force of the spring 18 is used to provide the swing arm 7 with the power required for resetting. When the swing arm 7 is reset, the swing shaft protrusion thereon collides with the transmission groove on the transmission rod 11, thereby driving the transmission rod 11 and the sliding button 13 to reset together, and the other end of the spring 18 is fixedly connected to the hanging hole 8, and the rear side wall of the swing arm 7 is fixedly connected with a step spacer 9. The setting of the step spacer 9 can effectively support multiple cards, ensuring that the cards can be pushed out in sequence and orderly.

[0016] A first sliding groove 10 is provided on the front side wall of the mounting frame 3, and a transmission rod 11 is slidably connected inside the first sliding groove 10. A card slot 12 is provided on the side wall of the transmission rod 11. A second sliding groove 15 is provided on the front side wall of the card box 1. A sliding button 13 is provided on the front side of the card box 1. The sliding button 13 is mainly used to control the transmission rod 11 to move to the left, and to squeeze the swing arm 7 to rotate the swing arm 7, thereby pushing the card out. A clamping buckle 14 is fixedly connected to the bottom of the sliding button 13. The sliding button 13 is fixedly connected to the transmission rod 11 through the clamping buckle 14 and the card slot 12, and the clamping buckle 14 is located inside the second sliding groove 15.

[0017] A deformation block 16 is provided on the rear inner wall of the mounting frame 3 , and a flexible damper 17 is fixedly connected to the deformation block 16 .

[0018] The bump damper 4 and the mounting frame 3 are integrally formed of ABS material, and the structure is similar to a buckle. When the card is stored in the card box 1, the bump damper 4 is like a buckle, firmly clamping the card. In addition, during the card storage process, the transmission rod 11 is driven to reset, and its top contacts the bump damper 4, effectively limiting the elastic deformation of the bump damper 4, thereby enhancing the buckle effect and further ensuring that the card is firmly clamped. The deformation block 16 and the mounting frame 3 are integrally formed of ABS material. In order to prevent the card box 1 from exerting excessive force on the card at the stepped spacer 9 of the swing arm 7 after the bump damper 4 undergoes maximum elastic deformation during the card ejection process, causing the card to fly out of the card box 1 (i.e., the "flying card" phenomenon), a flexible damper 17 is specially designed to increase the damping effect, and the number of the clamping buckle 14 and the card slot 12 is two, and the clamping buckle 14 and the card slot 12 are arranged correspondingly, a swing shaft bump is arranged at the front end of the swing arm 7, a rotating groove is arranged at the left end of the transmission rod 11, and the swing shaft bump is located inside the rotating groove.

[0019] Working principle: When in use, place the card properly inside the card box 1 to achieve effective protection of the card. When the card needs to be used, the card ejection mechanism can be started by pushing the sliding button 13 to slide in the first sliding groove 10. At this time, the sliding of the sliding button 13 drives the transmission rod 11 to move, causing the swing shaft protrusion to collide with the rotating groove, thereby pushing the swing arm 7 to rotate along the rotating shaft 6. The rotating swing arm 7 drives the step spacer 9 to rotate inside the card box 1, and the cards are ejected from the card box 1 in batches and in an orderly manner. During the card ejection process, since the transmission rod 11 moves to the left, it no longer restricts the protrusion damper 4, allowing it to have more elasticity. When the card moves to the right, the bump damper 4 is forced to further deform elastically, causing its snap function to fail, thereby ensuring that the card can be pushed out smoothly. At the same time, the flexible damper 17 and the deformation block 16 continue to play a role, effectively preventing the longest part of the swing arm 7 from exerting too much force on the card, and preventing the card from flying out of the card box 1. When the card is taken out, release the sliding button 13. In the absence of external force, the elastic force of the spring 18 resets the swing arm 7. When the swing arm 7 is reset, the swing shaft bump collides with the rotating groove again, driving the transmission rod 11 and the sliding button 13 to reset together. Finally, manually push the card back into the card box to complete the entire workflow.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
