Description

Technical Field

[0001] This utility model relates to the field of card storage technology, and in particular to an elastic retractable card holder. Background Technology

[0002] With societal development, bank cards, ID cards, and other cards have become indispensable items in people's daily lives. Traditional card holders typically use elastic bands or other elastic components to control card capacity and offer some anti-theft features. For example, Chinese utility model patent application number CN202420575072.8 discloses a portable spring card holder that uses multiple elastic components and a pull cord to ensure balance during use. However, card holders using elastic bands or other elastic components also have certain drawbacks in practical use.

[0003] The defects of its elastic band structure are as follows: 1. The joints of the elastic band are usually connected by sewing, which is prone to breakage due to friction or excessive tension after long-term use, causing the card clip to fail; 2. The elastic material of the elastic band is prone to hardening and loss of elasticity after long-term use or exposure to high temperature environment, causing the card clip to be unable to effectively clamp the card; 3. During the process of inserting and removing cards, the elastic band is prone to tilting due to uneven force, making it difficult to insert or remove the card smoothly, affecting the user experience.

[0004] The drawbacks of the elastic component structure are as follows: 1. The design of the elastic component is often too rigid, which makes it easy for the card to get stuck during the insertion process, resulting in a lack of smooth operation; 2. The manufacturing process of the elastic component is relatively complicated, especially when multiple functions are required (such as anti-theft and anti-radio frequency), which significantly increases the production cost; 3. The connection between the elastic component and the card holder body is usually fixed by mechanical means, which is prone to misalignment and detachment due to vibration or external force after long-term use, affecting stability; 4. The design of the elastic component is too mechanical, which can easily cause excessive pressure on the card, resulting in card damage or poor flexibility when removing the card. Utility Model Content

[0005] This invention proposes an elastic retractable card holder to solve the problem mentioned in the background art, which is that the existing card holders use elastic band structures or elastic element structures, resulting in a poor user experience.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A resilient retractable card holder, comprising:

[0008] There are two support plates. One end of the two support plates is rotatable and elastically connected, so that the other end of the two support plates is kept clamped in the natural state, and a receiving cavity is formed between the two support plates.

[0009] The elastic limiting member has one end connected to one of the support plates and the other end extending into the receiving cavity between the two support plates. It is used to contact the card inserted into the receiving cavity and provide a limiting effect to prevent the card from falling out.

[0010] Preferably, the elastic limiting member is a spring sheet with an arc-shaped cross-section, and the arc-shaped spring sheet extends from the middle of one of the support plates toward the connection end of the two support plates.

[0011] Preferably, the spring is a stainless steel memory spring.

[0012] Preferably, the end edges where the two support plates are connected have protrusions extending towards each other, and a pin for connecting the two support plates is installed on the protrusion, and a torsion spring is installed on the pin, so that the other end of the two support plates is clamped in a natural state.

[0013] Preferably, at least one support plate has an exterior trim panel mounted on its outer surface.

[0014] Preferably, both the support plate and the outer trim plate have notches.

[0015] Preferably, the notch is located at the end face or side face of the support plate and the outer trim panel.

[0016] Preferably, a clamp is fixed between one of the support plates and the outer trim panel.

[0017] Preferably, the inner side of the end of the support plate away from its connecting end is provided with a contact surface, and the contact surface forms an angle with the surface of the support plate. When the two support plates are naturally clamped, the contact surfaces of the two support plates can contact each other, and rounded corners are provided at the edges of the contact surfaces.

[0018] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0019] This invention significantly improves the durability and stability of the card holder by employing a stainless steel memory spring and a torsion spring structure, avoiding the problems of easy breakage of traditional elastic bands, hardening of rubber bands, and easy detachment of elastic component connections. The elastic connection design makes the card loading and unloading process smoother, effectively preventing cards from jamming or tilting, and improving the user experience. At the same time, the cooperation between the support plate and the spring enhances the card fixing effect, ensuring that the cards are firmly held in the receiving cavity and do not fall out. In addition, this invention has a simple structure, simplified production process, reduced manufacturing costs, is suitable for various card loading methods, can meet the needs of different usage scenarios, and has broad application prospects.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] As shown in the figure, a resilient retractable card holder includes:

[0029] There are two support plates 1, one end of which is rotatable and elastically connected. Specifically, the edges of the ends where the two support plates 1 are connected have protrusions 101 extending towards each other. A pin 5 for connecting the two support plates 1 is installed on the protrusion 101, and a torsion spring 4 is installed on the pin 5. The torsion spring 4 keeps the other end of the two support plates 1 in a clamped state in its natural state. That is, the two support plates 1 are rotatably connected by the pin 5, and the torsion spring 4 drives the two support plates 1 to be clamped. More specifically, in order to prevent the torsion spring 4 from moving along the axis of the pin 5, both ends of the torsion spring 4 are placed in the positioning grooves 102 opened on the side of the protrusion 101 of the support plate 1; so that the other end of the two support plates 1 is kept in a clamped state in its natural state, and a receiving cavity is formed between the two support plates 1.

[0030] An elastic limiting member has one end connected to one of the support plates 1 and the other end extending into the receiving cavity between the two support plates 1. It is used to contact the card inserted into the receiving cavity and provide a limiting effect to prevent the card from falling out.

[0031] Specifically, the elastic limiting member is a spring sheet 3 with an arc-shaped cross section. In this example, the spring sheet 3 is a stainless steel memory spring sheet 3, which has excellent elasticity and durability and can maintain a stable limiting effect during long-term use. The arc-shaped spring sheet 3 extends from the middle of one of the support plates 1 towards the connection end of the two support plates 1. This arrangement is to prevent the card from getting stuck when it is inserted into the receiving compartment 7, so that the card drives the spring sheet 3 to deform and be placed between the spring sheet 3 and one of the support plates 1, and the spring sheet 3 clamps the card.

[0032] Specifically, at least one support plate 1 has an exterior trim panel 2 installed on its outer surface. In this example, both support plates 1 have exterior trim panels 2 installed on their outer surfaces. The exterior trim panels 2 are installed on the support plates 1 by screws to protect the support plates 1 and for aesthetic purposes.

[0033] Specifically, both the support plate 1 and the outer trim plate 2 are provided with notches 8. More specifically, the notches 8 are located on the end face or side of the support plate 1 and the outer trim plate 2. For example, they can be located at the end where the support plate 1 is connected, or on the upper and lower sides of the support plate 1. They are mainly used to push the card out of the receiving compartment 7 by inserting a finger into the notch 8, so as to achieve the card retrieval effect in different directions such as pushing upwards or sideways.

[0034] Specifically, a clamp 6 is fixed between one of the support plates 1 and the outer trim panel 2. The clamp 6 can be used to fix the card in a designated position, such as the belt, so as to achieve the function of portability.

[0035] Specifically, the inner side of the end of the support plate 1 furthest from its connecting end is provided with a contact surface 103. The contact surface 103 forms an angle with the surface of the support plate 1. When the two support plates 1 are naturally clamped, the contact surfaces 103 of the two support plates 1 can contact each other. A rounded corner 104 is provided at the edge of the contact surface 103. This arrangement, on the one hand, utilizes the structural design of the contact surface 103 to allow the two support plates 1 to form surface contact during clamping, making the structure more stable and reliable. On the other hand, the structural design of the rounded corner 104 facilitates the insertion of cards between the two support plates 1, which can play a certain guiding role and improve the smoothness of card storage.

[0036] When using this resilient retractable card clip, the user simply inserts the card into the receiving cavity between the two support plates 1. The spring 3 then contacts the card and provides a limiting effect, preventing the card from falling out. When it is necessary to remove the card, the user can insert their finger into the notch 8 and push a corner of the card out of the receiving compartment 7 to easily remove the card. The design of the stainless steel memory spring 3 and the torsion spring 4 ensures that the card clip maintains stable clamping force and durability during long-term use.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
