Description

Technical Field

[0001] This utility model relates to the technical field of document holder products, and specifically to a magnetic document holder for holding sheet materials such as documents and cards. Background Technology

[0002] Various ID cards and card holders are widely used in service industries or enterprises to store ID cards as work permits or temporary access passes, or to display advertising materials, etc.

[0003] Currently, these types of document card holders are mostly made of transparent plastic, typically consisting of an upper panel and a lower panel that are connected by snaps or hinges. A gap is left between the upper and lower panels after they are joined, allowing documents, advertising brochures, or other cards to be placed inside.

[0004] For card holders using a pivot connection, employing an independent pivot structure would result in a complex product structure. If the pivot connection is directly achieved using the material itself, the connection point is prone to breakage during use due to insufficient material strength. This is illustrated by patent document CN218682570U, which discloses a "novel multifunctional card holder."

[0005] While the structure of card holders using a snap-on mechanism is simple, the snap-on design typically employs an inverted snap-on structure, making separation difficult once the upper and lower panels are snapped together. This makes it challenging for users to change documents, and the snaps are prone to breakage during separation. For example, patent document CN214904370U discloses a "sliding cover card holder."

[0006] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a magnetic card holder that facilitates the replacement of identification documents.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A magnetic card holder includes a first card plate and a second card plate, which are nested together to form a thin space for accommodating documents or cards. The first card plate forms an accommodating space by a frame protruding from its edge, and a protrusion is formed along the inner edge of the frame in the accommodating space. The shape of the second card plate corresponds to the accommodating space. The second card plate located in the accommodating space abuts against the protrusion, and a boss is formed on the inner surface of the second card plate corresponding to the space enclosed by the protrusion. The thickness of the boss is less than the height of the space enclosed by the protrusion, and the gap between the two constitutes the thin space. An upper card groove is formed on the upper side of the frame of the first card plate, and a lower card hole is formed on the lower side of the frame. An upper card block is formed on the upper edge of the second card plate that extends outward and cooperates with the upper card groove, and a lower card block is formed on the lower edge of the second card plate that engages with the lower card hole. Upper magnets and lower magnets that attract each other are fixed on the opposite inner surfaces of the first card plate and the second card plate, respectively.

[0009] Furthermore, in the above technical solution, an upper flange is formed on the inner surface of the first card plate near the upper card slot, and the upper magnet is fixed inside the upper flange; a lower flange is formed on the inner surface of the second card plate corresponding to the upper flange, and the lower magnet is fixed inside the lower flange; when the first card plate and the second card plate are nested together, the upper flange is sleeved outside the lower flange, and the upper magnet and the lower magnet are close to each other and attracted.

[0010] Furthermore, in the above technical solution, the upper flange surrounds and forms a circular groove corresponding to the shape of the lower flange, and an upper magnet groove for accommodating the upper magnet is provided on the bottom surface of the circular groove.

[0011] Furthermore, in the above technical solution, the lower flange is circular, and a lower magnet groove for accommodating the lower magnet is formed on the lower flange.

[0012] Furthermore, in the above technical solution, a middle protruding strip is provided in the space enclosed by the protrusion; a gap groove is formed at the position of the protrusion corresponding to the protruding strip; in the nested engagement state of the first card plate and the second card plate, the middle protruding strip and the gap groove are nested together.

[0013] Furthermore, in the above technical solution, the upper card slot is a notch formed in the frame of the first card plate, and a baffle is integrally formed inside the upper card slot, the upper surface of which is lower than the surface of the frame of the first card plate.

[0014] Furthermore, in the above technical solution, the protrusion is an inclined surface, that is, the thickness of the protrusion gradually increases from the inner edge of the frame inward.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0016] 1. The first card plate and the second card plate in this utility model are nested together by magnetic attraction and snap-fit ​​structure. This not only ensures that the first card plate and the second card plate are firmly connected, but also allows the first card plate and the second card plate to be quickly separated by magnetic attraction when it is necessary to change the document. Its structure is simple and this utility model has a strong market competitiveness.

[0017] 2. The upper and lower flanges of this utility model are used to install magnets and also have a nesting and fastening function, further ensuring the stability of the combination of the document card sleeve. Attached Figure Description

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] This utility model is a magnetic card holder, see Figures 1 to 4 As shown, this is an embodiment of the present invention, which includes: a first card plate 1 and a second card plate 2, which are nested together to form a thin space 100 for accommodating documents or cards.

[0025] The first card plate 1 forms an accommodating space 10 by a frame 11 protruding from its edge, and a protrusion 12 is formed along the inner edge of the frame 11 in the accommodating space 10. The second card plate 2 corresponds in shape to the accommodating space 10, and the second card plate 2 located within the accommodating space 10 abuts against the protrusion 12. Furthermore, a boss 22 is formed on the inner surface of the second card plate 2, corresponding to the space enclosed by the protrusion 12. The thickness of the boss 22 is less than the height of the space enclosed by the protrusion 12, and the gap between the two constitutes the thin space 100.

[0026] The protrusion 12 is an inclined surface, meaning its thickness gradually increases inward from the inner edge of the frame 11. This structure not only saves manufacturing materials and facilitates injection molding and demolding, but also creates a gap between the protrusion 12 and the inner surface of the second plate 2 when the first and second plates 1 are nested together. This avoids vacuum adsorption caused by direct planar bonding, which would make it difficult to separate the first and second plates 1 and 2.

[0027] The upper side of the frame 11 of the first card plate 1 forms an upper card groove 111, and the lower side of the frame 11 has a lower card hole 112. The upper edge of the second card plate 2 forms an upper card block 211 that extends outward and cooperates with the upper card groove 111, and the lower edge of the second card plate 2 forms a lower card block 212 that engages with the lower card hole 112.

[0028] Specifically, the upper slot 111 is a notch formed in the frame 11 of the first card plate 1. A baffle 1110 is integrally formed inside the upper slot 111. The upper surface of the baffle 1110 is lower than the surface of the frame 11 of the first card plate 1. The notch and the baffle 1110 together form the upper slot 111 for accommodating the upper card block 211. The baffle 1110 is used because this invention typically uses injection molding of plastic material. For aesthetic purposes, the frame 11 is very thin, usually 2-3 mm. Directly creating a notch in the frame 11 of the first card plate 1 can easily lead to insufficient strength at the notch, making it prone to deformation and resulting in unstable engagement when nested with the first card plate 1 and the second card plate 2. Therefore, the integrally formed baffle 1110 is added to compensate for the insufficient strength of the frame 11 caused by the notch. Simultaneously, the baffle 1110 also provides support, supporting the second card plate 2 near the upper slot 111.

[0029] In this invention, upper magnets 31 and lower magnets 32, which attract each other, are fixed to the inner surfaces of the first card plate 1 and the second card plate 2, respectively. Specifically, an upper flange 13 is formed on the inner surface of the first card plate 1 near the upper card slot 111, and the upper magnet 31 is fixed inside the upper flange 13; a lower flange 23 is formed on the inner surface of the second card plate 2 at the position corresponding to the upper flange 13, and the lower magnet 32 ​​is fixed inside the lower flange 23.

[0030] The upper flange 13 forms a circular groove 131 corresponding to the shape of the lower flange 23, and an upper magnet groove 132 for accommodating the upper magnet 31 is provided on the bottom surface of the circular groove 131. The lower flange 23 is circular, and a lower magnet groove 231 for accommodating the lower magnet 32 ​​is provided on the lower flange 23.

[0031] When the first card plate 1 and the second card plate 2 are nested together, the upper flange 13 is sleeved outside the lower flange 23 to form a sleeve engagement. At the same time, the upper magnet 31 and the lower magnet 32 ​​are close to each other and magnetically attracted to each other, thereby ensuring the stability of the nested engagement of the first card plate 1 and the second card plate 2.

[0032] Furthermore, a central ridge 14 is provided within the space enclosed by the protrusion 12, dividing the space into a first space 101 and a second space 102. A partition groove 24 is formed on the boss 22 corresponding to the position of the ridge 14, dividing the boss 22 into a first boss 221 and a second boss 222. When the first locking plate 1 and the second locking plate 2 are nested together, the central ridge 14 and the partition groove 24 are nested together. For larger document holders, the central ridge 14 acts as a reinforcing rib, enhancing the product's strength. Simultaneously, the nesting of the central ridge 14 and the partition groove 24 further enhances the stability of the nested arrangement of the first locking plate 1 and the second locking plate 2.

[0033] In use, documents, cards, etc. are placed in the first space 101 and / or the second space 102, and then the first card plate 1 and the second card plate 2 are nested together, using the first protrusion 221 and the second protrusion 222 to press and limit the documents and cards.

[0034] See Figure 5 As shown, this is Embodiment 2 of the present invention. The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 does not include the central protrusion 14 and the spacer groove 24. Embodiment 2 is designed for smaller document card holders. The other structural features of Embodiment 2 are the same as those of Embodiment 1, and will not be described again here.

[0035] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
