[0002] Cards are widely used in numerous fields, including games, collectibles, education, film, animation, and sports. To ensure card quality and improve ease of use, a variety of card protection devices are available on the market, but each has its own shortcomings that need to be addressed.

[0003] Traditional card holders typically use a square, flat box design with an opening at one end for holding the card. However, this design has significant drawbacks: firstly, cards are easily shaken and fall out of the box due to the lack of a stable holding structure; secondly, the material of the holder is usually not hard enough, providing only basic dirt protection and failing to effectively protect the card from external impacts. Some card users have turned to card sleeves similar to those used for public transport cards, but these sleeves are cumbersome to use, and after repeated use, the connecting parts are prone to wear and tear, affecting their lifespan and reliability. Additionally, there is the method of sealing cards with a protective film, but this method is difficult to implement, requires certain skills and tools, and once sealed, it is difficult to reopen, making it a disposable consumable that increases usage costs and causes environmental pollution.

[0004] In conclusion, existing card protection devices have significant room for improvement in terms of preventing cards from falling, providing effective protection, facilitating access, and being environmentally friendly and reusable, making it difficult to meet users' diverse needs for card protection and use.

Detailed Implementation

[0022] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0023] Please see Figures 1 to 4 The present invention discloses a card protective shell, including a carrier plate 10, a cover plate 20, an outer shell 30, and a connecting component.

[0024] like Figure 2 As shown, a shallow groove 101 is provided on the front side of the carrier plate 10, and a deep groove 102 is provided on the rear side of the shallow groove 101. The deep groove 102 is used to accommodate the card. Since the cards are mostly rectangular, the carrier plate 10, the shallow groove 101, and the deep groove 102 are all set as rectangular structures. The cover plate 20 is fastened to the shallow groove 101 and the card 40 is clamped in the deep groove 102. Specifically, the shallow groove 101 and the deep groove 102 adopt a stepped structure. The card 40 is clamped in the space enclosed by the cover plate 20 and the carrier plate 10, so that the card 40 is doubly limited in the vertical direction. This ensures the longitudinal positioning of the card in the deep groove 102 and the lateral constraint of the cover plate 20 is achieved through the shallow groove 101, forming a three-dimensional clamping space, which effectively prevents the card from shifting or tilting.

[0025] like Figure 2 and Figure 3 As shown, the outer shell 30 has a receiving cavity 31, the upper end of which is an open end. The connecting assembly includes an upper magnet 104 and a lower magnet 32. The upper magnet 104 is disposed on the outer bottom surface of the carrier plate 10, and the lower magnet 32 ​​is disposed on the inner bottom surface of the receiving cavity 31. The upper magnet 104 and the lower magnet 32 ​​are magnetically connected to fix the carrier plate 10 and the cover plate 20 in the receiving cavity 31. The carrier plate 10 and the cover plate 20 both have transparent parts for displaying cards, and the front and rear side walls of the outer shell 30 have card display holes.

[0026] Specifically, the carrier plate 10 and the cover plate 20 are made of polystyrene or plexiglass, so both the carrier plate 10 and the cover plate 20 are transparent. The outer shell 30 is made of polystyrene, plexiglass or PC. The shape of the display hole is consistent with the shape of the card, and the size of the display hole is slightly larger than the size of the card. This ensures that the pattern on the card 40 is fully displayed, while avoiding card deformation caused by edge squeezing.

[0027] like Figure 2 and Figure 3As shown, the bottom sidewall of the shallow groove 101 has a slot 103, and the bottom sidewall of the cover plate 20 has an insert 21. The slot 103 and the insert 21 are interference-fitted to form a first snap-fit ​​connection between the cover plate 20 and the carrier plate 10. Preferably, there are two slots 103 spaced apart, and the insert 21 is fitted to each slot 103 one by one. The slot 103 is a square groove, and the insert 21 is a square block with rounded corners. The left and right sidewalls of the cover plate 20 are clearance-fitted with the left and right sidewalls of the shallow groove 101 or are fitted together. The interference fit structure of the slot 103 and the insert 21 provides a mechanical interlocking force of 0.3-0.5mm, forming the first physical lock. The combination design of the two spaced square slots and the rounded square inserts ensures the connection strength while achieving the guiding and positioning function, ensuring the accurate repositioning of the cover plate 20.

[0028] In this embodiment of the invention, a front magnet 22 is embedded in the upper part of the rear side of the cover plate 20, and a rear magnet 105 is embedded in the upper part of the front side of the carrier plate 10. The front magnet 22 and the rear magnet 105 magnetically attract each other, forming a second magnetic connection between the cover plate 20 and the outer shell 30. Specifically, the upper part of the rear side of the cover plate 20 has a first mounting hole, in which the front magnet 22 is installed. The upper part of the front side of the carrier plate 10 has a second mounting hole, in which the rear magnet 105 is installed. The surface magnetic attraction structure of the front magnet 22 and the rear magnet 105 provides an additional attraction force of 1.5-2N in the vertical direction, forming a second locking defense. This double locking structure allows the cover plate 20 to remain closed even when subjected to accidental impact, effectively preventing the card from accidentally falling off.

[0029] In an embodiment of this utility model, a prying-opening assist groove 23 is provided at the upper middle part of the rear side of the cover plate 20. The prying-opening assist groove 23 makes the opening operation of the cover plate 20 easy and effortless, and further facilitates the replacement of the card 40.

[0030] In an embodiment of this utility model, the upper end of the receiving cavity 31 extends to the upper ends of both sides of the outer shell 30 to form a side opening 33. The upper ends of both sides of the carrier plate 10 are provided with side protrusions 106 that are inserted and matched with the side openings 33. The side protrusions 106 opposite to the receiving cavity 31 are provided with a pushing assist part 107 protruding from the side wall of the outer shell 30. The pushing assist part 107 has a sloping structure. The pushing assist part 107 facilitates the quick removal of the carrier plate 10 together with the cover plate 20 from the outer shell 30, thereby further improving the convenience of changing cards.

[0031] In the embodiments of this utility model, the front and rear side walls of the carrier plate 10 are provided with clamping ribs 108, and there are four clamping ribs 108. Two clamping ribs 108 are provided at the bottom of the front and rear side walls of the carrier plate 10. The clamping ribs 108 help to increase the resistance between the carrier plate 10 and the housing 30, and effectively prevent the carrier plate 10 from shaking.

[0032] This utility model discloses a card protective case that ensures a tight connection between the cover plate and the carrier plate through the interference fit of the slot and the insertion block, as well as the attraction between the front and rear magnets. This effectively prevents the cards from loosening or falling off during use. The design of the pry-opening assist groove and the pushing assist part makes card replacement simpler and faster, improving the user experience. The use of reusable materials and structural design reduces the use of disposable consumables, lowers environmental pollution, and improves the durability of the card protective case.
