Description

Technical Field

[0001] This utility model relates to the field of card box technology, and in particular to a card box with a simple structure, convenient for storing and retrieving cards, and easy to carry. Background Technology

[0002] As the market for metal card holders has grown over time, users have become increasingly demanding in terms of product details. With the prevalence of online cash payments, people are carrying less cash and no longer need the ability to carry large amounts of cash. This has led to a greater preference for compact and portable wallets and card holders. Current metal card holders are used to store bank cards, business cards, receipts, and other similar cards.

[0003] Modern life involves dealing with cards to varying degrees, such as bank cards, supermarket cards, shopping cards, and membership cards. If these cards are not stored properly, they can easily become damaged, leading to unnecessary trouble. Card boxes are a product of the modern economy, designed to hold these cards. Card boxes generally come in two forms: flip-style, like book pages, and rotating styles. In terms of material, leather is the most common, as it is lightweight and portable, similar to a wallet.

[0004] When there are multiple cards in the card holder, inserting and retrieving cards becomes inconvenient. Furthermore, when carrying the card holder, cards are prone to falling out or breaking during bumpy journeys, causing unnecessary trouble. In addition, protecting cards from breakage and providing convenient storage and retrieval of cards have become basic needs for users. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the above-mentioned technology and provide a simple, easy-to-operate and carry card box to meet the different needs of users.

[0006] The technical problem of this utility model is solved by the following technical solution: A card box is provided for holding multiple cards, comprising a shell and a fixed frame fixedly installed within the shell; the card box further includes an elastic pressing device, an elastic element, and a sliding element; the elastic pressing device is mounted on the fixed frame and located at the card insertion slot, and is used to press against the side of the card; the sliding element is connected to the fixed frame through the elastic element and slides on the fixed frame; a guide rod is provided on the fixed frame, and one end of the guide rod is fixed. On the fixed frame, with one end being a free end; the sliding member is provided with a guide groove, and the up and down sliding of the sliding member causes the guide groove to limit the free end of the guide rod to move relative to the guide rod within the guide groove. When the free end of the guide rod is engaged with the positioning part of the guide groove, after releasing the pressed card, the multiple cards are positioned in the card box; when the top of the multiple cards is pressed again, the free end of the guide rod disengages from the positioning part of the guide groove, and the elastic member pulls the sliding member upward to the initial position, thereby pushing the multiple cards out of the card box.

[0007] As a further improvement of this application, the elastic pressing device includes a pressing block for pressing against the side of the card and a spring mounted on the pressing block, wherein the side of the card presses against the pressing block to move outward and compress the spring.

[0008] As a further improvement of this application, a mounting block is provided on each side of the card insertion port of the outer shell, and two screws pass through the mounting blocks to fix the pressing block on the fixing frame.

[0009] As a further improvement of this application, the fixing frame includes a crossbeam at the bottom and a left beam and a right beam on both sides of the crossbeam. The inner side of the crossbeam is provided with two receiving parts, each receiving part receiving one end of a stop block. The stop block is equipped with a small spring, and the other end of the stop block abuts against the bottom side of the card.

[0010] As a further improvement of this application, one end of the guide rod is fixed to the right side beam, and a limiting piece protrudes horizontally outward on the right side beam, the limiting piece blocking the elastic deformation of the guide rod in the vertical direction.

[0011] As a further improvement of this application, the sliding member includes a crossbar located at the bottom and a left bar and a right bar located on both sides of the crossbar, and the crossbar is also provided with a movable block that moves up and down.

[0012] As a further improvement of this application, the crossbar is provided with multiple steps, the vertical sides of the multiple steps abutting against the bottom sides of multiple cards respectively, thereby initially positioning the multiple cards; the movable block is also provided with multiple steps, the vertical sides of the multiple steps abutting against the bottom sides of other cards respectively, thereby initially positioning the other cards.

[0013] As a further improvement to this application, the height of two adjacent steps is less than or equal to the thickness of each card.

[0014] As a further improvement of this application, a blocking block is provided on the right-side rod to prevent the guide rod from moving back.

[0015] As a further improvement to this application, the elastic element is an elastic band or elastic strip.

[0016] The beneficial effects of this utility model are as follows: By pressing the card downwards, the card presses down against the sliding member connected to the elastic element, causing the guide rod to move by the guide groove of the sliding member, thereby hooking the positioning part of the guide groove and positioning the sliding member. The cards are then pressed against the horizontal pressing block and the vertical abutting block, thus positioning them inside the card holder. To remove the cards, the user only needs to slightly press the top of the card with their thumb. The guide rod disengages from the positioning part of the guide groove, and the sliding member is pulled upwards and returns to its initial position under the elastic restoring force of the elastic element, allowing the cards to be pushed out for easy removal of any card. This utility model's card holder has a simple structure, is convenient for inserting and removing cards, and can be operated with one hand, making it easy to use. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] For reference Figures 1 to 8 As shown, this utility model provides an embodiment of a card box, which is a simple card box 100 that conveniently accommodates multiple cards 200. It includes a shell 10 made of aluminum alloy and a fixed frame 20 made of plastic, which is fixedly mounted inside the shell 10 by multiple screws 18. Each end of the card insertion slot on the fixed frame 20 is provided with an elastic pressing device 30. One end of the fixed frame 20 is connected to a sliding member 50 via two elastic members 40. The sliding member 50 carries multiple cards 200 and moves up and down along the inside of the fixed frame 20. In this embodiment, the number of cards 200 is six. It can be understood that, as needed, the card box 100 can be designed to store more than six or less cards.

[0042] At each end of the card insertion port of the outer casing 10, there is a mounting block 12. Each screw 18 passes through each mounting block 12 to fix each elastic pressing device 30 to both ends of the card insertion port, thereby ensuring that the card 200 can be easily inserted and that the card 200 is positioned after insertion so that it will not easily fall out. Two other screws 18 pass through the screw holes of the outer casing 10 to fix the fixing frame 20 to the inside of the outer casing.

[0043] The fixing frame 20 is U-shaped, including a crossbeam 21 at the bottom and a left beam 22 and a right beam 23 on either side of the crossbeam 21. A long, narrow guide rod 24 made of metal is provided on the right beam 23 at its intersection with the crossbeam 21. One end of the guide rod 24 is fixed to the right beam 23, and the other end is an L-shaped free end. A limiting piece 231 protrudes horizontally outward from the right beam 23 (see...). Figure 8 The limiting piece 231 restricts the vertical (up-down) swing of the guide rod 24, thus minimizing the elastic deformation of the guide rod 24 in the vertical direction, while allowing it to swing left and right without obstruction of its elastic deformation in the left-right direction. A positioning post 233 is also provided on the right beam 23 for positioning one end of an elastic element 40, with the other end of the elastic element 40 fixed to the sliding member 50. A positioning post 223 is also provided on the left beam 22 for positioning one end of another elastic element 40, with the other end of the other elastic element 40 also fixed to the sliding member 50. In this embodiment, the elastic element 40 is a large spring, but it could also be an elastic band or elastic strip, or other elastic element. After installation, the bottom outer side of the crossbeam 21 is flush with the bottom outer side of the outer casing 10, perfectly sealing the opening in the outer casing 10, thereby forming the bottom of the card box 10. The inner side of the crossbeam 21 is provided with two receiving portions 25, each receiving portion 25 receiving one end of a stop block 26. A small spring 261 is installed inside the stop block 26, with one end of the small spring 261 fitted onto a protrusion inside the receiving portion 25 of the crossbeam 21, and the other end of the small spring 261 positioned inside the stop block 26. This allows one end of the stop block 26 to move elastically within the receiving portion 25, while the other end of the stop block 26 passes through the crossbar 51 of the sliding member 50 to elastically abut against multiple cards 200. The left beam 22 and right beam 23 are respectively equipped with elastic pressing devices 30 at the card insertion inlets. Each elastic pressing device 30 includes a pressing block 31 and a small spring 32 mounted on the pressing block 31. The restoring force of the small spring 32 allows the pressing block 31 to move elastically, simultaneously pressing against the side of the card 200. The pressing block 31 has an arc surface on its inner side. After the card 200 is completely fixed, the arc surface of each pressing block 31 presses against the arc surface on one side of the end of the card 200, thereby locking the card 200 so that the card 200 does not fall off.

[0044] The sliding member 50 is movably mounted inside the fixed frame 20. The sliding member 50 is approximately U-shaped, comprising a crossbar 51 at its bottom and a left bar 52 and a right bar 53 located on either side of the crossbar 51. The crossbar 51 is also provided with a movable block 54 that can move up and down within a certain range. Two protrusions 547 of the movable block 54 move within two grooves 517 on one side of the crossbar 51 (see...). Figure 4This reduces the distance between the bottom of the first card and the bottom of the sixth card, decreasing the longitudinal dimension of the card holder 100 and making it even smaller for easier carrying. One end of the left rod 52 and the right rod 53 is provided with positioning posts 521 and 531, respectively. The other ends of the two elastic members 40 are fixed to the positioning posts 521 and 531, respectively, thus limiting the sliding member 50 to the fixed frame 20 and allowing it to move elastically within a certain distance. Furthermore, the right rod 53 is provided with a guide groove 533 for the guide rod 24 to move within it. The top of the guide groove 533 is provided with a recessed positioning part 535, allowing the free end of the guide rod 24 to hook onto the positioning part 535, temporarily positioning the sliding member 50. Above the positioning part 535, the right rod 53 is provided with a blocking block 536 to prevent the guide rod 24 from moving backward. The crossbar 51 has four steps 511, 512, 513, and 514. The vertical sides of these four steps abut against the bottom sides of the four cards 200, thus initially positioning the four cards 200. The movable block 54 also has two steps 545 and 546. The vertical sides of these two steps 545 and 546 abut against the bottom sides of the fifth and sixth cards 200, thus initially positioning the fifth and sixth cards 200. It can be understood that, to facilitate the free movement of each card 200, the height of two adjacent steps is generally less than or equal to the thickness of each card.

[0045] During installation, the crossbar 51 of the slider 50 is installed between the left beam 22 and the right beam 23 of the fixed frame 20, and is positioned below the left beam 22 and the right beam 23. The left rod 52 and the right rod 53 of the slider 50 are correspondingly positioned outside the left beam 22 and the right beam 23 of the fixed frame 20. One end of one elastic member 40 is fixed to the positioning post 223 of the left beam 22, and the other end is fixed to the positioning post 521 of the left rod 52; one end of the other elastic member 40 is fixed to the positioning post 233 of the right beam 23, and the other end is fixed to the positioning post 531 of the right rod 53. In this way, the slider 50 is limited on the fixed frame 20. In the initial position (before the card is inserted), the slider 50 is supported by the protrusion 225 at the bottom of the fixed frame 20 (see...). Figure 16 and Figure 19The two elastic elements 40 are blocked, preventing the sliding member 50 from sliding upwards and allowing it to slide downwards. Furthermore, the two elastic elements 40 have undergone elastic deformation and possess a certain tensile force. When the sliding member 50 is pushed downwards, the two elastic elements 40 undergo further elastic deformation, and their tensile force causes the sliding member 50 to return to its initial position. Further, the pressing block 31 and a small spring 32 cooperating with the pressing block 31 are respectively installed at the upper ends of the left beam 22 and the right beam 23 (i.e., at the card insertion point). The small spring 32 allows the pressing block 31 to move elastically left and right, causing the pressing block 31 to press against the side of the card 200. The pressing block 31 has an arc surface on its inner side. After the card 200 is completely fixed, the arc surface of the protrusion 313 of each pressing block 31 presses against the arc surface on one side of the end of the card 200 (see...). Figure 8 This prevents the card 200 from falling off. When the card 200 is inserted, the two sides of the card 200 press against the protrusion 313 of the pressing block 31, causing the pressing block 31 to move outward and simultaneously press against the small spring 32.

[0046] Further reference Figures 9 to 17When the first card 200 is inserted, its two sides press against the protrusions 313 of the left and right end pressure blocks 31, causing the pressure blocks 31 to move outward and simultaneously compress the small spring 32. The first card 200 continues to be inserted until its bottom side abuts against the vertical side of the step 511 on the crossbar 51. When the second card 200 is inserted, since the two sides of the first card 200 have already pressed against the protrusions 313 of the left and right end pressure blocks 31, the two cards 200 pass smoothly through the pressure blocks 31 without obstruction. The second card 200 continues to be inserted until its bottom side abuts against the vertical side of the step 512 on the crossbar 51. When the third card 200 is inserted, since the two sides of the first card 200 have already pressed against the protrusions 313 of the left and right end pressure blocks 31, the three cards 200 pass smoothly through the pressure blocks 31 without obstruction. The third card 200 continues to be inserted until its bottom side abuts against the vertical side of the step 513 on the crossbar 51. When the fourth card 200 is inserted, since the two sides of the first card 200 have already pressed against the protrusions 313 of the left and right end pressure blocks 31, the four cards 200 pass smoothly through the pressure blocks 31 without obstruction. The fourth card 200 continues to be inserted until its bottom side abuts against the vertical side of the step 514 on the crossbar 51. When the fifth card 200 is inserted, since the sides of the first card 200 have already pressed against the protrusions 313 of the left and right end pressure blocks 31, the five cards 200 pass smoothly through the pressure blocks 31 without obstruction. The fifth card 200 continues to be inserted until its bottom side abuts against the vertical side of the step 545 on the movable block 54. When the sixth card 200 is inserted, since the sides of the first card 200 have already pressed against the protrusions 313 of the left and right end pressure blocks 31, the six cards 200 pass smoothly through the pressure blocks 31 without obstruction. The sixth card 200 continues to be inserted until its bottom side abuts against the vertical side of the step 546 on the movable block 54. Thus, the six cards 200 are initially positioned. To prevent the six cards 200 from slipping, they need to be further positioned. The user holds the card holder 100 with one hand and presses the first card 200 with his thumb. The bottom side of the first card 200 further abuts against the vertical side of the step 511 on the crossbar 51, causing the slider 50 to move downward. At the same time, each elastic element 40 is stretched to generate a greater restoring force.Simultaneously, the guide groove 533 of the slider 50 also moves downward. Since one end of the guide rod 24 is fixed and is limited in the vertical direction by the outwardly protruding limiting piece 231 on the right beam 23, the free end of the guide rod 24 can only swing in the horizontal direction (elastic deformation occurs in the left and right direction). The free end of the guide rod 24 enters the guide groove 533 and moves relative to it in the guide groove 533 (the guide groove 533 moves up and down, and the guide rod swings slightly left and right along the guide groove 533). Further pressing the first card 200 causes the bottom side of the first card 200 to further abut against the vertical side of the step 511 on the crossbar 51, causing the slider 50 to move further downward. At the same time, each elastic element 40 is stretched to generate a greater restoring force. Simultaneously, the guide groove 533 of the slider 50 moves further downward until the free end of the guide rod 24 enters the recessed positioning part 535 at the top of the guide groove 533 and hooks onto the positioning part 535, thereby temporarily positioning the slider 50. During this process, as the slider 50 moves further downward, a small spring 261 is installed at one end of the abutment block 26, allowing one end of the abutment block 26 to move elastically within the receiving part 25. The other end of the abutment block 26 passes through the crossbar 51 of the slider 50, thereby elastically pressing against the second to sixth cards 200. At this point, the first card 200 is released. The tops of the six cards 200 are flush, and both sides of the six cards 200 are pressed by the protrusions 313 of the pressing block 31. The bottoms of the six cards 200 are also flush, and the bottom sides of the second to sixth cards 200 press against the other end of the pressing block 26, thereby compressing the small spring 261. Finally, the cards 200 are elastically pressed in both the horizontal and vertical directions, thus being fixed in the final fixed position and not easily falling off.

[0047] Further reference Figures 18 to 21 When the user wants to remove card 200, firstly, the user holds the card holder 100 with one hand, and then presses the tops of the cards 200 slightly downwards with their thumb (all card tops are flush). The first card 200 presses down against the vertical side of the step 511 on the crossbar 51, causing the slider 50 to move further downwards. The bottoms of the second to sixth cards 200 press down against the end 263 of the abutment block 26, compressing the small spring 261, further compressing the small spring 261. At the same time, the free end of the guide rod 24 is abutted by the blocking block 536 that prevents the guide rod 24 from moving back as the slider 50 moves downwards, thus sliding towards the inner guide groove of the guide groove 533 (e.g., Figure 20 As shown), the direction of motion of the free end of the guide rod 24 is referenced. Figure 5 and Figure 7The arrow direction. At this time, releasing the pressure on the top of these cards 200, the slider 50 is pulled upward under the elastic restoring force of the elastic member 40, and the free end of the guide rod 24 returns to its initial position along the inner guide groove of the guide groove 533 (as shown in the arrow direction). Figure 9 (as shown in the position of the guide rod 24), so that the movement trajectory of the free end of the guide rod 24 forms a closed curve. As the slider 50 moves further upward until it is stopped by the protrusion 225 at the lower part of the fixed frame 20 (see...) Figure 19 and Figure 21 The six cards 200 are blocked and prevented from moving upwards. They are pushed back to their initial positions by the vertical sides of the six steps 511, 512, 513, 514, 545, and 546, respectively, so that the user can take out any card.

[0048] If the user presses the top of these cards 200 with considerable force until they stop moving downwards (i.e., when they can no longer be pressed down), during this process, the first card 200 further presses downwards against the vertical side of the step 511 on the crossbar 51, causing the slider 50 to move further downwards until the movable block 54 is fixed between the crossbar 51 and the beam 21. At this point, the protrusion 537 of the movable block 54 extends into the innermost part of the groove 517 of the crossbar 51 and presses against each other, and the elastic member 40 is stretched to its maximum position. In addition, the bottom of the second to sixth cards 200 further presses downwards against the end 263 of the abutment block 26, thereby further compressing the small spring 261. When the user feels that they can no longer press the cards 200 at the final position of the downward press, they should stop pressing the cards 200. Under the elastic restoring force of the elastic member 40, the slider 50 will move further upward until it is stopped by the protrusion 225 at the lower part of the fixing frame 20 (see...). Figure 19 and Figure 21 The six cards 200 are blocked and prevented from moving upwards. They are pushed back to their initial position by the vertical sides of the six steps 511, 512, 513, 514, 545, and 546, respectively, allowing the user to easily remove any card. Therefore, the user can make these cards pop out by pressing hard or lightly, allowing them to easily remove any card. This simple and effective operation makes it very convenient for users to retrieve cards and has won the favor of consumers.

[0049] This invention allows the card holder to be positioned by pressing down on the card, causing it to slide downwards against a sliding member connected to an elastic element. This causes the guide rod to move along the guide groove of the sliding member, hooking onto the positioning part of the guide groove and positioning the sliding member. The cards are then pressed against the horizontal pressing block 31 and the vertical abutting block 26, thus securing them within the card holder 100. To remove the cards, the user simply presses the top of the cards slightly with their thumb. The guide rod disengages from the positioning part of the guide groove, and the sliding member moves upwards and returns to its initial position under the elastic restoring force of the elastic element, allowing the cards to be pushed out for easy removal. This invention features a simple card holder structure, convenient card insertion and removal, and can be operated with one hand, making it easy to use.
