Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to an extendable combination card holder. Background Art

[0002] When items need to be stored according to function or personnel, modular card racks are a good solution. One type of modular card rack combines two adjacent boxes by setting a connecting structure between their front and rear walls, creating a slanted, chain-like structure. Items can be placed inside the boxes through their exposed top openings. This type of modular card rack allows for a vertical increase in the number of boxes, thus meeting more partitioning needs, and the exposed top openings also provide convenient access.

[0003] However, since the boxes in this type of card holder are arranged at an angle, the load-bearing parts inside are the bottom and front walls. When the bottom and front walls are under stress, the combined structure between the front and rear walls of two adjacent boxes will also be under stress to varying degrees. In scenarios where a large number of boxes need to be installed, it is necessary to ensure the overall reliability of multiple boxes, especially the stability of the upper box structure. When there is a combination deviation in the overall chain-like structure, the upper box is more likely to deform under excessive load due to abnormal assembly, which will lead to difficulties in subsequent disassembly and assembly. Summary of the Invention

[0004] The purpose of this utility model is to provide an extendable combination card holder, which can form a multi-layer box body obliquely arranged chain-like structure by combining with each other through sliding grooves and sliders, which facilitates the partitioned storage of items. It is not only structurally stable, but also makes it easy to judge whether the assembled chain-like structure is accurately and reliably combined.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] An extendable modular card holder includes at least two boxes that can be combined with each other. Each box has an upper opening on its upper side. The left and right side walls of the boxes are provided with straight box grooves extending to the upper part of the boxes. A connecting piece is provided on the inner side of the end of the straight box groove, and a side opening is provided on the outer side of the end of the straight box groove. The connecting piece and the straight box groove wall are correspondingly enclosed to form an end cavity. The left and right side walls of the boxes are provided with straight box strips extending from the lower part of the boxes to the middle part of the boxes. The outer edge of the end of the straight box strip is provided with an upward-facing box insertion post. The straight box strip of the rear box slides along the straight box groove of the front box to the end to form a combined and fixed state. The box insertion post of the rear box is correspondingly inserted into the end cavity of the front box, and the box insertion post is visible in the side opening.

[0007] Furthermore, a rear opening is provided on the rear side of the box.

[0008] Furthermore, a rear assembly plate is provided, which can be detachably combined with the bottom wall and / or side wall of the box body. The rear assembly plate partially or completely closes the rear opening, and the rear assembly plate does not interfere with the straight box body slide groove.

[0009] Furthermore, the rear assembly plate is in the shape of a folded plate, and the bottom wall of the rear assembly plate is engaged with the bottom wall of the box body through a snap-fit ​​part.

[0010] Furthermore, the engaging part consists of an elastic buckle disposed on the bottom wall of the rear assembly plate and a buckle fixing hole disposed on the bottom wall of the box body.

[0011] Furthermore, a base is provided, with straight base slides on the left and right side front edges of the base. An upward-facing box insertion post is provided on the outer edge of the end of the straight base slide. The straight box slide of the base slides along the straight box slide groove to the end to form a combined and fixed state. The base insertion post is inserted into the end cavity and is visible in the side opening. A hanging part is provided on the rear wall of the base.

[0012] Furthermore, the angle between the front wall and the rear wall of the base is 30°-60°, and the length of the straight base slide bar is one-third to two-thirds of the height of the left and right side walls of the base.

[0013] Furthermore, the left and right side walls of the box are also provided with a left clamping rail and / or a right clamping rail, with the left display panel fixed to the left clamping rail via the left clamping part and / or the right display panel fixed to the right clamping rail via the right clamping part.

[0014] Furthermore, a recessed area is provided along the upper edge of the front wall of the box.

[0015] Furthermore, the length of the straight box body slide bar is one-third to two-thirds of the height of the left and right side walls of the box body, and the length of the straight box body slide groove is not less than one-third of the height of the left and right side walls of the box body.

[0016] This utility model has at least the following advantages:

[0017] 1. The structure of the box insertion post and the end cavity set in this embodiment allows the box insertion post to be observed in place through the side opening after the slide rail is assembled. When the user can see the box insertion post and the base insertion post fully visible through the side opening, the overall assembly of the card holder is good. At this time, the box insertion post, the base insertion post and the connecting piece form a snap-fit ​​structure, thereby preventing the front box from expanding outward in the left and right directions and falling off from the rear box and base.

[0018] 2. The lengths of the straight box body slide strip and the straight base slide strip are reasonably set so that they can be inserted and matched with the straight box body slide groove to form a longer slide groove slide strip combination structure. This can provide sufficient assembly space between the front box body and the rear box body, and the combination card holder as a whole can form a stable combination structure.

[0019] 3. By adding left and right clamping rails, and combining them with a clamping mechanism that fixes the clamps to the rails, users can classify and determine the contents of the box based on the information provided by the left and right display panels. The left and right display panels are easy to pick up and put down, and can be quickly replaced as needed. Attached Figure Description

[0027] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] like Figure 1-7 As shown, an extendable combination card holder includes a base 2 and at least two modularly combinable housings 1, wherein:

[0030] The box body 1 has an upper opening on the upper side and a rear opening 104 on the rear side. The left and right side walls of the box body 1 are provided with straight box body grooves 11 extending from the lower part of the box body 1 to the upper part of the box body 1. A connecting piece 111 is provided on the inner side of the end of the straight box body groove 11, and a side opening 112 is provided on the outer side of the end of the straight box body groove 11. The connecting piece 111 and the wall of the straight box body groove 11 are correspondingly enclosed to form an end cavity. The left and right side walls of the box body 1 are provided with straight box body slides 12 extending from the lower part of the box body 1 to the middle part of the box body 1. The outer edge of the end of the straight box body slides 12 is provided with an upward-facing box body insertion post 121. The straight box body slides 12 of the rear box body 1 slides along the straight box body groove 11 of the front box body 1 to the end to form a combined and fixed state. The box body insertion post 121 of the rear box body 1 is correspondingly inserted into the end cavity of the front box body 1, and the box body insertion post 121 is visible in the side opening 112.

[0031] This embodiment, by providing a rear opening 104 on the rear side of the box body 1, compared to a solution that provides a rear sidewall on the rear side of the box body 1, utilizes the adjacent rear box body 1 or base 2 to close the rear opening 104, preventing the contents of the internal space from leaking out. This effectively saves product materials; however, if... Figure 1-2 As shown, since the rear box 1 or base 2 is obliquely combined with the front box 1 after assembly, the rear box 1 or base 2 cannot completely close the front box 1, forming an exposed rear opening 104. Therefore, this solution is more suitable for placing larger items, such as books, newspapers, and documents. In order to enable the combined card holder to hold smaller items and prevent such items from falling from the unclosed part, the exposed rear opening 104 can be closed by adding a rear combination plate 3. In this embodiment, an elastic buckle 31 is provided on the bottom wall 32 of the rear combination plate, which is shaped like a folded plate, and a buckle fixing hole 1031 is provided on the bottom wall 103 of the box. By combining the elastic buckle 31 and the buckle fixing hole 1031 to form a separable and combinable engagement part, the rear wall 33 of the rear combination plate closes the lower part of the rear opening 104 of the front box 1, and the rear combination plate 3 does not interfere with the straight box slide groove 11.

[0032] With this configuration, the rear box 1 or base 2 can be combined with the front box 1, and the exposed rear opening 104 can be partially or completely closed by the rear wall 33 of the rear combination plate, so that small items can be contained in the internal space enclosed by the front wall of the rear box, the left side wall and the right side wall of the front box, the bottom wall 32 of the rear combination plate, and the rear wall 33 of the rear combination plate.

[0033] By hanging or fixing the top box 1 or each box 1 to the wall, a chain-like structure can be formed between the combined card holder and the wall, allowing users to categorize and place items into the internal spaces of each box 1 from top to bottom. Of course, to facilitate the assembly and disassembly of each box 1, this embodiment also includes a base 2. The rear wall of the base 2 has a hanging part 20, which can be hung on a fixing nail to the wall, thus providing a fixed foundation for the other boxes 1. Specifically:

[0034] The left and right side walls of the base 2 are provided with straight base slides 12. The outer edge of the end of the straight base slide 12 is provided with an upward-facing box insertion post 121. The straight box slide 12 of the base 2 slides along the straight box slide groove 11 of the box 1 to the end to form a combined and fixed state. The base insertion post 221 is inserted into the end cavity and the base insertion post 221 is exposed in the side opening 112. The rear wall of the base 2 is provided with a hanging part 20.

[0035] In this example, the included angle α between the front wall and the rear wall of the base 2 is set to 35°, and the length of the straight base slide bar 12 is half the height of the left and right side walls of the base 2. With this setting, the tilt angle of each box 1 at the lower end of the base 2 forms a tilt angle of 35°. By reasonably setting the size of the included angle α, the user can conveniently take out, put in, and observe items from the opening of each tilted box 1. Moreover, the reasonable size of the included angle α also enables each box 1 to effectively hold items and prevent items from falling accidentally.

[0036] To facilitate users in determining the classification of box 1, in this embodiment, a left clamping rail 131 and a right clamping rail 132 are provided on the left and right side walls of box 1, respectively. The left display panel 41 is fixed to the left clamping rail 131 via the left clamping part 411, and the right display panel 42 is fixed to the right clamping rail 132 via the right clamping part 421. With this arrangement, users can determine the classification of items contained in box 1 based on the information provided by the left display panel 41 and the right display panel 42. Furthermore, the left display panel 41 and the right display panel 42 are easy to remove and place, and can be quickly replaced according to usage needs.

[0037] Preferably, in this embodiment, a recessed position 1011 is provided on the upper edge of the front wall of the box body 1. With this arrangement, when the internal space of the box body 1 contains flat items such as books and periodicals, the lower limit position can provide a larger display area for the items, making it easier to observe the items.

[0038] In this embodiment, the length of the straight box slide 12 is approximately half the height of the left and right side walls of the box 1, the length of the straight base slide 12 is approximately half the height of the left and right side walls of the base 2, and the length of the straight box groove 11 is close to the height of the left and right side walls of the box 1. With this arrangement, the straight box slide 12 has sufficient length to interlock with the straight box groove 11 extending from the lower part of the box 1 to the upper top of the box 1, forming a relatively long groove-slide combination structure. This provides sufficient assembly space between the front box 1 and the rear box 1, allowing the overall combination holder to form a stable assembly structure. Furthermore, to prevent the groove-slide structure from being incompletely assembled, or to avoid outward deformation of the front box 1 in the left and right directions due to aging, which could lead to dislocation of the straight box groove 11 of the front box 1, the straight box slide 12 of the rear box 1, and the straight base slide 12 of the base 2, this arrangement is designed to prevent dislocation of the straight box groove 11 of the front box 1, the straight box slide 12 of the rear box 1, and the straight base slide 12 of the base 2. In case the front box 1 accidentally falls off, the structure of the box insertion post 121 and the end cavity in this embodiment allows the box insertion post 121 to be observed through the side opening 112 after the slide rail is assembled. When the user can see the box insertion post 121 and the base insertion post 221 fully visible through the side opening 112, the overall assembly of the card holder is good. At this time, the box insertion post 121, the base insertion post 221 and the connecting piece 111 form a fastening structure, thereby preventing the front box 1 from expanding outward in the left and right directions and falling off from the rear box 1 and the base 2.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
