[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings:

[0035] A type of narrow-slit cabinet, such as Figures 1-14 As shown, the device is made of plastic for mass injection molding and leverages its plasticity to facilitate various snap-fit ​​connections, hinges, shaft connections, and interference fits. It is designed as a cuboid with a front and back, and long sides, including side plates 3 as the long sides, a frame 1 as the short sides, and a folding plate 2 as the rear. The folding plate 2 has the same side structure as the patent in CN222675741U. The two ends of the folding plate 2 are hinged to the side plates 3, and the middle hinge allows it to fold inwards. The frame 1 is inserted into the side plates 3. Multiple side plates 3, frames 1, and folding plates 2 can be inserted vertically. This system allows for the transformation from a single-layer to a multi-layer narrow-slit cabinet. The frame 1 is a one-piece molded rectangular rigid frame that, when inserted with the side panels 3, does not obstruct the front access to the interior of the cabinet. The frame 1 has four double-hole long slots 12 at its corners, extending rearwards to the outer side of the frame 1. Each slot includes a first limiting hole 121 and a second limiting hole 122 running front-to-back. The first and second limiting holes 121 are continuous, with a centrally protruding limiting wall 123 in the middle. Limiting posts 34 are located at the upper and lower ends of the front side of the side panels 3. When the frame 1 is inserted with the side panels 3, the limiting posts 34 are confined within the first limiting hole 121. Figure 11 As shown, after forcefully pushing the frame 1, the limiting post 34, under plastic action, passes through the limiting wall 123 and enters the second limiting hole 122, thus completing the insertion; when the frame 1 is disassembled from the side plate 3, it can be selected that both sides of the frame 1 are detached from the side plate 3 to form an independent placement state—that is, at this time, all the limiting posts 34 on both sides of the frame 1 are separated from the double-hole long pull groove 12; as Figure 12 As shown, alternatively, one side of the frame 1 can be detached from the side panel 3, while the limiting post 34 on the other side of the frame 1 remains within the second limiting position, allowing the frame 1 to rotate around this axis and be stored within the side panel 3. This method is preset at the factory, making it convenient for users to directly unfold and insert the components when assembling the product upon receipt, resulting in easy installation. Preferably, as... Figure 2 As shown, a strip hole 31 can be provided on the upper part of the side plate 3 to facilitate hand gripping when moving the narrow-slot box.

[0036] To facilitate the partitioning of the interior space of the narrow-slit cabinet, such as Figure 1 , Figure 2 and Figure 6As shown, a front-to-back shelf A32 is provided on the inner wall of the side panel 3. Multiple blocks A321 are provided at intervals on the shelf A32. Multiple blocks B33 are also provided on the inner wall of the side panel 3. The blocks B33 are located above the shelf A32. Multiple extension plates A41 are provided on the left and right edges of the shelf 4. A receiving groove A411 is provided between two extension plates A41. The shelf 4 rests on the shelf A32 to divide the narrow-slit cabinet into multiple spaces. The extension plates A41 abut against the blocks A321 on the side and against the blocks B33 on the top, so that the shelf 4 cannot move back and forth or up and down. Depending on the different positions of the shelf A32 on the inner wall of the side panel 3 (top, middle, and bottom), the multiple shelves 4 can flexibly serve as the top, middle, and bottom plates of the narrow-slit cabinet. Multiple shelves A32 can be set on a side panel 3 with the same or different intervals as needed. In this way, only shelves 4 with the same structure are needed to achieve the functions of middle partition and top and bottom closure at the same time. Preferably, the stop block B33 includes a stop block inclined surface 331 and a stop block flat surface 332. The stop block inclined surface 331 is inclined downward, which makes it easier for the shelf 4 to undergo plastic deformation during installation, making it easier for the extension plate A41 to slide over the stop block inclined surface 331 and abut against the stop block flat surface 332 for limitation. After the shelf 4 is connected to the side plates 3 on the left and right sides, it can realize the storage or closure function. In order to make the shelf 4 stronger and further enhance the stability of the narrow gap cabinet, multiple extension plates B42 are provided on the front and rear edges of the shelf 4. A receiving groove B421 is set between two extension plates B42. The inner side of the folding plate 2 is provided with a longitudinal reinforcing rib 21 and a transversely arranged shelf bar B22 at the same level as the shelf bar A32. The front and rear ends of the shelf 4 rest on the shelf bar B22, and the extension plate B42 abuts against the reinforcing rib 21 on the side. In this way, the left, right and rear sides of the shelf 4 are connected to the inner side of the narrow gap cabinet.

[0037] Based on this, in addition to the functional role of shelf 4 as the top panel of the narrow-slit cabinet, considering aesthetics, such as Figure 5 , Figure 13 and Figure 14 As shown, a top cover 5 can be further provided, which can be detachably inserted into the upper end of the topmost side panel 3, frame 1, and folding plate 3.

[0038] The connection between the frame 1 and the side panel 3, the connection between multiple side panels 3, the frame 1, and the folding panels 2, and the connection between the top cover 5 and the uppermost side panel 3, frame 1, and folding panel 3 are all achieved using the insertion assembly 8. Taking the connection between two adjacent folding panels 3 as an example, Figure 5 As shown, the plug-in assembly 8 includes a protruding plug-in block 81 and a recessed plug-in groove 82. A limiting groove 811 is provided on the side of the plug-in block 81, and a limiting block 821 is provided on the side of the plug-in groove 82. During plug-in, the plug-in block 81 is inserted into the groove 82. During this process, the limiting block 821, under the action of plastic deformation, enters the limiting groove 811 and then returns to its original shape to form a limiting position.

[0039] like Figure 3 and Figure 8 As shown, a locking assembly 10 is provided between the top cover 5 and the side plate 3, and between the upper and lower adjacent side plates 3 to achieve mutual fastening. The locking assembly 10 includes a fastener 101 that can rotate up and down, and the fastener 101 is provided with a cavity 1011 for hand operation. It also includes a lock 102, which is set as an L-shaped limiting member 103. The fastener 101 is provided with an L-shaped limiting member 103 that is symmetrical with the locking member 102. The two L-shaped limiting members 103 can form or release the engagement under the action of external force based on the plastic deformation property. Taking the fastening between the top cover 5 and the side plate 3 as an example, the lower end of the fastener 101 is connected to the top side of the side plate 3, and the upper end is provided with an L-shaped limiting member 103. The locking member 102 is also an L-shaped limiting member 103. The same vertical side of the two centrally symmetrical L-shaped limiting members 103 moves towards each other and touches each other. As the opposing movements continue, plastic deformation occurs until they cross each other. After the plastic deformation is restored, a limit lock is formed without external force. By holding the cavity 1011 and pulling the fastener 101 to rotate the opposite axis, the lock can be released in the same way.

[0040] like Figure 14 As shown, in one embodiment, in order to achieve the closure of the narrow-slit cabinet, a door panel 6 can be installed on the frame 1. One side of the door panel 6 is axially connected to the frame 1. The door panel 6 is also provided with a handle A62. Pulling the handle A can realize the opening and closing of the door panel 6 and the frame 1. Preferably, the door panel 6 and the frame 1 are connected when closed by a magnet on the side that is open or closed.

[0041] like Figure 13 As shown, in another embodiment, to achieve the closure of the narrow-slit cabinet, a pull-out mechanism is used, with drawers 20 provided. One or more drawers 20 can be provided inside the frame 1 as needed. Specifically, the drawer 20 includes a main body 201 that can move back and forth on the shelf 4 and a front cover 202 on the front side of the main body 201. The front cover 202 is provided with a handle B2021 that can be pulled by hand. The handle B2021 and the front cover 202, as well as the front cover 202 and the main body 201, are connected by a detachable structure, preferably a snap-fit ​​structure, to facilitate injection molding demolding and production. The main body 201 can be stored inside the narrow-slit cabinet. One or more front covers 202 can cover the frame 1 to achieve the closure of the narrow-slit cabinet. That is, drawers 20 of different heights can correspond to shelves 4 with different distances to accommodate the different heights of the shelves 4. In this embodiment, to reduce the friction between the bottom surface of the main body 201 and the upper surface of the shelf 4 and facilitate pushing and pulling, such as Figure 7 , Figure 9 and Figure 10As shown, a track ridge 2011 can be provided on the bottom surface of the main body 201, and a track groove 43 with a front-to-back orientation can be provided on the upper surface of the shelf 4. The track ridge 2011 is accommodated in the track groove 43, allowing the drawer 20 to move along the track. Furthermore, roller mounting portions 2012 can be provided on the left and right sides of the rear end of the bottom surface of the main body 201. The roller mounting portions 2012 can engage one side of the roller to further reduce friction. In this embodiment, the drawer 20 is used to store items, while the shelf 4 mainly serves a supporting function. Figure 7 As shown, shelf 4 can be configured as a hollow structure to save materials and reduce costs.

[0042] As can be seen from the above description, the above embodiments achieve the following technical effects: the rigid frame and the limiting of the shelves by the blocks A and B enhance the stability of the narrow-slit cabinet. At the same time, the same shelf structure can be flexibly used as a top plate, bottom plate and partition plate, reducing the number of parts and lowering mold and production costs.

[0043] The above description is merely an exemplary embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The scope of protection of the present utility model is determined by the appended claims.
