Description

Technical Field

[0001] This utility model relates to the field of furniture panel structure technology, and more specifically, to a panel connection structure and a shelf including the panel connection structure. Background Technology

[0002] Shelves, as a common storage structure, provide a stable load-bearing surface for placing items; they are widely used in display and storage scenarios. However, existing shelves typically use the most basic form, with a flat surface and no obstructions on the sides. When items placed on them are subjected to slight external forces, or when the shelves are placed in environments prone to vibration or impact, items can easily slip off the edges, causing damage, posing safety hazards, and resulting in a poor user experience.

[0003] To address the issue of items falling off shelves, a common improvement is to add guards around the perimeter of the shelf. However, this solution introduces a significant manufacturing defect: the guards are not tightly bonded to the shelf body, resulting in noticeable seams. Due to limitations in machining precision, assembly errors, or connection structures, the seams at the connection point are prone to being too large, leading to rough manufacturing processes and reduced product quality.

[0004] Therefore, there is an urgent need in this field for an innovative plate connection structure that can achieve tight connections and improve the process quality of products. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings and deficiencies in the prior art and provide a plate connection structure and a shelf including the plate connection structure; the plate connection structure can make the main plate and the auxiliary plate tightly connected to ensure a firm connection, reduce the width of the joint between the two, facilitate position alignment and fixation during assembly, and improve the process quality.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a plate connection structure, including a main plate and an auxiliary plate; the side of the main plate near the auxiliary plate extends outward to form a thin edge; the auxiliary plate has a slot; the thin edge is engaged in the slot of the auxiliary plate; the thin edge and the slot wall are positioned against each other through a concave-convex structure, and a locking element is provided in the concave-convex structure to fix the thin edge and the slot wall together.

[0007] This invention utilizes a thin edge and slot to achieve a mating connection between the main board and the auxiliary board, increasing the contact area between them and ensuring a tight and secure connection. It effectively reduces the visual thickness at the connection point, eliminating the bulky and rigid feel of traditional thick plate connections. Furthermore, it reduces the width of the joint, improving process quality. The use of a concave-convex structure and locking elements within it allows for mutual positioning and fixation of the main board and auxiliary board, facilitating alignment and fixation during assembly and improving product quality.

[0008] Preferably, the concave-convex structure includes: a positioning opening on the outer side of the thin edge, and a positioning block disposed inside the slot; the number of positioning openings and positioning blocks are matched, and their positions correspond; the locking element is disposed in the positioning opening and the positioning block. The positioning opening and the positioning block can effectively realize the mutual positioning of the main board and the auxiliary board.

[0009] Preferably, the locking element refers to a positioning pin; the inner wall of the positioning port and the positioning block are respectively provided with mounting holes for inserting the positioning pin. The inner wall of the positioning port and the positioning block provide mounting space for the positioning pin, allowing the positioning pin to be hidden inside the main board and auxiliary board, further improving product quality. The positioning pin can effectively fix the main board and auxiliary board to each other.

[0010] Preferably, there are two or more positioning ports and positioning blocks.

[0011] Preferably, the thin edge and the main board are an integral structure; the auxiliary board and the positioning block are an integral structure.

[0013] A shelf panel includes a main board and an auxiliary board; the auxiliary board is positioned on one or both sides of the main board; the main board and the auxiliary board are connected by the aforementioned board connection structure.

[0014] The aforementioned shelf, with auxiliary panels positioned on one or more sides of the main board (such as the front, back, left, and right sides), prevents items placed on the main board from falling and improves storage safety. The structure also ensures the shelf has good mechanical strength and high product quality.

[0015] Preferably, the auxiliary plates are positioned above and on both sides of the main plate; adjacent auxiliary plates are joined together; of the two joined auxiliary plates, one auxiliary plate has a first joining slope and a thin edge flange extending outward on its side; the other auxiliary plate has a second joining slope that joins with the first joining slope, and a transition surface covered by the thin edge flange on its side.

[0016] Compared with the traditional beveled joint method, this utility model uses a thin-edged flange to cover the transition surface of the other auxiliary plate. The joint structure is not easily affected by dimensional tolerances and thermal expansion and contraction of materials, and effectively prevents problems such as exposed sharp corners, misaligned edges, and fragile and easily damaged corners at the joint, thus maintaining the precision and aesthetics of the joint.

[0017] Preferably, the auxiliary board includes a back auxiliary board located on the back side of the motherboard and side auxiliary boards located on both sides of the motherboard; the back auxiliary board and the side auxiliary boards are connected.

[0018] Preferably, the upper half of the back panel and side panel are provided with a thickening slope; the bottom front end of the main board is provided with a second thickening slope; and the front ends of the main board and side panel are respectively provided with rounded corners. This can prevent sharp corners from scratching or injuring people, and also enhance the aesthetics of the shelf.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 like Figure 1 As shown, this embodiment presents a plate connection structure, including a main plate 1 and an auxiliary plate 2. The main plate 1 extends outward from its side near the auxiliary plate 2 to form a thin edge 3. The thin edge 3 and the main plate 1 are integrally formed, and the thickness of the thin edge 3 is less than the thickness of the main plate 1. The auxiliary plate 2 has a slot 5. The thin edge 3 is engaged in the slot 5 of the auxiliary plate 2. The thin edge 3 and the wall of the slot 5 are mutually positioned through a concave-convex structure, and a locking element is provided in the concave-convex structure to fix the thin edge 3 and the wall of the slot 5 to each other.

[0023] Specifically, the concave-convex structure includes: a positioning opening 4 on the outer side of the thin edge 3, and a positioning block 6 disposed inside the slot 5; the number of positioning openings 4 and positioning blocks 6 are matched, and corresponding locking elements are disposed in the positioning openings 4 and positioning blocks 6. The positioning openings 4 and positioning blocks 6 can effectively realize the mutual positioning of the main board 1 and the auxiliary board 2. Preferably, there are two or more positioning openings 4 and positioning blocks 6, which can improve the stability of the connection between the main board 1 and the auxiliary board 2. The auxiliary board 2 and the positioning blocks 6 are an integral structure.

[0024] The locking component refers to the positioning pin 7; the inner wall of the positioning port 4 and the positioning block 6 are respectively provided with mounting holes for inserting the positioning pin 7. The inner wall of the positioning port 4 and the positioning block 6 provide mounting space for the positioning pin 7, so that the positioning pin 7 can be hidden and installed inside the main board 1 and the auxiliary board 2, further improving product quality. The positioning pin 7 can effectively fix the main board 1 and the auxiliary board 2 to each other.

[0025] In this invention, the main board 1 and the auxiliary board 2 are connected by a thin edge 3 and a slot 5, which increases the contact area between them, making them tightly joined and firmly connected. This effectively reduces the visual thickness at the connection between the main board 1 and the auxiliary board 2, eliminating the bulky and rigid feel of traditional thick plate joints. It also reduces the width of the joint between them, improving the quality of the process. The use of a concave-convex structure and locking elements in the concave-convex structure to position and fix the main board 1 and the auxiliary board 2 to each other facilitates alignment and fixation during assembly, improving product quality.

[0026] The panel connection structure of this utility model can be used in panel furniture, such as for connecting internal panels of shelves, cabinets, cabinet doors, and desktops.

[0027] Example 2 This embodiment provides a shelf, such as... Figures 2 to 4 As shown, the system includes a main board 1 and auxiliary boards 2; the auxiliary boards 2 are positioned on one or both sides of the main board 1. In this embodiment, there are three auxiliary boards 2, including a back auxiliary board 2 located on the back of the main board 1 and side auxiliary boards 2 located on both sides of the main board 1; the back auxiliary board 2 and the side auxiliary boards 2 are connected to form a semi-enclosed blocking structure on the outside of the main board. In practical applications, there can also be multiple auxiliary boards, forming a fully enclosed blocking structure on the outside of the main board; or there can be one auxiliary board, positioned on one side of the main board; or there can be two auxiliary boards, positioned on both sides; or even other blocking methods. This shelf can prevent items placed on the main board 1 from falling, improving the safety of the items.

[0028] The main board 1 and the auxiliary board 2 are connected by the board connection structure described in Embodiment 1, which enables the shelf to have good mechanical strength and good product quality.

[0029] The preferred design is as follows: the upper half of the back panel 2 and the side panel 2 are both equipped with a thickening bevel 9; the bottom front end of the main panel 1 is equipped with a thickening bevel 8; and the front ends of the main panel 1 and the side panel 2 are each equipped with a rounded corner 10. This design can prevent sharp corners from scratching or injuring people, and also enhance the aesthetics of the shelf.

[0030] Example 3 The difference between this embodiment of a shelf and embodiment two is that: Figure 5 and Figure 6 As shown, of the two auxiliary plates 2 that are joined together, one of the auxiliary plates 2 has a first joint slope 11 and a thin edge flange 13 extending outward on its side; the other auxiliary plate 2 has a second joint slope 12 that is joined with the first joint slope 11, and a transition surface 14 covered by the thin edge flange 13 on its side.

[0031] Compared with the traditional beveled joint method, this utility model uses a thin-edged flange 13 to shield the transition surface 14 of the other auxiliary plate. The joint structure is not easily affected by dimensional tolerances and thermal expansion and contraction of materials, and effectively prevents problems such as exposed sharp corners, misaligned edges, and fragile and easily damaged corners at the joint, thus maintaining the precision and aesthetics of the joint.

[0032] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
