[0002] There are many types of existing board materials for making furniture. Different types of board materials have different characteristics and are suitable for different furniture making needs. For example, there are solid wood boards made of natural wood, multi-layer boards made by gluing together multiple layers of thin sheets, particle boards made by pressing a mixture of sawdust and adhesives, fiberboards made by pressing wood fibers and glue, solid wood composite boards made by gluing together multiple layers of solid wood veneers, PVC boards made of polyvinyl chloride materials, and so on. These existing board materials all have specific advantages and limitations. When making furniture with certain strength requirements, boards with a certain thickness are required. For example, boards with a thickness of more than 45 mm are required. If existing boards with a certain thickness are used, the overall weight of the boards will be heavy and there will be a waste of materials. Therefore, in order to meet the above requirements, a sandwich panel is needed that can meet the thickness requirements, save materials, and is lightweight. Utility Model Content

[0029] A classic embodiment of this application, such as Figure 1As shown, the present application is a sandwich panel, comprising a first panel 10 and a second panel 20, both of which have a panel surface, the panel surfaces of the two panels facing each other and connected by a plug-in, and a gap 40 of a certain width is formed between the two panels, thereby forming a sandwich panel. Figure 2 and Figure 3 , the plate surface on the first plate 10 is 115, and similarly, the second plate 20 also has a plate surface, and the two plates are connected by the plug-in 11 to form a sandwich plate, such as Figure 4 As shown, a gap 40 is formed between the two panels, and the width of the gap 40 is fixed. The resulting sandwich panel not only meets the thickness requirements for finished furniture, but also provides a certain strength without making the overall weight of the sandwich panel excessive. It also saves material because no core layer is required. Furthermore, the sandwich panel can be processed or fine-tuned on-site, effectively reducing the impact of panel tolerances on the overall appearance of the sandwich panel.
[0030] As another classic embodiment of the present application, Figure 1 、 Figure 2 and Figure 6d As shown, a sandwich panel of the present application includes a first panel 10, a second panel 20, a first plug-in 11 and a second plug-in 12, wherein the first plug-in 11 is fixedly connected to the panel surface 115 of the first panel 10; Figure 3 As shown, the first plug-in 11 and the board surface 115 form a socket 111. Similarly, the second plug-in 21 is fixedly connected to the second plate 20, and the second plug-in 21 and the board surface of the second plate 20 form a second socket. The first socket 111 and the second socket are plugged into each other, and a covering strip 30 is provided between the first plate 10 and the second plate 20 as a filling layer of the sandwich panel. The covering strip 30 is fixedly connected to the board surface 115 of the first plate 10 and abuts against the first plug-in 11, thereby forming the sandwich panel of the present application. This makes the production of the sandwich panel very simple, and it can be set and installed according to actual needs on the site of the application scenario. It is also very convenient to adjust the position, and it can reduce the interlayer material of the sandwich panel core, saving interlayer material.
[0031] Another classic embodiment of the present application is as follows Figure 1 、 Figure 3 and Figure 5As shown, the first plug-in 11 and the second plug-in 12 of the sandwich panel have the same structure. They both include two fins 112 and 114 arranged in a stepped manner, wherein the first fin 114 is used to be fixed to the board surface. The first fin 114 is provided with a plurality of mounting holes 110, and the board surface is provided with through holes. The plug-in is fixed to the board surface by screws in conjunction with the mounting holes. A plurality of reinforcing ribs 113 are provided between the first fin 114 and the second fin 112, which can effectively strengthen the strength of the plug-in and make the sandwich panel have greater strength. A chamfer is provided at the free end of the second fin 112 away from the first fin 114, which can increase the tightness when the first plug-in 11 and the second plug-in 12 are plugged into each other. The socket 111 is formed between the second fin 114 and the board surface.
[0032] As another embodiment of the present application, Figure 2 and Figure 3 As shown, the first panel is provided with two rows of first plugs 11 on either side, with the sockets of the two rows of first plugs 11 facing outward. The second panel is provided with two rows of second plugs 12 corresponding to the two rows of first plugs 11, with the sockets of the two rows of second plugs 12 facing inward. The two rows of first plugs 11 and the two rows of second plugs 12 are tightly interlocked with each other through their corresponding sockets. This embodiment can achieve higher tightness and strength of the sandwich panel.
[0033] As another embodiment of the present application, Figure 1 and Figure 3 As shown, a covering slat 30 is sandwiched between the first plate 10 and the second plate 20. The first plate 10 and the second plate 20 are connected by plug-ins to form a sandwich panel, which is also the finished product of the sandwich panel. The covering slat 30 is sandwiched between the first plate 10 and the second plate 20. The covering slat 30 serves as the core layer of the sandwich panel. At the same time, the covering slat 30 and the plug-in are in contact with each other, acting as the filling layer of the sandwich panel and also serving as a positioning function. By providing the covering slat as the core layer of the sandwich panel, material preparation and processing are facilitated, and compared with the whole sandwich layer in the prior art, more materials can be saved. Since the plug-in is in the same horizontal direction, it can position the covering slat after installation, and the installation operation is very simple.
[0034] As another embodiment of the present application, Figure 2 and Figure 3As shown, the surface 115 of the first panel 10 and the surface 115 of the second panel 20 can be fixedly connected with a plurality of first plug-ins 11 and a plurality of second plug-ins 21, respectively, so that each first plug-in corresponds to each second plug-in and plugs into each other. In this embodiment, four first plug-ins 11 can be fixedly connected to the first panel 10. Similarly, four second plug-ins 21 can be provided on the second panel 20, so that they correspond to each other and plug into each other. A covering strip 30 is fixedly connected to the first panel 10. The thickness of the covering strip is 8-14 mm, and the optimal thickness is 10 mm. The covering strip 30 can be fixedly connected to the first panel 10 by screws. That is, the covering strip 30 has screw holes, and the corresponding surface 115 of the first panel 10 also has screw holes. Finally, the covering strip 30 is fixedly connected to the first panel by screws, so that the covering strip 30 is sandwiched between the first panel 10 and the second panel 20. Similarly, the covering strip 30 can also be fixedly connected to the surface of the second piece 20 by screws, so that it is also sandwiched between the first plate 10 and the second plate 20; and the covering strip 30 is abutted against the second plug-in, thereby forming the sandwich panel of the present application. Figure 5 As shown, the first plug-in 11 is provided with a plurality of mounting holes 110, which are preferably arranged as follows: Figure 5 As shown, two mounting holes 110 are provided, and screw holes are provided in the panel. The first plug-in 11 is fixedly connected to the panel surface 115 of the first panel 10 via screws. The first plug-in 11 is Z-shaped. The second wing 112 of the first plug-in 11 forms a socket 111 with the panel surface 115 when the first plug-in 11 is fixedly connected to the first panel 10. The first plug-in 11 is also provided with a plurality of reinforcing ribs 113, the optimal number of which is three. The two mounting holes 110 are respectively located between the three reinforcing ribs 113. The second plug-in 12 has the same structure as the first plug-in 11. The second socket formed by the second plug-in 12 plugs into the first socket 111, thereby forming and securing the sandwich panel. The interference fit between the second wing 112 of the first plug-in 11 and the socket formed by the second plug-in 12 also increases the connection tightness between the two plugs, thereby enhancing the strength of the sandwich panel.
[0035] As another embodiment of the present application, Figure 6b and Figure 6c and Figure 6d As shown, the end faces of the first plate 10 and the second plate 20 of the sandwich panel are both inclined to form an open channel, that is, the side surfaces of one side of the first plate 10 and the second plate 20 are inclined, so that the sandwich panel can be made into different shaped edges, thereby being able to adapt to various application scenarios.
[0036] As another embodiment of the present application, Figure 2 、 Figure 3 and Figure 6aAs shown, the covering slats 30 protrude beyond the said gap 40, and the covering slats 30 are fixedly connected to the panel surface 115, so that the covering slats 30 protrude beyond the first panel 10 and the second panel 20. The covering slats 30 are clamped between the first panel 10 and the second panel 20 and also protrude outward, so that the covering slats 30 protrude beyond the first panel 10 and the second panel 20, that is, the covering slats 30 protrude beyond the entire sandwich panel, so that the sandwich panel can adapt to various different application scenarios.
