Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furniture, and more particularly to a nail-free metal cabinet body. BACKGROUND

[0002] At present, the transmission cabinet body is basically a wooden board type furniture of particle board or fiber board. The cabinet body is generally composed of side plates, a bottom plate, a top plate and a back plate. According to user needs, a layer plate for separating the space of the cabinet body can be added in the cabinet body. The manufacturing and splicing process is complex and time-consuming. The structure of the cabinet body after splicing is not strong in disassembly and replacement, and has the defect of easy deformation and cannot be repaired. At present, there are also custom cabinet bodies made of metal materials. However, the metal cabinet bodies on the market are relatively thick, and there are still large gaps between the spliced parts of the assembled parts of the metal cabinet body. The spliced adapter usually exposes screws, angle codes and other components, and still cannot meet the increasingly high aesthetic requirements of consumers. Moreover, the assembly of the existing metal cabinet body is still time-consuming and laborious, and the operability of disassembly, replacement and repair is still not strong. The layer plate of the existing cabinet body usually uses a layer plate support or a layer plate nail to realize installation. First, the layer plate support and the layer plate cannot be connected to a tight joint, and the aesthetic appearance is poor. In addition, the layer plate support and the layer plate are different in material, which is easy to have color difference. If the same material is forcibly used, a large number of layer plate supports of different colors need to be opened, which greatly increases the production cost. Second, when the layer plate nail is used to fix the layer plate from the outside of the cabinet side plate, the positioning is not accurate and easy to deviate, and the stress is uneven, which can easily cause damage to the surface of the cabinet body, cracking of the plate, and edge and corner blowout. The exposed nails or screws also affect the appearance of the outside.

[0003] The prior art CN202545472U discloses a full-aluminum furniture cabinet body frame connecting angle code, which uses a plug-in method to prevent screw exposure. However, the plug-in cabinet side will obviously have a plug-in gap. In order to realize the plug-in of the front side plate and the top and bottom plates, a straight splicing 90° corner splicing method is used, which results in poor overall appearance. Finally, the cabinet body is very easy to deform.
