Cabinet framework convenient for assembly and assembly method thereof

Abstract

A cabinet framework convenient for assembly comprises an upper framework and a lower framework which are formed by four corner connecting pieces and four horizontal framework rods respectively as well as four column framework rods connected between the four corners of the upper framework and the lower framework. The invention is characterized in that the framework also comprises sixteen prismatic connecting rods used for assembly connection between the column framework rod and the corner connecting pieces at the four corners of the upper framework and the lower framework, symmetrical lug boss or step counter bore is arranged on the corner connecting pieces; and the horizontal framework rod and the column framework rod are profiles with the section like '*', and the square hole cavity at the two ends of the profile can be fitly connected with the lug boss on the corner connecting piece in an embedding way. The cabinet framework convenient for assembly is simple and reasonable in structure, the framework formed by assembling the corner connecting pieces and the prismatic connecting rods is stable in structure and is high in carrying capacity, and flexibility of cabinet framework assembly, fixing assembling piece and interior installation space is strong as each framework rod forming the framework is provided with a plurality of assembly planes, thus being favorable to change of specification and type of products.

Description

technical field [0001] The invention relates to a cabinet frame, in particular to an easy-to-assemble cabinet frame and an assembly method thereof. Background technique [0002] Existing cabinets are generally composed of frames, doors, cabinet wall panels and equipment installation slats, etc., and the frame is the main structural component of the cabinet. In order to erect a rectangular shape, this cabinet consists of a rectangular frame German patent DE3344598 discloses a "cabinet frame", which has twelve frame bars and eight three-dimensional corner connectors, as figure 1 and figure 2 As shown, the frame rod 1 of this cabinet frame has two inner walls 11 facing the inner cavity of the frame. The inner walls 11 are perpendicular to each other to form a vertical edge. The two inner walls have fixing holes 12, 13, and there is the same interval between the fixing holes. This kind of frame rod can only be fixed at the connection point at a fixed interval between the two...

AI Technical Summary

Problems solved by technology

The disadvantage is that the welded frame is a whole and cannot be disassembled, resulting in higher transportation and storage costs

In addition, large-scale fixtures are required to position the frame rods during welding. After welding, the deformation is large, and it is difficult to ensure product consistency. The manufacturing cost of large-scale fixtures is relatively high.

Moreover, the processing of three-dimensional corner connectors is more difficult, because it is a three-dimensional three-fork structure, and it is time-consuming and material-intensive to produce by mechanical cutting. The cost is high and the efficiency is low, so it is not suitable for mass production.

However, the more economical casting molding process is difficult to inspect due to internal defects of the casting, which affects the reliability of the product.
