Casing assembly convenient to disassemble and assemble

Abstract

The invention discloses a casing assembly convenient to disassemble and assemble. The casing assembly comprises an upper cover and a lower cover, wherein the lower cover comprises a lower cover base plate and four lower cover side plates arranged on four sides of the lower cover base plate; the upper cover comprises an upper cover base plate and four upper cover side plates arranged on four sides of the upper cover base plate; the upper cover is arranged in a space defined by the lower cover side plates, and both the upper cover side plates and the lower cover side plates are located on same sides; a lower cover convex point is arranged on one side, close to an upper cover side plate, of a lower cover side plate; and an upper cover convex point is arranged on one side, close to a lower cover side plate, of an upper cover side plate, and the upper cover convex point is matched with the lower cover convex point in a clamping manner. According to the casing assembly, matched convex points and grooves are arranged on the upper cover and the lower cover, so that the upper cover and the lower cover can be assembled and disassembled rapidly, and the production efficiency is improved; and the convex points and the grooves are simple in structure, the manufacturing process is simple, and the convex points and the grooves are not deformed after disassembled and assembled repeatedly, so that assembly between the upper cover and the lower cover is guaranteed to be good, and the service life of the whole casing assembly is prolonged.

Description

technical field [0001] The invention relates to a casing assembly, in particular to a casing assembly which is easy to assemble and disassemble. Background technique [0002] The shell assembly generally includes an upper cover and a lower cover, and the upper cover and the lower cover are generally connected by snap-fit ​​connection or bolt connection during the assembly process. The buckle connection method needs to design a matching buckle on the upper cover and the lower cover, which increases the difficulty of manufacturing, and the buckle is easily deformed or even damaged after long-term repeated use, resulting in poor assembly between the upper cover and the lower cover ;The bolt connection method needs to open bolt holes on the upper cover and the lower cover, and additional bolts and nuts are required to connect the upper cover and the lower cover. Not only the manufacturing process is more, but the material cost is also high. At the same time, a wrench is required...

AI Technical Summary

Problems solved by technology

The buckle connection method needs to design a matching buckle on the upper cover and the lower cover, which increases the difficulty of manufacturing, and the buckle is easily deformed or even damaged after long-term repeated use, resulting in poor assembly between the upper cover and the lower cover ;The bolt connection method needs to open bolt holes on the upper cover and the lower cover, and additional bolts and nuts are required to connect the upper cover and the lower cover. Not only the manufacturing process is more, but the material cost is also high. At the same time, a wrench is required in the disassembly process Unscrew the nuts from the bolts or screw the nuts on the bolts, resulting in a complicated disassembly process of the upper cover and the lower cover, slow disassembly speed and low production efficiency
