Description

Technical Field

[0001] This utility model relates to the field of metal chassis technology, and in particular to a modular and detachable metal chassis. Background Technology

[0002] Metal materials refer to chassis made of metal materials. Metal chassis are widely used as housings for various electrical components due to their stable structure, excellent heat dissipation and dustproof performance, and good electromagnetic shielding effect. Furthermore, to facilitate the installation of metal chassis, technicians have developed modular and detachable metal chassis.

[0003] As disclosed in Utility Model No. CN220606297U, a combined detachable metal chassis relates to the field of metal chassis technology. It includes a base plate, with front and rear side plates overlapping the top of the base plate. Rotary shafts are rotatably connected to the inner sides of both ends of the base plate. Left and right side plates are fixedly connected to the outer walls of the rotating shafts. A second insert block is fixedly connected to the outer wall of one end of the base plate. Threaded grooves are formed on the inner walls of the front and rear side plates. Rotating columns are rotatably connected to the inner sides of the outer walls of the front and rear side plates. A threaded limiting tube is rotatably connected to one end of the rotating column. This utility model uses a fixed disc on one side of the extrusion tube to compress a second spring. By compressing the extrusion tube, the inner side of one end of the extrusion tube is fitted onto the outer wall of the limiting column for limited sliding extension and retraction. This causes the fixed disc to disengage the outer wall of one side of the snap-fit ​​block from the inner side of the outer wall of the second insert block, thus achieving the effect of separating and rotating the base plate from the left and right side plates. This solves the problem of the overly simplistic installation method of existing metal chassis panels. However, this technical solution uses a complex connection structure to connect and fix the chassis components during application. The structure is complex and easily damaged, and the disassembly and assembly operations are relatively inconvenient. There is a technical problem that it is not convenient and quick to assemble, install and disassemble the metal chassis. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a modular detachable metal chassis, which can solve the technical problem that the chassis components are connected and fixed through a complex connection structure, which is easy to damage and inconvenient to disassemble and assemble.

[0007] As a preferred embodiment of the present invention, the first stabilizing protrusion is embedded in the interior of the first limiting groove, and the second stabilizing protrusion is embedded in the interior of the second limiting groove.

[0008] As a preferred embodiment of this utility model, the heat dissipation grooves are arranged at equal intervals inside the left and right side plates, and the heat dissipation grooves are parallel to each other.

[0009] As a preferred embodiment of the present invention, the mounting assembly includes an assembly plate, which is disposed at the rear end between the inner sides of the front and rear side plates, a buffer pad is provided at the front end of the assembly plate, and a positioning screw hole is provided at the front end inside the assembly plate.
