Cabinet structure

Abstract

The invention provides a cabinet structure. The cabinet structure comprises a framework, a cover plate and side plates, wherein the side plates are arranged around the framework. The framework comprises an upper frame and a bottom frame. The framework is formed by connecting the upper frame with the bottom frame through a corner connector and a column profile. The upper frame and the bottom frame are formed by respectively connecting two crossbeam profiles with two longitudinal beam profiles. The column profile is in a symmetrical structure with a sectional split line as the center. The cabinet structure further comprises a dustproof drain connected with the outer wall of the framework. The dustproof drain comprises an end face connected with the outer wall in parallel. The end face transitions to an airfoil through a U-shaped support section. Sealing elements are respectively arranged between the cover plate and the side plate and between the upper frame and the bottom frame. A dust trench is formed by the edge of the cover plate, the edge segment of the side plates and the dustproof drain. A labyrinth seal 1 is formed by the end face, the cover plate and the sealing element. A labyrinth seal 2 is formed by the airfoil, the side plates and the sealing element. Due to the structure design of three seals of the dust trench, the labyrinth seal1 and the labyrinth seal 2, the cabinet structure is provided with good sealing, enough industrial production (IP) level, and therefore the cabinet structure is capable of adapting the harsh industrial environment.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a cabinet, in particular to a frame structure of the cabinet. Background technique [0002] The cabinet is generally made of cold-rolled steel plate or alloy. It is used to store the objects of computers and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment in an orderly and neat manner to facilitate equipment maintenance. . Cabinet materials generally use thin steel plates, steel profiles of various cross-sectional shapes, aluminum profiles, and various engineering plastics. The cabinet frame is usually composed of longitudinal beam profiles, beam profiles and column profiles. In the prior art, there are usually two ways to assemble longitudinal beam profiles, beam profiles and column profiles: one is to cut at a 45° bevel angle at the connection angle between the longitudinal beam profiles...

AI Technical Summary

Problems solved by technology

However, the waterproof structure of the bar-shaped diversion groove cannot provide sufficient waterproof function for the cabinet, and cannot adapt to the harsh industrial environment

In addition, in order to make the general sealing material have good protective performance, a relatively large extrusion force is required, and long-term hard extrusion will shorten the service life of the sealing material. The precision requirements for production are relatively high, which is not conducive to the improvement of productivity
