Description

Technical Field

[0001] The utility model relates to a cabinet body, in particular to an electric cabinet, and belongs to the technical field of electric cabinet bodies. Background Art

[0002] The electric cabinet is a cabinet structure used for the integrated installation of various electrical components. The electric cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. The electric cabinet is suitable for occasions with relatively dispersed loads and fewer circuits. In this way, it can be used to provide power to control the start and stop operations of each circuit. As the final equipment of the power distribution system, the electric cabinet is an indispensable equipment in the entire system.

[0003] In the prior art, a sealed insect-proof electric cabinet body is disclosed in announcement number CN216672209U. By setting a sealing mechanism, both the rubber cone ring and the sealing soft rubber ring can be deformed and expanded, so that under the action of the deformation rebound force, the rubber cone ring and the sealing soft rubber ring are more closely attached to the outside of the cable. The fitting sealing tape is wrapped around the outside of the cable along a spiral line, and the gap at the bottom of the cable is spirally wrapped and sealed and fixed. The insects crawling on the cable are lured into the insect trap box by insecticides for killing. It not only plays a role of multiple sealing and insect prevention, but also can perform insecticidal operations, effectively preventing insects from entering the cabinet. The interior of the cabinet has better safety protection. The existing cabinet has a rubber ring at the cable insertion position to achieve a sealing effect, but in fact there is often a large gap at the connection between the cabinet door and the cabinet, that is, the gap needs to be sealed and strengthened to achieve a better insect-proof and airtight effect. However, the existing technology often only seals by setting a single sealing strip, which cannot maximize the sealing effect. Secondly, in order to improve the structural strength of the cabinet door, side edges are often set at the four corners of the cabinet door, and there will be certain gaps at the docking positions of the side edges, which will also affect the overall sealing of the electric cabinet.
