Description

Technical Field

[0001] The utility model relates to the field of low-voltage switch cabinets, and more specifically to a cabinet sealing structure of a low-voltage switch cabinet. Background Art

[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the branch control switch. Each branch is set according to its needs. Low-voltage switch cabinet is a type of switch cabinet.

[0003] In order to improve the airtightness inside the low-voltage switch cabinet, in addition to strengthening the sealing measures at the inlet and outlet of the cabinet, the sealing of the connection between the cabinet and the cabinet door is also particularly important. Most of the existing cabinet door connections are mostly achieved by installing a circle of sealing rings on the cabinet door so that it can contact the cabinet opening to achieve a sealing effect. However, this structure is relatively simple. Over time, the sealing ring is prone to aging and hardening, and the soft fit with the edge of the cabinet opening decreases, thereby affecting the sealing effect of the connection. Therefore, we propose a cabinet sealing structure for a low-voltage switch cabinet to solve the above problems. Utility Model Content

In addition, the rubber sealing strips are respectively installed on corresponding floating plates, and the floating plates are supported by supporting springs and can be retracted and extended at the telescopic box, so that the floating plates can be firmly pressed against the rubber sealing strips, forcing the rubber sealing strips to contact and seal with the outer edge of the cabinet opening, thereby reducing the probability of loose contact between the rubber sealing strips and the outer edge of the cabinet opening due to aging and hardening.
