Cable hole plugging device for power cabinet

Abstract

The invention discloses a cable hole plugging device for a power cabinet. The cable hole plugging device comprises a trough-type shell, wherein a threading hole is formed in an inner-trough bottom surface of the trough-type shell; the inner-trough bottom surface of the trough-type shell is symmetrically provided with a plurality of groups of slideways in two sides of the threading hole; a slideable adjusting slide plate is arranged in each slideway; rack-shaped clamping teeth are arranged in the middle of the upper surface of each adjusting slide plate; two rotating shafts are symmetrically arranged at two sides in the trough of the trough-type shell; and locating cams are respectively arranged on the rack-shaped clamping teeth on each adjusting slide plate and are used for achieving a location after the adjusting slide plates adjust. The cable hole plugging device for the power cabinet has the beneficial effects of being simple in structure and convenient to use; a gap after threading of the threading hole can be reduced to the minimal size by adjusting the size of the threading hole through the adjusting slide plates; the adjusting slide plates can be located by rotating the locating cams by the clamping teeth in the upper surfaces of the adjusting slide plates; a threading opening can be tightly plugged by matching with fireproofing mud; the fireproofing mud can be prevented from leaking through a support of the trough-type shell; the cable hole plugging device can be repeatedly used; and the use cost is low.

Description

technical field [0001] The invention particularly relates to a cable hole sealing device for a power screen cabinet. Background technique [0002] In order to facilitate threading when the power screen cabinet is in use, relatively large threading openings are usually set on the bottom of the power screen cabinet. In order to seal the gap left after threading, fireproof mud is usually used to block the threading port after threading. This blocking method has the following problems: [0003] 1. Since the threading hole is large and there is no support under the fireproof mud, the fireproof mud will easily leak out over time and lose its sealing effect, making the threading hole leaky, which will easily lead to the entry of mice and other small animals, thus causing accidents. [0004] 2. This sealing method belongs to one-time sealing. When the plugged power screen cabinet needs to add cables, the fireproof mud used for blocking can only be completely removed, and then plugg...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the large threading opening and no support under the fireproof mud, the fireproof mud will easily leak out over time and lose its sealing effect, making the threading port leaky, which will easily lead to the entry of mice and other small animals, thus causing accidents

[0004] 2. This kind of sealing method belongs to one-time sealing. When the plugged power screen cabinet needs to add cables, the fireproof mud used for blocking can only be completely removed, and then plugged again after threading, which is time-consuming and laborious.
