Cover type electrical wiring duct

Abstract

The invention relates to a cover type electrical wiring duct, and the wiring duct comprises an L-shaped groove assembly, straight groove assemblies and roller assemblies; the L-shaped groove assemblyis of an L-shaped structure, the L-shaped groove assembly is of an internal hollow structure with openings in the left side and the right side, the straight groove assemblies are symmetrically installed on the left side and the right side in the L-shaped groove assembly, and the roller assemblies are arranged in the L-shaped groove assembly. According to the wiring duct, the problems that in the using process of the corner of an existing spliced cover type wiring duct, due to the fact that the corner of the wiring duct is sharp, after threading, a power line is difficult to pull when needing to be pulled again, and the power line is prone to being scratched by the sharp portion of the corner can be solved; the sealing performance of the spliced part is poor, water is likely to enter the spliced part, the service life of the power line is likely to be shortened after the power line is soaked in water for a long time, and therefore potential safety hazards exist; when a corner of a powerline is overhauled, overhauling can be conducted only by lifting up straight groove covers on the two sides, and the overhauling efficiency is low.

Description

technical field [0001] The invention relates to the technical field of electric power accessories, in particular to a cover-type electrical wiring trough. Background technique [0002] Wire trough, also known as line trough, is a protection device used to arrange power cords and network cables and fix them on the floor or wall after standardizing the power cords and network cables. The wire troughs are divided into open wire wiring troughs by use , circular wiring ducts, circular floor wiring troughs, soft circular floor wiring troughs, cover-type wiring troughs, etc., of which cover-type wiring troughs are widely used; [0003] At present, the corners of the cover-type wiring troughs on the market are usually cut and chamfered by two straight grooves and then spliced. The corners of the spliced ​​cover-type wiring troughs usually have the following problems during use: [0004] 1. Since the corner of the trunking is at a right angle, and the edge of the right angle is shar...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the corner of the trunking is at a right angle, and the edge of the right angle is sharp, it is difficult to pull the power cord after threading, and the power cord is easily scratched by the sharp corner;

[0005] 2. Since the corners are spliced ​​after being cut and chamfered with straight grooves, the sealing of the splices is poor, which may easily lead to water ingress at the splices, making the power cord soaked in water for a long time, which will easily lead to a reduction in the service life of the power cord, thereby ensuring safety. Hidden danger;

[0006] 3. When performing maintenance at the corner of the power cord, it is necessary to lift all the straight groove covers on both sides to perform maintenance, and the maintenance efficiency is low
