AI Technical Summary

Technical Problem

Traditional methods of cable penetration through walls are not protected, making them susceptible to scratches and pressure from sharp wall edges, which can damage the insulation layer and cause safety hazards such as leakage and short circuits. In addition, existing conduit fixing specifications are difficult to adapt to walls of different thicknesses, making installation cumbersome.

Method used

The system uses a protective arc-shaped plate and a telescopic arc-shaped plate to form a complete circular tube structure. It is adjusted by a limit rod and a locking nut to form a protective sleeve that fits tightly against the wall, adapting to walls of different thicknesses. It is fixed with gaskets and locking nuts to achieve quick installation.

Benefits of technology

It effectively protects the cable insulation layer, prevents leakage and short circuits, improves installation convenience, and adapts to the protection needs of walls of different thicknesses.

Abstract

This utility model discloses an indoor power distribution cable wall-penetrating protective installation device, relating to the field of wire installation technology. The device includes a first protective arc plate and a second protective arc plate. The first protective arc plate is hinged to the second protective arc plate. The second protective arc plate has a fixing structure and an adjustment structure, which is located on the first protective arc plate. This device, through the first and second protective arc plates and the first and second telescopic arc plates, forms a complete circular tube structure, completely enclosing the wall-penetrating cable and isolating it from the sharp edges of the wall. Even with long-term use, it effectively protects the cable insulation layer, preventing dangerous situations such as leakage and short circuits. The protective sleeve is fixed by gaskets and locking nuts, allowing for flexible adjustment of the overall length of the protective device to ensure a tight fit to walls of different thicknesses, further improving the ease of installation.
