Description

Technical Field

[0001] This utility model relates to the field of protective pipe technology, specifically a corrosion-resistant protective pipe. Background Technology

[0002] Cable protection pipes, also known as cable conduits, power cable conduits, cement cable conduits, power ducts, and power cable protection pipes, are mainly installed at intersections where communication cables and power lines cross. They prevent short circuits caused by power line breaks, which could energize communication cables and steel cables, thus protecting cables, switches, circuit boards, and even the entire device from burning out. They also provide some isolation against magnetic field interference from power lines.

[0003] CN202122203576.6 discloses a cable protection pipe, relating to the field of cable protection technology. It includes multiple pipe sections connected to adjacent sections via a connecting assembly. The connecting assembly includes two hinged semi-annular plates. Protruding sealing rings are respectively provided on the left and right sides of the inner walls of the two semi-annular plates. Annular positioning grooves that mate with the sealing rings are respectively provided at the left and right ends of the pipe sections. A D-shaped connecting block is provided at the end of each semi-annular plate away from the hinge point. The two D-shaped connecting blocks are connected by a threaded sleeve. The arc-shaped surface of the D-shaped connecting block has an external thread that engages with the threaded sleeve. The top of the threaded sleeve is a sealed end. The existing technology is very inconvenient at cable bends during use, and the installation mechanism cannot be adjusted during installation and fixing. Utility Model Content
