A kind of MPP cable protection tube with the function of preventing cable twisting and accumulation

Abstract

The invention discloses an MPP cable protection pipe with the function of preventing twisting and accumulation of cables. The fixed rod is fixed with a metal ring, and the symmetrical sliding sleeve on the metal ring is provided with clamping blocks. The fixed rod is located between two clamping blocks, and the two clamping blocks are connected by springs. A clamping rod is provided, and the clamping rod is set through the side wall of the pipe body. A rotation control device for the clamping block is provided in the pipe body. The rotation control device includes a rotation rod three installed in the annular cavity. The rotating rod three is fixedly sleeved with gear one, and two rotating rods one are also rotated in the annular cavity, and the two rotating rods one are fixedly sleeved with guide wheels and gear two. The invention can fix the cables in the protection tube and prevent the cables from twisting and accumulating in the protection tube.

Description

technical field [0001] The invention relates to the technical field of cable protection tubes, in particular to an MPP cable protection tube with the function of preventing cables from twisting and accumulating. Background technique [0002] The cable protection tube refers to a metal protection tube with a certain mechanical strength laid on the outer layer of the cable in order to prevent the cable from being damaged. The cable protection tube is mainly installed at the intersection of the communication cable and the power line. The main function is to prevent the short circuit caused by the disconnection of the power line. Accidents cause communication cables and wire ropes to be electrified to protect cables, switches, and core boards, so that the whole machine will not be burned out, and also play a certain role in isolating the magnetic field interference of power lines. There are many types of cable protection tubes, and the main ones currently used are It is the MPP ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: because the thickness of the cable is much smaller than the size of the MPP cable protection tube, when the cable passes through the MPP cable protection tube, it is easy to produce in the MPP cable protection tube. The phenomenon of twisting and accumulation occurs, which wastes the cable. At the same time, a large number of twisting and accumulation phenomena for a long time will cause friction between the cables and destroy the efficacy of the cable. A MPP cable protection tube with the function of preventing cable twisting and accumulation is proposed.
