Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable protection pipe technology, and in particular to a cable protection pipe with high tensile strength. Background Technology
[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength that are laid on the outer layer of cables to prevent damage. They are mainly installed at the intersection of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and steel wire ropes. This protects cables, switches, and circuit boards from being burned out, and also provides some isolation against magnetic field interference from power lines.
[0003] A search revealed in Publication No. CN221747903 U disclosed a high-tensile-strength CPVC cable protection pipe, relating to the field of cable protection pipe devices. This high-tensile-strength CPVC cable protection pipe includes a first protection pipe and a second protection pipe, with the second protection pipe located to one side of the first protection pipe. A connecting groove is formed on the outer wall of one end of the first protection pipe, and a connecting ring is fixedly connected to the outer wall of one end of the second protection pipe. This high-tensile-strength CPVC cable protection pipe, by sliding a threaded post along the outer circumferential wall of the second protection pipe, allows the threaded post to slide forward after the two sets of protection pipes are installed, and threadedly connects to the inside of the threaded cylinder, thus achieving the connection and fixation of the two sets of protection pipes. The connection of the two sets of connecting parts improves the connection effect between the two sets of protection pipes, enhances the tensile strength of the protective pipe, and facilitates the installation and disassembly of the two sets of protection pipes, avoiding the need for multiple sets of bolts and reducing the inconvenience for workers during installation and disassembly.
[0004] While the above solution facilitates the installation and removal of the two sets of protective pipes, avoids the use of multiple bolts for fixing, and reduces the trouble for workers in installing and removing the two sets of protective pipes, the sliding friction between the cable and the protective pipe results in a large friction force, which can easily damage the cable. Therefore, we propose a high-tensile-strength cable protective pipe. Utility Model Content
[0005] The main purpose of this utility model is to provide a cable protection pipe with high tensile strength. By setting the main body unit and the connecting unit, it solves the problem that the cable is easily damaged due to the large friction force caused by the sliding friction between the cable and the protection pipe.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-tensile-strength cable protection pipe includes a main body unit, a connecting unit disposed inside the main body unit, and a protective unit disposed on the surface of the connecting unit;
[0008] The main unit includes a first protective tube, a second protective tube disposed on one side of the first protective tube, and auxiliary components disposed inside the first protective tube and the second protective tube;
[0009] The connecting unit includes a first connecting flange installed at the adjacent ends of the first protective pipe and the second protective pipe, a second connecting flange installed at the adjacent ends of the second protective pipe and the first protective pipe, a locking groove formed inside the second connecting flange, a locking ring installed on the inner side wall of the first connecting flange, and a locking element disposed inside the locking groove.
[0010] Preferably, the auxiliary component includes a fixing groove formed inside the first protective tube and the second protective tube, a fixing shaft installed inside the fixing groove, and an auxiliary roller movably installed on the periphery of the fixing shaft.
[0011] Preferably, there are several auxiliary components, and the several auxiliary components are arranged in a linear array.
[0012] Preferably, the main body unit further includes anti-slip grooves formed on the side walls of the first connecting flange and the second connecting flange.
[0013] Preferably, the engaging component includes a movable through hole formed in the side wall of the engaging groove, a movable rod that movably passes through and is disposed in the movable through hole, a mating groove formed in the side wall of the engaging ring, an engaging seat installed at one end of the movable rod located inside the engaging groove, a movable base installed at the other end of the movable rod, and a return spring sleeved on the periphery of the movable rod, with one end fixedly connected to the engaging seat and the other end fixedly connected to the side wall of the engaging groove.
[0014] Preferably, the protection unit includes a sliding groove formed in the side wall of the second protection tube, a protective shell movably disposed inside the sliding groove, and a sealing element disposed on the side of the protective shell.
[0015] Preferably, the seal includes a sealing plate formed on the side wall of the protective shell, and a gripping plate mounted on the side wall of the sealing plate.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In this invention, through the main unit and connecting unit, when the cable protection tube needs protection, the side wall of the cable is brought into contact with the auxiliary roller, pushing the cable into the protection tube. During the slow entry process, the side wall of the cable continuously pushes the auxiliary roller to rotate around the fixed axis, changing the sliding friction between the cable and the protection tube into rolling friction, greatly reducing the friction between the cable and the protection tube, avoiding installation damage to the cable, and improving its service life. When convenient installation between two protection tubes is required, the locking seat can be pulled outward, causing the moving rod to move the locking seat away from the mating groove on the side wall of the locking ring, and compressing the return spring, so that the first connecting flange and the second connecting flange approach each other until the locking ring extends into the locking groove. Then, the force applied to the locking seat is removed, and under the elastic force of the return spring, the locking seat returns to its original position and engages with the mating groove on the side wall of the locking ring, thus realizing convenient installation between two protection tubes.
