Problems solved by technology

[0002] Cable is an important carrier of communication technology. When it is erected or buried, a layer of cable protection tube needs to be set on its surface. For a period of time, due to the end-to-end connection of the cable protection tube, only a part of it can be removed or destroyed in turn, and it cannot be disassembled flexibly, which wastes manpower and material resources

Embodiment Construction

[0015] The present invention will be described in detail below according to the accompanying drawings and specific embodiments.

[0016] Such as figure 1 and 2 As shown, the present invention includes an inner tube 1 , a connector 2 and an outer tube 3 .

[0017] The inner tube 1 is fixed on the inner surface of the outer tube 3 through the connecting piece 2, and the inner tube 1 can rotate around its axis so that excessive torsion does not occur when the cable passes through the cable protection tube.

[0018] The connecting piece 2 includes a bearing 21 and a shielding ring 22 .

[0019] At least two bearings 21 are respectively fixed on the inner wall of the outer tube 3 , and the inner tube 1 passes through the bearings 21 , so that the inner tube 1 can rotate freely under the support of the bearings 21 .

[0020] The shielding ring 22 includes a shielding ring 221 and a fixing piece 222. The shielding ring 221 is the same as the end faces at both ends of the inner tub...

Abstract

The invention provides a telescoping cable protection pipe, and the pipe comprises an inner pipe, a connecting part, and an outer pipe. The inner pipe is fixed on the internal surface of the outer pipe through the connecting part, and the inner pipe can rotate around the axis. The outer pipe comprises an outer pipe main body and telescoping connectors located at two ends of the outer pipe main body. According to the above technical scheme of the invention, the pipe enables a cable to be able to rotate freely while the cable extends into the pipe, is more flexible in disassembly, and facilitates the timing maintenance of the cable.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a retractable cable protection tube. Background technique [0002] Cable is an important carrier of communication technology. When it is erected or buried, a layer of cable protection tube needs to be set on its surface. For a period of time, due to the end-to-end connection of the cable protection tubes, only a part of them can be removed or destroyed in turn, which cannot be dismantled flexibly, and wastes manpower and material resources. Contents of the invention [0003] The problem to be solved by the present invention is to provide a cable protection tube with retractable head and tail ends. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a retractable cable protection tube, including an inner tube, a connector and an outer tube, the inner tube is fixed on the outer tube through the connector The...
