Tensioning device for weak current cable used for electronic information site

Abstract

The invention provides a tensioning device for a weak current cable used for an electronic information site. A body, side grooves, rotation pieces, moving pieces, tensioning rods and moving plates areincluded. The body is of a rectangular structure, and the outer side of the bottom of the body is of an oblique structure. A seal plate is arranged at the front end of the body, and the interior of the right side of the seal plate is provided with a clamping piece of a wedged protruding structure. Each side groove comprises a bottom groove and inserting grooves, wherein the side groove is of a rectangular structure, the bottom of the side groove is provided with the bottom groove of a T-shaped structure, and the inserting grooves are formed in the two sides of the top end of the side groove.The moving pieces are used for being installed at the outer ends of the rotation pieces, when the rotation pieces rotationally pull the cable through coil springs, the inserting rods on the inner sides of the moving pieces can be inserted into inserting holes, accordingly when the rotation pieces outward rotate and the cable is pulled out to be used, the inserting rods can be inserted into the inserting holes, and cable pull-back due to rotation piece rotation is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and more specifically relates to a tensioning device for a weak current cable on site based on electronic information. Background technique [0002] In the electronic information field, it is usually necessary to perform line connection and extend the plug-in line through cables, and when the cables are used, tensioning devices are usually required. [0003] For example, the application number: CN201811620821.X relates to a cable tensioning structure, including a "匚"-shaped horizontal channel, a horizontal first guide groove is formed on the bottom surface of the horizontal channel, and the two ends of the horizontal channel are inserted A first guide block is provided, and a circular first chassis is formed on the front end surface of the first guide block. A first support shaft is formed in the center of the first chassis, and a guide wheel is hinged on the first support shaft....

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a tensioning device for weak current cables based on electronic information field, to solve the problem that when the existing cable tensioning device is in use, the cable usually rebounds automatically through the coil spring and cannot After being pulled to any length, it is automatically fixed, and the cable cannot be fixed at an appropriate length conveniently according to the demand. Moreover, when the existing cable tensioning device is in use, it cannot Auxiliary cushioning impact, unable to protect the cable, the cable is prone to damage
