Description

Weak current cable coiling mechanism

Technical Field

The utility model relates to a cable winding device, in particular to a weak-current cable winding device.

Background

Weak cables refer to cables used for security communications, electrical equipment, and related weak current transmission purposes. When the cable is actually routed, the cable is wound on the cable winding device for the convenience of winding or drawing. Therefore, when the cable is required to be wound or pulled, the winding drum on the cable winding device is only required to be rotated forwards and backwards, and the winding and pulling of the cable can be realized. The winding width of the winding reel on the existing cable winding device is far smaller than the diameter of the cable, and because the existing cable winding device is not provided with a guiding mechanism for guiding the cable to be wound into the position, the cable is wound on the winding reel in an unordered state in the actual cable winding process, so that the winding route of the cable is disordered, the winding density of the cable is reduced, the actual winding length of the winding reel is far smaller than the design length, and even the smoothness of the cable in drawing can be influenced.
