Handheld pay-off device

Abstract

The invention relates to a handheld pay-off device which comprises an upper end cover and a lower end cover, wherein the upper end cover and the lower end cover are connected to the two ends of a middle sleeve, the lower end cover is synchronously and rotationally connected with a wire spool, a rotating shaft capable of relatively rotating is arranged in the middle sleeve, one end of the rotating shaft penetrates through the upper end cover and is connected with a grip, two fixed contact rings are synchronously and rotationally arranged on a shaft section in the middle sleeve, two rotating contact rings which rotate synchronously are arranged in the middle sleeve, and the rotating contact rings and the fixed contact rings are attached one to one; two input lines are arranged in the rotating shaft, one ends of the input lines penetrate through the side wall of the rotating shaft, extend into the middle sleeve and are electrically connected with the two fixed contact rings, and the other ends extend out of the rotating shaft; and two output lines are arranged in the middle sleeve, one ends of the output lines are electrically connected with the two rotating coils, and the other ends penetrate through the side wall of the middle sleeve and extend out of the middle sleeve. The wire spool is low above the ground and rotates vertically, the gravity center is low, the backward traction force is small, and the pay-off difficulty is low; and an interphone is connected with a wire electric brush on the wire spool, so that the interphone does not need to be stopped and disassembled during line detection, and the line detection is convenient.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a hand-held pay-off device. Background technique [0002] The pay-off device is frequently used in the line laying of the communication system. When in use, the winding reel in the pay-off device rotates to perform the pay-off work. In cities, suburbs, or areas with flat terrain, cars or motorcycles can be used as carriers, and the line-laying device can be consigned to carry out the line-laying work; however, the line laying tasks of the communication system need to be carried out in the field, limited by the complex terrain in the field, and manual work is required Setting out work on foot. At present, a backpack-type pay-off vehicle is generally used for artificial walking on foot, such as Chinese patent CN200720070597.2, a backpack-type optical cable retracting device, wherein the winding reel is rotated and installed on a bracket, and the bracket...
