Description

Novel insulating tongs of individual security line

Technical Field

The utility model relates to the field of security lines, in particular to a novel personal security line insulation gripper.

Background

The personal safety line is called as a 'safety line' by a power transmission line worker, is one of tools and instruments commonly used by the power transmission line worker, and is used frequently. The personal security wire used at present consists of a grounding clamp, a transparent sheath annealed copper wire, an insulating rope and a wire clamp. But at first, the insulating rope is easy to wear and tear in the carrying or using process, dirt such as soil, conductive grease are easy to be stained with, and the insulating property is greatly reduced by blowing, sun, rain, corrosion and aging, the insulating rope is not insulated any more, life safety of a power transmission line worker is affected, and secondly, the insulating rope and the annealed copper wire are easy to wind when being loosened or bound, so that time and labor are wasted when being disassembled, and working efficiency is reduced. In order to solve the problems caused by the insulating ropes, new components are needed to be developed to replace the insulating ropes to solve the problems.

Chinese patent document CN202308365U discloses a "personal security ground wire". The personal security grounding wire comprises a grounding clamp, a wire clamp, a grounding wire connected between the grounding clamp and the wire clamp and an insulating tail rope connected to one end of the wire clamp, wherein the wire clamp comprises two symmetrical clamping plates which are rotatably connected, a switching valve connected between the two clamping plates and used for controlling the wire clamp to be closed, and a spring connected between the two clamping plates and used for enabling the wire clamp to be closed, and the other end of the wire clamp is fixedly connected with an insulating pull rope.
