Rotary e grounding wire clip

Abstract

The invention relates to a rotary grounding wire clip, which comprises a wire clip device and an operating rod, wherein the wire clip device comprises a first wire clip provided with an inner cavity and a second wire clip; the inside of the inner cavity of the first wire clip is connected with a connecting sleeve; the inside of the connecting sleeve is in threaded connection with a rotary rod of which the upper end is provided with adjusting threads, the lower end of the rotary rod is provided with a rectangular hole in which a pin is inserted, and both ends of the pin are radially fixed on a U-shaped holder connected with the operating rod; the outer wall of the U-shaped holder is provided with a ring-shaped groove sleeved by a fixing sleeve; and one side of the fixing sleeve is fixedly provided with a turning positioning fixing disk. The wire clip has the characteristics of tight connection of the grounding wire and the lead, high insulating strength, simple structure, beautiful appearance, easy operation, convenient carrying and the like.

Description

technical field [0001] The invention relates to an electric safety appliance, in particular to a rotary ground clamp for hooking a short-circuit ground wire. Background technique [0002] In the maintenance of electrical equipment and lines, the short-circuit grounding wire is an indispensable safety tool. The purpose of short-circuit grounding on the equipment and lines to be repaired is to discharge residual charges, prevent dangerous voltages and arcs when the power comes on suddenly, or induce voltages generated by nearby live equipment and lines, causing people to be electrocuted or severely burned. The personal safety of workers. For this reason, various cable short-circuit ground wire clamps have occurred. Such as Chinese patent ZL02218990.4 discloses the cable short-circuit grounding clamp is composed of an insulating rod part and a clamp part, and has the characteristics of small size and light weight. However, the clamps of the current general-purpose portable s...

Problems solved by technology

However, when it is required to hang the ground wire to the wire at the front end of the tension clamp on the tension pole tower, since the angle between the joystick held by the operator and the wire is between 45 degrees and 60 degrees, it is impossible to ensure that the ground wire clamp and the wire clamp The angle is 90 degrees or close to 90 degrees, so that the grounding wire clip cannot clamp the wire, forming a false hanging phenomenon. When there is strong wind or the wire vibrates, the grounding wire clip is easily separated from the wire, causing the operator Working without grounding wire protection will leave hidden dangers for major safety accidents that cause group injuries and deaths
