Description

Universal anti-drop ground wire clamp

Technical field:

The utility model relates to a kind of safety tool widely used in the electric power industry, in particular to a universal anti-falling ground wire clip.

Background technique:

At present, the portable grounding wire devices used in my country's power system are classified according to the connector form: single tongue type, double tongue type, screw tight type, hand-held flat mouth type, monkey head type and other types. Among them, the single tongue type and double tongue type are mainly used for safety measures when the line or bus is powered off; the screw tight type and the hand-held flat mouth type are mainly used for safety measures when the busbar is powered off. The reason why there are many forms of grounding wire devices is mainly to meet the needs of different shapes of equipment when taking safety measures in case of power failure.

Utility model content:

The technical problem to be solved by the utility model is to provide a universal anti-dropping ground wire clip which is not easy to fall off, safe and reliable.

The technical scheme that the utility model takes for solving the technical problem is:

A universal anti-falling grounding wire clamp, including a hollow insulating operating rod and a clamp joint, the clamp joint includes an upper splint and a lower splint, and the upper splint and the lower splint are connected together by tightening a torsion spring, An upper groove is arranged below the upper splint, and a lower groove is arranged above the lower splint. The groove openings of the upper groove and the lower groove correspond to each other, and the lower end of the opening end of the upper splint is distributed at an acute angle. The upper end of the corresponding lower splint is also distributed at an acute angle; the hollow insulating operating rod and the lower splint are integrated, and the upper splint is connected to the traction rope and the pressing handle inside the hollow insulating operating rod by tightening the torsion spring , a strip-shaped opening is arranged on the cylindrical wall at the middle and lower end of the hollow insulating operating rod, and the pressing handle moves up and down through the strip-shaped opening, and then drives the upper splint to open or close through the traction rope.

The two acute angles between the lower end of the opening end of the upper splint and the upper end of the opening end of the lower splint are both 80 degrees, so that the opening end of the clamp joint is in the shape of a duckbill.

A connecting fastening bolt is provided at the top angle position of the other side of the upper splint corresponding to the opening end, and the grounding wire is fixed on the upper splint through the connecting fastening bolt.

The pressing handle is processed from insulating material.

When in use, press the pressing handle of the utility model, the traction rope is tensioned, and the torsion spring is tightened to be stressed, so that the upper splint is opened, and the wires that need to be grounded are clamped at the notch of the upper groove and the lower groove; When the pressing handle of the utility model is opened, the upper splint and the lower splint are closed, and the notches of the upper groove and the lower groove are also closed thereupon, which avoids the phenomenon that the wires fall off.

Because the lower end of the opening end of the upper splint of the utility model is distributed at an acute angle, the upper end of the corresponding lower splint is also distributed at an acute angle, and both acute angles are 80 degrees, so that the opening end of the clamp joint is in the shape of a duckbill. The narrow rear side is wide, which can effectively prevent the grounding wire from falling off, has a simple structure, is safe and reliable, and is convenient to use, and has good practical value and market promotion prospect.
