Abstract

The utility model discloses a grounding ring capable of being adjusted in a torsional mode, which comprises a wire clamp fixing base and the main body of a grounding ring, wherein the lower end of the wire clamp fixing base and the upper end of the grounding ring are respectively provided with an upper torsion base and a lower torsion base, the upper torsion base and the lower torsion base are both internally provided with a sliding slot, the upper torsion base and the lower torsion base are internally connected to a connecting rod which slide in the sliding slots up and down in a matched manner, the connecting rod is sleeved by an extension spring, and two ends of the extension spring are connected to the bottom parts in the sliding slots of the upper and lower torsion bases. The grounding ring disclosed by the utility model is simple and reasonable in structure and convenient to install and use, and adopts the design of torsional connection between the wire clamp fixing base and the grounding ring. Corresponding torsional operations can be carried out on the grounding ring according to requirements when the grounding ring is used, thereby effectively improving the work efficiency. In addition, the grounding ring adopts an inverted trapezoidal design, thereby effectively saving materials, and reducing the production cost.

Description

A kind of ground loop that reverses adjustment

Technical field

The utility model relates to used for transmission line earth protective device, is specially a kind of ground loop that reverses adjustment.

Background technology

In power industry, in order to meet the service requirement that prevents Broken of Overhead Insulation Lines By Lightning, need to earthing device be installed in the load side of line insulator, by the wire ground connection of inspecting state, to guarantee the life safety of staff when overhauling, and existing reasonable not for wire being transitted to the grounding loop structure of earthing device, materials are many, and cost is high, and can not reverse as required while using, convenient not while therefore using, affect operating efficiency.

Utility model content

The purpose of this utility model is to provide a kind of ground loop that reverses adjustment, traditional reasonable not for wire being transitted to the grounding loop structure of earthing device to solve in prior art, materials are many, cost is high, and can not reverse as required while using, therefore convenient not while using, affect the problem of operating efficiency.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of ground loop that reverses adjustment, it is characterized in that: include wire clamp holder and ground loop main body, described wire clamp holder lower end and ground loop upper end are separately installed with reverses seat and lower torsion seat, in described upper torsion seat and lower torsion seat, be equipped with chute, in described upper torsion seat and lower torsion, be connected with and slide up and down the connecting rod being engaged in chute, on described connecting rod, cover has extension spring, described extension spring two ends to be connected to upper and lower torsion seat chute inner bottom part.

Described a kind of ground loop that reverses adjustment, is characterized in that: described connecting rod two ends respectively and ground loop main body inner with wire clamp holder are electrically connected to.

Described a kind of ground loop that reverses adjustment, is characterized in that: described ground loop main body is inverted trapezoidal, and lower end minor face is arranged to expose the connecting portion of metal part.

The beneficial effects of the utility model are:

The utility model is simple and reasonable, easy to install, between wire clamp holder and ground loop, adopt the design can torsional mode being connected, during use, can to ground loop, carry out corresponding twist operation as required, effectively improved operating efficiency, and ground loop adopts inverted trapezoidal design, has effectively saved materials, has saved production cost.
