Electrostatic grounding clip

Abstract

The invention discloses an electrostatic grounding clip which comprises an upper clip and a lower clip. The upper clip and the lower clip are arranged in a running fit manner, threaded holes are formed in the ends of the upper clip and the lower clip, shells are matched with the threaded holes, steel nails, springs and electromagnets are arranged in the shells, permanent magnets are arranged in the steel nails, the springs are arranged at the upper ends of the steel nails, each electromagnet is connected with the other end of the corresponding spring, fixing blocks are arranged on the upper sides of the shells, buttons for controlling the electromagnets are arranged on the fixing blocks, through holes are formed in the fixing blocks, and handles are fittingly inserted in the through holes.The electrostatic grounding clip has the advantages that repulsive force can be generated on the steel nails by the electromagnets under the condition of thick surface insulating layers, and accordingly effects of applying force to the steel nails can be realized; the external shells can rotate if the surface insulating layers still cannot be torn, the steel nails further can downwardly move, accordingly, double-layer force application effects can be realized, and the electrostatic grounding clip is quite convenient for operators.

Description

technical field [0001] The invention relates to the technical field of electrostatic grounding, in particular to an electrostatic grounding clamp. Background technique [0002] In petrochemical, pharmaceutical, paint, coating and other fields, in order to eliminate the hazards of static electricity accumulation generated during storage and transfer of flammable and explosive liquids, different types of electrostatic grounding clamps are usually used. Electrostatic grounding clamp is a mechanical structure used to extract static electricity from objects, usually connected to grounding piles or grounding grids, the clip is clamped on the object, and penetrates the paint, stains or oxide layers on the surface of the object through sharp steel nails The insulating layer enables the static electricity accumulated on the object to be conducted away, eliminating potential static electricity hazards. [0003] The electrostatic grounding clamp mainly relies on static pressure and th...
