Electrostatic grounding clamp with high penetration

Abstract

The invention relates to an electrostatic grounding clamp with high penetration. The electrostatic grounding clamp includes an upper clamp body and a lower clamp body. The upper clamp body and the lower clamp body are rotatably matched and arranged. Threaded holes are formed in the ends of the upper clamp body and the lower clamp body, shells are matched with the threaded holes and internally provided with steel nails, springs and electromagnets, permanent magnets are arranged in the steel nails, the springs are arranged at the upper ends of the steel nails, and the electromagnets are connected to the other ends of the springs. Fixing blocks are arranged above the shells, buttons for controlling the electromagnets are arranged on the fixing blocks, through holes are formed in the fixing blocks, handles are inserted into the through holes, and grinding discs are arranged at the ends of the handles. The electrostatic grounding clamp has the following advantages that under the condition that a surface insulation layer is relatively thick, repulsion force is generated on the steel nails through the electromagnets, a function of applying force to the steel nails is correspondingly achieved, if the ground cannot be punctured, the external shells can be rotated, the steel nails are further moved down, a double-layer force exertion effect is achieved, and the electrostatic grounding clamp is very convenient to operate for an operator.

Description

technical field [0001] The invention relates to the technical field of electrostatic grounding, in particular to a high-penetrating electrostatic grounding clip. 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 conduct static electricity on objects. It is usually connected to grounding piles or grounding grids. The clip body is clamped on the object and penetrates the paint, stains or oxide layer on the surface of the object through sharp steel nails. And other insulating layers, so that the static electricity accumulated on the object can be guided away, eliminating potential static electricity hazards. [0003] The electrostatic grounding clamp mainly rel...
