Description

Technical Field

[0001] The invention relates to the technical field of line detection equipment, and in particular to a self-locking and compressed portable grounding wire that can be quickly disassembled and assembled. Background Art

[0002] When power equipment needs to be shut down for maintenance, in order to ensure the safety of operators, temporary grounding wires need to be installed on each possible power supply side of the power outage maintenance equipment to ensure the personal safety of operators and avoid electric shock when there is residual charge, induced charge or mis-powering.

[0003] The spiral-compressed portable grounding wire is the most common grounding wire, which consists of a wire end clamp, a short-circuit line, a grounding end clamp and an insulating rod. When in use, first connect the grounding end clamp to the grounding flat iron or the grounding end, rotate the wire end clamp jaws counterclockwise to open them, buckle the copper bar to be grounded, and then rotate the insulating rod clockwise to lock the jaws. However, the locking method of the traditional spiral-compressed portable grounding wire does not have a continuous force to keep it locked after the operator leaves. The locking force is too small due to the friction of the thread alone. A slight movement or accidental touch can easily loosen the jaws, causing the clamp to fall off, and the operator loses the safety measure. Therefore, a self-locking and compressed portable grounding wire that can be quickly disassembled and assembled is designed to address this situation. This self-locking and compressed portable grounding wire that can be quickly disassembled and assembled has a large locking force, is relatively firmly fixed, and is easy to disassemble through the cooperation of a card plate, a wedge groove and a spring. It can be better applied to occasions where the operating space is relatively small, thereby ensuring the safety of the operator. Summary of the invention
