Self-locking compression type portable grounding wire capable of being disassembled and assembled quickly

Abstract

The invention discloses a self-locking compression type portable grounding wire capable of being assembled and disassembled quickly, which comprises an upper clamping plate, a lower clamping plate, avertical clamping plate, a movable clamping plate, a supporting rod, a fixed clamping piece, a movable clamping piece, a round rod and an insulating rod, and is characterized in that one end of the upper clamping plate is connected with the upper end of the vertical clamping plate, one end of the lower clamping plate is connected with the lower end of the vertical clamping plate, one end of the supporting rod is connected with one end of the insulating rod, a first round hole is formed in the lower clamping plate, the other end of the supporting rod penetrates through the first round hole andextends out of the first round hole, the movable clamping plate is arranged at the end, which extends out of the first round hole, of the supporting rod, a wedge-shaped groove is formed in the supporting rod, a cavity is formed in the lower clamping plate, the fixed clamping piece is arranged on the side, which is close to the vertical clamping plate, in the cavity, the movable clamping piece is arranged on the side, which is away from the vertical clamping plate, in the cavity, a spring is arranged at the end, which is away from the vertical clamping plate, of the movable clamping piece, theother end of the spring is connected with the lower clamping plate, a clamping plate is arranged at the end, which is close to the vertical clamping plate, of the movable clamping piece and matched with the wedge-shaped groove.

Description

technical field [0001] The invention relates to the technical field of line detection equipment, in particular to a self-locking and compacting portable grounding wire that can be quickly disassembled and assembled. Background technique [0002] When power equipment needs power outage maintenance, in order to ensure the safety of operators, it is necessary to install temporary grounding wires on each possible incoming power side of the power outage maintenance equipment to ensure that operators are protected when there is residual charge, induced charge, or wrong power transmission. Personal safety, avoid electric shock, [0003] The spiral compression portable grounding wire is the most common type of grounding wire. It consists of a wire end clamp, a short circuit wire, a grounding end clamp and an insulating rod; Rotate the jaws of the terminal clamp counterclockwise to open, buckle the copper bar that needs to be grounded, and then turn the insulation rod clockwise to l...

[0003] The spiral compression portable grounding wire is the most common type of grounding wire. It consists of a wire end clamp, a short circuit wire, a grounding end clamp and an insulating rod; Rotate the jaws of the terminal clamp counterclockwise to open, buckle the copper bar that needs to be grounded, and then turn the insulation rod clockwise to lock the jaws. The force keeps it locked, and the friction force of the thread alone causes the locking force to be too small. A little movement or accidental contact will easily loosen the jaws, the clamp wil
