Embodiment 1

[0044] see Figure 2 to Figure 6 As shown, the present embodiment provides a general-purpose push-pull slightly twisted ground wire device, comprising:

[0045] The clamping part 1 includes a fixed claw 101 and a movable claw 102 that can be opened and closed relative to the fixed claw 101;

[0046] The toggle piece 2 is movably connected with the clamping part 1, and the toggle piece 2 can reciprocate and slide along the direction of its own axis to toggle the movable claw 102 to rotate relative to the fixed claw 101 to realize the clamping part 1 Zhang He;

[0047] Specifically: the fixed claw 101 includes a hook portion 1011 and two parallel ribs 1012 integrally formed with the hook portion 1011, the movable claw 102 is pivotally connected between the two parallel ribs 1012, and the movable claw 102 can be Rotate around the pivot to adjust the degree of opening and closing between it and the fixed claw 101, so as to facilitate the clamping of copper wires with different d...

Embodiment 2

[0066] This embodiment provides a general-purpose push-pull micro-twisted grounding wire device, which differs from Embodiment 1 only in that in this embodiment, the movable claw 102 and the pull rod 204 in Embodiment 1 are passed through the rack 205 and the first tooth. The meshing connection of the teeth 103 is replaced by a connecting rod connection between the movable claw 102 and the pull rod 204. Specifically, one end of the connecting rod is hinged at the end of the movable claw 102 near one end of the pivot, and the other end of the connecting rod It is hinged with the top of the pull rod 204, so that the movable claw 102 can also be pivoted by moving the insulating rod up and down.

Abstract

The invention relates to the technical field of power grounding wire clamps, and provides a universal push-pull micro-torsion type grounding wire device, which comprises a clamping part, a poking piece and a locking piece, wherein the clamping part comprises a fixed claw and a movable claw which can be opened and closed relative to the fixed claw; the poking piece is movably connected with the clamping part and can slide in a reciprocating mode in the direction where the axis of the poking piece is located to poke the movable claw to rotate relative to the fixed claw so as to achieve opening and closing of the clamping part; and the locking piece can move back and forth to be close to or far away from the poking piece, so that the locking piece and the poking piece are propped against eachother and separated from each other. The grounding wire can be conveniently and rapidly assembled and disassembled, the clamping stability and the wire clamp anti-falling performance are reliable, and the problems of inconvenient operation, high labor intensity, long time consumption, potential safety hazard and the like generally existing in the process of assembling and disassembling the grounding wire are thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of power grounding wire clips, in particular to a general-purpose push-pull slightly twisted grounding wire device. Background technique [0002] In the power system, the grounding wire is an important tool to lead the current into the earth and ensure the safety of the staff when the voltage appears unexpectedly on the equipment and lines that have been powered off. The installation of grounding wire is an important electrical safety technical measure. [0003] At present, the conductor end clamps of short-circuit grounding wires used in power systems generally adopt two structural forms: screw fastening and double tongue spring fastening. According to the functional structure of each part, they can be divided into wire end clamps, grounding leads, and grounding terminal Clips and insulated operating rods. At this stage, the principle and functional defects of the grounding wire are mainly the wire termin...
