Embodiment 1）

[0026] like Figure 2 to Figure 6As shown, the short-circuit grounding device with better safety and stable structure in this embodiment is a clutch-rotating short-circuit grounding device, which includes a wire end clamp A and a handle 7 . The wire end clamp A includes a pair of splints 1 connected to the steering shaft by means of a support piece 11 and an arc-shaped bite 2 is provided on the upper part. A spring is wound around the rotating shaft 12 of the support piece 11 . Both ends of the spring are against the inner sidewalls of the two splints 1 . The pair module 3 is provided at the end of the wire terminal clamp A. A movable nut 4 is provided in the module 3 . The movable nut 4 is connected with the movable piece 5 arranged on the pair module 3 through a screw. The movable nut 4 can rotate laterally along the screw rod. Movable piece 5 can slide on module 3. The telescopic mechanism 6 includes a pair of telescopic rods 6.1, a cover cylinder 6.2, a guide cylinde...

Embodiment 2）

[0030] Such as Figure 7 to Figure 8 As shown, the difference from Embodiment 1 is that: the inner side wall of the splint 1 is also provided with a depressing tongue 13 , and the depressing tongue 13 is arranged between the rotating shaft 12 and the arc-shaped bite 2 . The other splint 1 is correspondingly provided with a tongue-pressing through hole. The function of the depressing tongue 13 is: when the wire end clamp A is in the open state, the depressing tongue 13 is used to resist the wire end clamp A, so as to avoid the force of the spring to make the telescopic rod 6.1 move back. When it is necessary to loosen the splint 1 for clamping, the pressing tongue 13 contacts the wire, and the wire end clamp A can be released. The remaining technical principles are the same as in Embodiment 1.

Embodiment 3）

[0032] The difference from Embodiment 1 is that the telescopic rod 6.1, the rotating rod 6.4, and the grip rotating rod 7.3 are all threaded, and the rest of the operation methods are the same as in Embodiment 1.

Abstract

The invention discloses a high-safety and stable-structure short circuit grounding device which comprises a lead end wire clamp and a holding rod. The lead end wire clamp comprises a pair of clamping plates which are rotatably connected with the help of a rotating shaft and provided with arc-shaped meshing portions on the upper portions, a pair die block is arranged at the tail of the lead end wire clamp, a moving nut is arranged in the pair die block and movably connected with the same and can transversely rotate and slide in the same, an extensible mechanism is fixedly connected with the moving nut and connected with the holding rod, and a control mechanism capable of controlling the extensible mechanism to extend and contract is arranged on the holding rod. The high-safety and stable-structure short circuit grounding device has the advantages that high safety is realized, and the lead end wire clamp is manually controlled to clamp or release a lead, so that automatic shedding of the lead end wire clamp is avoided.

Description

[0001] The present invention is a divisional application of the invention patent application with the application number 201210548585.1, the application date is December 18, 2012, and the invention name is "clutch rotation type short-circuit grounding device". technical field [0002] The invention relates to a safety tool or appliance for overhauling electric power. Specifically, it relates to a clutch rotating type short-circuit grounding device. Background technique [0003] In existing short-circuit grounding devices, such as figure 1 The grounding wire 100 shown is a safety tool used to temporarily ground the power equipment that has been powered off when the power equipment is overhauled. The induced electric impact generated to prevent the occurrence of electric shock accidents for staff. The installation of grounding wire is a necessary safety technical measure to change the power equipment from the running state to the maintenance state. The grounding wire 100 is...
