Embodiment 1）

[0026] Such as Figure 2 to Figure 6As shown, the conveniently operated and short-stroke clutch rotating short-circuit grounding device of this embodiment 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 cylinder 6.3, a rotating rod 6.4, and a side cyl...

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 an engagement and disengagement rotary type short circuit grounding device convenient to operate and short in stroke. The device comprises a wire end cable clamp and a holding rod, the wire end cable clamp comprises a pair of clamping boards which are rotationally connected through a rotary shaft, arc occlusions are arranged on the upper portions of the clamping boards, and the tail portion of the wire end cable clamp is provided with a pair module. The pair module is provided with a movable nut movably connected with the pair module, and the movable nut can transversely rotate and slide in the pair module. A telescopic mechanism is fixedly connected with the movable nut and connected with the holding rod. The holding rod is provided with an operation mechanism capable of operating the telescopic mechanism to stretch and retract. The engagement and disengagement rotary type short circuit grounding device convenient to operate and short in stroke has the advantages that safety performance is high, the wire end cable clamp is manually controlled to clamp or release wires, and therefore the situation that the wire end cable clamp automatically falls off 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...
