Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 4, an embodiment of the present invention discloses an insulated operating rod, which includes: the handle comprises a sleeve 10, a hook body 20, a cylinder body 50, a handle 40, a transmission mechanism 30, a hexagonal sleeve 60 and a handle 70.

The cylinder 50 is fixed at the head of the sleeve 10, and the wall of the cylinder 50 is provided with a gap 51; the hook 20 is disposed in the cylinder 50 and is installed in the cylinder 50 by the core shaft 34, such that the hook 20 can radially extend out of the cylinder 50 through the notch 51 by rotation and can radially retract into the cylinder 50 by reverse rotation.

The end of the sleeve 10 is formed with a plugging portion 11, and the handle 40 has a stud which extends into the plugging portion 11 and is in threaded connection with the plugging portion 11.

The transmission mechanism 30 includes a rotary rod 31, a worm wheel 32 and a worm 33; the rotating rod 31 is arranged in the sleeve 10, the tail part of the rotating rod 31 is inserted into the jack of the stud and is fixed with the stud by means of a jackscrew which radially penetrates through the stud, and thus, the rotating handle 40 can drive the rotating rod 31 to rotate; the worm wheel 32 is arranged at the head of the rotating rod 31 and is positioned in the cylinder 50; the worm 33 is sleeved on the core shaft 34 and forms a transmission fit with the worm wheel 32, so that when the handle 40 is rotated, the hook 20 can be driven to rotate by the cooperation of the rotating rod 31, the worm wheel 32 and the worm 33, and the hook 20 extends out of the barrel 50 or retracts into the barrel 50.

A bearing housing 52 is further formed inside the junction of the cylinder 50 and the sleeve 10, and it is easily understood that the rotary rod 31 is inserted through the bearing housing 52, and a bearing 521 is provided between the rotary rod 31 and the bearing housing 52 for supporting the rotary rod 31.

A hexagonal sleeve 60 is fixed at the head of the cylinder 50, and the hexagonal sleeve 60 is used for screwing a bolt on the electrified equipment; at the rear of the barrel 50 is provided a handle 70, the handle 70 having a radial extension to facilitate the application of force to the bolt by the hexagonal socket 60 by rotating the handle 70.

When the electrical equipment needs to be operated by using the hook body 20, firstly, the handle 40 is rotated to enable the hook body 20 to be accommodated in the cylinder 50 so that the head of the insulated operating rod can extend to the vicinity of an object to be operated, after the head of the insulated operating rod extends to the vicinity of the object, the handle 40 is reversely screwed to enable the hook body 20 to radially extend, and then the operation on the object is carried out; after the operation is finished, the handle 40 is screwed again to retract the hook body 20 in the cylinder body 50, so that the insulating operation rod can be conveniently withdrawn.
