Especially in winter, rainy days, etc., the performance is more prominent. Thereby greatly increasing the operating time and reducing the power supply reliability.

Utility model content

The technical problem to be solved by the utility model is to provide a plug-in insulating operating rod, which shortens the time for connecting the insulating rod during operation and improves the reliability of power supply.

In order to solve the above technical problems, the utility model adopts the following technical scheme: a plug-in insulating operating rod, including a cylindrical upper joint and a lower joint, the upper joint is a stepped cylinder with a large diameter at the upper end and a small diameter at the lower end. The lower joint is straight cylindrical, and the upper part of the lower joint is provided with an expansion joint. The upper end of the upper joint is connected to the upper insulating operating rod, and the lower end of the lower joint is connected to the lower insulating operating rod. The inside of the upper end of the lower joint is pressed tightly by the wrench on both sides of the expansion joint.

Preferably, a spring is sleeved on the small diameter portion of the upper joint, and the spring is pressed between the upper end face of the lower joint and the stepped end face of the large diameter portion of the upper joint, the wrench includes a pressing plate, and a pressing plate seat is provided on the lower joint Hinged with the tail of the pressure plate, the upper joint is provided with a hook, the head of the pressure plate is provided with a hook ring, and the middle of the pressure plate is provided with a circular arc plate-shaped pressure head.

Preferably, the head of the pressing plate is provided with a U-shaped groove, the shackle is in a "convex" shape, and the convex part of the shackle is hinged in the U-shaped groove.

Preferably, the inner wall of the upper half of the lower joint is provided with helically coiled friction lines.

The utility model improves the connecting head of the insulating operating rod into a plug-in structure, which greatly shortens the manpower and time spent on connecting the operating rods. After using the insulating operating rod, the average time spent on connecting four insulating rods is reduced from the original two people to three. Minutes are shortened to one minute per person, labor costs are saved by 1/2, and the time for connecting insulating operating rods is shortened by 2/3. Calculated by saving 2 minutes for one operation, 100 operations can save 200 minutes, thus greatly improving the reliability of power supply.

Detailed ways

The structure of the plug-in insulating operating rod of the present invention is described below in conjunction with Fig. 1 to Fig. 3, which includes a cylindrical upper joint 1 and a lower joint 2, and the upper joint 1 is a ladder with a large diameter at the upper end and a small diameter at the lower end The lower joint 2 is straight cylindrical, and the upper half of the lower joint 2 is provided with expansion joints 20. Two expansion joints 20 are provided and arranged at intervals of 180 degrees upward around the lower joint 2. The upper end of the upper joint 1 is connected to The upper insulating operating rod, the lower end of the lower joint 2 is connected to the lower insulating operating rod, the small diameter part 11 of the lower end of the upper joint 1 is inserted into the upper end of the lower joint 2 and pressed by the wrench on both sides of the expansion joint 20 . The small diameter part 11 of the upper joint 1 is sleeved with a spring 12, and the spring 12 is pressed between the upper end surface of the lower joint 2 and the stepped end face of the large diameter part 10 of the upper joint 1. The wrench includes a pressing plate 22, and the lower joint 2 is provided with a pressure plate seat 21 hinged with the tail of the pressure plate, the upper joint 1 is provided with a hook 13, the head of the pressure plate 22 is provided with a hook ring 23, and the middle of the pressure plate 22 is provided with an arc-shaped pressure head 24 . The head of the pressing plate 22 is provided with a U-shaped groove 220, and the shackle 23 is in a "convex" shape, and the convex part of the shackle 23 is hinged in the U-shaped groove. The inner wall of the upper half of the lower joint 2 is provided with spirally coiled friction lines to increase friction.

In the utility model, when the upper joint 1 and the lower joint 2 are docked, the small-diameter part 11 at the lower end of the upper joint 1 is inserted into the upper end of the lower joint 2, at this time the spring 12 is compressed, and then the pressure plate 22 is pulled to make the shackle 23 buckle into the hook 13. During this process, the pressure head 24 presses the lower joint 2, and the lower joint 2 presses and fixes the small diameter portion 11 of the upper joint 1 at the same time. Therefore, through the plug-in structure of the upper joint 1 and the lower joint 2, the convenient plug-and-play of the insulating operating rod is realized, without the time-consuming and laborious screw-tightening method.

The plug-in insulating operating rod of the utility model shortens the time for connecting the insulating rod during operation, and improves the reliability of power supply. Through the use of the utility model, it is solved that (1) two people need to cooperate to connect the insulating operating rod when connecting the third and fourth joints; (2) the time required for connecting the insulating operating rod is shortened, and the reliability of power supply is improved.
