Description

Technical Field

[0001] The invention relates to the field of insulating operating rods, in particular to a segmented insulating operating rod with high connection strength for electric power engineering. Background Art

[0002] The insulating operating rod is an insulating tool used in power engineering, which is used for live working and live maintenance. Depending on the use environment, it often needs to be spliced ​​and assembled to obtain sufficient length for use.

[0003] The existing patent (publication number: CN112053864A) discloses a link rod connecting device, including an upper connecting block and a lower connecting block, a threaded block and a fixed block are vertically welded in the middle of the lower end face of the upper connecting block, a plug-in block is provided on the lower end face of the fixed block, and a shell is fixed by a spiral fit on the outer side of the threaded block, a supporting block is horizontally welded on the upper end face of the lower connecting block, a clamping block is welded in the middle of the upper end face of the supporting block, a clamping groove is provided in the middle of the clamping block, and the plug-in block is slidably fitted in the clamping groove of the clamping block, through holes are horizontally provided on both sides of the clamping block, between both sides of the shell and both sides of the plug-in block, and pins are horizontally inserted between the through holes, which can replace the commonly used spiral fixing device, and can better prevent the link rod from axial rotation during long-term use of the link rod, which not only reduces the difficulty of operation, but also reduces the risk factor of falling and injuring people, thereby better meeting people's use needs. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: 1. The Linker rod is connected by a plug-in block, a clamping block and a pin. In actual use and operation, the structural strength is insufficient, and the connection of the Linker rod is very likely to break; 2. The structural rigidity of the Linker rod connection of the device is insufficient, and the strength of the Linker rod connection is only guaranteed by the pin. When multiple Linker rods are used in splicing during actual operation, they are very likely to bend and accidentally fall off, making it impossible for workers to continue electrical operations; 3. The overall structure of the device is complex during the production process, and the strength of structural parts such as the shell, pin, and plug-in block are relatively high. Solving the axial rotation problem of the Linker rod by the above-mentioned mechanism is a complex structure to solve a simple problem, resulting in a high production cost of the device.
