Description

Technical Field

[0001] This invention relates to an improvement in cable locking technology, belonging to the field of electrical engineering, and particularly to a cable locking device and its usage method. Background Technology

[0002] During the use of power circuits, if the distance between the stuffing box inside the equipment and the connection point is too long, the cable will vibrate under the action of electric power. In this case, the cable inside the equipment must be fixed. Conventional cable fixing methods generally use cable ties and bolts for fixing. However, in the later maintenance and repair process, cable ties often age and fall off in batches and screws strip, increasing the workload of later maintenance. In order to solve such problems, a simple and practical cable locking mechanism is needed.

[0003] Chinese patent application CN201820747824.9, filed on May 19, 2018, discloses a cable clamp comprising a fixing block, a mounting block, a guide post, a guide sleeve, a locking mechanism, an upper clamping block, a connecting mechanism, and a lower clamping block. The mounting block is fixed to the bottom of the side wall of the fixing block and has a first threaded hole in the middle. The guide post is fixed to the top of the fixing block, and the guide sleeve is slidably connected to the guide post. The locking mechanism is fixed to one end of the top of the guide sleeve for locking the guide sleeve. Both sides of the upper clamping block are connected to the guide sleeve through the connecting mechanism. However, in actual operation, this design is cumbersome, involves many cable fixing steps, and is difficult to operate.
