[0001] The utility model relates to the field of power cables, and particularly relates to a power cable installation device. Background Art

[0002] Power cables can be divided into various types according to different classification criteria. According to the voltage level, there are low-voltage cables, medium-voltage cables, high-voltage cables, and extra-high-voltage and ultra-high-voltage cables. According to the insulating material, power cables mainly include plastic-insulated cables, oil-impregnated paper-insulated cables, and rubber-insulated cables, etc. Among them, plastic-insulated cables have gradually become the mainstream products in the market due to their simple structure, convenient manufacturing and processing, and light weight. Installation devices are used during the installation of power cables.

[0003] However, in the prior art, the installation angle of the power cable installation device is fixed. When it is necessary to change the cable's direction, it can only be achieved by bending the cable itself, which will undoubtedly reduce the service life of the cable. Content of the Utility Model

[0008] Preferably, the threaded sleeve is movably connected to the support ring through the rotating shaft.

[0009] Through the above solution, the following technical effects can be achieved: The angle of the wire pressing ring can be adjusted through components such as the swivel ring, short rod, threaded column, threaded sleeve, and rotating shaft, thereby changing the direction of the cable. Compared with traditional adjustment methods, this method is more convenient and can also extend the service life of the cable.

[0010] Preferably, the external thread of the bolt is adapted to the internal thread of the wire pressing ring.

[0011] Preferably, the number of the telescopic rods is two groups, and they are symmetrically arranged about the midline of the connecting block.

[0012] Through the above solution, the following technical effects can be achieved: The height of the wire pressing ring can be adjusted through components such as the fixing bolt, telescopic rod, spring, and adjusting rod, thereby meeting different usage requirements and improving the flexibility of operation.

[0013] Adopting the above technical solution, by rotating the rotating shaft, the rotating shaft drives the threaded sleeve to rotate. Under the cooperation of the external thread of the threaded column, the threaded sleeve slides out from the inside of the limiting groove, releasing the limit on the swivel ring. Rotate the swivel ring, and the swivel ring drives the wire pressing ring to rotate. When it rotates to the appropriate position, rotate the rotating shaft in the reverse direction, and the threaded sleeve enters another group of limiting grooves to complete the limit on the swivel ring, that is, to fix the angle of the wire pressing ring. The angle of the wire pressing ring can be adjusted through components such as the swivel ring, short rod, threaded column, threaded sleeve, and rotating shaft, thereby changing the direction of the cable. Compared with traditional adjustment methods, this method is more convenient and can also extend the service life of the cable.

[0014] Adopting the above technical solution, by rotating the fixing bolt and pushing the telescopic rod, the telescopic rod compresses the spring and slides out from the clamping hole. Pull the adjusting rod upward, and the adjusting rod drives the connecting block to slide inside the connecting rod. When the telescopic rod reaches the position of another group of clamping holes, the spring rebounds to make the telescopic rod enter another group of clamping holes to realize the limit on the connecting block. Rotate the fixing bolt in the reverse direction, and one end of the fixing bolt abuts against one side of the adjusting rod to complete the secondary fixation of the adjusting rod, that is, to realize the elevation of the wire pressing ring. The height of the wire pressing ring can be adjusted through components such as the fixing bolt, telescopic rod, spring, and adjusting rod, thereby meeting different usage requirements and improving the flexibility of operation.
