Description

Technical Field

[0001] The utility model provides a cable fixing wire clamp used for power transmission and transformation construction, and relates to the technical field of cable fixing. Background Art

[0002] Power transmission and transformation refers to the project of regulating and transforming the electric energy generated by power plants through substations and sending it to user terminals through transmission lines. It plays a key role in ensuring power supply and meeting user needs. In addition, the stability of the cable must be ensured during the construction of power transmission and transformation. The cable fixing clamp is a device specially used to fix and protect the cable. It can prevent the cable from displacement or even damage due to vibration or other external forces.

[0003] In the prior art, the cable fixing clamp uses two arc-shaped pipe grooves and is fixed up and down with bolts. It is usually made of durable materials, has good insulation properties, can directly contact the outer sheath of the cable, and will not generate eddy current loss, thereby improving the power transmission capacity. However, when selecting the existing cable fixing clamp, the diameter of the cable and the required fixing force must be considered. Cables of different diameter ranges must use cable fixing clamps of different specifications. Therefore, the applicability of the existing cable fixing clamps is not high. In view of the shortcomings of the prior art, we propose a cable fixing clamp for power transmission and transformation construction. Utility Model Content

[0006] Preferably, the sliding bin is a rectangular bin body with an opening on one side, the clamps are longitudinally arranged in two groups and gaps are provided between the clamps, circular shafts are symmetrically provided in the clamps and the sliding bin, and the connecting rod assembly is rotatably provided on the circular shaft.

[0007] Preferably, the connecting rod assembly is a scissors-type telescopic frame, which is rotatably arranged between the clamping plate and the sliding bin, and includes a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, and the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod are rotatably connected to each other in pairs, and a fifth connecting rod and a sixth connecting rod are rotatably connected at the hinge points between the first connecting rod and the second connecting rod, and the third connecting rod and the fourth connecting rod, and the other end of the fifth connecting rod is connected to the third connecting rod, and the other end of the sixth connecting rod is connected to the second connecting rod.

[0010] Beneficial effects of the utility model:

[0011] By setting the telescopic components, the symmetrically arranged telescopic components drive the sliding of the two groups of semi-positioning grooves and control the distance between the two groups of semi-positioning grooves, so that cables of different diameters can be placed, avoiding the need to carry cable fixing clamps of different specifications when installing cables of different diameters, thereby increasing the applicability of the cable fixing clamps. At the same time, by setting the spring and the arc-shaped pad, the spring is compressed during fixation, so that the arc-shaped pad can better fit the outer surface of the cable, thereby avoiding the loosening of the cable.
