Description

Technical Field

[0001] The invention relates to the technical field of leaky cable clamps, in particular to a telescopic and length-adjustable leaky cable clamp. Background Art

[0002] There are periodic slots distributed on the outer conductor of the leaky cable, and the electromagnetic wave signal radiates outward from the slots. In engineering applications, the leaky cable needs to be fixed with a leaky cable clamp. One end of the hanging leaky cable clamp is clamped on the steel strand, and the other end fixes the leaky cable. The existing leaky cable hanging clamp includes a hanging steel strand end and a fixed leaky cable end. The distance between the center of the fixed leaky cable end and the center of the hanging leaky cable steel strand end is a fixed value. During actual assembly, the steel strand will have a height deviation during assembly, which will cause the leaky cable to have a height deviation, which will lead to the leaky cable being unable to ensure that it is at the same horizontal height during the entire installation. The continuous deviation is likely to cause the leaky cable installation height to not meet the standard, resulting in deviations in the signal transmission of the leaky cable. For this reason, it is urgent to develop a leaky cable clamp that can adjust the telescopic length. Summary of the invention

[0044] Its working principle is as follows: the clamping of the steel strand only requires a first fastening bolt to be tightened horizontally, and the fixing of the leaky cable only requires the leaky cable to be inserted into the clamping area through the notch adjustment area, and then the locking hook is flipped so that the locking end of the locking hook is embedded in the inner cavity of the locking positioning hook. In addition, since the steel strand fixing mechanism and the leaky cable fixing mechanism are connected by adjusting the stud assembly, the ball head structure of the stud structure is embedded in the ball head mounting cavity, and lubricating oil is injected into the ball head mounting cavity. The ball head structure is smooth as a whole, and the stud structure can rotate normally and reliably without wearing the ball head mounting cavity. The upper thread of the connecting stud is connected to the threaded positioning hole, and the depth of the connecting stud inserted into the threaded positioning hole is adjusted and set according to the horizontal height requirement of the leaky cable, which makes the center position between the fixed leaky cable and the fixed steel strand adjustable, ensures that the leaky cable can be adjusted for error in the height direction, makes the horizontal reliability of the leaky cable good, and ensures stable and reliable signal transmission of the leaky cable.
