Description

Technical Field

[0001] This utility model relates to the field of tension clamp technology, and more specifically, to an adjustable tension clamp. Background Technology

[0002] Tension clamps are hardware used to fix conductors, bear the tension of the conductors, and hang the conductors on tension strings or towers. Based on their structure and installation conditions, tension clamps can be broadly divided into two categories: Category 1: Tension clamps must bear the entire tension of the conductor or lightning protection wire; Category 2: Tension clamps, in addition to bearing the entire tension of the conductor or lightning protection wire, also act as conductors.

[0003] In most cases, existing tension clamps involve inserting the wire into deformable plastic and then inserting the plastic into an aluminum alloy tube. The wire is secured by the inconsistent openings at the top and bottom of the aluminum alloy tube. However, since the deformable plastic does not have a fixing mechanism, it is easy for it to come out of the aluminum alloy tube, affecting the firmness of the fixation.

[0004] Furthermore, tension clamps are often installed in a fixed direction, which means that when the transmission direction of the external cable changes, the clamps need to be disassembled and adjusted, making them cumbersome to use and reducing installation efficiency. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an adjustable tension clamp, which has the following advantages:

[0018] 1. By setting up a first clamping block, an insulating pad, and a threaded post, the user can place the cable to be fixed into the middle position of the first clamping block and the second clamping block, and then tighten the fastening nut to adjust the distance between the insulating pad and the second clamping block so that the inner wall of the insulating pad and the second clamping block abuts against the outer wall of the cable, thereby achieving the effect of fixing the cable. This is convenient to use. When the cable is thin, the threaded post can also be rotated to move the insulating pad downwards to provide a certain pressure to the cable, thereby fixing it more firmly.

[0019] 2. By setting up a hanger, a hanging ring, a ring, and an adjustment hole, the user can suspend the device onto an external utility pole using the hanger. At the same time, the first and second clamping blocks can be rotated by removing the adjustment screws to facilitate the fixing of cables from different directions. After adjustment, the adjustment screws are screwed back into the positioning hole and adjustment hole to achieve fixation, thereby increasing the flexibility of the device during use.

[0020] 3. By setting the first clamp, the second clamp, and the connecting screw, the user can connect the device to the outside world by closing the first clamp and the second clamp. Then, tightening the connecting screw will make the first clamp and the second clamp hold the external support equipment, thereby achieving the effect of fixing the device, which facilitates connection and maintenance.
