Description

Technical Field

[0001] This utility model relates to the field of tension clamp technology, specifically to a self-locking tension clamp. Background Technology

[0002] Tension clamps are a common auxiliary hardware in high-voltage power distribution lines. In these lines, they are used to fix overhead insulated aluminum conductors to insulators on corner or terminal tension poles, thereby securing or tightening the conductors. Insulating covers are used in conjunction with tension clamps to provide insulation and protection. They are hardware used to fix the conductors, withstand conductor tension, and hang them onto tension strings or towers. Currently, the most commonly used tension clamps are bolt-type and wedge-type.

[0003] Ordinary wedge-shaped tension clamps do not have a self-locking function. During installation and disassembly, a large number of bolts need to be manually turned to fix the clamps. This results in low assembly efficiency, weak clamping performance, and easy movement of cables, which can damage them. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a self-locking tension clamp, which can effectively solve the problems of the existing technology requiring manual twisting of a large number of bolts to fix the components during installation and disassembly, resulting in low assembly efficiency, weak clamping performance, and easy cable movement and damage.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a self-locking tension clamp, including a clamping plate, a movable plate disposed within the clamping plate, and a clamping plate disposed on the outer side of the end of the movable plate. A positioning groove is formed in the middle of the clamping plate, and sliders are fixed on both side walls of the positioning groove. The movable plate is inserted and fixed in the positioning groove. Sliding grooves are formed on both outer side walls of the movable plate, and the sliders are engaged in the sliding grooves. An arc-shaped groove is formed through the top of the movable plate, and the clamping plate includes a clamping frame and a fastening bolt disposed on the top of the clamping frame. The clamping frame is sleeved on the outer side of the end of the movable plate.

[0009] Furthermore, the positioning groove is a combination groove structure with an arc-shaped top and a square bottom.

[0010] Furthermore, the movable plate is an inverted right-angled trapezoidal structure, and the sliding groove is inclined on both sides of the bottom end of the movable plate.

[0011] Furthermore, the clamping frame is a hollow frame structure without sides, and the inner top of the clamping frame is an arc-shaped structure.

[0012] Furthermore, the clamp plate has multiple sets of weight-reduction holes.

[0013] Furthermore, a circular hole is provided at the top of the clamping frame, and a fastening nut is fixed at the top of the clamping frame. The fastening bolt engages with the fastening nut and is fixed, with its bottom end penetrating through the circular hole.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0016] This utility model, through its clamping plate and movable plate structure, allows users to use the movable plate structure with a sliding groove to engage with the clamping plate equipped with a slider. The inclined movable plate structure can be adjusted according to different cable sizes. The inner movable plate can move outwards, and the hollow structure formed by the inner arc-shaped groove structure and the positioning groove of the clamping plate can gradually decrease in size, thus making it suitable for cables of different diameters for secure engagement. Furthermore, the clamping plate structure can be secured inwards within the clamping frame using fastening bolts to fix the cable in place, thus fixing the cable to the clamp. This design is suitable for on-site installation operations. Attached Figure Description
