Description

Cable tightening device

technical field

The utility model relates to the field of electric tools, in particular to a cable tightening device.

Background technique

It is very important to ensure the safe and stable operation of the power grid in today's society. The cable is erected on the pole or building through the street yard. The fixing of the cable end is generally to bend the cable end around the street yard and bend it in a direction, and bind or fix the separated cables under tension; In general, construction workers usually press the separated cables together by traditional methods such as manpower or simple tools, and then use binding wires to bind and fix the compressed cables. Because the diameter of the cable is relatively thick, it is difficult for workers working at heights to press the cable together only by manpower or simple tools, and the cable itself is very elastic when it is bent, and it is easy to bounce or slip off from the hands or simple tools. the difficulty of construction. The binding wires are generally thin aluminum metal wires. Tightening the cables will reduce the insulation of the cables and easily cause damage to the outer layer of the cable insulation. Moreover, there is no uniform standard for the binding method, which is very random, resulting in the firm binding of the cable ends. It is difficult to guarantee the safety, and the cable end is easy to loosen and fall off from the street yard, which brings safety hazards; although some existing wire tightening devices can basically solve the above problems, they have the following problems: the structure of the wire tensioner is complex Bulky, high processing and manufacturing costs, and the dynamic pressure block is easy to shake relative to the body of the wire tensioner during operation, and the portability and safety of the operation are not good; the cables are crossed after passing around the street yard, and the surface is inclined, tight When the cable device is pressing the cable, it is easy to slip on the cable, which makes it difficult to fix the pressing position; the cable clamp can only lock the cable at one point. If you want to lock the cables that are separated from each other firmly, you need Continuously using two or more clamps to lock the cable within a distance is time-consuming, labor-intensive and expensive.
