Background

The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and consists of the steel wires, a rope core and lubricating grease. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. The steel wire rope has the characteristics of high strength, light dead weight, stable work, difficulty in breaking the whole steel wire rope suddenly, reliability in work and the like, and is mainly used for lifting, traction, tensioning and bearing in material handling machinery. At present, the wire rope is generally matched with a wire locking structure when in use, so that the length of the wire rope can be freely adjusted by personnel conveniently.

However, the traditional steel wire rope locking structure is only locked by a built-in steel ball, and the steel wire rope cannot rotate freely relative to the locking structure after being locked, so that the use range of the locking structure is limited, the use requirements of different scenes are difficult to meet, the abrasion between the steel wire rope and the locking structure is very serious when an object lifted, pulled, tensioned or borne swings, and the service lives of the locking structure and the steel wire rope are inevitably shortened.

Therefore, it is necessary to design a wire locking structure of the steel wire rope.
