Abstract

The invention relates to a chuck device with a self-locking structure. The chuck device comprises a U-shaped rod (6) and a seat (1). The seat (1) is provided with a pair of through holes (5), and after penetrating out of the corresponding through holes (5), the two ends of the U-shaped rod (6) are connected with nuts (4) in threaded fit with the two ends correspondingly. The chuck device is characterized in that an anti-loosening structure is arranged on matched faces between each nut (4) and the seat (1). The chuck device has the beneficial effects that the structure is simple, manufacturing and machining are simple, and loosening of a steel wire rope is further prevented while the nut locking force of the chuck device is improved.

Description

technical field [0001] The invention relates to a wire rope locking device, in particular to a chuck device with a self-locking structure. Background technique [0002] Steel wire ropes are mainly used for hoisting, traction, tensioning and carrying large and heavy machinery and equipment, and are widely used in steel, chemical, transportation, ports and other industries. When the steel wire rope is reinforced and connected, a chuck device is needed, but the existing chuck device has a relatively low locking strength and cannot completely lock the wire rope. Contents of the invention [0003] The object of the present invention is to solve the technical problem of low locking strength of the steel wire rope chuck device in the prior art, and provide a chuck device with a self-locking structure. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A collet device with a self-locking structure, including a U-shaped b...
