Self-locking steel wire rope fastener

Abstract

The invention relates to a loading and pulling fastener, belongs to an auxiliary machine or a used device for loading and reinforcing services in transports of trains, automobiles, ships and the like, and particularly relates to a self-locking steel wire rope fastener. The self-locking steel wire rope fastener comprises a steel frame, a steel wire rope sleeve, a fluted disc, teeth and the like, wherein the steel frame is U-shaped, the bottom of the steel frame is provided with a guide hole, a wedge-shaped lock buckle matched with the steel frame is arranged in a hollow body at the upper end of the steel frame, and a guide groove is arranged on the wedge-shaped lock buckle; the fluted disc is arranged on the steel frame through the steel wire rope sleeve; and the teeth are engaged with thefluted disc and arranged on the steel frame through a rotating shaft, safety pins are arranged on the teeth, and the steel frame is provided with holes matched with the safety pins. The self-locking steel wire rope fastener is provided with the tooth anti-loosing safety pins and the steel wire rope guide hole which cannot cause swinging and loosening of a steel wire rope or bending deformation ofthe teeth when the pull is increased and can be repeatedly disassembled and assembled in use.

Description

technical field [0001] The invention relates to a loading and pulling fastener, which belongs to auxiliary machinery or devices used for loading and strengthening operations in transportation such as trains, automobiles, ships, etc., in particular to a self-locking type wire rope fastener. Background technique [0002] In the wire rope fasteners transported by vehicles now, one end of the rope is mostly fixed on the vehicle, and the other end is connected to the fastener, which is inconvenient to use and has a small operating range. In the prior art, the wire rope is fastened by teeth (pawls) meshing with the tooth disc (ratchet) through the return spring, which is easy to loosen during use, especially when the tension of the wire rope is large, it is impossible to ensure that the tension and the wire rope act in a single direction.

AI Technical Summary

Problems solved by technology

[0002] In the wire rope fasteners transported by vehicles, most of the ends of the rope must be fixed on the vehicle, and the other end is connected to the fastener, which is inconvenient to use and has a small working range.

In the prior art, the wire rope is fastened by teeth (pawls) meshing with the tooth disc (ratchet) through the return spring, which is easy to loosen during use, especially when the tension of the wire rope is large, it is impossible to ensure that the tension and the wire rope act in a single direction. In a straight line, if the fastening strength required by the goods is high, or when the vehicle shakes during transportation and the tension of the wire rope increases and swings, it is particularly easy to cause the teeth (pawls) to loosen and deform, and cannot continue to play a positioning role, causing the wire rope Loose, loose goods, none of the current fasteners can solve such safety problems

In addition, the existing wire rope fasteners are generally disposable and cannot be reused many times, or are complicated to install and disassemble during use.
