Description

High-strength connecting check bolt

Technical Field

The utility model belongs to the technical field of bolts, and particularly relates to a high-strength connecting check bolt.

Background

Threaded connections are the most basic connection means in a variety of mechanical devices and are also the most common connection parts. However, the screw connection is often loosened due to mechanical vibration and the like, so that the machine is in fault, and even serious casualties are caused. The basic principle of the locking of the threaded fastener is that the threads are prevented from rotating relatively because of the relative rotation of the threads.

At present, the thread anti-loosening method which is more commonly used at present mainly comprises friction anti-loosening, mechanical anti-loosening and thread pair damage anti-loosening. The reliability of friction looseness prevention is poor, and risks are more likely to occur particularly under the working conditions of larger vibration, impact and load. The mechanical looseness prevention is realized by using a groove-shaped nut, a cotter pin, a round nut, a stop washer, a series steel wire and the like. However, the anti-loosening method has the defects of difficult installation and disassembly, more obvious defect of loosening prevention of the broken thread pair, and the bolt can be used once, so that the utilization rate of materials is greatly reduced, and the installation and the disassembly are very difficult.
