1. Mechanical anti-loosening
Use cotter pins, stop washers and string wire ropes. The mechanical anti-loosening method is more reliable, and it is necessary to use the mechanical anti-loosening method to resist important connections.
2. Riveting and anti-loosening
After tightening, it adopts methods such as punching point, welding, and bonding, so that the thread pair loses the characteristics of the movable pair and the connection becomes a non-detachable connection. The disadvantage of this method is that the bolt can only be used once, and it is very difficult to disassemble, and the bolt pair must be destroyed before it can be disassembled.
3. Structure anti-loosening
The structural anti-loosening does not rely on outside labor, but only on its own structure. The anti-loosening method of the structure is the Tang's thread anti-loosening method, and it is also the best anti-loosening method that has started and achieved the results, but it is not known to most people.
