Description
Technical field
The utility model belongs to mechanical field, and in particular to a kind of self-locking nut.
Background technology
Nut is exactly nut, is threaded together the part for playing the role of fastening, all manufacturing machines with bolt or screw rod
Tool must a kind of element according to the difference of material, be divided into several big types such as carbon steel, stainless steel, non-ferrous metal (such as copper).
But the nut due to commonly using does not have locking functions, therefore nut is easy to the situation for occurring loosening or losing.Spiral shell
Female loosening or loss sometimes can also bring great potential safety hazard, the such as nut on Along Railway, once lose or loosen,
Then can cause a significant threat to the people's lives and property.In order to avoid the generation of accident, railway worker will periodically overhaul nut
Locking situation, although so reducing the occurrence probability of accident, but significantly increase the workload of railway worker.
