Description
Technical Field
The utility model relates to the technical field of bolts, in particular to a bolt and nut anti-loosening assembly.
Background
Bolts are common parts, and can be widely applied to various occasions needing fastening, and in various equipment and devices such as mechanical devices, piers, iron towers, ships, automobiles, aircrafts and the like, bolts and nuts are frequently used for mutually combining two or more parts. When mechanical equipment runs, mechanical vibration can be inevitably generated, long-term mechanical vibration can lead to bolt shaking and thread abrasion, so that the fastening effect of the bolt is poor, and the stability of the mechanical equipment is affected. For example, in bolts and nuts used for rails or the like for running a railway vehicle, the bolts and nuts may be loosened due to vibrations and impacts occurring during running of the railway vehicle. Currently, the loosening of nuts on bolts is often prevented by periodic maintenance by operators in a torqued manner, which increases the labor cost of the machinery. The novel bolt and nut anti-loosening assembly is designed, anti-loosening can be achieved, and market patterns are enriched.
