Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a shock-resistant nut structure with a self-locking function. Background Art

[0002] Nuts, also known as nuts, are a common fastener widely used in machinery, construction, automobiles, electronics and other fields; the main function of nuts is to be used in conjunction with bolts or screws to fasten two or more parts. There are many types of nuts, which can be divided into multiple types according to different uses and requirements.

[0003] Traditional nuts, due to the lack of self-locking structure, may cause the nuts to shake after a period of installation or due to factors such as vibration, resulting in the nut's fixation to the bolt becoming loose, thereby reducing the nut's fixing effect and making it impossible for the nut to fix the bolt. The parts or structures fixed by the nut are prone to falling off, making it easy for workers or local residents to be injured, greatly increasing the safety risk of personnel, and loose parts will also affect the progress of work, resulting in reduced work efficiency.

[0004] Therefore, for the above-mentioned traditional nuts, due to the lack of self-locking structure, the nuts will shake after being installed for a period of time or due to factors such as vibration, resulting in the problem of loosening of the nut fixing the bolt. A method can be designed to generate a force through spring compression to lock the nut, reduce the shaking of the nut, and reduce the problem of loosening of the nut fixing the bolt, so that the fixing effect of the nut is guaranteed, so that the nut can fix the bolt, and the parts or structures fixed by the nut are not easy to fall off, preventing workers or local residents from being injured, greatly reducing the safety risks of personnel, and preventing the influence of loose parts on the work process, reducing the reduction in work efficiency.
