Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a spring with an overload limiting function. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. It's usually made of spring steel and has the property of elastic deformation, allowing it to deform when subjected to force and return to its original shape when the force is removed. There are many types of springs, such as coil springs, leaf springs, and disc springs, and they are widely used in various fields.

[0003] In the elastic work of springs, most springs themselves do not have an overload protection function. Therefore, when the spring is working, the staff will use different objects to adjust the contraction distance of the spring to limit the work. However, this method cannot be adjusted according to the actual pressure exerted on the spring in different usage environments, resulting in the spring's effectiveness being reduced after long-term use. For this reason, we have proposed a spring with an overload limit function. Utility Model Content
