Technical Field

[0001] This utility model belongs to the field of helical springs, and specifically relates to an anti-deviation helical spring. Background Technology

[0002] Coil springs have always been a primary load-bearing component in passenger vehicles, supporting a large portion of the vehicle's weight. They are made from spring steel bars and have traditionally been designed with equal pitch, meaning the gap between the coils is equal. However, with the development of the coil spring and automotive industries, coil springs are no longer limited to passenger vehicles but are becoming increasingly common in commercial vehicles. Commercial vehicles, due to their cargo-carrying function, often require coil springs before loading, and the load on the vehicle changes significantly after loading. In current technology, coil springs need to be packaged and transported after production. How to prevent the coil section from shifting during packaging and transportation has become a pressing technical problem that needs to be solved.

[0003] This invention attempts to mitigate or at least alleviate such problems or defects by providing new or otherwise improved helical springs. Utility Model Content

[0009] An external baffle plate, which can pass through the positioning screw, abuts against the outer wall of the spiral segment.

[0010] As a further improvement of this utility model, a hook protective sleeve can be removably fitted onto the hook section, and the hook protective sleeve can cover the hook section, with the diameter of the hook protective sleeve matching the diameter of the hook section.

[0011] As a further improvement of this utility model, a hook protective sleeve can be removably fitted onto the hook section, and the hook protective sleeve can cover the hook section, with the diameter of the hook protective sleeve matching the diameter of the hook section.

[0012] As a further improvement of this utility model, a built-in abutment pad can be detachably installed on the built-in baffle plate, and the diameter of the built-in abutment pad is adapted to the diameter of the built-in baffle plate.

[0013] As a further improvement of this utility model, an external contact pad can be detachably installed on the external baffle plate, and the diameter of the external contact pad is compatible with the diameter of the external baffle plate.
