Description

TECHNICAL FIELD

[0001] The utility model belongs to compression spring technical field, concretely relates to a variable cross section anti-deformation compression spring. BACKGROUND

[0002] Compression spring, also known as compression spring, is a kind of helical spring that bears axial pressure. Its material section is mostly circular, but also rectangular and multi-strand steel winding. Compression spring is generally equal pitch, various shapes, including cylindrical, conical, convex, concave and a small amount of non-circular etc. There is a certain gap between the coils of these springs, when subjected to external load, the spring will shrink and deform, and store deformation energy.

[0003] Variable cross section compression spring refers to a kind of compression spring whose cross section shape changes at different positions of the spring. The design of this spring makes it have different cross section size and shape at different positions, so as to provide more complex mechanical properties and adaptability in application.

[0004] After compression spring is stressed, the spring will not only move downward, but also bend to both sides when the two sides of the spring are not limited, which causes the anti-deformation ability of the spring to decline and affects the performance of the compression spring.
