The invention discloses a compression spring, which comprises a spiral body, wherein the middle part of the spiral body is provided with an arched protruded section; arched sunken sections are arranged between the arched protruded section and each end of the spiral body respectively; and cylindrical sections are arranged between each arched sunken section and the corresponding ends of the spiral body respectively. Due to the adoption of the technical scheme, the compression spring can be adapted to large-area and high-pressure external load.
Description
technical field [0001] The invention relates to a compression spring. Background technique [0002] The compression spring is a helical spring that bears the pressure. The cross-section of the material used is mostly circular, and it is also made of rectangular and multi-strand steel coils. The spring is generally of equal pitch. The shapes of the compression spring are: cylindrical, conical Shape, convex and concave, and a small amount of non-circular, etc., to meet the needs of different working conditions. There is a certain gap between the coils of the compression spring. When the external load is applied, the spring shrinks and deforms, storing deformation energy. However, the existing spring shape is not suitable for large area and large pressure external load. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compression spring adaptable to large area and large pressure external load. [0004] In order ...
