Problems solved by technology

Once you encounter the situation where you need to adjust the free height or stiffness coefficient of the spring, you can only choose to replace the new spring or achieve it through the combination of springs, so it is quite inconvenient to use.

Abstract

The invention discloses a multilayer buffer spring which comprises an inner spring, a middle spring and an outer spring. The middle spring is mounted inside the outer spring, the inner spring is mounted inside the middle spring, a fixing rod is mounted inside the inner spring, the height of the middle spring is twice that of the outer spring, the height of the inner spring is three times that of the outer spring, the diameter of the inner spring is smaller than that of the middle spring, the diameter of the middle spring is smaller than that of the outer spring, the bottoms of the inner spring, the middle spring and the outer spring are positioned on the same horizontal plane, and the centers of the fixing rod, the inner spring, the middle spring and the outer spring are positioned on the same straight line. The multilayer buffer spring is simple in structure and has high economic benefits and wide application prospects, the free height and stiffness coefficient can be adjusted, a fastening component applies pressure to one peripheral side of the outer spring to increase friction force between a cavity and the inner spring, and positional fixity of the inner spring and the outer spring is ensured.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a multi-layer buffer spring. Background technique [0002] At present, a spring is a freely expandable elastic member, which is often used in the fields of shock absorption, clamping, energy storage and measurement, and is closely related to our production and life. There are many types of springs, basically including the following types: compression springs, extension springs, torsion springs and flat scroll springs. Although the functions of the above-mentioned springs are different, there is one thing in common, that is, their free height and stiffness coefficient are fixed. Once you encounter the situation that you need to adjust the free height or stiffness coefficient of the spring, you can only choose to replace it with a new spring or realize it through the combination of springs, so it is quite inconvenient to use. Contents of the invention [0003] The purpose of th...
