A spring assembly with a limiting function

Abstract

The invention provides a spring assembly with the limiting function and belongs to the technical field of mechanical parts. The spring assembly with the limiting function solves the technical problem that the compression distance of a spring in the prior art cannot be limited. The spring assembly with the limiting function comprises a spring, an upper cover plate and a lower cover plate are fixedly connected to the two ends of the spring respectively, a telescopic pull rod mechanism is fixedly connected between the upper cover plate and the lower cover plate and comprises a positioning rod with a cavity, one end of the positioning rod is fixedly connected with the lower cover plate, the other end of the positioning rod is movably connected with a moving rod, the moving rod is inserted into the cavity, the portion, far away from the end inserted into the cavity, of the moving rod is fixedly connected with the upper cover plate, and the positioning rod is longer than the moving rod. According to the spring assembly, the compression distance of the spring can be limited, it is guaranteed that the spring cannot be damaged by torsion and compression, the service life of the spring is prolonged, and the spring can also be applied in the special fields requiring compression limiting.

Description

technical field [0001] The utility model belongs to the technical field of mechanical parts and relates to a spring assembly with a position-limiting function. Background technique [0002] As we all know, a spring is a kind of elastic compressible and resilient parts. The spring has a wide range of uses and is indispensable in almost all walks of life in the mechanical field. But the existing spring does not have the function of compression limit, that is, the existing spring can be pressed to the bottom, and when the spring is compressed to the limit, it is easy to twist, resulting in damage to the spring, and the spring will be scrapped as time goes by. Especially in some specific fields, it is necessary to control the compression distance of the spring, which causes the existing springs to fail to meet this requirement.
