Spring with limiting function

Abstract

The invention discloses a spring with a limiting function. The spring comprises a pair of circular plates, and the pair of circular plates are fixedly connected through a telescopic rod. When the spring body is used, dust particles attached to the surface of the spring body can be automatically cleaned, and the situation that the spring body is damaged by the dust particles when compressed due to the fact that the dust particles are accumulated on the surface of the spring body is avoided; dust particles falling on the top of the lower circular plate and located outside the spring body during vibration cleaning can be blown while the spring body is cleaned, the situation that too much dust particles are accumulated on the lower circular plate and finally attached to the bottom of the spring body is avoided, and the cleaning effect is prevented from being affected; dust particles on the impact surface of the spring body and the impact rod can be cleaned while the spring body is vibrated and cleaned, the situation that the impact effect is affected due to the fact that the dust particles are compacted when the impact rod impacts the spring body is avoided, and then the vibration cleaning effect is prevented from being affected.

Description

technical field [0001] The invention belongs to the technical field of springs, and particularly relates to a spring with a limiting function. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] When the spring is in use, in order to prevent the spring from being bent and deformed, a telescopic rod is usually set inside the spring to limit the position of the spring to realize the limit function. The existing spring with the limit function is used in an environment with more dust, impurities and particles. When compressing, dust and impurity particles are prone to atta...

Problems solved by technology

[0003] When the spring is in use, in order to avoid the spring from being bent and deformed, a telescopic rod is usually set inside it to limit the spring to realize the limit function. The existing spring with the limit function is used in an environment with a lot of dust, impurities and particles. When it is used, it is easy to have dust and impurity particles attached to the outside of the spring, causing the accumulation of impurity particles, making the spring prone to be damaged by particles when compressed
