Description

Spring with adjustable length

Technical Field

The utility model relates to a spring, in particular to spring of adjustable length belongs to spring technical field.

Background

A spring is a mechanical part that works by elasticity. The part made of elastic material deforms under the action of external force and restores to the original shape after the external force is removed. Typically made of spring steel. The kind of spring is complicated various, including compression spring, and compression spring (pressure spring) is the coil spring who bears axial pressure, and the spring generally divide into equal pitch spring and variable pitch spring, and compression spring's shape has: the compression spring is cylindrical, conical, convex and concave, and a small number of non-circular shapes, and the like, a certain gap is reserved between the rings of the compression spring, and the compression spring contracts and deforms when subjected to external load, so that deformation energy is stored. Variable pitch springs are more and more popular, and instead of being just equal pitch springs, variable pitch springs can play different roles in different environments. Although current pneumatic height-adjusting seat can come height-adjusting through the pneumatic valve, it is not ideal to use the gas pole to carry out the shock attenuation effect alone, and in case the risk that the gas pole has the damage when too big use of pressure, if use the spring to assist the shock attenuation limitation great, when pneumatic valve control seat reduces, spring compression elasticity is too big, when pneumatic valve control seat rises, the spring extends elasticity and descends, uses comparatively inconveniently.
