Description

Technical Field

[0001] The utility model belongs to the technical field of spring shock absorbers, and in particular relates to a spring shock absorber with high stability. Background Art

[0002] Spring shock absorber is an elastic support element specially designed to reduce or eliminate the vibration and impact caused by the operation or external influences (such as periodic vibration or instantaneous impact caused by wind, steam hammer and earthquake, etc.), which can achieve this function through damping, initial force stiffness and spring pre-compression. Spring shock absorber can increase the natural vibration frequency of the whole equipment, separate the forced vibration frequency caused by external interference, and thus prevent the machine from resonating.

[0003] At present, most of the spring shock absorbers widely used in the market adopt the design of a single spring directly mounted on the piston rod. This structure limits the support and buffering effect of the shock absorber on the object to be damped to a certain extent. Due to the direct contact between the spring and the piston rod, the shock absorbing effect may not be ideal and cannot fully absorb and disperse the vibration energy, thus affecting the stability and safety of the object to be damped. In addition, due to the close combination of the spring and the piston rod, the disassembly and installation process is relatively cumbersome, which not only increases the labor intensity and operation difficulty, but also may affect the maintenance efficiency.
