[0001] The utility model relates to the technical field of shock-absorbing bushing components, in particular to a combined shock-absorbing bushing component. Background Art

[0002] As an important mechanical component, the combined shock-absorbing bushing assembly plays a key role in multiple fields and scenarios. In various mechanical equipment, such as compressors, pumps, motors, etc., the combined shock-absorbing bushing assembly can effectively reduce equipment vibration and noise, improve the stability and service life of the equipment, and protect the precision components of the equipment from vibration damage by absorbing and dispersing vibration energy. The existing shock-absorbing bushing assembly is usually a sleeve and a telescopic rod connected by a spring, which cushions the impact on the upper end and achieves the effect of shock absorption. However, the existing shock-absorbing bushing assembly is aimed at some special machines that require different shock absorption amplitudes. The existing shock-absorbing bushing assembly cannot adjust the shock absorption amplitude and there is no connection structure to combine with multiple groups of shock-absorbing bushing assemblies.

[0003] Therefore, it is necessary to provide a new combined shock-absorbing bushing assembly to solve the above technical problems. Utility Model Content

[0015] Compared with the related art, the combined shock-absorbing bushing assembly provided by the utility model has the following beneficial effects:

[0016] The utility model provides a combined shock-absorbing bushing assembly;

[0017] 1. The utility model can adjust the damping amplitude of the shock-absorbing bushing assembly by means of a limit bolt. When the damping amplitude of the shock-absorbing bushing assembly needs to be set for different purposes, a tool can be used to insert the upper end of the rotating limit bolt through the adjustment hole provided at the center of the upper end of the connector, thereby driving the limit ring which is sleeved and fixedly connected at the lower end of the limit bolt to move up and down inside the limit groove. When the upper end of the shock-absorbing bushing assembly is subjected to force, the extension and contraction distance of the deceleration spring is reduced, thereby reducing the damping amplitude of the shock-absorbing bushing assembly.

[0018] 2. The utility model can connect multiple groups of shock-absorbing bushing assemblies in parallel through the provided connecting plates. When multiple groups of shock-absorbing bushing assemblies need to be connected, the two sides of the connecting sleeves can be staggered and fixed by staggering the two sides of the connecting plates, and fixed by bolts through the opening at the center of the connecting plates, thereby realizing the parallel connection of multiple groups of shock-absorbing bushing assemblies.
