Multi-stage spring shock absorber
The invention discloses a multi-stage spring shock absorber which comprises an outer sleeve, a first spring and a second spring. The first-stage vibration reduction unit comprises a sleeve, a top plate, a bottom plate and an outer spring, the sleeve is located in the outer sleeve and downwards protrudes out of the outer sleeve, the bottom plate is connected to the bottom end of the sleeve, the outer spring is located in the sleeve, the bottom end of the outer spring is located on the top plate, the top plate is jacked to the position above the sleeve through the top end of the outer spring, and a vibration reduction interval is formed between the top plate and the top end of the sleeve; the second-stage vibration reduction unit comprises an inner spring, a pressing plate, a top column and a limiting ring, the inner spring and the pressing plate are both located in the outer spring, the bottom end of the inner spring is located on the top plate, the pressing plate is located at the top end of the inner spring, the top column is connected to the pressing plate and penetrates out of the top plate upwards, and the limiting ring is arranged on the top column in a sleeving mode and located in the vibration reduction interval; according to the shock absorber, multiple springs are nested and matched in use, so that the shock absorber shows multiple self-adaptive rigidities, multi-stage shock absorption is achieved, and the structural safety under the vibration effect is effectively protected.
本发明公开了多级弹簧减振器，包括：外套管；一级减振单元，其包括套筒、顶板、底板与外弹簧，套筒位于外套管内并向下凸出于外套管，底板连接于套筒的底端，外弹簧位于套筒内，外弹簧的底端位于顶板上，外弹簧的顶端将顶板顶升至套筒的上方，顶板与套筒的顶端之间形成减振区间；二级减振单元，其包括内弹簧、压板、顶柱与限位环，内弹簧与压板均位于外弹簧内，内弹簧的底端位于顶板上，压板位于内弹簧的顶端，顶柱连接于压板上并向上穿出顶板，限位环套设于顶柱上并位于减振区间内，本发明通过内部多种弹簧嵌套搭配使用，使减振器表现为多种自适应刚度，实现多级减振，有效保护振动作用下的结构安全。
