Title:
SELF-LOCKING SYNCHRONIZED MULTI-STAGE GAS SPRING
Document Type and Number:
WIPO Patent Application WO/2020/034551
Kind Code:
A1
Abstract:
A self-locking synchronized multi-stage gas spring. Piston rods of multiple stages are designed to be combined into an integrated structure having multiple sections operating synchronously, wherein a first-stage piston rod (1) serves as a cylinder for a second-stage piston rod (2), the second-stage piston rod (2) serves as a cylinder for a third-stage piston rod, and so on. When compressed, the piston rods at each stage can all be compressed and contained in a first-stage cylinder (9), such that the length of the whole cylinder is shortened and the stroke length is increased, thereby remedying the technical defect of the present product in the art in which a stroke is shorter than the length of the cylinder.
