ELASTICITY-ADJUSTABLE CORRUGATED CAVITY FLUID PRESSURE SPRING STRUCTURE

WIPO Patent Application WO/2014/075420

A1

Disclosed is an elasticity-adjustable corrugated cavity fluid pressure spring structure, the main structure thereof being a sealed cavity (6) composed of an elastic corrugated pipe (7) and an upper and a lower surface (1), one or more sets of channels (3) provided with valves (4) and an elastic structure (5) capable of accommodating excess fluid are connected to the outer side of the cavity (6), and the channels (3) are connected to the cavity (6) in a conducting manner; peak or trough portions of the corrugated pipe (7) can be embedded with rigid skeletons (2) so that the remaining portions with thinner walls are able to expand; and the cavity (6) can be provided with a pull rope therein, the pull rope being connected to the upper surface and the lower surface (1) of the cavity (6) respectively. By means of the valves (4) being adjusted in advance or during use, a fluid flows into the cavity (6) from outside via the channels (3) or flows out of the cavity (6), so that the internal pressure of the cavity (6) can be adjusted and controlled, and changes of axial elastic force can be realized.
