DROPPER SEATPOST FACILITATING OF ADJUSTING FLUID PRESSURE

Abstract: a dropper seatpost includes an outer tube and an inner tube disposed in the outer tube and having a first oil chamber and a second oil chamber connected to the first oil chamber. a fluid chamber is provided between the top and bottom ends of the inner tube. a pressure adjustment member is disposed in the first oil chamber to push the oil from the first oil chamber to the second oil chamber. a floating piston is disposed between the second oil chamber and the fluid chamber and pushed by the oil stored in the second oil chamber to compress the high-pressure fluid stored in the fluid chamber. thus, the present invention allows a user to conveniently adjust pressure of the high-pressure fluid. the arrangement of the first and second oil chambers does not significantly compromise the structural integrity of the inner tube, ensuring that it provides effective support.
