Abstract

See full text

A height adjusting device for a bicycle seat post provides an up-down adjust unit. All the oil-flow control elements of the height adjusting device are arranged inside the up-down adjust unit. The oil flows between the valve port and the oil-block plate are blocked by both the oil-block plate and the valve port touching tightly in an up-down engaging manner. By the structure, what repairing the oil-flow control elements needs is to replace the up-down adjust unit when the oil-flow control elements are out of work. Therefore, it is convenient to repair and assemble. The valve port and the oil-block plate are arranged up and down so that they may touch each other closely in surfaces engaging. Thus, it provides good oil-blocking effects. Besides, the oil-block plate receives no shear stress occurring in the prior art generated from suddenly pressing down the seat. Therefore, it has a long service life.
