Abstract

The invention discloses an oil-gas integrated lifting seat rod which is composed of a central shaft, an inner shaft, a valve switch, a gas inlet rod, a gas rod plug and a movable shaft. Two oil cavities and two communicated gas cavities are formed in the seat rod, the oil cavities are closed or connected along with closing or opening of the valve switch, and lifting of the seat rod is controlled through flowing of liquid in the two oil cavities, so that the height of the seat rod can be located freely. Mutual adjustment of oil and gas is adopted to achieve the lifting function, the height can be freely adjusted according to needs of users, and the oil-gas integrated lifting seat rod is not prone to damage and convenient to adjust.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to an oil-gas integrated lifter seatpost. Background technique [0002] In daily life, when using a bicycle, due to factors such as the height of each person, it is usually necessary to adjust the height of the bicycle seat to meet the needs of people riding; most existing bicycles use springs or hydraulic structures to adjust The height of the bicycle seat, the traditional spring or hydraulic structure lifting seat post has defects such as difficult adjustment during use, short service life, easy to get stuck (cannot be reset), and cannot be repaired after being stuck. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-gas integrated drop seatpost that can be positioned arbitrarily and is conveniently adjusted. [0004] In order to solve the problems of the prior art, the technical solution adopted in the present invention ...
