The invention relates to the technical field of aero equipment, in particular to a self-locking aero seat capable of adjusting height steplessly. The self-locking aero seat capable of adjusting the height steplessly comprises column-shaped seat legs which are fixedly installed on a seat back of a seat pan through fixing seats in an opposite mode, an upper support frame and a lower support frame are fixedly installed between the seat legs, a sliding block is fixedly installed on the seat back, a threaded hole formed in the sliding block is connected with a threaded shaft in a matched mode, the threaded shaft is installed on the upper support frame and the lower support frame through a conical roller bearing, the threaded shaft penetrates through one end of the upper support frame and is fixedly connected with a worm gear which is connected with a worm arranged on supporting seats in a matched mode, the end of the worm is provided with a rotating wheel with a handle, a frictional angle of worm-gear transmission is larger than a lead angle, and a screw transmission frictional angle of the threaded shaft and the threaded hole is larger than the lead angle. According to the self-locking aero seat capable of adjusting the height steplessly, a braking system is not necessary due to the double self-locking property, defects that for a traditional height adjusting control device, the operation is complex, and misoperation is prone to occurring are overcome, the operation is simple, and the reliability is good.
