The invention discloses a self-locking height adjuster which comprises a guide rail. Two sides of the guide rail are provided with racks. The adjuster also comprises a sliding block connected with the guide rail in a sliding mode, wherein two gears are arranged on the sliding block, the two gears are meshed with the racks respectively, and a gap is formed between the two gears; and a locking assembly arranged on the sliding block and comprises a locking block, wherein the locking block slides relative to the sliding block to be clamped into or slide out of a gap between the two gears so as to lock or unlock rotation of the gears. In the application, the locking force of the locking block on the gear can be increased along with the increase of the stress of the gear, so that the danger caused by locking failure due to excessive instant stress of the height adjuster when an automobile accident occurs can be avoided.

    本发明公开了一种自锁式高度调节器,包括:导轨,所述导轨的两侧分别设置一齿条;滑块,所述滑块与所述导轨可滑动连接,所述滑块上设置有两个齿轮,两个齿轮分别与一个齿条啮合,且两个齿轮之间具有间隙;锁止组件,设置在所述滑块上,其包括:锁止块,所述锁止块相对于所述滑块滑动以卡入或滑出两个齿轮之间的间隙以锁止或解锁所述齿轮的转动。本申请中,锁止块对齿轮的锁止力度可随齿轮受力的增大而增大,可避免汽车发生事故时高度调节器瞬间受力过大而锁止失效导致的危险。
