The invention discloses a locking mechanism and a seat height adjuster, the locking mechanism comprises a rotating part, a fixing assembly and a locking part, the fixing assembly sleeves the rotating part, a wedge-shaped cavity is formed between the fixing assembly and the rotating part, and the locking part is arranged in the wedge-shaped cavity and can rotate along the circumferential direction along with the rotating part to a locking position or an unlocking position; the fixing assembly comprises a shell and a sleeve body connected with the shell, and the sleeve body comprises a plurality of layers of stacked bodies which are sequentially stacked in the axial direction. According to the locking mechanism, in the locking process and the unlocking process, the deformation degree of the fixing assembly is smaller, and therefore the stroke is small and the neutral gear feeling is weak when the rotating piece is operated to rotate. And moreover, the existing parts and interfaces of the existing seat heightening device can be maximized, so that the seat heightening device has the advantages of low improvement cost and good universality.

    本申请公开了一种锁止机构及座椅调高器,所述锁止机构包括:转动件,固定组件和锁止件,所述固定组件套在所述转动件外且两者之间形成楔形腔、所述锁止件布置在所述楔形腔内并能随所述转动件沿周向旋转运动到锁止位或解锁位;所述固定组件包括外壳和与所述外壳连在一起的套体,套体包括沿轴向依次层叠的多层层叠体。该锁止机构,在锁止过程和解锁过程中,固定组件的变形程度更小,所以操作转动件旋转时空行程小,空挡感弱。而且,能最大限度的既有的座椅调高器的既有零件和接口,因而还具有改造成本低、通用性好的优势。
