The invention discloses a stepless height adjuster which comprises a guide rail and a sliding assembly. The sliding assembly is arranged on the guide rail in a sliding mode and comprises a locking mechanism, a sliding plate assembly and a pressing piece capable of resetting automatically. The pressing piece is arranged on the sliding plate assembly, and the sliding plate assembly is limited by thetwo side walls in the guide rail so that the sliding plate assembly can only slide in the length direction of the guide rail. The locking mechanism comprises at least one locking block in movable contact with the base, and the pressing piece is used for driving the locking block to be away from the base so as to unlock the sliding assembly. According to the stepless height adjuster, the height can be adjusted steplessly, locking of a sliding assembly is achieved through static friction between a locking block and a guide rail, when the height is adjusted downwards, position locking of a locking mechanism and the sliding assembly can be relieved by pressing the pressing piece, and when the height is adjusted upwards, unlocking operation is not needed; and the sliding assembly can be directly pushed to realize upward height adjustment.
本发明公开一种无级高度调节器,其包括导轨和滑动组件;滑动组件可滑动的设置于所述导轨上,所述滑动组件包括锁止机构、滑板组件和可自动复位的按压件;所述按压件设置于所述滑板组件上,所述导轨中两侧壁限位所述滑板组件使其仅可沿所述导轨长度方向滑动;所述锁止机构包括与所述基座活动接触的至少一个锁止块,所述按压件用于驱动所述锁止块远离所述基座以解锁所述滑动组件。本发明公开了一种无级高度调节器,可无级调节高度,通过锁止块与导轨的静摩擦实现对滑动组件的锁止,在往下调节高度时,通过按动按压件,便可解除锁止机构与滑动组件的位置锁定,在往上调节高度时,无需进行解锁操作,可直接推动滑动组件实现往上调高。
