本发明公开了止回装置及包含其的升降平台,升降平台包括:基座,设置有卡口;活动件,活动连接于基座上侧而能相对基座前后移动;卡件,活动连接于活动件而能相对活动件竖向移动,卡件能部分进入卡口并限制活动件往后移动,部分进入卡口的卡件往前移动时能脱离卡口;卡锁机构,设置于活动件,卡件往前移动而脱离卡口后,卡锁机构能将卡件锁止于活动件;解锁结构,设置于基座,被锁止于活动件的卡件随活动件往后移动而越过卡口后卡锁机构能通过与解锁结构配合而解除对卡件的锁止作用。上述的止回装置,能实现止回功能,并能通过活动件本身的运动解除锁止,从而无需运用主动动作的解锁动力源去实现止回功能的解锁,从而降低成本简化控制。

    The invention discloses a non-return device and a lifting platform comprising same. The lifting platform comprises a base, a movable part, a blocking part, a blocking part locking mechanism, and an unlocking structure, wherein a blocking hole is formed in the base; the movable part is movably connected to the upper side of the base, and can move front and rear relative to the base; the blocking part is movably connected to the movable part, and can vertically move relative to the movable part; the blocking part can partially enter the blocking hole and limits the movable part from moving backwards; the blocking part which partially enters the blocking hole can be separated from the blocking hole while moving forwards; the blocking part locking mechanism is arranged on the movable part, andcan lock the blocking part onto the movable part after the blocking part moves forwards and is separated from the blocking hole; and the unlocking structure is arranged on the base, wherein the blocking part locked to the movable part moves backwards along with the movable part to get across the blocking hole, and then the blocking part locking mechanism can be matched with the unlocking structure for eliminating the locking effect on the blocking part. The non-return device can realize a non-return function, and can eliminate locking through motion of the movable part, so that unlocking of the non-return function is realized without an unlocking power source in driving action, and therefore, the cost is reduced, and the control is simplified.
