The pneumatic control handle comprises a guide part, a valve body, an ascending valve, a descending valve and a movable part, the guide part is fixedly clamped in the valve body, a first containing groove and a second containing groove are formed in the valve body, and an air source opening, an ascending air outlet and a descending air outlet are formed in the valve body; the air source opening is communicated with the ascending air outlet and the descending air outlet through the first containing groove and the second containing groove respectively, the ascending valve is arranged in the first containing groove, the descending valve is arranged in the second containing groove, the ascending valve and the descending valve each comprise at least one movable part, and the movable parts are arranged on the guide part. The ascending valve and the descending valve are driven to work through the movable part; by arranging the ascending valve, the descending valve and the movable part, the control method of an air path in the valve body is changed, during use, the ascending valve and the descending valve work, simultaneous air inflow of the two air inlet ends of the pneumatic lifting equipment is avoided, and normal use of the pneumatic lifting equipment is guaranteed.
本发明提出了一种气动控制手柄,包括导向件、阀体、上升阀、下降阀和活动件,所述导向件固定卡设在阀体内,阀体内设有第一容纳槽和第二容纳槽,所述阀体上设有气源口、上升出气口和下降出气口,气源口分别通过第一容纳槽和第二容纳槽与上升出气口和下降出气口相连通,所述上升阀设置在第一容纳槽内,下降阀设置在第二容纳槽内,上升阀和下降阀均包括至少一个活动部,所述活动件设置在导向件上,并通过活动部驱动上升阀和下降阀工作;通过设置上升阀、下降阀和活动件,改变了阀体内气路的控制方法,在使用时,上升阀和下降阀工作,避免了气动升降设备的两个进气端同时进气,保证了气动升降设备的正常使用。
