AI Technical Summary
The blades of the air valve lack the limit self-locking function, which leads to the blades being easily affected when the air inlet or outlet volume is too large, or when it is accidentally bumped or affected by external wind force, resulting in unstable use of the air valve.
A air valve structure is designed, by setting air inlet and outlet inside the air valve and slidingly connecting the bearing plate on the inner wall of the air inlet and outlet, the bearing plate is rotatably connected with the rotating shaft and the blade. At the same time, the servo motor drives the linkage shaft and the bearing plate to slide and lift the linkage shaft and the side wall of the air valve through threaded connection to achieve thread self-locking.
By driving the sliding lifting of the rotating shaft of the blade and the bearing plate, the stable opening and closing of the blade is achieved, avoiding the influence of external forces and wind, and improving the stability of the use of the air valve.
