The lifting sliding door system applies the principle of leverage. After gently rotating the handle, it controls the lifting and lowering of the door leaf to complete the opening and fixing of the door leaf. Through the driver connected with it, the pulley falls on the track of the lower frame and drives the door leaf to lift up. The pulley is separated from the track of the lower frame and the door leaf descends. The door leaf is tightly pressed against the door frame by gravity, and the door leaf is in a closed state at this time.
