Impact-type door openings such as trolleys allow people or goods to pass through faster and improve work efficiency; this device uses the cooperation of V-shaped grooves and rollers to make the door leaf rise to obtain gravitational potential energy when the door leaf rotates. When the door leaf loses the effect of external force, the potential energy Convert into kinetic energy, making the door leaf It automatically returns to the closed state, so that when the door leaf is statically closed, it is not easily blown open by wind and other airflow. This device cooperates with the cross-shaped concave block through the second roller, so that when the door leaf rotates 90 degrees, it is in a locked state and will not automatically recover. Movement, and thus easy to use.
