Application method of automatic door capable of preventing clamping
The invention provides an application method of an automatic door capable of preventing clamping. The automatic door capable of preventing clamping comprises a door frame, a movable door and a clamping preventing device, wherein the clamping preventing device comprises a shell, a swinging device, a lever device and a door brake device; the clamping preventing device is mounted at the bottom end of the movable door; the swinging device comprises a pendulum bob, a driving piece, and a first guide sleeve; wherein the door brake device comprises a brake piece, a first spring and a second guide sleeve; the lever device comprises a first lever, a first supporting piece, a second lever and a second supporting piece; the swinging device is connected with the lever device; the lever device is connected with the door brake device; when the automatic door clamping preventing is used, the rapid swinging inertia of the movable door drives the pendulum bob to swing, and the pendulum bob is used for driving the first lever and the second lever to swing; the second lever swings to drive the brake piece to overcome elastic force of the first spring so as to move downwards, and furthermore, the brake piece is descended to be in contact and friction with the ground; and the movable door is effectively prevented from being rapidly swung, and children are prevented from being injured by rapidly swinging the movable door.
