Self-control door capable of preventing clamping
The invention provides a self-control door capable of preventing clamping. The self-control door comprises a door frame, a movable door and an clamping preventing device, wherein the clamping preventing device comprises a shell, a left pendulum bob, a right pendulum bob, a driving piece, a first guide sleeve, a first supporting piece, a first lever, a second supporting piece, a second lever, a brake piece, a second guide sleeve and a first spring; the driving piece is provided with a left driving surface and a second driving surface; the first lever is connected with the first supporting piece and the second lever is hinged with the second supporting piece; the brake piece is in movable match connection with the second guide sleeve; when the self-control clamping preventing door is used, the movable door is blown by air to be rapidly closed and opened, and the left pendulum bob and the right pendulum bob are used for driving the driving piece, the first lever, the second lever and the brake piece to move, so that the brake piece descends to be in contact and friction with the ground; and brake force of the brake piece is increased by using the first lever and the second lever, so that the movable door is effectively prevented from being rapidly closed and opened, and children are prevented from being clamped or injured by the movable door.
