Using method for device capable of automatically preventing clamping by door
The invention discloses a using method for a device capable of automatically preventing clamping by a door. The device comprises a housing, a pendulum bob, a swing arm, a swing brake and a supporting spring, wherein the pendulum bob is hinged with the swing arm; the swing arm is connected with the housing; the swing brake is connected with the housing in a movable fit manner; the swing brake is positioned below the pendulum bob; the swing brake is positioned on a swing track position of the pendulum bob; a baffle plate is arranged on the swing brake; the baffle plate is opposite to the pendulum bob; the swing brake is supported on the supporting spring; the supporting spring is mounted on the bottom of the housing; the upper end surface of the swing brake is an inclined surface, and the inclined surface of the upper end surface is opposite to the pendulum bob; a ball joint is arranged on the swing arm, one end of the swing arm is connected with the ball joint, the ball joint is connected with the housing, a roller shaft is arranged at the other end of the swing arm, a shaft hole is formed in the pendulum bob, and the roller shaft of the swing arm is connected with the shaft hole of the pendulum bob in the movable fit manner. When the device is used, the pendulum bob is driven by inertia force of the pendulum bob to hydraulically press the upper end surface of the swing brake, and the swing brake is driven to descend to be in contact with the floor, and the movable door is prevented from being quickly closed through the friction force, so that children can be effectively prevented from being clamped by the movable door.
