Device capable of automatically preventing clamping by door
The invention discloses a device capable of automatically preventing clamping by a door. The device comprises a housing, a swing device, a swing brake and a supporting spring, wherein the swing device comprises a hinge, a swing spring, a pendulum bob and a swing frame; a shaft hole is formed in the pendulum bob; a fixed shaft is arranged on the swing frame; the fixed shaft of the swing frame is connected with the shaft hole of the pendulum bob in a movable fit manner; the housing is connected with the hinge; the hinge is fixedly connected with the swing spring; the swing spring is fixedly connected with the swing frame; the swing brake is connected with the housing in the 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 is opposite to the pendulum bob. When the device is used, inertia force of the pendulum bob is used for overcoming anti-swing elastic force of the swing spring, so that the pendulum bob is driven to roll the upper end surface of the swing brake, 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 friction force, so that children can be effectively prevented from being clamped by the movable door.
