Abstract

The invention relates to the technical field of door blocking devices, and particularly relates to a blocking safety device for an anti-collision door. The blocking safety device comprises a wall, a door frame mounted on the wall and a door plate rotatably connected to the door frame, wherein the inner side wall of the door frame is fixedly connected with a fixing piece, a limiting piece is inserted into the fixing piece, one side of the limiting piece makes contact with the side wall of the door plate and the side wall of the door frame, and a supporting piece used for supporting the limitingpiece is fixedly arranged on the wall. According to the blocking safety device, the blocking safety device is fixed to the inner side wall of the door frame through screws, falling caused by violentdoor pushing is avoided, and stability is good; the blocking safety device is not prone to being touched, the situation that the blocking safety device is opened from the outside of the door is avoided, and safety is high; and the force bearing direction of the blocking safety device is perpendicular to the screw fixing direction, stability is better, and the blocking safety device is not prone tobeing damaged.

Description

technical field [0001] The invention relates to the technical field of door blocking devices, and more specifically relates to a blocking safety device for an anti-collision door. Background technique [0002] The blocking safety device for the anti-collision door is a kind of door stopper, which is a device that prevents the door from being opened from the outside. It is usually installed indoors to prevent criminals from prying open the door lock and opening the door from the outside. [0003] At present, the safety measures in the closed back door mainly include: anti-lock, latch, chain bolt, etc., all of which have the following disadvantages: [0004] 1. The latch is installed on the surface of the door and the door frame by screws. If the door is pushed violently, the screws are difficult to be firm and easy to fall off; [0005] 2. The chain bolt is easy to touch and can be cut and opened directly; [0006] 3. Traditional methods such as anti-locking the door are co...
