Induction crowding prevention safety door

Abstract

The invention discloses an induction crowding prevention safety door which comprises a door frame and a door sash. A door lock handle is arranged on the door sash, the door frame is provided with an electronic control telescopic structure which is connected with an electronic control unit and vertically arranged, and the telescopic end of the electronic control telescopic structure faces an upperframe body of the door frame. A locking guide rail which extends towards the hinged side of the door sash in an arc-shaped mode is arranged at the position, on the same side as the electronic controltelescopic structure, of he door frame, and the lower surface of the locking guide rail is higher than the top end of the door sash and is provided with a locking structure. The induction crowding prevention safety door further comprises human body induction sensors connected with the electronic control unit. The human body induction sensors are arranged at the position, on the door lock handle side, of the door sash, or the human body induction sensors are simultaneously arranged at the positions, on the door lock side, of the door sash and the door frame, or the positions, on the door sash hinged side and the door lock handle side, of the door frame and the door sash are both provided with the human body induction sensors. The problem the hands are squeezed by the door is solved throughthe induction to human bodies of the human body induction sensors and the cooperation of the electronic telescopic structure and the locking guide rail, and normal using of the door is not influenced.

Description

technical field [0001] The invention belongs to the technical field of building doors and windows, in particular to an induction anti-crowding safety door. Background technique [0002] At present, most of the doors (including hinged door leaves and door frames) are swing doors. When children open or close the door, due to limited control ability, there will be a danger of squeezing hands. Therefore, it is necessary to design a safety door. On the premise of not affecting the normal use of the door, it can achieve the effect of anti-crowding. [0003] Simultaneously, also there is following problem in existing door: [0004] 1. Children aged two or three are short in height and cannot reach the door lock handle when opening the door, so they cannot open the door by themselves; [0005] 2. When the child is alone in the room and the door is closed, if he needs to ask for help, due to the isolation of the door, the child's call is not easy to be heard by people outside, whic...

AI Technical Summary

Problems solved by technology

[0004] 1. Children aged two or three are short in height and cannot reach the door lock handle when opening the door, so they cannot open the door by themselves;

[0005] 2. When the child is alone in the room and the door is closed, if he needs to ask for help, due to the isolation of the door, the child's call is not easy to be heard by people outside, which will cause unnecessary accidents;

[0006] 3. In order to prevent the opened door leaf from being blown by the wind, there is a door stopper between the door leaf and the ground or wall. Due to the excessive magnetic force of the door stopper, it is difficult for children to close the door; moreover, since the door stopper is set at the bottom corner of the door leaf , when the door touch is closed or disengaged, the door leaf will be subject to a large shear force, and long-term use will cause the door leaf to deform and affect the service life of the door leaf
