Induction anti-extrusion safety door

Abstract

The invention discloses an induction anti-extrusion safety door. The induction anti-extrusion safety door comprises a door frame and a door leaf hinged to the door frame. The door leaf is provided with a door lock handle. An electronic control telescopic structure connected with an electronic control unit is arranged on the upper border of the door frame. The telescopic end of the electronic control telescopic structure faces the door leaf. The induction anti-extrusion safety door further comprises human body induction sensors connected with the electronic control unit. The human body induction sensors are arranged at the positions, on the door lock handle side, of the door leaf, or the human body induction sensors are simultaneously arranged at the positions, on the door lock handle side,of the door leaf and the door frame, or the human body induction sensors are arranged at the positions, on the door leaf hinged side and the door lock handle side, of the door frame and the door leafcorrespondingly. By adopting the induction anti-extrusion safety door, through perception of the human body induction sensors to the human body and cooperation with the electronic control telescopicstructure, the problem that hands are extruded by the door can be effectively avoided, and normal use of the door is not affected.

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
