Abstract

The present application discloses a slap-type fan door anti-pinch device. The slap-type fan door anti-pinch device and method include: two oppositely arranged gate bodies and two oppositely disposed flapper gates connected to the gate body. wherein, the main body of the gate is provided with a control device for controlling the opening and closing of the slap-type door; at least one of the slap-type doors is provided with at least one ultrasonic sensor, which is used to detect the relationship between the passer-by and the Whether the distance of the flapping door is less than the preset distance; and when the distance is less than the preset distance, the control device controls the door to stop closing. Through the above method, it is possible to effectively avoid the false clamping phenomenon caused by the detection blind area of ​​the infrared sensor.

Description

technical field [0001] This proposal mainly relates to the technical field of gates for pedestrian passages, especially the anti-pinch technology of flapping doors. Background technique [0002] Pedestrian passage gate is a kind of passage blocking device, which is widely used in the scene of managing the flow of people and regulating the entry and exit of pedestrians. Generally, two turnstiles form a pedestrian passage, and the doors of the turnstiles are automatically opened after the authorization of the passers-by, and the legal passers-by pass through the turnstile. The door forms of turnstiles mainly include three-stick door, scissors door, and flapping door. The three-stick type door relies on the passers-by to manually push the rod to pass through. After the gear stick is pushed away, the next gear stick moves to the horizontal position to form a barrier. The three-stick type door can effectively avoid multiple people passing at the same time, but its transmission s...
