Abstract

The invention discloses a flapping type door leaf anti-pinch device. The flapping type door leaf anti-pinch device and method comprise two gate main bodies which are oppositely arranged and two flapping type door leaves which are connected with the gate main bodies and oppositely arranged, wherein a control device for controlling opening and closing of the flapping type door leaves is arranged inthe gate main bodies; at least one ultrasonic sensor is arranged on at least one flapping type door leaf and used for detecting whether the distance between a passing person and the flapping type doorleaf is smaller than a preset distance or not; and when the distance is smaller than the preset distance, the control device controls the door leaves to stop closing. By means of the mode, the mistaken clamping phenomenon caused by a detection blind area of an infrared sensor can be effectively avoided.

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...
