Abstract

The invention provides a double-wing safety rotating door which comprises a movable leaf, a fixed leaf, a driving system and a control device. The driving system comprises a rotating driving device and an arc door wing reverse driving device; and both the rotating driving device and the arc door wing reverse driving device are connected with the control device. The rotating door can be automatically retarded or stopped in a rotation danger collision region; inertial impaction to the rotating door is reduced; and human bodies can be effectively protected and are avoided being jammed or collided by the automatic door.

Description

technical field [0001] The invention relates to a revolving door, in particular to a two-wing safety revolving door. Background technique [0002] The structure of the existing revolving automatic door is as follows: figure 1 As shown, its structure is composed of a fixed fan 5' and a moving fan (composed of an exhibition box 3' and an arc door wing 2') that rotates around the rotation center 1' inside the fixed fan. There are door columns 6 at both ends of the fixed fan 5'. '; There are symmetrically arranged circular arc door wings 2' on the moving fan, and arc door wing columns 4' are arranged at both ends of the arc door wing 2'. [0003] Such as figure 1 As shown, when the arc door wing 2' rotates to a straight line distance of about 0.5-0.7 meters from the door column 6', if someone enters and exits the revolving door at this time, they will be bruised or pinched, causing the door body to hurt pedestrians. Therefore, this area is called the danger area at this time....
