The middle automatic swing door can achieve single-way, two-way passage and normally open operation modes. In an emergency, it can be used as a sliding door or fully opened to allow people to pass quickly.

[0003] Revolving door pinching incidents happen from time to time. In order to solve this problem, anti-pinch sensors are usually installed on the revolving door. When the distance between the person and the revolving door reaches a certain distance, the anti-pinch sensor sends a signal to the control system to move the revolving door toward the center. However, the existing traction mechanism is usually set at the top, and there is no traction mechanism at the bottom, which will cause the revolving door to be out of sync during the contraction process, causing the revolving door to tilt and even get stuck in severe cases.

The first pulley 6 is coaxially fixedly connected to a second pulley 112. A belt 113 is sleeved between the second pulley 112 and the third pulley 114.

[0028] When the upper traction mechanism is in action, the first motor 111 is started to drive the third pulley 114 to rotate, and the second pulley 112 is driven to rotate through the belt 113. The first pulley 6 rotates synchronously with the second pulley 112, thereby driving the conveyor belt 7 to move. The conveyor belt 7 drives the slide 8 to move in a straight line, and the slide column 10 at the end of the connecting rod 9 cooperates with the slide groove to pull the revolving door body 3 to move in a straight line, away from the outer arc door body 1, so that there is a certain gap between the revolving door body 3 and the outer arc door body 1 to avoid people being pinched.
