[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a two-wing rotating retracting anti-pinch door leaf, comprising a side wing door 1, an upper guide rail 9 and a lower guide rail 8 fixed to the front side of the side wing door 1, a revolving door 2 is arranged on the front side of the side wing door 1, and the revolving door 2 is slidably arranged on the surface of the upper guide rail 9 and the lower guide rail 8. The upper guide rail 9 and the lower guide rail 8 linearly guide the revolving door 2, and the revolving door 2 can linearly move along the surface of the upper guide rail 9 and the lower guide rail 8. An anti-pinch sensor 14 is fixedly installed at the front edge of the side wing door 1;

[0024] A driving assembly is fixedly installed on the front side of the wing door 1 , and a traction piece 7 is connected to the driving assembly. The traction piece 7 is fixedly connected to the top of the revolving door 2 .

[0025] When the anti-pinch sensor 14 detects that a person is approaching, the driving component pulls the revolving door 2 to move away from the person, thereby realizing the retracting function and avoiding pinching the person. Moreover, under the action of the synchronous traction component, the upper and lower ends of the revolving door 2 can move synchronously, that is, move in a straight line in a straight and stable state, thereby solving the problem of the revolving door 2 being out of sync or even stuck in the prior art.

[0026] Specifically, the driving assembly includes a motor 3 fixed to the front side wall of the wing door 1, a first pulley 4 fixed to the output end of the motor 3, a second pulley 6 is rotatably inserted into the front side wall of the wing door 1, a belt 5 is tightly sleeved between the second pulley 6 and the first pulley 4, and the belt 5 is fixedly connected to the traction plate 7.

[0027] When the anti-pinch sensor 14 detects that a person is approaching, the control system will immediately stop the rotation of the revolving door 2, which is the prior art; then the anti-pinch sensor 14 sends a signal to the central controller, which starts the motor 3, and the motor 3 drives the first pulley 4 to rotate, and with the cooperation of the second pulley 6, the belt 5 moves, and the belt 5 pulls the revolving door 2 to move in a straight line through the traction plate 7, so that the revolving door 2 is away from pedestrians, thereby achieving the anti-pinch purpose.

[0028] In addition, the first pulley 4 and the second pulley 6 are of the same size, which facilitates ensuring that the belt 5 is in a horizontal state, realizes horizontal traction of the revolving door 2, and ensures the stability and effect of the traction.

[0029] The belt 5 is a synchronous toothed belt, which transmits power by meshing teeth with each other. It has the characteristics of high transmission accuracy and low noise, and is suitable for occasions requiring precise transmission.

[0030] In the present scheme, a synchronous traction assembly is arranged on the front side of the wing door 1, and the synchronous traction assembly includes two sets of upper and lower guide wheel mechanisms and a wire rope 13. The guide wheel mechanism includes a first guide wheel 10, a second guide wheel 11 and a third guide wheel 12, which are all rotatably inserted in the front side wall of the wing door 1. In addition, the first guide wheel 10, the second guide wheel 11 and the third guide wheel 12 have the same specifications. The wire rope 13 is wound and arranged between the first guide wheel 10, the second guide wheel 11 and the third guide wheel 12. The wire rope 13 is fixedly connected to the revolving door 2. Specifically, the wire rope 13 is in a concave shape inclined at 90° as a whole, and the wire rope 13 has four lines in the vertical direction. The second line and the fourth line of the wire rope 13 are fixed to the revolving door 2, so that the synchronous horizontal linear traction of the revolving door 2 can be achieved.

[0031] When the belt 5 pulls the revolving door 2, the revolving door 2 also pulls the steel wire rope 13 to move on the first guide wheel 10, the second guide wheel 11, and the third guide wheel 12; the steel wire rope 13 synchronously pulls the upper and lower sides of the revolving door 2 in a horizontal straight line, thereby solving the problem of the revolving door 2 being out of sync, tilting, or even getting stuck, and ultimately preventing the revolving door 2 from contacting people, thereby realizing the anti-pinch function.
