[0029] Embodiment 1

[0030] Please see attached Figure 1 -Attached Figure 8 As shown, a revolving door structure for preventing pinching includes a base plate 1, a pair of arc-shaped outer doors 2 distributed on the left and right are fixedly provided on the top surface of the base plate 1, a dome 3 is fixedly provided on the top of the arc-shaped outer door 2, a rotating shaft 4 is provided between the top surface of the base plate 1 and the middle of the bottom surface of the dome 3, the rotating shaft 4 is driven by a power device to rotate at a constant speed, and the upper and lower parts of the circumferential outer wall of the rotating shaft 4 are both rotatably sleeved with fixed sleeves 5, and three door panel fixing frames 6 uniformly distributed axially around the fixed sleeves 5 are fixedly connected to the circumferential outer walls of the upper and lower fixed sleeves 5.

[0031] An installation groove 13 is reserved on the outer surface of the door panel fixing frame 6, and a door panel 7 is fixed in the installation groove 13. A connecting plate 8 is fixed to the other end of the door panel 7. A telescopic fan blade plate 9 is fixed on the front side of the connecting plate 8. The telescopic fan blade plate 9 is composed of a pair of left and right retractable elastic plates and has good plasticity. A buffer plate 10 is fixedly connected to the front side of the telescopic fan blade plate 9. A slide groove 14 is reserved on the buffer plate 10. The slide groove 14 is provided with a pair of left and right. The brush plate 11 is slidably connected to the slide groove 14 on the same side. A number of evenly distributed bristles 12 are arranged on the brush plate 11. The bristles 12 are filamentous artificial fibers, and the outer ends of the bristles 12 are close to the inner wall of the curved outer door 2.

[0032] Through the above structure, the bristles 12 connected to the outer end of the door panel 7 can effectively allow hard objects to pass through the bristles 12, thereby preventing the fingers of pedestrians entering the revolving door from being pinched and injured by the inner wall of the curved outer door 2. In addition, when the telescopic fan plate 9 is subjected to pressure, it will shorten toward the inside of the door panel 7, thereby preventing objects or people who accidentally enter between the door panel 7 and the curved outer door 2 from being pinched between the door panel 7 and the curved outer door 2, thereby improving safety performance.

[0033] During the specific implementation of the utility model, when a pedestrian enters the revolving door, the power device drives the rotating shaft 4 to rotate at a constant speed, driving the door panel 7 to rotate slowly around the axis of the rotating shaft 4, and the pedestrian enters from the entrance to between the two door panels 7, and then walks down to the exit of the revolving door as the door panels 7 rotate, and finally enters and exits from the revolving door. When the pedestrian's hands or feet accidentally extend between the door panel 7 and the curved outer door 2, the pedestrian's hands and feet can smoothly enter and exit through the bristles 12 when the door panel 7 rotates, and will not be caught between the door panel 7 and the curved outer door 2, causing squeezing injuries. In addition, the telescopic blade plate 9 will shorten to the inner side of the door panel 7 under the action of pressure, so that objects or people who accidentally enter between the door panel 7 and the curved outer door 2 are prevented from being caught between the door panel 7 and the curved outer door 2, thereby improving safety performance.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
