[0002] Three-wing revolving doors are widely used in offices, hotels, shopping malls, airports and other places due to their simple, beautiful shape, economy and practicality. Anti-pinch protection of three-wing revolving doors has always been a design focus.

[0003] At present, the anti-pinch design for three-wing revolving doors usually installs anti-pinch rubber strips on the edges of the door wings of the revolving door, or installs sensors on the door wings of the revolving door. When the door wings of the revolving door sense that a person is pinched, they stop operating. This only takes into account people who have not entered the three-wing revolving door. If the three-wing revolving door stops suddenly, the people inside the three-wing revolving door will hit the three-wing revolving door and be frightened. Utility Model Content

[0006] As a further description of the above technical solution:

[0007] The telescopic rotating door wing mechanism includes a fixed frame, a movable frame, a telescope and a through-beam photoelectric sensor. The fixed frame is fixedly mounted on the support rod, the movable frame is slidably connected in the fixed frame, the telescope is arranged in the fixed frame, and the telescope connects the fixed frame and the movable frame. The through-beam photoelectric sensor is arranged on the edge of the movable frame, and the through-beam photoelectric sensor is electrically connected to the telescope, and the anti-pinch rubber strip is installed at the bottom of the fixed frame.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] 1. In the utility model, a basic three-wing revolving door is composed of a top fixing frame, a supporting profile, a driver, a supporting rod and three sets of telescopic revolving door wing mechanisms. The anti-pinch rubber strip is used to prevent pinching between the telescopic revolving door wing mechanism and the ground. When the telescopic revolving door wing mechanism senses that a body or object is pinched between the supporting profile, the telescopic revolving door wing mechanism contracts to leave a larger space between the telescopic revolving door wing mechanism and the supporting profile. During the process, there is no need for the entire three-wing revolving door to stop suddenly, thereby achieving a dynamic anti-pinch effect.

[0016] 2. In the utility model, when a body or an object is clamped between the movable frame and the supporting profile, the through-beam photoelectric sensor senses a signal and sends it to the telescope, and the telescope retracts to drive the movable frame to slide in the fixed frame, thereby leaving a large gap between the movable frame and the supporting profile, thereby playing an anti-pinch role.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a three-wing revolving door with an anti-pinch protection structure, comprising a top fixing frame 1, a plurality of supporting profiles 2, a supporting rod 3, a driver 4 and three sets of telescopic revolving door wing mechanisms 5, the outer contour of the top fixing frame 1 is circular, the upper ends of the plurality of supporting profiles 2 are fixedly connected to the top fixing frame 1, the upper ends of the supporting rods 3 are hinged to the top fixing frame 1, the driver 4 is installed on the top fixing frame 1, and the driver 4 is connected to and drives the supporting rods 3, the three sets of telescopic revolving door wing mechanisms 5 are arranged in a circular array and installed on the supporting rods 3, and the bottom of the telescopic revolving door wing mechanism 5 is provided with an anti-pinch rubber strip 6;

[0026] The telescopic revolving door wing mechanism 5 includes a fixed frame 51, a movable frame 52, a retractor 53 and a through-beam photoelectric sensor 54. The fixed frame 51 is fixedly mounted on the support rod 3, the movable frame 52 is slidably connected in the fixed frame 51, the retractor 53 is arranged in the fixed frame 51, and the retractor 53 connects the fixed frame 51 and the movable frame 52. The through-beam photoelectric sensor 54 is arranged on the edge of the movable frame 52, and the through-beam photoelectric sensor 54 is electrically connected to the retractor 53. The anti-pinch rubber strip 6 is installed at the bottom of the fixed frame 51. When a body or object is clamped between the movable frame 52 and the supporting profile 2, the through-beam photoelectric sensor 54 senses a signal and sends it to the retractor 53. The retractor 53 retracts to drive the movable frame 52 to slide in the fixed frame 51, thereby leaving a large gap between the movable frame 52 and the supporting profile 2, thereby playing an anti-pinch role.

[0027] Two first glass plates 7 are arranged on the fixed frame 51, and the two first glass plates 7 are located on opposite sides of the movable frame 52. A second glass plate 8 is arranged on the movable frame 52 to ensure the beauty and transparency of the decorative effect.

[0028] The fixed frame 51 is provided with a guide slot 9, the movable frame 52 is inserted into the guide slot 9, and the width of the movable frame 52 is the same as the width of the guide slot 9, so as to ensure the stable sliding of the movable frame 52;

[0029] An air-avoiding groove 10 is formed on the edge of the movable frame 52, and the through-beam photoelectric sensor 54 is arranged in the air-avoiding groove 10, which is convenient for the installation of the through-beam photoelectric sensor 54 and does not interfere with the normal operation of the three-wing revolving door.

[0030] Working principle: First, when the three-wing revolving door is actually used, two curved glass plates are installed on multiple supporting profiles 2, and the rotation of the driver 4 drives the support rod 3 to rotate, and the rotation of the support rod 3 drives the three sets of telescopic revolving door wing mechanisms 5 to rotate. The anti-pinch rubber strip 6 is used to prevent pinching between the telescopic revolving door wing mechanism 5 and the ground. Secondly, when a body or object is clamped between the movable frame 52 and the supporting profile 2, the through-beam photoelectric sensor 54 senses a signal and sends it to the telescope 53. The telescope 53 retracts and drives the movable frame 52 to slide in the fixed frame 51. At this time, the movable frame 52 slides along the guide groove 9. Finally, a large gap is left between the movable frame 52 and the supporting profile 2, which plays an anti-pinch role.
