[0023] In this embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A commercial induction revolving door anti-pinch device includes a door seat 1, with a doorway 2 on one side of the door seat 1. A revolving door body 3 is rotatably connected inside the door seat 1. An opening fixing seat 6 is fixedly installed on one side of the doorway 2. A movable seat pivot 7 is rotatably connected to one side of the doorway 2. An opening movable seat 8 is fixedly installed on the outer side of the movable seat pivot 7. The opening movable seat 8 is adapted to the opening fixing seat 6. Specifically, the opening fixing seat 6 has a ratchet groove 61 inside, and a ratchet 82 is fixedly installed on one side of the opening movable seat 8. The ratchet 82 and the ratchet... The groove 61 engages with the door. In addition, the revolving door 3 is movably connected to the opening movable seat 8. Specifically, a blocking head 81 is fixedly installed on one side of the opening movable seat 8. The blocking head 81 is movably connected to the revolving door 3. Therefore, the rotation angle of the opening movable seat 8 can be adjusted by the movable seat shaft 7. Then, the opening movable seat 8 is fixed by the matching relationship between the blocking head 81 and the ratchet groove 61, thereby changing the distance between the blocking head 81 and the door frame 32, or by clamping the door frame 32 with the blocking head 81 to realize the locking operation of the revolving door 3, which facilitates the temporary isolation operation of personnel.

[0024] Other embodiments of this utility model: Please refer to Figure 5 The revolving door 3 includes glass 31 and a door frame 32. A rotating shaft 5 is rotatably connected inside the door seat 1. The door frame 32 is fixedly connected to the rotating shaft 5. Therefore, six sets of door frames 32 are arranged in a circular array outside the rotating shaft 5. The glass 31 is embedded inside the door frame 32. A groove is provided on one side of the door frame 32. The lowest point of the groove is 30cm from the ground, and the highest point of the groove is 180cm from the ground. Therefore, the groove length of 30-180cm is suitable for the use needs of children, adults, the elderly, and people of different heights. The groove can widen the gap with the opening movable seat 8, which can further protect people from being pinched. A spring telescopic column 33 is fixedly installed inside the groove. A movable plate 34 is fixedly connected to the side of the spring telescopic column 33 away from the door frame 32. The movable plate 34 is located inside the groove. The movable plate 34 can provide appropriate protection when a person's hand comes into contact with the opening movable seat 8 and is pinched.

[0025] Other embodiments of this utility model: Please refer to Figure 5 A handrail 4 is fixedly installed on one side of the glass 31. The outer side of the handrail 4 is provided with anti-slip texture, which allows people to hold it directly and avoids the problem of pinching their hands.

[0026] The working principle of this utility model is as follows: due to the setting of the groove, there is a certain width gap between the opening movable seat 8 and the person's hand, which can reduce the probability of the person's hand being squeezed by the moving rotating door body 3 and the opening movable seat 8. At the same time, the setting of the spring telescopic column 33 and the movable plate 34 can also provide a certain buffer protection when the hand is pinched, reducing injury.

[0027] Meanwhile, the rotation of the opening movable seat 8 can temporarily block the shield head 81 from the revolving door body 3, thereby guiding people in batches, strengthening management and further reducing the risk of injury when people pass through.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
