[0014] 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 in 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.

[0015] See also Figures 1 to 3 The embodiment of the utility model provides a subway safety door protection device, including a frame part 1 and a plurality of groups of protection parts 2 embedded in the inner side of the frame part 1, each group of protection parts 2 includes a first arc plate 21 and a second arc plate 22, the first arc plate 21 and the second arc plate 22 are shaped like an arch, and the advantage of the arch structure is that when subjected to pressure, the pressure can be evenly distributed to each part, and the external extrusion can be resisted, especially when the subway entrance is crowded, it can play a good protective role, in addition, because the concave side of the first arc plate 21 and the concave side of the second arc plate 22 are arranged opposite to each other, they can play a protective and anti-extrusion role from both the inside and the outside.

[0016] The first curved plate 21 and the second curved plate 22 are fixedly connected to the opposite surface with a first spring 23. When the first curved plate 21 or the second curved plate 22 is squeezed from the outside, on the one hand, the elastic deformation of the first spring 23 can be used to relieve the force. The two ends of the first curved plate 21 are fixedly connected to the first push plate 24, and the two ends of the second curved plate 22 are fixedly connected to the second push plate 25 that exceeds the first push plate 24. The opposite surface of the first push plate 24 and the second push plate 25 is fixedly connected to the second spring 26. A third spring 27 is provided between the second push plate 25 and the inner side wall of the frame part 1. On the other hand, when the first curved plate 21 or the second curved plate 22 is squeezed from the outside, on the other hand, the elastic deformation of the first spring 23 can be used to relieve the force. When externally squeezed, the plate body will be deformed, not only the gap between the first curved plate 21 and the second curved plate 22 will be smaller, but also the first curved plate 21 and the second curved plate 22 will tend to extend to both sides. When the first curved plate 21 is subjected to external squeezing, the first push plate 24 squeezes the second spring 26, the second spring 26 squeezes the second push plate 25, and the second push plate 25 squeezes the third spring 27. The force can be relieved by the elastic deformation of the second spring 26 or the third spring 27 or both. When the second curved plate 22 is subjected to external squeezing, the second push plate 25 squeezes the third spring 27, and the force is relieved by the elastic deformation of the third spring 27.

[0017] The frame part 1 includes two side plates 11 and end plates 12 fixedly connected to the upper and lower parts of the two side plates 11, and the fixed connection method can be screw connection or welding. A first groove 28 is provided inside the side plate 11, and the first push plate 24 and the second push plate 25 are accommodated in the first groove 28, so that the movement of the first push plate 24 and the second push plate 25 can be limited in the first groove 28. Figure 1 As shown in the figure, due to the obstruction of the first push plate 24, the second push plate 25 is difficult to be laterally separated from the first groove 28, and the first push plate 24 is also difficult to be completely laterally separated from the first groove 28 due to the obstruction of the arched portion of the second arc plate 22.

[0018] Furthermore, one end of the third spring 27 facing away from the second push plate 25 abuts against the first groove 28 .

[0019] It is understood that the above description is only exemplary and the embodiments of the present application are not limited thereto. Although the embodiments of the present utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the attached claims and their equivalents.
