The top of the vertical shaft 3 passes through the top of the plate body 1 and is fixed with a handle 12. By rotating the handle 12 forward or reversely, the handle 12 can drive the vertical shaft 3 to rotate forward or reversely, and the vertical shaft 3 can drive the two first bevel gears 4 to rotate forward or reversely at the same time. Each first bevel gear 4 can drive the two second bevel gears 5 on the same axis to rotate in opposite directions, so that the two horizontal shafts 6 on the same axis rotate in opposite directions, so that the two first outer sleeve rods 7 on the same axis can move away from each other or move towards each other, and then the two support plates 8 can move away from each other or move towards each other, so that the protective device can be fixed at the elevator entrance.

[0019] On one side of the support plate 8, a second outer rod 11 is fixed at equal intervals between the two second outer rods 11, and an inner rod 10 is slidably installed inside the second outer rod 11. The end of the inner rod 10 is fixedly connected to the outer wall of the plate body 1, ensuring that when the support plate 8 moves, the support plate 8 can drive the second outer rod 11 to slide on the inner rod 10, and the design of the inner rod 10 and the second outer rod 11 can prevent people from passing through the protective device.

[0020] Working principle: When using the building safety protection device, firstly, by rotating the handle 12 forward or reversely, the handle 12 can drive the vertical shaft 3 to rotate forward or reversely, and the vertical shaft 3 can drive the two first bevel gears 4 to rotate forward or reversely at the same time, and each first bevel gear 4 can drive the two second bevel gears 5 on the same axis to rotate in opposite directions, so that the two horizontal shafts 6 on the same axis can rotate in opposite directions. Since the horizontal shaft 6 and the first outer rod 7 are threadedly connected, the two first outer rods 7 on the same axis can move away from each other or move towards each other, thereby making the two support plates 8 move away from each other or move towards each other, so that the protection device can be fixed at the elevator entrance;

[0021] When the support plate 8 moves, the support plate 8 can drive the second outer rod 11 to slide on the inner rod 10, and the design of the inner rod 10 and the second outer rod 11 can prevent people from passing through the protective device.
