The width of the protection door 100 is greater than the side wall 201 of the elevator shaft opening 200. The protection door 100 can cover the elevator shaft opening 200. The protection door 100 can block and protect the elevator shaft opening 200. The movable hook 300 on the protection door 100 can be hung on the inner side wall 201 of the elevator shaft opening 200. The movable hook 300 can facilitate the disassembly and installation of the protection door 100, which can reduce the problem of residual expansion screws when installing the protection door 100. Multiple movable hooks 300 are arranged around the side of the protection door 100, which can better fix the protection door 100 on the elevator shaft opening 200. The bottom of the protection door 100 is also hinged with A support rod 400, one end of which is hinged at the bottom of the protective door 100, and the other end of which is tiltedly arranged on the side wall 201 of the elevator shaft opening 200 away from the shaft opening. There are two support rods 400, and the two support rods 400 are respectively arranged on both sides of the door of the elevator shaft opening 200, and then a protective net 500 is placed between the two support rods 400. The protective net 500 can be unfolded and arranged in the elevator shaft, so that the protective net 500 can take on the problem of falling. The hinged connection between the protective door 100 and the support rod 400 can facilitate the installation of the protective net 500 and the protective door 100. The protective door 100 is restricted to the elevator shaft opening 200 by the movable hook 300, which can prevent the support rod 400 from escaping from the elevator shaft, and the support rod 400 can stably support the protective net 500.

In case of a falling problem, the protective cross bar 103 is connected to one end of the protective vertical bar 102 and continues to extend to both sides to form a blocking rod 104. When the protective door 100 is in use, the protective vertical bar 102 is set on the inner side of the elevator shaft opening 200 for connecting the movable hook 300, which can facilitate the movable hook 300 to be hooked inside the elevator shaft opening 200. The blocking rod 104 extends on both sides and can be clamped on the outside of the elevator shaft opening 200, so that the protective door 100 can be covered at the elevator shaft opening 200.

[0037] Optionally, the ends of the two support rods 400 away from the protective door 100 are respectively connected with stabilizing rods, and both ends of the stabilizing rods are fixedly connected to the support rods 400. In this way, by connecting the stabilizing rod between the two support rods 400, the distance between the two support rods 400 can be stabilized by the stabilizing rod, so that the problem of objects falling on the protective net 500 causing the two support rods 400 to be close to each other can be prevented.
