[0032] During installation, the left movable frame 101 and the right movable frame 102 can be driven to move closer or farther relative to each other through the adjusting mechanism 2 according to the specific size of the elevator shaft. After being adjusted to the appropriate position, they are locked through the locking mechanism 3 to adjust the size of the opening area of ​​the protective device. This is practical and convenient. At the same time, a left pressing mechanism 4 and a right pressing mechanism 5 are provided to press on the opposite side walls of the elevator shaft respectively. The fixation can be completed through the interaction force between the protective device and the side walls of the elevator shaft. There is no need to drill holes in the wall and then screw them in for fixation. This is practical and convenient.

[0033] Furthermore, the adjustment mechanism 2 includes an adjustment slot 21 provided at the lower end of the protective frame 100, a rotating screw 22 rotatably provided in the adjustment slot 21, and an adjustment component 23 provided in the middle of the adjustment slot 21 and transmission-connected to the rotating screw 22. The lower ends of the opposite sides of the left movable frame 101 and the right movable frame 102 are also respectively provided with adjustment blocks 24 threadedly sleeved on the rotating screw 22, wherein rotating the adjustment component 23 drives the rotating screw 22 to rotate, so as to allow the two adjustment blocks 24 to move synchronously closer or farther away along the rotating screw 22 toward the adjustment component 23.

[0034] Specifically, the adjustment assembly 23 includes a transmission box 231 fixedly arranged in the middle of the adjustment slot 21 , the rotating screw 22 passes through the transmission box 231 and is transmission-connected thereto, and an adjustment rotating rod 232 is rotatably provided on the transmission box 231 .

[0035] During adjustment, the adjusting rod 232 is rotated, and the rotating screw 22 is driven to rotate through the transmission structure in the transmission box 231, thereby driving the adjusting block 24 to move synchronously closer or farther away along the rotating screw 22 toward the adjusting component 23, and then driving the left movable frame 101 and the right movable frame 102 to move synchronously closer or farther away, thereby realizing the size adjustment of the opening area of ​​the protective device, which is practical and convenient.

[0036] In this embodiment, the screw transmission structure adopted by the adjustment mechanism 2 is a commonly used existing technology in this technical field and will not be described in detail here.

Moreover, the elastic force released by the right elastic connecting member 523 after being squeezed and deformed can further press the right top pressure plate 522 against the side wall of the elevator shaft, thereby maintaining the fixed stability of the device.

[0046] In this embodiment, a plurality of anti-slip grooves 6 are also provided on the outer end surface of the right top pressure plate 522 to increase the friction between the right top pressure plate 522 and the side wall of the elevator shaft, thereby further improving the fixing stability of the device.

[0047] To sum up, during installation, the embodiment of the present application can drive the left movable frame 101 and the right movable frame 102 to move closer or farther relative to each other according to the specific size of the elevator shaft through the adjustment mechanism 2.
