Detailed Description of the Invention

[0020] The following further elaborates on the present application in Figures 1 - 3 with reference to the attached drawings.

[0021] The embodiment of the present application discloses a stair passage protection device. Refer to Figures 1 - 3, A staircase passage protection device, including a staircase passage 1, on which a staircase guardrail 2 is installed. The staircase guardrail 2 includes a handrail 201 installed on the staircase passage 1. The handrail 201 is arranged along the direction of the staircase passage 1. A number of columns 202 are installed between the handrail 201 and the staircase passage 1. A mounting component 3 is also installed on the side of the staircase passage 1. A protection net 4 is installed between the mounting component 3 and the column 202. The mounting component 3 includes an inclined plate 301 installed on the side of the staircase passage 1. A number of clamping members 302 are installed on the inclined plate 301, and the clamping members 302 are detachably connected to the column 202. The protection net 4 is fixed on the side of the staircase passage 1 through the mounting component 3, forming a closed protection for the side of the staircase guardrail 2, which can effectively prevent objects from falling on the staircase passage 1 and then rolling down to form high-altitude falling objects.

[0022] Refer to Figure 2 , The lower end of the column 202 is installed with a mounting plate 203 through bolts. The mounting plate 203 is connected to the staircase passage 1 through expansion bolts. An inclined rod 204 is installed between two adjacent columns 202.

[0023] Refer to Figure 1 , The column 202 includes two support rods 2021 installed on the mounting plate 203. A certain gap is reserved between the two support rods 2021. A hook 2022 is installed at the upper end of the support rod 2021 on the staircase passage 1. The protection net 4 is suspended through the hook 2022 to form the fixation of the upper end of the protection net 4.

[0024] Refer to Figure 1 , The clamping member 302 includes two L-shaped rods 3021 fixedly installed on the inclined plate 301. A connecting plate 3022 is installed at the ends of the two L-shaped rods 3021. The column 202 is located inside the corresponding two L-shaped rods 3021. A locking bolt 303 is slidably installed between the two support rods 2021. The end of the locking bolt 303 passes through the connecting plate 3022 in a threaded manner.
