The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut.

[0005] According to the above technical solution, when a damaged protective net assembly needs to be dismantled, the first step is to loosen the screws on the fixed cover plate so that the threaded section of the screw is separated from the fixed frame. The second step is to separate the fixed cover plate from the fixed frame. The third step is to pull the two fixed brackets on the protective net assembly so that the connecting column moves out of the connecting opening, so that the limit block is separated from the inner groove wall of the fixed groove. When a new protective net assembly needs to be installed, the first step is to move the two fixed brackets on the protective net assembly to the corresponding position so that the connecting column passes through the connecting opening and the limit block is pressed against the inner groove wall of the fixed groove. The second step is to move the fixed cover plate to the side of the fixed frame close to the slope so that the notch of the fixed groove is blocked by the fixed cover plate. The third step is to use screws to press the fixed cover plate and the fixed frame together.

[0006] In summary, the passive slope protection net arranged as above detachably connects the protection net assembly to the fixed columns, making the disassembly, assembly and replacement of the protection net assembly more convenient.

[0007] Preferably, an external thread is provided on the outer side of the connecting column, a threaded hole is provided through the center of the limiting block, and the limiting block is threadedly connected to the connecting column via the threaded hole.

[0008] With this technical solution, when the limit stop is rotated forward, it abuts against the inner wall of the fixed groove, thereby improving the connection stability between the protective net assembly and the fixed column. When the limit stop is rotated backward, the distance between the two opposing limit stops can be increased, making it easier to disassemble and assemble the protective net assembly.

[0009] Preferably, an elastic gasket is sleeved on the outer side of the connecting column, and the limit block presses and fixes the elastic gasket on the inner groove wall of the fixing groove.

[0010] Through the above technical solution, the elastic gasket can exert elastic force on the limit block after being compressed, so that the teeth of the threaded hole and the teeth of the external thread are tightly pressed against each other, thereby preventing loosening.

[0011] Preferably, a fixing retaining ring is sleeved on the outer side of the connecting column, and the fixing bracket presses and fixes the fixing retaining ring to the outer side wall of the fixing frame.

[0012] Through the above technical solution, the fixed retaining ring can cover the connecting column to protect the connecting column. Furthermore, the two ends of the fixed retaining ring respectively press against the fixed bracket and the fixed column, which can improve the connection stability between the protective net assembly and the fixed column.

[0013] Preferably, a mounting opening is provided at the bottom of the fixing retaining ring, the width of the mounting opening is smaller than the diameter of the connecting column, and the fixing retaining ring is clamped onto the outer side of the connecting column via the mounting opening.

[0014] With the above technical solution, a mounting opening is provided at the bottom of the fixed retaining ring, making the assembly and disassembly of the fixed retaining ring more convenient.

[0015] Preferably, an elastic pressing block is provided at a position of the fixed cover plate opposite to the connecting opening, and the elastic pressing block presses the connecting column against the inner side wall of the connecting opening.

[0016] Through the above technical solution, the elastic pressure block presses the connecting column against the inner wall of the connecting opening to limit the connecting column and further improve the connection stability between the protective net assembly and the fixed column.

[0017] Preferably, a side of the elastic pressing block close to the connecting column is provided with a close-fitting arc surface, and the close-fitting arc surface is in close contact with the outer wall of the connecting column.

[0018] With the above technical solution, the elastic pressing block is provided with a close-fitting arc surface, which can increase the contact surface between the elastic pressing block and the connecting column, thereby improving the limiting effect of the elastic pressing block on the connecting column.
