[0027] A mounting device, which is arranged on the sliding mounting ring 6 and is used for quickly disassembling and installing the guardrail 3;

[0028] The dustproof device is arranged on the mounting annular block 2 and is used to prevent dust and debris from entering the embedded mounting box 1 .

[0029] Furthermore, a through hole is provided at the bottom of the inner cavity of the embedded installation box 1 , the bottom of the embedded installation box 1 is a conical structure, and a threaded groove is provided at the lower end of the side surface of the embedded installation box 1 .

[0030] Furthermore, the installation device includes a rotating ring 4 and a limiting rod 7. The lower end of the side of the guardrail 3 is threadedly connected to the rotating ring 4 corresponding to the upper threaded groove portion of the mounting ring block 2, and the side of the sliding mounting ring 6 is hinged with three limiting rods 7 arranged equidistantly in a ring shape.

[0031] Furthermore, one end of the three limit rods 7 away from the sliding mounting ring 6 is rotatably connected to the sliding wheel 8, the lower end of the side of the guardrail 3 is fixedly connected to the limit ring 9, the side of the limit rod 7 close to the guardrail 3 is fixedly connected to the support plate 10, and the side of the support plate 10 away from the sliding mounting ring 6 is attached to the side of the guardrail 3.

[0032] Furthermore, the upper and lower surfaces of the support plate 10 corresponding to the ends away from the guardrail 3 are smooth curved surfaces.

[0033] Furthermore, three annular slots 11 are provided on the inner wall of the mounting annular block 2 , and the width of the three slots 11 is greater than the width of the limiting rod 7 .

[0034] Furthermore, the dustproof device includes a dustproof plate 12 and a clamp spring 13. A dustproof plate 12 is hinged between each two slots 11 corresponding to the top of the inner wall of the mounting annular block 2, and a clamp spring 13 is movably sleeved at the corresponding hinged positions on the lower surfaces of the three dustproof plates 12.

[0035] Working principle: First, on the ground or wall of the area that needs to be protected, a pre-buried installation box 1 is pre-buried so that the installation ring block 2 is exposed on the surface of the ground. When the guardrail needs to be installed, the lower end of the guardrail 3 is first inserted into the installation ring block 2, so that the three limit rods 7 are inserted into the pre-buried installation box 1 through the installation ring block 2. When the lower end of the guardrail 3 is inserted through the installation ring block 2, it enters the inner cavity of the pre-buried installation box 1 by squeezing the dustproof plate 12. When the bottom of the guardrail 3 is against the bottom of the inner cavity of the pre-buried installation box 1, the rotating ring 4 at the lower end of the guardrail 3 is rotated, and the rotating ring 4 is rotated in the threaded groove on the guardrail 3 to make the guardrail 3 move downward horizontally, and the sliding installation ring 6 is squeezed downward by the rotating ring 4, so that it is hinged with the sliding installation ring 6 When the guardrail 3 needs to be removed, the three limit rods 7 are moved downward and the sliding wheel 8 of the port is squeezed. The pressure of the sliding wheel 8 on the top drives the limit rod 7 to expand. After expansion, the fixing is completed. After multiple devices are installed, the protection net can be hung on the protection net installation ring 5 between every two devices; when the protection railing 3 needs to be removed, only the rotating ring 4 is rotated in the opposite direction so that the rotating ring 4 releases the pressure on the sliding installation ring 6, and the protection railing 3 is pulled upward to make the limit rod 7 expanded at the lower end of the protection railing 3 retract, and then move out of the inner cavity of the embedded installation box 1 through the installation annular block 2; after the protection railing 3 is pulled out, the three dustproof plates 12 rebound upward under the pressure of the clamping spring 13, so that the three dustproof plates 12 are closed, and dust and debris can be prevented from entering the embedded installation box 1 in the uninstalled state.
