[0002] The telescopic guardrails on the edge of the stairs are an important part of the safety protection of the construction site. During the construction process, in order to ensure the safety of the construction workers, it is necessary to set up temporary guardrails on the edge of the stairs to ensure that when the workers go up and down the stairs, there is a certain protection effect on both sides to avoid the occurrence of safety construction.

[0003] Most of the existing stair edge guardrails are temporary guardrails built for the stairs by using steel pipes and binding enclosures. The installation process consumes a lot of manpower and material resources, and the installation process is complicated and time-consuming, resulting in low installation efficiency, which affects the construction progress. In order to increase the structural stability of the guardrail, the guardrail is installed by welding, which makes subsequent disassembly more difficult. Therefore, we propose a telescopic guardrail for the stair edge to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects: the staircase edge telescopic guardrail;

[0012] (1) By arranging a movable structure consisting of a threaded rod, a first connecting block, and a second fixing plate on the supporting column, the second fixing plate can be moved up and down to form a clamping structure with the first fixing plate, so that the supporting column can be fixed on the staircase by the side of the staircase, so that the supporting column of the guardrail can be fixed on the staircase more quickly. At the same time, the second fixing plate can be driven by the transmission rod and the first movable block at the rear side to change the angle, so that it can be suitable for different stair bottom surfaces, thereby improving the applicability of the edge telescopic guardrail. In addition, the first movable block is a movable structure on the transmission rod, which can slide forward to make the first slot on it connected to the sliding rod on the first connecting block, so that the rotation of the second fixing plate is fixed by the buckle structure, thereby improving the stability of the second fixing plate;

[0013] (2) By connecting the rotating shafts at both ends of the telescopic rod between the supporting columns of the telescopic guardrail at the edge, it can be applied to stairs with different height differences. At the same time, because it is a telescopic rod, it can be applied to different stair lengths. The connecting plate on the supporting column is connected to the supporting column through the connecting rotating shaft, so that the supporting column of the telescopic guardrail at the edge can be applied to different corners, thereby improving applicability. The telescopic rod is connected to the second card slot on the movable slot of the connecting plate through the second card block on the connecting rod at both ends, so that the telescopic rod can be quickly disassembled, making installation faster and improving installation efficiency.
