The positioning hole 508 is provided inside the second limiting plate 3. The positioning block 509 is installed inside the top cover 507.

[0016] Specifically, through the cooperation of the various structures of the assembly mechanism 5, the entire guardrail can be quickly installed on the stair body 1, and the replacement of the insert rod 4 is convenient.

[0017] exist Figure 1 and Figure 2 In the middle, two support rods 6 are fixedly installed on the top of the first limiting plate 2, and the tops of the two support rods 6 are connected to the second limiting plate 3.

[0018] Specifically, the first limiting plate 2 and the second limiting plate 3 are connected by the support rod 6 to ensure the stability of the second limiting plate 3, thus initially forming the guardrail frame.

[0019] exist Figure 1 and Figure 6 In the first slot 501, the first locking block 502 extends into the interior of the first slot 501 on the side away from the first limiting plate 2, and there are no fewer than three fixing screws 503.

[0020] Specifically, by setting the first slot 501, the two first blocks 502 on the first limiting plate 2 are respectively inserted into the two first slots 501 to initially fix the first limiting plate 2, and then the first limiting plate 2 can be fixed and stabilized by fixing screws 503.

[0021] exist Figure 2 and Figure 3 In the middle, each plug rod 4 has two limiting grooves 506 inside, and the two limiting grooves 506 are located at the top and bottom of the plug rod 4 respectively.

[0022] exist Figure 2 and Figure 3 In the middle, the insertion rod 4 passes through the positioning hole 508 and extends into the interior of the first limiting plate 2, and the top of the positioning block 509 is connected to the inner top wall of the top cover 507.

[0023] Specifically, when installing the insertion rod 4, the insertion rod 4 is inserted through the positioning hole 508 of the second limiting plate 3. At this time, the second locking block 505 and the bottom limiting groove 506 engage with each other to ensure the stability of the insertion rod 4.

[0024] exist Figure 3 and Figure 4 In the middle, the bottom of the second locking block 505 is fixedly connected to the inner bottom wall of the second locking groove 504, and the opposite side of the second locking block 505 and the positioning block 509 respectively engages with each of the two limiting grooves 506 in each group.
