[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1. The splicing frame itself is in the shape of a U, so that the splicing frame can be quickly sleeved on the outside of the guardrail body, thereby enabling the subsequent guardrails to be spliced according to requirements and play a blocking role, and when the position of the guardrail body is fixed, the guardrails will not be loose, thereby reducing positional deviation and affecting the blocking effect.

[0015] Further, the second elastic air bag fitted inside the splicing frame can reduce the gap between the guardrail body and the splicing frame, so that when the splicing frame is sleeved on the outside of the guardrail body, the basic position of the guardrail body can be limited, effectively avoiding the problem of up and down shaking of the guardrail body without using a fastening bolt to lock the guardrail body.

By inserting the limiting rod into the inside of the ground, rotating the threaded rod and pushing the sliding block downward, the sliding block pushes the second hinge rod downward when moving downward, and the second hinge rod is hinged with the first hinge rod, so that the first hinge rod passes through the fixed groove from the inside of the limiting rod and extends to the outside of the limiting rod, thereby realizing the positioning of the limiting rod. When the first hinge rod is completely unfolded, directly pulling the limiting rod upward, the angle of the unfolded first hinge rod increases a certain resistance, thereby maintaining the stability of the positioning installation of the supporting rod and increasing the applicability during use.

[0018] Further, the second hinge rod is hinged with the sliding block, so that when the sliding block moves downward, the angles of the upper and lower ends of the second hinge rod are deflected, so that the angle of the first hinge rod is deflected, and the first hinge rod is hinged with the fixed plate, so that the angle of the first hinge rod is also deflected when it is pressed. When the position of the sliding block is fixed, the angle of the second hinge rod and the first hinge rod is also limited due to the distance limitation of the fixed plate and the sliding block, thereby increasing the stability during use.

Figure 1 、 Figure 2 、 Figure 3 and Figure 5 ​

[0028] In this case, the guardrail body 3 is clamped to the inside of the support rod 1, the guardrail body 3 is pushed to the inside of the splice frame 4, and then the fastening bolt 5 is threaded and rotated so that the fastening bolt 5 can lock the position of the guardrail body 3; because the splice frame 4 itself is U-shaped, the splice frame 4 can be quickly sleeved on the outside of the guardrail body 3, and then the subsequent guardrails can be spliced according to the needs and play a blocking role, when the position of the guardrail body 3 is fixed, the multiple guardrails will not be loose, thereby reducing the positional deviation and affecting the blocking effect; and the second elastic air bag 9 fitted inside the splice frame 4 can reduce the gap between the guardrail body 3 and the splice frame 4, so that when the splice frame 4 is sleeved on the outside of the guardrail body 3, the basic position of the guardrail body 3 can be limited, effectively avoiding the problem of the guardrail body 3 shaking up and down without using the fastening bolt 5 to lock the guardrail body 3.
