Detailed Embodiments

[0018] Please refer to Figures 1 to 3 , a guardrail for highway maintenance, including a primary guardrail 1, the primary guardrail 1 includes a guardrail frame 2 in a rectangular frame structure and a blocking rod 3 arranged in the guardrail frame 2; secondary guardrails 4 are arranged on both sides in the length direction of the primary guardrail 1; and the structures and functions of the two secondary guardrails 4 are the same;

[0019] The secondary guardrail 4 includes a shaft rod 5, a fixed seat 6, a movable seat 7, and a telescopic rod 8; the shaft rods 5 are symmetrically arranged in groups at both ends of one side of the guardrail frame 2, and the shaft rods 5 are vertically arranged; the fixed seats 6 are symmetrically arranged in groups at the upper and lower ends of one of the shaft rods 5, and one side of the fixed seat 6 is fixedly connected to the guardrail frame 2; the movable seats 7 are symmetrically arranged in groups at the upper and lower ends of the other shaft rod 5; there are multiple telescopic rods 8, and all the telescopic rods 8 are longitudinally arranged between the two shaft rods 5;

[0020] The telescopic rod 8 includes a first rod 9 and a second rod 10. A sleeve hole 11 with one end open is arranged inside the first rod 9. One end of the second rod 10 is inserted into the sleeve hole 11, and the opposite ends of the first rod 9 and the second rod 10 are respectively rotatably connected to the outer wall of the shaft rod 5; a bolt 12 is arranged on the first rod 9, through holes 13 adapted to the bolt 12 are opened on the outer walls of the first rod 9 and the second rod 10, and the lower end of the bolt 12 threadedly penetrates through the through holes 13 on the first rod 9 and the second rod 10; the first rod 9 and the second rod 10 are fixed by the bolt 12.

[0021] In this embodiment: When using the guardrail, when the length of the main guardrail 1 is insufficient, according to the needs, one side of the secondary guardrail 4 or the secondary guardrails 4 on both sides can be rotated and opened, which can extend the overall length of the guardrail and expand the protection area; at the same time, one end of the second rod 10 is sleeved in the sleeve hole 11. When the protection of the main guardrail 1 and the secondary guardrail 4 is still insufficient, by adjusting the length of the telescopic rod 8, the overall length of the guardrail can be increased again, and the protection area can be expanded again; through the bolt 12 and the through hole 13, it is further easy to fix one end of the second rod 10 in the first rod 9, avoid the separation of the second rod 10 from the first rod 9, and is easy to control the length of the telescopic rod 8; and the angle of the secondary guardrail 4 and the angle of the main guardrail 1 can be adjusted, and the angle of the guardrail can be adjusted for protection according to the needs, improving the practicability and convenience of the protection;
