DETAILED DESCRIPTION
[0016] like Figure 1-4 As shown: a multifunctional guardrail comprises two support columns 1 distributed on the left and right, the bottom ends of the support columns 1 are fixedly connected to a base 2, and the two bases 2 are mirror-symmetrical on the left and right; auxiliary struts 17 are fixedly connected to the two ends of the opposite side walls of the base 2, and slide grooves 3 are provided on the opposite side walls of the two support columns 1, and the cross-section of the slide grooves 3 is convex, and two sliders 4 are slidably engaged inside the slide grooves 3, and the sliders 4 are convex, and the sliders 4 match the slide grooves 3, and a plurality of connecting mechanisms 1 and rotating connecting mechanisms 2 are arranged between the two support columns 1, and the rotating connecting structure 2 is staggeredly distributed with the rotating connecting mechanism 1, and the connecting mechanism 1 is connected with the rotating connecting mechanism 2, and the upper and lower rotating connecting mechanisms 1 are located on the same axis, and the top and bottom of the left and right sides of the rotating connecting mechanism 2 are rotatably connected with connecting rods 2 15, and the ends of the four connecting rods 2 15 away from the rotating connecting mechanism 2 are respectively rotatably connected to the four rotating connecting mechanisms 1, and the ends of the two connecting rods 2 15 on the left and right sides are respectively rotatably connected to the upper and lower sliders 4.
[0017] The rotating connection mechanism 1 includes an intermediate shaft 16, the outer wall of the intermediate shaft 16 is rotatably sleeved with a slip ring 17 and two slip rings 28, the slip ring 17 is located between the two slip rings 28, the right outer wall of the slip ring 17 is fixedly connected with a connecting ear 19, the connecting ear 19 is gap-matched with the outer walls of the two slip rings 28, the left outer walls of the two slip rings 28 are fixedly connected to the upper and lower ends of the connecting ear 20, the connecting ear 20 is gap-matched with the outer wall of the slip ring 17, and the upper and lower ends of the connecting ear 19 and the connecting ear 20 are respectively rotatably connected to one end of the connecting rod 2 15.
[0018] The rotating connection mechanism 2 includes an intermediate shaft 2 11, a slip ring 3 12 and a slip ring 4 13. The two rotating connection mechanisms 2 are symmetrically arranged up and down. The outer wall of the upper intermediate shaft 2 11 is rotatably sleeved with the slip ring 3 12 and the slip ring 4 13. The slip ring 3 12 is at the lower part of the slip ring 4 13. The outer walls of the slip ring 3 12 and the slip ring 4 13 are fixedly connected with connecting ears 3 14, and each connecting ear 3 14 is rotatably connected to the other end of the connecting rod 2 15 respectively.

[0021] When in use, the two support columns 1 are pulled apart, and the connecting rod 2 15 moves as the distance between the two support columns 1 is pulled apart. The connecting rod 2 15 rotates with the connecting ear 1 9, the connecting ear 2 10 and the connecting ear 3 14 as the center, so that multiple connecting rods 2 15 can be telescoped and expanded. The connecting rods 2 15 adjacent to each other on the left and right can be rotated with the intermediate shaft 1 6 or the intermediate shaft 2 11 as the center to adjust the angle, and can be formed into a circle, rectangle or polygon according to actual use requirements. When a longer guardrail is needed, multiple guardrails can be used together, and the limiting sleeve 16 can be sleeved between the top ends of two adjacent support columns 1 to limit the position between the guardrails, which has a wider range of applications.
