[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] Example: Figure 1-5 As shown, this utility model provides a technical solution for a foldable municipal engineering construction guardrail, comprising two mounting rods 1, with multiple protective rods 2 arranged between the two mounting rods 1. Limiting grooves are evenly distributed at the ends of the protective rods 2, and locking rods 4 are located inside the limiting grooves. Two adjacent locking rods 4 contact each other, facilitating the folding and securing of the unfolded protective rods 2. The multiple protective rods 2 are hinged together. Spring telescopic rods 3 are installed at both ends of each protective rod 2 via screws. The ends of two adjacent spring telescopic rods 3 are connected by locking rods 4. One end face of a mounting rod 1... Both ends are fitted with spring telescopic columns 6 by screws. A limiting groove is opened at the position of the limiting rod 5 on one mounting rod 1. The end of the limiting rod 5 is opened with an arc angle. The outer diameter of the limiting rod 5 is equal to the inner diameter of the limiting groove to ensure the stability of the connection between the two mounting rods 1. A locking block 7 is installed at one end of the spring telescopic column 6 by screws. The other mounting rod 1 has a limiting rod 5 welded to both ends on one side. A locking groove 8 is opened at one end of the bottom surface of the limiting rod 5. The locking groove 8 and the locking block 7 are positioned corresponding to each other. The end of the locking block 7 is opened with an inclined angle to facilitate pushing the locking block 7 to move and to facilitate moving the locking block 7 into the locking groove 8. A spring damper 9 is installed on both ends of a mounting rod 1 by screws. A mounting block 10 is installed on one end of the spring damper 9 by screws. A rotating shaft 11 is rotatably connected between the two mounting blocks 10. A drive shaft 12 is welded to the top of the rotating shaft 11. The drive shaft 12 is connected to the mounting block 10 by a return spring 15. A protective cloth 13 is wrapped around the outside of the rotating shaft 11. A magnetic rod 14 is sewn to one end of the protective cloth 13. The magnetic rod 14 and the mounting rod 1 attract each other, which facilitates the fixation of the protective cloth 13 after it is unfolded.

[0016] After moving the guardrail to a suitable position, the personnel unfold guardrail 2, causing the two adjacent guardrails 2 to rotate. After unfolding the guardrail 2, the personnel then extend the spring telescopic rod 3, moving the locking rod 4 into the interior of the adjacent guardrail 2, thereby fixing the guardrail 2. This facilitates the unfolding and folding of the guardrail, reducing the space occupied by the guardrail when not in use and improving space utilization. When multiple guardrails need to be connected, the personnel move the limiting rod 5 on one mounting rod 1 into the interior of another mounting rod 1. During this process, the spring telescopic column 6 first compresses and then extends, causing the locking block 7 to move to... Inside the slot 8, two mounting rods 1 are connected, improving the efficiency of connecting multiple guardrails and facilitating the splicing of multiple guardrails. After the guardrail is unfolded, the personnel pull the protective cloth 13, causing the magnetic rod 14 to be attracted and fixed to one of the mounting rods 1. The protective cloth 13 protects the guardrail 2. When external objects hit the guardrail 2, the impact force is buffered by the spring damper 9, further protecting the guardrail and thus increasing its service life. When the guardrail is not in use, the magnetic rod 14 is detached from the mounting rod 1, at which point the return spring 15 returns to its original position, and the protective cloth 13 can be rolled up.

[0017] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
