[0016] The following will be combined with the appendix Figures 1-7 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0017] This utility model provides a movable guardrail for the central median green belt of a municipal road. The movable guardrail is installed at the opening of the central median green belt 1, supported by end posts 11. The installation and setting of the movable guardrail are achieved using a movable locking mechanism, avoiding the need for traditional guardrails. This requires digging a pit at the opening of the green belt, pouring C25 concrete to form a post, and then supporting the guardrail on the post. This method is costly, damages the road surface, and is inconvenient to move. Therefore, this utility model provides a movable guardrail for the central median green belt of a municipal road. Figures 2-7 As shown, it can be implemented in the following manner;

[0018] The temporary guardrail is located at the entrance to the central median green belt 1 of the municipal road, and its overall position is as follows: Figures 2-3 As shown, the movable guardrail consists of two sets of symmetrically distributed guardrail units 2; each set of guardrail units 2 has a set of front guardrail frames 3, a set of end guardrail frames 4 and several intermediate guardrail frames 5; the front guardrail frames 3, intermediate guardrail frames 5 and end guardrail frames 4 are connected as a whole by cross-shaped connecting rods 6, and each set of guardrail frames is equipped with rollers 7 at the bottom.

[0019] like Figure 5As shown, iron plate seats 9 are welded and fixed at the middle or upper middle position of the front guardrail frame 3 and the end guardrail frame 4. Movable latches A10 are connected to the iron plate seats 9 of the two sets of front guardrail frames 3 respectively. The movable latches A10 can be movably clamped onto the end posts 11 of the central dividing green belt 1 (e.g., ...). Figures 2-3 As shown), the front ends of the two sets of guardrail units 2 are movably connected to the end posts 11 of the central dividing green belt 1. At the midpoint of the connection between the two sets of guardrail units 2, a movable latch B12 is connected to the iron plate seat 9 of one set of end guardrail frames 4, and a movable lock head 13 corresponding to the movable latch B12 is connected to the iron plate seat 9 of the other set of end guardrail frames 4. The movable lock head 13 has clamping grooves 13A on both sides to facilitate clamping with the movable latch B12 (as shown). Figure 6 , Figure 7 (As shown).

[0020] like Figures 4-5 As shown, each set of guardrails has a frame 8 that is narrower at the top and wider at the bottom, which makes the guardrails more stable. Rollers 7 are installed at the lower wide end of the frame 8. The top of the guardrail is arc-shaped, without any sharp corners or edges, which makes it easy to install sunshade cloth or dustproof cloth on the top without damaging the sunshade cloth or dustproof cloth.

[0021] The implementation process of this application will be described below;

[0022] Preliminary Preparations: Based on the actual dimensions of the openings in the central median green belt of municipal roads, accurately measure the required length and height of the movable guardrails. Determine the quantity and specific dimensions of the front guardrail frame, end guardrail frame, and intermediate guardrail frame in each guardrail unit. Prepare sufficient quantities of front guardrail frame 3, end guardrail frame 4, intermediate guardrail frame 5, as well as cross-shaped connecting rods 6, rollers 7, iron plate bases 9, movable locks A10, movable locks B12, movable lock heads 13, and other components, ensuring that all components are of qualified quality and free from damage or deformation.

[0023] Guardrail Unit Assembly: First, install the rollers 7 at the lower wide end of each guardrail frame 8, ensuring a secure installation and smooth roller rotation. Arrange the front guardrail frame 3, middle guardrail frame 5, and end guardrail frame 4 in sequence, connecting them into a whole through cross-shaped connecting rods 6. The connection points between the connecting rods 6 and each guardrail frame can be secured with bolts to ensure the stability of the connection, making the entire guardrail unit a movable integral structure. Accurately weld and fix the iron plate base 9 at the middle or upper middle position of the front guardrail frame 3 and end guardrail frame 4. During the welding process, ensure that the iron plate base is correctly positioned and firmly welded, without any incomplete welds or detachment.

[0024] The movable lock buckle is installed at the iron plate seat 9 of the two groups of front end guardrail frames 3, respectively, to ensure that the movable lock buckle A can be flexibly moved after installation and can be smoothly clamped on the end column 11 of the central separation green belt 1. The movable lock buckle B 12 is connected at the iron plate seat 9 of one group of end guardrail frames 4, and the movable lock head 13 is connected at the iron plate seat 9 of the other group of end guardrail frames 4, so that the clamping grooves 13A on both sides of the movable lock head 13 are correctly oriented, facilitating subsequent close clamping with the movable lock buckle B 12.

[0025] Overall installation: transport the two groups of assembled symmetrical distributed guardrail units to the passageway of the municipal road central separation green belt 1. Through the movable lock buckle A 10, the front end positions of the two groups of guardrail units are movably connected to the end column 11 of the central separation green belt 1, respectively, the position of the guardrail unit is adjusted to be aligned with the passageway and in a horizontal state. Push the two groups of guardrail units to the middle to make the movable lock buckle B 12 on one group of end guardrail frames 4 cooperate with the movable lock head 13 on the other group of end guardrail frames 4, and embed into the clamping groove 13A of the movable lock head 13, complete the connection of the middle joint of the two groups of guardrail units, and the movable guardrail installation is completed.

[0026] Debugging and checking: after installation, check whether the installation of the entire movable guardrail is firm, whether each connection part is loose. Push the movable guardrail to check whether the roller 7 rolls smoothly, and whether the clamping of the movable lock buckle A 10 and the movable lock buckle B 12 with the corresponding parts is tight. If it is necessary to install sunshade cloth or dustproof cloth, cover the protective cloth on the arc-shaped part at the top of the guardrail frame, check whether the installation is convenient, and whether the protective cloth is damaged by the edges or edges.

[0027] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
