[0002] During municipal engineering, it is necessary to establish a municipal construction guardrail around the construction to demarcate the construction area and isolate and restrict the entry of people or vehicles. In the prior art, a Chinese utility model patent with the publication number: CN219794915U discloses a construction guardrail for municipal engineering. In this utility model, a disassembled assembly method is adopted, the assembly is simple, and during transportation, more guardrails can be stored in the same space, eliminating the need to transport the guardrails to the construction operation area multiple times, thus avoiding the problems of difficult assembly and inconvenient transportation.

[0003] However, the base of this utility model is connected to the support column. Since the base plays a role in supporting the guardrail, the base is relatively heavy. After the base and the support column are connected, the overall weight is relatively heavy, making it inconvenient to carry. Moreover, the municipal construction device is in a crowded environment, and the connection structure needs to be sufficiently stable. In this utility model, the push rod is in the upper position and is extremely easy to be accidentally touched or pressed by personnel, resulting in structural loosening and detachment, so improvement is needed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a municipal construction guardrail with simple assembly, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0024] As Figure 1 ,Figure 4 , Figure 5 and Figure 6 As shown in Figure 4 , Figure 5 and Figure 6 , a screw rod 9 is movably installed in a column 2. A limiting plate 10 is fixedly connected to the lower part of the screw rod 9. A pressing block 13 is movably installed at the upper part of the screw rod 9. A slot 23 and a screw hole 24 are formed in a base 1. The screw hole 24 is located below the slot 23 and the screw hole 24 communicates with the slot 23. The column 2 is movably installed in the slot 23. The lower end of the screw rod 9 is movably installed in the screw hole 24. A bearing 12 is movably installed at the central position of the pressing block 13. The pressing block 13 is movably installed with the screw rod 9 through the bearing 12. First inclined surfaces 14 are fixedly connected to both sides of the pressing block 13. A top cover 11 is fixedly connected to the upper end of the screw rod 9. By rotating the screw rod 9 downward, the lower end of the screw rod 9 is inserted into the screw hole 24 of the base 1. By rotating the screw rod 9, the screw rod 9 fixedly connects the column 2 and the base 1. When the screw rod 9 moves downward, the pressing block 13 presses the fixing blocks 16 on both sides, so that the fixing blocks 16 move out of the connecting frame 15 and move to a position above the guardrail plate 3, thereby fixing the guardrail plate 3 and making it unable to move upward, making the overall structure of the guardrail more stable.

[0025] It should be noted that the present utility model is a municipal construction guardrail with simple assembly. The guardrail is divided into three parts: a base 1, a column 2 and a guardrail plate 3, which makes the guardrail easy to transport and carry. After placing the base 1 in a suitable position, the column 2 is inserted into the slot 23 of the base 1. The first card slots 5 and the second card slots 6 on both sides of the guardrail plate 3 are installed with the first card plates 7 and the second card blocks 8 on the column 2 respectively. During the installation process, since the spring 22 pushes the second connecting plate 20 to the side, the fixing block 16 fixedly connected to the second connecting plate 20 contracts inward in the connecting frame 15, so as not to block the connection between the guardrail plate 3 and the first card plate 7. The guardrail plate 3 is installed with the first card plate 7 through the first card slot 5, and the second card slot 6 is installed with the second card block 8, so that the guardrail plate 3 is clamped between two columns 2. At this time, both the guardrail plate 3 and the column 2 are easily pulled out upward, and the structure is not stable. Therefore, the screw rod 9 is rotated downward through the top cover 11, so that the lower end of the screw rod 9 is inserted into the screw hole 24. When rotating downward and moving, the pressing block 13 at the upper part of the screw rod 9 moves downward synchronously. The first inclined surfaces 14 on both sides of the pressing block 13 squeeze the fixing blocks 16, so that the fixing blocks 16 move outward in the connecting frame 15, and the second connecting plate 20 moves synchronously on the sliding rod 21, compressing the spring 22. When the limiting plate 10 at the lower end of the screw rod 9 contacts the inner bottom wall of the column 2, stop rotating the screw rod 9, so that the screw rod 9 fixedly connects the column 2 to the base 1. The pressing block 13 on the screw rod 9 pushes out the fixing block 16, and the fixing block 16 moves to a position above the guardrail plate 3, thereby preventing the guardrail plate 3 from moving upward, making the guardrail plate 3 and the column 2 more fixed, and the overall structure of the guardrail is more firmly connected and not easy to loosen or fall off.
