[0032] Example 1

[0033] See also Figure 1-Figure 3 This embodiment provides a municipal road guardrail, which solves the problem of cumbersome disassembly and assembly work caused by bolting of the posts and guardrails of the existing guardrails through the plug-in combination configuration of the posts and guardrails.

[0034] In this embodiment, the municipal road guardrail includes a column 10 and a guardrail 20. A first plug-in portion 21 is provided at one end of the guardrail 20, and a second plug-in portion 22 is provided at the other end. The first plug-in portion 21 defines a limiting cavity 23 that allows the second plug-in portion 22 to be inserted. The column 10 defines a plug-in cavity 13 that allows the first plug-in portion 21 to be inserted. The top of the column 10 is screwed with an end cover 12 for tightening the first plug-in portion 21 and the second plug-in portion 22.

[0035] In this embodiment, the guardrails 20 on both sides of the column 10 are connected as one by plugging and fitting the first plug-in portion 21 and the plug-in cavity 13, and the second plug-in portion 22 and the limiting cavity 23. The end cover 12 designed in conjunction with the guardrail 20 can restrict the guardrail 20 inside the column 10, making it easier to disassemble and assemble the guardrail 20 and the column 10.

[0036] It should be noted that a base 11 is fixed to the bottom of the column 10. After the base 11 is fixed to the road surface, the stability of the column 10 can be guaranteed. As an example, the base 11 is bolted to the road surface; the column 10 is constructed as a whole into a hollow cylindrical shape, and the inner cavity of the column 10 forms a plug-in cavity 13. At the same time, avoidance grooves 14 are opened on both sides of the column 10. The avoidance grooves 14 extend along the axial direction of the column 10, and the avoidance grooves 14 pass through the top surface of the column 10; the end cover 12 is integrally sleeved on the outside of the column 10, and the end cover 12 is screwed on the top of the column 10. A limit column 15 is provided inside the end cover 12, and the limit column 15 extends into the plug-in cavity 13, and the limit column 15 and the plug-in cavity 13 are coaxially arranged.

[0037] In addition, the guardrail 20 is arranged as a whole between two adjacent columns 10, and a first plug-in portion 21 is provided at one end of the guardrail 20, and the first plug-in portion 21 is constructed as a whole into a cylindrical shape that matches the shape of the plug-in cavity 13. As an example, the outer diameter of the first plug-in portion 21 is equal to the diameter of the plug-in cavity 13. At the same time, the first plug-in cavity 21 defines a limiting cavity 23, and the limiting cavity 23 is constructed as a circular hole coaxially arranged with the first plug-in portion 21. A clearance groove 24 that is connected to the limiting cavity 23 is also provided on the first plug-in portion 21. The clearance groove 24 extends along the axial direction of the first plug-in portion 21, and the clearance groove 24 is arranged on the side opposite to the guardrail 20; a second plug-in portion 22 is provided at the other end of the guardrail 20, and the second plug-in portion 22 is constructed as a whole into a cylindrical shape that matches the shape of the limiting cavity 23. As an example, the outer diameter of the second plug-in portion 22 is equal to the diameter of the limiting cavity 23.

[0038] During installation, first insert the first plug-in part of the first guardrail into the plug-in cavity of the column, and then insert the second plug-in part of the second guardrail into the limiting cavity on the first plug-in part of the first guardrail. At this time, the first guardrail and the second guardrail are respectively placed on both sides of the column, and the second plug-in part and the first plug-in part form a snap-fit ​​fit, so that the first guardrail and the second guardrail are connected as a whole; finally, the end cover is screwed onto the top of the column until the limiting column on the end cover abuts against the top surfaces of the first plug-in part and the second plug-in part. At this time, the limiting column can limit the first guardrail and the second guardrail inside the column, ensuring the stability of the connection between the guardrail and the column.

[0039] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
