[0001] The utility model relates to the technical field of guardrails, especially to a municipal road guardrail. BACKGROUND

[0002] The municipal road is a road system planned, constructed and maintained by the urban construction department, and is the key of urban traffic and infrastructure construction. The guardrail is used for many reasons. From the traffic safety guarantee, it can separate the traffic flow and prevent the vehicle from crossing the border and colliding. In the traffic order maintenance, it can standardize the traffic behavior and dredge the flow. In the city landscape and environment, it can beautify the image and reduce the influence of dust and noise on the surrounding. The guardrail has important significance for the safety, order and environment of the municipal road.

[0003] The existing guardrail is mostly used in the process of placing a fixed size of the guardrail plate between two columns to achieve the protection requirement. However, when the protection area is large, multiple guardrails need to be set up for protection. However, the existing guardrail cannot be adjusted in size according to the use condition and is not convenient to store, which increases the workload of the staff and reduces the practicability of the guardrail. Therefore, the municipal road guardrail is proposed to solve the above problems. SUMMARY

[0004] In order to make up for the above shortcomings, the utility model provides a municipal road guardrail, which aims at improving the problem that the structure size of the guardrail used in the prior art is fixed and inconvenient to adjust according to the use condition and inconvenient to store.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: a municipal road guardrail, comprising support shell one and support shell two, a protection assembly is installed between the support shell one and the support shell two, a support rod one is fixedly connected to the inner wall of the support shell one, a driving assembly is installed on the upper surface of the support rod one, a support rod two is fixedly connected in the support shell two, a warning light is fixedly connected to the upper surface of the support shell two;

[0006] The protection assembly comprises a connecting block one, the connecting block one is fixedly connected to the outer wall of the support rod one, a rotating plate one is rotatably connected to the outer wall of the connecting block one, a connecting shaft is fixedly connected in the rotating plate one, a rotating plate two is rotatably connected to the outer wall of the connecting shaft, a connecting block two is rotatably connected to the outer wall of the rotating plate two, a threaded sleeve is fixedly connected to the outer wall of the connecting block two, a connecting block four is rotatably connected to the outer wall of the rotating plate two, and a connecting block three is rotatably connected to the outer wall of the rotating plate one.

[0007] Furthermore, the drive assembly includes a lead screw, one end of which is rotatably connected to the upper surface of a support rod, and the other end of which is fixedly connected to a handle.

[0008] Furthermore, both the outer walls of the first and second support shells are fixedly connected to sliding rods, and a warning component is provided between the two sliding rods. A positioning rod is fixedly connected to one side of the outer wall of the first support shell, and a sleeve is fixedly connected to one side of the outer wall of the second support shell. A positioning component is installed on the outer wall of the sleeve.

[0009] Furthermore, the warning component includes a limiting plate, one side of the outer wall of the limiting plate is fixedly connected to one end of the sliding rod, a support box is slidably connected to the outer wall of the limiting plate, a second spring is sleeved on the outer wall of the sliding rod, and a reflective sticker is fixedly connected to the outer wall of the support box.

[0010] Furthermore, the positioning component includes a fixing block, one side of the outer wall of the fixing block is fixedly connected to one side of the outer wall of the sleeve, a T-shaped insert is slidably connected inside the fixing block, a lever is rotatably connected to the outer wall of the T-shaped insert, and a spring is sleeved on the outer wall of the T-shaped insert.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the handle, the lead screw drives the threaded sleeve, which in turn drives the connecting block two to rotate the rotating plate two. This causes the rotating plate one on the outer wall of the connecting shaft to rotate in coordination. Simultaneously, through the coordination of the rotating plate one and the rotating plate two, the connecting block three slides on the outer wall of the support rod two, thereby achieving the effect of adjusting the length of the guardrail and making it retractable, thus improving the practicality of the guardrail.

[0016] 2. In this utility model, by moving the first and second support shells, the sliding rod is stretched and slides inside the support box, thereby achieving the effect of the second tension spring contracting to make the support box stable. At the same time, the reflective sticker can remind people to stay away. Then, by inserting the positioning rod on one side of the first support shell into the sleeve, the guardrail can be quickly installed, thereby improving the practicality of the guardrail.

The rotation mechanism of the screw rod 3 provides an efficient adjustment method, ensuring that users can easily adjust the guardrail. One end of spring 25 is fixedly connected to the inner wall of the support box 24, and the other end of spring 25 is fixedly connected to the outer wall of the limiting plate 23. Under the action of the restoring force, spring 25 helps the limiting plate 23 return to its original position, ensuring that the guardrail can efficiently return to its initial state.

[0029] Working Principle: When the guardrail is needed, first place the device in the area requiring protection. Then, turn the handle 4 to rotate the lead screw 3, which in turn moves the threaded sleeve 6. The movement of the threaded sleeve 6 then rotates the rotating plate 8. The connecting shaft 10 inside the rotating plate 8 then rotates the second rotating plate 9. The interaction between the rotating plates 8 and 9 causes the connecting block 11 to slide against the outer wall of the support rod 13. Finally, the interaction between the rotating plates 8 and 9 allows for adjustment according to usage requirements. The length effect is achieved by moving the sliding rod 22, which in turn causes the spring 25 to extend and retract. At the same time, the reflective sticker 26 can reflect light to remind people. Then, by inserting the positioning rod 16 on one side of the support shell 1 into the sleeve 17 on the other side of the support shell 24, the reaction force of the spring 21 causes the T-shaped insert 19 to be inserted into the positioning rod 16, thus achieving the effect of quickly installing multiple guardrails. When disassembling, by moving the lever 20, the lever 20 causes the spring 21 to retract, causing the T-shaped insert 19 to disengage from the positioning rod 16, thus achieving the effect of quick disassembly. Then, by turning the handle 4 in the opposite direction, the storage effect is achieved.
