[0002] In order to prevent vehicles from deviating from the road and to separate the area between pedestrians and vehicles, crash barriers are used. Crash barriers are facilities that prevent vehicles from colliding or crossing the boundary, thereby ensuring traffic order and driving safety. However, the length of traditional crash barriers is fixed, and cannot be adjusted according to actual needs after installation, resulting in the need for replacement or adjustment, which increases the workload and cost. In addition, traditional crash barriers are usually not designed with a buffer function. When a vehicle collides with its crash barrier, the impact force cannot be effectively reduced, resulting in greater damage to the vehicle and the guardrail. Utility Model Content

[0013] 1. When installing the guardrail, the user can adjust the length of the guardrail by rotating the knob on the guardrail according to the installation area. This design enables the guardrail to adapt to roads or places with different length requirements, providing greater flexibility and adaptability. In addition, since the guardrail can be adjusted in length during installation, the workload of adjustment or replacement after installation is avoided. The user only needs to adjust the length of the guardrail by turning the knob, which reduces the extra work and time cost. Moreover, adjusting by turning the knob is a simple and convenient operation method that does not require special tools or complicated processes. This makes the installation process more convenient and efficient.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figures 1 to 4 As shown, the utility model provides a municipal road surface design anti-collision guardrail, including two groups of bases 1, and the two groups of bases 1 are provided with a plurality of positioning holes 7 on the sides. Through the positioning holes 7, the bases 1 can be fixed at different positions, so that the installation of the guardrail is more stable and reliable. The user uses the positioning holes 7 to install ground nails adapted to different road conditions to adapt to different sites and road conditions. The design of the positioning holes 7 makes it more convenient to adjust the position of the guardrail. If the position of the guardrail needs to be moved or adjusted, it is only necessary to reselect and insert the ground nails through the positioning holes 7 for fixing, without the need for additional tools or complicated operation steps. The two groups of bases 1 are provided with support rods 3 above, and the tops of the two groups of bases 1 are provided with mounting grooves 2. The two groups of support rods 3 are respectively clamped in the two groups of mounting grooves 2. The bottoms of the two groups of bases 1 are provided with fixing bolts 11. One end of the two groups of fixing bolts 11 passes through the two groups of bases 1 respectively and is clamped at the bottom of the two groups of support rods 3. By clamping the support rods 3 in the mounting grooves 2, the stability of the support rods 3 can be ensured. The use of the bottom fixing bolts 11 can provide additional support and firmness to the support rods 3, preventing the guardrail from shaking or tilting during use. The tops of the two groups of support rods 3 are provided with reflective lights 4, which can reflect ambient light, making the guardrail more noticeable at night or in low light conditions. This improves the visibility of the guardrail to drivers, pedestrians and other road users, effectively reducing the risk of accidents, and the reflective lights 4 do not require independent power supply. They use light from light sources such as vehicle headlights or street lights for reflection, so no additional energy consumption and maintenance are required.

[0024] like Figures 2 to 4 As shown, two groups of connecting rods 8 are arranged between the two groups of support rods 3, and movable rods 6 are inserted into both ends of the two groups of connecting rods 8. Multiple mounting holes 5 are opened on both sides of the two groups of support rods 3, and the multiple groups of movable rods 6 are connected to the two groups of support rods 3 through the multiple groups of mounting holes 5 opened on the corresponding sides of the two groups of support rods 3. The mounting holes 5 opened on both sides improve the connectivity of the guardrail and optimize the operation mode during its connection. Slide grooves 9 are opened on the two groups of connecting rods 8, and multiple groups of knobs 10 are opened on the two groups of connecting rods 8. One ends of the multiple groups of knobs 10 pass through the two groups of slide grooves 9 respectively and are clamped on one ends of the multiple groups of movable rods 6. When installing the guardrail, the user can rotate the knob 10 on the guardrail according to its installation area to adjust the length of the guardrail. This design enables the guardrail to be The invention can adapt to roads or places with different length requirements, provide greater flexibility and adaptability, and because the guardrail can be adjusted in length during installation, the workload of adjustment or replacement after installation is avoided. One end of the two groups of support rods 3 is provided with a protective plate 15, and one end of the protective plate 15 is provided with two groups of positioning rods 16. A connecting seat 17 is provided between the two groups of positioning rods 16, and a telescopic rod 13 is provided between the connecting seat 17 and the support rod 3. A placement groove 12 is opened at one end of the support rod 3, and one end of the telescopic rod 13 is clamped in the placement groove 12, and the other end is clamped in the connecting seat 17. Both ends of the placement groove 12 are clamped with springs 14. After being hit, the protective plate 15 will push the telescopic rod 13 to shrink, and the two groups of positioning rods 16 will squeeze the two groups of springs 14, thereby producing a buffering effect. This design can absorb part of the collision force, reduce the impact of vehicles and guardrails, thereby reducing the damage and loss caused by accidents, and provide more reliable safety protection. The length of the telescopic rod 13 can be adjusted according to actual needs to adapt to the requirements of different scenes or roads. This makes the guardrail more flexible and adaptable.

[0025] The specific usage and function of this embodiment are as follows:

[0026] When installing the guardrail, the user can rotate the knob 10 on the guardrail according to the installation area to adjust the length of the guardrail. This design allows the guardrail to adapt to roads or places with different length requirements, providing greater flexibility and adaptability. Since the guardrail can be adjusted in length during installation, the workload of adjustment or replacement after installation is avoided. After the adjustment is completed, the user can install the ground nails adapted to different road conditions through the positioning holes 7 on the guardrail base 1 to adapt to different sites and road conditions, thereby installing the guardrail. The design of the positioning holes 7 makes it more convenient to adjust the position of the guardrail. After the guardrail is installed, the support rod 3 of the guardrail is provided with mounting holes 5 on both sides. The user can easily connect the two sets of guardrails through the mounting holes 5 to form a continuous guardrail system of any length and shape. The user can combine, separate and reconfigure the guardrail as needed to adapt to different road layouts and needs.
