[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a road traffic isolation assembly guardrail, comprising two bases 1, each base 1 having a convex groove 2 inside, and a convex slider 3 slidably connected inside the convex groove 2. A right post 4 and a left post 5 are respectively connected to the top of the two convex sliders 3. Multiple guardrail bars 8 are inserted between the right post 4 and the left post 5, and the multiple guardrail bars 8 are all L-shaped. A positioning sleeve 9 is installed on one side of the left post 5 and the multiple guardrail bars 8. A positioning post 10 is connected to one end of the right post 4 and the multiple guardrail bars 8. The positioning post 10 is inserted into the positioning sleeve 9. This insert-type structure facilitates the connection of the right post 4 and the left post 5 with the multiple guardrail bars 8, and allows for the increase or decrease of the number of guardrail bars 8 as needed, adjusting the assembly. The positioning post 10 has a limiting groove 11 inside, and a plug 12 is slidably connected inside the limiting groove 11. One end of the plug 12 abuts against the bottom of the positioning sleeve 9. A telescopic spring 13 is installed inside the limiting groove 11, and one end of the telescopic spring 13 is connected to the other end of the plug 12, allowing the plug 12 to slide into the limiting groove 11, thus preventing the positioning post 10 from being inserted into the positioning sleeve 9. Under the action of the telescopic spring 13, the plug 12 returns to its original position and abuts against the positioning sleeve 9, which helps prevent the positioning post 10 from disengaging. The positioning post 10 has a cylindrical structure, allowing it to rotate and adjust the angle of a single guardrail 8. A damping spring shock absorber 7 is fixedly installed at one end inside the convex sliding groove 2, and one end of the damping spring shock absorber 7 is fixedly connected to the convex slider 3. The right and left pillars 4 and 5 above the two convex sliders 3 are connected to multiple guardrails 8, respectively, facilitating the damping spring shock absorber 7 to buffer the impacts received by the multiple guardrails 8. A first airbag 14 and a second airbag 15 are fitted onto the outer sides of each guardrail 8 to protect them and isolate impacting objects, thus extending their service life. A luminous sticker 16 is affixed to one side of the second airbag 15 to indicate the position of the multiple guardrails 8 in the event of a power outage or insufficient light. The right pillar 4 and left pillar 5 each include a first pillar 41 and a third pillar 51, respectively. A second pillar 42 and a fourth pillar 52 are slidably connected inside the first pillar 41 and the third pillar 51, respectively. The interiors of the second column 42 and the fourth column 52 are respectively provided with multiple first insertion holes 17 and multiple second insertion holes 18. A first bolt 19 and a second bolt 20 are threadedly connected to one side of the first column 41 and the third column 51, respectively. One end of the first bolt 19 and the second bolt 20 are inserted into one of the first insertion holes 17 and one of the second insertion holes 18, respectively, allowing the second column 42 and the fourth column 52 to slide and adjust the height of the right column 4 and the left column 5. As the first bolt 19 and the second bolt 20 rotate, one end of them shifts and inserts into the first insertion hole 17 and the second insertion hole 18, thus fixing the position of the second column 42 or the fourth column 52. The surface of the second column 42 is provided with scale values ​​21 for easy measurement of the height of the right column 4 and the device.Both bases 1 have mounting holes 6 on their interior sides corresponding to the convex grooves 2, facilitating the fixing of the bases 1 to the ground.

[0022] In summary, when using this road traffic isolation guardrail assembly, the bolt 12 on one end of the positioning post 10 of the guardrail 8 is pressed, causing it to slide and retract into the limiting groove 11. Then, the positioning post 10 is inserted into the positioning sleeve 9 on one side of the left post 5. When the positioning post 10 passes through the positioning sleeve 9, the extension spring 13 at the other end of the bolt 12 pushes the bolt 12 back to its original position, causing one end of the bolt 12 to extend out of the limiting groove 11 and abut against the positioning sleeve 9, connecting the positioning sleeve 9 and the positioning post 10 together, thus completing the assembly of the left post 5 and the guardrail 8. Similarly, by repeating the operation, multiple guardrails 8 and right posts can be assembled. 4 are connected together. The cylindrical structure of the positioning column 10 allows the positioning column 10 to rotate within the positioning sleeve 9. The angle of a single guardrail 8 can be adjusted as needed, so that multiple guardrails 8 surround the road. The base 1 at the bottom of the right column 4 and the left column 5 is fixed to the road surface through the mounting hole 6. When multiple guardrails 8 are impacted, the first airbag 14 and the second airbag 15 on the guardrail 8 separate the impacting object. The sides of multiple guardrails 8 and the left column 5 then drive the convex slider 3 in the base 1 to slide. The damping spring shock absorber 7 on one side of the convex slider 3 deforms to buffer the impact.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
