The guardrail frame 3 consists of a mounting strip 301, a buffer rail 302, and a reinforcing rail 303. A set of tie rods 3011 are fixedly connected to both sides of the top of the mounting strip 301. The tie rods 3011 facilitate the assembly and disassembly of the guardrail frame 3 and the mounting frame 1. Mounting holes 3012 are provided on both sides of the mounting strip 301 at positions corresponding to mounting hole 104. The mounting strip 301 is bolted to the mounting frame 1 through mounting holes 3012 and 104, thus fixing the guardrail frame 3 to the mounting frame 1. A set of buffer rails 302 are fixedly connected to the bottom of the mounting strip 301 at positions corresponding to the adjacent two sets of mesh frame 2.

[0029] The working process of this utility model is as follows: First, the mounting frame 1 is fixed to the road surface bolts through the fixing holes 1011 on the mounting base 101. The anti-slip pad 1012 enhances the anti-slip performance and stability of the bottom of the mounting base 101 in contact with the road surface. Adjacent sets of mounting frames 1 are connected by connecting blocks 1022 and connecting grooves 1023, improving the connection strength and assembly convenience between the mounting frames 1. The guardrail frame 3 uses the buffer rail 302 to be connected to the connecting strip 203 through the connecting groove 3021, and is inserted into the gap between adjacent sets of mesh frame 2, improving the connection strength between the buffer rail 302 and the mesh frame 2. The reinforcing rail 303 is connected by T-shaped slider 303. 1. It is slidably connected to the T-slot 103 and inserted into the interior of the mounting bracket 1 to improve the connection strength between the guardrail frame 3 and the mounting bracket 1. The bolt passes through the second mounting hole 3012 and is embedded in the first mounting hole 104, so that the mounting strip 301 is bolted to the mounting bracket 1, so that the guardrail frame 3 is fixed on the mounting bracket 1 as a whole. When the car collides with the guardrail as a whole, the unloading roller 3022 buffers and unloads the impact force of the car, so as to avoid the guardrail from deforming and being damaged due to excessive impact force. The reflective warning strip 3023 provides a warning for cars driving at night. The double-layer protective net 201 provides isolation and protection for both sides of the net frame 2, and enhances the structural strength of the net frame 2.
[0030] The entire operation process is simple and convenient. Compared with existing isolation guardrails, this utility model can enhance the buffer performance and impact resistance of the guardrail through design, improve the overall structural strength and protection of the guardrail, and facilitate assembly.
