Background Art

Highway guardrails are a type of equipment used to protect highways and roads. They are usually made of metal and installed on both sides of the road to prevent vehicles from accidentally running off the road or colliding with other obstacles. The main function of highway guardrails is to reduce traffic accidents and protect people's lives. They can reduce the distance and speed of vehicles on the road, thereby reducing the probability and severity of accidents. In addition, highway guardrails can also reduce the noise and air pollution generated by vehicles during driving, improving the driving experience of road users.

In the existing highway guardrail, it generally includes a guardrail body, a connecting rod and a fixed column. Generally, there are two guardrail bodies and a plurality of connecting rods. The two guardrail bodies are connected by a plurality of connecting rods. The ends of the two guardrail bodies are connected to the fixed column by fixing bolts. However, in the existing installation between the guardrail body and the fixed column, multiple people are required to cooperate and manually support the guardrail body so that the fixing hole on one side of the guardrail body corresponds to the position of the mounting hole on the fixed column. Then, the fixing bolt is passed through the fixing hole and extended to the inside of the mounting hole to fix the guardrail body by the fixing bolt. In this process, the guardrail body needs to be manually supported until the other end of the guardrail body is fixed, which makes the overall installation process more cumbersome.

Therefore, it is necessary to provide a new highway guardrail to solve the above-mentioned technical problems.
