Description

Technical Field

[0002] As a safety protection facility on the side of the highway, highway anti-collision guardrails can provide safety protection for motor vehicles during highway driving. The difference between highway guardrails and other warning and prompting installation facilities is that guardrails absorb impact energy through their own elastic-plastic deformation, friction, and body deformation, thereby reducing the severity of accidents and protecting the safety of people in the car, road buildings, and other objects outside the road.

[0003] The utility model patent with announcement number CN215366984U discloses a deceleration and anti-collision guardrail device for highway traffic safety facility engineering, which belongs to the technical field related to guardrail devices.

The two ends of the limiting connecting rod are installed with connection and fixing components at the connection between the first positioning column and the second positioning column. The buffer and anti-collision components are installed on both sides of the limiting connecting rod. The staff positions the first positioning column and the limiting connecting rod through the first positioning screw and the second positioning screw.
