Detailed ways

The utility model will be further described below in conjunction with the description of the drawings and the embodiments, and the mode of the utility model includes but not limited to the following embodiments.

As shown in Figures 1-2, the utility model provides a highway guardrail with a buffer function, including: a base 1, a support rod 2, a buffer plate 3, a deceleration plate 4, a buffer pad 5, and a buffer belt 6;

As shown in Figure 1, the base 1 is provided with a fixing hole 11, and is connected with the ground by inserting fixing bolts from the fixing hole 11. Both sides of the top surface of the base 1 are fixedly equipped with support rods 2, and the support There are deceleration grooves 21 on the opposite surfaces of the rods 2. The inner wall surface of the deceleration grooves 21 is a frosted plate. A buffer plate 3 is installed between the opposite ends of the support rods 2. The buffer plate 3 is "C" as a whole. Its two sides respectively pass through the deceleration groove 21 and continue to extend. The deceleration plates 4 are installed on the two outer sides of the extension ends. A buffer belt 6 is arranged between the support rods 2. The buffer belt 6 and the inner surface of the buffer plate 3 A buffer pad 5 is provided between the sides. When the vehicle collides with the guardrail, it first abuts against the buffer plate 3 and moves the buffer plate 3 toward the support rod 2 so that the two sides of the buffer plate 3 are in contact with the speed reduction groove 21. The inner surface is constantly rubbed to decelerate the vehicle. When the buffer plate 3 moves, the buffer pad 5 and the buffer belt 6 perform elastic impact, and then the impact force of the vehicle is slowed down by the elastic potential energy, and the vehicle is decelerated twice.
