SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a highway safety barrier for solve current highway safety barrier not only the structure complicated but also the relatively poor problem of effect.

In order to solve the problems, the utility model provides a road safety guardrail, which comprises a substrate, wherein the top of the substrate is provided with a first supporting column and a second supporting column, a moving rod is arranged between the first supporting column and the second supporting column, two ends of the moving rod are both fixedly provided with sliders, the side walls of the first supporting column and the second supporting column are both provided with chutes matched with the sliders, tension springs are both fixedly arranged between the sliders at the same side, one ends of the sliders at the same side opposite to each other are both fixedly provided with compression springs, and one ends of the compression springs far away from the sliders are fixedly connected with the inner walls of the chutes; a plurality of arc-shaped protection plates are uniformly arranged between the moving rods.

The utility model provides a highway safety barrier still has following technical characteristic:

furthermore, a greening box is fixedly arranged at the top of the first supporting column and the second supporting column.

Further, a plurality of rubber bulges are uniformly arranged on the arc-shaped protection plate.

Furthermore, a limit screw is fixedly arranged on the substrate.

Further, the arc-shaped protection plate is made of alloy steel.

Furthermore, the material of carriage release lever is stainless steel pipe.

The utility model discloses following beneficial effect has: when the accident vehicle impacts the arc-shaped protection plate, the vehicle can be buffered for the first time through the deformation of the arc-shaped protection plate; when the arc-shaped protection plates are bent inwards, the arc-shaped protection plates push the movable rods to move back and forth, and the tension springs are stretched, so that the vehicle can be buffered for the second time; when the sliding block moves, the pressing spring can be compressed through the sliding block so as to buffer the vehicle for the third time; by adopting the design, the aim of multistage buffering of accident vehicles can be achieved, the structure is simple, and the anti-collision effect is good.
