[0007] A connecting plate is arranged on the outer side of the column, and the connecting plate is fixedly connected to the upper surface of the guardrail foundation. A side surface of the connecting plate is provided with a plurality of sliding grooves corresponding to the column, and the column is slidably matched with the sliding grooves.

[0008] The outer side surface of the column is provided with a groove, a connecting rod is slidably connected in the groove, one end of the connecting rod is fixedly connected to a fixed block, and the bottom surface of the fixed block is fixedly connected to the upper surface of the guardrail foundation, and the top of the column is fixedly connected to a cross bar; by arranging the connecting plate, the slide groove, the connecting rod, the fixed block and the groove, the shock absorbing effect can be achieved when the column rotates, and the impact force on the column can be reduced.

[0009] A support frame is fixedly connected to one side of the guardrail foundation, and two groups of support frames are provided, and a protective net is installed between the two groups of support frames.

[0010] The outer sides of the rolling roller and the semicircular protrusion are both provided with rubber sleeves; by providing the rolling roller and the semicircular protrusion and providing the rubber sleeves thereon, it is possible to effectively reduce the impact force when an out-of-control vehicle hits the guardrail.

[0011] The utility model has the following beneficial effects:

[0012] The utility model provides rolling rollers, rotating rods, connecting balls, connecting rods and linkage rods. When an out-of-control vehicle hits the guardrail, the impact rolling rollers enable the column to rotate in a direction close to or away from the center of the road under the cooperation of the rotating rods, connecting balls, connecting rods and linkage rods, thereby reducing the reaction force of the column on the out-of-control vehicle; by providing connecting plates, sliding grooves, connecting rods, fixing blocks and slots, a shock-absorbing effect can be achieved when the column rotates, thereby reducing the impact force on the column; by providing rolling rollers and semicircular protrusions, and by providing rubber sleeves thereon, the impact force can be effectively reduced when the out-of-control vehicle hits the guardrail.
