[0030] A highway guardrail according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0031] Referring to Figure 1 、 Figure 2 and Figure 3 ,a highway guardrail according to an embodiment of the present utility model includes mounting columns 100, cross beams 110, an outer protection assembly 120, and an inner protection assembly 160.

[0032] For the mounting columns 100, at least two mounting columns 100 are provided. The mounting columns 100 are used to be fixed on the ground, so as to facilitate fixing the highway guardrail on the ground, and further make the highway guardrail firm.

[0033] In some specific embodiments, the mounting columns 100 are fixedly installed on the ground by bolts, so as to make the mounting columns 100 more firm.

[0034] In some specific embodiments, a first side support foot and a second side support foot are respectively arranged on one side of the installation column 100 close to the road and on the side away from the road, so that the installation column 100 is more stable.

[0035] For the cross beam 110, the cross beam 110 is arranged between two adjacent installation columns 100, and two ends of the cross beam 110 are respectively connected to the two installation columns 100, so as to conveniently connect and fix two adjacent installation columns 100.

[0036] For the outer protection component 120, the outer protection component 120 is arranged on one side of the cross beam 110, and the outer protection component 120 is used for intercepting and protecting the outside of the road. The outer protection component 120 includes an upper cross bar 130, a lower barrier 140 arranged below the upper cross bar 130, and an adjusting member 150 for adjusting the height of the lower barrier 140.

[0037] It can be understood that the adjusting member 150 adjusts the height of the lower barrier 140, so that the clearance height between the lower barrier 140 and the ground is adjustable. Thus, it is convenient to adjust the clearance between the lower barrier 140 and the ground according to the requirements of the road section or to make the lower barrier 140 fit the ground. Furthermore, animals of different sizes can be effectively intercepted, and the interception effect of the outer protection component 120 on animals outside the road is better.

[0038] In some specific embodiments, the adjusting member 150 is set as a first screw rod. The first screw rod is rotatably connected to the upper cross bar 130, and the first screw rod is threadedly connected to the lower barrier 140. Thus, on the one hand, it is convenient to adjust the height of the upper cross bar 130 by rotating the first screw rod. On the other hand, the threaded connection between the first screw rod and the lower barrier 140 can achieve self-locking between the first screw rod and the lower barrier 140, so that the height position of the lower barrier 140 can be quickly fixed.

[0039] Furthermore, a hand wheel 270 is arranged at the top end of the first screw rod, so as to conveniently rotate the first screw rod.

[0040] In some specific embodiments, a second sliding groove 280 extending vertically is arranged on the side wall of the installation column 100, and the side edge of the lower barrier 140 is accommodated to slide up and down in the second sliding groove 280, so that the lifting of the lower barrier 140 is more stable.

[0041] In some specific embodiments, a second reflective sticker 290 is arranged on the side of the upper cross bar 130 away from the inner protection component 160. Thus, at night, pedestrians outside the road can identify the position of the outer protection component 120 through the second reflective sticker 290, and avoid accidentally hitting the outer protection component 120 at night.

[0042] In some specific embodiments, a planting groove 300 is provided at the top of the upper crossbar 130. The planting groove 300 is used for planting flowers and plants. Thus, by planting flowers and plants in the planting groove 300, the air near the highway guardrail can be purified, the dust concentration near the highway guardrail can be reduced, and at the same time, the highway can be beautified.

[0043] For the inner protection component 160, the inner protection group is arranged on the other side of the crossbeam 110.

The runner 190 is used for supporting the collision source.

[0044] It can be understood that, on the one hand, the runner 190 is rotatably arranged on the mounting frame 170. When the collision source collides with the runner 190, the runner 190 can rotate along the impact direction of the collision source, so that the runner 190 can guide the collision source to deflect along the direction parallel to the length direction of the highway guardrail. Thus, the runner 190 can unload the impact of the collision source and reduce the damage degree of the collision source and the highway guardrail when the collision source collides with the highway guardrail. On the other hand, when the collision source collides with the runner 190, the first spring 180 arranged between the crossbeam 110 and the mounting frame 170 can buffer the impact of the collision source on the highway guardrail. Thus, the damage degree of the collision source and the highway guardrail when the collision source collides with the highway guardrail is further reduced.

[0045] In some specific embodiments, a slide rod 200 is provided on one of the mounting frame 170 and the crossbeam 110, and a slide sleeve 210 is provided on the other of the mounting frame 170 and the crossbeam 110. The slide rod 200 and the slide sleeve 210 are slidably matched. The first spring 180 is sleeved outside the slide sleeve 210. One end of the first spring 180 is connected to the mounting frame 170, and the other end of the first spring 180 is connected to the crossbeam 110. Thus, when the mounting frame 170 moves relative to the crossbeam 110, the slide rod 200 and the slide sleeve 210 can cooperate to guide, and further, the movement of the mounting frame 170 is made more stable. At the same time, the slide sleeve 210 can limit the first spring 180, making the first spring 180 more stable.

[0046] Further, a limiting convex block 220 is provided on the inner wall of the sleeve opening of the slide sleeve 210. The slide rod 200 is provided with a first chute 230 for accommodating the sliding of the limiting convex block 220. A limiting wall 240 is provided at one end of the first chute 230 close to the free end of the slide rod 200. The limiting convex block 220 and the limiting wall 240 are abutted and limited, so as to prevent the slide rod 200 from detaching from the slide sleeve 210. Further, the cooperation between the slide rod 200 and the slide sleeve 210 is made more stable.

[0047] In some specific embodiments, a carbon fiber layer 250 is provided on the outer peripheral surface of the runner 190. The carbon fiber layer 250 is used to abut against the collision source. Thus, the carbon fiber layer 250 has high strength, can protect the runner 190, reduce the risk of the runner 190 being broken by collision, and avoid secondary damage to the collision source caused by the broken runner 190.

[0048] In some specific embodiments, a first reflective sticker 260 is provided on the outer side of the carbon fiber layer 250. Thus, vehicle drivers on the road can identify the position of the inner protection component 160 through the first reflective sticker 260 at night, and avoid accidentally hitting the inner protection component 160 by vehicles on the road at night.
