DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0020] As Figure 1 , Figure 2 and Figure 3 shown, the highway isolation guardrail includes support rods 1, mounting plates 2 and buffer blocks 3, and is characterized in that: the two support rods 1 are vertically arranged on the left and right, a cross bar 4 is fixedly arranged between the support rods 1, a plurality of mounting plates 2 are horizontally arranged and fixedly arranged on the front surface of the cross bar 4, rectangular grooves 21 are formed in four directions on the front surface of the mounting plate 2, guide rods 5 are fixedly arranged within the rectangular grooves 21, sliders 6 are slidably arranged on the guide rods 5, springs 7 are fixedly arranged between the inner sides of the sliders 6 and the rectangular grooves 21, the buffer blocks 3 are arranged in front of the mounting plates 2, inclined and hinged connecting rods 8 are arranged between the four sides of the buffer blocks 3 and the sliders 6 respectively, and rubber blocks 9 are fixedly embedded in the front surfaces of the buffer blocks 3.

[0021] Among them, a base 10 is fixedly arranged at the lower end of the support rod 1. Connecting holes are formed at the four corners of the base 10 and are installed through bolts 101; first connecting seats 31 are fixedly arranged on the four sides of the back surface of the buffer block 3, second connecting seats 61 are fixedly arranged on the slider 6, and both ends of the connecting rod 8 are hinged between the first connecting seat 31 and the second connecting seat 61 through a rotating shaft; the spring 7 is sleeved on the guide rod 5; a fluorescent coating strip 91 is arranged on the front surface of the rubber block 9.

[0022] Regarding the isolation guardrail for roads mentioned in the present utility model, during its specific use, a base 10 is fixedly arranged at the lower end of the support rod 1. Connecting holes are formed at the four corners of the base 10 and are installed on the ground through bolts 101. When a vehicle hits, the rubber block 9 on the front surface of the buffer block 3 can first buffer the vehicle impact. Inclined and hinged connecting rods 8 are respectively arranged between the four sides of the buffer block 3 and the slider 6.
