Abstract

The invention discloses a traffic guard railing which comprises bases. First support rods are fixedly connected to the upper sides of the bases, second support rods are arranged on the upper sides ofthe first support rods, first transverse rods are connected to the upper sides of the second support rods, second transverse rods are connected to one sides of the second support rods, first connection rods are fixedly connected between the first transverse rods and the second transverse rods, bearings sleeve the first connection rods, and rubber rollers are arranged on the outer sides of the bearings. By the arrangement of pull rings and springs, the movable connection between the first support rods and the second support rods also can effectively decompose impact force generated by collision; by the arrangement of second connection rods and limit clamp blocks, it is avoided that the first support rods and the second support rods are separated due to too large impact force; by the arrangement of first connection bases, first clamp blocks, second connection bases and second clamp blocks, free transverse movement between the first transverse rods and between the second transverse rods is realized, and impact can be effectively buffered.
