The invention discloses an anti-rebound safety traffic guardrail. The guardrail comprises two transverse plates which are distributed in parallel up and down, wherein a plurality of vertical plates are fixedly connected between the two transverse plates at equal intervals, a power source cavity and two sliding cavities are formed in each vertical plate, and the two sliding cavities are symmetrically distributed up and down relative to the power source cavity; a pressed box is arranged on the front side of each vertical plate, and iron cores are fixedly connected to inner walls of the front side and the rear side of each pressed box. The guardrail is advantaged in that on one hand, the first spring and the second spring are arranged to weaken the vehicle body speed, and the vehicle body is prevented from being excessively damaged due to rigid contact; on the other hand, an iron core, a first wire, a second wire, a slide rheostat, a contact switch and the like are arranged, so the magnetic attraction force generated by the electromagnet to the vehicle body is gradually increased in the reverse movement process of the vehicle body, elastic potential energy of the first spring and the second spring is counteracted, and secondary traffic accidents are avoided.
本发明公开了一种防反弹安全交通护栏，包括两个上下平行分布的横板，两个所述横板之间等距固定连接有多个竖板，各所述竖板内均开设有一个电源腔与两个滑动腔，且两个滑动腔关于一个电源腔上下对称分布，各所述竖板的前侧均设有受压箱，所述受压箱的前后两侧内壁固定连接有铁芯。优点在于：本发明一方面设置第一弹簧与第二弹簧以削弱车体速度，避免车体发生刚性接触而导致车体过度损坏，另一方面设置铁芯、第一导线、第二导线、滑动变阻器、接触开关等使车体在反向移动的过程中电磁铁对车体产生的磁吸力逐渐增大，从而抵消第一弹簧与第二弹簧的弹性势能，避免发生二次交通事故。
