Abstract

The application relates to a municipal crash barrier, which relates to the field of guardrails and comprises upright posts, upper cross bars, lower cross bars and guardrails, wherein elastic buffer bars are arranged on two opposite sides of each guardrail, a connecting rod is connected to the guardrail in a sliding manner, and the connecting rod is positioned between the elastic buffer bars on two sides and is abutted against the elastic buffer bars. When the automobile bumps the guardrail, the automobile bumps the elastic buffer strip at first for the elastic buffer strip takes place deformation towards the direction that is close to the railing, on the one hand, above-mentioned elastic buffer strip that is bumped returns to the throne elasticity to the automobile, on the other hand, promotes the elastic buffer strip that the connecting rod extrusion is located the railing opposite side after the elastic buffer strip deformation, produces another elasticity that resets and cushions the automobile simultaneously, has improved the buffering effect to the automobile, has reduced the harm that automobile and guardrail received, and then has reduced the harm to driver life safety on the automobile.
