A road protection fence with a buffer structure

Abstract

The invention discloses a road guardrail with a buffer structure, which comprises a guardrail and a column. Adjacent guardrails are fixedly connected through a connecting plate, a bracket is fixed on the connecting plate, and one end of two long connecting rods is plugged into the bracket And hinged on the bracket, the other ends of the two long connecting rods are respectively hinged with short connecting rods, and a hoop is inserted and fixed on the upper column, and the hoop is composed of two arc-shaped front and rear fixing pieces. , the two ends of the front fixed piece are respectively fixedly connected with the two ends of the rear fixed piece, the two ends of the rear fixed piece are bent to form a ring-shaped positioning sleeve, and the short connecting rod is hinged together through the hinge shaft and the positioning sleeve of the rear fixed piece, A permanent magnet is fixed in the column on the inside of the hoop, and a V-shaped elastic piece is arranged between the two long connecting rods. The guardrail of the invention has a good cushioning effect and can reduce the impact damage caused when the vehicle collides.

Description

Technical field: [0001] The invention relates to the technical field of security products, and more specifically to a road protection fence with a buffer structure. Background technique: [0002] The protective structure of the existing safety fence beside the road is generally a protective plate, and the protective plate is mostly bent from metal materials to form an arc-shaped plate structure. Although the protective plate of the arc-shaped plate structure can provide a certain buffer force to reduce impact damage , But its buffering distance is relatively short, and the buffering strength is relatively small. When vehicles hit the barrier, more serious damage will often occur. Summary of the invention: [0003] The purpose of the present invention is to address the shortcomings of the prior art, and provide a road protection fence with a buffer structure, which can provide a good buffer effect and reduce impact damage. [0004] In order to achieve the above objectives, the techn...
