Road column provided with hook and having buffering function

Abstract

The invention belongs to the technical field of highway safety road columns and particularly relates to a road column provided with a hook and having a buffering function. The road column comprises a swing shaft, an air bag, a column first flat plate, a servo motor, a pneumatic switch, the hook, a telescopic pressurizing mechanism and the like. The air bag is installed between a column first vertical plate and a column fourth vertical plate. When a vehicle collides with a safety post, the column first vertical plate is collided and deforms, the air bag is extruded, high-pressure air in the air bag enters an annular cylinder through an annular cylinder air inlet, the swing shaft starts to rotate, and the hook installed on the swing shaft penetrates through the column first flat plate and hooks a vehicle front machine cover. One end of the telescopic pressurizing mechanism is connected with the safety post, the telescopic pressurizing mechanism can have a buffering function, and high-pressure air is provided. The road column is simple in structure, when the vehicle collides with the road column, the effective buffering function can be achieved due to cooperation of the safety post and the telescopic pressurizing mechanism, and the damage degree of the vehicle is reduced. The practicality is high.

Description

technical field [0001] The invention belongs to the technical field of highway safety road piles, in particular to a road pillar with a hook and a buffer function. Background technique [0002] At present, road piles in urban roads and public places are generally relatively hard, and there is no buffer mechanism. For those who are not familiar with the road conditions or the vehicle is out of control, the vehicle accidentally hits the road pile, which will cause personal or economic losses. When the vehicle is traveling at a high speed, once it hits the road pile, it will cause a serious accident. Some anti-collision bollards are equipped with elastic ropes in their chassis, which will automatically return to their original appearance after being bumped, but they have a weaker blocking effect on out-of-control vehicles. [0003] The present invention designs a road post with a hook and a buffer function to solve the above problems. Contents of the invention [0004] In o...
