The return spring has the function of returning the road pier.
When the automobile laterally impacts the road pier in the driving process, namely the road pier is laterally impacted, the road pier can be subjected to an impact force along the impact direction, and under the impact force, the road pier can transmit the impact force to the second guide rail under the action of the two second guide blocks and the two second guide grooves formed in the second guide rail, so that the second guide rail swings around the rotating shaft under the action of the shaft sleeve; the second guide rail swings to drive the road pier to swing; when the automobile impacts the road pier, the swing of the road pier is used for buffering the reaction impact force of the road pier on the automobile, so that the damage of the automobile is reduced, and the road pier is protected, so that the road pier can be repeatedly used; meanwhile, the road pier can move along the second guide rail under the action of the impact force, and the warning rod can move out of the outer side of the road pier in the moving process to warn a driver; in the process, the second guide rail can swing to the lower side of the automobile, and because the height of the second guide rail is smaller than the distance between the chassis of the ordinary automobile and the ground, the swing of the second guide rail in the process can not influence the automobile. Under the combined action of these two movements, the road block will move in the direction of impact.
When the road pier needs to be moved to two sides, the road pier is in an initial position, the lower road pier is located in the middle of the second guide rail at the position, the lock trigger rod is just located on the upper side of the driving disc, in the moving process, the lock structure is opened, the baffle is taken off, the lock trigger rod is manually pressed downwards, the lock trigger rod moves downwards to drive the driving disc to move downwards, the driving disc moves downwards to drive the connecting rod to move downwards, the connecting rod moves downwards to drive the spring mounting plate to move downwards, and the spring mounting plate moves downwards to compress the reset spring mounted on the spring mounting plate; the connecting rod moves downwards, on the other hand, the limiting block is driven to move downwards, in the moving process of the limiting block, when the limiting block is completely separated from the limiting teeth arranged on the first guide rail, the limiting teeth lose the constraint on the limiting block, namely the limiting teeth lose the constraint on the second guide rail, the sliding installation block and the road pier, and at the moment, the road pier is manually pushed to move towards two sides; the road pier moves to drive the second guide rail and the sliding installation block to move, namely, the passable route originally limited by the road pier is narrow and wide. According to the invention, the lock trigger rod moves downwards to drive the mounting plate to move downwards, and the mounting plate moves downwards to compress the compression spring; the compression spring is used for returning the lock trigger rod. The return spring plays a role in returning the limiting block.
Compared with the traditional road pier technology, when the front face of the road pier is impacted, the reaction impact force of the road pier on the automobile is buffered by the way pier moving back and forth along the second guide rail when the front face of the automobile impacts the road pier. When the side surface of the road pier is impacted, the impact force of the road pier on the automobile is counteracted by the swing of the road pier and the second guide rail along the rotating shaft to buffer the impact of the automobile on the road pier, so that the damage of the automobile is reduced, and the road pier is protected at the same time, so that the road pier can be repeatedly used; the warning rod is designed, so that a driver can be reminded through the warning rod, and the driver is prevented from continuing to drive forwards after impacting the road pier because the road pier is too low and cannot be timely perceived, and further damage is caused to the vehicle. When the road pier designed by the invention is used for holding activities, the road pier can be automatically adjusted to move to two sides conveniently when an automobile passes through, and the width of the road surface between the road piers is increased.
