When the automobile is in front impact with the road pier in the driving process, namely the road pier is subjected to front impact, the road pier moves forwards or backwards along the second guide rail under the action of the impact force, the road pier moves to drive the second gear arranged on the road pier to move, and because the second gear, the teeth on the first rack plate and the teeth on the second rack plate are just in a meshed state in an initial state, and the first rack plate and the second rack plate are arranged on the second guide rail, the second gear can rotate no matter the road pier moves forwards or backwards; the second gear wheel rotates to drive the first rotating shaft to rotate; the first rotating shaft rotates to drive a second rotating shaft connected with the first rotating shaft through a belt to rotate; the second rotating shaft rotates to drive the first gear to rotate; the first gear rotates to enable the warning rod meshed with the first gear to move upwards so that the warning rod moves out of the upper side of the road pier, and a driver is prompted through the warning rod; when buffering car striking road pier through the removal of road pier, the road pier has reduced the damage of car for the reaction impact of car, has also protected the road pier simultaneously for the road pier can used repeatedly. The first rack plate and the second rack plate have the function of ensuring that the second gear can rotate towards one direction no matter the second gear moves forwards or backwards, namely, the automobile can ensure that the warning rod moves to the upper side of the road pier to warn and remind a driver no matter the automobile impacts the road pier from the front face to the front face or impacts the road pier from the front face to the rear face. 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 at an initial position, the lower road pier at the position is located in the middle of the second guide rail, the lock trigger rod is just located on the upper side of the driving square plate, in the moving process, the lock structure is opened, the baffle plate is taken off, the lock trigger rod is manually pressed downwards, the lock trigger rod moves downwards to drive the driving square plate to move downwards, the driving square plate 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.
The third gear has the effect that when the road pier is impacted by the automobile, the road pier can move along the second guide rail; if the automobile is moved, under the action of the return spring, the road pier can move back along with the automobile to rub with the automobile body, so that the road pier can cause secondary damage to the front side of the automobile and further damage the automobile, under the condition, the road pier is moved to the other side of the first guide rail, at the moment, the lock trigger rod needs to be pushed downwards, but the contact point of the lock trigger rod and the driving square plate is deviated from the center, the driving square plate is clamped to be dead in order to ensure that the driving square plate can vertically move downwards without swinging, so that a third gear is designed, when one side of the driving square plate is pressed to move downwards, the driving square plate moves downwards under the action of the toothed plate arranged on the driving square plate, and a corresponding third gear in the two third gears can rotate; the third gear rotates to drive the third rotating shaft to rotate; the third rotating shaft rotates to drive the other third gear to rotate; another third gear rotates and also can the downstream at the one end that the drive side board does not receive the extrusion under the effect of installing pinion rack on the drive side board, and under the effect of two third gears, the both ends downstream's of drive side board speed is the same, has guaranteed that the drive side board can perpendicular downstream.
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.

In summary, the following steps:
the beneficial effects of the design of the invention are as follows: when the road pier 4 is impacted on the front surface, the road pier 4 moves back and forth along the second guide rail 6 to buffer the reaction impact force of the road pier 4 on the automobile when the automobile impacts the road pier 4 on the front surface. When the side surface of the road pier 4 is impacted, the impact force of the road pier 4 on the automobile is reacted when the automobile impacts the road pier 4 through the swing of the road pier 4 and the second guide rail 6 along the rotating shaft 13, so that the damage of the automobile is reduced, the road pier 4 is protected, and the road pier 4 can be repeatedly used; the warning rod is designed, a driver can be reminded through the warning rod 10, and the situation that the driver continues to drive forwards after impacting the road pier 4 because the road pier 4 is too low and cannot be timely noticed is avoided, so that the vehicle is further damaged. When the road piers 4 designed by the invention are used for holding activities, the road piers 4 can be automatically adjusted to move to two sides so as to facilitate the passing of automobiles, and the width of the road surface between the road piers 4 is increased.
In the invention, in an initial state, the limiting tooth 15 arranged on the first guide rail 5 has a certain limiting effect on the limiting block 20, namely the limiting tooth 15 has a certain limiting effect on the sliding installation block 18, the second guide rail 6 and the road pier 4 and prevents the limiting tooth from moving to the other side of the first guide rail 5; however, when a large impact force is applied, the limiting teeth 15 are extruded into the corresponding tooth sockets 43, and the limitation on the limiting blocks 20 is lost, at this time, the limiting teeth 15 lose the limiting effect on the sliding installation block 18, the second guide rail 6 and the road pier 4, and the sliding installation block 18, the second guide rail 6 and the road pier 4 can slide relative to the first guide rail 5; the large impact force is buffered by sliding.
When the automobile is in front impact with the road pier 4 in the driving process, namely the road pier 4 is in front impact, the road pier 4 moves forwards or backwards along the second guide rail 6 under the action of the impact force, the road pier 4 moves to drive the second gear 12 mounted on the road pier 4 to move, and because the second gear 12, teeth on the first rack plate 11 and teeth on the second rack plate 31 are just in an engaged state in the initial state, and the first rack plate 11 and the second rack plate 31 are mounted on the second guide rail 6, the second gear 12 can be rotated no matter the road pier 4 moves forwards or backwards; the rotation of the second gear 12 drives the first rotating shaft 39 to rotate; the first rotating shaft 39 rotates to drive the second rotating shaft 41 connected with the first rotating shaft through the belt 40 to rotate; the second rotating shaft 41 rotates to drive the first gear 9 to rotate; the first gear 9 rotates to enable the warning rod 10 meshed with the first gear to move upwards, so that the warning rod 10 moves out of the upper side of the road pier 4, and a driver is prompted through the warning rod 10; when buffering car striking road pier 4 through the removal of road pier 4, road pier 4 has reduced the damage of car for the reaction impact of car, has also protected road pier 4 simultaneously for road pier 4 can used repeatedly. The first rack plate 11 and the second rack plate 31 in the invention have the function of ensuring that the second gear 12 can rotate towards one direction no matter the second gear 12 moves forwards or backwards, namely, the automobile can ensure that the warning rod 10 moves to the upper side of the road pier 4 to warn and remind a driver whether the automobile impacts the road pier 4 from the front face or from the back face. The return spring 7 plays a role in returning the road pier 4.
When the automobile laterally impacts the road pier 4 in the driving process, namely the road pier 4 is laterally impacted, the road pier 4 is subjected to an impact force along the impact direction, and under the impact force, the road pier 4 transmits the impact force to the second guide rail 6 under the action of the two second guide blocks 35 and the two second guide grooves 29 formed in the second guide rail 6, so that the second guide rail 6 swings around the rotating shaft 13 under the action of the shaft sleeve 14; the second guide rail 6 swings to drive the road pier 4 to swing; when the automobile impacts the road pier 4, the impact force of the road pier 4 on the automobile is buffered by the swinging of the road pier 4, so that the damage of the automobile is reduced, and meanwhile, the road pier 4 is protected, so that the road pier 4 can be repeatedly used; meanwhile, the road pier 4 can move along the second guide rail 6 under the action of the impact force, and the warning rod 10 can move out of the road pier 4 to warn a driver in the moving process; in the process, the second guide rail 6 swings to the lower side of the automobile, and because the height of the second guide rail 6 is smaller than the distance between the chassis of the ordinary automobile and the ground, the swing of the second guide rail 6 in the process does not affect the automobile. Under the combined effect of these two movements, the road block 4 will move in the impact direction.
