Further, the upper end shape of stopper 28 is cuboid or square, the lower extreme of stopper 28 is provided with two relative inclined planes, just the lower extreme width of stopper 28 diminishes progressively, the one end of trigger lever 27 with the inclined plane contact, stopper 28 lower extreme and two corresponding both sides face sliding connection in adjacent two sides in inclined plane and the constant head tank 5. In some embodiments of the present invention, two opposite right-angled edges of the lower end of the limiting block 28 are respectively provided with an inclined surface, and two side surfaces of the lower end of the limiting block 28, which are provided with the inclined surfaces, are respectively matched with two side surfaces of the positioning slot 5. Preferably, the inclined plane is inclined at an angle of substantially 45 degrees with respect to the ground, and when the trigger rod 27 generates a pushing force on the inclined plane at the lower end of the limit block 28 along the third sliding groove 12, the pushing force generates two component forces on the inclined plane, which are substantially parallel to the ground and vertically face upward, respectively, so as to push the limit block 28 to move forward or backward along the limit groove 8 and the positioning groove 5 to move upward or downward, respectively, because the pushing force is substantially parallel to the ground. When the limiting block 28 moves upward, the limiting block 28 generates upward thrust to the second limiting spring 29, and at this time, the limiting block 28 also moves upward into the positioning groove 5, so that the limitation of the positioning groove 5 on the expansion plate 4 is removed, and the expansion plate 4 moves back and forth along the expansion groove 7 under the forward and backward pushing of the safety post 3 by external force.

Further, the number of the road pillars is at least two, the two road pillars are symmetrically arranged relative to the road surface, and the internal structures of the two road pillars are symmetrical relative to the center of the road surface. The road columns comprise a first road column 1 and a second road column 2, wherein the first road column 1 and the second road column 2 are symmetrically arranged on the ground at two sides of the intersection, so that the function of limiting the width of the road is achieved.

In some embodiments of the invention, when the bollard is in a normal state, in particular, when a non-bollard administrator pushes the safety bollard 3 by hand, the safety bollard 3 is caused to have a tendency to swing about the central axis of the base 18, so that the safety post 3 drives the limit pin 24 through the expansion plate 4, the transition block 6 and the rotation round block 13 to have a tendency of swinging around the central axis of the base 18, since the stopper pin 24 is caught in the second toothed cut 22 and the elastic coefficient of the first stopper spring 25 is large, at this time, since the first stopper spring 25 is hardly contracted, so that the stopper pin 24 is hardly affected by an external force, and thus the inclined surface of the second toothed cut 22 still restricts the swing of the stopper pin 24, so that the safety post 3 does not swing around the central axis of the base 18 under the influence of human force.

In another embodiment of the present invention, when the safety post 3 needs to be moved, since the safety post 3 cannot be moved in the direction of the both sides of the road or the center of the road by human power, since the manual moving groove 11 is locked by a locking method, a manager of the safety post, that is, a manager having the authority of the key locked in the manual moving groove 11, opens the manual moving groove 11 by using the key, so that the manager of the safety post can pull the manual lever 30 by hand, and the manual lever 30 drives the trigger lever 27 to slide in the direction of the safety post 3. Specifically, one end of the trigger rod 27 located in the limiting groove 8 acts on one inclined surface of the limiting block 28, so that the limiting block 28 moves upward, the two side surfaces of the limiting block 28 simultaneously release the limitation on the two side surfaces of the limiting groove 8, then the manager of the guidepost pushes or pulls the safety post 3 with hands, at this time, one inclined surface of the limiting block 28 acts on the notch edge of the limiting groove 8, under the action of the pushing force or the pulling force of the manager, the expansion plate 4 intends to contract into the expansion groove 7 or stretch out of the expansion groove 7, the notch edge of the limiting groove 8 acts on the inclined surface of the limiting block 28, so that the limiting block 28 slides upward along the inner wall of the positioning groove 5, at this time, the second limiting spring 29 is compressed, and the limiting block 28 further releases the limitation on the limiting groove 8, when the manager of the road pillar continues to push or pull, the expansion plate 4 contracts or elongates, the safety pillar 3 moves towards both sides of the road or towards the center of the road, when the safety pillar 3 needs to be reset, the manager of the road pillar releases his hands, the expansion plate 4 returns to the initial position under the action of the return spring 32, the limit block 28 is re-embedded into the limit groove 8 under the action of the second limit spring 29, the safety pillar 3 returns to the initial position under the action of the expansion plate 4, at this time, because the other end of the trigger rod 27 is in contact with the connecting block 26, the limit block 28 is re-embedded into the limit groove 8, and meanwhile, acting force is generated on one end of the trigger rod 27, so that the other end of the trigger rod 27 pushes the connecting block 26 to slide towards the direction of the stop block 17.

In some embodiments of the invention, when the vehicle hits the safety post 3, in particular, the slope of the second toothed cut 22 acts on the limit pin 24 before the impact, so that the limit pin 24 is stationary relative to the base 18. Because the elastic coefficient of the first limiting spring 25 is very large, the first limiting spring 25 deforms under a great impact force, when the impact occurs, the first limiting spring 25 is compressed, so that the limiting pin 24 contracts inwards along the inner wall of the second square groove 15, meanwhile, the limiting pin 24 slides relatively on the inclined plane of the second toothed notch 22, the second toothed notch 22 relieves the limitation on the rotating circular block 13 in the relative sliding process, the rotating circular block 13 rotates around the central axis of the base 18, the direct collision of the automobile and the safety post 3 is buffered, and the secondary damage of the impact of the automobile on the road post is avoided.

It should be noted that, before the car is impacted, the trigger pin 31 is stationary relative to the base 18 due to the slope of the first tooth notch 21 acting on the trigger pin 31. Under a large impact force, the first limit spring 25 deforms, so that the limit pin 24 can rotate relative to the second toothed notch 22, and the trigger pin 31 also performs relative displacement along the first toothed notch 21 under the impact force. Because the first tooth-shaped notch 21 has an inclination, and the first tooth-shaped notch 21 has a guide rail therein or the contact surface between the first tooth-shaped notch 21 and the trigger pin 31 has a smooth coating, when the trigger pin 31 is relatively displaced along the first tooth-shaped notch 21, after the automobile is impacted or the external force disappears, the trigger pin 31 will automatically return to the original position along the first tooth-shaped notch 21, and the large impact force makes the rotation amplitude of the limit pin 24 relative to the second tooth-shaped notch 22 large, and the elastic action generated by the first limit spring 25 is also large. Therefore, under the combined action of the trigger pin 31 and the first limit spring 25, the limit pin 24 rotating relative to the second toothed notch 22 automatically resets after the vehicle is impacted or after the external force disappears.

The technical solution of the embodiment of the present invention is described in detail above with reference to the accompanying drawings, in the embodiment of the present invention, by designing a road pillar, when a person who pushes the safety pillar 3 is not a manager of the road pillar, the safety pillar 3 is not pushed, only the manager of the road pillar acts on the manual lever 30, the manual lever 30 releases the limit of the limit block 28 on the limit groove 8 through the trigger lever 27, and the person pushes or pulls the safety pillar 3, so that the safety pillar 3 moves to the two sides of the road or the center of the road, thereby achieving the purpose of pushing the road pillar, at this time, the distance between the first road pillar 1 and the second road pillar 2 is correspondingly increased or decreased; when an automobile collides against the safety post 3, the safety post 3 swings around the central axis of the base 18 and automatically resets after the external force disappears, so that the collision between the safety post 3 and the automobile is buffered to the maximum extent, and the secondary damage of the road post and the automobile is reduced as much as possible.
