When the second moving plate... The anti-collision capability increases after the movable anti-collision plate makes contact. The third and fourth racks move along the same trajectory as the first and second racks. When the second and fourth racks move forward, the first and second helical teeth drive the reinforcing rods forward to contact the second movable plate, thus reinforcing it. After the collision accident is handled, the lead screw at the adjuster drives the fixed rod to move downward, causing the sleeve and lower cam to move downward. After the lower cam connects with the upper cam, the cylinder rotates, causing the first and third racks to move forward and reset the movable anti-collision plate, allowing the anti-collision device to be reused. The rotating shaft and warning sign can rotate under the action of vehicle speed to remind the driver. The reinforcing rods and sandbags inside the second movable plate improve the anti-collision capability. Attached Figure Description

A third rack 20 is provided on the base plate 9. The third rack 20 is symmetrically arranged with the first rack 12 along the center line of the base plate 9. The third rack 20 is connected to the first connecting rod 8. The first connecting rod 8 has two rods. The third rack 20 meshes with the second gear 21. The other end of the second gear 21 meshes with the fourth rack 19. The fourth rack 19 is symmetrically arranged with the second rack 14 along the center line of the base plate 9. The fourth rack 19 is connected to the second connecting rod 15. A sliding groove 17 is provided at the center line of the base plate 9. The reinforcing rod 16 is slidably connected to the sliding groove 17. Tooth grooves 18 are provided on both sides of the reinforcing rod 16. The second rack 14 has an integrally formed first helical tooth 23 on the side near the reinforcing rod 16. The fourth rack 19 is near the... One side of the reinforcing rod 16 is provided with an integrally formed second helical tooth 22. The first helical tooth 23 and the second helical tooth 22 are inclined towards the second moving plate 10, and the first helical tooth 23 and the second helical tooth 22 are connected to the tooth groove 18. The adjuster 2 includes a lower cam 25, a sleeve 26, a cylinder 33, a displacement spring 27, a limiting block 28, and a vertical rod 29. The vertical rod 29 is installed on the housing 1 by screws.

[0018] The working principle of this invention is as follows: Multiple housings 1 are arranged according to the road linearity. After the arrangement is completed, the lower cam 25 and the upper cam 24 at the adjuster 2 are separated. When the vehicle loses control and collides with the anti-collision moving plate 4, the roller 6 at the front end of the anti-collision moving plate 4 can rotate, which not only protects the vehicle but also dissipates part of the collision force. Under the action of the collision force, the anti-collision moving plate 4 moves backward. The backward movement of the anti-collision moving plate 4 causes the first connecting rod 8 to move backward. The backward movement of the first rack 12 on the first connecting rod 8 causes the first gear 13 to rotate. The rotation of the first gear 13 causes the second rack 14 to move forward. The forward movement of the second rack 14 causes the second connecting rod 15 to move forward. The second moving plate 10 moves towards the anti-collision moving plate 4 under the action of the second connecting rod 15. When the second moving plate 10 contacts the anti-collision moving plate 4... The rear anti-collision capability is increased. The third rack 20 and the fourth rack 19 have the same movement trajectory as the first rack 12 and the second rack 14. When the second rack 14 and the fourth rack 19 move forward, the first helical tooth 23 on the second rack 14 and the second helical tooth 22 on the fourth rack 19 match the tooth groove 18, thereby driving the reinforcing rod 16 to move forward until it contacts the second moving plate 10, thus reinforcing the second moving plate 10. After the collision accident is handled, the screw 32 at the adjuster 2 is rotated to move it down. The screw 32 drives the fixed rod 30 to move down, thereby moving the sleeve 26 and the lower cam 25 down. After the lower cam 25 is connected to the upper cam 24, the cylinder 33 is rotated to move the first rack 12 and the third rack 20 forward, thereby resetting the anti-collision moving plate 4, which allows the anti-collision device to be reused.
