[0020] In the following description, embodiments of the multi-stage buffer type anti-collision highway construction warning sign of this utility model will be described with reference to the accompanying drawings.

[0021] Example 1: Figure 1-4This invention illustrates a multi-level buffer anti-collision highway construction warning sign according to an embodiment of the present invention. It includes a base plate 1. The top of the base plate 1 has a rectangular groove 2 and a T-shaped groove 3. A cylindrical cavity 4 is formed inside the base plate 1. A T-shaped slider 5 is slidably connected to the inner wall of the T-shaped groove 3. Two symmetrically arranged vertical lugs 6 are fixedly connected to the top of the T-shaped slider 5. A rotating shaft 7 is rotatably connected to the inner wall of the lugs 6. A circular vertical plate 8 is welded to the surface of the rotating shaft 7. A steel upright 9 is positioned above the circular vertical plate 8. Rectangular plates 10 are fixedly connected to the bottom end of the steel upright 9 and the surface of the rotating shaft 7. The two rectangular plates 10 are connected together. Equipped with bolts 11, the steel upright 9 and the rotating shaft 7 can be disassembled and assembled through the cooperation of the rectangular plate 10 and the bolts 11. The steel upright 9 can be disassembled and replaced when it is damaged, which further improves the economy. The surface of the lug 6 is bolted with bolt rods 12. The end of the bolt rods 12 passes through the lug 6 and abuts against the circular vertical plate 8. The top of the steel upright 9 is fixedly connected with a warning sign block 13. The front and rear sides of the T-shaped slider 5 are fixedly connected with the inner wall of the cylindrical cavity 4 with buffer pull ropes 15 and springs 16, respectively. The rear side of the inner cavity of the rectangular groove 2 and the T-shaped slider 5 are fixedly connected with a rubber pad 17.

[0022] Example 2: Figure 1-4 This invention illustrates a multi-stage buffer anti-collision highway construction warning sign according to an embodiment of the present invention. It includes a base plate 1. The top of the base plate 1 has a rectangular groove 2 and a T-shaped groove 3. A cylindrical cavity 4 is formed inside the base plate 1. A T-shaped slider 5 is slidably connected to the inner wall of the T-shaped groove 3. Two symmetrically arranged vertical lugs 6 are fixedly connected to the top of the T-shaped slider 5. A rotating shaft 7 is rotatably connected to the inner wall of the vertical lugs 6. A circular vertical plate 8 is welded to the surface of the rotating shaft 7. A steel upright 9 is positioned above the circular vertical plate 8. Bolts are connected to the surface of the vertical lugs 6. The top of the bolt rod 12 and the steel pole 9 is fixedly connected to a warning sign block 13. The surface of the base plate 1 is fixedly connected to a side hole block 14. The side hole block 14 facilitates the fixing of the base plate 1 buried in the ground with expansion bolts, which improves the stability of the base plate 1 when it is embedded in the ground. The front and rear sides of the T-shaped slider 5 are fixedly connected to the inner wall of the cylindrical cavity 4 with a buffer pull rope 15 and a spring 16, respectively. The spring 16 is in a deformed and compressed state. The rear side of the inner cavity of the rectangular groove 2 and the T-shaped slider 5 are fixedly connected to a rubber pad 17.

[0023] Working principle: When this utility model is in use, the user can use the rubber pad 17 to buffer the T-shaped slider 5 when the steel pole 9 is impacted, allowing the T-shaped slider 5 to move backward. This allows the T-shaped slider 5 to enter the inner cavity of the rectangular groove 2 through the T-shaped groove 3. At the same time, the buffer rope 15 and the spring 16 work together to buffer the force on the T-shaped slider 5. Subsequently, under the impact, the steel pole 9 and the T-shaped slider 5 move backward to abut against the rear side of the inner cavity of the rectangular groove 2. At this time, the steel pole 9 drives the rotating shaft 7 to rotate, and the bolt rod 12 further buffers the impact by squeezing and rubbing against the circular vertical plate 8. This achieves the goal of fixing the warning sign to the ground and buffering the impact when it is hit by a collision, thereby reducing the damage to the warning sign when a vehicle crashes.

[0024] In summary, this multi-stage buffered anti-collision highway construction warning sign uses the combined use of the buffer rope 15 and spring 16 to buffer the force on the T-shaped slider 5. Subsequently, the steel pole 9 and the T-shaped slider 5 move backward under the impact. At this time, the steel pole 9 drives the rotating shaft 7 to rotate. At the same time, the bolt rod 12 further buffers the impact by squeezing and rubbing against the circular vertical plate 8. This achieves the purpose of being fixedly installed on the ground and buffering the impact when it is hit by a collision, thereby reducing the damage to the warning sign when a vehicle hits it.
