[0002] The main structural parts of the guardrail end are composed of the end structure, corrugated plate, column, guide rail, anti-blocking block, front fixed end and rear fixed end. The existing anti-collision energy-absorbing end can absorb the impact energy through the corrugated structural plate in the process of extrusion, straightening and curling. The buffer slot can connect the sliding frame and can also achieve the effect of energy unloading during the vehicle collision. The buffer slot finally completes the separation of the sliding frame and the guardrail plate body, but the end is damaged after the impact. The guardrail needs to be completely disassembled, and there is no guardrail to distinguish the road before replacing the new guardrail and the end, which is not conducive to the passage of vehicles and pedestrians on the road without guardrails. After searching, it was found that the technical solution provided by the utility model with application number also has the above-mentioned problems. Utility Model Content

[0024] Working principle: During installation, the second corrugated plate 9 is overlapped with the first fixing hole 11 of the first corrugated plate 8 and connected to the first column 10 with the fixing screw 12. The second column 13 connects the end arc plate 6 and the first corrugated plate 8. When hit by a vehicle, the end arc plate 6 can absorb a large amount of impact force and transmit it to the first corrugated plate 8. The length of the first fixing hole 11 is five times the diameter of the fixing screw 12. The impact force causes the fixing screw 12 to slide in the first fixing hole 11, thereby preventing the second corrugated plate 9 from being damaged. Since the end connecting plate 7 is connected to the first corrugated plate 8 by a connecting ring 14, if the end is damaged, only the damaged end arc plate 6 and the first corrugated plate 8 need to be moved. There are more first fixing holes on the second corrugated plate 9 that can be used to connect with the first column 10 and remain in place to continue to play a road guiding role.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
