Description

Technical Field

[0001] The utility model relates to the technical field of traffic guardrails, in particular to a traffic guardrail which is easy to assemble and disassemble. Background Art

[0002] Roadside guardrails are used to protect vehicles and their occupants from natural or man-made objects located beside the road. It is important to note that a vehicle striking a roadside guardrail may damage both the vehicle / occupants and the guardrail itself. The damage caused by a collision with a guardrail is usually not as severe as a collision with components located behind the guardrail. Therefore, roadside guardrails represent a compromise between these two considerations. In addition to protecting vehicles, roadside guardrails are also used to shield pedestrians and maintenance / construction workers. In its most basic form, roadside guardrails are designed to prevent vehicles leaving the roadway from striking fixed objects. The guardrail first stops an accident vehicle and then redirects it.

[0003] When installing, traffic guardrails are mostly welded into a whole. When the traffic guardrail needs to be disassembled, it is easy to cause the traffic guardrail to be damaged, affecting the secondary use of the traffic guardrail. Or it is fixed by bolts. The bolts are easily damaged after long-term use, resulting in a decrease in the locking ability of the bolts, affecting the firmness of the traffic guardrail. Therefore, we propose a traffic guardrail that is easy to disassemble and assemble. Utility Model Content
