Description

Technical Field

[0001] The utility model belongs to the field of guardrails, and in particular relates to an anti-collision guardrail which is easy to disassemble and assemble. Background Art

[0002] Guardrails are traffic facilities used on both sides of the road. Most common guardrails are detachable structures, but some guardrails are difficult to disassemble and assemble, which will lead to the following problems.

[0003] Difficult maintenance: If the guardrail is difficult to disassemble and install, it will be more difficult to perform routine maintenance and repair work on the guardrail. For example, if a section of the guardrail needs to be replaced or repaired, disassembling the entire guardrail may be very time-consuming and labor-intensive.

[0004] Safety hazards: Guardrails are used to protect people in some situations. If the guardrails are difficult to disassemble and assemble, it may cause difficulties when people need to be evacuated quickly in an emergency. In addition, if the guardrails cannot be fixed firmly, the risk of accidents will increase.

[0005] Impact on use: The inconvenience of disassembling and assembling the guardrail may affect its use. For example, if the guardrail cannot be disassembled and installed securely, it may cause the guardrail to shake or tilt during use, affecting its protective function.

[0006] Increased costs: The inconvenience of guardrail removal and installation may increase the cost of maintaining and replacing the guardrail. If specialized tools or manpower are required to remove the entire guardrail, the cost of maintaining the guardrail will increase.
