[0002] The demand for guardrails in scenarios such as construction, road maintenance, and outdoor activities is becoming increasingly diverse. Traditional guardrails are mostly fixed in size and shape, making it difficult to meet the flexible use requirements in different scenarios. The limitations of traditional guardrails are particularly evident in situations where quick splicing and adjustment are required. For example, in construction, the shape and size of the construction area may change with the progress of the project, and traditional guardrails are difficult to quickly adapt to such changes. In outdoor activities, such as large open-air gatherings and concerts, guardrails that can be quickly erected and disassembled are needed to divide areas and ensure the safety of people. In addition, traditional guardrails also have shortcomings in terms of mobility and safety, such as inconvenience in movement and lack of warning functions, making it difficult to meet the high safety and efficiency requirements of modern construction sites and outdoor activities. In view of this, there is an urgent need for a spliced plastic guardrail that is flexible in splicing, easy to move, safe and reliable, to solve the many problems of traditional guardrails in practical applications.

Two groups of the first elastic fixing ring 22 and the second elastic fixing ring 23 are respectively provided and symmetrically arranged on both sides of the connecting block 21 .
[0027] It should be noted that the bottom of the guardrail body 11 has mounting holes for the movable wheels 13. The movable wheels 13 are made of polyurethane, which has excellent wear resistance and shock absorption. The movable wheels 13 are installed in the mounting holes at the bottom of the guardrail body 11. By rolling the movable wheels 13, the guardrail can be easily moved, allowing it to quickly respond to on-site needs and facilitate splicing and protection in different locations.
[0028] Specifically, the splicing connecting rods 25 are arranged on the guardrail body 11, and the splicing connecting rods 25 are provided in two groups and are symmetrically arranged.
