Description

Technical Field

[0001] The utility model relates to the field of road markings, in particular to a portable road marking device. Background Art

[0002] Road marking is a crucial task in road construction and maintenance. Road markings not only indicate driving directions and lane demarcations, but also serve as warnings and traffic guides, making them crucial for ensuring traffic safety. Traditional road marking methods typically rely on manual application with handheld spray nozzles. This method is inefficient and difficult to maintain consistent marking width, compromising both accuracy and aesthetics.

[0003] Technological advancements have led to the emergence of mechanized and automated road marking equipment. While these devices have improved marking efficiency to a certain extent, they still have some shortcomings. For example, while some equipment can automatically apply markings, the width of the markings is typically fixed, making it difficult to adjust according to actual needs. To achieve different widths, it is often necessary to replace nozzles of different sizes, which not only increases operational complexity but also increases costs.

[0004] Furthermore, most existing road marking equipment is bulky and inconvenient to transport and carry. This significantly limits their flexibility, especially when marking on narrow or complex roads. Therefore, there is an urgent need for a road marking device that can flexibly adjust the marking width and is easy to carry and transport. Utility Model Content
