[0002] Road traffic refers to the flow and stay of vehicles and pedestrians on roads, which includes people, vehicles (any vehicle) passing on the roads, as well as related traffic activities and phenomena. In this definition, "road" refers to highways, urban roads, and places that are under the jurisdiction of units but allow social motor vehicles to pass, including squares, public parking lots and other places for public passage. And "vehicle" includes motor vehicles and non-motor vehicles. Among them, a motor vehicle is a wheeled vehicle driven or towed by a power device and used for carrying people or transporting goods and performing special engineering operations on the road; a non-motor vehicle is a vehicle driven by human power or animal power and used for traveling on the road, as well as some vehicles such as electric bicycles that are driven by a power device but whose maximum designed speed, unladen mass, and external dimensions meet relevant standards.

[0003] Road traffic fences are an important part of road traffic safety facilities, mainly used for separating roads, protecting the safety of pedestrians and vehicles, maintaining traffic order, etc. Road traffic fences are exposed outdoors all year round and need to withstand the erosion of natural environments such as wind, sun, and rain. These environmental factors will cause the metal material on the surface of the fence to gradually oxidize and corrode, thereby reducing the service life and safety of the fence. It is necessary to paint the surface of the fence for protection.

[0004] Existing painting devices cannot adjust the distance between the spray nozzle and the fence according to different fence thicknesses, resulting in the problem that if the painting distance is too close, the paint may flow or accumulate, forming an uneven coating; if the distance is too far, the paint mist may disperse, resulting in a thin and uneven coating, with pitting or missed spraying. Content of the Utility Model

[0005] Aiming at the above problems, the purpose of the utility model is to provide a painting device for road traffic fences, which solves the problem that existing painting devices cannot adjust the distance between the spray nozzle and the fence according to different fence thicknesses, resulting in the problem that if the painting distance is too close, the paint may flow or accumulate, forming an uneven coating; if the distance is too far, the paint mist may disperse, resulting in a thin and uneven coating, with pitting or missed spraying.
