Description
Technical Field
[0001] The utility model relates to the technical field of road signs, in particular to an adjustable luminous road sign. Background Art
[0002] Luminous road signs are signs with luminous functions set on the road, usually used to improve the recognition and attention of drivers to road signs at night or in low visibility conditions. The road traffic environment will change due to factors such as weather, time and traffic conditions. Adjustable road signs can adjust the brightness, color or display content according to these changes to ensure that clear and visible road instructions can be provided under various conditions, so an adjustable luminous road sign is needed.
[0003] An existing adjustable luminous road sign has an adjustment slot, a roller and a rotating shaft when in use, so that the road sign has a storage function. When encountering bad weather and other conditions, there is almost no traffic on the road. At this time, the force exerted by other factors such as wind on the road sign is relatively large, which can easily cause collapse. By folding the warning block by storage, the effect of external force on the road sign can be effectively reduced, thereby greatly improving the service life of the road sign.
[0004] However, when using this method, the height of the sign cannot be adjusted. If the height of the luminous road sign cannot be adjusted, the sign will be blocked or blocked by other objects, reducing the visibility of the sign, especially on highways or complex roads. Drivers may not be able to see the sign clearly, which may lead to incorrect driving direction choices or traffic accidents. Utility Model Content
