[0002] Display screen refers to information display terminal equipment that can display numbers, text, graphics and images. Traffic display screens are installed on the suspension board of highways. They are mainly used for broadcasting traffic information and play an important role in the transmission of traffic information. The overall structure of the display screen is relatively fragile and can be easily damaged by bad weather, causing unnecessary losses. Highways are open areas, and traffic display screens are more likely to be damaged by bad weather. Bad weather refers to heavy snow, freezing, low temperature, strong wind (sandstorm), hail, heavy rain and continuous rain. Traffic display screens sometimes encounter bad weather;

[0003] However, existing traffic display screens lack protective devices and are easily damaged in severe weather, which increases maintenance costs and reduces display effects and timely transmission of displayed information, affecting normal use. Utility Model Content
