technical field

The invention relates to the field of billboards, in particular to a wind-resistant billboard.

Background technique

Billboards are the most common advertising method for people in places with a lot of people or traffic. The accidental damage of outdoor billboards is a major safety hazard that directly threatens the lives and property safety of the masses. In the event of accidental damage to billboards, the most prominent form of damage is insufficient wind resistance, or a sudden encounter with rare local strong winds, causing the billboard to fall or even collapse as a whole. Existing billboards are getting bigger and bigger, and the area of billboards exposed to wind increases. In sudden strong winds, general billboards cannot release the strong instantaneous or short-term force caused by strong winds. When this force exceeds the billboard When the strength of the card structure is insufficient, a collapse accident will occur. Increasing the strength of billboards and their brackets is a direct way to solve the problem, but there is a limit to increasing the strength, which will not only consume a lot of steel, but also increase the production cost. In the prior art, there is a rotating leaf-type wind-resistant outdoor billboard disclosed by the authorized announcement number CN 205541781U, which includes a leaf, which is connected to the frame through a spindle, and the frame is fixed on the rotating deck.
