Problems solved by technology

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 exceeded, a collapse accident
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. The card seat is connected to the base through the rotating shaft, and the main shaft is connected to the stepping motor; the frame is equipped with a wind speed sensor, and a leaf angle control mechanism connected to the main shaft is installed on one side of the frame, and the wind speed sensor is connected to the input end of the controller. , the leaf angle control mechanism and the stepper motor are connected to the output end of the controller, which controls the leaf rotation through the motor to release the wind energy. Its structure is complex, the production cost is high, and the maintenance cost is high. It is not suitable for non-energized Billboard, in addition, the application publication number is a wind-resistant billboard disclosed by CN 101976539A, which includes a frame and advertising panels arranged on the front and back of the frame. The frame is equipped with a convex part that blocks the rotation of the leaf, and the rotating structure is easy to swing in the case of a breeze, which interferes with the display content of the billboard. At the same time, the spring is easy to deform and loose, and the service life is short

Abstract

The invention discloses a wind-resistant advertising board comprising a frame and a main board. The main board is composed of a plurality of blades arranged side by side. The blades are hinged to the frame. The frame is provided with a steering driving assembly for inducing wind power to drive the blades to rotate. The steering driving assembly comprises a plurality of gears, racks and a sliding block. The gears are fixed to the plurality of blades. The sliding block extends and has a first windward piece. A windward surface of the first windward piece is parallel to the main board. The sliding block is driven by wind to slide in a direction vertical to the arrangement direction of the blades. The racks are intermeshed with the plurality of gears. The racks are hinged to the sliding block via draw bars. When the sliding block is moving in a first sliding chute back and forth, the sliding block drives the racks to move in the arrangement direction of the blades. The first sliding chute is provided with elastic components to keep the sliding block to reset. The advertising board can be normally used under the normal or breeze condition and is capable of dispelling wind when subject to large head-on wind, and wind resistance of the advertising board is improved.

Description

technical field [0001] The invention relates to the field of billboards, in particular to a wind-resistant billboard. Background technique [0002] 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. Increasin...
