Anti-strong-wind advertising board for municipal roads

Abstract

The invention discloses an anti-strong-wind advertising board for municipal roads. The advertising board comprises a fixed frame with openings in two side walls; the side walls of the fixed frame areprovided with display grooves; the side walls of the display grooves are rotationally connected with a plurality of advertising boards through cross rods; the multiple advertising boards are of a louver structure; two grooves are symmetrically formed in the side walls of the fixed frame; the side walls of the two grooves are in sliding connection with racks; the lower ends of the racks are elastically connected with the inner bottoms of the grooves through first springs; and driving devices for driving the racks to move are mounted on the fixed frame. By arranging fan blades fixedly connectedwith rotating shafts, when strong wind blows towards the advertising boards, the fan blades drive the rotating shafts to rotate rapidly, so that magnetic sliding blocks slide towards the side walls ofannular grooves under the action of centrifugal force generated by rapid rotation of the rotating shafts, magnetic sliding plugs are pulled to slide down, the advertising boards are opened, the strong wind penetrates through gaps between the advertising boards, and the advertising boards are prevented from being damaged under the action of the strong wind.

Description

technical field [0001] The invention relates to the technical field of billboards, in particular to a municipal road anti-strong wind billboard. Background technique [0002] Billboards are tools used to convey information, especially outdoor billboards. Outdoor billboards can display the image and brand of a company in a fixed location for a long time, so it can effectively improve the popularity of the company and the brand. Because the outdoors are relatively empty, The wind is strong, so when the billboard encounters strong winds, the strong wind can easily damage the billboard, resulting in increased display costs for the company, and the billboard is set up outdoors, and the staff will not frequently check the display of the billboard , After the billboard is damaged, it cannot be processed in time, and the damaged billboard will have an impact on the promotion of corporate and brand awareness. [0003] The existing outdoor billboards resistant to strong winds are des...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned patent solves the problem that billboards are easily damaged when encountering strong winds, when a constant breeze is generated outdoors, the driving device will rotate slowly under the drive of the breeze, thereby slowly winding the cable and eventually pulling the billboard Entering the base, this makes the billboard shrink even under non-strong wind conditions, which is not conducive to the display of the billboard, and the billboard does not shrink rapidly during the shrinking process, which makes there still be some advertisements when the strong wind blows The billboard is exposed to the outside and is exposed to strong winds, which will cause damage to the billboard in the long run
