Advertising box capable of maintaining advertising cloth to always move at constant speed according to wind power

Abstract

The invention relates to the technical field of advertising media, and provides an advertising box capable of maintaining advertising cloth to always move at a constant speed according to wind power.Theadvertising box comprises a box body, fan blades are movably connected to the outer wall of the box body, magnetic poles are movably connected to the outer walls of the fan blades, and rotating blocks are movably connected to the outer walls of the fan blades. According to the advertising box capable of maintaining the advertising cloth to always move at the constant speed according to the windpower, the advertising box is arranged outdoors, the fan blades rotate and drive the coils to cut magnetic poles, generated magnetic force is led to the electromagnets, the electromagnets attract therod sleeves to change the positions of the rod sleeves, and the larger the wind power is, the larger the magnetic force of the electromagnets is and the larger the moving distance of the rod sleevesis; at the moment, the proportion of the rod sleeves, the lever and the rack plate changes, and the rod sleeve is far away from the rack plate to increase the distance between the rod sleeve and the fulcrum; and although the swing frequency of the rod sleeve is high, the moving distance of the rack plate is reduced, the angle of the rack plate driving the outer rotating wheel to rotate is reduced,and the proportion of the rod is adjusted through wind power changes to maintain uniform-speed playing of dynamic advertisements.

Description

technical field [0001] The invention relates to the technical field of advertising media, in particular to an advertising box that keeps advertising cloth moving at a constant speed according to wind force. Background technique [0002] Advertising media is a means of transmitting certain information to the public. Advertising media needs carriers for advertising. Common advertising media carriers include advertising boxes, billboards and TV. With the development of the times, business continues to develop. No matter how good the product is, it needs to be widely advertised to attract more customers. The smell of wine is also afraid of deep alleys.

Problems solved by technology

[0003] In the prior art, the advertisement box puts advertisements inside it, which is difficult to attract people's attention in the same way, and some dynamic advertisements use electricity to drive the advertisement cloth to rotate, which consumes power, and the advertisement box is placed outdoors for a long time. Poor environment will affect the display of advertisements. It is difficult for people to pay attention to the fact that such advertisements cannot play an effective publicity role, and the wind force directly affects the rotation speed of dynamic advertisements. Too fast directly affects the viewing of advertisements. Advertising boxes that always move at a constant speed came into being
