[0083] DETAILED DESCRIPTION: The billboard in the present invention is installed on the roof of a taxi. When the taxi is not driving, the blade 9 does not drive the first ring sleeve 16 to rotate, the first rotating shaft 48 does not rotate, the scroll spring 52 is in a natural state, and the triangular shift lever 53 is in contact with the slope 61 of a limit block 54. At this time, the advertisements on both sides of the triangular billboard 4 face the outside world. The second centrifugal wheel 21 is not rotating, and the friction wheel 25 frictionally fits with the rear cone end of the first cone-shaped friction wheel 29.

[0084] Setting: When the taxi is running, the blade 9 is blown by the wind to drive the first ring sleeve 16 to rotate clockwise; when the speed of the taxi reaches 30km / h, the first centrifugal wheel 18 just cannot be driven by the centrifugal block 33 The second rotating shaft 19 rotates.

[0085] When the taxi is traveling slowly, the blade 9 is blown b...

Abstract

The invention belongs to the technical field of advertising boards, and particularly relates to an advertising board for the car roof of a taxi. The advertising board comprises a base, a triangular advertising board body, an adjusting mechanism, a wind energy mechanism and the like, and the triangular advertising board body stops rotating and switching in the process of high-speed running of the taxi and intermittently rotates and switches in the process of low-speed running of the taxi so that the triangular advertising board body can effectively advertise three-side advertisings. According to the design that a friction wheel moves in the front cone end direction of a first cone type friction wheel, in the process of running of the taxi at different low speeds, the rotating switching speed of the triangular advertising board body can be kept unchanged as far as possible, and the advertising effect of the triangular advertising board body is improved. In addition, a pushed ring is pushed by rotating an adjusting ring, therefore the compression amount of a first spring is improved, more and more time is consumed in the process that a triangular stirring rod successively crosses limit blocks, the frequency of rotating and switching of the triangular advertising board body driven by a driving cylinder becomes low, and therefore the advertising effect of the triangular advertisingboard body under different circumstances is achieved.

Description

Technical field [0001] The invention belongs to the technical field of billboards, and particularly relates to a billboard used on the roof of a taxi. Background technique [0002] Currently, there is a billboard used on the roof of a taxi, which is a traditional fixed non-LED screen billboard. For traditional fixed non-LED screen billboards, its advertising needs to be advertised through the slogans that have been posted on the billboards. The advertising slogans can only advertise on both sides of the billboard at most. The advertising effect of the non-LED screen billboards is much worse than that of the fixed LED advertising screens on the market; but the traditional fixed non-LED screen billboards also have certain advantages: it will not be caused by the failure of the LED advertising screens. It cannot be advertised. In order to enable the traditional fixed non-LED screen billboard to more effectively expand the advertising effect, it is necessary to design a rotating tr...
