[0083] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The billboard in the present invention is installed on the roof of a taxi. When the taxi is not running, 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, the triangular lever 53 is in contact with the inclined surface 61 of a limit block 54, At this time, the advertisements on both sides of the triangular billboard 4 face the outside world for publicity. The second centrifugal wheel 21 does not rotate, and the friction wheel 25 is in frictional fit with the rear conical end of the first cone friction wheel 29 .

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

Abstract

The invention belongs to the technical field of advertising boards, in particular to a billboard used on a taxi roof. The billboard comprises a base, a triangular billboard body, an adjusting mechanism, a wind energy mechanism and the like, wherein the triangular billboard body can stop rotating and switching when the taxi runs at a high speed and intermittently rotate and switch when the taxi runs at a low speed, so that the triangular billboard body can effectively propagandize three advertisements; due to the design that a friction wheel moves towards the front conical end of a first conical friction wheel, when the taxi runs at different low speeds, the rotating and switching speed of the triangular billboard body can be kept unchanged as much as possible, and the advertising effect ofthe triangular billboard body is further improved; moreover, a pushed ring is pushed by rotating an adjusting ring, so that the compression amount of a first spring is increased, the time that a triangular deflector rod sequentially passes through limiting blocks is longer and longer, the frequency that a driving cylinder drives the triangular billboard body to rotate and switch is decreased, andthe advertising effect of the triangular advertising board under different conditions 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] At present, 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 promoted through the slogans that have been posted on the billboards, and its advertising slogans can only promote both sides of the billboard at most. The advertising effect of the non-LED screen billboard is much worse than that of the fixed LED advertising screen on the market; but the traditional fixed non-LED screen billboard also has certain advantages: it will not be caused by the failure of the LED advertising screen. rather than advertising. In order to more effectively expand the advertising effect on the traditional fixed non-LED screen billboard, it is necessary to design a rotating traditional...
