However, for traditional fixed non-LED screen billboards, its advertising needs to be promoted through the slogans that have been posted on the billboards. The advertising effect of fixed non-LED screen billboards is much worse than that of fixed LED advertising screens; in order to expand the advertising effect more effectively on traditional fixed non-LED screen billboards, it is necessary to Design a rotating traditional fixed non-LED screen billboard to increase the number of slogans on the traditional fixed non-LED screen billboard and switch without interruption, so as to make up for the problem of poor advertising effect

specific Embodiment approach

[0057] The specific embodiment: the billboard among the present invention is installed on the roof of the taxi. When the taxi is not running, the blade 10 does not drive the sleeve 13 to rotate, the first rotating shaft 14 does not rotate, the first spring 28 is in a natural state, and the ring sleeve 15 is nested on the outer circular surfaces of the first rotating shaft 14 and the second rotating shaft 16 Above; one ends of the two guide keys 26 are respectively located in the two first key grooves 25 , and the other ends are respectively located in the two symmetrically distributed second key grooves 27 . The worm end on the fourth rotating shaft 71 does not rotate, the turbine 72 is locked, and then the rectangular billboard 4 is limited.

[0058] Setting: when the taxi is running, the blade 10 is blown by the wind to drive the sleeve 13 to rotate; when the taxi’s driving speed reaches 30km / h, the ring sleeve 15 and the guide key 26 move axially toward the sleeve 13 so tha...

Abstract

The invention belongs to the technical field of advertising boards, and particularly relates to a rotatable advertising board of a taxi roof. The rotatable advertising board comprises a base, a rectangular advertising board body, a wind energy mechanism and an adjusting mechanism, wherein the rectangular advertising board body can be stopped rotatably switching when a taxi is driven at high speed,and can intermittently and rotatably switch when the taxi is driven at low speed, and therefore four-surface advertisements can be effectively publicized through the rectangular advertising board body. Through a design that a fourth gear is driven by engagement periodicity of the arc section of a third gear to rotate, a worm wheel can intermittently rotate accordingly, and thus the advertising surfaces can be intermittently and rotatably switched through the rectangular advertising board body; as the rectangular advertising board body intermittently and rotatably switches, the time requirement when advertising language of one surface of the rectangular advertising board body is externally publicized is met. The worm wheel is in thread fit with the worm end on a fourth rotating shaft, andthrough the traditional self-locking function of the worm wheel and the worm, it is guaranteed that the rectangular advertising board body can be limited after rotating 90 degrees, and the possibilitythat the rectangular advertising board body freely and rotatably switches under the external influence is avoided.

Description

technical field [0001] The invention belongs to the technical field of billboards, in particular to a rotating billboard on the roof of a taxi.
