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 billboards, in particular to a rotating billboard on the roof of a taxi, which includes a base, a rectangular billboard, a wind energy mechanism, and an adjustment mechanism, wherein the rectangular billboard can stop rotating when the taxi is running at high speed Switching, and intermittently rotating and switching when the taxi is driving at low speed, so that the rectangular billboard can effectively promote the four-sided advertisement. The meshing of the arc segment on the third gear periodically drives the fourth gear to rotate, so that the turbine can rotate intermittently, so that the rectangular billboard can rotate intermittently to switch the advertising surface; the rectangular billboard rotates intermittently Switching to meet the time for advertising on one side of the rectangular billboard. The threading of the turbine and the end of the worm on the fourth rotating shaft uses the traditional self-locking function of the turbine and the worm to ensure that the rectangular billboard can be limited after rotating 90 degrees, and avoids the rectangular billboard being affected by the outside world. The possibility of free spin switching.

Description
