It is lifted up.Hoisting mechanism can be hydraulic cylinder, be also possible to screw mechanism, and the promotion of display screen is realized by hoisting mechanism,
It can be improved the propagation distance of picture in display screen, and the lift lever of this multi-stag can also be well adapted for the liter of display screen
Drop.
Further, lift lever is connected on turntable, and turntable is rotatably arranged on pedestal, and driving mechanism and turntable are driven
Couple and turntable is made to drive fixed screen and overturning screen that change in location occurs on pedestal by lift lever.Turntable can be in pedestal
On rotate, and position of the display screen on pedestal is changed, can be realized the propagation of multi-angle picture, improve wide
Accuse the coverage area that content is propagated.
Further, integrally formed with several driving cogs on the outer peripheral surface of turntable, motor power output shaft, which is equipped with, to be driven
Moving gear, driving gear are meshed with driving cog.This driving mechanism structure is simple, is easy to implement job control, convenient for display
Shield the rotation of 360 degree of the realization on pedestal.
Therefore, the utility model has the beneficial effects that the display screen on this loudspeaker van is by fixed screen and overturning screen structure
At overturning screen can have certain position change relative to fixed screen, and the textures multiplicity of display screen, structure itself can produce
Raw positive visual effect.In use, the multiplicity propagated by the change of display screen structure, Lai Shixian advertisement picture
Property, the means of advertising are enriched, can effectively meet different occasions to the setting demand of media.Overturning screen passes through pairs of
The stretching item of setting and fixed screen are hinged together, this can be well adapted for overturning screen and cut between two operating positions
It changes.It lifts mechanism driving with cylinder formula top by the driving item being arranged in pairs to couple, structure is simple, convenient for overturning screen in two working positions
Switching between setting.
