Embodiment
The present invention is a kind of lifting multimedia presentation device, lifts multimedia presentation device, including more piece monomer 2, monomer 2Lateral surface is rectangle and is provided with display screen 3, is hinged and connected composition etc. between remaining monomer 2 in addition to being not attached between one group of adjacent monomer 2Regulation 2 angles of adjacent monomer of hydraulic cylinder 4, two are additionally provided between the polygon-shaped handset 1 in side, the adjacent monomer 2 being hinged and connectedA fixation in disjunct monomer 2, monomer 2 is supported into the display of setting under the driving of hydraulic cylinder 4 by equilateral polygon shapeShield 3 towards unidirectional multimedia presentation device handset 1.
The monomer 2 is trapezoid cylinder 201, and the display screen 3 is arranged on the bottom surface 202 of trapezoid cylinder 201, trapezoidalThe upper bottom surface 203 of cylinder 201 inwardly, is faced outwardly, the prism 204 between adjacent trapezoidal cylinder 201 is in contact where display screen 3.The articulated position being connected between the monomer 2 is on the rib between the prism 204 and bottom surface 202 of trapezoid cylinder 201, the hydraulic pressureThe fixing end and external part of cylinder 4 are separately positioned on two trapezoid cylinders 201 being hinged and connected.Fixed monomer bottom is provided with supportIntegral device support is left ground by frame.Display screen 3 on the monomer 2 includes the internal layer display screen 301 and folding for being close to monomer 2The outer layer display screen 302 of overlapping state, outer layer display screen 302 is in same plane after deploying with internal layer display screen 301.
The handset 1 is spaced side by side, and monomer 2 is erected vertically in handset 1, on monomer 2 outer layer display screen 302 deploy after with it is interiorThe multimedia show plane that the layer composition of display screen 301 is erect.Integral device support is left ground by middle frame 5 provided with support frame 7.
Embodiment 1, includes the horizontally disposed middle frame 5 of central shaft of column, and middle frame 5 is arranged on polygon-shaped sonIn the middle of machine 1, the upper bottom surface 203 of trapezoid cylinder 201 is contacted with middle frame 5 in handset 1, and the polygonized structure in monomer besieged city is around centreFrame one week.
Fixed trapezoid cylinder 201 is fixed on middle frame 5.The fixing end of hydraulic cylinder 4 is fixed on the oblique side of trapezoid cylinder 201On edge rib between face 204 and upper bottom surface 203, the external part of hydraulic cylinder 4 connects the trapezoidal column adjacent with above-mentioned trapezoid cylinder 201The middle part of body 201.
Operation principle：
Middle frame is static in place, and the foot that trapezoid cylinder is in middle frame, and the trapezoidal column are fixed in the positionThe bottom surface of body is in horizontality.Hydraulic cylinder structure starts on adjacent with fixed trapezoid cylinder but disjunct trapezoid cylinderEffect, the external part of hydraulic cylinder is stretched out, and the trapezoid cylinder is promoted and rotated around articulated position on suitable angle, the trapezoid cylinderDisplay screen is in same plane on the coupled trapezoid cylinder of display screen, completes the first step of more piece Monolithic driver.
Start remaining hydraulic cylinder successively, the display screen on all trapezoid cylinders is driven in plumbness, list is completedThe arrangement of body handset.
Handset 1 is spaced side by side, and outer layer display screen 302 constitutes the multimedia show erect after deploying with internal layer display screen 301Plane.Integral device support is left ground by middle frame 5 provided with support frame 7.
Embodiment 2, the edge rib of upper bottom surface 203 of adjacent trapezoid cylinder 201 is hinged with two support bars 6 respectively, two supportsExternal part top of the bar 6 in end simultaneously with hydraulic cylinder 4 is hinged and connected, and the fixing end of hydraulic cylinder 4, which is hinged, is arranged on corresponding phaseArticulated position between adjacent trapezoid cylinder 201.
In a quiescent state, hydraulic cylinder external part stretches out, between the support bar on adjacent trapezoidal cylinder 201 in angle mostSmall state, the prism of adjacent trapezoidal cylinder 201 is in close contact, and now handset is polygon-shaped.The external part of hydraulic cylinder is openedBegin retraction, angle between the support bar on adjacent trapezoidal cylinder 201 is strutted, on adjacent trapezoidal cylinder 201 between prism separation.The external part of hydraulic cylinder is retracted to the length of requirement, and now the display screen of adjacent trapezoidal cylinder 201 is in same plane state, mostEventually except securing trapezoid cylinder 201 and adjacent several, display screen is in hydraulic pressure after vertical state on remaining trapezoid cylinder 201Cylinder is stopped and pinned.
Now the handset display screen of state is towards same direction, and deploys its outer layer display screen, and handset 1 is spaced side by side, outsideLayer display screen 302 constitutes the multimedia show plane erect after deploying with internal layer display screen 301.
Integral device of the present invention can retract into the round shape of centre of gravity height, highly be reached after expansion, can piece together big flatFace multimedia equipment, for some large-scale activities, it arranges that speed is fast, reduces setting up cost；Come as advertising equipmentSay, moulding is changeable, pedestrian can be attracted to watch, improve the dispensing effect of advertisement.
The present apparatus is compared to the advertising equipment of splicing, and speed that it is arranged is fast, saves the time.
