Be that the utility model adjoint is described in further detail below:

Referring to Fig. 1, on housing 21 bases, fixedly speed reduction unit 3, and speed reduction unit 3 output terminals are connected output terminal, the output terminal assembling luffing cam 4 and the synchronized positioning cam 6 arranged side by side of speed reduction unit 3, cam 4 and the 6 synchronous slowly rotations of motor 1 with belt through belt pulley 2.Assemble the

lever

5 and 7 of synchronization action on the base of housing 21 with bearing pin, wherein lever 5 one ends cooperate with luffing cam 4, lever 7 one ends cooperate with positioning cam 6, the other end assembles pull bar 16 with bearing pin, the locating sleeve 17 of assembling taper type on the movable up and down pull bar 16, housing 21 1 sides are assembled rotating fixed head 18 and are slidingly matched with locating sleeve 17 conical surfaces, and the draw-in groove of location-plate 18 opposite sides is done the location with rotating former 14 and cooperated.Referring to Fig. 2, the left end of lever 5 and synchronising (connecting) rod 8 are made contact matching up and down, assemble dish type ratchet rocker 9 and ratchets 10 with bearing pin 19 on the pair of right and left synchronising (connecting) rod 8, assemble ratchets 11 with key 13 on the axle 12, ratchet 10 and ratchet 11 are rotatably assorted as orientation, spring 22 two ends are separately fixed on synchronising (connecting) rod 8 and the housing 21, and synchronising (connecting) rod 8 is in time resetted after finishing luffing.Referring to Fig. 3, this is a two ends stationary cam 6 and 4 on speed reduction unit 3 output shafts, synchronizedly runs.Referring to Fig. 4 and Fig. 5, this is two cams synoptic diagram of assembling synchronously, the change angle α of cam 4 low spot lofty perch lifts is in 100 ° ± 5 °, be in the luffing duty this moment, another scope on the full circle of cam 4, promptly in 360 °-100 ° ± 5 °=260 ± 5 °, make former 14 be in the location display state, in like manner in 100 ° ± 5 ° of the corresponding angle α of positioning cam 6, being in low spot does not work, make former 14 be in rotary state, and be in the location duty in 260 ° ± 5 ° of another scopes on the full circle of cam 6, even former 14 location are showed.Referring to Fig. 6, be that C-C cuts open among Fig. 2, be fixed on the installing plate 20 in the housing 21, with bearing assembled shaft 12, a pair of ratchet rocker 9 usefulness bearings are assemblied on the axle 12, it is keyed on the axle 12 with the coaxial ratchet 11 of ratchet rocker 9, and ratchet rocker 9 and ratchet 10 usefulness bearing pins 19 are assemblied in the synchronising (connecting) rod 8 that section takes the shape of the letter U, one of in a pair of synchronising (connecting) rod 8 as the power synchronising (connecting) rod.Axle 12 other ends are connected former end socket 15 with screw with shaft collar, former end socket 15 is fixed on former 14 ends, and the former 14 that section is equilateral triangle rotates with axle 12.Referring to Fig. 7, this is horizontal former 14 exploded views.Referring to Fig. 8, this is vertical former 14 exploded views.Whole principle of work is like this: after motor 1 starting, through slowing down, cam 4 that rotates and cam 6 rotating speeds are reduced to per minute 4.8～5 synchronously changes, luffing cam 4 rotation activation lever 5, compressing lever 5 other ends promote synchronising (connecting) rod 8 and move upward, ratchet rocker 9 hinged on connecting rod 8 is rotated counterclockwise, the 10 pairs of ratchets 11 of a pair of ratchet that drive on the synchronising (connecting) rod 8 are made counterclockwise directional push, make ratchet 11, after axle 12 and former 14 rotate 120 °, stop operating immediately, synchronising (connecting) rod 8 resets rapidly under the effect of spring 22, this moment, cam 4 and 6 was to rotate always, one of three faces of former 14 are promptly showed, in order to guarantee a plurality of former 14 unified rotations and to show a leveling face, just need be to former 14 location, after cam 4 is rotating 100 ° ± 5 °, cam 6 is promptly started working, promote lever 7 upwards, lever 7 other ends are moved down, driving hinged pull bar 16 and locating sleeve 17 moves down, the conical surface compressing location-plate 18 of locating sleeve 17 rotates, make the triangle draw-in groove of location-plate 13 1 sides snap in 14 1 jiaos of formers, 14 whole location of former are showed, cam 6 orientation angles are 260 ° ± 5 °, when cam 4 entered the luffing state once more, location-plate 18 broke away from positioning states under self action of reset spring, set back.The upset of former 14 and location show that time ratio is 100 like this: ± 260=1: 2.6 with cam 4 and 6 per minutes rotation, 5 circle calculating, and revolution 1 circle is for overturning and location displaying one-period about 12 seconds.

Advantage of the present utility model and effect are as follows:

1, the exhibiting device because the employing mechanical type overturns is so overcome former fixed one The weak point of display surface has three width of cloth Graphic Panels automatically by the certain hour punctuated turning over The characteristics of showing, this upset displaying time can come by the rotating speed of adjusting cam 4 and 6 Control has improved three times displaying content.

2, the displaying of this device can be used under multiple occasion, according to client's need , it is changeable to be designed and manufactured into breadth, and breadth adopts vertical or horizontal, breadth Both can adopt big plane, perhaps adopt the configuration of two sided angle, have the spy of flexible assembling The point.

3, owing to adopt three width of cloth upset Graphic Panel, the time that the location is showed is greater than flip-flop transition, so adapt to people's visual custom, have bandwagon effect preferably, three formers can be showed three different contents, if additional necessary light, spectators are come into plain view, high-visible.

4, easy to maintenance, in maintenance process, do not influence former and show, and show that the content replacing is also convenient, further improved service efficiency, and because periodic upset makes former have certain air permeability, so improved the security of use.

5, the utility model is applied in industries such as advertising sector, information widely, has certain social benefit and economic benefit.
