Concrete structure of the present utility model as shown in Figure 2, straight line is provided with axle sleeve 21 equidistantly on the left side brackets 23 of framework 1, shaft room is apart from the width that equals positive three prism 26, on the left side brackets 30 of framework 1, be provided with axle sleeve 15 symmetrically with left side axle sleeve 21 relevant positions, the both sides 27 of each positive three prism 26 are provided with

central shaft

20,16 and 21,15 one-tenth movingly, guarantee that positive three prism 26 is free to upset, positive three prism 26 is installed on the support 23,30 of display device and constitutes display plane.

Each positive three prism 26 is driven by synchronous switching mechanism, does upset synchronously, and switching mechanism comprises turning wheel synchronously, and 14,31 and chain bar 33.Connect the eccentric wheel 32 on all rollovers wheel, guarantee upset synchronously, bottom eccentric wheel 14, different with other turning wheel 31, it is an eccentric gear, is meshed with driven wheel 11.

Intermittent drive mechanism comprises driven

wheel

11,9 and imperfect gear 35, driven wheel 11 is meshed with turning gear 14, speed ratio is 1:1, and it is coaxial with driven wheel 9, driven wheel 9 is meshed with imperfect 35, as Fig. 5, there is tooth on the top, calibration garden of imperfect gear 35, remainder is smooth, imperfect gear 35 designs with the speed ratio quiescent interval and the reversal rate as required of driven wheel 9, and this speed ratio has guaranteed that display frame has gone out a picture in the time inner conversion that imperfect gear turns around, and a period of time at intermittence.

The batch (-type) driving mechanism is driven by reducing gear, and reducing gear adopts worm gear reducer and belt to slow down, and above-mentioned imperfect gear 35 and deceleration worm gear 17 are coaxial 18, and the belt pulley 19 that links to each other with deceleration worm gear 17 is by belt 28 connection motor 29.The structure of relevant deceleration worm gear case belongs to known technology, so be not described in detail.

More than described the mechanical mechanism of a kind of specific embodiment of the present utility model, now its principle of work be explained as follows:

Open motor, by belt pulley, behind the worm gear reducer, drive the rotation of imperfect gear, imperfect gear whenever revolve turn around in, when it has toothed portion to be meshed with driven wheel 9, drive driving wheel and change 1/3 circle, when it did not mesh, driven wheel 9 was static, like this, image turning once in imperfect gear revolves the time of turning around, and static a period of time, by adjusting the speed ratio that changes imperfect gear 35 and driven wheel 9, can determine image turning time and rest time.In the imperfect gear shared ratio of required time that whenever turns around, if the number of teeth of driven wheel is 30, through experiment, under the identical situation of modulus, when if the speed ratio of imperfect gear and driven wheel is 7:1, imperfect gear has the number of teeth of toothed portion to should be 8, and when being 3:1 as if speed ratio, the toothed portion that has of imperfect gear should be 10.

If the rotating speed of motor is 960 rev/mins, the belt pulley speed ratio is 4:1, the worm gear speed ratio is 40:1, then the rotating speed of motor is 960 * 1/4 * 1/40=6 rev/min behind double reduction, be the rotating speed of imperfect gear 35, the time that imperfect like this gear whenever turns around is 10 seconds, in a circle, when imperfect gear 35 meshes with driven wheel 9, driving driven wheel 9 changes 1/3 circle, and driven wheel 11 drives turning gear 14 changes 1/3 circle, by synchronous switching mechanism, make all positive three prisms change 1/3 circle, the display frame conversion once; Correspondingly when imperfect gear 35 does not mesh with driven wheel 9 in this circle, driven wheel 9 does not rotate, then display frame remains static, if when getting the speed ratio of imperfect gear and driven wheel and being 7:1, then image turning actuation time is 10/7=1.4 second, and the picture still time is 10-1.6=8.6 second.

Motor constantly rotates, display frame every conversion in 10 seconds once, the batch (-type) driving machine has guaranteed the every change of picture once, carries out conversion next time after static a period of time again.Three faces of positive three prism are turned to the front successively, demonstrate three different pictures, after three circles, repeat to show, so move in circles.Reach the batch (-type) purpose that three-picture shows of overturning automatically.

As Fig. 6, shown in Figure 7, switching mechanism also can adopt gear set for the chain bar synchronously, all change all rollovers wheel 31 into the turning gear group, connect with power wheel 34 between each turning gear, transmission gear and turning gear speed ratio are 1:1, its principle of work is identical with the chain linkage, no longer describes at this.

The utility model compared with the prior art, its advantage and good effect are to adopt motor to be used as power, make a display unit can show simultaneously three different pictures, and the variation of picture is the batch (-type) automatic turning, change the quantity of triangular prism, the numerical value such as wide, long, but the area arbitrary size of display plane. And this machinery adopts the Purely mechanical structure, and the many pictures with electronic type display unit change function automatically, but its structure and cost are lower than the electronic type display unit. Although than fixed display device structure complexity, the cost height, its function increases greatly. Can say that the utility model is a kind of novel display unit between fixed and electronic type display unit. It is applicable to the various demonstrations places such as advertisement, publicity.
