Accompanying drawing explanation
Fig. 1 is the side view that the utility model can repeat the demonstration built fast;
Fig. 2 is the side view of the utility model liftable unit.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation that the utility model can repeat the demonstration built fast, and as shown in Figure 1, the described demonstration that can repeat to build fast comprises the sand dish controls main frame 10, sand table hoistable platform 20 and projection unit 40, wherein:
Described the sand dish controls main frame 10 is electrically connected with described sand table hoistable platform 20 and the unit 40 that projects respectively, for controlling the height and position of each liftable unit in described sand table hoistable platform 20, and texture image information is sent to described projection unit 40;
Described sand table hoistable platform 20 comprises multiple liftable unit and covers the elastic film 30 be fixedly connected with on described multiple liftable unit and with described liftable unit;
Wherein, each liftable unit is all connected with the bottom of described sand table hoistable platform 20.
In the utility model one embodiment, the xsect of described liftable unit is rectangular, certainly, also can be other any rational shapes.
In the utility model one embodiment, described multiple liftable unit is m × n (such as 40 × 40), arrange in matrix, certainly, also can arrange according to other any rational forms, as long as can be distributed on sand table hoistable platform 20, and different landform can be embodied by lifting.
Fig. 2 is the structural representation of the utility model liftable unit, and as shown in Figure 2, each liftable unit 20 comprises drive motor 21, gangbar 22, rectangular post 23 and riveting set 24 from the bottom to top successively, wherein:
Described rectangular post 23 is connected with described drive motor 21 by gangbar 22, thus realize moving up and down of rectangular post 23 by the driving force of described drive motor 21, the concrete height and position of described rectangular post 23 is controlled by described the sand dish controls main frame 10, in the utility model one embodiment, the height moving range of described rectangular post 23 is between 0-0.5 rice;
