The length of ontology,
Projection screen sub-assembly, including：
Box is rolled up, the top of the door-shaped frame is fixed at；
Wind spring axle, it is concentric to be arranged in the volume box；
Curtain on the Wind spring axle, and can be pierced by the opening being formed on volume box；
First fixing piece is fixed at the end of curtain；
Second fixing piece is fixed at sand table bodies top front end, and matches with first fixing piece.
Further, the front end of the sand table ontology is fixed with the first limiting plate being vertically arranged, the sand table ontology
Tail portion be fixed with horizontally disposed second limiting plate.
Further, the sand table ontology is equipped with limiting bracket, and the limiting bracket passes through connecting shaft and the sand table
Ontology is rotatably connected, and the bottom end of the door-shaped frame is equipped with limiting slot, when limiting bracket is in vertical state, limiting bracket
Top is stuck in the limiting slot.
Compared with prior art, the utility model has the beneficial effects that：
1, the setting of rotatable door-shaped frame so that the present apparatus can be at vertically and horizontally different states, when it is in
When horizontal receiving state, it is not take up additional space, it is current when being in vertical working condition, it can be projected, carry out multimedia
Displaying, functional diversities.
2, mechanism reasonable design, manufacturing cost is low, easy to utilize.
Description of the drawings
Fig. 1 show the structural schematic diagram of the utility model door-shaped frame horizontality.
Fig. 2 show the structural schematic diagram of the utility model door-shaped frame vertical state.
Fig. 3 is the structural schematic diagram of projection screen sub-assembly.
Wherein：1- sand table ontologies, 2- projector mechanisms, 3- mounting brackets, 4- rotary shafts, 5- revolving parts, 6- door-shaped frames, 7- volumes
Box, 8- curtains, 9- Wind spring axles, the first fixing pieces of 10-, the second fixing pieces of 11-, the first limiting plates of 12-, 13- limiting brackets,
14- connecting shafts, the second limiting plates of 15-, 16- limiting slots.
Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figs. 1-3, a kind of multimedia show sand table of the utility model, including：
Sand table ontology 1：
Projector mechanism 2 is arranged by rotary shaft 4 on the mounting bracket 3 of 1 tail portion of sand table ontology；
Door-shaped frame 6, bottom end are rotatably connected by revolving part 5 with the front end of the sand table ontology 1, and length is more than the sand
The length of disk ontology 1,
Projection screen sub-assembly, including：
Box 7 is rolled up, the top of the door-shaped frame 6 is fixed at；
Wind spring axle 9, it is concentric to be arranged in the volume box 7；
Curtain 8 on the Wind spring axle 9, and can be pierced by the opening being formed on volume box 7；
First fixing piece 10, is fixed at the end of curtain 8；
Second fixing piece 11, is fixed at 1 top nose 11 of sand table ontology, and with 10 phase of the first fixing piece
Match.
Working method：
As shown in Fig. 2, when carrying out multimedia show using the present apparatus, door-shaped frame 6 is rotated, makes it perpendicular to sand table ontology
1, the first fixing piece 10 is pulled, curtain 8 is pulled out out of volume box 7, and the first fixing piece 10 is fixed on the second fixing piece 11,
Such curtain 8 is unfolded, and starts projector mechanism 2, you can carries out multimedia show.
When without using multimedia show, the first fixing piece 10 is removed from the second fixing piece 11, curtain 8 is rolled up in spring
It under the rebound effect of axis 9, wraps back in volume box 7, as shown in Figure 1, rotation door-shaped frame 6, makes it be sleeved on the frame of sand table ontology 1
