Abstract
The invention relates to a large-breadth horizontal curtain pulling device which comprises a structure support, a curtain cloth, a curtain cloth unwinding mechanism and a curtain cloth winding mechanism. The structure support forms a cavity. A solid model base disc is placed on the bottom face of the cavity. A solid model is displayed on the solid model base disc. The curtain cloth unwinding mechanism used for unwinding the curtain cloth is arranged above one side of the cavity. The curtain cloth winding mechanism used for winding the curtain cloth is arranged above the other side, corresponding to the side, of the cavity. The curtain cloth is wound on the curtain unwinding mechanism. When a projection sand disc needs to be projected, a transmission unit controls rollers to start, a roller on one side is in charge of pulling, a roller on the other side is in charge of pushing, the two rollers operate synchronously, and accordingly the fact that no folding exists on the projection curtain cloth is guaranteed. After projection, audiences can see the solid model below the curtain cloth which is wound, and perfect combination of the projection digital sand disc and a solid sand disc in space is achieved.
Description
Technical field
The present invention relates to the required horizontal projection curtain of a kind of digital projection sand table, relate in particular to a kind of moving and draw hiding large format level to move curtain-drawing device.
Background technology
When making the digital projection sand table, generally all adopt fixed projection hard curtain at present.When not watching the digital projection sand table, the hard curtain influence of the white of large format is attractive in appearance, does not have effect when particularly closely seeing, wasting space, and generally inapplicable under the situation that requires the solid model sand table.Therefore, the technical scheme that the digital projection sand table does not adopt projection hard curtain be need seek to make, digital sand table and solid model sand table space solved in the problem of last combination.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of large format level to move curtain-drawing device.
Purpose of the present invention is achieved through the following technical solutions:
The large format level is moved curtain-drawing device, characteristics are: comprise structure stand, curtain, curtain unreeling structure and curtain rolling-up mechanism, described structure stand forms a cavity, the solid model chassis is placed in the bottom surface of cavity, solid model displays solid model on the chassis, the top of one side of cavity is provided be used to the curtain unreeling structure of putting the exhibition curtain, and the top of the another side of the cavity corresponding with it is provided with for the curtain rolling-up mechanism of regaining curtain, and curtain is wound on the curtain unreeling structure.
Further, above-mentioned large format level is moved curtain-drawing device, described curtain unreeling structure and curtain rolling-up mechanism all comprise a cylinder, a gear unit, a clutch unit and a variable-speed unit, and cylinder connects variable-speed unit, and variable-speed unit connects gear unit by clutch unit.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
Adopt large-scale level to move draw curtain, the upper horizontal at solid model when being fully withdrawn is paved with the projection screen of white as the projection screen of digital projection sand table.In the both sides of moving draw curtain cylinder is set, curtain is packed up or level is paved with.When need projection projection sand table, the gear unit index drum starts, and one sidewinders the responsible receipts of tube, and the opposite side cylinder is responsible for putting, and both synchronous operations guarantee the projection screen unfolded.After projection finishes, pack up the solid model that the back spectators can see that curtain is beneath equally, realized projection digital sand table and the perfect adaptation spatially of entity sand table.Realized that the digital projection sand table is combined with the space of entity sand table, saved the space of showing.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: structural representation of the present invention.
Embodiment
As shown in Figure 1, the large format level is moved curtain-drawing device, comprise structure stand 1, curtain 5, curtain unreeling structure 4 and curtain rolling-up mechanism 6, structure stand 1 forms a cavity, solid model chassis 2 is placed in the bottom surface of cavity, display solid model 3 on the solid model chassis 2, and the top of a side of cavity is provided be used to the curtain unreeling structure 4 of putting the exhibition curtain, the top of the another side of the cavity corresponding with it is provided with for the curtain rolling-up mechanism 6 of regaining curtain, and curtain 5 is wound on the curtain unreeling structure 4.
Curtain unreeling structure 4 and curtain rolling-up mechanism 6 all comprise a cylinder, a gear unit, a clutch unit and a variable-speed unit, and cylinder connects variable-speed unit, and variable-speed unit connects gear unit by clutch unit.
Adopt large-scale level to move draw curtain, the upper horizontal at solid model 3 when being fully withdrawn is paved with the projection screen of white as the projection screen of digital projection sand table.In the both sides of moving draw curtain cylinder is set, curtain is packed up or level is paved with.When need projection projection sand table, the gear unit index drum starts, and one sidewinders the responsible receipts of tube, and the opposite side cylinder is responsible for putting, and both synchronous operations guarantee the projection screen unfolded.After projection finishes, pack up the solid model that the back spectators can see that curtain is beneath equally, realized projection digital sand table and the perfect adaptation spatially of entity sand table.Having solved the digital projection sand table needs the problem of the projection hard curtain wasting space of large space, has realized that the digital projection sand table is combined with the space of entity sand table, has saved the space of showing.
What need understand is: the above only is preferred implementation of the present invention; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
