Abstract
The utility model discloses a bleeder spherical projection curtain, subaerial and have a support of spheric profile including supporting the ball curtain inner bag that matches with the support shape is hung to the inboard of support the outside of support is equipped with ball curtain dustcoat, being in the same place with the bottom mounting of ball curtain dustcoat in the bottom of ball curtain inner bag, forms sealed appearance chamber, still including this aspiration pump that holds the chamber of intercommunication. The utility model discloses a bleeder spherical projection curtain bleeds through the aspiration pump, forms the negative pressure at sealed appearance intracavity for ball curtain dustcoat and ball curtain inner bag adsorb together, have finally realized the expansion of ball curtain inner bag, make the curtain face shaping of ball curtain. The utility model discloses a projection curtain, its simple structure, the installation is dismantled conveniently.
Description
Technical field
The utility model relates to a kind of projection spherical curtain for building of cinema, be applicable to play various spherical screen stereoscopic films etc., space science center can be used in widely, in astronomical observatory, seismological bureau, the places such as NASA, school, museum, by the manifestation mode such as animation and image, show the content such as the relevant earth, satellite, planet, earthquake, ocean, air, the sun.
Background technology
Current ball curtain has hard ball curtain and two kinds, inflation soft body ball curtain, and software dome adopts the flexible curtain material through cutting to be spliced, and the shape of cutting is through professional calculation software design.By being fixed on ground by flexible ball curtain, between ball curtain and ground, forming confined space, then making to produce pressure reduction inside and outside ball curtain to blowing between ball curtain and ground with fan blower, becoming spherical to make ball curtain.There is certain problem in the ball curtain of this form, because ball curtain is mounted on ground, therefore the security of ball curtain and stability all receive serious test.What is more important, this spherical curtain installation and removal are very inconvenient.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of bleeder spherical projection curtain.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of bleeder spherical projection curtain, comprise support on the ground and there is the support of spheric profile, the ball curtain inner bag with support form fit is hung with in the inner side of described support, ball curtain outer cover is provided with in the outside of described support, the bottom of described ball curtain inner bag and the bottom of ball curtain outer cover are fixed together, and form the cavity volume of sealing; Also comprise the aspiration pump being communicated with this cavity volume.
Preferably, the bottom of described ball curtain inner bag and the bottom of ball curtain outer cover are bonded together by VELCRO.
Bleeder spherical projection curtain of the present utility model, is bled by aspiration pump, forms negative pressure, ball curtain outer cover and ball curtain inner bag are attached together, finally achieve the expansion of ball curtain inner bag, make ball curtain curtain face shaping in the cavity volume of sealing.Projection screen of the present utility model, its structure is simple, easy installation and removal.
