Description
Technical field
The utility model relates to the projection ball for building curtain that a kind of cinema uses, and is applicable to play various spherical screen stereoscopic films etc., can be used for each exhibition advertising and uses etc.
Background technology
Current ball curtain has two kinds, hard ball curtain and inflation soft body ball curtain, and software dome is to adopt through the flexible curtain material of cutting to be spliced, and the shape of cutting is through professional calculation software design.By flexible ball curtain is fixed on ground, between ball curtain and ground, form confined space, then with fan blower to blowing and make to produce pressure reduction inside and outside ball curtain between ball curtain and ground, so that ball curtain becomes is spherical.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 have all been subject to serious test.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of bleeder ball curtain.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of bleeder ball curtain, comprise and be supported on ground support, also be provided with and be positioned on support and inflation bag that profile is spherical in shape, also be provided with projection screen, the lower edge of described inflation bag, together with the edge seal of projection screen, has formed the sealed cavity between inflation bag and projection screen, is also provided with the aspiration pump that is communicated with this cavity.
Preferably, described projection screen and inflation bag are sealed by VELCRO.
Preferably, described inflation bag is fixed on support by sucker, and one end of described sucker is adsorbed on the surface of inflation bag, and the other end is tied up on support by fixed band.
Projection ball of the present utility model curtain, when in use, opens aspiration pump, and the air in sealed cavity is extracted out, and projection screen is attached to the inside surface of inflation bag under negative pressure, finally forms needed projection sphere, and it is very convenient to use.
Brief description of the drawings
Fig. 1 shows the explosive view of the utility model projection ball curtain.
Fig. 2 shows the structural representation of the utility model projection ball curtain.
Embodiment
For the technical matters that the utility model is solved, the technical scheme of employing, the technique effect easy to understand of obtaining, below in conjunction with concrete accompanying drawing, embodiment of the present utility model is described further.
With reference to figure 1, Fig. 2, the disclosed a kind of bleeder ball curtain of the utility model, it is made up of support 7, inflation bag 1, projection screen 4.
On the ground, for whole projection ball curtain provides support, the outline entirety of inflation bag 1 is spherical in shape for support 7 fixed supports, and certainly, the shape of inflation bag can need to be selected according to actual design, and it is fixed on support 7.In preferred embodiment of the utility model, described inflation bag 1 is fixed on support 7 by sucker 2, and one end of described sucker 2 is adsorbed on the surface of inflation bag 1, and the other end is tied up on support 7 by fixed band 8.
The shape of projection screen 4 needs and inflation bag 1 matches, and when installation, together with the edge seal of the lower edge of described inflation bag 1 and projection screen 4, has formed the sealed cavity between inflation bag 1 and projection screen 4, is also provided with the aspiration pump 6 that is communicated with this cavity.
Projection ball of the present utility model curtain, when in use, opens aspiration pump 6, and the air in sealed cavity is extracted out, and projection screen 4 is attached to the inside surface of inflation bag 1 under negative pressure, finally forms needed projection sphere, and it is very convenient to use.
Select the suitable dimension of projection screen 4, make projection screen 4 in forming projection sphere, it maintains a certain distance etc. with the inside surface of inflation bag 1.
In an embodiment of the present utility model, described projection screen 4 and inflation bag 1 are sealed by VELCRO 3.
The utility model is by preferred embodiment having carried out detailed explanation.But ,-by studying carefully above, the variation to each embodiment and to increase be apparent for one of ordinary skill in the art.Being intended that all these variations and increasing of applicant all dropped in the scope that the utility model claim protects.
