Fig. 2 illustrates the structural representation of Quick distributor of the present utility model projection vault curtain.
Wherein, above-mentioned accompanying drawing includes the following drawings labelling:
10, framework is supported；20, rainproof layer；11, gateway；12, door curtain.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
It it is noted that described further below is all exemplary, it is intended to provide further instruction to the application.Unless otherwise, all technology used herein and scientific terminology have the identical meanings being generally understood that with the application person of an ordinary skill in the technical field.
In this utility model, when not making contrary explanation, the noun of locality of use if " upper and lower, top, the end " is usually for direction shown in the drawings, or for parts this on vertical, vertical or gravity direction；Similarly, for ease of understanding and describing, it is inside and outside that " inside and outside " refers to relative to the profile of each parts itself, but the above-mentioned noun of locality is not limited to this utility model.
The problem high for solving ball screen cinema cost of the prior art, this utility model provides a kind of Quick distributor projection vault curtain.
As depicted in figs. 1 and 2, Quick distributor projection vault curtain includes supporting framework 10, rainproof layer 20 and projection screen, supporting framework 10 is hemispherical after inflation, rainproof layer 20 is set in the outside supporting framework 10, rainproof layer 20 and the sealed bottom bonding supporting framework 10, projection screen fits in the inside supporting framework 10, the edge of projection screen and the sealed bottom bonding supporting framework 10, and the air entry of negative pressure-pumping machine is arranged between rainproof layer 20 and projection screen.
First in the outside supporting framework 10 sheathed good rainproof layer 20 and so as to the sealed bottom bonding supporting framework 10, from the inside supporting framework 10, the edge of projection screen and the sealed bottom supporting framework 10 are bonded, then support framework 10 is inflated, inflation rear support framework 10 is hemispherical, finally start negative pressure-pumping machine, along with negative air between rainproof layer 20 and projection screen is constantly drawn out of, internal air pressure diminishes, the projection screen originally hung down on ground is made to be sucked up and be fitted in the inside supporting framework 10 under the effect of atmospheric pressure, thus forming dome ball curtain, now namely can be used to play film or demonstration astronomical phenomena.Quick distributor of the present utility model projection vault curtain overall structure is simple, builds conveniently, cheap, and support framework 10 after being deflated, support framework 10, rainproof layer 20 and projection screen and can be conveniently carried out folding, preserve and carry, lightweight, there is good mobility.
Preferably, negative pressure-pumping machine is arranged at the top of Quick distributor projection vault curtain so that each position of projection screen with support framework 10 and fit to obtain uniform close more.
As it is shown in figure 1, supporting framework 10 is hollow type.By arranging support framework 10 for hollow type, it is thus possible to effectively save material, reduce processing cost.
Preferably, support framework 10 to be formed by hot jet welding by 0.6 millimeter of PVC gastight material, the tension of material own, anti tear, intensity and air-tightness are all very good, can in minutes fast aeration shape, shape within latter 48 hours not reinflated, gas column air pressure inside is lost less than 10%, therefore can use continuously for a long time.
Preferably, rainproof layer 20 is oxford, has good rainproof effect, and material is solid, it is possible to the impact of the general foreign body that opposing is extraneous.
