Preferably, described Portable movable projection screen, also comprises:
Three supporting legs, the base plate of described box body caves inward the holding tank of formation one strip, three parallel inside being placed on described holding tank of supporting leg, one of them supporting leg is pivoted to the side of described holding tank, another two supporting legs are pivoted to the opposite side of described holding tank, when three supporting legs are all switched to the outside of described holding tank, support described box body.
Preferably, in described Portable movable projection screen, described bag shaped structure is under unaerated state, and described air pump is positioned over described tray interior, and the opening of described box body is covered with a lid; The opposite side of described box body has a door able to turn on or off; Described inflation inlet is arranged on described rear portion.
Preferably, in described Portable movable projection screen, described front portion is made up of square air impermeability material, and the air impermeability material forming described front portion is light tight, elastic deformation is there is not in gas replenishment process, described rear portion is also made up of airproof soft material, and area anterior described in the area ratio at described rear portion is large.
Preferably, in described Portable movable projection screen, described box body has a rectangular shaped rim in open side, and the arranged outside of described rectangular shaped rim has black flannelette.
Preferably, in described Portable movable projection screen, the rear side of described front portion has the strip shaped air sac of multiple horizontal and vertical layout, each strip shaped air sac is connected to described air pump, described bag shaped structure in the deflated condition time, multiple strip shaped air sac is also in inflated condition, and supports described front portion, and described front portion is launched.
Portable movable projection screen provided by the present invention has following beneficial effect: the present invention devises an inflatable part, it comprises and to be connected to each other the air-locked bag shaped structure formed by front and rear, when bag shaped structure is under inflated condition, anterior expansion formation one screen, after inflation, screen is just in the state tightened; Further, inflatable part is arranged in box body, and in a state of use, box body can play the effect of fixing inflatable part, and under non-working condition, box body then plays the effect holding each parts of projection screen, improves the portability that projection screen uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of Portable movable projection screen of the present invention;
Fig. 2 is the structural representation of inflatable part of the present invention;
Fig. 3 is the structural representation of holding tank of the present invention;
Fig. 4 is the structural representation of anterior rear side of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to instructions word to make those skilled in the art.
As depicted in figs. 1 and 2, the invention provides a kind of Portable movable projection screen, comprise: inflatable part, it comprises and to be connected to each other the air-locked bag shaped structure formed by anterior 2 and rear portion 7, and described bag shaped structure has the inflation inlet for being connected with air pump, described bag shaped structure in the deflated condition, launch to form screen by described front portion; Box body 1, its side has opening; Wherein, described inflatable part is arranged on the inside of described box body, and described anterior 2 to be exposed to the outside when described bag shaped structure is under inflated condition.
When projection screen of the present invention uses, first utilize air pump 4 to the inner inflatable of bag shaped structure, when bag shaped structure gassy, front portion is launched and is in the state tightened, thus forms a screen.When bag shaped structure is filled gas, box body 4 provides fixing for inflatable part and supports, and makes inflatable part be not interposing at overturning.
In order to adapt to the needs of different occasion, described Portable movable projection screen, also comprise: three supporting legs 3, the base plate of described box body 1 caves inward the holding tank 5 of formation one strip, three parallel inside being placed on described holding tank 5 of supporting leg 3, one of them supporting leg is pivoted to the side of described holding tank, and another two supporting legs are pivoted to the opposite side of described holding tank, when three supporting legs are all switched to the outside of described holding tank, support described box body (see Fig. 3).Namely under using state, three supporting legs are pivoted to the outside of holding tank, for box body provides support; Under non-working condition, three supporting legs are just accommodated in holding tank, and can be fixed by holding firmware, do not take unnecessary space.
In described Portable movable projection screen, described bag shaped structure is under unaerated state, and described air pump is positioned over described tray interior, and the opening of described box body is covered with a lid; The opposite side of described box body has a door able to turn on or off; Described inflation inlet is arranged on described rear portion.Under non-working condition, inflatable part is in flat state, can not take a lot of spaces, now, air pump also can be accommodated into tray interior; And for the ease of carrying, also at the vent cover unification lid of box body.In a state of use, the opposite side of box body is also provided with door, opens door, is taken out by air pump, and to bag shaped structure inflation, sack-like element inflation, fills up the space of tray interior.
In order to the screen making anterior formation one comparatively smooth, and outwards do not heave, in described Portable movable projection screen, described anterior 2 are made up of square air impermeability material, and the air impermeability material forming described front portion is light tight, in gas replenishment process, elastic deformation does not occur, described rear portion 7 is also made up of airproof soft material, and area anterior described in the area ratio at described rear portion 7 is large.The material of anterior 2 can adopt white plastic.
In described Portable movable projection screen, described box body has a rectangular shaped rim in open side, and the arranged outside of described rectangular shaped rim has black flannelette.The scattering that black flannelette is not reflective, light can not occur, the image being projected on screen edge can distinguish with surrounding environment well, and can not have influence on appreciation effect.
As shown in Figure 4, in described Portable movable projection screen, the described rear side of anterior 2 has the strip shaped air sac 6 of multiple horizontal and vertical layout, each strip shaped air sac 6 is connected to described air pump, described bag shaped structure in the deflated condition time, multiple strip shaped air sac is also in inflated condition, and supports described front portion, and described front portion is launched.Launching comparatively smooth to make front portion as far as possible, outwards not heaving, fore rear side arranges multiple strip shaped air sac, and after be full of gas in strip shaped air sac, strip shaped air sac just plays the effect of support to front portion.
Although embodiment of the present invention are open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
