Depression.
In the present invention, when not using, screen yardage roll in screen rotating shaft, in cup.When it is desired to be used, control
Motor drives screen axis of rotation, puts down screen cloth.After screen cloth puts down, charge valve is inflated.Because screen cloth is double
After layer cloth structure, is connected between layer cloth by elastic strip, therefore inflation is finished, due to the presence of elastic strip, screen cloth will be
Caved inward on vertical direction.Under the projection of projecting apparatus, due to the presence being recessed, the user of the projection screen left and right sides is clear
See the clear pattern of opposite side.It is also an advantage of the present invention that, after the inflation of screen cloth, can effectively reduce to a certain extent and be
It is bent upwards to elimination screen cloth and is rolled.
As a preferred mode, the least significant end of the screen cloth is provided with screen end axle, is cased with the axle of the screen end
Gravity rod.Screen end axle is provided with by the least significant end of screen cloth, gravity rod is cased with the axle of screen end, in the Action of Gravity Field of gravity rod
Under, can effectively eliminate screen cloth and be bent upwards and roll.
As a preferred mode, the one of the gravity rod is terminated with aerating device, and the charge valve is arranged at screen
Cloth bottom is at aerating device.Aerating device is terminated with by the one of gravity rod, charge valve is arranged at screen cloth bottom and is close to
At aerating device, it is easy to be inflated operation in routine use.
As a preferred mode, the stack shell top of the cup is provided with link.It is provided with by the stack shell top of cup
Link, is easy to be hung on cup on wall, convenient use.
As a preferred mode, the quantity at least two of the link.By the quantity at least two of link,
The stability of cup suspension can be ensured, it is to avoid incline to side.
As a preferred mode, the screen cloth two sides is equipped with reflector layer.It is equipped with instead by screen cloth two sides
Photosphere, is capable of achieving screen cloth two sides Jun Neng normal projections, in use, can choose at random.
As a preferred mode, the screen cloth vertical direction centerline be recessed it is most deep, to the left and right both sides by
Gradually successively decrease, the ratio between maximum and screen cloth width value of its cup depth are 0.02~0.05.In general, screen cloth surface is got over
Smooth, its drop shadow effect is better.It is recessed in vertical direction centerline by screen cloth most deep, both sides are gradually successively decreased to the left and right,
The ratio between maximum and screen cloth width value of its cup depth are 0.02~0.05, clear in the user for ensureing the screen left and right sides
While seeing opposite side clear pattern, its depression amplitude is small, for the user of direct vision screens cloth, can not discover substantially,
Small is influenceed on drop shadow effect.
The present invention compared with prior art, with advantages below and beneficial effect：
(1) user for assisting in the projection screen left and right sides of the invention is clearly apparent the clear pattern of opposite side；
(2) present invention is provided with screen end axle by the least significant end of screen cloth, gravity rod is cased with the axle of screen end, in gravity rod
Action of Gravity Field under, can effectively eliminate screen cloth and be bent upwards and roll；
(3) present invention is terminated with aerating device by the one of gravity rod, and charge valve is arranged at screen cloth bottom near inflation
At device, it is easy to be inflated operation in routine use；
(4) present invention is most deep in vertical direction centerline depression by screen cloth, and both sides are gradually successively decreased to the left and right, and its is recessed
It is 0.02~0.05 to fall into the ratio between maximum and screen cloth width value of depth, is clearly apparent in the user for ensureing the screen left and right sides
While opposite side clear pattern, its depression amplitude is small, for the user of direct vision screens cloth, can not discover substantially, to throwing
Shadow influential effect is small.
