Abstract
The utility model discloses a kind of projection screen, including frame and the curtain plate that is arranged on frame, it is characterised in that：A light shield layer is additionally provided between the frame and curtain plate, the frame is located in the light shield layer；The light shield layer is barn door or black-out cloth；Black-out cloth is waterproof cloth.The utility model increases light shield layer between frame and curtain plate, not because of the accumulation of dust if the profile of keel is can't see if even if having a large amount of dust adsorptions on curtain face, influences the reflection of light.After efficiently solving long-time, the black flannelette pasted on keel ensure that projection reflectivity consistency, overall effect are splendid because inhaling the problem of ash is to influence drop shadow effect.
Description
Technical field
The utility model is related to a kind of projection screen faces, especially eliminate ball curtain keel（Frame）On shade caused due to dust
Projection screen face.
Background technology
At present when the installation of large size projection screen, generally use open-work aluminium sheet is processed into screen plate, primarily to acoustics
With echo sound-absorbing.Typically use steel or aluminum keel（Frame）As support, then screen plate is fixed on rivet
On frame.This mounting means is simple and practical.In order to ensure that projection ray makes the consistency of entire ball curtain and light reflection, lead to
Often astigmatism can be absorbed in a manner of pasting black flannelette on keel, ensure that being incident upon in screen for light has similarly instead with this
Penetrate rate.But dust over time, can be filled above keel flannelette, the reflectivity of spine sections can be higher than other parts,
It just will appear shade, and keel profile can also be exposed, thus affect whole effect.
Invention content
Technical problem to be solved in the utility model is in view of the deficiency of the prior art, and to provide one kind and subtract
Few projection screen cleaned and drop shadow effect is good.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of projection screen, including frame and the curtain plate that is arranged on frame, it is characterised in that：In the frame and curtain
A light shield layer is additionally provided between plate, the frame is located in the light shield layer.
The light shield layer is barn door or black-out cloth.
Black-out cloth is waterproof cloth.
The curtain plate is open-work curtain plate.
The open-work curtain plate is open-work aluminum screen plate.
Black-out cloth is attached to double faced adhesive tape on frame.
Open-work aluminum screen plate is fixed on self-plugging rivet on the frame skeleton of frame.
The utility model increases light shield layer between frame and curtain plate, is seen not if even if having a large amount of dust adsorptions on curtain face
To the profile of keel, also the reflection of light is not influenced because of the accumulation of dust.After efficiently solving long-time, pasted on keel
Black flannelette ensure that projection reflectivity consistency, overall effect are splendid because inhaling the problem of ash is to influence drop shadow effect.
Compared with prior art, the utility model has the beneficial effects that：
1, the method effective solution projection screen face for the black-out cloth that the utility model uses can see asking for keel shade
Topic ensures projection result of broadcast.
2, the utility model installs black-out cloth in open-work aluminum screen back so that dust cannot fall into an act face from the back side, subtract
Lack dust accumulation, extended the cleaning frequency of projection, reduces the maintenance cost of projection.
3, the black-out cloth of the utility model can improve the reflecting brightness of screen 1 15 or more, maintain like
Reflecting brightness can improve the service life of projector.
4, the utility model is simple in structure, and one piece of black-out cloth is only added between keel and open-work aluminum screen plate, and
Black-out cloth only needs to be attached on keel with double faced adhesive tape, ensures to develop, stretch, easy to operate, and construction is easy.
5, black-out cloth used in the utility model is easy to get using common light waterproof cloth, material, reduces construction
Transportation cost and purchase cost.

The structural schematic diagram of Fig. 3 frames；
The structural schematic diagram of Fig. 4 curtain plates.
Wherein：1, frame；11, frame skeleton；2, light shield layer；3, curtain face；31, diffusing reflection hole.
Specific implementation mode
Below by implementation and in conjunction with attached drawing, the technical solution of the utility model is further elaborated with.
As shown in Fig. 1, one kind disappears projection screen, including frame 1, light shield layer 2, curtain plate 3, and light shield layer 2 is with curtain plate 3
Rivet is on frame 1.When installation, ensure light shield layer 2 between frame 1 and curtain plate 3, and as far as possible so that light shield layer 2 is bonded
Curtain plate 3, paves and stretches black-out cloth 2, gauffer do not occur, rivet is close.
Light shield layer 2 is selection barn door or black-out cloth.When using black-out cloth, waterproof cloth may be selected, screening can not only be played
Light action, moreover it is possible to waterproof.
The utility model projection screen has no requirement to frame 1 and curtain plate 3.Frame 1 can be according to engine request
Plane can also be curved surface, and curtain plate 3 needs to install according to projection.
