Abstract
The utility model discloses a crimp projection screen for projecting which comprises a polycarbonate base plate whose surface is provided with an optic layer. The utility model has the advantages of high resistance to impact and good toughness, and all procedures, such as split jointing of polycarbonate plates, can be accomplished in factory, the forming screen can be shaped in arc, split jointing can make the two cutting oblique planes of two adjacent polycarbonate plates split jointed again forming seamless split joint, thereby not affect using, the utility model can be coiled as cylinder shape and is convenient to carried. The polycarbonate plate of the utility model is provided with a reinforced rib on the opposite side, thereby can advance and maintain the planeness and shape of the projection screen, convenient to coil the utility model as cylinder shape and in favor of strengthening portable effect.
Description
Technical field
The utility model relates to a kind of projection screen, relates in particular to a kind of scrollable projection hard curtain that can be curved.
Background technology
Present 2 above projectors throw a face altogether and are widely adopted, but projection screen still can not be caught up with its development need, can only adopt following several method: first, stretch tight cashier's office in a shop with soft curtain at metal, this way is used in the short time only, but weak effect and along with variation of temperature, the curtain facial disfigurement has influence on drop shadow effect.Second: hard curtain is just being thrown in field fabrication, just aluminium sheet is fixed on the ready-made framework, is carrying out the surface spray then.Roller coating is handled, this way is that act finishing coat is inhomogeneous, the piebald phenomenon is arranged, and drop shadow effect is not very desirable, along with the variation seam crossing of humiture can crack, site operation serious, engineering time is long, and the curtain face is handled bad, may do over again at any time, the 3rd, adopt this way of unsaturated polyester plate (glass epoxy).Can reach drop shadow effect preferably, but adopt the unsaturated polyester plate to do an act base material, the influence of material can not be made the screen of oversize.
At present at home in the hard curtain of rear-projection, there is not a family can produce two screens that above standard size is seamless spliced, all giant-screen projects can only adopt polylith standard rear projection screen to have the seam connecting method to handle, the problem that all has the physics splicing between every screen, for this reason, some non-important occasion just adopts the soft curtain of rear-projection to realize large-screen splicing, but the defective of the soft curtain of rear-projection often make us also can't be satisfied with, distortion, airflow influence etc.
Summary of the invention
But the utility model provides a kind of can finish manufacturing in factory, have the giant-screen scrollable projection hard curtain that does not have splicing slit effect and portable camber.
The utility model adopts following technical scheme:
A kind of projection scrollable projection hard curtain comprises the polycarbonate substrate plate, is provided with optical layers on the surface of polycarbonate substrate plate.
Compared with prior art, the utlity model has following advantage:
(1) because the utility model is that polycarbonate substrate plate and optical layers are combined with each other, make and the utlity model has that anti-impact force is strong, the advantage of good toughness, and the operations such as splicing of polycarbonate plate all can be finished in factory, and the screen of Xing Chenging can be shaped by arc thus, splicing can be with adjacent two polycarbonate plate incised layer inclined-planes, splice again, form seamless spliced, do not influence use, the utility model can be wound into cylindric, therefore, the utlity model has portable advantage.
(2) the utility model is provided with reinforcement at polycarbonate substrate backboard face, both can improve and keep the flatness and the shape of projection hard curtain, is convenient to again the utility model is rolled into tubular, helps the reinforcement of portable effect.
(3) technical measures of flat board and stripe board can further improve and keep the flatness of projection hard curtain between polycarbonate substrate plate and reinforcement, and the T shape structure that flat board, stripe board and reinforcement constitute, make the utility model can utilize existing hollow sheeting, can finish manufacturing by operations such as simple cutting, splicing, have the simple advantage of manufacturing process at flat board, stripe board and the reinforcement of polycarbonate substrate backboard face.
