FIG. 1 is a schematic view of the structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a compound projection system of multilayer, including meeting inlayer projection curtain 1, middle level projection curtain 2 and the outer projection curtain 3 that viewing direction set gradually, inlayer projection curtain 1, middle level projection curtain 2 and outer projection curtain 3 are the interval setting, and wherein inlayer projection curtain 1 and middle level projection curtain 2 are penetrating curtain, and outer projection curtain 3 is the impenetrable curtain.
In the utility model, the intervals between the inner layer projection screen 1 and the middle layer projection screen 2 and between the middle layer projection screen 2 and the outer layer projection screen 3 are all 1-1.5 m. Therefore, reasonable space is formed between the projection screens of all layers, on one hand, the corresponding projectors are convenient to arrange, the effective imaging area is increased, and the projectors are favorable for projection; on the other hand, the method is beneficial to the fusion of pictures and has better layering sense and space (three-dimensional) effect when being watched.
In the utility model, the inner layer projection screen 1 and the middle layer projection screen 2 both adopt linen yarns, so that the cost is low, the linen yarns are easy to obtain, the permeability is good, the transmission effect is good, the linen yarns are very light, and the inner layer projection screen can be unfolded or folded, thereby being convenient to install and arrange; the outer layer projection screen 3 adopts linen, is low in cost, easy to obtain, poor in transmission effect, light, expandable and foldable, and convenient to install and arrange.
In the utility model, a first projector 4 capable of projecting to the front side of the inner layer projection screen 1 is arranged in front of the inner layer projection screen, and a second projector 5 and a third projector 6 which correspondingly project to the front side and the back side of the middle layer projection screen 2 are respectively arranged above the inner layer projection screen.
In the present invention, the first projector 4, the second projector 5, and the third projector 6 are all near-focus projectors. From this, can install or arrange in the position nearer from corresponding projection curtain, can save installation space, be convenient for hide the installation (can install in roof department, and can not sheltered from the light path easily, can solve because of the people makes a round trip to walk or the locating position of article and shelter from the problem of light path.
