Abstract

The utility model is a large screen projection unit structure which consists of a screen, a frame and a projector, the frame is arranged behind the screen, a reflection mirror coordinating with the projector is arranged in the frame in inclination, which reduces the thickness of the projection unit, at the same time, the projector of the upper unit can be embedded into the lower unit to make full use of the space, the units can be connected into a projection wall with any size at will, so the installation and disassembly are convenient. The screen has a four-layer structure which benefits the develop towards the direction of bigger screen.

Description

The large screen projection unit structure

The utility model is a kind of large screen projection unit structure.

Along with the arrival of information age and the fast development of Computer Multimedia Technology and network technology, projector more and more is subjected to people's favor with its large screen display, and the projecting cell of several independent is combined and obtained big picture, multicolour, high brightness, high-resolution display effect.The large screen projection unit structure is to be made of screen and projector, since projector be with the picture direct irradiation on screen, this just requires between projector and the screen sufficiently long distance to be arranged, make the integral body of projector be laterally long cuboid, the thickness of projecting cell is bigger, and institute takes up space big, install, dismantle very inconvenient, simultaneously, because the restriction of screen mounting structure has influenced the development that screen maximizes.

The purpose of this utility model is to provide the large screen projection unit structure of the effectively reduced product thickness of a kind of simple in structure, installation, convenient disassembly.

The utility model is achieved in that a kind of large screen projection unit structure, is made of screen, frame and projector, and frame is arranged at the behind of screen, is tiltedly installed with the catoptron with projector's cooperating in the frame.

Described projector can be in the below of catoptron.

The upper rear end of described frame can be the splicing breach with the combined splicing of projector of other projecting cell, and the longitudinal cross-section on this splicing breach surface is made up of vertical line segment, oblique line section and horizontal line section.

Described catoptron can be fixed in by fixture on the inclined-plane inwall of splicing breach of frame.

Inclined-plane with the combined splicing of splicing breach of frame also can be arranged at the bottom of described projector front end.

Described screen also can be four-layer structure and constitutes, and the ground floor of outside is the blackstreak curtain, and the second layer is a back-up coat, and the 3rd layer is Fei Nieer lens curtains, and the 4th layer is back-up coat, and it is bonding to learn resin glue by full impregnated Mingguang City between each layer.

The utility model is owing to set up catoptron in frame, shortened the distance between projector and the screen, reduced the thickness of projecting cell, make the rear-projection TV wall that combines take up room little, installation, convenient disassembly, simultaneously, the screen that sandwich construction is formed can make bigger that its size does, and helps developing towards the direction of giant-screen more.

Below in conjunction with embodiment the utility model is described in detail:

Fig. 1 is the front elevation of large screen projection unit structure;

Fig. 2 is the side view of large screen projection unit structure;

Fig. 3 is the rear view of large screen projection unit structure;

Fig. 4 is the front view of the rear-projection TV wall of four projecting cells compositions;

Fig. 5 is the side view of the rear-projection TV wall of four projecting cells compositions;

Fig. 6 is the front elevation of screen;

Fig. 7 is the side view of screen;

Fig. 8 is the rear view of screen.

With reference to figure 1-Fig. 8, the large screen projection unit structure is made of screen 1, frame 2 and projector 3, frame 2 is arranged at the behind of screen 1, be tiltedly installed with catoptron 4 in the frame 1 with projector's 3 cooperatings, can effectively shorten the distance between projector 3 and the screen 1 like this, reduce the thickness of projecting cell, dwindled the occupation of land space of the video wall after the combination.

Projector 3 is arranged at the below of catoptron 4, help the combined and spliced mutually of projecting cell, combined and spliced between for convenience adjacent projecting cell mid frame and the projector, the upper rear end of frame 2 is the splicing breach 5 with the combined splicing of projector of other projecting cell, the longitudinal cross-section on these splicing breach 5 surfaces is by vertical line segment 6, oblique line section 7 and horizontal line section 8 are formed, corresponding, inclined-plane 9 with the splicing breach 5 combined splicings of frame 2 is arranged at the bottom of projector's 3 front ends, the projector of a last unit can embed in the splicing breach 5 of frame rear end of next unit, made full use of the space, can splice arbitrarily and form the projection wall of any size.For the ease of installing, catoptron 4 is fixed in by fixture on the inclined-plane inwall of splicing breach 5 of frame 2, for install, convenient disassembly, drawer type is made by projector 3, be provided with guide groove 10,11 in the both sides of frame 2, the both sides relative set guide rail 12,13 of projector 3, the projecting cell or pull down of can at short notice projector 3 being packed into fast from projecting cell, care and maintenance is easy, rapid.

For screen 1 is done more, screen 1 constitutes for four-layer structure, and the ground floor of outside is the blackstreak curtain, and the second layer is a back-up coat, and the 3rd layer is Fei Nieer lens curtains, and the 4th layer is back-up coat, and it is bonding to learn resin glue by full impregnated Mingguang City between each layer.Screen 1 is fixing by frame 15, and frame 15 is fixed on the frame 2 by the fixed mount 14 of correspondence.
