Technical field
The utility model relates to a kind of rear-projection machine, and the framed structure that is specifically related to the assembly type rear-projection case of rear-projection case and can hangs the projection screen and the cabinet cover plate of installation is guaranteed the flatness of projection screen and the safety of the interior equipment of cabinet.
Background technology
Along with the rapid growth of social informatization, the visual demand of information also sharply increases.Particularly in some electronic teaching, Web conference is commanded in Surveillance center, commercial exhibitions and the home theater,, the application of large screen back projection system is more and more widely.The rear-projection case is the chief component in the large screen back projection system, also is the necessary carrier of screen, projector, reflecting system etc., is essential and utilization rate is high, use a kind of very widely device in the large screen back projection field.
Because the market differentiation and the diversification of demand, by the many kinds of specifications and models that have of the large screen back projection system of the screen combination of various different projectors, different specification size.A rear-projection case of corresponding each screen specification size design; Simultaneously, also need to consider the problem of the multiple rear-projection case of the influence that application the brought specification of compatible different projectors.The most frequently used screen specification size just has 50 cun, 60 cun, 67 cun, 70 cun, 80 cun, 84 cun and 96 cun etc., and existing rear-projection box structure also cannot satisfy simple and easy, smooth, the indeformable installation requirements to these different specification size screens.In the existing method, must be equipped with the corresponding specification size rear-projection case of respective numbers, expend ample resources and design and make the rear-projection case that is fit to the different specification size screen.
At present, the back projection type projection screen of different substrate materials manufacturing all exists temperature, the humidity because of environment to change the phenomenon that expands or shrink, if screen is completely fixed on the rear-projection case, and the rear-projection case is because its rigid structure is not yielding, therefore screen can not freely stretch and produce irregular external drum, when producing hooking being subjected to external environment influence like this, the rear-projection character projection is known from experience problems such as producing, picture distortion unclear such as screen imaging because focal length is inaccurate.
Therefore, provide a kind of and satisfy the rear-projection case that the various sizes needs are convenient to assemble, and guarantee that a kind of rear-projection case of screen integral smoothness, elimination hooking, assurance imaging effect, raising display resolution is necessity in fact.
Summary of the invention
The utility model purpose provides a kind of rear-projection case that satisfies the various sizes needs, uses framed structure, is convenient to assemble, and this rear-projection case is guaranteed the safe operation of screen integral smoothness and rear-projection equipment.
In order to realize the purpose of this utility model, the special framed structure that proposes a kind of rear-projection case is characterized in that, described rear-projection case is assembled by two kinds of framed structures, and wherein, a kind of framework is for installing the framework of screen (3), be positioned at rear-projection case front upper place, constitute by section bar (2); Another kind of framework uses coupling arrangement to form by section bar (1), and described screen (3) is installed at the framework inner suspension that section bar (2) constitutes by suspender, and described panel (7) covers the framework of section bar (1) assembling.
A face of described section bar (2) is baffle plate (8), and described baffle plate (8) extends forward, and the extension has an angle of inclination downwards, the slot (4) for connecting in the middle of 3 faces of other of described section bar (2); Described suspender comprises spring (6) and suspension member (5); Wherein, described suspension member (5) inserts a slot (4) of below, baffle plate (8) extension, described screen (3) is connected with suspension member (5) by described spring (6), the framework that 4 limits of described screen (3) use a plurality of suspenders and section bar (2) to form is connected, and makes Floating the hanging in the said frame of screen (3).
On two mutual vertical planes of described section bar (1), near the drift angle place panel slot (9) is being set respectively, described two panel slots (9) are provided with in vertical direction, between the panel slot (9) of adjacent two section bars 1 of framework, insert panel (7), use described panel (7) that the framework that described section bar (1) constitutes is coated.
The framed structure of rear-projection case of the present utility model, adopt the modular design of two kinds of section bars, the demand that can adapt to the specification of different rear-projection casees, assembling mode is flexible, save artificial and material cost, especially the suspension of screen is installed, and guarantees the screen integral smoothness, and the plug-in type panel is easy for installation.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further described below in conjunction with specific embodiment and conjunction with figs..
Fig. 1 is the utility model assembly type rear-projection case front view; Whole rear-projection case comprises two parts framed structure up and down, is combined by section bar 1 and 2 two kinds of section bars of section bar.Frame is combined by section bar 2 before the frame superstructure, is used to install screen 3.Lower frame is the supporting construction of rear-projection case, is formed by connecting by section bar 1.
Fig. 2 is a rear-projection case back side mounting structure synoptic diagram; As shown in the figure, except the upper frame of suspension screen 3 shown in Figure 1, other part frames combine by section bar 1, its interconnective mode adopts web member, and web member is fastening with nut, makes two section bars 1 be vertical connection mutually, be combined into case after-frame, side frame at last respectively, top frame etc.
Fig. 3 is a rear-projection case screen mounting structure synoptic diagram; Screen 3 is installed in the upper frame of whole rear-projection case by section bar 2 combinations by suspender, and suspender is as follows by the view specification that amplifies: a face of section bar 2 is a baffle plate 8, and baffle plate 8 protracts and an angle of inclination is arranged downwards; Slot 4 for connecting in the middle of 3 faces of other of section bar 2.When the combination upper frame, the baffle plate 8 of section bar 2 is all stretched in framework, as shown in drawings, suspension member 5 of insertion below baffle plate 8 extensions, screen 3 is connected with suspension member 5 by spring 6,4 limits of screen 3 use a plurality of springs 6 to be connected with a plurality of suspension members 5, screen 3 is hung be installed in the upper frame.
