Abstract
The utility model relates to a screen hanging system of a rear-projection all-in-one machine, which comprises a frame, a screen and a screen hanging device, wherein the frame consists of sections (2) which are assembled together, the hanging device is a suspended hanging device and the screen (3) is installed in the inner frame of the frame through the screen hanging device in a suspended way. The screen hanging system has the advantages that the assembling method is flexible and convenient, labor and material costs are saved, and especially by adopting the suspended installation method of the screen, the overall flatness of the screen is ensured, the screen deformation is eliminated, the imaging effect is ensured and the display definition is improved.
Description
Technical field
The utility model relates to a kind of rear-projection machine, is specifically related to the screen suspension of rear-projection all-in-one, thereby the flatness of guaranteeing projection screen improves the display image sharpness.
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, and the application of large screen back projection system more and more widely.The rear-projection case of rear-projection all-in-one 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.
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, problems such as when producing hooking being subjected to external environment influence like this, that the rear-projection optical projection system can produce because focal length is inaccurate is unclear such as screen imaging, picture distortion.
Therefore, provide a kind of and guarantee that a kind of rear-projection all-in-one screen suspender 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 all-in-one screen suspension, big specification screen is suspended be installed in rear-projection all-in-one cabinet, guarantees the screen integral smoothness, effectively prevents hooking.
In order to realize the purpose of this utility model, the spy puies forward a kind of screen suspension of rear-projection all-in-one, this screen suspension comprises framework, screen and screen suspender, described framework is assembled by section bar 2, described suspender is floated suspender, and described screen 3 is by among the floated inside casing that is installed in described framework of described screen suspender.
Described section bar 2 is that a kind of cross section is substantially square section bar, is the slot 4 that connects vertically in the middle of 4 faces of described section bar 2; Described suspender comprises spring 6 and suspension member 5, and described suspension member 5 front ends are provided with a hanging hole 8; Described suspension member 5 inserts in the described slot 4, the hanging hole 8 of suspension member 5 front ends stretches out slot 4,6 one edges that hang over described screen 3 of described spring, collude on the hanging hole 8 of described suspension member 5 other end, 4 limits of described screen 3 use a plurality of suspenders to be connected with section bar 2, make screen 3 Floating hanging in the described framework.
A face is provided with baffle plate 7 in 4 surfaces of described section bar 2, baffle plate 7 from this surface of section bar 2 to protracting and its extension has an angle of inclination downwards; When group frame, extend in described framework in the direction parallel with described screen 3 extension of this baffle plate 7, covers described spring 6 and suspension member 5.
Rear-projection all-in-one screen suspension of the present utility model, adopt the modular design of section bar, assembling mode is flexible, and especially the suspension of screen is installed, and guarantees the screen integral smoothness, eliminates hooking, guarantees imaging effect, improves display resolution.

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 all-in-one front view; Whole rear-projection all-in-one 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, and 4 nodal pattern materials 2 interconnect, and forms anterior upper frame at last, is used to install screen 3.
Fig. 2 is a rear-projection all-in-one screen mounting structure synoptic diagram; Screen 3 passes through suspender, be installed in the upper frame of whole rear-projection all-in-one by section bar 2 combinations, suspender is as follows by the view specification that amplifies: section bar 2 is that a kind of cross section is substantially square a kind of section bar, one of them face is provided with baffle plate 7, baffle plate 7 from the surface of section bar 2 to protracting and its extension has an angle of inclination downwards; Be the slot 4 that connects vertically in the middle of 3 faces of other of section bar 2.
Behind the combination upper frame, all stretch to inherent parallel with the screen direction of framework the extension of the baffle plate 7 of section bar 2, as shown in drawings, inserts a suspension member 5 in the slot 4 below baffle plate 7 extensions, and suspension member 5 front ends are provided with a hanging hole 8, stretch out slot 4; 6 one edges that hang over screen 3 of spring, other end collude on the hanging hole 8 of suspension member 5, and 4 limits of screen 3 use a plurality of hanging holes 8 to be connected with section bar 2, make in the Floating preceding frame that hangs over upper frame of screen 3.
Be given a shock, or framework and screen 3 deform, because suspension structure is adopted in being connected of screen 3 and framework, distortion that can the issuable thus screen 3 of balance has guaranteed the flatness of screen 3.
With preferred embodiment openly as above they are not to be used for limiting the utility model though the utility model is own, and the content that protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.Anyly have the knack of present technique field person, in not breaking away from spirit and scope of the present utility model, various variations of being done or be equal to replacement all should belong to protection domain of the present utility model.
