Abstract
An embedded projection screen self-adaption frame relates to the technical field of large size projection screen installation frames, and comprises a support frame used for fixing a projection screen. The support frame is provided with an installation cavity, one side of the installation cavity is open, and a plurality of elastic assemblies used for connecting the projection screen and the support frame are arranged in the installation cavity. By means of the embedded projection screen self-adaption frame, concave-convex deformation, cracking and the like of a rear projection screen of the projection screen caused by environmental and climatic changes are removed, phenomena of local blurring and deformation of images of the projection screen caused by deforming and uneven screen are fundamentally avoided, display quality of the images of the projection screen is improved, and combination of the projection screen and the support frame is attractive simultaneously.
Description
Technical field
The utility model relates to large-size projecting screen installation frame technical field, particularly a kind of embedded projection screen self-adaptation framework.
Background technology
Along with science and technology development, the especially develop rapidly of computer technology and mechanics of communication, large screen display receives liking of people all the more.In recent years, in shadow casting technique constantly in the development, image can be shown through the image border integration technology and to accomplish very greatly that the one-time formed large-scale projection screen of the thing followed seems particularly important.In the prior art at present, large-size projecting screen is generally fixed with two kinds of methods: first kind is the rivet method, and promptly punching directly is fixed on the framework with rivet in position, screen edge; Though this method is simple; But second-rate, can not solve the phenomenon that screen expands with heat and contract with cold, and arrive winter temperature low the time; The situation of breaking is arranged, and the loss that causes is bigger; Second method is to clamp with two planks before and after the screen; The phenomenon that the screen of having avoided direct punching to cause like this breaks is a method commonly used at present, but in actual use; Can cause equally the phenomenon of rising-heat contracting-cold because of environment and variation of temperature; Cause anamorphose with fuzzy, greatly reduce the quality of screen display, influence visual effect.
The utility model content
The utility model purpose is in order to overcome above-mentioned deficiency, to provide a kind of and can effectively prevent the projection screen distortion, self-adaptation projection screen expansion coefficient, thereby the projection screen self-adaptation framework of raising image displaying quality.
For solving the problems of the technologies described above; The technical scheme of the utility model is: embedded projection screen self-adaptation framework; Comprise the support frame that is used for fixing projection screen; Said support frame has the installation cavity, and a side of said installation cavity is uncovered, is provided with some elastic partss that are used to connect projection screen and support frame in the said installation cavity.
As further improvement, said elastic parts comprises that an end is fixedly installed in the securing member on the said support frame, and the other end of said securing member is connected with the extension spring that is used to connect projection screen.
The beneficial effect of the utility model is: the utility model is provided with elastic parts and fixes projection screen on support frame; The extension spring that is provided with on the elastic parts can be regulated according to the expansion coefficient of projection screen automatically; Thereby solved rear projection screen deformation of unevenness that projection screen causes because of environment and climate change, broken etc.; Fundamentally solve the phenomenon of the smudgy distortion of projection screen image local that causes owing to the hooking injustice, thereby improved the display quality of projection screen image; The utility model is enclosed in the connecting portion of elastic parts and elastic parts and projection screen in the support frame, makes that the projection screen integral body after the installation seems more elegant in appearance.
Description of drawings
Accompanying drawing is the structural representation of the utility model;
Among the figure: 1, projection screen, 20, extension spring, 21, securing member, 3, support frame.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.
Shown in accompanying drawing; A kind of embedded projection screen self-adaptation framework; Comprise the support frame 3 that is used for fixing projection screen 1; Said support frame 3 has the installation cavity, and a side of said installation cavity is uncovered, is provided with some elastic partss that are used to connect projection screen 1 and support frame 3 in the said installation cavity.Said elastic parts comprises that an end is fixedly installed in the securing member 21 on the said support frame 3, and the other end of said securing member 21 is connected with the extension spring 20 that is used to connect projection screen 1.
The cross section of support frame 3 is the rectangle of an end opening; And the width of openend is less than the width of non-openend, and support frame 3 inside are provided with the dividing plate that is used for fixing elastic parts, and securing member 21 1 ends of elastic parts are fixed on the dividing plate; The other end of securing member 21 connects extension spring 20; Extension spring 20 1 ends are provided with the hook that is used to connect projection screen 1, and the position that elastic parts and elastic parts are connected with projection screen 1 all is positioned at support frame 3 inside, and elastic parts is evenly distributed on support frame 3 inside.
The utility model purpose method of application is; With the punching of projection screen 1 periphery, be fixed on the support frame 3 with a plurality of elastic partss, extension spring 20 is the hole that an end of hook shape passes on the projection screen 1 and is connected with projection screen 1, then securing member 21 is fixed on the dividing plate of support frame 3.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
Claims (2)
1. embedded projection screen self-adaptation framework; Comprise the support frame that is used for fixing projection screen; It is characterized in that: said support frame has the installation cavity, and a side of said installation cavity is uncovered, is provided with some elastic partss that are used to connect projection screen and support frame in the said installation cavity.
2. embedded projection screen self-adaptation framework according to claim 1 is characterized in that: said elastic parts comprises that an end is fixedly installed in the securing member on the said support frame, and the other end of said securing member is connected with the extension spring that is used to connect projection screen.
