Description
Technical field
The utility model relates to projection screen field, more precisely, relates to the anti-light projection screen of a kind of backlight.
Background technology
Projection screen of the prior art, its complex structure, cause its heavier-weight, cost is high, and processing is comparatively complicated, exquisite not.In prior art, projection screen does not have background light, and long-time viewing easily causes eye fatigue, and curtain face does not have the function of environment resistant light, and during projection, surround lighting causes projected picture fuzzy.
Utility model content
The utility model, in order to solve problems of the prior art, provides the anti-light projection screen of a kind of backlight.
In order to realize above-mentioned object, the technical solution of the utility model is: the anti-light projection screen of a kind of backlight, comprise environment resistant light curtain face, also comprise and to be positioned at above environment resistant light curtain face and to surround the frame of framework, adjacent two frames are fixed by iron turning, the edge in described environment resistant light curtain face turns down the upper end to frame from the lower end of frame, and the edge curl in environment resistant light curtain face becomes sleeve, string bar is had in described sleeve inner sleeve, also comprise multiple first extension springs along the distribution of string bar length direction, one end of described first extension spring is connected on frame, the other end is hooked on string bar, also be provided with face-piece in the outside of described frame, described face-piece is provided with LED.
Preferably, described environment resistant light curtain face edge curl and hot melt or sewing become sleeve.
Preferably, described frame is provided with the draw-in groove for engaging one end, iron turning.
Preferably, described iron turning is screwed on frame.
Preferably, described face-piece one end is provided with the first coupler body being hooked in frame edge, and the other end is provided with the second coupler body, is also provided with the second extension spring, and one end of described second extension spring is hooked in the second coupler body, and the other end is hooked on frame.
The anti-light projection screen of backlight of the present utility model, comprises frame, environment resistant light curtain face, string bar, extension spring, face-piece, LED etc., by the ingenious cooperation of said structure, thus makes the anti-light projection screen structure of backlight simple, lightweight, and with low cost.
Accompanying drawing explanation
Fig. 1 shows the partial schematic diagram of the anti-light projection screen of the utility model backlight.
Embodiment
The technical matters solved to make the utility model, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further embodiment of the present utility model.
The utility model provides the anti-light projection screen of a kind of backlight, and it comprises environment resistant light curtain face 1, and environment resistant light curtain face 1 is existing technology, no longer illustrates at this.Also comprise and to be positioned at above environment resistant light curtain face 1 and to surround the frame 3 of framework, for rectangular projection screen, frame 3 is provided with four, and adjacent two frames 3 are fixed together by pasting iron turning 2, thus make four frames 3 define the framework of a rectangle.Iron turning 2 can directly be fixed on frame 3, the utility model one preferred embodiment in, described frame 3 is provided with draw-in groove, is used for holding iron turning 2, thus iron turning 2 can be stashed.Iron turning 2 and frame 3 can be fixed by screw.
Environment resistant light curtain face 1 is positioned at the below of frame 3, and its edge is from the turnover of the lower end of frame 3 to the upper end of frame 3, and the edge curl in environment resistant light curtain face becomes sleeve 5, such as, its edge can curling after fix by the mode of hot melt or sewing, form sleeve 5.String bar 4 is had in described sleeve 5 inner sleeve, also comprise multiple first extension springs 8 along the distribution of string bar 4 length direction, one end of described first extension spring 8 is connected on frame 3, and the other end is hooked on string bar 4, thus is fixed on frame by the border elastic in environment resistant light curtain face 1.Particularly, one end of the first extension spring 8 needs through the aperture that curtain face is arranged, and is hooked on string bar 4.Also be provided with face-piece 7 in the outside of described frame 3, described face-piece 7 is provided with LED 6.
The anti-light projection screen of backlight of the present utility model, comprises frame, environment resistant light curtain face, string bar, extension spring, iron turning, LED etc., by the ingenious cooperation of said structure, thus makes back-lit projection shield structure simply, lightweight, and with low cost.
Face-piece 7 of the present utility model is fixed on the outside of frame 3 by mode well-known to those skilled in the art, the utility model one preferred embodiment in, described face-piece 7 one end is provided with the first coupler body 9 being hooked in frame 3 edge, the other end is provided with the second coupler body 10, also be provided with the second extension spring 11, one end of described second extension spring 11 is hooked in the second coupler body 10, and the other end is hooked on frame 3, thus achieves the fixing of face-piece 7 and frame 3.Wherein, the first coupler body 9, second coupler body 10 can be the bending at face-piece edge.
The utility model is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each embodiment with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of applicant has all dropped in scope that the utility model claim protects.
