Abstract
The utility model discloses a projecting case body, relating to a projecting case body of the back projection screen, which is also used to make the combination case body of the large-scale projection screen of the patching wall system, wherein a rectangular frame construction is formed by the connection of the aluminum section bar through a die casting aluminum corner, and the periphery of the frame is all sealed by an aluminum alloy plate; the front end of the top of the rectangular frame is provided with a protruding edge; the aluminum alloy plate is connected with the protruding edge and transited to the middle position of the top, which forms an inclined surface for fixing a reflector; the upper, the left and the right sides of the frame are equipped with screen pothooks; and the periphery of the frame is provided with a plurality of installing screw holes, and at the same time matched with installing screw rods. The projecting case body has strong rigidity, high intensity, light weight and beautiful shape and is unable to deform, the screen installing can carry on the multi-directional regulation, and the patchwork of the screen is small. The reflector can carry on the multipoint regulation and guarantee the integrity of the image and the non-linear distortion, and the regulation is convenient and accurate. The utility model can be widely applicable for the back projection and the patching wall system.
Description
Technical field
The utility model relates to a kind of Projection box of rear projection screen, and this Projection box can also be used to make the combination box of piecing together the large-scale projection screen of wall system.
Background technology
Projection box is the apparatus and equipment that is used for fixing projector equipment, and these instruments comprise: screen, catoptron, projector and six-axial adjustment frame etc., Projection box also works to block stray light.There are a lot of defectives in existing Projection box.Casing is thicker, it is big to take up room, piece together behind the wall because the measurements of the chest, waist and hips position of each screen and be difficult to regulate, the surface smoothness of display wall is relatively poor, and whole structure is difficult to be transferred to the best, be difficult to be combined into curved wall, and dismounting inconvenience, installation period is long, and it is big to piece together the wall construction piece, and structural stability is poor, and it is attractive in appearance that profile is owed.At present, do not have Projection box preferably, obtain being extensive use of preferably in piecing together wall system, the piece precision of its casing is difficult to reach, the drop shadow effect of influence image, and use inconvenience, more not attractive in appearance.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Projection box, and this Projection box is handsome in appearance, makes exquisiteness, splicing precision height, and the intensity height of casing, good rigidly, not yielding, in light weight, each screen can multi-directionly be adjusted behind the assembly wall.
In order to achieve the above object, the utility model provides following technical scheme, a kind of Projection box, constitute the rectangular parallelepiped framed structure by aluminium section bar by the binding of die casting aluminium angle, front end forms raised brim above the rectangular parallelepiped framework, aluminium alloy plate connection bump edge is to the transition of crown center position, be formed for the inclined-plane of stationary mirror, both sides, rectangular parallelepiped framework lower end are provided with the support footing, the both sides of rectangular parallelepiped framework, rear side, the support footing of top and both sides is all used the aluminium alloy plate involution, on the framework, a left side, right edge is equipped with the screen hook, be provided with a plurality of installation screws around the framework, simultaneously the supporting installation screw rod that is provided with.
The obvious advantage of this Projection box is, its aluminum alloy frame adds the syndeton of aluminium alloy plate, has guaranteed the rigidity and the intensity of casing, can not be out of shape, in light weight, handsome in appearance, simultaneously, its screen hook and each are installed the setting of screw, be convenient to multi-direction adjustment to screen, the piece that guarantees screen is limited in certain scope, can reach piece less than 0.3mm, and the unevenness between screen and the screen can be less than 0.2mm.The installation screw rod that is used for fixing the inclined-plane of catoptron and matches, the multiple spot of being convenient to catoptron is regulated, and guarantees that visual complete sum do not have linear distortion, and is easy to adjust, accurate.

Embodiment
As shown in Figure 1, a kind of Projection box 7, constitute the rectangular parallelepiped framed structure by aluminium section bar by 1 binding of die casting aluminium angle, front end forms raised brim 2 above the rectangular parallelepiped framework, aluminium alloy plate connection bump edge is to the transition of crown center position, be formed for the inclined-plane 3 of stationary mirror, both sides, rectangular parallelepiped framework lower end are provided with supports footing 4, the both sides of rectangular parallelepiped framework, rear side, the support footing of top and both sides, all use the aluminium alloy plate involution, on the framework, a left side, right edge is equipped with screen hook 5, is provided with a plurality of installation screws 6 around the framework, simultaneously the supporting installation screw rod that is provided with.
When reality was used, screen 8 was fixed on the front end of projection case, and projector 9 is placed in the bottom of casing, and catoptron 10 is installed on the inclined-plane, and the ray cast that projector 9 sends reflexes on the screen 8 behind catoptron 10, formed image effect.
