Abstract
The utility model relates to a screen fixation device for rear-projector equipment. The rear-projector equipment comprises a display screen, a lateral board used for surrounding the screen and fixedly connecting with the screen to support it, a projector generating and projecting image to the screen. The fixation device includes a dovetail groove formed along the extending of the thickness direction on the edge of the screen, whose bottom surface inclined form the edge of the screen to the inside along the direction extending form the front surface of the screen to the back surface; and a wedge protuberating from one end of the lateral board connected fixedly with the screen. The shape, size and position of the wedge are fit to the dovetail groove in the edge of the screen, which make the wedge insert to corresponding dovetail groove fixedly connect the screen with the lateral board.
Description
The utility model relates to a kind of screen fixture of rear-projection equipment, particularly can be used for being spliced into the screen fixture of rear-projection equipment of the display unit of video wall.
Rear-projection equipment as shown in Figure 1, it comprises: with display image projection screen 1 thereon; Fixedly connected to support the side plate 2 of screen around screen 1 periphery and with screen; Be used to produce and to the projector 3 of screen projects images.The screen of present rear-projection equipment adopts side super thin metal frame fixed form, the straight wedge in side and side plate riveted and fixed mode and side ladder metal edge frame technique for fixing etc. more, after the rear-projection equipment of these screen fixed forms is spliced into video wall, between display unit and display unit, leave the frame of not imaging, can not realize the seamless spliced and ultra-fine seam splicing of video wall, simultaneously these screen fixed forms also exist back projected picture had slightly and block, and weakness such as bonding strength is low.
The purpose of this utility model provides a kind of rear-projection device screen fixture, makes screen not have the optics frame, and the whole front surface of display screen all can the Display projector picture.
For achieving the above object, the utility model provides a kind of rear-projection device screen fixture, and this rear-projection equipment comprises: display screen; Fixedly connected to support the side plate of screen around the screen periphery and with screen; Be used to produce and to the projector of screen projects images.Wherein, this fixture comprises: the dovetail groove that extends to form along thickness direction at the edge of this screen, and the bottom surface of this dovetail groove is tilted to the screen inboard by screen edge on the direction of back along the front from screen; From the voussoir that the distal process of fixedlying connected with screen of side plate stretches out, that this voussoir has is corresponding with the dovetail groove of screen edge, make it can insert corresponding dovetail groove and shape, size and location that screen is fixedlyed connected with side plate.
The advantage of fixture of the present utility model is, use the display screen of the rear-projection equipment of fixture of the present utility model not have the optics frame, the whole front surface of display screen is energy Display projector picture all, screen and side plate bonding strength height, ageing-resistant, be widely used in the splicing of large scale display unit video wall, can realize seamless spliced.
From becoming clearer to the description of preferred embodiment of the present utility model feature of the present utility model, advantage, in the accompanying drawing below with reference to accompanying drawing:
Fig. 1 is the structural representation of rear-projection equipment;
Fig. 2 is the view from the screen of observing later of the present utility model of screen;
Fig. 3 is the vertical view of screen of the present utility model, and promptly B is to view;
Fig. 4 is the cutaway view of screen of the present utility model along the C-C direction of Fig. 2;
Fig. 5 is the schematic diagram of the rear-projection equipment of employing screen fixture of the present utility model.
Following with reference to description of drawings preferred embodiment of the present utility model.
Fig. 2 is the back from the screen of rear-projection equipment, i.e. the opposite direction of the A direction among Fig. 1, the view of the screen of observation; Fig. 3 is the vertical view of screen of the present utility model, and promptly B is to view; Fig. 4 is the cutaway view of screen of the present utility model along the C-C direction of Fig. 2; Fig. 5 is the schematic diagram of the rear-projection equipment of employing screen fixture of the present utility model.
The edge that the fixture of the screen 1 of this rear-projection equipment is included in this screen is that A is to the dovetail groove 5 that extends to form along thickness direction, the bottom surface 6 of this dovetail groove 5 is along being tilted to screen is inboard by screen edge from the front of screen to the direction of back (be A to), thereby this bottom surface 6 forms an inside inclination angle beta with screen edge.The width of this dovetail groove bottom surface 6 can be constant, also can be as shown in the figure, along A to diminishing, i.e. d1＞d2; Or along A to becoming big, i.e. d1＜d2.The shape of concrete dovetail groove 5, width size, bottom surface gradient and quantity can be decided according to the parameters such as position of concrete requirement of strength, screen size, projector.
The fixture of the screen 1 of this rear-projection equipment also comprises the voussoir that stretches out from an end 7 of fixedlying connected with screen 1 of side plate 2, the dovetail groove 5 of the shape of this voussoir, size and location and screen edge is corresponding, make it can insert in the corresponding dovetail groove, thereby screen is fixedlyed connected with side plate, as shown in Figure 5.Can be bonding firmly between screen and the side plate by bonding agent, the selection of bonding agent should be according to different selection of material of screen and side plate.Side plate can be metal or nonmetallic materials.
Fig. 5 is the schematic diagram of the rear-projection equipment of employing screen fixture of the present utility model.Wherein, preferably make the inside angle of inclination beta in the bottom surface 6 of dovetail groove 5, the rear-projection picture is all arranged to guarantee whole screen front smaller or equal to half of the projectional angle α of projector 3.Use the display screen of the rear-projection equipment of fixture of the present utility model not have the optics frame, the whole front of display screen is energy Display projector picture all, and screen and side plate bonding strength height are ageing-resistant, be widely used in the splicing of large scale display unit video wall, can realize seamless spliced.
In the device of the present utility model, screen thickness can be 1 millimeter-50 millimeters, and preferred 1 millimeter-30 millimeters, more preferably 1 millimeter-10 millimeters; Side plate thickness can be 1 millimeter-50 millimeters, and preferred 1 millimeter-30 millimeters, more preferably 1 millimeter-10 millimeters; The width of dovetail groove position in front can be 2 millimeters-1500 millimeters; The inclination angle beta of bottom surface can be 10 °-80 °.
In a preferred embodiment of the present utility model, screen is a high-molecular organic material, and thickness is 6 millimeters, and length is 2245.9 millimeters, and width is 1684.4 millimeters; Side plate is a high-molecular organic material, and thickness is 6 millimeters; The width of dovetail groove is 60 millimeters, and its bottom surface gradient is 45 °; During this embodiment adopted short-focus lens projector rear projection, all screens can the Display projector picture, does not have any optics frame and blocks.
