Integral type multiple surface assembled large display screen projector
Technical field
The utility model relates to universal apparatus capable of fluctuating, the high-definition image projection of integral type multiple surface assembled large display screen projector, particularly projector, belongs to video performance system regions.
Background technology
Current most of video display technology mostly is LED full-color display, the display of DLP rear-projection large screen splicing, liquid crystal-spliced or plasma panel tiled display etc., and these display system volumes are large and cost is high, all can only demonstrate picture in one side, can not show on four sides.
But for large-scale theater, large-scale auditorium, no matter LED full-color display, DLP rear-projection large-size screen monitors have much, for the spectators in after being sitting in or corner, all there is distance, cannot watch the problem of performance in real time in sports palace.Its large-scale multiaspect display screen is used for the large-scale places such as sports palace, is all to be undertaken by the mode of field fabrication, and cost is high, manufacture difficulty is large, and later maintenance is inconvenient.
Chinese patent literature discloses the patent of the many integration of equipments of multinomial video system, but does not have the technology of the real-time Presentation Function aspect of four sides picture.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, solve in large-scale auditorium after being sitting in or the spectators in corner cannot watch the problem of in real time performance, invent a kind of with the integral type multiple surface assembled large-size screen monitors mould Rear projection device that can meet the comprehensive display that large-scale theater, large-scale auditorium and sports palace audio video synchronization are performed in a radio or TV programme.
The utility model integral type multiple surface assembled large-size screen monitors mould Rear projection device feature is: projection darkroom is made up of the lifting connection bracket (1) on upper strata and the darkroom framework (2) of lower floor, lifting connection bracket (1) is a shaped as frame steel work, multiple lifting supporting point is arranged at lifting connection bracket (1) top, and lifting connection bracket (1) bottom directly connects darkroom framework (2); Four faces of darkroom framework (2) respectively have one piece for the screen frame of back projection type screen installation site (6), and the bottom in projection darkroom is provided with access door, and projection has adjustable bracket of projector in darkroom.
The initial tension of spring that adjustable screen tension force is housed inside described screen frame regulates.
Projection darkroom adopts 1.5mm thickness, 30 × 30mm square tubes soldering forms, and projection darkroom skin arranges Decorative frame, and Decorative frame can select the ornament materials installing various material, the overall combination installation can carrying out a complete set of system at production department in projection darkroom, also can combine installation at the scene.
Projection top chamfer position, darkroom can be installed as the supporting sound system of optical projection system.
Projection darkroom is provided with the load-bearing erection bolt hole that can carry whole darkroom and necessary operating personnel's weight, and projection top, darkroom has installs the installing hole that projector regulates support.
The utility model adopts high strength steel equipment structure, structurally consider lifting or seat dress load carrier, be provided with the tensioning mechanism of adjustable screen installation pretightening force, projector's installing and adjusting mechanism in darkroom, be provided with access hole in bottom, darkroom can be entered from installing port when Installation and Debugging and maintenance, darkroom arranged outside Decorative frame, available multiple material is decorated darkroom.
The utility model integral type multiple surface assembled large-size screen monitors mould Rear projection device delicate structure, cost is low, is convenient to maintenance.Can be widely used in the needs needing to carry out large screen display in the middle of the hall, mounting and adjusting is convenient, convenient relative to the mode of routine feasible, takies less to room.

The top view of Fig. 3 the utility model Fig. 1.
In figure: 1, lift connection bracket; 2, darkroom framework (making of 30 × 30 square tubes solderings); 3, chamfering position; 4, bottom square tube bilayer makes, and can carry 100kg weight; 5, the access door in the middle of bottom; 6, back projection type screen installation site, surrounding arranges pretightning force and regulates; 7, each screen opposite all makes projector's installing and adjusting mechanism.
Detailed description of the invention
Press structure as shown in Figure 1, Figure 2 and Figure 3, first design overall structure according to screen size and make frame structure with 30*30 square tubes soldering, prefastening force adjustment mechanism is made at screen frame, darkroom lifting Connection Block is made according to erecting bed situation, bottom square tube bilayer makes, 100kg weight can be carried, bottom intermediate fabrication access door, each screen opposite all make projector's installing and adjusting mechanism, lift in erecting bed, screen is installed, projector is installed, according to installation environment, extraneous adornment is carried out to darkroom, optical projection system is debugged.
The utility model projection darkroom framework 2 adopts 1.5mm thickness, and 30 × 30mm square tubes soldering forms, and makes 4, can carry 100kg weight bottom darkroom with square tube bilayer; Bottom intermediate fabrication access door 5; Chamfering position 3 can be installed as the supporting sound system of optical projection system; Back projection type screen installation site 6, surrounding arranges pretightning force and regulates; Each screen opposite all makes projector's installing and adjusting mechanism.
The utility model adopts integrated combination, use high strength steel girder construction, built-in display screen tension adjustment mechanism, projector's installing and adjusting mechanism, audio amplifier installing and adjusting mechanism, has enough Problem work, can after factory carries out production combination, install at the scene as finished product, greatly facilitate construction and installation, and saving construction cost cost, improve display precision.
