Description
Technical field
This utility model relates to a kind of rear projection screen, specifically a kind of rear projection hard screen.
Background technology
Because back projection (rear-projection) has, environment resistant light ability is strong, bright in luster, contrast advantages of higher, is widely used in each
The high-end occasions such as class command scheduling center, video conference rooms and exhibition room, conventional rear projection screen is broadly divided into soft by manufacturing material
Curtain and hard curtain two class.Supporting part is to be made by the pvc thin film with dispersion factor, and its advantage is lightweight, conveniently moving, can lead to
Cross high frequency and be welded into super large breadth (height is more than 4.6m), show the most unrestricted；Easily there is breadth when being and use in shortcoming
Fluctuation, affects display effect, poor durability, needs regular maintenance.Hard curtain is to use Merlon (PC) or acrylic (PMMA)
Making, usual thickness is 1 ~ 5mm, can preferably overcome the disadvantages mentioned above existing for supporting part, also has convenient transportation simultaneously and (can roll up
Bent transport) etc. advantage.Current rear projection hard screen generally includes aluminum alloy frame and screen, and screen is arranged in aluminum alloy frame.
But the installation between existing aluminum alloy frame is the most firm and firm.
Summary of the invention
The technical problems to be solved in the utility model is to provide easily installation, and stabilized structure is reliable, and screen focusing is good
Rear projection hard screen.
In order to solve above-mentioned technical problem, this utility model takes below scheme:
A kind of rear projection hard screen, including being enclosed the framework constituted and the screen being arranged in this framework by four aluminum alloy frames
Curtain, is connected by corner brace between described adjacent aluminum alloy frame, aluminum alloy frame is equiped with screw drag hook, on this screw drag hook
End locking has nut, and screen is hooked in this screw drag hook lower end.
Being provided with rail groove in described aluminum alloy frame, be provided with slide block in this rail groove, this slide block one end is actively installed on track
Groove is interior, the other end stretches out rail groove, and screw drag hook passes this slide block.
It is set with pad on described screw drag hook.
Described pad is spring shim.
Corner brace slot it is provided with in described aluminum alloy frame.
Described screen includes diffuse-reflectance layer, light-absorption layer and the imaging basic unit being sticked successively.
Base material in described imaging basic unit is resin base material.
This utility model stabilized structure is firm, is difficult to loosen, it is ensured that normally use, and by the improvement to screen, makes
The focusing of screen is more preferable, reduces light losing.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model main TV structure schematic diagram；
Accompanying drawing 2 is this utility model cross-sectional view；
Connection diagram is installed in the local of adjacent two aluminum alloy frames of accompanying drawing 3 this utility model；
Accompanying drawing 4 is this utility model screen cross-sectional view.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.
As shown in accompanying drawing 1～4, this utility model discloses a kind of rear projection hard screen, encloses including by four aluminum alloy frames 1
The framework constituted and the screen 2 being arranged in this framework, connected by corner brace 7 between described adjacent aluminum alloy frame 1, aluminium alloy
Being equiped with screw drag hook 3 on frame 1, this screw drag hook 3 upper end locking has nut 4, and screen 2 is hooked in this screw drag hook 3 lower end, increases
Add tension force.Being provided with corner brace slot 6 in aluminum alloy frame 1, corner brace 7 plug-in mounting enters in this corner brace slot 6, facilitates installation.Pass through angle
Code makes adjacent aluminum alloy frame be firmly installed to link together, easy for installation.
Being provided with rail groove in aluminum alloy frame 1, be provided with slide block 8 in this rail groove, this slide block 8 one end is actively installed on rail groove
Interior, the other end stretches out rail groove, and screw drag hook 3 is through this slide block 8.This slide block can carry out the shifting of certain distance in rail groove
Dynamic, consequently facilitating mounting and adjusting, it is achieved install more accurately.
Pad 5 it is set with on screw drag hook 3.Pad 5 is spring shim.Rub so that can reduce during locking nut
Wipe.
Additionally, screen 2 includes diffuse-reflectance layer 21, light-absorption layer 22 and the imaging basic unit 23 being sticked successively.In imaging basic unit
Base material is resin base material.Diffuse-reflectance layer surface is micro-optic nanometer microparticle structure, plays focussing force, by this diffuse-reflectance
Layer, it is possible to effectively expand the viewing visual angle of screen.Light-absorption layer can absorb projected light, and surface processes for projection coating, reduces light
Line loss is lost.
In this utility model, facilitated by corner brace and two adjacent aluminum alloy frames installations are linked together, and
Utilize screw drag hook that screen is hooked, increase tension force, utilize nut and spring shim reduce friction and realize more firm
Install.By the improvement to screen, enable screen to expand viewing visual angle, and reduce light losing, improve the quality of screen.
It should be noted that the above is not to restriction of the present utility model, without departing from wound of the present utility model
On the premise of making design, any obvious replacement is all within protection domain of the present utility model.
