Technical solution of the present invention is equipped with air port 116 by using an at least frame for the frame body 110 of display screen fixture 100
Scheme, while accommodating cavity for accommodating display screen 200 is equipped in frame body 110, accommodating cavity is connected to air port 116, in this way, working as
Cooling fan from the side of display screen 200 to display screen 200 dry when, blower rotate the cooling air-flow to be formed can directly into
Enter to by air port 116 and enter in accommodating cavity, and then realizes that cooling air-flow is applied directly to display screen 200, therefore can have
Effect takes away the heat generated when display screen 200 works, radiates convenient for display screen 200.
Further, as shown in figure 4, frame body 110 includes the first shell 111 and second shell 112 that are oppositely arranged, first
Air port 116 is formed between shell 111 and second shell 112.So set, display screen 200 can be fixed on first shell 111 with
Between second shell 112, while being also convenient for the processing of frame body 110.In practical applications, frame body 110 can also be using one
Structure, and display screen 200 can also be fixedly arranged in accommodating cavity by the way of cementing or grafting.In the present embodiment, first shell
Body 111 and second shell 112 are arranged in tabular, wherein a surface of first shell 111 towards second shell 112 is equipped with
First groove of the both side surface opposite through the first shell 111, therefore, first shell 111 is in first groove and
Two shells 112, which enclose, to be set to form accommodating cavity.Either second shell 112 towards a surface of first shell 111 be equipped with through this
Second groove of the opposite both side surface of two shells 112, therefore, second shell 112 is in second groove and first shell 111
It encloses and sets to form accommodating cavity.Certainly, first shell 111 and/or second shell 112 may be alternatively provided as the structure of arc fold bending.
For the ease of overhauling and clearing up display screen 200, in the embodiment of the application, first shell 111 and second shell
Body 112 is detachably connected.When needing to overhaul or clearing up display screen 200, first shell 111 and second shell 112 are dismantled, is made
Display screen 200 appears, and can carry out subsequent work.
In the present embodiment, one of them is equipped with buckle 111a for first shell 111 and second shell 112, wherein another set
There is the card slot 112a with buckle 111a cooperation.As shown in Figure 3 and Figure 4, first shell 111 and second shell 112 are rectangle knot
Structure, the opposite sides of first shell 111 are equipped with buckle 111a, and the opposite sides of second shell 112 is equipped with card slot 112a, buckle
111a is set to the edge of first shell 111, convenient for applying external force, and then first shell easy to disassemble 111 to first shell 111
With second shell 112.In other embodiments of the invention, screw can also be used between first shell 111 and second shell 112
Connection or side hinged, the other side clamping, or the scheme of riveting etc..Certainly, first shell 111 and second shell
112 shape may be alternatively provided as round or shape of polygon etc., and the position for buckling 111a and card slot 112a can also root
It is arranged according to actual demand.
For the ease of the fixation and disassembly of display screen 200, in one embodiment of this invention, first shell 111 and/or
Second shell 112 is convexly equipped with fixed block 114 in the wall surface for forming air port 116, and an edge of fixed block 114 is used for and display
Screen 200, which abuts, to be fixed.Since display screen 200 is for showing projected picture, in order to guarantee to show the stability of picture, need to guarantee
The phenomenon that position of display screen 200 is fixed, and display screen 200 is avoided to shake under the action of air-flow, therefore, in this implementation, if
The fixed display screen 200 of fixed block 114 is set, in order to which display screen 200 keeps stablizing in accommodating cavity.As shown in Figure 4 and Figure 5,
One shell 111 and second shell 112 are equipped with fixed block 114, and fixed block 114 abuts two opposite tables of display screen 200 respectively
Face, and the lower edges of display screen 200 are abutted with the junction of first shell 111 and second shell 112.
Further, fixed block 114 is abutted with the edge of display screen 200.To reduce fixed block 114 and display screen 200
Contact area, and then avoid influencing the image quality that display screen 200 is projected out.In order to guarantee the fixed display screen 200 of fixed block 114
Stability, in the present embodiment, the quantity of fixed block 114 is multiple, multiple intervals of fixed blocks 114 setting.Meanwhile fixed block
114 are equipped with the positive stop lug boss 115 abutted with the side of display screen 200.Positive stop lug boss 115 is being accommodated for limiting display screen 200
On the one hand intracavitary position is convenient for determining on the other hand the position of display screen 200 can keep away display screen 200 in gas when assembling
Occurs mobile phenomenon under the action of stream.
As shown in Figure 4 and Figure 5, in the embodiment of the application, it is opposite with display screen 200 that frame body 110 is equipped at least one
Wall surface be equipped with perforative resigning mouthful 113, resigning mouthful 113 is for appearing display screen 200.The shape and display screen of resigning mouthful 113
The shape of 200 display picture parts is adapted, such as rectangle or circle etc..The use that can reduce raw material is arranged such,
It is also convenient for clearing up display screen 200 directly at resigning mouthful 113 simultaneously.When frame body 110 be equipped with a resigning mouthful 113 when, then with display
Opposite 110 part of frame body in another surface of screen 200, needs to use transparent material, so that display screen 200 can normal projection.
During flowing in frame body due to air, sinuous flow can be formed at resigning mouthful 113, leads to display screen 200
Heat dissipation effect is poor, for this purpose, display screen fixture 100 further includes an at least thermal insulation board 120,120 envelope of thermal insulation board in the present embodiment
Lid resigning mouthful 113.Thermal insulation board 120 is set, when display screen 200 on the one hand being avoided to work the flow that generates conduct to projector its
His position, while can guarantee that air-flow completely passes through display screen 200, to improve the radiating efficiency of display screen 200 to greatest extent.
In practical applications, thermal insulation board 120 selects transparent material, can select heat-protecting glass or acrylic board etc..Select heat-insulated glass
When glass, since heat-protecting glass can be preferably every removing the heat generated in 200 course of work of display screen, while color is nor affected on
Reduction, preferable drop shadow effect can be reached.
The present invention also proposes a kind of projector (not shown), which includes display screen 200 and display screen fixture
100, the specific structure of the display screen fixture 100 is referring to above-described embodiment, since this projector uses above-mentioned all implementations
Whole technical solutions of example, therefore at least all beneficial effects brought by the technical solution with above-described embodiment, herein not
It repeats one by one again.Cooling fan, and the hot channel being connected to heat dissipation grade are equipped in projector, equipped with display screen 200
Display screen fixture 100 is set in hot channel.Cooling fan rotation, to drive the air in hot channel to flow, Jin Ershi
Existing display screen 200 radiates.The projector can be portable projector, Multifunctional projector or smart projector etc..
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
