Description
Technical field
It the utility model is related to projection auxiliary equipment field, specially a kind of projector curtain of indoor reflection-proof.
Background technology
Projection screen is used in film, office, home theater, in convention occasion.For display image, video text
The instrument of part, the projection screen time is relatively smooth smooth with the region that its surface has afterwards long, so easily produces mirror-reflection
And cause reflective, and influence to be sitting in the viewing effect of side, and surface can accumulate certain dust to projection screen over time, this
Sample can also influence display effect, therefore it is very necessary to design a kind of projector curtain of indoor reflection-proof for problem above
's.
Utility model content
For problem present in background technology, the utility model provides a kind of projecting apparatus curtain of indoor reflection-proof
Cloth.
To achieve the above object, the utility model provides following technical scheme：A kind of projecting apparatus curtain of indoor reflection-proof
Cloth, including curtain cylinder, rotating shaft, motor and projection screen, the rotating shaft are installed in curtain cylinder, the rotating shaft one end and driving
Motor is connected, and projection screen upper end edge is connected with rotating shaft, and the projection screen includes being connected with basic unit in turn, dissipated
Thermosphere and frosted layer, the winding mouth edge of the curtain cylinder are provided with hairbrush bar, and the hairbrush bar is close to frosted layer surface.
The utility model pass through motor rotation control projection screen winding and decentralization, projection screen by basic unit,
Heat dissipating layer forms with frosted layer, and the effect of heat dissipating layer is can to disperse the heat for the luminous energy being projected on projection screen, frosted
The effect of layer is to increase the degree of roughness on surface, prevents from being brought by mirror-reflection reflective, winds and transfers in projection screen
During, hairbrush bar can rub to the frosted layer of projection screen, and the effect of friction on the one hand can be by frosted layer
Dust removes, and on the other hand can carry out friction treatment to frosted layer, increase the degree of roughness on its surface, effectively prevent by unrestrained anti-
Penetrate bring it is reflective.
As a kind of preferable technical scheme of the utility model, the projection screen lower end is provided with weight linear meter.
As a kind of preferable technical scheme of the utility model, the winding mouth of the weight linear meter and curtain cylinder matches.
As a kind of preferable technical scheme of the utility model, several suckers are equidistantly provided with the weight linear meter.
As a kind of preferable technical scheme of the utility model, the hairbrush strip adoption plastic wire or polypropylene brush filament system
Into.
Compared with prior art, the beneficial effects of the utility model are：The utility model global design is by setting up hairbrush
Bar can play cleaning dust effectively prevents reflective effect, global design structure with increasing the degree of roughness on projection screen surface
Brief and practical, there are more wide market prospects, be easy to promote.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
Fig. 1 to Fig. 4 is referred to, the utility model provides a kind of technical scheme：A kind of projecting apparatus curtain of indoor reflection-proof
Cloth, including curtain cylinder 1, rotating shaft 2, motor 3 and projection screen 4, the rotating shaft 2 are installed in curtain cylinder 1, the rotating shaft 2 one
End is connected with motor 3, and the upper end edge of projection screen 4 is connected with rotating shaft 2, and the projection screen 4 is included successively
Basic unit 5, heat dissipating layer 6 and frosted layer 7 are connected with, the winding mouth edge of the curtain cylinder 1 is provided with hairbrush bar 8, the hairbrush bar 8
It is close to the surface of frosted layer 7.
The utility model controls the winding and decentralization of projection screen 4 by the rotation of motor 3, and projection screen 4 is by base
Layer 5, heat dissipating layer 6 form with frosted layer 7, and the effect of heat dissipating layer 6 is can to dissipate the heat for the luminous energy being projected on projection screen 4
Go, the effect of frosted layer 7 is to increase the degree of roughness on surface, prevents from being brought by mirror-reflection reflective, is wound in projection screen 4
During decentralization, hairbrush bar 8 can rub to the frosted layer 7 of projection screen 4, on the one hand the effect of friction can incite somebody to action
Dust on frosted layer 7 removes, and on the other hand can carry out friction treatment to frosted layer 7, increase the degree of roughness on its surface, have
Effect prevents from being brought by diffusing reflection reflective.
Specifically, the lower end of projection screen 4 is provided with weight linear meter 9, can by projector's curtain stretching and leveling, when project
It is better.
Specifically, the winding mouth of the weight linear meter 9 and curtain cylinder 1 matches, winding mouth progress that can be to curtain cylinder is close
Envelope.
Specifically, being equidistantly provided with several suckers 10 on the weight linear meter 9, can be inhaled by sucker and metope
With making projection screen being fixed prevents from rocking.
