Abstract
The utility model discloses a kind of language teaching multi-media classroom projection screen, including receiver, control chamber and curtain, described receiver is internally installed rotary shaft, and receiver one end is provided with control chamber, described control chamber is internally installed motor, and motor is connected with rotary shaft by motor output shaft, and described rotary shaft is provided with curtain, and curtain extends to outside receiver through receiver, described control chamber is connected with controlling switch by wire.This utility model, by arranging ink layer, can block ambient light and absorb ambient light, thus can effectively reduce the ambient light impact on imaging picture, and the projection screen made can not be disturbed by ambient light.Even if under the irradiation of highlighted ambient light, projection screen of the present utility model can present projected picture clearly equally, thus can be greatly expanded its range of application, can be not only used for without in the environment of high light it can also be used to have in the environment of high light.
Description
Technical field
This utility model relates to application apparatus technical field of imparting knowledge to students, and is specially a kind of language teaching multi-media classroom projection screen
Curtain.
Background technology
Multimedia teaching refers in teaching process, according to instructional objectives and the feature of teaching object, by Instructional Design,
Rationally select and use Modern Teaching Medium, and with Traditional teaching means organic assembling, jointly participate in whole course of teaching, with multiple
Media information acts on student, forms rational teaching process structure, reaches optimized teaching efficiency.But, the most existing
Some multi-media classroom projection screens its poor stability in use, particularly can produce when teacher's pointer is encountered and rock, during use
Inconvenience, the most traditional projection screen can only allow screen move bottom to, and traditional projection screen is often located at black
The upper end of plate, also exists the problem that blackboard is blocked by screen completely, is unfavorable for imparting knowledge to students.Therefore, based on these problems, it is provided that
Screen is stretched flat function by one, makes screen can be pulled out to the language teaching multi-media classroom projection screen of random length simultaneously
Have important practical significance, and existing curtain is easily subject to the impact of light.
Utility model content
The purpose of this utility model is to provide a kind of language teaching multi-media classroom projection screen, to solve above-mentioned background
The problem proposed in technology.
For achieving the above object, this utility model provides following technical scheme: a kind of language teaching multi-media classroom projects
Screen, including receiver, control chamber and curtain, described receiver is internally installed rotary shaft, and receiver one end is provided with control
Case processed, described control chamber is internally installed motor, and motor is connected with rotary shaft by motor output shaft, described rotary shaft
On curtain is installed, and curtain extends to outside receiver through receiver, described control chamber by wire with control switch even
Connect.
Preferably, described curtain bottom is provided with weight linear meter.
Preferably, described curtain is provided with ink layer.
Preferably, described receiver bottom is provided with outlet, and outlet two ends are provided with electric pushrod.
Preferably, inside and outside clearing apparatus and the lower clearing apparatus of being separately installed with of described receiver, and upper cleaning
Device and lower clearing apparatus lay respectively at the both sides of curtain.
Compared with prior art, the beneficial effects of the utility model are: this utility model, by arranging ink layer, can block
Ambient light also absorbs ambient light, thus can effectively reduce the ambient light impact on imaging picture, and the projection screen made can not be by ring
The interference of border light；Even if under the irradiation of highlighted ambient light, projection screen of the present utility model can present equally to be thrown clearly
Shadow picture, thus its range of application can be greatly expanded, can be not only used for without in the environment of high light it can also be used to there is the environment of high light
In, by arranging upper clearing apparatus and lower clearing apparatus, curtain can be cleaned so that it is keep clean, electronic by arranging
Machine and electric pushrod, can control the lifting length of curtain.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-4, a kind of embodiment that this utility model provides: a kind of language teaching multi-media classroom projection screen
Curtain, including receiver 1, control chamber 3 and curtain 2, receiver 1 is internally installed rotary shaft 8, and receiver 1 one end is provided with control
Case 3 processed, control chamber 3 is internally installed motor 4, and motor 4 is connected with rotary shaft 8, in rotary shaft 8 by motor output shaft
Being provided with curtain 2, and curtain 2 through receiver 1 and extends to receiver 1 outside, control chamber 3 is by wire 5 and control switch 6
Connecting, curtain 2 bottom is provided with weight linear meter 7, and curtain 2 is provided with ink layer 12, and receiver 1 bottom is provided with outlet 11, and
Exporting 11 two ends and be provided with electric pushrod 13, receiver 1 is inside and outside is separately installed with clearing apparatus 10 and lower cleaning dress
Put 9, and upper clearing apparatus 10 and lower clearing apparatus 9 lay respectively at the both sides of curtain 2.
Specifically used mode: in utility model works, according to using needs, by controlling switch 6 control motor 4,
And then control rotary shaft 8 rotates, thus realizing the lifting of curtain 2, and the clearing apparatus at curtain 2 two ends, curtain 2 can be carried out clearly
