Equal with the projected area of projector；Described projector is projected on the white portion of belt when projection.This projection arrangement is tied
Structure is complicated, operation complexity, and relatively costly, promotes the use of difficulty in classroom bigger.
Summary of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, it is provided that a kind of high school student learns conventional projection
Instructional device, its projected position is adjustable so that will not take the usable floor area of blackboard during projection；Apparatus structure is simple, and cost is relatively
Low, it is simple to promote the use of.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is to be achieved through the following technical solutions:
A kind of high school student learns to use projection teaching's device, and including blackboard, scialyscope and projection screen, described scialyscope lower end sets
Having and be easy to its slide plate slided, the two ends of described slide plate are connected by suspension rod is fixing with the roof in classroom, the upper end of described blackboard
Being provided with guide rail, offer and be easy to the chute that projection screen upper end slide is movable in described guide rail, the two ends of described guide rail are arranged with
Rolling-up mechanism, the running roller of rolling-up mechanism described in two ends is attached by two slides of serving with projection screen upper end respectively, works as institute
State after a side region of blackboard writes, described projection screen by the rolling effect of side rolling-up mechanism to this rolling-up mechanism position
The place of putting moves, and described scialyscope carries out correspondingly position adjustments also by slip, thus realizes keeping the same of projection
Shi Jinhang position adjustments, the blackboard region do not write at rear conceded by projection screen.
Further, the lower end of described scialyscope is provided with sliding sleeve, and described sliding sleeve top offers the slide opening coordinated with slide plate,
Bottom offers pulling eye.
Further, described projection screen is the embossing plastics curtain of lighter in weight.
Further, the both sides, top of described slide are provided with the spacing preiection preventing from coming off.
Further, described rolling-up mechanism is driven by motor by running roller, and described motor is electrically connected with control device.
Further, described control device is hand push button device.
Compared with prior art, the invention has the beneficial effects as follows:
By arranging slide plate and guide rail, so that scialyscope and projection screen with transverse shifting, and then can make projection screen
The blackboard region do not write at rear can be conceded, while projection, improve the service efficiency of blackboard；Scialyscope position adjustment is led to
Crossing and manually pull, projection screen position adjustment is carried out by the rolling-up mechanism at two ends, and Setup Cost is relatively low, operates more convenient, real
Good by property.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach the above all advantage simultaneously.
