Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of teaching exhibiting device.
Background technology
In teaching process, more and more using multimedia teaching at present, generally is to combine with computing machine by projector, and the student is given lessons, and can alleviate teacher's burden like this, improves the quality of teaching.Because classroom instruction and actual socio-cultural the contact are more and more paid attention in teaching, but the spreading range of the lecture contents of therefore imparting knowledge to students becomes big.According to the teaching requirement, the teacher needs to give lessons to be extended to aspect the extracurricular knowledge in teaching process, if the on-the-spot expansion content of arranging on the classroom, then need teacher to prepare a large amount of writings on the blackboard, therefore the clipboard gathering of calligraphers takies more time in classroom, thereby influenced the propagation of course progress and extracurricular knowledge, be unfavorable for the raising of quality of instruction.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of simple in structure, control easy to usely, and the energy computing machine combine the teaching exhibiting device of improving the quality of teaching with wall chart.
Its technical scheme is: the teaching exhibiting device, the display screen that is connected with projector on comprising base and being arranged on described base, one side of described display screen is provided with telescopic fixed leg, on the described fixed leg framework is installed, parallel rotation is provided with upper winding shaft and the lower winding shaft that supports drape in the described framework, described upper winding shaft and lower winding shaft are fastened on the motor on the described framework respectively, and described motor is connected with control device.
Described control device comprises the controller that is fixed on the described framework, and described controller is electrically connected described motor, and the control panel of described controller is provided with the control button of the described machine operation of control.
The utility model has the following advantages compared with prior art: simple in structure, reasonable in design, control easy to usely, and can computing machine combine with wall chart, improved quality of instruction.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, the teaching exhibiting device, the display screen 2 that is connected with projector on comprising base 1 and being arranged on described base 1, one side of described display screen 2 is provided with telescopic fixed leg 3, on the described fixed leg 3 framework 4 is installed, parallel rotation is provided with upper winding shaft 6 and the lower winding shaft 7 that supports drape 5 in the described framework 4, and described upper winding shaft 6 and lower winding shaft 7 are fastened on the motor on the described framework 4 respectively, and described motor is connected with control device.
Described control device comprises the controller that is fixed on the described framework 4, and described controller 8 is electrically connected described motor, and the control panel of described controller 8 is provided with the control button 9 of the described machine operation of control.
During use, the teacher will give lessons, and the extracurricular content of expanding outside class write on drape 5 instruments such as formula such as curtain such as grade by the time, when giving lessons, drape 5 is fixed between upper winding shaft 6 and the lower winding shaft 7, and by the control of control button 9 realizations to electric machine operation state, realize up scrolling or the control of descending scrolling of drape 5, thereby realize the displaying of the content of courses, help to save the classroom writing on the blackboard time, increase the extracurricular content of courses, improve the quality of teaching.Like this when carrying out multimedia teaching, not only the content on the display screen 2 is carried out Projection Display by projector, also can directly carry out Projection Display to the content on the drape 5, can pass through fixed leg 3 installation frames 4 according to the classroom needs, thereby show the content on the drape 5, make things convenient for teacher to impart knowledge to students like this, need not to prepare or the interpolation knowledge content in the classroom, can alleviate teacher's burden, improve quality of instruction.
