Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of exhibiting device of being convenient to show that teaching appurtenance such as wall chart uses.
Background technology
In teaching process, 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 at present.According to teaching requirements; 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 then need teacher to prepare a large amount of writings on the blackboard, so the clipboard gathering of calligraphers takies more time in classroom on the classroom; Thereby influenced the propagation of course progress, be unfavorable for the raising of quality of instruction with extracurricular knowledge.
The utility model content
The utility model technical matters to be solved provides a kind of simple in structure, controls teaching exhibiting device easy to use.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the teaching exhibiting device; Comprise framework; Parallel rotation is provided with upper winding shaft and the lower winding shaft that supports drape in the said framework, and said upper winding shaft and lower winding shaft are fastened on the spool drive unit on the said framework respectively, and said spool drive unit is connected with driving control device; Said base of frame is provided with the framework direction adjusting apparatus.
As the improvement to technique scheme, said spool drive unit comprises motor, and the output shaft synchrodrive of said motor connects said upper winding shaft and lower winding shaft.
As the improvement to technique scheme, said driving control device comprises the controller that is fixed on the said framework, and said controller is electrically connected said motor, and the control panel of said controller is provided with the control button of the said electrical machine working mode of control.
As the improvement to technique scheme, said framework direction adjusting apparatus comprises the connecting link that is fixed on said framework lower end, and said connecting link is rotatably connected to pedestal.
Owing to adopted technique scheme; The teaching exhibiting device; Comprise framework; Parallel rotation is provided with upper winding shaft and the lower winding shaft that supports drape in the said framework, and said upper winding shaft and lower winding shaft are fastened on the spool drive unit on the said framework respectively, and said spool drive unit is connected with driving control device; Said base of frame is provided with the framework direction adjusting apparatus; The beneficial effect of the utility model is: the teacher will give lessons, and the extracurricular content of expanding outside class write on curtain formula instruments such as drape by the time; When giving lessons, drape is fixed between upper winding shaft and the lower winding shaft, and, realizes the up scrolling or the control of descending scrolling of drape through the control of driving control device to spool drive unit duty; Thereby realize the displaying of the content of courses; Help to practice thrift the classroom writing on the blackboard time, increase the extracurricular content of courses, improve the quality of teaching.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: the 1-framework; The 2-upper winding shaft; The 3-lower winding shaft; 4-drape 5-controller 6-controls button; The 7-connecting link; The 8-pedestal.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
Like teaching exhibiting device shown in the drawings; Comprise framework 1; The parallel upper winding shaft 2 and lower winding shaft 3 that supports drape 4 that be provided with will be fixed on the drape 4 of the content of courses between upper winding shaft 2 and the lower winding shaft 3 during use in the said framework 1, and the coboundary of drape 4 is fixed on the upper winding shaft 2; And the lower limb of drape 4 is batched fixing along lower winding shaft 3 peripheries, rely on batching of 2 pairs of drapes 4 of upper winding shaft that drape 4 is moved up in use and show the content of courses.
The said upper winding shaft 2 of present embodiment is fastened on the spool drive unit on the said framework 1 respectively with lower winding shaft 3; Said spool drive unit is connected with driving control device; Said spool drive unit comprises motor, and the output shaft synchrodrive of said motor connects said upper winding shaft 2 and lower winding shaft 3, and motor can drive upper winding shaft 2 and lower winding shaft 3 speed operation together in the same way in use; With stationarity and the synchronism that guarantees that drape 4 moves, thereby the content on the drape 4 can be displayed clearly; Said driving control device comprises the controller 5 that is fixed on the said framework 1; Said controller 5 is electrically connected said motor; The control panel of said controller 5 is provided with the control button 6 of the said electrical machine working mode of control; Control button 6 comprises the uplink synchronization control button of motor start and stop control button, upper winding shaft and lower winding shaft and the DL synchronization control button of upper winding shaft and lower winding shaft; And the DL synchronization of the uplink synchronization of upper winding shaft and lower winding shaft control button and lower winding shaft control button relies on controller 5 control motors respectively positive and negatively transfers realization; The control method of 5 pairs of motor positive and inverses of controller is the content that those of ordinary skill is known in the present technique field, here repeats no more.Controller 5 be installed in framework 1 edge by under the position, be convenient to the teacher and control use.
The said framework of present embodiment 1 bottom is provided with the framework direction adjusting apparatus; Said framework direction adjusting apparatus comprises the connecting link 7 that is fixed on said framework 1 lower end; Said connecting link 7 is rotatably connected to pedestal 8; Utilize relatively rotating of connecting link 7 and pedestal 8, can regulate the direction of framework 1 easily, the student of being convenient to each orientation can see.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
