The demonstration board comprises a bottom board, the upper edge of the bottom board is provided with a telescopic boom, the telescopic boom is provided with a spindle, the spindle is provided with a telescopic scale, the right side part of the bottom board is provided with a demonstration disk, the demonstration disk is adsorbed on the bottom board through a bottom sucker. The demonstration board disclosed by the utility model has the beneficial effects that the demonstration board has a simple structure, the construction operation is simple, time-saving and labor-saving in the mathematical teaching process, the working difficulty of the teacher is lightened, and the trigonometric function can be intuitively demonstrated so that the student can understand conveniently.
Description
Technical field
The utility model relates to a kind of mathematical education demonstration board, belongs to the teaching appliance technical field.
Background technology
At present, the explanation of need to mapping on blackboard frequent in the mathematical education process is demonstrated, and prior art is mainly to hold on the other hand fixedly ruler high by the teacher, a hand-held chalk mapping, and operation extremely bothers, wastes time and energy like this, has increased work difficulty to the teacher.In addition, trigonometric function occupies important position in mathematics, a plurality of theorems, definition and formula have wherein been designed, but the student is difficult for memory in the process of study, cause the teaching and learning process in effect undesirable, affect the enthusiasm of Students ' Learning, brought unnecessary worry to the mathematics teacher simultaneously.
Summary of the invention
The purpose of this utility model be overcome the deficiencies in the prior art and provide a kind of in the mathematical education process easy and simple to handle, time saving and energy saving, the mathematical education demonstration board that facilitates student memory to understand of mapping.
For reaching above purpose, the utility model adopts following technical scheme: the mathematical education demonstration board, comprise base plate, it is characterized in that: the coboundary at base plate is provided with telescopic arm, telescopic arm is provided with rotating shaft, rotating shaft is provided with shrinkage-rule, is arranged with demonstration board in the right side of base plate, and demonstration board is adsorbed on base plate by the sucker of bottom surface.
Further, described demonstration board surface is provided with rectangular coordinate system and the circle take the rectangular coordinate system initial point as the center of circle, and rectangular coordinate system indicates scale, and the circle outer shroud is marked with angle, and the place is articulated with pointer at initial point, and this pointer is articulated with scale with the circle intersection.
The beneficial effects of the utility model are: simple in structure, map in the mathematical education process easy and simple to handle, time saving and energy saving, and alleviated teacher's work difficulty, can demonstrate trigonometric function intuitively, facilitate the student to understand.
Description of drawings
In order to be illustrated more clearly in the technical solution of the utility model, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model system framework figure.
Embodiment
below in conjunction with accompanying drawing, the technical solution of the utility model is explained in detail, in conjunction with Fig. 1, the mathematical education demonstration board, comprise base plate 1, coboundary at base plate is provided with telescopic arm 2, telescopic arm is provided with rotating shaft 3, rotating shaft is provided with shrinkage-rule 4, when mapping in the mathematical education process, regulating shrinkage-rule 4 mappings gets final product, be arranged with demonstration board 5 in the right side of base plate 1, demonstration board is adsorbed on base plate 1 by the sucker 6 of bottom surface, described demonstration board 5 surfaces are provided with rectangular coordinate system and the circle take the rectangular coordinate system initial point as the center of circle, rectangular coordinate system indicates scale, the circle outer shroud is marked with angle, the place is articulated with pointer 7 at initial point, this pointer is articulated with scale 8 with round intersection, can demonstrate easily trigonometric function.
The above person, being only preferred embodiment of the present utility model, is not to limit practical range of the present utility model, and namely all equalizations of doing according to the utility model change and modify, be all the utility model claim scope and contain, give an example no longer one by one here.
