Abstract
The utility model relates to an instruments used for education technical field especially indicates a mathematics plotter is used in teaching, including the chi body, chi body one side is equipped with the scale mark, chi body opposite side is equipped with wavy line, be equipped with the drawing board on the chi body, the utility model discloses an above -mentioned technical scheme's beneficial effect as follows: simple structure, the technique is equitable, and convenient to use synthesizes multiple graphics primitive, can satisfy the drawing requirement of different figures, need not change different graphics primitives, has improved drawing efficiency, in addition, sets up by the drawing board, and teacher's required roughly figure and numerical value of drawing on the blackboard that can draw on the drawing board has further improved drawing efficiency.
Description
Technical field
The utility model relates to technical field of teaching instruments, refers to a kind of teaching digital drafting instrument especially.
Background technology
At present, the digital drafting instrument of teaching is of a great variety, there are ruler, set square, compasses etc., these digital drafting instrument devices are all generally single pure, function is comparatively single, can not meet the demand of multiple drawing, some larger drawing instrument simultaneously, because it can not split, carry inconvenience.In addition, teacher needs to mark some numerical value, if the numerical value of required mark is more when drawing usually, and the figure of painting is comparatively complicated, teacher can not disposablely remember, often will turn round and see bookish former figure, so just greatly reduce the efficiency of mathematical education.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of teaching digital drafting instrument, comprehensive multiple drawing instrument, and sets up by drawing boards, for drawing the roughly figure and numerical value of drawing on blackboard needed for teacher, substantially increases the efficiency of mathematical education.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of teaching digital drafting instrument, comprises chi body, and described chi body side is provided with graduation mark, and described chi body opposite side is provided with wave, and described chi body is provided with drawing boards.
As preferably, described chi body is also provided with set square combination.
As preferably, described chi body is also provided with the circle of different-diameter.
As preferably, described chi body is also provided with protractor.
As preferably, described chi body is also provided with ellipse.
As preferably, described chi body also has additional two standing grooves, in described standing groove, be placed with compasses and drawing pen.
As preferably, described chi body side is provided with some jacks, for inserting the chalk of different colours.
As preferably, described chi body thickness is 5cm to 7cm.
The beneficial effect of technique scheme of the present utility model is as follows: structure is simple, technology is reasonable, easy to use, comprehensive multiple drawing instrument, can meet the drawing requirement of different graphic, different drawing instruments need not be changed, improve drawing efficiency, in addition, set up by drawing boards, the roughly figure of drawing on blackboard needed for teacher can draw on drawing boards and numerical value, further increase drawing efficiency.
Accompanying drawing explanation
Fig. 1 is that a kind of teaching of the utility model uses the structural representation of digital drafting instrument embodiment.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of teaching digital drafting instrument for existing deficiency, comprise chi body 1 as shown in Figure 1, described chi body 1 side is provided with graduation mark, described chi body 1 opposite side is provided with wave 7, described chi body 1 is provided with drawing boards 5, the roughly figure of drawing on blackboard needed for teacher can draw on drawing boards 5 and numerical value, further increase drawing efficiency, described chi body 1 is also provided with set square combination 4, the circle 3 of different-diameter, protractor 2 and oval 6.Described chi body 1 also has additional two standing grooves 8, in described standing groove 8, be placed with compasses 9 and drawing pen 10.
As shown in Figure 2, described chi body 1 side is provided with some jacks 11, and for inserting the chalk of different colours, chi body 1 thickness is 5cm to 7cm.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
