Description
Technical field
The utility model belongs to medical higher mathematics technical field, and in particular to a kind of higher mathematics plotter.
Background technology
As a basic science, higher mathematics has the characteristics of its is intrinsic, here it is the abstractness of height, tight logic
Property and being widely applied property.Abstractness and it is computational be that mathematics is most basic, most outstanding feature, have high abstraction and uniformly,
We could in depth disclose its essential laws, can just be allowed to be more widely used.Tight logicality refers in mathematics
In theoretical conclusion and arrangement, either concept and statement, or judge and reasoning, the rule of logic will be used, it then follows think
The rule of dimension.Thus, mathematics is also a kind of way of thinking, and the process of learning mathematicses is exactly the process of thinking training.Mankind society
Can progress, the extensive use with mathematics this science is undivided.Particularly to the modern times, the appearance of electronic computer and
Popularization cause mathematics application field more widen, modern mathematics just turn into development in science and technology very strong driving force, while also extensively and
Domain of the social sciences is in depth penetrated into.
Higher mathematics has become the required course of university, no matter what specialty is learned is, it is high to have to study in university
Mathematics, and in university's learning higher mathematics, no matter whether classroom has multimedia, teacher is required in the enterprising andante book of blackboard
Teaching, we will not also see that higher mathematics teacher only teaches higher mathematics with multimedia in university, because teacher knows
If for the writing of high number not writing on the blackboard step by step, student is difficult to understand for and learned, so for higher mathematics,
Be necessarily required to teacher and conscientiously write writing on the blackboard, but teacher is when writing writing on the blackboard, particularly with it is understood that figure for, teacher
Often freehand drawings is inaccurate, is difficult to understand for student, and study is got up also highly difficult.
Utility model content
The purpose of this utility model is to provide a kind of higher mathematics plotter, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of higher mathematics plotter, including it is transparent
Plate, the left and right sides of the transparent panel is equipped with support convex edge, and the lower end of the support convex edge is provided with sucker, the transparent panel
One side end face is provided with lifting magnet one, and the centre of the lifting magnet one is provided with the projection for being easy to pick up, the centre of the transparent panel
Hollow formation drawing placed layer, one end of the drawing placed layer is closed and the other end is provided with opening, the drawing placed layer
Rubber stopper is provided with opening, another side end face of the transparent panel is provided with lifting magnet two, the lifting magnet two and lifting magnet one
To opposite magnetic on the contrary, the lower end of the lifting magnet two is provided with spring, the lower end of the spring is provided with chalk placing tube.
It is preferred that, the quantity of the sucker is no less than four and respectively positioned at the two ends of supported on both sides convex edge.
It is preferred that, the height of the drawing placed layer is less than 0.5 centimetre.
Technique effect of the present utility model and advantage：The higher mathematics plotter, rational in infrastructure, drawing effect is good, passes through
Figure paper to be drawn is placed in drawing placed layer, by attracting each other for lifting magnet one and lifting magnet two, just can be described
Figure on figure paper, it is more accurate vivid compared to figure is withdrawn.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is side structure schematic view of the present utility model；
Fig. 3 is rubber plug structure schematic diagram of the present utility model.
In figure：1 transparent panel, 2 support convex edges, 3 lifting magnets one, 4 projections, 5 drawing placed layers, 6 suckers, 7 lifting magnets two, 8
Spring, 9 chalk placing tubes, 10 rubber stoppers.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of higher mathematics plotter as Figure 1-3, including transparent panel 1, described transparent
The left and right sides of plate 1 is equipped with support convex edge 2, and the lower end of the support convex edge 2 is provided with sucker 6, a side of the transparent panel 1
Face is provided with lifting magnet 1, and the centre of the lifting magnet 1 is provided with the projection 4 for being easy to pick up, the centre of the transparent panel 1
Sky forms drawing placed layer 5, and one end of the drawing placed layer 5 is closed and the other end is provided with opening, the drawing placed layer 5
Rubber stopper 10 is provided with opening, another side end face of the transparent panel 1 is provided with lifting magnet 27, the lifting magnet 27 and lifting magnet
1 to opposite magnetic on the contrary, the lower end of the lifting magnet 27 is provided with spring 8, the lower end of the spring 8 is provided with chalk placement
Cylinder 9, the quantity of the sucker 6 is no less than four and is located at the two ends of supported on both sides convex edge 2 respectively, the drawing placed layer 5
Highly it is less than 0.5 centimetre.
Operation principle：Figure paper to be drawn is placed in drawing placed layer 5, the edge of projection 4 on lifting magnet 1 is held
The line walking of figure paper, because lifting magnet 1 and lifting magnet 27 attract each other, the chalk in chalk placing tube 9 will be black
Identical figure is drawn out on plate, very accurately, image, the setting of sucker, convenient fixed transparent panel 1, the setting of spring 8 is prevented
