Abstract
The utility model relates to a mathematical education device of drawing, including the drawing chalk that is the hexagon structure, the drawing chalk is installed in the fixed cover of chalk, the fixed cover one end of chalk is connected with the marking off pole respectively, the marking off pole position is in the sliding chamber of the cover of ruling, the cover middle part lower extreme of ruling is equipped with the rotary rod, a rotary rod section is in the rotary sleeve, the rotary sleeve lower extreme is equipped with elastomeric suction cup. The utility model discloses during the use, the chalk of will drawing is installed in the fixed cover of chalk, then adsorbs elastomeric suction cup on the blackboard face, and the marking off pole is drawn the size along sliding chamber and is adjusted, then the drawing chalk to carry out 360o round the rotary sleeve under the effect of rotary rod rotatory, the circular of teacher's standard of drawing rapidly can help, let the mathematics mr instruct the student with more time and efforts, improvement the teaching efficiency, the practicality is good.
Description
Technical field
The utility model relates to instructional technology field, particularly relates to a kind of mathematical education drawing device.
Background technology
Mathematics, it is the subject of research respective real-world spaces form and quantitative relation, the one of formal science is belonged to viewed from certain angle. be divided into higher mathematics and elementary mathematics, also the set of handlebar senior middle school complexity, function, algebraically, geometry are called medium mathematics. it plays irreplaceable effect in development of human history and social life, is also study and the requisite basic tool of research modern science and technology.
On the mathematics class in middle school, during math teacher religion geometry, the figures such as picture circle, straight line are often needed to carry out aided education, but the circular standard being difficult to picture, result of calculation can be had influence on and thinking of solving a problem, if drawn circle with a compass, although standard is lost time, the larger operation inconvenience of compasses; Same, straight line also needs to draw with chi to keep straight.
Except school instruction, all need picture circle in the various occasion such as lecture, work, use traditional compasses drawing or free-hand drawing to compare and lose time, and one end of compasses is provided with needle point, has certain potential safety hazard.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mathematical education drawing device.
The utility model is achieved through the following technical solutions:
A kind of mathematical education drawing device, comprise the drawing chalk in hexagonal structure, described drawing chalk is arranged in chalk fixed cover, described chalk fixed cover one end is connected with scribing rod respectively, described scribing rod is positioned at the sliding chamber of line cover, lower end, described line cover middle part is provided with swingle, and described swingle one section is positioned at rotary sleeve, and described rotary sleeve lower end is provided with resilient suction cups.
As optimal technical scheme of the present utility model, described chalk fixed cover with between drawing chalk for clamping is connected.
As optimal technical scheme of the present utility model, between described scribing rod and sliding chamber, be provided with damping layer.
As optimal technical scheme of the present utility model, described rotary sleeve is fixedly connected with between resilient suction cups.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging scribing rod, line cover, swingle and rotary sleeve, when such teacher uses, drawing chalk is arranged in chalk fixed cover, then resilient suction cups is adsorbed on blackboard panel, scribing rod carries out the adjustment of drawing size along sliding chamber, then drawing chalk carries out 360o rotation around rotary sleeve under the effect of swingle, the circle of the rapid drawing standard of teacher can be helped, the more time and efforts of math teacher is allowed to instruct student, improve efficiency of teaching, practicality is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. line cover; 2. swingle; 3. rotary sleeve; 4. resilient suction cups; 5. slide chamber; 6. scribing rod; 7. chalk fixed cover; 8. drawing chalk.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of mathematical education drawing device, comprise the drawing chalk 8 in hexagonal structure, described drawing chalk 8 is arranged in chalk fixed cover 7, wherein said chalk fixed cover 7 with between drawing chalk 8 for clamping is connected.Described chalk fixed cover 7 one end is connected with scribing rod 6 respectively, and described scribing rod 6 is positioned at the sliding chamber 5 of line cover 1, is provided with damping layer, can keeps the stability after the stretching out of scribing rod 6 like this between wherein said scribing rod 6 and cunning chamber 5.In the middle part of described line cover 1, lower end is provided with swingle 2, and described swingle 2 one sections is positioned at rotary sleeve 3, and described rotary sleeve 3 lower end is provided with resilient suction cups 4, and wherein said rotary sleeve 3 is fixedly connected with between resilient suction cups 4.
Its detailed description of the invention is: when teacher uses like this, drawing chalk 8 is arranged in chalk fixed cover 7, then resilient suction cups 4 is adsorbed on blackboard panel, scribing rod 6 carries out the adjustment of drawing size along sliding chamber 5, then drawing chalk 8 carries out 360o rotation around rotary sleeve 3 under the effect of swingle 2, can help the circle of the rapid drawing standard of teacher, allows the more time and efforts of math teacher instruct student, improve efficiency of teaching, practicality is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
