Description
Technical field
The utility model relates to a kind of drainpipe, is specially the drawing board that a kind of College Mathematics Teaching uses.
Background technology
Higher mathematics is the core curriculum of university, higher mathematics is by simple infinitesimal calculus, Probability Theory and Math Statistics, and deep algebra, geometry, and they ask the basic subject that intersection is formed, mainly comprise infinitesimal calculus, all kinds of textbook in other aspects slightly difference.Present teacher is saying higher mathematics class hour, can use without any teaching aid, often needs on blackboard, draw some figure, curves etc.Due to existing blackboard not having coordinate, grid, add the difficulty that teacher draws, and there is larger error in the figure drawn, cause the shape of function curve inaccuracy, figure nonstandard, the visual experience of student can be affected, cause teaching efficiency poor further, on the other hand, more existing teaching aid structures are complicated, financial cost is high, placement is inconvenient.
Utility model content
The purpose of this utility model is just the drawing board providing a kind of College Mathematics Teaching to use to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: the drawing board that a kind of College Mathematics Teaching uses, comprise drawing board, Drawing zone, reference axis, fan-shaped Probability Region, hook, hand-strap, rotating shaft, supporting leg and leg, it is characterized in that: described Drawing zone is the cross spider be anyhow evenly distributed be printed on drawing board, described reference axis and fan-shaped Probability Region are all positioned at Drawing zone, and the center of circle of fan-shaped Probability Region and reference axis initial point overlap, described hook is positioned at the top of drawing board, and symmetrical distribution, described hand-strap is positioned in the middle of drawing board top, described rotating shaft is positioned at the middle and lower part at the back side of drawing board, described supporting leg symmetry is established on the rotary shaft, and be fixedly connected with 120 degree, rotating shaft, described leg is located on supporting leg.
Preferably, be provided with permanent magnet in described drawing board, drawing board lower end is provided with a rubber layer, and the described drawing board back side is provided with the groove of one and support section same shape.
Preferably, the color of described fan-shaped Probability Region is different from other parts of Drawing zone.
Preferably, described rotating shaft terminal is provided with projection.
Preferably, described support section comprises rotating shaft, supporting leg and leg, and the thickness of described support section is less than the degree of depth of groove.
Compared with prior art, the beneficial effects of the utility model are: the drawing board that this College Mathematics Teaching uses is reasonable in design, and structure is simple, and result of use is good, student can be made to learn abstract concept fast, and can grasp fast; Have and manufacture the advantage simple, cost is low, simultaneously, this device is placed convenient, both be placed on magnet board by permanent magnet, again by hanging on wall, or be placed on lectern by support section, teacher draws out corresponding figure when explaining mathematical problem fast and accurately by this device.
Accompanying drawing explanation
