Description
Technical field
The utility model belongs to teaching aid technical field, particularly relates to a kind of mathematics diagraph.
Background technology
At present, in mathematical education process, often need mapping explanation demonstration on drawing board, especially geometry sum functions explanation, mapping becomes important auxiliary explanation means, but the method that math teacher mainly adopts now is Hand drawing, the hand-held drawing instrument of teacher and chalk are drawn on drawing board, when especially painting circle, more complicated, hand-held compasses, should ensure that the center of circle is constant, ensure that radius is constant again, be difficult to operation.
Utility model content
The object of the utility model embodiment is to provide a kind of mathematics diagraph, and be intended to solve in Hand drawing complexity of drawing, be difficult to operation, drawing instrument takes up room greatly, inconvenience of taking, the problem that compasses point is easily hurted sb.'s feelings.
The utility model is achieved in that this mathematics diagraph comprises: handle, rotating shaft, positioning support leg, articulated joint, ball groove, rubber suction cups, drawing supporting leg, drawing pen, sizing chi, chi groove, alignment pin, dip stick, chi box; The upper end of positioning support leg is connected by rotating shaft with the upper end of drawing supporting leg, rotating shaft is provided with handle, positioning support leg lower end is provided with articulated joint, rubber suction cups is connected with articulated joint by ball groove, sizing chi is installed in the middle part of positioning support leg, sizing chi is provided with chi groove, a midleg of drawing is provided with alignment pin, alignment pin matches with chi groove, the bottom of drawing supporting leg is provided with chi box, be provided with dip stick in chi box, dip stick is connected with the lower end of positioning support leg, and drawing supporting leg lower end is provided with drawing pen.
Further, positioning support leg is provided with scale.
Further, positioning support leg and drawing supporting leg are provided with damping spring plate on the contact surface of rotating shaft place.
Further, described drawing pen is provided with sheath.
Further, described articulated joint adopts globular hinge head.
According to the circular size needs of drafting, sizing chi regulates drawing angle, and dip stick draws circular diameter for measuring; Positioning support leg is adsorbed on drawing board by rubber suction cups and is fixed, carry out picture operation by drawing pen.After finishing using, sheath is covered on drawing pen, avoid drawing pen and hurt sb.'s feelings.
The advantage that the utility model has and good effect are: this mathematics diagraph integrates the function of compasses, protractor, ruler, pen, and structure is simple, convenient and swift during drawing, can ensure that the center of circle is constant, can ensure that again radius is constant; Positioning support leg and drawing supporting leg can fold preservation, take up room little; Adopt rubber suction cups to replace probe stationary positioned supporting leg, and sheath is covered on drawing pen, avoid probe and drawing pen is hurted sb.'s feelings.
