Abstract
The utility model relates to a braille drawing template, which comprises an upper template and a baseplate, wherein, a coordinate frame and a geometric figure frame are arranged on the upper template; the frame edges adopt continuous wave gears; and the geometric figure frame is a complex figure frame including a trigonometric function figure frame, a parabola figure frame and the like. The utility model, which is mainly used for enabling blind children to draw and identify the geometric figures, has the characteristics of simple operation, convenient use and the like.
Description
Technical field
The utility model belongs to blind person's schooling apparatus technical field, specifically relates to a kind of blind person knowledge figure template of drawing.
Background technology
Draw is that the puzzlement blind child is familiar with a geometric difficult problem always, and particularly for trigonometric function, parabola figures, existing braille letter stencil, word pen can't be finished mapping, have influence on understanding and the drafting of blind child to complex figure, are unfavorable for blind child's intellectual development.
Summary of the invention
The purpose of this utility model provides geometric templates such as a kind of blind person's of being convenient to drafting and understanding function.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises cope match-plate pattern and base plate, cope match-plate pattern is provided with graphical boxes, position corresponding with graphical boxes on the base plate is provided with depression, also be provided with the coordinate frame on the cope match-plate pattern, the corresponding coordinate cave battle array that is provided with on the base plate, graphical boxes is the trigonometric function picture frame, cope match-plate pattern is provided with handle, cope match-plate pattern and base plate flexibly connect by connecting pin, and the edge of coordinate frame and graphical boxes is the continuous wave tooth, and ripple mark of mouth place is relative with depression.
The utility model cope match-plate pattern is provided with coordinate frame and graphical boxes, corresponding coordinate cave battle array and the figure cave battle array of being provided with on the base plate, coordinate frame and graphical boxes edge are provided with the continuous wave tooth, during mapping, paper is put between cope match-plate pattern and the base plate, wield the pen along the waveform edge of figure with the braille pen, and start writing at the depression place, can draw out coordinate and corresponding geometric figure, simple to operate, easy to use.
