Abstract

The utility model relates to a multifunctional drawing plate for students, which belongs to drawing tools. A transparent plate composed of a rectangular ruler and a semicircle protractor is provided with graduations on the two sides, wherein, one side is drilled with holes for drawing any circle. The plate surface is provided with drawing grooves and template frames for drawing any equilateral triangle, equilateral quadrangle, equilateral pentagon, equilateral hexagon, triangle and curve. The plate is provided with a rectangular frame which is provided with a movable parallel line ruler for drawing parallel lines. Integrated with the functions of a parallel meter, a compasses, a protractor, a straightedge, a set square and a T square, the drawing plate has the advantages of rapid and easy drawing, simple structure and convenient carrying.

Description

Multifunctioanl drawing board for students

The utility model belongs to drawing instrument, particularly student's learning performance drawing instrument.

The patent No. is that 88214366.2 multifunctional drawing board is the transparent panel that is made of semicircle protractor and rectangle model chi, on drawing board, have the groove of conveniently drawing various figures, can be convenient, accurately promptly draw any positive three, positive four, positive five, regular hexagon, the model circle, ellipse and curve etc., but can not draw parallel lines and the circle of more size, the patent No. is that 89204961.8 " multifunctional cylinder parallel rule " is though solved the problem that draws parallel lines, but structure is complicated, roller frame is set, the architectural feature that has surmounted dull and stereotyped chi, student's inconvenience is carried, and cost is higher.

The purpose of this utility model is the innovation again to " multifunctional drawing board ", on drawing board, newly be provided with one movably parallel ruler draw parallel lines, the edge along the long limit of drawing board is drilled with some apertures, be used for drawing a picture bowlder internal point and draw the selected element of any radius of circle, enlarge the scope of picture circle.

The purpose of this utility model is to realize like this, the student is that the semicircle protractor of diameter constitutes with multifunctional drawing board by a rectangular slab and with the rectangular slab minor face, transparent, making ruler at the long limit of rectangle chi plate high scale uses, both sides scale symmetry is consistent, be drilled with some apertures on the long limit therein, the aperture arrangement that is in line along the chi limit, draw bowlder, one eyelet is overlapped with selected centre point, inject a tip of a pencil or other small round bar is fixed, again by selected another eyelet of required radius of circle size, inject another tip of a pencil, rotating a circle around center of circle centering bar is drawn as the circle of required size.Have a slot on the plate face with respect to the protractor other end, slot is the hole periphery with the periphery of drawing board, and on the relative both sides of scale, cross-over connection one is the parallel rule piece slidably, by the equidistant parallel lines that can draw of scale translation.Have right angle, acute triangle model hole in the upper right side of slot, there is curved grooves on the upper left side, near semicircle protractor position, has positive three, positive four, positive five, regular hexagon center and summit line groove, for drawing arbitrarily corresponding polygon usefulness.

The utility model collects the function of measurers such as parallelometer, compasses, protractor, ruler, set square, T-square in a chi, can be fast, accurately, the various figures that run in the simplified drawing student study, simple in structure, a plate is used more, be easy to carry, cheap.

Accompanying drawing is used the multifunctional drawing board sketch for the student.

1 parallel ruler is equated by two width, thin lucite sheet different in size is bonded, and the short-movie termination makes step, and step surface is an adhesive surface, fit back short-movie and lengthy motion picture constitutes a groove, and this groove then is a parallel ruler at the drawing board rectangle frame sliding tray on the periphery relatively.

2 circular holes bore aperture along drawing board rectangle chi plate one long limit, and aperture is advisable to inject a nib, and arrange in a straight line along long limit in each hole.

The student can make thickness of slab 1-2 millimeter with transparent plastic or lucite with multifunctional drawing board.

Claims (1)

1, the student uses multifunctional drawing board, be to be the transparent panel of the semicircle protractor formation of diameter on a rectangle chi plate minor face and with the minor face, have model picture frame and the groove of painting various figures on the plate face, it is characterized in that: on one side of drawing board, be drilled with some apertures, the aperture arrangement that is in line along the limit, have the rectangle frame on the drawing board face, on the two relative edges of scale, being crossed with one can be along the parallel ruler that parallel lines are used of drawing of edge slip.
