Abstract

A multifunctional drawing instrument for students is provided, which comprises a triangular plate body, an angle gauge arranged at one corner of the triangular plate body, a sinusoidal curve provided at the horizontal side of the angle gauge, at least two circles and ellipses of different semi-diameters arranged at the edges of the corner where the angle gauge is located, and a hexagonal member and a square member both arranged above the angle gauge. The multifunctional drawing instrument for students has simple structure, multiple functions and good duration; and is particularly suitable for primary and middle school students. The multifunctional drawing instrument integrates the functions of angle gauge, triangular plate and straight ruler and adds various shapes such as curves, circles, ellipses and polygons thereto; and can meet the daily needs of students.

Description

The multifunctional student drawing instrument
Technical field
The utility model relates to a kind of student appliance, the drawing instrument that particularly a kind of students in middle and primary schools use always.
Background technology
Set square, protractor, ruler are the drawing instruments of normal use during students in middle and primary schools learn, and tradition is used is three kinds of instruments independently separately.Also have in the prior art above-mentioned three kinds of instruments that set of tools is integrated, as Chinese patent 2004201164034 disclosed " four unification drawing rulers ", around having one, this drawing instrument indicates the rectangular slab of scale, there is the protractor of band pointer the centre, and set square, also have polygon and circle, oval figures in the protractor bottom.The deficiency of its existence is that structure is too complicated, and students in middle and primary schools in use damage easily, and manufacturing process complexity, and cost is higher.
Summary of the invention
The utility model has designed a kind of multifunctional student drawing instrument at the problems referred to above, has solved the deficiency that above-mentioned prior art exists.
Multifunctional student drawing instrument of the present utility model, comprise a set square main body, near an angle of set square main body, be provided with protractor, it is characterized in that described protractor horizontal line one side is provided with sine curve, the circle that is provided with at least two different radiis along the opposite side of protractor angle of living in is provided with hexagon and square with oval above protractor.
Described multifunctional student drawing instrument, it is characterized in that described set square is a right angle triangle that contains 60 degree angles, the base of described protractor is parallel with the hypotenuse of set square, sine curve is positioned at a side of protractor and along the setting of set square hypotenuse, described different radii circle is provided with along 60 degree angle institute opposite side with oval.
Described multifunctional student drawing instrument is characterized in that described set square is the isosceles right angle triangle, and protractor places near the acute angle angle.
Multifunctional student drawing instrument of the present utility model, simple in structure, multiple functional, solid durable.Being fit to students in middle and primary schools uses.Protractor and set square, ruler are integrated and have increased curve and circle, ellipse and polygonal shape onboard, the student is with an instrument can satisfy daily need.

Fig. 2 is the another kind of structural representation of multifunctional student drawing instrument
The specific embodiment
With reference to accompanying drawing multifunctional student drawing instrument of the present utility model by a set square main body, on one of this set square or two or three limits, the length scale is arranged, a protractor is set near one of them angle, and the base of protractor is parallel with a limit of set square.One side of protractor is a sine curve, and this sine curve is the slit that directly makes a treaty 1 to 1.5mm sinusoidal shape on set square plate face, with can draw a sine curve along the slit.Be provided with the circular hole and the elliptical aperture of different radii along the opposite side at angle, protractor place, the circle and the length radius that are provided with radius in the present embodiment respectively and are 2mm, 4mm, 6mm, four specifications of 8mm are respectively 8mm: two ellipses of 4mm and 6mm: 2mm.Regular hexagon hole and square hole that on top, protractor arc top a length of side to be arranged respectively be 4mm and 6mm.The student directly can draw described figure with pen in use in the hole.
An embodiment of the present utility model is that the set square main body is a right angled triangle, and one of them acute angle is 60 degree.Three length of sides are respectively 30 centimetres, and 40 centimetres, 50 centimetres.Protractor places near the 60 degree angles, and the base of protractor is parallel with hypotenuse.Sine curve places protractor one side, and is provided with along the set square hypotenuse.Circular port and slotted eye are provided with along 60 degree angle institute opposite side.The making material of this set square main body is identical with existing student appliance making material.
Another embodiment of the present utility model is that the set square main body is an isosceles right triangle, and protractor is arranged near the acute angle, and the base of protractor is parallel with hypotenuse.Sine curve and protractor are adjacent and along the hypotenuse setting.

Claims (3)
