Abstract
The utility model relates to a multifunctional drawing plate for drawing. A penetration opening scale using either diameter of a circular plate as the central line is designed, and another scale is designed on the diameter which vertically intersects the central line (the diameter) of the opening scale. The circular plate is also provided with concentric circles which are equally spaced and lines equally dividing angles which equally divide circumferential angles, and the point that the lines equally dividing an angle intersect every circumferential line of the concentric circle is provided with a pen hole. Thus, integrated with the functions of a straightedge, a protractor, a set-square and a coordinatometer, with flexible application, the drawing plate can satisfy the needs of students and the requirements of general drawing, conveniently, rapidly and canonically completing the drawing.
Description
The utility model relates to the multifunctional drawing board of a kind of student and general drawing usefulness, also can draw for other and use.
At present, student and the general various tool of employed traditional drawing instrument for separating of drawing are as ruler, protractor, set square, coordinatometer of right angle, complex plane chi, polar coordinates chi etc., when using these instruments to draw, step is various, and speed is slow, lack of standardization, especially to student's inconvenience.
The purpose of this utility model just is: design a kind ofly especially to student and the general multifunctional drawing board of drawing and being suitable for, integrate the function of ruler, protractor, set square, coordinatometer.
The utility model is to realize its purpose like this: arbitrary diameter with a garden shape plate penetrates the opening rule for center line designs one, and design has another rule on another diameter of hang down handing over this opening rule diameter of living in (center line), also design has equally spaced concentric garden on the shape plate of garden, and designing the five equilibrium angle line that five equilibrium garden round angle is arranged, design has a hole in contour intersection, garden, the concentric garden of five equilibrium angle line and each.
The utility model can also be realized its purpose like this: the size in the width of opening rule and a hole and the size of drawing pen tip adapt, so that can insert the drawing pen of all size easily, as pencil, carbon ink pen etc., are convenient to graphed.
Design has contiguous block on the garden shape plate at opening rule of the present utility model two ends.
Because the utility model adopted above-mentioned structural design, the opening rule can work as ruler, garden shape plate work as protractor, opening rule and work as set square, coordinatometer etc. with another rule of its friendship of hanging down.So it integrates the function of ruler, protractor, set square, coordinatometer, can use for student and general the drawing, it is applied in a flexible way, except that the function of finishing ruler, protractor, set square, coordinatometer, can also decide the point in rectangular coordinate plane, complex plane, the polar coordinates plane, make parallel lines, perpendicular bisector, draw convex polygon, polyhedron, rotary body and more complicated figure, the mapping step is very simple, easily and fast, standard.
Further described below in conjunction with drawings and Examples, but specific embodiments of the present utility model is not limited in the specific descriptions among this accompanying drawing embodiment.
Fig. 1 is a structural representation of the present utility model.
As shown in FIG., arbitrary diameter with a garden shape plate (1) is that center line designs and produces an opening rule (2) that penetrates, and design has another rule (3) on another diameter of hang down handing over this opening rule (2) diameter of living in (center line), also design and produce equidistantly the concentric garden (4) in (adjacent garden between week apart from equating) on the garden shape plate (1), and work has the five equilibrium angle line (5) of five equilibrium garden round angle, five equilibrium angle line (5) has designed and produced a hole (6) with the contour intersection, garden in each concentric garden (4), for inserting various drawing pens.Going up design at the garden, two ends of opening rule (2) shape plate (1) has contiguous block (7), makes the two halves garden of being cut apart by opening rule (2) connect into integral body.The size and the drawing pen tip of the width of opening rule (2) and a hole (6) adapt, and the tip of the drawing pen of all size can be inserted, and carry out graphed.Material of the present utility model generally can adopt transparent lucite manufacturing.
Be illustrated for the utilization of this multifunctional drawing board being described, giving some instances below.
1. connect regular polygon in the drafting garden.Its method is that utilization waits the method in branch garden week to do, promptly according to the limit number of regular polygon, calculate its center angle number, utilize garden shape plate (1) to make protractor then, cooperate concentric garden (4), five equilibrium angle line (5) and a hole (6), make the position of the point that equates with the central angle number of degrees on paper, connect each point in turn and get final product.The external circle radius of its regular polygon is determined by corresponding garden radius with one heart.
2. make parallel lines.Its method is to find out the angle line of two supplementary angles and the intersection point of garden, concentric garden (4) contour on garden shape plate (1), i.e. a hole (6), and retouch on paper, connect each garden, concentric garden (4) intersection point on week respectively and get final product.As the intersection point (hole) of the angle line of the garden contour in second concentric garden and the 3rd concentric garden among the figure and 60 ° and 120 ° is retouched out, connect two intersection points of garden on week in the second concentric garden and the 3rd concentric garden respectively, promptly draw parallel lines.Can certainly utilize the intersection point (hole) of same concentric garden garden contour and two supplementary angles angle lines and vertical angles angle line thereof to draw.
3. make trapezoidal, rectangle, parallelogram, square etc., its method is made parallel lines and can be finished with method described in 2.
4. make the vertical line of straight line or line segment.The rule (3) of the straight line on the known paper or line segment and this drawing board is coincided, insert in the opening rule (2), can finish with nib.Also can make the perpendicular bisector of line segment with this method.
5. make any rhombus.The garden heart with this drawing board garden shape plate (1) is made intersection point, draws orthogonal two line segments dividing equally, connects four end points then in turn and promptly finishes.
6. as this drawing board is made coordinatometer of right angle and protractor usefulness, the point that can make the rectangular coordinate system of any definite value and include also can be made convex polygon.
Also available oblique two survey the audio-visual picture that the technique of painting is made various convex polygons, or survey the audio-visual picture that the technique of painting is made the garden with just waiting.If on demand with line segment or the different in addition combination of curve, can obtain more complicated polyhedron or rotary body figures to the above figure.Also can amplify like principle and dwindle figure in conjunction with the position.
Illustrate: clear for drawing, only drawn in this accompanying drawing and partly waited branch angle line (5) and a hole (6).
Claims (3)
1, a kind of multifunctional drawing board that is used to draw, it is characterized in that: design one with arbitrary diameter of a garden shape plate for the center and penetrate the opening rule, and with another diameter that opening rule diameter of living in hang down to be handed over mutually on design another rule is arranged, also design has equally spaced concentric garden on the shape plate of garden, and designing the five equilibrium angle line that five equilibrium garden round angle is arranged, the five equilibrium angle line has a hole with each contour intersection, garden, concentric garden design.
2, multifunctional drawing board according to claim 1 is characterized in that: the size in the width of opening rule and a hole and the size of drawing pen tip adapt.
