Abstract

The utility model relates to a transparent square grid drawing ruler which can draw a square grid and can divide a picture plane into a plurality of small square grid picture planes. The utility model uses 25 20 mm real line regular square grids which are contained in the 100 mm regular square grid and 100 divided 10 mm broken line regular square grids as reference, and a vertical real line is made into a groove for drawing square grids. Bu using a square grid picture on the drawing ruler, the picture plane is divided into a plurality of small picture planes, and by drawing the small picture planes, the whole picture is finished. If the picture plane is beyond the size of the drawing ruler, and a part of the picture can be partially put in the drawing ruler and is finished.

Description

The picture chi given birth in many evenly slot type pattern small characters

Originally practical relating to, replace ruler drawing, especially a width of cloth drawn to be divided into several little pictures and quick draw square method.

At present, known ruler whenever draws a straight line, and must move once, if adopt the ruler drawing.Method is: the size of this width of cloth picture of root a tree name, the view picture picture is stamped grid; Use the same method again and on drawing paper, make an onesize grid; So, just can clearly see each little picture, draw more convenient.But this way not only wastes time and energy, and is difficult for adopting.

The purpose of this utility model provides a kind of picture chi, and a kind of 100mm grid square contains the ruler that groove is arranged of the little grid square of 100 10mm; It can be drawn a width of cloth and be distributed in the lattice of several 10mm; And only need move 4 times and just can be drawn as the little grid square that the 100mm grid square includes 100 10mm.

The purpose of this utility model is achieved in that on the foursquare transparent plastic sheet of 130mm, the grid square that a 100mm is arranged, it is divided into the solid line grid square of 25 20mm and the dotted line grid square of 100 10mm, make scale up and down, perpendicular solid line is done grooving, paintbrush can be moved up and down in groove.Please examine.Drawing chi moves and once prolongs groove six the long 100mm that can draw, the straight line of spacing 20mm; With six horizontal solid lines and six perpendicular solid line quadratures, can form the square (solid line) of 25 20mm; Use five horizontal dotted lines and five perpendicular dotted lines again, the little grid square of each 20mm is divided into 4, just become the lattice of 100 10mm, this is identical with form on drawing chi.Be put on the picture drawing chi, can see clearly that by the transparency chi picture is divided into the square little picture of several 10mm.The student dabs off the form line on the drawing paper as long as progressively little picture is drawn, and just can finish this width of cloth and draw, and reaches the purpose of drawing.Can not disposable covering whole image if draw chi, this width of cloth can be drawn and be divided into the square part of several 100mm and finish.

Owing to adopted such scheme, can improve greatly qualitatively with on the speed in drawing, and teacher's dependence is reduced.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure chart that the utility model is drawn the embodiment of chi.

Fig. 2 is the graticule that Fig. 1 draws.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is the I-I cutaway view of Fig. 1.

In Fig. 1, manifest the solid line on groove and terraced edge, only represent the junction on two planes in the picture chi.Groove width 1mm, a perpendicular solid line is all contained as graticule line in the centre of each groove.The making and settlement of these grooves are for the draw square pattern is prepared; The ladder edge, right side of groove can make paintbrush be tilted to the right, and setting-out is convenient; Drawing solid line lattice and dotted line lattice on the chi, is for making things convenient for vision, seeing picture easily clearly and be in which grid; The scale of drawing chi is equipped with 2 benefits up and down: 1, picture is produced the sense of a kind of yardstick intuitively; 2, help the picture segmentation.The scale that grid is outer is the scale that remedies in the groove; The top of drawing chi is for its object that made is described with " pupil draws chi ".The periphery of drawing chi only plays reinforcing picture chi and does usefulness.What the picture chi was used is that transparent plastic is made material, and thickness makes between the 1mm-2mm.

Claims (3)

1, a kind of picture chi, if the ruler drawing, need be at the grid that draws simultaneously on the drawing paper and on the picture, ruler will move many times, it is characterized in that: many evenly slot type setting-outs, move 1 many equidistance of can drawing, and parallel straight line, two groups of solid line quadratures can be formed: (groove number-1) ²Individual grid; Divide (groove number-1) equally with two groups of quadrature dotted lines again ²Individual grid just obtains 4 (groove numbers-1) ²Individual grid; So draw square only needs mobile picture chi 4 times.

2, the described picture chi of root a tree name claim 1 is characterized in that: pattern, its number of squares are 4 (groove numbers-1) ²

3, root a tree name claim 1,2 described picture chis is characterized in that: scale, graticule line and font account for one side; And the right of groove ladder is along accounting for another side.
