Abstract

The utility model relates to a multifunctional and convenient ruler, which is a tool to replace a straight ruler and a protractor and a divider to draw straight lines and oblique lines and various parallel lines. The utility model is characterized in that two straight rulers are combined into a T-square through a slide plate; one ruler (movable ruler) transversely moves on the other ruler (fixed ruler) following the slide plate, and a plurality of parallel lines can be drawn; besides, an included angle between the movable and the fixed ruler can be adjusted by the moveable ruler, and the rotating angle of the movable ruler can be shown through the angle scales on the end of the movable ruler and the slide plate; therefore, various oblique lines can be drawn, and parallel oblique lines can be drawn by moving the sliding plate.

Description

The multifunctional convenient chi

The utility model is a kind of chi.It is the instrument that substitutes ruler, protractor, branch programming straight line, oblique line, various parallel lines.

Draw squares Graphing of Engineering, student, understand in system chart, art designing's font and the various graphic designs, the different angles of usually will drawing, different equidistant straight line, oblique line and various parallel lines.There is following shortcoming when the ruler that uses draws parallel lines at present: the one, line is difficult to the parallel of picture with line; The 2nd, for satisfy between line and the line apart from size, two the auxiliary vertical lines that need draw earlier on the both sides of drawing paper get size with the divider amount and are marked on this vertical line, then the ruler line; The 3rd, the picture oblique line must measure the required oblique line that draws after the number of degrees are put on a little with protractor, if draw oblique parallel lines, also will repeat above-mentioned steps.There is this as seen, draws an engineering drawing the simplest or other chart, need carry out numerous and diverse program with instruments such as ruler, protractor, set square, dividers.And quality also is difficult to guarantee that efficient is very low.

The purpose of this utility model provides a kind of multi-functional convenient ruler, and it can draw boost line, without steps such as divider span punctuates, directly draw various straight lines, parallel lines, and need not be equipped with protractor, set square draw various oblique lines, oblique parallel lines in addition.

The purpose of this utility model is achieved in that with two rulers and is combined into the T-square type by slide plate, and chi vertically moves laterally along another chi, and this chi is moving chi.And another chi maintenance is motionless, and this chi is a scale.Moving chi angle with scale in slip is constant, so along moving drawn line and the line keeping parallelism of chi.The moving drawn size of line between the position on the drawing and line and line of chi sees that directly the size scale on the scale is determined the distance that moving chi vertically moves along scale.In addition, moving chi can rotate 0～90 ° round the dog screw on the slide plate along horizontal plane, the angle between adjustment and scale.And can show the angle of moving between chi and moving chi starting point and moving chi and scale by the scale on moving chi chi end and the slide plate.By adjusting moving chi angle, the required various oblique lines that draw, the moving slide board various oblique parallel lines that draw again apart from size.When moving chi went to scale overlapping (angle is 0), moving slide board obtained extending the effect of ruler.

Owing to adopt technique scheme, reduced multiple instrument, simplified paint program, improved operating efficiency and quality greatly.

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

Fig. 1 the utility model multifunctional convenient chi embodiment principles of construction figure.

Fig. 2, Fig. 3 the utility model multifunctional convenient chi use illustration.

Among Fig. 11, scale 2, moving chi 3, slide plate 4, setscrew nut 5, dog screw 6, angle index

Be installed on the scale (1) at Fig. 1 middle slide plate (3), slide plate (3) is gone up longitudinal sliding motion at scale (1).Moving chi (2) is installed on the dog screw (5) on the slide plate (3).In the longitudinal sliding motion of scale (1) upper edge scale (1) chi face, moving chi (2) can rotate round dog screw (5) along horizontal plane moving chi (2), please see Figure 1 double dot dash line position with slide plate (3).And by the chi end of moving chi (2) and the corner of the moving chi (2) of the demonstration of the scale on the slide plate (3).When moving chi (2) goes to the purpose that scale (1) overlapping (angle is 0) removable slide plate (3) reaches the elongation ruler.Setscrew nut (4) is that fastening nut makes the chi angle orientation after adjusting moving chi angle.

Shown in Figure 2ly drawing lines 0～90 ° the time when institute, aligns with the trimming in the left side that scale is placed on paper, shown in Figure 3ly when 90～180 ° in drawn lines, can align the bottom that scale is placed on paper with the trimming, 180 °～360 ° the right that are placed on paper or above.

The position and the lines length that are drawn lines on paper please see that the chi size scale determines, between lines and lines apart from size, by seeing scale size scale (slide plate slides distance).

Claims

1, a kind of multifunctional convenient chi is to be combined by slide plate by two rulers, it is characterized in that: have a slide plate to be installed on the scale, along the scale longitudinal sliding motion, moving chi is installed on the dog screw on the slide plate, laterally move with slide plate, and the dog screw that can center on the slide plate rotates along horizontal plane.

2, it is characterized in that according to the described multifunctional convenient chi of claim 1: the chi end that has of moving chi is half garden shape, and there is the aperture of 1 installation dog screw at the center, and is carved with angle along semicircle chi end.
