Abstract

A multifunctional plotter comprises a straight scale and two set squares and is characterized in that two rows of bulges that are mutually parallel are fixed on each set square, wherein the distance between the two rows of bulges is equal to the width of the straight scale, so that the two rows of bulges and each set square body can form a clamping groove in which the straight scale can be inserted and connected; when the straight scale is inserted and connected into the clamping grooves, the straight scale and the set squares can perform relative slide under an applied force; and a circle drawing hole is arranged on each set square. The multifunctional plotter has the beneficial effects that the straight scale is inserted and connected into the clamping grooves of the two set squares; one circle drawing hole serves as the circle center; a pencil point is inserted into the other circle drawing hole to rotate so as to draw a circle; the multifunctional plotter has the original functions of the set squares and the straight scale, also can serve as a compass and an angle gauge and can accurately draw the circle and parallel lines; and the multifunctional plotter has the advantages that the multifunctional plotter has few articles and low cost, saves resources and is easy to carry and place and convenient to use.

Description

Multi-function drawing instrument

Technical field

The utility model relates to a kind of study and office appliance, particularly a kind of multi-function drawing instrument that collects set square, ruler, protractor, four kinds of functions of compasses.

Background technology

In study and work, when measurement and drawing point, line segment, angle, plane, stereogram, need use ruler, set square, compasses and protractor, at least to comprise a ruler, two set squares, a protractor, compasses, totally five, shortcoming is: the function singleness of each measurer, can not one-object-many-purposes, and number of packages is many, cost is high, cost is many, the waste resource; Number of packages is many, wedge angle is many, also be not easy to deposit and carry.

The utility model content

The purpose of this utility model is: for overcoming above-mentioned deficiency, the improvement structure of a kind of ruler and set square is provided, except the function of use of former ruler and set square, also can make compasses, protractor and use, provide promptly that a kind of number of packages is few, cost less, save resource, be easy to carry about with one, multi-function drawing instrument easy to use.

The technical solution adopted in the utility model is: a kind of multi-function drawing instrument, comprise a ruler, two set squares, it is characterized in that: all be fixed with two row's projectioies that parallel to each other and spacing equals the ruler width on described each set square, so that the common draw-in groove that constitutes for the described ruler of pegging graft between two row's projectioies and set square body, and in the time of in ruler is plugged on draw-in groove, can do relative slip under external force between ruler and set square, be equipped with the picture circular hole on described each set square.

Described picture circular hole is positioned on the protruding extended line of described set square edge.

The rectangular triangle of described set square, the straight line at described protruding place is parallel or vertical with the right-angle side on the set square.

Described projection is that one or more bar arrangement forms; Perhaps described projection is that two or more blocks arrangements form.

Be marked with the scale of tolerance angular dimension on described one of them set square.

The beneficial effects of the utility model are: ruler is plugged in the draw-in groove of two set squares, regulate the distance between two set squares, make on the set square two to draw the distance that distance between circular holes equals drawn circle, the interior sharp shaped materials such as nib, pin that insert of picture circular hole are done the center of circle therein, in another draws circular hole, insert nib rotations such as pencil, ball pen and get final product the picture circle, can replace compasses; Be marked with the scale of tolerance angular dimension on the set square, can make protractor and use; Except that set square, with original function of use of ruler, also can make compasses, protractor uses, and can accurately draw circle according to the big or small needs of circle; Object reduces, spends less, saves resource, is easy to carry about with one and deposits; Also has advantage easy to use, that can accurately draw circle and parallel lines.

Description of drawings

Fig. 1 is that the utility model is at the user mode schematic diagram of drawing less bowlder;

Fig. 2 is the user mode schematic diagram of the utility model when drawing than great circle;

Fig. 3 is a cutaway view of the present utility model;

Among the figure: 1 ruler, 2 first set squares, 3 second set squares, 4 first projectioies, 5 second projectioies, 6 draw circular hole.

The specific embodiment

As shown in Figure 1 and Figure 2, second set square 3 is the isosceles right angle triangle, is marked with the scale of tolerance angular dimension above so that this set square have set square, with the double duty of protractor.

As Fig. 1, Fig. 2, shown in Figure 3, first set square 2 and with second set square 3 on all be fixed with two row's projectioies, be respectively first projection, 4 and second projection 5, first projection 4 and spacing parallel to each other with second protruding 5 equates with the width of ruler, so that first projection 4, second projection 5, and the set square body between constitute draw-in groove for the grafting ruler, and the shape of two projectioies and position should make, in the time of in ruler is plugged on draw-in groove, can slide relatively under external force between ruler and set square.The position that is positioned at the extended line of certain row's projection on the set square is provided with picture circular hole 6, should have one on each set square at least and draw circular hole 6.

Above-mentioned projection can be that a bar is fixed on the single raised line that constitutes on the set square, shown in first projection 4 among Fig. 1, Fig. 2; Above-mentioned projection also can be to be arranged in the many raised lines that constitute on the same straight line by two or more bars, shown in second projection 5 among Fig. 1, Fig. 2; Above-mentioned projection can also be to be arranged in the projection formation that constitutes on the same straight line by two or more blocks, is similar to phantom line segments, does not draw.

As shown in Figure 1 and Figure 2, for ease of drawing big and less circle, above-mentioned picture circular hole 6 should be drilled in the position of closing on certain right-angle side on the protruding extended line, can draw the very little circle of diameter when two set square upper drawing circle holes 6 are adjacent as shown in Figure 1, two draw circular hole 6 and can draw the bigger circle of diameter when opposing as shown in Figure 2, the size of circle is subjected to the restriction of ruler length.

For ease of the accurate Drawing parallel lines, as shown in Figures 1 and 2: two set squares are right angled triangle, first projection 4, all parallel, vertical with another right-angle side with a right-angle side of set square with the extended line of second projection 5, make that when ruler 1 is plugged on two set squares corresponding right-angle side of two set squares is parallel to each other.

Shown in first set square 2 in left side among Fig. 1, Fig. 2, if first projection 4, vertical with long right-angle side with second projection 5, then in use, this long right-angle side is vertical with ruler, and it is easy to use that part user may feel.If first projection 4, vertical with short right-angle side with second projection 5 then can be plugged on ruler on two set squares and deposit, help further dwindling taking up room of multi-function drawing instrument.And second set square 3 on right side is an isosceles right triangle among the figure, does not relate to this problem.
