Abstract
The utility model provides a multi-purpose drawing rule which is mainly composed of a base rule and a movable rule. The movable rule is levelly arranged at the lower edge of the base rule, and a semicircle boss whose center of a circle penetrates through the centre line of the movable rule and is marked with angular indexing lines is arranged on the base rule. The semicircle boss is connected together with the movable rule by a rivet shaft. The short section of the movable rule which is started from the center of the rivet shaft can be rotated below the semicircle boss, and a through groove is arranged on the central line of the long section. A movable pen holding appliance is arranged on the through groove. The multi-purpose drawing rule can be used or drawing straight lines, oblique lines, circular arc lines, and can also be used as a protractor. The utility model has the advantages of simple structure and convenient operation. The multi-purpose drawing rule is especially suitable for use by drawing personnel.
Description
The utility model relates to a kind of improved drawing rule, particularly a kind of drawing rules of using more.
As everyone knows, existing drawing rule all is the more single drawing rule of function ratio as ruler, set square, angle square etc., will use corresponding drawing rule during drawing according to different lines, therefore has a hunch not very convenient.Especially for the drawing personnel that are engaged in civil engineering, often to arrive building-site and draw, carry manyly ruler, also be the thing of inconvenience.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of drawing rule of using easy to use is provided more.
Task of the present utility model realizes in this manner: this drawing rule is made up of basic chi and moving chi, moving chi is a ruler, be flat on the base of basic chi, on basic chi, be provided with a center of circle is provided with the branch angle index by moving chi center line, outer rim semicircle boss, and link together with a riveting axle and moving chi, the short section that moving chi begins from riveting axle center all can be rotated below the semicircle boss, a center line has a groove in the long section upper edge of moving chi, is provided with one and can movably writes device along what groove moved and can clamp by what hollow bolt and nut constituted on groove.
The utility model can be made following several purposes:
1, when not rotating moving chi, uses with the former function of basic chi.
2, can make angle square uses.
3, when needs are drawn oblique line, as long as just will move chi and turn to required angle and can draw.
4, when needs are drawn certain section radian, move to after desired location and fastening the getting well as long as will write device, insert pencil and can draw this arc length.
This shows that this drawing rule compared with prior art has the multipurpose advantage, and simple in structure, and is easy to use.
Below in conjunction with accompanying drawing structure of the present utility model and embodiment are further described:
Fig. 1 is the front view of a kind of concrete structure of the utility model.
Fig. 2 is that Fig. 1 is along A-A line cutaway view.
Fig. 3 is user mode figure of the present utility model.
Fig. 4 is the front view of another embodiment of the utility model.
As attached illustrated in figures 1 and 2, basic chi of the present utility model (1) and moving chi (2) are made with transparent plastic, and the semicircle boss (3) that is carved with angular indexing is injection molded with basic chi (1) disjunctor.Moving chi (2) is flat on the base of basic chi (1), its center line is by the center of circle of semicircle boss (3), base chi (1) links together with a riveting axle (4) by semicircle boss (3) center of circle with moving chi (2), moving chi (2) can rotate around riveting axle (4), riveting axle (4) can be made of a nut (7) and a T type circle bolt (8), with the convenient for assembly and adjustment degree of packing, but its bottom surface will flush with moving chi (2) bottom surface.Can establish a bulge loop (9) in the lower end of T type bolt flange, on semicircle boss (3), be provided with corresponding annular groove (10), to obtain concentricity preferably.Have a groove (5) that is provided with size scale at moving chi (2) from long section (11) center of riveting axle (4) beginning, this groove (5) preferably passes to the center of riveting axle (4), and the line that drafting is come out can pass to the center of circle.On the groove (5) of moving chi (2), also be carved with dimension line, so that measure.Write device (6) and constitute,, and can be clamped on a certain position so that can move along groove (5) by a hollow bolt (14) and a nut (15).Thread segment at hollow bolt (14) preferably has two balanced surfaces, and its width is just identical with groove (5), and bolt (14) is not rotated, and nut (15) is rotatable, is convenient to slide and screw.Base chi (1) can be ruler, set square and angle square.The terminal of the moving short section of chi (2) (12) preferably flushes with basic chi (1), so that draw out vertical line.In order to make chi (2) when rotating, can obtain smoothness preferably, the Lower Half terminal in short section (12) has the arc surface (16) that engages with semicircle boss (3) inner cylinder face, and has the annular groove (13) that can allow short section (12) first half embed on the inner cylinder face of semicircle boss (3).
The utility model is suitable for the drawing worker to be used.
Claims (5)
1, a kind of drawing rule of using more, it is characterized in that forming by basic chi (1) and moving chi (2), moving chi (2) is a ruler, be flat on the base of basic chi (1), on basic chi (1), be provided with a center of circle by moving chi (2) center line, outer rim is provided with the semicircle boss (3) of branch angle index, and link together with a riveting axle (4) and moving chi (2), the short section (12) that moving chi (2) begins from riveting axle (4) center can be rotated in semicircle boss (3) below, long section (11) at moving chi (2) has a groove (5) along center line, on groove (5), be provided with one by hollow bolt (14) and nut (15) constitute can along groove (5) move also can clamp movably write device (6).
2, drawing rule according to claim 1 is characterized in that riveting axle (4) is to be made of a nut (7) and a T type bolt (8).
