Abstract

The utility model relates to a multipurpose ruler with compasses function in the field of drawing tools, which is characterized in that a plurality of small circular holes are arranged at equal intervals on the graduations of the ruler. A center line formed by the centers of the small circular holes is a straight line vertical to the graduation line of the ruler. A long hole is arranged at the zero graduation of the ruler. The center line of the long hole in the length direction thereof coincides with the center line of the small circular holes. The minimum graduation line of the ruler is marked beside the long hole. The multipurpose ruler also comprises a positioning nail. When a circle needs to be drawn, the positioning nail is arranged inside the long hole. The multipurpose ruler is simple in structure, low in manufacture cost and convenient to use. Meanwhile, the accuracy of circles drawn by utilizing the ruler can be ensured.

Description

A kind of multipurpose ruler

Technical field

The utility model relates to the drawing instrument field, particularly a kind of multipurpose ruler with compasses function.

Background technology

Because the dimensions of compasses restriction usually can't be accomplished the picture circle requirement to big drawing.And the compasses cost of big specification is higher.At present, on the patent documentation many multipurpose chis are arranged on the market and both at home and abroad, these multipurpose rulers also have the compasses function except length, angular surveying function, the drawing function that the multiform shape also is provided that has.But still there are many deficiencies in these multipurpose rulers, the combination that belongs to ruler that has, and its complex structure causes manufacturing cost high, inconvenient operation.Though what have is simple in structure, precision is not high.

Summary of the invention

The utility model technical problem to be solved provides a kind of multipurpose ruler simple in structure, easy to use.

For solving the problems of the technologies described above, the technical scheme of the utility model is a kind of multipurpose ruler; Comprise rule; It is characterized in that be interval with some small sircle holes in that the scale of said rule is first-class, the center line that is formed centrally in said each small sircle hole is a straight line perpendicular to graduation mark; The zero graduation place of said rule is provided with a slotted hole, the center line of slotted hole length direction and the central lines of each small sircle hole, the other minimum scale line that indicates said rule of said slotted hole; Also comprise location nail, when needs are made bowlder, said location nail is installed in the slotted hole.

As preferably, said location nail comprises draw point, the seat that moves about, and the said seat that moves about is provided with the axle of through hole, and draw point places in the through hole, and the said seat that moves about can move in slotted hole perhaps to be fixed.

As preferably, the offset distance of said location nail in said slotted hole equals the spacing distance between the said small sircle hole.

When needs are made bowlder, the installing and locating nail inserts nib in certain small sircle hole in this slotted hole.Then, make the location ailing on the center of circle that will draw of institute, rotate rule and drive the nib that inserts in the small sircle hole to carry out picture round.

Simple in structure, the low cost of manufacture of the utility model, easy to use and can guarantee the accuracy of picture circle.

The specific embodiment

Like Fig. 1, multipurpose ruler shown in Figure 4, comprise the rule 6 of straight shape, be interval with some small sircle holes 12 in that the scale of rule 6 is first-class, the center line that is formed centrally in each small sircle hole 12 is a straight line perpendicular to graduation mark; The zero graduation place of rule 6 is provided with a slotted hole 10, the center line of slotted hole 10 length directions and the central lines of each small sircle hole 12, the slotted hole 10 other minimum scale lines that indicate rule 6; When needs are made bowlder, locate nail 11 and be installed in the slotted hole 10.

Fig. 2, multipurpose ruler shown in Figure 3, its rule is respectively drawing square and isoceles triangle chi.What followed closely their small sircle hole, slotted hole, location is provided with the above.

As shown in Figure 5, location nail comprises draw point 3, the seat that moves about, and the seat that moves about comprises the nut 2 that is positioned at rule 6 tops and the screw rod 7 of below, on nut 2 and the screw rod 7 coaxial through hole is arranged respectively, and draw point 3 places in the through hole.Go back mounting spring 4 and pad 5 between nut 2 and the screw rod 7, top cover 1 is installed on the nut 2, top cover 1 covers draw point 3.When the upper and lower of rule 6 was combined closely, the whole seat that moves about was fixing in slotted hole respectively for nut 2 and screw rod 7.

Take off the location nail, multipurpose ruler can be used for the measurement of length or angle.When needs are made bowlder, for example draw the circle that radius is 15.3cm, then will locate nail and place in the slotted hole, the skew of adjustment location nail in slotted hole makes the displacement of draw point 3 relative 0 scales be negative 0.3mm, and in the small sircle hole of 15cm scale, inserts nib.Then, make draw point 3 nail on the center of circle that institute will draw, in rotation one week of rule, then having accomplished radius is the accurate Drawing of the circle of 15.3cm.

Be without loss of generality, suppose that the spacing between each small sircle hole is 1cm, then the spacing distance that equals between the small sircle hole of the location nail distance that in slotted hole, can squint is 1cm.The other graduation mark that indicates of slotted hole is 1mm, and then the radius of circle precision of doing of the utility model is 1.0mm.

It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
