Abstract

The utility model relates to a mapping stationery or, more actually, a multifunctional scale. The utility model solves problems of prior mapping stationery of single mapping function, large volume occupied, and inconvenient carrying. The multifunctional scale comprises a graduated scale and an indexing disc marked with angles, wherein, one anterior angle of the graduated scale and the center of the cycle of the indexing disc are in a coinciding fixation; the multifunctional scale further comprises a hole-scale on which provided with a location hole, wherein, one end of the hole-scale is hinged with the center of the cycle of the indexing disc. The utility model fixes the graduated scale and the indexing disc and hinged with a hole-scale with a location hole which can rotate, thereby realizing the integration of multifunction of mapping tool. The utility model has the advantages of simple structure, convenient use, and easy carrying.

Description

Multifunctional ruler

Technical field

The utility model relates to a kind of drawing stationery, specifically is a kind of multifunctional ruler.

Background technology

In existing drawing stationery, for example: compasses, set square, rule, protractor etc., only has a kind of drawing function, therefore, when drawing, for example: draw arc, draw angle etc., needing different drawing instruments to cooperate finishes, if these drawing stationery all are placed in the writing case, it is big not only to occupy volume, and carries extremely inconvenient.

Summary of the invention

The utility model for solve existing drawing stationery drawing function single, occupy volume big, carry extremely inconvenient problem, a kind of multifunctional ruler is provided.

The utility model is to adopt following technical scheme to realize: a kind of multifunctional ruler, comprise rule and the index dial that is carved with angle, and an end angle of rule overlaps fixing with the center of circle of index dial; Comprise that also one has the hole chi of locating hole on it, an end of hole chi and the center of circle of index dial are hinged.During use, can make the circular arc of the circle of any radius in the certain limit, any radius and radian and can measure arbitrarily angled and length etc. by the cooperation between rule, index dial and the hole chi three.Compared with prior art, the utility model is fixed in rule in the center of circle of index dial, and, the drawing function of compasses, set square, rule, protractor is integrated in one at the hinged hole chi that has locating hole of the circle centre position of index dial, realized the multifunctional all of drawing instrument.

The utility model is fixed in index dial and rule together, and a hinged band locating hole rotatable hole chi, has realized the drawing instrument multifunctional all, and is simple in structure, easy to use, be easy to carry.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: the 1-rule; 2-hole chi; The 3-locating hole; The 4-index dial.

The specific embodiment

A kind of multifunctional ruler comprises rule 1 and the index dial 4 that is carved with angle, and an end angle of rule 1 overlaps fixing with the center of circle of index dial 4; Comprise that also one has the hole chi 2 of locating hole 3 on it, an end of hole chi 2 and the center of circle of index dial 4 are hinged.Locating hole 3 on the described hole chi 2 is corresponding with the scale on the rule 1.During concrete enforcement, can make rule 1 and index dial 4 integrated; In addition, in order to improve the drawing precision, the width of hole chi should be narrow as far as possible, can offer locating hole and get final product.

During concrete the use, the 3 corresponding index dials 4 of the locating hole on the pencil insertion hole chi 2 are rotated a circle can be obtained roundly accordingly, and rotating a certain angle to obtain corresponding arc; The center of circle that needs only index dial 4 when measuring angle overlaps with the summit at angle, and hole chi 2 and rule 1 overlap with two limits at angle respectively, and the angle that directly reads index dial 4 correspondences gets final product.Other function and common stationery are similar.

Claims (1)

1, a kind of multifunctional ruler comprises rule (1) and is carved with the index dial (4) of angle, it is characterized in that an end angle of rule (1) overlaps fixing with the center of circle of index dial (4); Comprise that also one has the hole chi (2) of locating hole (3) on it, the center of circle of an end of hole chi (2) and index dial (4) is hinged.
