Abstract

The utility model relates to realia, in particular to a multifunctional ruler for drawing dashed lines and dot dash lines. The multifunctional ruler adopts the structure that a plurality of rectangular small holes on two straight lines are hollowed out from a common ruler main body; the sizes of the small holes are on one straight line are the same; the sizes of the small holes on the other straight line alternate; the two rows of small holes are parallel to each other; and a millimeter graduation line is arranged between the rows of small holes. The utility model solves the problem that a middle school student and relevant engineering technical personnel cannot draw a dashed line or a dot dash line in one step while drawing.

Description

A kind of dotted line and dashdotted multi-functional ruler of drawing

Technical field

The utility model relates to a kind of realia, especially relates to a kind of dotted line and dashdotted multi-functional ruler of drawing.

Background technology

At present, known ruler is to be carved to be attached on the rectangular transparent plastic by millimeter rule and corresponding scale to be made.And teachers ' teaching, the student is several how to draw, and often will draw dotted line and chain-dotted line when correlation engineering technical staff draws, and does not but have a kind of instrument can satisfy this requirement.And now people's common practice is on paper, is relying on the graduated one side of ruler, and draw dotted line and chain-dotted line are done very inconveniently, and not attractive in appearance like this, and the line that draws is nonstandard, and time loss is big.People expect can directly draw a dotted line and a dashdotted instrument.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model provides a kind of dotted line and dashdotted multi-functional ruler of drawing, and it can solve the problem in the reality.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of dotted line and dashdotted multi-functional ruler of drawing, several big or small alternate rectangle apertures on the big or small identical rectangle aperture on the same straight line and several same straight lines are set on the common ruler main body, this two rows aperture be arranged in parallel, between two row's apertures a millimeter graduation mark is set.

The beneficial effects of the utility model are to have solved daily life middle school student and correlation engineering technical staff and can not go out dotted line and dashdotted problem by unicursal when mapping.

Description of drawings

Fig. 1 is a main body schematic diagram of the present utility model.

Among the figure: the common ruler main body of 1-; 2-draws the aperture of dotted line; 3-draws the chain-dotted line aperture; 4-millimeter graduation mark.

The specific embodiment

Below in conjunction with the detailed embodiment of the present utility model of accompanying drawing:

In Fig. 1, on common ruler main body 1, cut out several on same straight line big or small identical rectangle aperture and constitute the aperture 2 of picture dotted line, cut out several on same straight line big or small alternate rectangle aperture and constitute picture chain-dotted line aperture 3, this two rows aperture be arranged in parallel, and increases a millimeter graduation mark 4 newly between two row's apertures.

When concrete the use, as draw dotted line, earlier the utility model is placed on the correct position of paper, according to the length of the actual dotted line that will draw, and utilize two scales on the rule between the little pore area, get final product with on the aperture 2 of drawing dotted line, the draw dotted line of appropriate length of pen.If will draw chain-dotted line, earlier the utility model is placed on the correct position of paper, according to the actual dashdotted length that will draw, and utilize two scales on the rule between the little pore area, get final product at the chain-dotted line of drawing the appropriate length of drawing on the dashdotted aperture 3 with pen.

Realize that dotted line and the dashdotted multi-functional ruler preferred plan of drawing of the present utility model is to be material with plastics, utilize the basic equipment of chi tool factory, take to produce by batch in a large number, with the supply teaching, the demand of engineering drawing so just can realize the practical value and the economic worth of can draw dotted line and dashdotted multi-functional ruler of the present utility model better.

Claims

1. can draw dotted line and dashdotted multi-functional ruler, it is characterized in that, several big or small alternate rectangle apertures on the big or small identical rectangle aperture on the same straight line and several same straight lines are set on the common ruler main body, this two rows aperture be arranged in parallel, between two row's apertures a millimeter graduation mark is set.
