Abstract

The utility model discloses one to prevent rubbing black tool ruler, comprise ruler body, the edge that ruler body contacts with pen is provided with the supporter be separated with ruler body lower limb by nib.The supporter be separated with ruler body lower limb by nib is provided with by the edge contacted with pen at ruler body, make when drawing is carried out, nib and ruler lower limb have a fixed gap, thus avoid ruler when moving, the figure finished is erased, cause unsharp phenomenon of drawing, improve the efficiency of drafting accuracy and drawing.

Description

Prevent rubbing black tool ruler

Technical field

The utility model belongs to fields of measurement, relates to dip stick structure, particularly relates to one and prevents rubbing black tool ruler.

Background technology

Traditional ruler, the T-square comprising architecture is all that 90 ° of angles are vertical with parallel rule edge, and mainly lower limb near paper, for architecture student, when drawing construction drawing, slightly because of carelessness, the not dry line of ink marker will be touched out, and affects paper clean level.Now commercially relatively good ruler is German red ring ruler, two little ribs are had under ruler, erect ruler, can avoid to a certain extent touching the line of ink marker, but due to the edge vertical section of its ruler or a plane, geographical perpendicular with ruler, slightly careless, ruler one tilts, and still can smear the line of ink marker, and ruler set up after have a fixed gap with paper, its shadow can disturb picture accuracy.

Summary of the invention

For above-mentioned defect or deficiency, the purpose of this utility model is that providing a kind of prevents rubbing black tool ruler.

For reaching above object, the technical solution of the utility model is:

Comprise ruler body, the edge that ruler body contacts with pen is provided with the supporter for being separated with ruler body lower limb by nib.

The cross section of described supporter is arcuate structure.

Described arcuate structure is outer male structure.

The cross section of described supporter is rectangular configuration or triangle, and the top edge of described rectangular configuration flushes with the top edge of an engagement edge and thickness is less than ruler body.

Described ruler body is provided with scale.

Described ruler body and supporter are structure as a whole.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model provides one to be prevented rubbing black tool ruler, the supporter be separated with ruler body lower limb by nib is provided with by the edge contacted with pen at ruler body, make when drawing is carried out, nib and ruler lower limb have a fixed gap, thus avoid ruler when moving, the figure finished is erased, causes unsharp phenomenon of drawing, improve the efficiency of drafting accuracy and drawing.

Accompanying drawing explanation

Fig. 1 is that the utility model is prevented rubbing black tool ruler structural representation one;

Fig. 2 is that the utility model is prevented rubbing black tool ruler structural representation two;

Fig. 3 is that the utility model is prevented rubbing black tool ruler structural representation three.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, the utility model provides one to be prevented rubbing black tool ruler, and comprise ruler body 1, the edge that ruler body 1 contacts with pen is provided with the supporter 2 for being separated with ruler body 1 lower limb by nib, and ruler body 1 and supporter 2 are structure as a whole.The cross section of described supporter 2 is arcuate structure, it is such as outer male structure, for gel ink pen, when nib contacts with ruler, owing to being provided with arc mechanism, therefore, the fuel-displaced part of nib forms space with ruler lower limb, ruler cannot be contacted with ink marks, thus avoid ruler when moving, to the pollution of ink marks.In order to measure conveniently, the surface of ruler body 1 is provided with scale.

As shown in Figure 2, the cross sectional shape of supporter 2 of the present utility model also can be rectangular configuration, and rectangular configuration flushes with the top edge of an engagement edge and thickness is less than ruler body, makes the fuel-displaced part of nib form space with ruler lower limb.As shown in Figure 3, the cross sectional shape of supporter 2 also can be square triangle.

The utility model provides one to be prevented rubbing black tool ruler, the supporter be separated with ruler body lower limb by nib is provided with by the edge contacted with pen at ruler body, make when drawing is carried out, nib and ruler lower limb have a fixed gap, solve common ruler when the line of ink marker of painter's journey construction drawing, the problem that ruler rubs the also not dry line of ink marker and touches out.Thus avoid the figure finished to erase, cause unsharp phenomenon of drawing, improve the efficiency of drafting accuracy and drawing, during Graphing of Engineering, no matter the whether vertical paper of needle tubing pen is drawn, and all can not to make dirty drawing during use by various angle.
