CN202528694U - Drawing scale plate with board provided with salient points - Google Patents

Abstract

The utility model discloses a novel technical scheme of drawing scale plates, and provides a drawing scale plate with a board provided with salient points. The drawing scale plate with the board provided with the salient points can prevent paper from being stained by spreading ink, and comprises a scale plate, and the salient points which are evenly distributed are processed on a board of the scale plate. The drawing scale plate with the board provided with the salient points is suitable for drawing scale plates.

Description

The drawing rule plate of band salient point on the plate face

Technical field:

The utility model belongs to the stationery field, specifically is meant the drawing rule plate.

Background technology:

The drawing rule plate is important drawing instrument, in the mapping operation of non-computer, is indispensable, and it generally comprises ruler, set square, camber line chi, Pattern plate ruler etc.; Material has plastics or stainless steel; The common arris of the chi plate of any moulding or material all is rectangular shape, and this shape and structure is simpler, and is with low cost; But the chi plate of this structure in use often is prone to the phenomenon of the diffusing stained paper of ink of spreading and sinking in; Because the drawing than standard generally will be used ink pen, the crest line of the chi plate of the rectangular shape of this arris is inevitable to contact with drawing, when nib during along chi limit line drawing the ink on the nib not only can be coated onto and also can be stained with on the paper on the lower edgeline that is coated onto with the contacted chi plate of drawing; The effect of capillarity just can make the very fast diffusing paper of spreading and sinking in of ink, causes a lot of troubles even scraps whole figure; If can the seamed edge pad of chi plate be risen and raise; Nib contacts with the chi limit but chi limit or chi arris line can directly not contact with the drawing paper again during though make to draw, and the phenomenon of the stained paper of ink has been loose in having spread and sunk in of then also can eliminating this chi plate regular meeting occurs when drawing.

The utility model content:

The purpose of the utility model is the new technical scheme that a kind of drawing rule plate is provided, and it can address the above problem effectively.

The technical scheme of the utility model is achieved in that it comprises the chi plate, is processed with equally distributed salient point on the plate face of said chi plate.

Though the beneficial effect of the utility model is that nib contacts with the chi limit but chi limit or chi arris line can directly not contact with the drawing paper again when drawing, regular meeting occurs, and spread and sink in the loose phenomenon of the stained paper of ink has been eliminated fully.

Description of drawings:

Fig. 1 is that common chi arris line is rectangular-shaped chi plate partial sectional view.

Fig. 2 is the cutaway view of the drawing rule plate of band salient point on the plate face.

Among each figure, 1 is the chi plate, and 2 is salient point, and 3 is the right angle crest line, and 4 is the chi limit.

The specific embodiment:

As shown in Figure 1; The partial sectional view of the chi plate of the common rectangular shape of chi arris; Can see that from figure chi arris line is that right angle crest line 3 is the right angle, crest line and chi limit 4 are on the same facade, during the drawing pen line drawing with when chi limit 4 contacts also with contacted with the contacted crest line 3 of drawing paper; This just causes sticking of ink and crest line, and Here it is produces the basic reason of the stained paper phenomenon of ink of loosing of spreading and sinking in.As shown in Figure 2; Uniform processing goes out a plurality of salient points 2 on the plate face of chi plate 1; The right angle crest line 3 of chi plate 1 has just been filled up to raise no longer with whole chi plate and has directly been contacted with the drawing paper, has loose the phenomenon of the stained paper of ink thereby eliminated this chi plate having spread and sunk in of regular meeting's appearance when drawing fully.

Claims (1)

1. the drawing rule plate of band salient point on the plate face, it comprises the chi plate, it is characterized in that being processed with equally distributed salient point on the plate face of chi plate.
