Abstract

The utility model discloses a dividing ruler for preventing ink from contaminating paper, which is machined with a small groove with the length corresponding to the length of a ruler, the width of 1-2mm and the depth 0.2-0.5mm on the back of the ruler body at one side of scales. When marking with a pen or a sign pen, due to the groove on the edge in the back of the ruler, the edge in the front of the ruler is not directly contacted with paper on one side and the edge in the back of the ruler is not directly contacted with pen point on the other side. Redundant ink is left on the edge of the ruler but does not contaminate paper. After marking, the ruler is removed and the redundant ink on the ruler is wiped away.

Description

Prevent the rule of inkiness paper

Technical field

The utility model relates to drawing instrument, the rule of the usefulness of especially ruling.

Background technology

Rule is the scoring tool that the student uses always, and set square, ruler, T-square etc. are arranged, and structure generally all is to be marked with scale at the ruler body, and the time spent is placed on ruler on the paper, just can rule along the ruler edge.Though it provides convenience for student's line, but deficiency is, when with pen or signature pen line, pen or signature pen nib have unnecessary ink, these unnecessary inks can be stained with on the ruler edge, because the ruler back side closely contacts with paper, these unnecessary inks will flow into paper along the ruler back side and pollute paper, influence the attractive in appearance of the bar of ruling.

Inkiness paper in order to prevent to rule, the student who has is when line, often adopt two ruler stacks to use, during use, allow top ruler and below be close to ruler parallel misalignment stack on the paper, promptly allow following ruler leave the nib certain distance, only allow stack superincumbent ruler contact nib, even there is ink also can not be stained with on the following ruler like this, prevented that ink is stained with on the paper.Though solved problem, use cumbersome, and if do not notice that slightly two rulers will be moved, and influence the picture accuracy.

At present, occurred a kind of ruler on the market, it is that the inclined-plane is arranged at scale position, ruler front, and this ruler can prevent chi edge friction nib; In order to prevent nib inkiness paper, the student who has is its usefulness conversely, and this has alleviated the phenomenon of nib inkiness paper to a certain extent, but can not tackle the problem at its root, and conversely with causing reading not directly perceived.

Summary of the invention

The nib ink pollutes the technical problem of paper easily when using in order to overcome existing rule, and the utility model provides a kind of rule that can prevent the inkiness paper.

For achieving the above object, the technical scheme that the utility model is taked is: it comprises the rule body, it is characterized in that, the back side of described ruler body scale one side is processed with length and ruler adapts, the sulculus of wide 1-2mm, dark 0.2-0.5mm.

The utility model has the advantages that: when the time with pen or signature pen line, because the ruler dorsal edge has groove, during line, the ruler front edge does not directly contact with paper on the one hand, and the ruler dorsal edge does not directly contact with nib yet on the other hand, even unnecessary ink can be stayed on the ruler edge, paper can not depollute more yet, after having drawn line, remove ruler, wipe ink unnecessary on the ruler and get final product.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model, is example with the ruler among the figure;

Fig. 2 is the left view of Fig. 1.

Among the figure: 1-rule body, 2-sulculus.

The specific embodiment

As illustrated in fig. 1 and 2, the utility model is to be processed with length at the back side of scale one side of rule body 1 and ruler adapts, the sulculus 2 (scale does not draw among the figure) of wide 1-2mm, dark 0.2-0.5mm.When the production and processing ruler, the sulculus of being a wide long 1-2mm, dark 0.2-0.5mm along the bottom (side that contacts with paper) at ruler scale edge gets final product.

During line, the ruler front end just can directly not contact with paper.

Claims (1)

1. rule that prevents the inkiness paper, it comprises the rule body, it is characterized in that, the back side of described ruler body scale one side is processed with length and ruler adapts, the sulculus of wide 1-2mm, dark 0.2-0.5mm.
