Ruler for preventing brush pigment from spilling over and polluting picture

Abstract

The invention discloses a ruler for preventing brush pigment from spilling over and polluting a picture, comprising a dividing ruler body. The ruler is characterized in that the lower part of one side with calibration marks of the dividing ruler body is provided with two convex semi-circles raised downwards; and two ends of the dividing ruler body opposite to the calibration marks are provided with a trolley respectively, meanwhile the middle position on the side is provided with a handle raised upwards for a painter to grasp and move. The ruler has the advantages of convenient picture movement and small impact on the picture. Furthermore, the ruler rim has a certain distance from the picture under a semispherical pad to prevent the drawing brush pigment from spilling over along the position of the ruler clinging to the picture and from polluting the picture when the painter paints the picture. The ruler can be particularly used as a guiding ruler for a drawing pen. Besides, a guiding groove with an arc-shaped section is arranged on the upper surface of the dividing ruler body along the length direction to ensure that the ruler is particularly matched with a bracket for assisting line drawing of a brush pen which is designed by the inventor separately.

Description

technical field [0001] The invention relates to a line-drawing tool for drawing, in particular to a line-drawing ruler for preventing paint from overflowing and polluting the picture. Background technique [0002] At present, in the work of manually drawing engineering drawings and forms, duckbill pens or needle pens or brushes are often used. But when drawing lines with duckbill pens, needle tube pens and especially writing brushes, the picture is often dirty due to the overflow of paint along the contact position of the ruler and the picture, which makes the drawing work produce many inconveniences. [0003] When drawing, if you want to draw straight lines with a drawing pen, you can draw the drawing pen against the edge of the scale, but it is difficult to solve the problem that the ink will overflow and pollute the picture along the ruler close to the picture during the drawing process. Chinese patents ZL 87208414 and ZL 87205985 disclose the roller-type drawing ruler. ...
