Abstract
The utility model relates to a drawing ruler, particularly a drawing ruler which can display position. The utility model mainly solves the problem that drawing rulers used for teaching and drawing in the prior art can not display the position when used. So the exact positions of parallel lines, vertical lines and intersecting lines drawn in the drawing can not be ensured. A graphics drawn is distorted; the geometric effect is influenced. The utility model is characterized in that the circumference of the drawing ruler is provided with an annular transparent sealed tube. Disclosing solution is arranged in the sealed tube. The sealed tube is also provided with a graduation mark of positions of the disclosing solution. The utility model has the advantages of simple structure, convenient and rapid use, favorable effect of drawing, etc. The utility model is especially suitable for drawing on a blackboard in teaching, drawing in field measurement, construction work, etc.
Description
The utility model belongs to be write or drawing article, particularly a kind of drawing rule of energy display position.
Prior art is used ruler, set square, if do not use other drawing instrument, is difficult to draw parallel lines, vertical line and accurately draws intersecting lens, particularly field measurement, when imparting knowledge to students on the blackboard, need to draw, can only use ruler or set square, can't be borrowed in other drawing instrument, making drawing bring great difficulty, result is that draught smanship is poor, aliasing, influence graphical effect, increase user's labour intensity and the drawing time simultaneously.
The purpose of this utility model is, design a kind ofly can show the drawing rule position automatically, thereby when guaranteeing to draw, the geometrical relationship between every line realizes fast, novel drawing rule convenient, that accurately draw.
The purpose of this utility model is achieved in that and is provided with ring-type transparent sealing pipe on the surrounding edge of drawing rule, is provided with drawing rule position display liquid in the sealed tube, and sealed tube is provided with the demonstration liquid level and puts scale.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing 1 is the utility model triangle drawing rule schematic diagram.
Accompanying drawing 2 is accompanying drawing 1 cutaway view.
Accompanying drawing 3 is the utility model ruler drawing rule schematic diagram.
Accompanying drawing 4 is accompanying drawing 3 cutaway views.
Referring to accompanying drawing, in drawing rule 1 surrounding edge ring-type transparent sealing pipe 2, be filled with half and show liquid 3, during use, drawing rule 1 is answered in the leaving water plane and is used, when the drawing rule straight line that draws, according to the connector principle, 3 two liquid levels of demonstration liquid in the transparent sealing pipe 2 always are parallel to each other, and are highly equal, write down two liquid levels, scale on transparent sealing pipe 2, according to the liquid level that shows liquid 3, can on other position, accurately draw with the straight line parallel that draws, intersect and vertical straight line, the utility model shows that in order to make liquid 3 is obvious, show that liquid 3 adopts colour liquid, according to different environments for use, adopt different colors, this structure can be applicable to ruler, set square and other special-shaped chi.
The utlity model has simple in structurely, easy to use, cost is low, is specially adapted to teaching drawing on the blackboard, uses such as field measurement drawing and construction.
