Description

Drawing board for quickly drawing parallel lines

Technical Field

The utility model relates to a stationery technical field, concretely relates to draw parallel lines drawing board fast.

Background

When students write homework, the students often need to draw transverse lines of one line and one line to mark and distinguish the positions of multiple lines of characters when the students relate to writing composition, drawing board newspapers and writing application questions. At present, a common drawing method adopts a straight ruler, and lines are drawn along the straight ruler line by using a pen. Adopt a ruler to carry out the setting-out, have as follows inconvenience: firstly, the line interval is difficult to hold, and the multirow interval varies, and the influence is pleasing to the eye, and second many lines are not parallel well, draws askewly, and three moves the ruler line by line, and is inefficient, influences the operation speed.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a multirow line drawing board based on parallelogram principle can make things convenient for the student to draw the parallel lines drawing board fast of equidistance, parallel, pleasing to the eye multirow sharp fast high-efficiently.

The utility model provides a technical scheme that its technical problem adopted as follows:

a drawing board for quickly drawing parallel lines comprises a fixing plate, rivets, a line drawing ruler, a distance measuring ruler and fasteners; the fixed plate is the bar lamellar body, and quantity is two, and the setting-out ruler is the bar body structure, and quantity is 3-8, and parallel horizontal equidistance is arranged, and fix with rivet on the fixed plate is passed through at every setting-out ruler both ends, and the range finding ruler is the bar body structure, and fix with rivet in left side fixed plate and top setting-out ruler junction are passed through at the top, and the fastener is located right side fixed plate and bottom setting-out ruler junction.

The fastener is sleeved by a screw and a nut.

And length scales are marked on the distance measuring ruler.

The number of the line drawing rulers is 5.

Several line-drawing rulers with equal length are connected with the left and right fixed plates through rivets, and the fixed positions of the line-drawing rulers and the fixed plates can rotate;

on the fixing plate, the position intervals of a plurality of rivets are equal;

a plurality of line drawing rulers form a group of parallelograms through the fixing plates at the two sides.

The distance between the straight edges of the top line can be adjusted by adjusting the inclination degree of the parallelogram.

The distance measuring ruler is connected with one outermost leg of the parallelogram through a rivet. When the parallelogram shape is adjusted, the distance between the line drawing rulers can be measured through the distance measuring ruler.

The fastener is sleeved by a screw and a nut, and the parallelogram angle can be fixed after the fastener is screwed down, so that deformation is prevented; the parallelogram can be adjusted at will after being relaxed;

when a line is drawn, the distance between parallel lines can be quickly determined by the combined application of the line drawing ruler and the distance measuring ruler, and then the fastening pieces at the corners are screwed down to form a group of equidistant linear rulers. A group of equidistant parallel straight lines can be drawn quickly along each line drawing ruler by a pen.

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

the technology is that the distance between a group of rulers is rapidly adjusted according to the parallelogram principle; and the distance of the parallel line piece is quickly measured through the distance measuring ruler; the distance between the parallel lines can be fixed by the fastener to prevent the movement. The equipment is adopted to draw parallel lines, a group of measurable equidistant parallel line models can be quickly designed, the models are not easy to deform after being fastened, parallel lines with specified intervals can be conveniently and quickly drawn by using a pen, the equal line intervals are ensured, and all straight lines are parallel.
