Abstract
The utility model relates to a stationery, in particular to a ruled line drawing ruler, which adopts a rectangular thin sheet, at least two rectangular through holes are equidistantly arranged along the length direction of the rectangular thin sheet, and the upper surface of each rectangular through hole is provided with a corresponding column number scale; the width of the upper surface of each rectangular through hole is smaller than that of the lower surface of each rectangular through hole, namely, the lower surface of each rectangular through hole is provided with an anti-seepage chamfer; the periphery of the row ruler is also provided with an anti-seepage chamfer. The ruler is convenient for students and other workers to write daily homework and examination in the format Fan Shuxie so as to cultivate good homework writing habits and reduce workload of teachers during examination.
Description
Technical Field
The utility model relates to a stationery specifically is a ruled line drawing row chi.
Background
At present, workbooks and test papers printed in a student book have no grids in blank areas for students to write answering contents. If the answer writing process and answer are not drawn, the writing content is irregular, not easy to be normalized and not beautiful, the student works and the scroll are not neat, and the difficulty of review by teachers is increased. If the ruled line is drawn by hand by using a common ruler, additional time is spent, the efficiency is low, and the ruled line is difficult to position and is difficult to draw. The document with the publication number of CN209305199U discloses a graduated scale, a scale body is provided with two grid lines of English grid lines and Chinese grid lines, the upper surface and the lower surface of the scale body are both cambered surfaces to fasten a paper surface, so that the graduated scale has the functions of assisting in drawing a horizontal straight line vertical to the paper edge and drawing Chinese and English writing grid lines, but when the graduated scale is used, a straight line assistor is required to hook the edge of the paper surface to move from bottom to top, the graduated scale is inconvenient to use, and only a single grid line can be drawn at one time; in addition, when the graduated scale is used, because the paper surface is excessively attached to the graduated scale, ink in a pen usually pollutes the graduated scale and the paper surface due to a capillary phenomenon when the graduated scale is drawn.
Disclosure of Invention
Draw the difficulty that the check line exists to the homework book to and the problem that prior art's scale exists, the utility model provides a novel row's chi is drawn to check line.
The utility model discloses a ruled line drawing ruler, which is characterized in that the ruled line drawing ruler adopts a rectangular sheet, at least two rectangular through holes are equidistantly arranged along the length direction of the rectangular sheet, and the upper surface of each rectangular through hole is provided with a corresponding digital scale; the width of the upper surface of each rectangular through hole is smaller than that of the lower surface of each rectangular through hole, namely, the lower surface of each rectangular through hole is provided with an anti-seepage chamfer.
As the best mode of the invention, the lower surface of the peripheral edge in the width direction of the row ruler is provided with the anti-seepage chamfer which is used for preventing ink and printing ink from seeping when drawing the grid lines and is convenient for picking up the row ruler after the operation is finished.
Furthermore, the anti-seepage chamfer adopts a right-angle chamfer or an inclined chamfer and is used for preventing ink and printing ink from seeping when the grid line is drawn.
As the best implementation mode of the invention, the upper surface of the row ruler is provided with a plurality of groups of column separation lines along the length direction of the rectangular through hole, the column separation lines are perpendicular to the rectangular through hole, and the column separation lines divide the rectangular through hole into two, three or four sections respectively, so that a user can conveniently separate the drawn line segments.
The ruled line drawing ruler of the utility model is suitable for students, is convenient for the students to use in the specification Fan Shuxie format during daily homework and examination so as to cultivate the good homework writing habit of the students and reduce the workload of teachers during reading; the ruler has the advantages of strong practicability, simple manufacture, controllable cost and worth of popularization.

Detailed Description
Example 1: the ruled line drawing ruler disclosed by the embodiment adopts a rectangular sheet, six rectangular through holes 1 are arranged along the length direction of the rectangular sheet at equal intervals, and the upper surface of each rectangular through hole 1 is provided with a corresponding digital scale; the width of the upper surface of each rectangular through hole 1 is smaller than that of the lower surface of each rectangular through hole, namely, the lower surface of each rectangular through hole 1 is provided with an anti-seepage chamfer which is a right-angle chamfer.
The ruled line drawing ruler can adopt various specifications, and manufacturers can manufacture lines with the distance of 10mm, 9mm, 8mm, 7mm, 6mm and the like for students to select. If the width of the upper surface of the rectangular through hole 1 is a, the line spacing of the rectangular through hole 1 is b, the width of the row ruler is c, the length of the rectangular through hole 1 is e, the distance between the rectangular through hole 1 and the edge of the row ruler is f, and the length of the row ruler is g, the row ruler can be prepared according to the following dimensions:
according to actual needs, the inventor provides a set of row rulers with different space sizes (see the line space b of the rectangular through holes 1 and the width c of the row rulers in a specification table) for a user to select. The problem that grid lines are required to be drawn at different intervals in different types of operations such as mathematics, chinese, calligraphy, tabulation and the like is solved, and the problem that grid lines at different intervals need to be drawn due to different ages and the like in the same type of operations is solved: the row ruler with larger inter-row distance is mainly suitable for students in the lower grades of primary schools; the row ruler with smaller row distance is mainly suitable for students and workers in high grades, junior high schools and high schools of primary schools.
The lower surfaces of the edges of the periphery of the row ruler and the lower surface of the rectangular through hole 1 are provided with anti-seepage chamfers 2, and the anti-seepage chamfers 2 are right-angle chamfers.
The user can draw the whole parallel grid line along the exercise book or the scroll, and the writing tool is suitable for writing in the whole line of block operation.
Meanwhile, column separation lines 3 are arranged on the upper surface of the row ruler, and the column separation lines 3 are respectively set as red solid lines, blue solid lines and red dotted lines.
The red solid line is used for plotting: parallel ruled lines at 1/2 of the book or the scroll are suitable for half-row block writing;
the blue solid line is used to plot: parallel ruled lines at 1/3 of the book or the scroll are suitable for 1/3 line block operation writing;
the red dashed line is used to plot: parallel ruled lines at 1/4 position along the exercise book or the scroll are suitable for 1/4 row block operation writing;
according to different requirements of one-column, two-column and three-column operation, column separation lines of different column separation operations are provided, and the problem of repeatedly calculating the width of an operation column and the distance between columns is solved.
The utility model provides a platoon size is only partial embodiment of this invention, and the user can customize each specification of platoon size according to actual need, and the specification of platoon size is not limited to the above-mentioned list, as long as the structure of the invention content part of this invention has been adopted, all should fall into the protection scope of this invention.
