Description

Tool for composing symbols and drawing lines and tables

Technical Field

The invention relates to the field of teaching tools, in particular to a tool for typesetting symbols and drawing lines and tables.

Background

The symbols are closely related to languages, and a plurality of common symbols such as numbers, Chinese characters, letters and the like are generated in the development of human society; human use of symbols is typically one-dimensional, such as writing a word typically in units of rows; a typical example of two-dimensional use of symbols is a matrix in mathematics, which has extremely wide application in the fields of science, engineering, education, and the like; at present, writing and operation of the matrix can be processed by a computer, but at present, scenes of calculating the matrix through a human writing matrix and a human brain still exist in many fields, particularly the education field; in practical use of the matrix, some other symbols, such as numbers, letters, chinese characters, arithmetic or logic symbols, etc., may be added near the matrix elements for some purpose; it may also be necessary to draw lines to enclose the symbol elements, i.e. tabulate.

The existing tool for typesetting the symbol elements and setting the line and the table is generally a simple ruler, and the general ruler is difficult to typeset efficiently because the matrix has rows and columns, and can only solve the rows or the columns independently even if some rulers have parallel line-drawing grooves, and can not typeset the rows and the columns together; even though some technical schemes can solve the problem, the structure is more complex, and the use is also more inconvenient; especially when the rows and columns of the matrix are excessive, the efficiency of handwriting matrix typesetting and drawing lines and tables is low, and elements in the matrix are easy to deviate and are separated from the original positions; the light is cluttered and not beautiful, and the heavy causes the eyes to misread the elements in the matrix, thereby causing matrix operation errors.

Disclosure of Invention

The present invention is directed to solve the above problems, and therefore, to provide a tool for composing symbols and drawing a table, which can write symbols in a single row or single column arrangement or in a matrix arrangement, can draw a line and draw a table, and can be used in combination.

The invention solves the problems and adopts the technical scheme that:

the utility model provides a sign typesetting and setting-out tabulation instrument, includes the ruler body and sets up symbol frame, drawing line groove, scale mark on the ruler body, and the symbol frame is the array arrangement, and two adjacent symbol frame central distance equals, and the drawing line groove becomes row parallel equidistance and arranges the setting, and the symbol frame and the drawing line groove cross arrangement of same line set up, and the scale mark sets up on the intermediate line of two adjacent symbol frames of same line and perpendicular with two adjacent drawing line grooves.

Compared with the prior art, the invention adopting the technical scheme has the outstanding characteristics that:

the invention can write symbols in a single row and single column arrangement or in a matrix arrangement, can draw lines and make tables, can also be used in a combination way, has simple structure and convenient use, has high efficiency of handwriting matrix typesetting and drawing lines and tables, has the advantages of difficult deviation of symbols when in use, separation from the original positions, orderly matrix typesetting and drawing lines and tables, and can avoid matrix operation errors.

Preferably, the further technical scheme of the invention is as follows:

the drawing line groove is characterized by also comprising positioning mark holes, the positioning mark holes and the scale marks are in the same row and are arranged on the outer side of the drawing line groove to form a row, the positioning mark holes and the drawing line groove are in the same row and are arranged on the outer side of the drawing line groove to form a row, the distances between the adjacent positioning mark holes in the same row or column are equal, the positioning mark holes are adjacent to the drawing line groove, and the vertical distances between the positioning mark holes and the edge of the drawing line groove are equal; the positioning mark hole can be used for positioning when the tool is repeatedly used, and can also be used for positioning when the tool is rotated ninety degrees to draw another dimensional line.

The ruler body is provided with scale rulers which are arranged transversely and longitudinally; can be used to measure length.

Detailed Description

The invention will be better understood by the following description of embodiments thereof, but the applicant's specific embodiments are not intended to limit the invention to the particular embodiments shown, and any changes in the definition of parts or features and/or in the overall structure, not essential changes, are intended to define the scope of the invention.

Referring to fig. 1 to 3, the technical solution of the present invention is as follows:

a tool for composing and drawing symbols and a table comprises a ruler body 1, wherein scale rulers 6 which are transversely and longitudinally arranged are engraved on the ruler body 1, the scale rulers 6 are in centimeter units, the minimum scale unit is millimeter and can be used for measuring length, symbol frames 2, drawing grooves 3 and scale marks 4 are arranged on the ruler body 1, the symbol frames 2 are arranged in an array mode, eighteen symbol frames 2 are arranged in each row and twelve symbol frames 2 are arranged in each column, written symbols are limited in the set range by the symbol frames 2, the central distance between every two adjacent symbol frames 2 is 15mm, the drawing grooves 3 are arranged in parallel and equidistantly in rows, the central vertical distance between every two adjacent drawing grooves 3 is 15mm, the symbol frames 2 in the same row and the drawing grooves 3 are arranged in a crossed mode, the drawing grooves 3 are used for drawing and arranging lines, the scale marks 4 are respectively arranged on the middle lines of the two adjacent symbol frames 2 in the same row and are perpendicular to the two adjacent drawing grooves 3, the graduation marks 4 serve to limit the boundaries of the drawn row and column lines.
