Abstract

The invention relates to a mapping tool, and relates to a ruler used for blind people and ordinary people. The ruler comprises a ruler body, which is in the shape of a T. The left side of the ruler body is a pen stopping plate, and two sides of the ruler body are provided with concave grooves and wave-shaped segments along the length direction. The grooves are divided into centimeter grooves and millimeter grooves, and the centimeter grooves are one millimeter lower than the ruler body, and the millimeter grooves are one millimeter groove lower than the centimeter grooves, and because of the one-millimeter height difference, the pen can be supported, when the pen moves along the grooves. The deepest parts of the millimeter grooves are one millimeter away from the edge of the ruler body, and the object is to guarantee the smooth drawing. Every wave-shaped segment is one centimeter higher than the previous segment, and the Braille numerals are correspondingly disposed on the segments, and then the rough and fast measurement can be carried out conveniently. The ruler body is provided with the centimeter scales, the millimeter scales, the Braille numerals, and the Arabic numerals, and the centimeter scales and the Braille numerals are protruded to facilitate the hand touching of the blind people. The ruler provided by the invention is advantageous in that the accurate measurement and mapping of the blind people can be realized without affecting the use of the ordinary people; the use is simple, and the measurement is accurate.

Description

A kind of blind person, ordinary person's two-purpose ruler
Technical field:
The present invention relates to surveying and mapping tool field, be specifically related to a kind of blind person, ordinary person's two-purpose ruler.
Background technology:
Little for the ruler of blind person on the market, have also simply simple plus braille numeral, do not have the effect of precisely mapping.And can accurately measure, draw almost without.
Summary of the invention:
It is an object of the invention to overcome disadvantages mentioned above, make blind person the same with ordinary person, it is possible to measure accurately, draw, length can also be measured roughly rapidly simultaneously.
For solving technical barrier, the technical support adopted is: providing a kind of blind person, ordinary person's two-purpose ruler, including blade, blade is "T"-shaped.For a gear plate on the left of blade, it is provided with groove and wave section along its length in blade both sides.
Described groove is divided into centimetre groove and millimeter groove, and centimetre groove is shorter one millimeter than blade, and millimeter groove is shorter than centimetre groove one millimeter, one millimeter away from blade edge be of millimeter groove bosom.
The each segment length of described wave section one centimetre, each section all has corresponding braille numeral.
Described blade has centimeter scale, millimeter scale, braille numeral, Ah position's uncle's numeral.
Described centimeter scale and braille numeral are all protruding.
It is an advantage of the invention that neither affecting ordinary person uses, and can allow again blind person measure accurately, draw.Usage is simple, and mapping is precisely.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is the partial enlarged drawing of the present embodiment;
In figure: 1, blade;2, a gear plate;3, centimetre groove;4, millimeter groove;5, Arabic numerals;6, braille numeral;7, centimeter scale;8, millimeter scale;9, wave section.
Detailed description of the invention:
Below in conjunction with accompanying drawing and instantiation, it is further elucidated with the present invention.
Refer to shown in Fig. 1, be for present configuration schematic diagram.Thering is provided a kind of blind person, ordinary person's two-purpose ruler, including blade 1, blade 1 is "T"-shaped.For a gear plate 2 on the left of blade 1, it is provided with groove and wave section 9 along its length in blade 1 both sides.Groove is divided into centimetre groove 3 and millimeter groove 4, centimetre groove 3 is shorter than blade 1 one millimeter, millimeter groove 4 is shorter than centimetre groove 3 one millimeter, short one millimeter in order that allow pen along groove move time to some extent according to support, one millimeter away from blade 1 edge be of groove 4 bosom of millimeter, the purpose that isolated edge is a millimeter is that setting-out is smooth.The each segment length of wave section 9 one centimetre, each section all has corresponding braille numeral 6, measures rapidly roughly to facilitate.Blade 1 has centimeter scale 7, millimeter scale 8, braille numeral 6, Ah position's uncle's numeral 5, and centimeter scale 7 and braille numeral 6 are all protruding, facilitate blind person's hands to touch perception.
Time specifically used, first method is: touches braille numeral 6 by hands and finds the cms oneself thinking picture, pen is positioned in centimetre groove 3 of correspondence by the centimeter scale 7 then touching correspondence, move forward to millimeter groove 4 again, move right along millimeter groove 4, gone out to think the millimeter of picture by the millimeter groove 4 number meter of process, further along the millimeter groove 4 counted out, pen is removed forward, finally pen is moved left to a gear plate 2 and can draw the precise length wanted.
Second method is: touch braille numeral 6 perception " 0 " scale by hands, pen is positioned over centimetre grooved area that " 0 " scale is corresponding, then hold pen to move right, the cms oneself thinking picture is gone out by centimetre groove 3 number meter of process, millimeter groove 4 is moved forward to then along centimetre groove 3 counted out, move right along millimeter groove 4, gone out to think the millimeter of picture by the millimeter groove 4 number meter of process, further along the millimeter groove 4 counted out, pen is moved upward out, finally pen is moved left to a gear plate 2 and can draw the precise length wanted.
If draw wave or rough Measuring Object size rapidly, then by wave section 9.
Certainly, illustrated above it is only better embodiment of the present invention, not limits the use scope of the present invention with this, therefore, every in the principle of the invention, make equivalence change and should be included in protection scope of the present invention.
