Abstract
The utility model relates to a Braille tape which shares the same shape with common tapelines. Blind persons who use the Braille tapeline can feel the length of the object due to the special raised graduation marks and Braille figures on the narrow scale of the tape.
Description
Technical field
The utility model relates to a kind of measurement measurer, is applicable to measure the circle chi that length has braille.
Technical background
On the market measurement length instrument miscellaneous is arranged now, as circle chi, ruler, slide calliper rule etc.They can let us measure the length of the object of various our required measurements easily.But in a single day they arrived in blind person's hand, just had no the ample scope for abilities, and state is top institute target scale for the blind person cannot see.
Summary of the invention
The purpose of this utility model is made the scale mark of special projection and the circle chi of braille numeral on a kind of chi bar, make things convenient for the blind person normal person equally to measure length, knows how long object at one's side has.
The purpose of this utility model is achieved in that 1. 1 kinds of braille circle chis, comprises circle chi housing, chi bar and clockwork spring composition, it is characterized in that every interval is an outstanding numeral for 1 decimeter on the chi bar, only represents with 1 dot for per 1 centimetre.The blind person is by the sharp sense of touch of finger, the length of object that perception is surveyed.During measurement, earlier touch out the measurement thing with hand and do not hold to the nearest projection numeral of initiating terminal, and then touch out this numeral and measure thing and do not held what dots, the length of thing is measured in both additions exactly.
Advantage of the present utility model:
The utility model is a kind of braille circle chi.External form is the same with common circle chi, just because the scale mark and the braille numeral of special projection are arranged on the chi bar of circle chi, can make blind person user, clearly perceives the length of the object of surveying.

Specific embodiment
Embodiment
When to use this circle chi to measure a segment length be 23 centimetres object, pull out circle chi chi bar 1 earlier, circle chi bar head is aimed at object one end, stretches along object then and encloses chi, when object is not held, with the scale on the hand touch appropriate section chi bar 1, return to circle chi head along chi bar 1 earlier and touch, touch a nearest projection numeral 4 and be arabic numeral 2, promptly 2 decimeters, and then calculate, do not held 3 protruding points 3 from this numeral to object, be 3 centimetres.Both additions at last, the measurement numeral that obtains is 23 centimetres.
Claims (2)
1. braille circle chi comprises that circle chi housing, chi bar and clockwork spring form, and it is characterized in that enclosing scale mark and braille numeral that projection is arranged on the chi bar of chi.
2. a kind of braille circle chi according to claim 1 is characterized in that, every interval is an outstanding arabic numeral numeral for 1 decimeter on the chi bar, only represents with 1 dot for per 1 centimetre.
