Abstract
The utility model discloses a Braille measuring tape, which comprises a tape head, a tape, and a shell. One side of the tape is marked with length scales and the other side is provided with gaps based on the length scales. The lengths of the gaps for three length scales of cm, dm and m are different. The length of the gaps for the cm length scale is the shortest and the length of the gaps for the m length scale is the longest. The Braille measuring tape has the advantages of convenience, practicability, convenient operation and the like.
Description
Technical field
The utility model relates to a kind of survey instrument, especially a kind of ruler.
Background technology
As everyone knows, ruler is dimensional measuring instrument the most frequently used in people's study and work.But present ruler is only suitable for the normal person and uses, and for the blind person, can't use ruler to carry out linear measure longimetry, and is very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of braille tape measure reasonable in design, convenient and practical, easy and simple to handle.
The utility model comprises chi head, chi bar and shell, a limit marking length scale of chi bar, and another limit is according to length scale processing gap, and the gap that is in three kinds of length scales of centimetre, decimeter, meter is uneven in length.The gap length at centimeter scale place is the shortest, and the gap length at Mi Changdu scale place is the longest.
When the normal person used, the user held the chi head, pulled out the chi bar from shell, measured length by the length scale of chi bar surface marking, the normal function of performance ruler.When the blind person uses, after extracting the chi bar out, the chi bar is pressed close to object to be measured, then grope the gap on recording rule bar surface along the chi head to the other end with hand, carry out length computation by each gap, thereby draw the length of object under test.
Compared with the prior art, the beneficial effects of the utility model are: convenient and practical, operation facility, use when helping the blind person to measure length.
Description of drawingsFig. 1 is spatial structure sketch of the present utility model.
EmbodimentIn spatial structure sketch of the present utility model shown in Figure 1, comprise chi head 1, chi bar 2 and shell 3, a limit marking length scale of chi bar, another limit be according to length scale processing gap 4, and the gap that is in three kinds of length scales of centimetre, decimeter, meter is uneven in length.The gap length at centimeter scale place is the shortest, and the gap length at Mi Changdu scale place is the longest.
