Abstract

The utility model discloses a Braille teaching aid, which comprises a Braille board and a Braille ball corresponding to the Braille board. A plurality of Braille grooves according to the Braille structure of six convexes is arranged on the Braille board. The Braille groove is cylindrical or hemispherical type. The depth of the Braille board is roughly half of the diameter of the Braille ball, the size of the Braille ball is suitable for placing in the Braille groove and half of the Braille ball is outwardly exposed to form the Braille convex. The utility model makes use of the Braille ball embedded in the Braille groove to form the Braille convex, which can increase the sense of touch and reduce the difficulty of teaching, and has very convenient writing, repeat using and avoids the waste of the paper.

Description

The braille teaching aid

Technical field

The utility model relates to a kind of special-purpose teaching aid of braille teaching usefulness.

Background technology

Braille is the special-purpose literal that uses for the dysopia personage, braille just, the general braille in the whole world is Frenchman Louis Blair invention now, it is a structure with the point of six projectioies, with the conversion of six some positions and the different formation brailles of distance, the braille of China is that 26 letters with the Chinese phonetic alphabet are 56 notes that the basis is transformed into braille, and these 56 notes are all represented with salient point, braille is that armrest removes to touch salient point and reads, be on special paper, to prick the salient point of coming out now with blind pen with braille, close and numerous, volume is very little again, touch and will produce fear of difficulty so begin to learn the blind person one of braille, even the blind person who has refuses to learn, especially the insensitive people of hand feeling, it is also of no avail to work hard.

The utility model content

For solving the problem that the blind person learns the braille difficulty, the purpose of this utility model is to provide a kind of rational in infrastructure, strong and repeatedly used braille teaching aid of touch sense.This braille teaching aid

For achieving the above object, the technical solution adopted in the utility model is:

A kind of braille teaching aid comprises braille plate and matching used braille ball, and the braille structure by six salient points on the braille plate offers many group braille grooves, and the size of braille ball can be put into the braille groove just, and has half to form the braille salient point to exposing outside.

Cylindrical or the semisphere of described braille groove.

The degree of depth of described braille groove is roughly half of braille bulb diameter.

Braille groove on the described braille plate has large, medium and small three kinds of font sizes, and braille ball size is corresponding with it.

The diameter of described braille groove is between 2.5mm～4.5mm, and sphere diameter is between 2.4mm～4.4mm.

Described braille ball is iron ball or steel ball.

Described braille plate is steel plate, iron plate, copper coin or plastic plate.

Described braille plate also disposes the bar magnet that is used for the taking-up of braille ball.

The utility model utilizes the braille ball to embed the braille groove and forms the braille salient point, thereby capable of being combinedly go out any braille, compare with blind traditional written form, have revolutionary change, the braille ball can be made various sizes such as large, medium and small as required, touch sense to strengthen, reduce teaching difficulty, write the also convenience of ten minutes, only need put into corresponding block position again and get final product with bar magnet with the sucking-off from the braille groove of braille ball, can use repeatedly, avoid the waste of paper.
