Description

Portable braille board

Technical Field

The utility model relates to a braille board equipment field especially relates to a portable braille board.

Background

As is known, the blind people can smoothly complete the writing process only by using a certain tool when writing, and the writing process is extremely difficult. Some writing tools for the blind have been provided on the market, but the styles and forms are very similar; the common braille writing board has the problems of large volume, heavy weight and inconvenience for carrying in use, and the use space is limited to a certain extent. Meanwhile, the product is not beautiful enough and has certain potential safety hazard

The braille writing board disclosed in the chinese invention patent CN 101477761a is characterized by comprising a board body and a plurality of dot position holes which are arranged on the board body and have the same square and the same dot position layout as braille, a plurality of salient point elements which are limited in the dot position holes and movably matched with the dot position holes up and down, and a braille pen which is magnetically matched with the salient point elements. When the bump element is in an initial state or a standby state in the point position hole, the height of the top of the bump element is lower than the opening plane of the corresponding point position hole; when the bump element receives the magnetic attraction of blind writing brush and during the upward movement, receives behind the limiting displacement in point position hole, cancel the magnetic force effect of blind writing brush, and after the bump element received self action of gravity to fall back, when self is in the stress balance and is fixed a position in the opening part in corresponding point position hole static, the top height of bump element is just higher than the opening plane in corresponding point position hole, promptly the bump of braille has been acted as at the top of bump element to the braille of a plurality of square units that corresponding combination write.

Therefore, a braille writing board which is small in size and convenient to carry is urgently needed at present.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The first embodiment,

The structure of the portable braille tablet of the present embodiment includes, as shown in fig. 1 to 8: the braille layer 2, the sliding layer 3 and the rotating shaft 4 are arranged on the grid layer 1;

the grid layer 1, the braille layer 2 and the sliding layer 3 are sequentially overlapped;

the rotating shaft 4 penetrates through the grid layer 1, the braille layer 2 and the sliding layer 3 and is used for connecting the grid layer 1, the braille layer 2 and the sliding layer 3;

the grid layer 1, the braille layer 2 and the sliding layer 3 can respectively rotate by taking the rotating shaft 4 as the center of a circle;

the rotary shaft 4 can make reciprocating sliding on the sliding layer 3 for moving the position of the mesh layer 1 and the braille layer 2 on the sliding layer 3.

Two lines of grid frames 11 are arranged on the grid layer 1, and the grid frames 11 penetrate through the grid layer 1 and are used for limiting the writing area of the braille.

The braille layer 2 is provided with two lines of braille squares 21, and the single lattice frame 11 can be fitted over the single braille square 21.

The sliding layer 3 is provided with a plurality of sliding slots 31, two ends of each sliding slot 31 are provided with protrusions 32, and the protrusions 32 are used for limiting the sliding position of the rotating shaft 4 on the grid layer 1.

When writing the braille, with the perpendicular position of sliding layer 3 rotatory to and net layer 1 and braille layer 2, net layer 1 and braille layer 2 overlap and put on writing paper, grid frame 11 just in time is located the braille square 21 directly over like this, through the cooperation of blind writing pen and braille square, write out the braille on writing paper, single grid frame 11 prescribes the writing scope of single braille square 21, make the writing of braille more normal, stir rotation axis 4 downwards when two lines of braille squares 21 on braille layer 2 are all written to the full, make rotation axis 4 get into second slip fluting 31 in, be used for adjusting down net layer 1 and braille layer 2 and be used for continuing to write, and because slip fluting 31 both ends all are equipped with protruding 32 and make rotation axis 4 just in time get into slip fluting 31 in, the position of net layer 1 and braille layer 2 removal at every turn has been prescribed a limit.

When writing is finished, the grid layer 1, the braille layer 2 and the sliding layer 3 are folded into a whole only by rotating the rotating shaft 4, so that the braille writing board is smaller in size and convenient to carry.

Example II,

Because the blind person can't see the position dislocation of net layer 1 and braille layer 2, consequently can't in time adjust when writing, also brought the trouble for writing, consequently in order to prevent that net layer 1 and braille layer 2 from misplacing, can set up magnet 5 on net layer 1 and braille layer 2, make net layer 1 and braille layer 2 adsorb each other, can effectually prevent net layer 1 and braille layer 2 dislocation when writing the braille like this.

The braille square is a braille system that simple convex points replace Latin letters, so that the surnames of the users are internationally used as the international common names of the global braille characters, and the braille is called as 'Boolean'. The braille is a character symbol which is specially designed for the blind and realizes touch reading and writing through tactile perception, is also called braille or convex character, the international universal braille is composed of six convex round points which are used as a basic structure and divided into a left row and a right row, each row of three points is a structural principle of 2 multiplied by 3, the structural principle is called 1 point, 2 point and 3 point from the left side to the top, the structural principle is called 4 point, 5 point and 6 point from the right side to the top, the structural principle is called point positions, point positions on the paper are convex, some point positions are not convex, 63 changes are formed, namely 63 point symbols, and each point symbol unit is called square for short.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
