technical field

The invention relates to the related technical field of Braille teaching aids, in particular to an entry-level Braille teaching aid that is puncture-proof and easy to take and fix.

Background technique

Braille is a language for the visually impaired. With the development of society, some visually impaired children have some defects in their own vision, which will lead to great difficulties in the learning process. Writing is a very important process in the process of Braille. Therefore, in order to facilitate better learning and writing for visually impaired children, most of the entry-level Braille teaching aids are used. The entry-level Braille teaching aids can bring a lot of convenience to children's writing. , thereby improving the convenience of writing Braille for visually impaired children.

However, the current entry-level Braille teaching aids have the following problems:

1. The current entry-level Braille teaching aids themselves do not have certain protection and protection capabilities. They are easy to contact and rub with other objects in the process of carrying and storage, so that the writing board surface of the Braille teaching aids is damaged. It will greatly affect the service life of entry-level Braille teaching aids;

2. Most of the current entry-level Braille teaching aids are laid on the desktop for use, so it is easy to cause the visually impaired children to stoop when writing Braille because of their short height. development has a great impact;

3. When the current entry-level Braille teaching aids are used by visually impaired children, because the visually impaired children have certain defects in their own vision, it is easy to poke the visually impaired children's fingers in the process of writing with a Braille pen. This greatly increases the risk of injury to visually impaired children using this entry-level Braille teaching aid.

The holes 16 are abutted with each other, so that the movement stability of the guide rod 12 inside the through hole 16 can be ensured.

The protective cover plate 14 is symmetrically arranged with respect to the vertical center axis of the Braille teaching aid body 1, and the inner ends of the symmetrically distributed protective cover plates 14 are attached to each other, and the protective cover plate 14 is arranged in an “L”-shaped structure, and the protective cover plate 14 and the support base plate 20 are slidingly connected, and the support base plate 20 slides inside the protective cover plate 14 so as to facilitate the adjustment of the height of the Braille teaching aid body 1 .

Working principle: When using the entry-level Braille teaching aid that is anti-poke and easy to take and fix, firstly, as shown in Figure 1-10, when the body 1 of the Braille teaching aid is not used, the symmetrically distributed protective cover 14 can be used. Protect the writing board 2 on the body 1 of the Braille teaching aid, this time to avoid damage to the writing board 2 caused by friction between the writing board 2 and external objects. At the same time, when the normal writing operation is required, press and hold the guide on the handle 10. At one end of the rod 12, the guide rod 12 enters the inside of the adjustment rod 11, and the adjustment rod 11 is rotated. The rotation of the adjustment rod 11 can make the protective cover 14 open. As shown in Figure 5-8, when the protective cover 14 rotates to a certain angle , release the guide rod 12, the guide rod 12 is reset under the action of the built-in spring 13, and the reset guide rod 12 is re-inserted into the through hole 16, thereby realizing the fixed position of the protective cover 14, through the fixed protective cover 14 The body 1 of the Braille teaching aid can be propped up, so as to prevent the height of the body 1 of the Braille teaching aid from being low, resulting in the phenomenon of children stumbling during normal use. At the same time, as shown in Figures 1, 6 and 10, when the After the cover 14 is unfolded, the blocking block 7 is reset under the action of the compression spring 8, and the reset blocking block 7 can facilitate the visually impaired children's hand to move out of the range of the writing board 2, and the pull rod 18 is pulled to the right, and the The movement can disengage the left end from the socket 17 . At this time, the support base plate 20 is pushed downward. When the support base plate 20 moves to a suitable position, the pull rod 18 is released, and the pull rod 18 is reset under the action of the compression spring 19 After reset, the left end of the pull rod 18 re-enters the insertion slot 17 to realize the fixation of the position of the support substrate 20. Through the telescopic adjustment on the protective cover 14 of the support substrate 20, the Braille teaching aid body 1 can be satisfied by visually impaired children of different heights. high demand;

As shown in Figure 1-4, when writing is required, push the movable rod 5 to the outside of the placement slot 3, and the movable rod 5 can slide inside the limit block 4, and the Braille pen 6 can be released at this time. Fixed, the braille pen 6 can be used normally by taking it out from the inside of the placement slot 3, because the initial state of the pen needle 605 is stored inside the protective cover 601, so it is convenient for children to accidentally poke their fingers, and the process of marking and writing is required In the middle, hold the protective cover 601 to move it to an appropriate position, and move the push rod 602 to the left side of the protective cover 601. At this time, the movement of the push rod 602 can drive the bottom mounting plate 604 to perform synchronous movement. The movement can make the connecting telescopic block 606 move, and the movement of the connecting telescopic block 606 can make the clamping plate 607 slide inside the bottom mounting plate 604 under the action of the lateral connecting teeth 603, and the pen needle 605 extends out of the protective cover at this time. 601 can complete the normal writing and marking operation.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or to perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
