Description

Technical Field

[0001] The utility model relates to the technical field of children's teaching aids, in particular to a circular pancake-shaped reusable children's teaching aid. Background Art

[0002] After a newborn is born, he or she will naturally become the baby of the family. In addition to the basic care of food, clothing, housing and transportation, parents will also buy some teaching aids to cultivate the child's basic cognition. Children's teaching aids need to meet many requirements, the most basic of which is that the cognitive training program is reasonable and safe to use. For example, common children's teaching aids are stickers with images of various real-world objects, such as plants, animals, fruits and vegetables, and transportation tools, etc. Through repeated viewing and proper education from parents, children's basic cognition of the world can be cultivated. Although this can achieve certain training effects, it often happens that parents will not replace the pictures after they are pasted. The number of objects that children can recognize is limited, and it is easy to damage the wall where the stickers are pasted when they are replaced. Based on this situation, how to increase the number of real-world objects that children can recognize through children's teaching aids as much as possible, while avoiding the damage that the children's teaching aids may cause to their environment, is becoming an increasingly urgent problem that relevant technical personnel need to solve.

The initial purchase quantity can already meet the needs at that time. Parents can also replace and update the pictures at any time, thereby effectively increasing the number of real-world objects that children can recognize through the teaching aids;

[0013] 2. In addition to changing the pictures, parents can also replace the entire set of connectors, which effectively ensures the flexibility of the use of this teaching aid. The semicircular design of the edge of the horizontal plate and the quarter-circular design on both sides of the lower part of the main body effectively avoid bumps on parents and children, thereby effectively ensuring the safety of the use of this teaching aid;

[0023] Furthermore, a sealing gasket 2 is fixedly disposed on the upper portion of the main body 1 , and the lower surface of the inner recess 12 is in contact with the upper surface of the sealing gasket 2 .

[0024] Furthermore, a lower groove is provided at the center of the lower part of the main body 1, a magnet 6 is provided inside the lower groove, a lower cover 9 is provided directly below the magnet 6, the magnet 6 is snap-connected with the lower cover 9, bolts 7 are equidistantly arranged in a ring at the center of the lower cover 9, the bolts 7 are threadedly connected to the lower cover 9 and the main body 1, and the outer wall of the lower cover 9 is in contact with the inner wall of the lower groove.

[0025] Furthermore, the magnet 6 is in the shape of a ring.

[0026] Furthermore, a mounting seat 17 is fixedly provided at the center of the lower portion of the lower cover 9 , and a hanging ring 8 is fixedly provided at the center of the lower portion of the mounting seat 17 .

[0027] Furthermore, the edge of the horizontal plate 15 extends out of the inner recess 12, and the cross-sectional shape of the portion of the horizontal plate 15 extending out of the inner recess 12 is semicircular, and the cross-sectional shapes of both sides of the lower portion of the main body 1 are quarter-circular.

[0028] The working principle of the circular pancake-shaped reusable children's teaching aid of the utility model is as follows: by default, the teaching aid exists as an independent and complete whole, and matching pictures printed with real-world objects such as plants, animals, fruits and vegetables, and transportation tools are stably placed inside the limiting ring 13. Parents purchase a suitable set of the teaching aid based on the child's age and current cognitive level, and adsorb it on an iron plate through a magnet 6. The child can learn the content on the picture through a transparent horizontal plate 15, thereby expanding cognition. After learning a set of content, parents can purchase pictures suitable for the next stage of learning, remove the teaching aid from the iron plate and take it off. The upper cover 4 is used to take out the original picture, and the new picture is stably placed in the limiting ring 13, the upper cover 4 is reset, and the teaching aid with the replaced picture is re-adsorbed on the iron plate. The limiting ring 13 keeps the picture stable, and the anti-slip pad 11 keeps the vertical plate 16 and the upper cover 4 stable as a whole. After completing the replacement of the whole set of pictures, the original pictures are collected in one place to avoid scattering everywhere, so as to encourage children to further learn through this teaching aid. Parents can also choose to buy a new set of middle connectors 3 with new pictures built in, and directly replace the original middle connector 3. In addition to adsorption, a thin rope can also be tied to the hanging ring 8, and then the teaching aid can be hung in a suitable position to increase the viewing experience.

[0029] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
