DETAILED DESCRIPTION

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] Example 1:

[0028] This embodiment describes the specific structure of a language teaching aid, please refer to the following for details. Figures 1-4 As shown, it includes a writing panel 1, multiple fan-shaped panels 4 (the writing panel 1 is used for drawing and displaying fun, and the multiple fan-shaped panels 4 are used for writing pinyin letters or Chinese characters for teaching) and a back panel 5 (connected to a magnetic blackboard). A control component passing through the interior of the writing panel 1 is set between the center of the writing panel 1 and the back panel 5. Multiple fan-shaped panels 4 are evenly spaced around the control component. The control component includes a disc 13. A ring 11 is integrally formed on the surface of the center of the disc 13. Multiple drive arms 8 are hinged on the surface of the edge of the disc 13. A shaft 15 is machined on the surface of the fan-shaped panel 4 near the control component.

[0029] The back plate 5 and the writing panel 1 are located on the front and back of the multiple fan-shaped panels 4, respectively. By connecting one end of the multiple drive arms 8 on the disc 13 to the outside of the shaft 15 on the surface of the multiple fan-shaped panels 4, when the control ring 11 rotates, the control component can control the multiple fan-shaped panels 4 to expand from the center to the surrounding areas or to move from the surrounding areas to the center.

[0030] Secondly, the back plate 5 has a storage tray groove 9 inside. By storing the disc 13 inside the storage tray groove 9, multiple fan-shaped panels 4 can be evenly spaced around the ring 11. After the bolt passes through the back plate 5, the disc 13, and the ring 11 and is threadedly connected to the writing panel 1, the writing panel 1 and the back plate 5 can be connected and fixed.

[0031] Furthermore, to prevent the writing panel 1 and the back panel 5 from being too close together, multiple fan-shaped panels 4 are clamped together to prevent them from moving, such as... Figure 3 As shown, a support column 12 is machined on the inner wall of the center of the storage tray 9. By fitting the disc 13 and the ring 11 onto the outside of the support column 12, and after the bolt passes through the inside of the back plate 5 and connects to the writing panel 1, the surface of one end of the support column 12 can be attached to the surface of the writing panel 1. With the support of the support column 12, the distance between the writing panel 1 and the back plate 5 can be controlled, and the ring 11 and the disc 13 can be positioned at the same time.

[0032] Furthermore, in order to control the path of the fan-shaped panel 4 as it moves between the writing panel 1 and the back panel 5 under the control of the control components, such as... Figure 3 and Figure 4As shown, the surface of the sector panel 4 on the side of the shaft 15 is machined with two limiting strips 7, the surface of the back plate 5 near the side of the sector panel 4 is provided with a plurality of limiting grooves 10, and the two limiting strips 7 are located on the two sides of the shaft 15. By slidingly connecting the limiting strips 7 on the sector panel 4 inside the limiting grooves 10, the sector panel 4 can be made to move along the opening of the limiting grooves 10 towards the activity.

[0033] The above design sets a plurality of sector panels 4 around the circular ring 11 at equal intervals between the writing panel 1 and the back plate 5, and articulates a plurality of drive arms 8 between the disc 13 on the back of the circular ring 11 and the plurality of sector panels 4. When the circular ring 11 is controlled to rotate outside the support column 12, the disc 13 can push and pull the sector panel 4 by means of the plurality of drive arms 8 (by sliding the limiting strips 7 inside the limiting grooves 10, providing a path for the sector panel 4 to move, making the sector panel 4) to expand around or close to the center between the writing panel 1 and the back plate 5.

[0034] Example 2:

[0035] Based on Example 1, as shown in Figure 3 and Figure 4 , this embodiment introduces the specific structure of the limiting groove 10. The surface of one side of the circular ring 11 is machined with two support rods 14, and one end of the two support rods 14 is pinned with a control disc 2 inside the writing panel 1.

[0036] Among them, the surface of the control disc 2 is attached to the surface of the writing panel 1. By connecting the control disc 2 with the two support rods 14, when the two support rods 14 are controlled to rotate on the surface of the writing panel 1, the circular ring 11 can be made to rotate outside the support column 12, and the disc 13 can push and pull the sector panel 4 by means of the plurality of drive arms 8, and control the sector panel 4 to expand around or close to the center between the writing panel 1 and the back plate 5.

[0037] Secondly, in order to control the range of rotation of the control disc 2 driving the two support rods 14, as shown in Figure 3 and 4 , two arc grooves 6 are machined inside the writing panel 1, and the two arc grooves 6 are symmetric about the center of the writing panel 1. By making the two support rods 14 respectively located inside the two arc grooves 6, the path of the support rod 14 can be controlled by means of the arc groove 6, so as to control the range of rotation of the control disc 2 driving the support rod 14.

[0038] Further, in order to facilitate the rotation of the control disc 2, as shown in Figure 1 , the edge of the control disc 2 is machined with four crescent notches 3. By arranging the four crescent notches 3 at equal intervals around the center of the control disc 2, it is convenient to provide control points for the operator.

[0039] The design sets the control disc 2 at the center of the surface of the writing panel 1, and the two support rods 14 on the side of the circular ring 11 are connected with the control disc 2 by pin connection, when the control disc 2 is controlled to rotate by the crescent slot 3 around the control disc 2, the control disc 2 can drive the support rod 14 to rotate, thus controlling the rotation of the circular ring 11 outside the support column 12, and the disc 13 pushes and pulls the fan-shaped panel 4 by the plurality of driving arms 8, so that the fan-shaped panel 4 is expanded to the periphery or close to the center between the writing panel 1 and the back plate 5, which is simple and convenient.

[0040] Finally, it should be noted that: obviously, the above examples are only examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can also be made. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
