Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example: A turntable for teaching English grammar tenses, such as... Figure 1-4As shown, the system includes a chassis 1, a support column 2, a middle plate 6, a display panel 7, a turntable 8, a pin 9, a limiting component 10, and a fixing bolt 11. The support column 2 is rotatably connected to the chassis 1, and the middle plate 6 is fixedly connected to the other end of the support column 2. The display panel 7 is hinged to one end of the middle plate 6, and the limiting components 10 are fixedly connected to both sides of the display panel 7. The fixing bolts 11 are threadedly connected to both sides of the middle plate 6, and the middle plate 6 is connected to the limiting components 10 through the fixing bolts 11. The display panel 7 has a groove, and the turntable 8 is rotatably connected in the groove. The upper and lower ends of the turntable 8 and the upper end of the display panel 7 have positioning holes that are aligned with the same straight line, and the pin 9 is inserted into the positioning holes.

[0020] like Figure 1-4 As shown, rotating shafts 804 are fixedly connected to both sides of the large disk 801. The large disk 801 is rotatably connected to the display board 7 through the rotating shafts 804. A small disk 802 is rotatably connected to the large disk 801, and a pointer 803 is rotatably connected to the small disk 802. During teaching, students rotate the pointer 803 to select the word on the small disk 802, and then find the corresponding tense variant on the large disk 801. This allows for deeper participation in the class and enhances learning initiative and understanding and memorization of grammar knowledge.

[0021] like Figure 1-4 As shown, a driven wheel 3 is fixedly connected to the support column 2, and a motor 5 is installed on the chassis 1 near the support column 2. A driving wheel 4 is fixedly connected to the output shaft of the motor 5. The driving wheel 4 meshes with the transmission wheel and can drive the entire turntable 8 to rotate, so that the teaching content display surface rotates with the device. Students in different positions can clearly see the content, effectively solving the problem of limited teaching perspective and enhancing the flexibility and comprehensiveness of teaching display.

[0022] like Figure 1-4 As shown, a guide rail 12 is installed at the bottom of the middle plate 6, and a drawer 13 is slidably connected to the guide rail 12, providing a large storage space for teaching materials, cards and other items. Teachers can quickly access the items they need, eliminating the clutter of teaching supplies and making teaching preparation more efficient and classroom flow smoother.

[0023] like Figure 1-4 As shown, a roller 14 is installed around the chassis 1 to reduce the friction between the device and the ground. A single person can easily push the device to move between classrooms and different teaching venues, breaking the limitations of fixed teaching venues, meeting the needs of diverse teaching scenario transformations, and improving the ease of use of teaching equipment.

[0024] like Figure 1-4 As shown, the middle plate 6 has a storage slot for holding teaching tools such as cards and ink pens, which is specially designed to store small teaching tools such as cards and ink pens, so that teachers can easily access teaching tools.

[0025] Operating principle of display board 7: When display board 7 is not unfolded, the entire device is in a retracted state. At this time, the middle plate 6 is placed horizontally and can be used as a table for convenient placement of teaching materials. When display board 7 needs to be unfolded for teaching, the operator first loosens the fixing bolts 11 on both sides of the middle plate 6. Loosening the fixing bolts 11 releases the fastening force between the middle plate 6 and the limiting member 10, allowing display board 7 to rotate around the hinge point. After rotating display board 7 90 degrees and adjusting it to a suitable display angle, tighten the fixing bolts 11 again. The fixing bolts 11, in cooperation with the limiting member 10, fix display board 7 at that angle, ensuring that display board 7 remains stable during teaching.

[0026] The interactive principle of the spinning wheel 8: When teaching English grammar tenses interactively, the teacher first takes out cards with magnets and writes different English words on different cards with an ink pen. The cards representing the base form of the word are attached to the small disc 802. Due to the magnetism of the small disc 802, the cards adhere firmly to its surface. The cards representing the tense variations (such as past tense to present continuous tense) are attached to the large disc 801, also using magnetism to fix the cards in place. Then, the teacher selects a student and has the student randomly spin the pointer 803 on the small disc 802. The pointer 803 spins freely on the small disc 802, and when it stops spinning, the word on the small disc 802 that the pointer 803 points to is the selected word. Next, the student needs to find the corresponding tense variation of that word on the large disc 801. In this way, students can visually compare the base form of the word and the tense variation, deepening their understanding and memorization of English grammar tenses.

[0027] The principle behind the switch between fixed turntable 8 and blackboard function: If the interactive function of turntable 8 is not used during teaching, the operator can pull out pin 9. Pulling out pin 9 releases the fixation restriction on turntable 8, allowing it to rotate 180 degrees. After rotating turntable 8 180 degrees, insert pin 9 into the corresponding positioning holes on turntable 8 and display board 7. The engagement of pin 9 and the positioning holes stabilizes turntable 8. At this point, the back of turntable 8 rotates to the front of display board 7, and the back of turntable 8 and the surface of display board 7 can be used as a writing area, just like a regular blackboard, allowing teachers to perform normal teaching operations such as writing on the board and writing teaching content.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
