Technical Field

[0001] This utility model belongs to the field of teaching aids technology, and more specifically, it relates to a multifunctional rotating English grammar demonstration device. Background Technology

[0002] Traditional classroom grammar teaching mainly relies on paper handouts, static wall charts, PPTs, or blackboards. Teachers often need to repeatedly erase or change teaching aids. Students can only view the material from the front, and the view of students in the back and side rows is obstructed, resulting in "not being able to see clearly, not being able to hear, and not being able to remember." At the same time, the switching efficiency is low. For example, different grammar topics (tenses, clauses, subjunctive mood, etc.) require multiple sets of wall charts or PPTs, and teachers frequently change teaching aids, which disrupts the teaching rhythm.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a multifunctional rotating English grammar demonstration device in order to achieve a more practical purpose. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a multifunctional rotating English grammar demonstration device, including a base 1. Four wheels 2 are installed at the four corners of the base 1 for movement. An electric telescopic rod 5 is installed above the base 1. An outer disc 6 is installed at the top of the electric telescopic rod 5. An inner disc 7 is rotatably installed on the inner wall of the outer disc 6. A teaching turntable 13 and a demonstration board 14 are respectively arranged on both sides of the upper surface of the inner disc 7. Multiple flip-board assemblies for demonstrating changes in English grammar sentence structures are arranged on one side of the teaching turntable 13. Each flip-board assembly includes a connecting block 18, which is located on one side of the teaching turntable 13. Connecting rods 20 are installed in the four directions (up, down, left, and right) of the connecting block 18. A first flip-board 21 and a second flip-board are rotatably installed on the outer wall of each connecting rod 20. 22, third flip board 23, fourth flip board 24, and a U-shaped frame 19 for hand gripping is installed on one side of the connecting block 18. The first flip board 21, second flip board 22, third flip board 23, and fourth flip board 24 are arranged sequentially from the inside out, and different grammatical structures are set on the front and back of each first flip board 21, second flip board 22, third flip board 23, and fourth flip board 24. By setting corresponding grammatical structures and sentence structure transformations on the front and back of the first flip board 21, second flip board 22, third flip board 23, and fourth flip board 24, students can actively flip and compare them. This setting allows for different sentence patterns and grammatical themes to be set on the front and back of each flip board for learning, eliminating the need for teachers to frequently change teaching aids.

[0027] One side of the demonstration board 14 is provided with a writable area 15 for teachers to demonstrate and write. With the demonstration board 14, teachers can demonstrate teaching on the writable area 15 on one side. Combined with the use of the inner plate 7 and the outer plate 6, the device can be rotated, making it convenient for students and teachers to use.

[0028] The inner wall of the outer disc 6 is provided with a limiting groove 8. The inner disc 7 is rotatably installed on the inner wall of the limiting groove 8 through the outer wall. Under the action of the limiting groove 8, the inner disc 7 is stably rotated inside the outer disc 6, which facilitates the rotation of the device and makes it convenient for students and teachers to use.

[0029] The outer disc 6 has connecting shafts 10 installed on both sides of its upper surface. Each connecting shaft 10 has a connecting seat 11 installed at its top. Each connecting seat 11 has a connecting arm 12 rotatably connected to its top. The opposite ends of the two connecting arms 12 are respectively fixed to one side of the teaching turntable 13 and the demonstration board 14. Through the rotatable connection of the connecting arms 12 and the connecting seats 11, the teaching turntable 13 and the demonstration board 14 can rotate independently, making it more convenient for students to use and view.

[0030] The inner wall of the teaching turntable 13 is equipped with a first magnet 16, and a second magnet 17 is installed on one side of the connecting block 18. The second magnet 17 is attracted to the first magnet 16. Through the combined use of the first magnet 16 and the second magnet 17, the flip panel assembly can be quickly disassembled and installed to change new grammar and sentence structures.

[0031] The inner disc 7 has a lever 9 installed at the center of its upper surface, which facilitates the rotation of the inner disc 7.

[0032] The base 1 has a mounting frame 4 installed on its upper surface. A handrail 3 for pushing the vehicle is installed on one side of the mounting frame 4. The mounting frame 4 is fitted onto the outer wall of the electric telescopic pole 5. The vehicle can be pushed by the handrail 3 and the operation of the electric telescopic pole 5 can be stabilized by the mounting frame 4.

[0033] Two smooth rods 25 are installed at the bottom of the outer disc body 6. Rod sleeves 26 are slidably installed on the outer side walls of the two smooth rods 25. The bottom of the two rod sleeves 26 are fixed to the mounting frame 4. Through the action of the rod sleeves 26 and the smooth rods 25, the outer disc body 6 is more stable when it is raised.

[0034] The working principle of this embodiment is as follows: The movable wheels 2 are installed at the four corners below the base 1, facilitating the overall movement of the device. When the device needs to be moved to a suitable position, the armrest frame 3 is pushed, and the movable wheels 2 allow for easy movement. The electric telescopic rod 5 is installed above the base 1, with an outer disc 6 mounted on its top. When the device height needs to be adjusted, the electric telescopic rod 5 is activated, and its extension and retraction change the distance between the outer disc 6 and the base 1, thereby adjusting the device height. The inner wall of the outer disc 6 has a rotatably mounted inner disc 7. The limiting groove 8 on the inner wall of the outer disc 6 restricts the rotational position of the inner disc 7. The inner disc 7 can be rotated using the lever 9. When the inner disc 7 is rotated, its outer wall is within the limiting groove 8. Stable rotation allows for easy repositioning of components such as the teaching turntable 13 and demonstration board 14 on the inner disc 7, facilitating use by students and teachers. Multiple flip-board assemblies are located on one side of the teaching turntable 13. Each flip-board assembly includes a connecting block 18. The outer walls of the connecting rods 20 in the four directions (up, down, left, right) of the connecting block 18 are respectively rotatably fitted with the first flip-board 21, the second flip-board 22, the third flip-board 23, and the fourth flip-board 24. Each flip-board has different grammatical structures on its front and back. When students need to compare sentence structure changes, they can flip each flip-board to view the grammatical content on both sides, using the different sentence patterns and grammatical themes on the front and back of the flip-board for learning.

[0035] Secondly, connecting seats 11 are installed at the top of the connecting shafts 10 on both sides of the upper surface of the outer disc 6. Connecting arms 12 are rotatably connected to the top of the connecting seats 11. The opposite ends of the connecting arms 12 are fixed to one side of the teaching turntable 13 and the demonstration board 14, respectively. By rotating the connection between the connecting arms 12 and the connecting seats 11, the angles of the teaching turntable 13 and the demonstration board 14 can be changed independently. This makes it easier for students to view the teaching content. At the same time, when the teacher demonstrates writing in the writable area 15 of the demonstration board 14, the angle can also be adjusted to a suitable position. The inner wall of the teaching turntable 13 has a first magnet 16, and one side of the connecting block 18 has a second magnet. 17. When it is necessary to change to new grammar and sentence structure, the flip panel assembly can be removed from the teaching turntable 13 by overcoming the magnetic attraction. When installing the new flip panel assembly, the first magnetic attraction 16 and the second magnetic attraction 17 are used to quickly complete the installation. A light rod 25 is installed at the bottom of the outer plate 6. A rod sleeve 26 is slidably installed on the outer wall of the light rod 25. The bottom of the rod sleeve 26 is fixed to the mounting frame 4. When the electric telescopic rod 5 drives the outer plate 6 to rise, the rod sleeve 26 slides on the light rod 25, thereby providing stable support for the outer plate 6, preventing the outer plate 6 from shaking during the raising process, and ensuring the overall stability of the device.
