Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0019] Embodiment

[0020] Referring to the accompanying drawings of the specification, in an embodiment of the present utility model, an auxiliary teaching device for teaching includes an I-shaped frame 1 fixedly installed at the top of a support plate 9. Two fixed frames 3 are rotatably connected to both sides of the I-shaped frame 1. Square-shaped display openings 4 are formed on the front and rear sides of the fixed frame 3. T-shaped slide rails 5 are symmetrically arranged at the upper and lower ends of the inner wall of the fixed frame 3. A writing board 6 is movably arranged in the fixed frame 3. T-shaped sliders 7 are arranged on the upper and lower sides of the writing board 6. The T-shaped sliders 7 are correspondingly slidably arranged in the T-shaped slide rails 5. A lifting mechanism is installed at the bottom end of the support plate 9. The lifting mechanism includes two lifting rods 16 fixedly arranged between the support plate 9 and a base 15. A cross frame 17 is installed between the two lifting rods 16. A screw hole is formed in the middle of the cross frame 17, and a lead screw 18 is screwed into the screw hole. The top end of the lead screw 18 is rotatably connected to the support plate 9. Two grooves 10 are symmetrically formed on the support plate 9. A rotating shaft 2 located at the lower end of the fixed frame 3 extends through the support plate 9 and is rotatably connected to the groove 10 through a bearing. A toothed ring 12 is fixedly arranged on the outer wall of the rotating shaft 2 located in the groove 10. An auxiliary gear 11 is rotatably arranged on one side of the groove 10. Screw holes are formed on both sides of the support plate 9, and a limit screw 13 is screwed into the screw holes. Four writing boards 6 are provided. The length and height of the four writing boards 6 are greater than the length and width of the display opening 4. Handles 8 are fixedly installed on both sides of the writing board 6. Fixed buckles 19 are installed on one side of the front of the fixed frame 3. Fixed pieces 20 are movably installed on one side of the rear of the fixed frame 3, and a round hole is formed at the head end of the fixed piece 20. The round hole is adapted to be connected with the fixed buckle 19. The auxiliary gear 11 is meshed with the toothed ring 12. The head end of the limit screw 13 is adapted to the teeth of the toothed ring 12. The two fixed frames 3 can be turned inward or outward by 0-180 degrees in the I-shaped frame 1 through the rotating shaft. Two pull-out tool boxes 14 are arranged on the support plate 9.

[0021] Usage process:

[0022] In use, it is supported on the ground by the base 15, and the height of the fixed frame 3 is adjusted by the lifting mechanism so that the writing board 6 in the fixed frame 3 can be at a height convenient for writing, improving the writing comfort to adapt to different teaching needs and the heights of students. According to the content to be written, it can be written in modules and partitions on the front and back of multiple writing boards 6. Multiple writing boards can provide more writing content than a blackboard. A large amount of content can be written in advance. After finishing the explanation on one side of the writing board 6, the writing board 6 can be pulled out from the T-shaped slide rail 5 by holding the handle and turned over to write on the other side of the writing board 6 to continue teaching, or the content on another writing board can be presented in the display port 4, enabling the teacher to write classroom content on multiple writing boards 6 after class, saving time for the classroom, improving the teaching quality, enhancing the teaching experience, and making the teaching process more convenient and efficient; through the settings of the rotating shaft 2, groove 10, auxiliary gear 11, tooth ring 12, and limit screw 13, the fixed frame 3 can be rotated by moving the rotating shaft, and then limited and fixed by the limit screw 13 to prevent the fixed frame 3 from rotating. By adjusting the fixed frame 3 to be rotatable, the writing board 6 can be tilted at an appropriate angle left and right, facilitating students on both sides to view the content on the writing board, taking care of all students in all directions, and being flexible and convenient to use.

[0023] In the above process, through the settings of the fixed frame, display port, T-shaped slide rail, writing board, T-shaped slider, and handle, multiple writing boards are flexibly detachable, enabling the teacher to write the content to be taught in modules and partitions during lesson preparation. Thus, during teaching, only the writing board needs to be replaced or the content to be displayed can be shown at the display port by turning the writing board over, saving time for the classroom, improving the teaching quality, enhancing the teaching experience, and making the teaching process more convenient and efficient; through the movable connection of two fixed frames, the writing board can be tilted at an appropriate angle left and right, facilitating students on both sides to view the content on the writing board, taking care of all students in all directions, and being flexible and convenient to use; the structure of this application is simple, highly practical, and easy to operate, worthy of promotion.

[0024] The above are only the preferred embodiments of the present utility model. It should be noted that for those skilled in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
