DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, the present utility model provides a technical solution: a flip-type dictation device, which includes a base 1. On both sides of the top end of the base 1, there are columns 2 provided. The top ends of the two columns 2 are jointly connected with a U-shaped frame 3. Inside the U-shaped frame 3, there is a dictation component. The dictation component includes a flip frame 4 at one end inside the U-shaped frame 3. In the middle of one side of the flip frame 4, there is a rotating shaft 5 rotatably connected. On the other side of the flip frame 4, there is a fixed frame 6. On the front surface of the flip frame 4, there is a placement groove 7. Inside the placement groove 7, there is a student writing area 8. At the top and bottom of the student writing area 8, there are sliding plates 9 provided. On the inner top surface and inner bottom surface of the flip frame 4 and the fixed frame 6, there are sliding grooves 10 adapted to the sliding plates 9 provided. And on one side of the U-shaped frame 3, there is also a through hole 11 provided. Inside the through hole 11, there is a movable rod 12 provided. One end of the movable rod 12 is fixedly connected with a pulling disc 13. Between the pulling disc 13 and the U-shaped frame 3, there is a spring 14 provided. The spring 14 is simultaneously outside the surface of the movable rod 12. On the top surface and bottom surface of one side of the flip frame 4, there are fixing grooves 15 adapted to the end of the movable rod 12 provided. And on the rear side of the flip frame 4, there is a teacher writing area 19 provided. The flip frame 4 and the fixed frame 6 are horizontally aligned. When the student writing area 8 is stressed and moves, it is convenient for the student writing area 8 to slide from the inside of the flip frame 4 to the inside of the fixed frame 6 for placement. On the bottom surface of the base 1, there are anti-slip patterns provided, making the device more stable when placed;During use, the teacher writes teaching content within the teacher's writing area 19. Then, the pulling plate 13 is pulled to one side. At this time, the spring 14 is stressed and expands. At the same time, the pulling plate 13 drives the movable rod 12 to slide along the inner side of the through hole 11. When the movable rod 12 moves to a suitable position, the end of the movable rod 12 leaves the inner side of the corresponding fixed slot 15. Then, the teacher rotates the flipping frame 4 in place under the action of the rotating shaft 5. When the flipping frame 4 is rotated, the teacher's writing area 19 faces the rear side of the device. Then, the teacher releases the pulling plate 13. At this time, the spring 14 contracts without force, causing the end of the movable rod 12 to engage with the inner side of the corresponding fixed slot 15 to fix the flipping frame 4. Then, the teacher pushes the student writing area 8 towards the fixed frame 6. When the student writing area 8 moves, the student writing area 8 drives the sliding plate 9 to slide along the inner side of the sliding slot 10, so that the student writing area 8 finally lies inside the fixed frame 6. Then, the student steps forward and silently writes the teaching content on the surface of the student writing area 8. When the student finishes silent writing, the teacher pulls the pulling plate 13 again. At this time, the spring 14 is stressed and expands. At the same time, the pulling plate 13 drives the movable rod 12 to slide along the inner side of the through hole 11. When the movable rod 12 moves to a suitable position, the end of the movable rod 12 leaves the inner side of the corresponding fixed slot 15. Then, the teacher rotates the flipping frame 4 in place under the action of the rotating shaft 5. When the flipping frame 4 is rotated, the teacher's writing area 19 faces the front of the device again. Then, the teacher releases the pulling plate 13. At this time, the spring 14 contracts without force, causing the end of the movable rod 12 to engage with the inner side of the corresponding fixed slot 15 to fix the flipping frame 4. Then, the teacher compares the teaching content written on the surfaces of the teacher's writing area 19 and the student writing area 8 to check the correctness of the student's silent writing content, completing the operation. In the existing teaching environment, the silent writing device has a simple structure, being a simple writing board. The teacher cannot effectively check the students' silent writing. When the teacher writes content on the writing board, the students behind are likely to see the content written by the teacher when they do silent writing, and the teacher cannot effectively check the level and quality of the students' silent writing. By designing the base 1, the column 2, the looped frame 3, and the silent writing component, after the teacher writes the teaching content in the designated area, it can be turned so that the students cannot see the content to be silently written. Then, after the students silently write the teaching content, the teacher can turn the content he / she wrote over again to compare and check with the content silently written by the students, which can effectively check the quality of the students' silent writing after completion. The overall structure is compact and the operation is simple, worthy of popularization and use.
[0020] In this embodiment, preferably, please refer to Figure 1As shown, it further includes a placement component. The placement component includes a placement rod 16. The placement rod 16 is at the bottom end of the rectangular frame 3. A support rod 17 is also provided on the top surface of the base 1. The top end of the support rod 17 is fixedly connected to a placement box 18. The placement rod 16, the support rod 17, and the placement box 18 are all made of plastic, saving the input of manufacturing costs and being more economical and practical. By designing the placement component, the teacher can hang the dishcloth on the placement rod 16, and other teaching tools can be placed inside the placement box 18, effectively increasing the storage function of the dictation device and having strong practicability.
