The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a preschool education teaching demonstration tool, including two fixed supports 1, a connecting rod 2 fixedly connected between the two fixed supports 1, lifting grooves 6 opened at opposite ends of the two fixed supports 1, toothed plates 8 slidably connected to the inner walls of the two lifting grooves 6, display whiteboards 7 fixedly connected to opposite ends of the two toothed plates 8, a sliding groove 4 opened on one side of the display whiteboard 7, a movable hook 5 slidably connected to the inner wall of the sliding groove 4, a storage box 3 fixedly installed on one side of the corresponding fixed support 1, and grooves 13 opened at opposite ends of the inner walls of the two lifting grooves 6, with adjustment components arranged inside the two grooves 13.
[0024] Furthermore, the adjustment assembly includes two gears 12, with the two sides of each gear 12 rotatably connected to the inner wall of the corresponding groove 13. Parts of the outer surfaces of the two gears 12 extend into the interior of the corresponding lifting groove 6 and mesh with the tooth surfaces of the corresponding tooth plates 8.
[0025] Furthermore, a rotating groove 18 is provided on one side of the corresponding fixed bracket 1. The interior of the rotating groove 18 is connected to the interior of the groove 13. A rotating rod 9 is rotatably connected inside the rotating groove 18. One end of the rotating rod 9 is fixedly connected to one side of the corresponding gear 12.
[0026] Furthermore, a through groove 10 is provided on one side of the corresponding fixed bracket 1. The interior of the through groove 10 is connected to the interior of the corresponding groove 13. A locking block 14 is slidably connected to the inner wall of the through groove 10. One end of the locking block 14 is tooth-shaped, and the tooth end of the locking block 14 contacts the tooth end of the corresponding gear 12.
[0027] Furthermore, a limiting groove 15 is formed on the bottom surface of the inner wall of the through groove 10. A limiting block 16 is slidably connected to the inner wall of the limiting groove 15. The top end of the limiting block 16 is fixedly connected to the bottom end of the locking block 14. A pressure spring 17 is fixedly connected to one side of the limiting block 16. The end of the pressure spring 17 away from the limiting block 16 is fixedly connected to one side of the inner wall of the limiting groove 15.
[0028] Furthermore, a slider 11 is slidably connected to the inner wall of the through groove 10, and one end of the slider 11 is fixedly connected to one side of the locking block 14.
[0029] Furthermore, when the teacher needs to adjust the height of the whiteboard 7, the slider 11 can be activated. The slider 11 then moves the locking block 14, causing the locking block 14 to press the pressure spring 17 against the limiting block 16. The teeth of the locking block 14 then cease contact with the outer surface of the gear 12, allowing the gear 12 to disengage and regain its rotational capacity. Simultaneously, the rotating rod 9 is rotated, causing the gear 12 to rotate. The gear 12 then moves the corresponding gear plate 8 up and down. Simultaneously, the gear plate 8 on the other side rotates the gear 12 on the other side, thus adjusting the height of the whiteboard 7. Once the height adjustment of the whiteboard 7 is complete, the slider 11 can be released. Under the action of the pressure spring 17, the locking block 14 automatically resets, allowing the teeth of the locking block 14 to continue pressing against the outer surface of the corresponding gear 12, thus locking the gear 12. This ensures that the adjusted whiteboard 7 is stably fixed between the two fixed supports 1.
[0030] Furthermore, the rotating rod 9 drives the gear 12 to rotate, and then the gear 12 drives the corresponding toothed plate 8 to move up and down. The corresponding toothed plate then drives the display whiteboard to adjust its height. Thus, the height of the display whiteboard can be flexibly adjusted by rotating the rotating rod 9. The operation process is simple and quick, which makes it convenient for teachers to adjust the height of the display whiteboard and further improves the practicality of the display teaching aid.
[0031] Furthermore, by setting up multiple movable hooks 5, teachers can hang pictures and other objects that need to be displayed on one side of the whiteboard 7, thereby increasing the flexibility of teaching interaction and effectively improving teaching results.
[0032] Furthermore, the storage box 3 allows teachers to conveniently store frequently used small items in the classroom, making them readily available for use later.
[0033] Working principle: When the teacher needs to adjust the height of the whiteboard 7, the slider 11 is activated. The slider 11 then moves the locking block 14, which in turn causes the locking block 14 to press the pressure spring 17 against the limiting block 16. The teeth of the locking block 14 then stop contacting the outer surface of the gear 12, allowing the gear 12 to disengage and regain its rotational capacity. Simultaneously, the rotating rod 9 is rotated, causing the gear 12 to rotate. The gear 12 then moves the corresponding gear plate 8 up and down. At the same time, the gear plate 8 on the other side rotates the gear 12 on the other side, thus adjusting the height of the whiteboard 7. Once the height adjustment of the whiteboard 7 is complete, the slider 11 is released. Under the action of the pressure spring 17, the locking block 14 automatically resets, causing the teeth of the locking block 14 to continue pressing against the outer surface of the corresponding gear 12, thus locking the gear 12. This ensures that the adjusted whiteboard 7 is stably fixed between the two fixed supports 1.
[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
