[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides two technical solutions:

[0025] Figures 1-6 The first embodiment is shown: a height adjustment device for teaching aids, including a mounting frame 1, a mounting groove 11 on the rear side of the mounting frame 1, a bracket 2 symmetrically mounted on the top of the mounting frame 1, a side writing board 21 mounted on the front surface of the bracket 2, and a height adjustment component 3 inside the mounting groove 11; the height adjustment component 3 includes a motor 31, a lead screw 32 mounted on the output end of the motor 31, a lifting frame 33 threaded onto the outer wall of the lead screw 32, upright plates 34 mounted on the outer surfaces of both sides of the lifting frame 33, and four crossbars 35 mounted on the front surface of the upright plates 34, with each pair of crossbars 35 forming a group; a display screen 4 is provided on the front side of the upper group of crossbars 35, the front surface of the display screen 4 is on the same plane as the front surface of the side writing board 21, and the display screen 4 is positioned between the two side writing boards 21, and the left and right sides of the display screen 4 can move up and down along the sides of the side writing board 21.

[0026] Specifically, by placing the display screen 4 between the two side writing boards 21, and ensuring that the front surface of the display screen 4 is on the same plane as the front surface of the side writing boards 21, the step between the screen and the writing board in traditional teaching auxiliary display devices is eliminated. This optimizes the utilization efficiency of teaching space, avoids visual obstacles and abruptness, and allows teachers to switch between the writing board and the display screen 4 more naturally and smoothly during teaching, improving the continuity and comfort of teaching. In terms of height adjustment, the motor 31 in the height adjustment component 3 drives the lead screw 32 to rotate, which in turn drives the lifting frame 33, which is threadedly connected to the lead screw 32, to move up and down. This allows the horizontal bar 35 installed on the upright plate 34 and the display screen 4 on the front side of the horizontal bar 35 to be flexibly raised and lowered, accurately meeting the visual needs of students of different heights. This effectively solves the problem of some students having difficulty viewing traditional fixed-height screens, enhancing the adaptability and effectiveness of teaching.

[0027] In this embodiment, a fixing frame 37 is movably sleeved on the outer wall of the lead screw 32 near its top end, and the fixing frame 37 is fixed on the inner wall of the mounting groove 11. A guide rod 38 is symmetrically installed on the inner top surface of the fixing frame 37. The outer wall of the guide rod 38 slides through the top surface of the lifting frame 33 and extends downward. The bottom end of the guide rod 38 is fixedly connected to the inner bottom surface of the mounting groove 11.

[0028] Specifically, the fixed frame 37 provides a stable support point for the rotation of the lead screw 32, ensuring that the lead screw 32 remains vertical and stable during the lifting process of the lifting frame 33. On the other hand, the guide rod 38 symmetrically installed on the top surface of the fixed frame 37 allows the lifting frame 33 to slide up and down along the guide rod 38 under the drive of the lead screw 32, providing a precise guide path for the lifting of the lifting frame 33.

[0029] In this embodiment, the front side of the mounting bracket 1 is provided with an inspection port 12 that communicates with the mounting groove 11, and a front cover plate 13 is installed inside the inspection port 12 by bolts.

[0030] Specifically, by removing the bolts on the front cover plate 13, the inspection port 12 can be opened, allowing maintenance personnel to easily enter the mounting slot 11 to operate key components such as the motor 31, lead screw 32, and lifting frame 33. During normal use, the front cover plate 13 can keep the inside of the mounting slot 11 closed, preventing dust, debris, and other contaminants from entering.

[0031] Figures 1-6 The second embodiment is shown, and its main difference from the first embodiment is that a middle writing board 5 is provided on the front side of a set of crossbars 35 located below. The middle writing board 5 is the same width as the display screen 4. Multiple hanging plates 6 are installed on the rear surfaces of both the display screen 4 and the middle writing board 5, and the hanging plates 6 can be hung on the crossbars 35. A limiting groove 61 is formed on the outer surface of the hanging plate 6, and two limiting blocks 36 are fixedly connected to the rear surface of the crossbar 35. The limiting blocks 36 cooperate with the limiting groove 61.

[0032] Specifically, multiple hanging plates 6 are installed on the rear surfaces of both the display screen 4 and the middle writing board 5. These hanging plates 6 can be easily hung on the crossbar 35, realizing convenient connection between the display screen 4 and the middle writing board 5 and the crossbar 35. This not only facilitates installation and disassembly but also ensures their stability during use. The limiting groove 61 opened on the outer surface of the hanging plate 6 cooperates with the two limiting blocks 36 fixedly connected to the rear surface of the crossbar 35, further enhancing the fixing effect of the hanging plate 6 on the crossbar 35 and effectively preventing the display screen 4 and the middle writing board 5 from wobbling or shifting during use.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, when the height of the display screen 4 needs to be adjusted, the motor 31 is started, causing the lifting frame 33 to slide up and down along the guide rod 38 as it is driven to rise and fall by the lead screw 32. The four horizontal bars 35 on the upright plates 34 installed on the outer surfaces of both sides of the lifting frame 33 also rise and fall accordingly, thereby driving the display screen 4 to rise and fall to a suitable height. This solves the problem in existing teaching auxiliary display equipment where the screen height is fixed, making it difficult for some students to see the screen content clearly, which affects the teaching effect. At the same time, the front surface of the display screen 4 and the front surface of the side writing board 21 are on the same plane, thus eliminating the step between them and avoiding the visual abruptness caused by the height difference, thereby improving the students' learning experience.
