[0021] 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.

[0022] Example 1

[0023] This embodiment provides a scale teaching device for music education, such as... Figure 1-5 As shown, the scale teaching device includes a base plate 1, an adjustment structure 2 is installed on the end face of the base plate 1, a scale placement plate 3 is installed on the adjustment structure 2, and two sets of fixing structures 4 are symmetrically installed on the front and the upper and lower sides of the scale placement plate 3.

[0024] The fixed structure 4 includes an L-shaped plate 41 installed on the front of the scale placement plate 3. Horizontal bars 42 are slidably installed on the L-shaped plate 41 and on both sides through through holes 411. The ends of the two sets of horizontal bars 42 near the scale placement plate 3 are connected by a pressure plate 43. A second spring 44 is installed on the end face of the pressure plate 43 and outside the horizontal bars 42. A pull plate 45 is installed on the side wall of the pressure plate 43.

[0025] In use, the user drives the pull plate 45 to move closer to the fixed plate 46. The pull plate 45 drives the pressure plate 43 to move, and the pressure plate 43 drives the two sets of crossbars 42 to move synchronously away from the scale placement plate 3. The pressure plate 43 separates from the front of the scale placement plate 3 by compressing the two sets of second springs 44. The scale drawing can be placed between the scale placement plate 3 and the pressure plate 43. When the pull plate 45 is released, the pressure plate 43 is pushed back towards the scale placement plate 3 by the reset action of the second springs 44 until it contacts the end face of the scale placement plate 3, thus achieving the function of quickly fixing the scale drawing. If the scale drawing is large, it can be used with the lower fixing structure 4 to fix the scale. The drawing is fixed in place; in the step of fixing the scale drawing, when the pressure plate 43 drives the two sets of crossbars 42 to move synchronously away from the scale placement plate 3, and then the back of the pressure plate 43 separates from the front of the scale placement plate 3, if the scale drawing has been installed before, the scale drawing will fall naturally without control in this step, and the scale drawing can be quickly taken out. This realizes the function of quickly fixing or quickly taking out the scale drawing, avoiding the problem that the existing scale teaching devices for music education lack the function of quickly fixing and taking out the scale drawing, which makes fixing and taking out the scale drawing more troublesome. It reduces the time investment in fixing and taking out the scale drawing, thus providing convenience for music teaching.

[0026] In this embodiment, the inner cavity end face of the L-shaped plate 41 is connected to the end of the second spring 44 away from the pressure plate 43; an opening 412 is provided on the L-shaped plate 41 and corresponding to the pull plate 45; a fixing plate 46 is installed on the L-shaped plate 41 and located in front of the opening 412.

[0027] With the fixed plate 46, when the pull plate 45 is pulled in the opposite direction to the fixed plate 46, the fingers are placed on both sides of the pull plate 45 and the fixed plate 46, with the fixed plate 46 as the reference plate, which makes it convenient to pull the pull plate 45.

[0028] In this embodiment, a mounting bracket 5 is installed on the end face of the scale placement plate 3, and a lighting lamp 6 is installed on the other end of the mounting bracket 5;

[0029] Among them, by setting up the lighting lamp 6, in a dimly lit environment, the lighting lamp 6 can be turned on to illuminate the scale diagram on the scale placement board 3, making it easier for students to view and learn;

[0030] In this embodiment, a walking wheel 10 is installed at the bottom of the base plate 1 and at the corner;

[0031] The presence of wheels 10 facilitates the movement of the scale teaching device. Since the wheels 10 are lockable casters, they also make it easy to park and lock the device while moving it.

[0032] Example 2

[0033] Unlike Embodiment 1, the existing music education scale teaching device cannot adjust the height according to the height of different users. Therefore, the adjustment structure 2 includes a supporting outer cylinder 21 installed on the end face of the base plate 1. The inner cavity of the supporting outer cylinder 21 is slidably installed with a telescopic inner rod 22 connected to the bottom of the scale placement plate 3. A fixed cylinder 23 is installed on the front of the supporting outer cylinder 21. A plug rod 24 is slidably installed on the fixed cylinder 23 through a connecting hole. An installation ring 25 is installed on the outer wall of the plug rod 24 and is slidably connected to the inner wall of the fixed cylinder 23. A first spring 26 is installed on the installation ring 25 and located outside the plug rod 24.

[0034] In use, different users can pull the insertion rod 24 away from the limiting hole 221, so that the rear end of the insertion rod 24 is away from the limiting hole 221. Then, according to the height of different users, the telescopic inner rod 22 is driven to slide up and down in the supporting outer cylinder 21. After the height is determined, the user finds the closest limiting hole 221 and aligns it with the insertion rod 24. The insertion rod 24 is released, and under the reset action of the first spring 26, the mounting ring 25 is pushed to move towards the side wall of the supporting outer cylinder 21. The mounting ring 25 drives the rear end of the insertion rod 24 to insert into the corresponding limiting hole 221, realizing the height adjustment function of the scale teaching device. This avoids the problem that existing music education scale teaching devices cannot adjust the height according to the height of different users, providing convenience for users of different heights and improving the use effect of the scale teaching device.

[0035] In this embodiment, the side wall of the supporting outer cylinder 21 is provided with multiple sets of limiting holes 221, which are evenly distributed on the side wall of the supporting outer cylinder 21. The inner cavity of the fixing cylinder 23 is connected to the end of the first spring 26 away from the mounting ring 25. The rear end of the insertion rod 24 passes through the side wall of the supporting outer cylinder 21 and extends into the limiting hole 221. The end face of the bottom plate 1 is symmetrically mounted with a mounting cylinder 7. The inner wall of the mounting cylinder 7 is slidably mounted with a vertical rod 8 connected to the bottom of the scale placement plate 3. The outer wall of the mounting cylinder 7 is symmetrically mounted with a reinforcing rod 9 connected to the end face of the bottom plate 1.

[0036] The auxiliary adjustment structure 2 adjusts the height of the scale teaching device by using the mounting cylinder 7 and the vertical rod 8 together, which also increases the installation stability of the scale placement plate 3.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the scope of protection of this utility model.
