Description

Technical Field

[0001] The invention relates to the field of music teaching equipment, and in particular to a stably rotatable mobile bracket for music teaching. Background Art

[0002] During music teaching, music teachers are often required to teach students how to play musical instruments on site. However, due to venue limitations, students usually learn around the teacher. In order to teach students more comprehensively, teachers often need to use a rotatable mobile stand at the bottom to facilitate a more comprehensive display. However, the existing rotatable mobile stand is often driven to rotate on one side by a motor, which causes the mobile stand to rotate unsteadily, easily interrupting the rhythm of music teaching and affecting the viewing experience.

[0003] For example, a revolving stage proposed in CN109898897B includes a stage base, supporting columns, a stage deck, an elevator, a rotating device and a platform. The stage base is fixedly connected to a plurality of supporting columns, which are fixedly connected to the stage deck. The stage deck is provided with a through hole for accommodating the platform to move vertically and rotate horizontally. A lift is provided directly below the through hole. The chassis of the elevator is bolted to the stage base. A rotating device is provided above the working surface of the elevator. The rotating device includes a motor, a turntable, a wheel and a supporting shaft. The wheel includes a lower base plate, a cylindrical block and an upper base plate. The upper base plate is fixedly connected to the platform. The invention has a simple structure and occupies a small area. Compared with the traditional gear meshing tooth drive method, the rack and the wheel not only have less wear, but also are cheaper to make. The rotating device runs more smoothly and safely, and is suitable for various stage performance venues. However, the above-mentioned problems are not solved.

[0004] The present invention can rotate the movable bracket more stably and steadily through the rotating device, thereby ensuring the rhythm and stability during music teaching. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0031] Hereinafter, a stably rotatable mobile bracket for music teaching according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 - Fig. 9 As shown, the stably rotatable mobile bracket for music teaching includes a bottom plate 13, a balancing device is provided above the bottom plate 13, a rotating device is provided above the balancing device, a sound insulation device is provided inside the rotating device, and a moving device is provided below the bottom plate 13.

[0032] like Figure 6 , Figure 7 and Figure 8As shown, the stably rotatable mobile bracket for music teaching includes a rotating device, which includes a mounting plate 1, a slide rail 3, a motor 4, a worm 5, a bevel gear 6, a gear set 7, a fixing ring 9 and a table 12.

On the side of the central gear, the fixed ring 9 is rotatably mounted on the mounting plate 1, the table 12 is fixed above the height ring, a gear ring 10 is provided below the fixed ring 9, the gear ring 10 is meshed with the gear set 7, a slide groove is provided between the slide rail 3 and the fixed ring 9, a rotatable roller is provided in the slide groove, and the fixed ring 9 is supported by the roller, a protruding baffle is also provided in the slide groove, a mounting groove is provided on the baffle, and the mounting groove fits with the roller, and a rotatable and evenly distributed ball is also provided on the side of the slide rail 3, and the ball contacts the inner side of the fixed ring 9.

[0033] In a specific embodiment: when in use, the motor 4 is started to rotate by an external power supply, thereby driving the worm 5 to rotate, and the bevel gear 6 drives the gear set 7, so that the gear ring 10 drives the fixed ring 9 and the table 12 on the fixed ring 9 to rotate. During rotation, since the gear set 7 is a reduction gear set 7 and is evenly meshed with the gear ring 10, the rotation of the table 12 is more stable, and through the combination of the worm 5 and the bevel gear 6, the table 12 will not rotate under the action of external force, thereby achieving a self-locking effect.

[0034] like Figure 7 and Fig. 9 As shown, the stably rotatable mobile bracket for music teaching includes a sound insulation device, which includes a first sound absorbing plate 8 and a second sound absorbing plate 11. The first sound absorbing plate 8 is arranged on the mounting plate 1 and is located on the outside of the gear set 7. The second sound absorbing plate 11 is arranged on the fixing ring 9. The upper part of the first sound absorbing plate 8 and the lower part of the second sound absorbing plate 11 are provided with arc-shaped protrusions and grooves that are staggered with each other.

[0035] In a specific embodiment: when in use, the first sound absorbing panel 8 at the bottom and the second sound absorbing panel 11 at the top wrap the worm 5, the bevel gear 6 and the gear set 7, thereby isolating and absorbing the noise generated between the gears, thereby reducing the impact on music teaching.

[0036] like Figure 3 , Figure 4 and Figure 6As shown, the stably rotatable mobile bracket for music teaching includes a balancing device, which includes a support spring 2, a first ball head 14, a threaded sleeve 15 and a second ball head 16.

[0037] In a specific embodiment: when in use, the mounting plate 1 is supported by the support spring 2, and the distance between the first ball head 14 and the second ball head 16 is adjusted by rotating the threaded sleeve 15, thereby adjusting the angle of the mounting plate 1, so that the table 12 above the mounting plate 1 remains horizontal, so that the rotating device can rotate more smoothly.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, the stably rotatable mobile bracket for music teaching includes a moving device, which includes a step, a limit ring 19 and a universal wheel 20. The step is slidably installed at both ends of the base plate 13, a damping rod 18 is provided between the step and the base plate 13, a handle is provided on the step, the universal wheel 20 is installed below the base plate 13, the limit ring 19 is fixed below the step, the limit ring 19 is sleeved on the universal wheel 20, a slide groove is provided in the middle of the limit ring 19, and through holes are provided above and below the limit ring 19, and the diameter of the through hole above the limit ring 19 is larger than the diameter of the through hole below.

[0039] In a specific embodiment: when in use, the mobile bracket is moved by the universal wheel 20. During music teaching, the limit ring 19 is driven downward by pressing down the step, so that the limit ring 19 presses the brake structure of the universal wheel 20, so that the mobile bracket remains stable. During the process, the damping rod 18 will slow down the descending speed of the step, so that the user has no sense of segmentation when stepping on the step, and the limit ring 19 can press the brake structure of the universal wheel 20.

[0040] After use, the step is lifted by the handle to unlock the brake structure of the universal wheel 20 at the lower end of the limiting ring 19 .

[0041] Working principle: When in use, the mobile bracket is moved by the universal wheel 20. During music teaching, the limit ring 19 is driven downward by pressing the step 17, so that the limit ring 19 presses the brake structure of the universal wheel 20, so that the mobile bracket remains stable, and then the mounting plate 1 is supported by the support spring 2, and the distance between the first ball head 14 and the second ball head 16 is adjusted by rotating the threaded sleeve 15, so as to adjust the angle of the mounting plate 1, so that the table 12 above the mounting plate 1 remains horizontal, and the motor 4 is started to rotate by an external power supply, thereby driving the worm 5 to rotate, and the bevel gear 6 drives the gear set 7, so that the gear ring 10 drives the fixed ring 9 and the table 12 on the fixed ring 9 to rotate.
