Description

Technical Field

[0001] The utility model relates to the technical field of music auxiliary tools, in particular to a music teaching auxiliary bracket. Background Art

[0002] In music playing, an auxiliary support is needed to place music scores so that users can better read the music content on the score, facilitating performance teaching. For example, Chinese patent "CN218073982U" discloses "a portable accordion folding music score stand". When the support rotates the worm, it drives the worm wheel to rotate. When the worm wheel rotates, it drives the rotating shaft to rotate, and then drives the fixed connecting block and the placement support to rotate, so that the angle of the placement support changes, thereby adjusting the placement angle. Because the worm wheel and worm are self-locking, when the worm wheel and worm are rotated to the appropriate angle, the adjustment can be completed by simply stopping the placement support, making the device more flexible and the angle of the placement support adjustable according to people's needs. However, although the traditional support can adjust the angle by using the worm wheel and worm, the structure is relatively complex. When the placement support is subjected to external force, the worm wheel and worm will bear a large force and are prone to damage, thereby increasing the cost of use. In addition, the overall structure is relatively simple and cannot be adjusted to the height of use. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a music teaching auxiliary bracket, which solves the problems in the prior art that the bracket is easily damaged after being subjected to external force, and the overall structure is relatively simple and the height of use cannot be adjusted.

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a music teaching auxiliary bracket, comprising:

[0026] Base plate 1;

[0027] The support frame 4 is located at the top of the base plate 1 and is provided with an adjustment frame on both sides. The adjustment frame includes a first support rod 7 and a second support rod 8 that are rotatably connected to each other. One end of the first support rod 7 and one end of the second support rod 8 are respectively rotatably provided on the support frame 4 and the base plate 1, and the other end of the first support rod 7 and the other end of the second support rod 8 are respectively slidably provided on the base plate 1 and the support frame 4;

[0028] The supporting plate 2 is hinged to the top of the supporting frame 4 , and the supporting plate 2 is rotatably provided with an adjusting rod 5 , which is slidably provided on the supporting frame 4 for adjusting the angle of the supporting plate 2 .

[0029] In the embodiment of the present utility model, the support frame 4 and the base plate 1 are connected by an adjustment frame. When the height of the load-bearing plate 2 on the support frame 4 needs to be adjusted, since the adjustment frame is composed of a first support rod 7 and a second support rod 8 that are rotatably connected to each other, that is, the first support rod 7 and the second support rod 8 constitute a rotating cross structure, the first support rod 7 slidably connected to the base plate 1 can be directly pushed to make the end of the first support rod 7 slide on the base plate 1, thereby adjusting the distance between the end of the first support rod 7 and the end of the second support rod 8. When the distance between the end of the first support rod 7 and the end of the second support rod 8 becomes smaller, the angle between the first support rod 7 and the second support rod 8 becomes smaller, so that the other end of the first support rod 7 and the other end of the second support rod 8 lift the support frame 4, thereby achieving the raising of the load-bearing plate 2. Conversely, the angle between the first support rod 7 and the second support rod 8 becomes larger, and the support frame 4 is pulled to achieve a lowering of the height. The first support rod 7 and the second support rod 8 can be connected by an interference fit of a pin to provide a certain friction to achieve a certain self-locking effect.

[0030] Secondly, through the action of the adjusting rod 5, the end of the supporting plate 2 can be lifted, so that the supporting plate 2 rotates with the hinge end as the axis, thereby adjusting the angle of the supporting plate 2, and the music score on the supporting plate 2 can be displayed to the user at a more suitable angle. By sliding the adjusting rod 5 on the supporting frame 4 to adjust different angles of the supporting plate 2 and support the supporting plate 2, the supporting structure is simple, highly stable, and not easy to be damaged.

[0031] Specifically, such as Figure 2 As shown, the base plate 1 is correspondingly provided with two fixed blocks 101, and an adjusting screw 6 is rotatably provided between the two fixed blocks 101. The two first support rods 7 are connected by a connecting rod 9, and the connecting rod 9 is fixed with a driving block 901, and the driving block 901 is threadedly connected to the adjusting screw 6; in order to improve the stability of the load-bearing plate 2 after height adjustment, and to facilitate subsequent adjustment when it is used again, the two first support rods 7 are passed through the connecting rod 9 so that the connecting rod 9 can synchronously control the movement of the two first support rods 7 on the base plate 1, and by rotating the adjusting screw 6, the adjusting screw 6 drives the driving block 901 engaged therewith to move along the axis of the adjusting screw 6, thereby driving the connecting rod 9 to move on the base plate 1, realizing synchronous adjustment of the two first support rods 7. After adjustment, the stability is guaranteed under the self-locking of the thread, and the relative positions of the two will not change.

[0032] Furthermore, one of the fixing blocks 101 is provided with a knob 601 , and the adjusting screw 6 passes through the fixing block 101 and is fixedly connected to the knob 601 ; the knob 601 can facilitate the operator to adjust the adjusting screw 6 , making it more convenient to use.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, the support frame 4 is provided with a sliding groove 401 on both sides, and a plurality of clamping grooves 402 are arranged in the inner side of the sliding groove 401. The end of the adjusting rod 5 is fixedly provided with a fixed shaft 501, and the fixed shaft 501 is slidably arranged in the clamping groove 402 and clamped in one of the clamping grooves 402. In order to improve the stability of the bearing plate 2 after angle adjustment, when the fixed shaft 501 slides in the sliding groove 401, the angle between the adjusting rod 5 and the bearing plate 2 changes, thereby completing the support of the bearing plate 2. After angle adjustment, the fixed shaft 501 is directly lowered into the corresponding clamping groove 402 in the sliding groove 401, so that the fixed shaft 501 is limited and not easy to move in the sliding groove 401, thereby ensuring the stability of the bearing plate 2 after angle adjustment. Even when subjected to a larger force, the fixed shaft 501 can slide in the sliding groove 401 to do a part of buffering, avoiding damage to the overall structure.

[0034] Specifically, as shown in the figure, Figure 1 The hinged end of the bearing plate 2 is provided with two mounting seats 201, and the pressing plate 3 is arranged between the two mounting seats 201. The pressing plate 3 is rotatably arranged between the two mounting seats 201 through the rotating shaft 203. When the music sheet is placed on the bearing plate 2, the pressing plate 3 can be pressed on the surface of the music sheet, so that the music sheet on the bearing plate 2 will not fall off due to the inclined surface.

[0035] At the same time, as shown in the figure, Figure 3 The mounting seat 201 is provided with a torsion spring 202, and the torsion spring 202 is arranged on the pressing plate 3. The torsion spring 202 can exert a force on the pressing plate 3, so that the bearing plate 2 is always subjected to the pressure of the pressing plate 3, thereby ensuring the stability of the music sheet on the bearing plate 2. Moreover, after the music sheet is turned over, under the action of the pressing plate 3 and the torsion spring 202, the turned-over music sheet will not return to the original position.

[0036] Secondly, the pressing plate 3 is fixedly provided with a pull block 301; it is convenient to manually operate the pressing plate 3, so that the music sheet can be quickly placed between the bearing plate 2 and the pressing plate 3.

[0037] Specifically, as shown in the figure, Figure 1 The bottom of the bottom plate 1 is provided with a plurality of anti-skid pads 102; the friction between the bottom plate 1 and the working surface is increased, and the overall work is more stable. At the same time, in some other embodiments, a support structure can also be fixed at the bottom of the bottom plate 1, and the whole structure can be used in the air.

[0038] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
