Description

Technical Field

[0001] This utility model relates to the field of music stand device technology, and in particular to a music stand. Background Technology

[0002] In music performance and learning, holding sheet music can easily cause arm pain, unstable sheet music, and disruption of rhythm. Therefore, sheet music holders have emerged as an important auxiliary device in the music field. They are mainly used in professional music performances, such as symphony orchestras and solo concerts, to help performers stabilize the sheet music; amateur music lovers also frequently use them for home practice or small gatherings.

[0003] The sheet music holder consists of a main support, a sheet music support plate, and adjustment components: the main support is mostly made of metal or high-strength plastic, with a tripod or folding design at the bottom, balancing stability and portability; the support plate is mostly rectangular, with anti-slip strips or clips to prevent the sheet music from slipping, and some are adjustable in angle; the adjustment components include a height adjustment rod and an angle adjustment knob to accommodate different heights and reading habits;

[0004] Existing technologies for music score holders have significant shortcomings. Height adjustment is often fixed or has a complex structure, lacking convenient locking and reset mechanisms, making it difficult to quickly adapt to users of different heights and easily leading to height discomfort. Fixed angles lack reliable structures, making it difficult to stably fix the music score angle, which can easily cause the score to tilt and slip, and it cannot flexibly adapt to different reading angles. Furthermore, the music score often needs to be held in hand, causing arm pain and preventing simultaneous flexible adjustment of height and angle, which is insufficient to meet the needs of performance and learning. Therefore, a music score holder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a music score holder, which aims to improve the problem of difficulty in angle adjustment.

[0030] 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.

[0031] Reference Figures 1-6 An embodiment of this utility model provides a music score holder, comprising a support 1, a housing 2 fixedly connected to the middle of the support 1, a lifting column 3 slidably connected to the inner side of the housing 2, a support base 4 fixedly connected to the top of the lifting column 3, fixing blocks 5 fixedly connected to both sides of the support base 4, a rotating pin 6 fixedly connected to the inner side of the fixing block 5, a support frame 7 rotatably connected to one side of the rotating pin 6, a connecting frame 11 fixedly connected to both sides of the support frame 7, a fixing pin 10 rotatably connected to the inner side of the connecting frame 11, a support rod 9 rotatably connected to the outer side of the fixing pin 10, a locking spring 19 provided on the inner side of the support rod 9, a slider 20 slidably connected inside the support rod 9, a compression ball 18 fixedly connected to one side of the slider 20, and a pull pin assembly 12 fixedly connected to the outer side of the housing 2.

[0032] The bracket 1 serves as the overall support base, providing a stable mounting carrier for the housing 2. The housing 2, through its sliding engagement with the lifting column 3, enables the lifting column 3 to move up and down, thereby driving the top support base 4 to adjust its height. The fixing block 5 on the support base 4 provides a fulcrum for the support frame 7 through the rotating pin 6, allowing the support frame 7 to adjust its tilt angle around the rotating pin 6 to meet different reading angle requirements. The connecting frame 11 is connected to the support rod 9 through the fixing pin 10. The support rod 9 can rotate around the fixing pin 10. When the angle of the support frame 7 is adjusted, the support rod 9 rotates accordingly. The locking spring 19 inside pushes the slider 20 through elastic force, causing the slider 20 to push the extrusion ball 18 outward. Finally, the angle is fixed through the engagement of the extrusion ball 18 with the corresponding locking hole 8. The pull pin assembly 12 is used to lock the height position of the lifting column 3 to prevent it from sliding on its own during use.

[0033] Reference Figures 1-4 The pull pin assembly 12 includes a locking sleeve 13, a locking block 15 is slidably connected inside the locking sleeve 13, a locking pin 16 is fixedly connected in the middle of the locking block 15, and a spring 14 is sleeved on the outside of the locking pin 16.

[0034] The locking sleeve 13 serves as the overall mounting housing for the pull pin assembly 12, providing space for the locking block 15, locking pin 16, and spring 14 to be accommodated and guided. The sliding fit between the locking block 15 and the locking sleeve 13 ensures that the locking pin 16 can move stably along the axial direction of the locking sleeve 13. The spring 14 is sleeved on the outside of the locking pin 16 and stores or releases elastic force through its own elastic deformation to provide power for the reset of the locking pin 16. When an external force pulls the locking pin 16, the spring 14 is compressed. After the external force disappears, the elastic force of the spring 14 pushes the locking block 15 to drive the locking pin 16 back to its initial position.

[0035] Reference Figure 4 One side of the spring 14 is fixedly connected to the outside of the lock block 15, and the other side of the spring 14 is fixedly connected to the inner wall of the lock sleeve 13.

[0036] The two ends of the spring 14 are fixed to the inner walls of the locking block 15 and the locking sleeve 13, respectively, forming a fixed elastic force structure. When the locking pin 16 drives the locking block 15 to move away from the lifting column 3, the spring 14 is stretched or compressed, generating an elastic force opposite to the direction of movement. This elastic force ensures that the locking block 15 always has a tendency to move towards the lifting column 3, so that the locking pin 16 can be tightly engaged in the corresponding locking structure of the lifting column 3, thereby achieving the height locking of the lifting column 3.

[0037] Reference Figures 3-4 A handle 17 is fixedly connected to one side of the locking pin 16, and the locking pin 16 is slidably connected to the inside of the lock sleeve 13.

[0038] The handle 17 provides a point of force for the user to pull or push the handle 17 manually, so as to drive the locking pin 16 to slide inside the lock sleeve 13. The sliding cooperation between the locking pin 16 and the lock sleeve 13 ensures that the locking pin 16 will not deviate during the movement, and ensures that it can be accurately inserted into or disengaged from the locking position of the lifting column 3, thereby realizing the adjustment and fixed switching of the height of the lifting column 3.

[0039] Reference Figures 1-2 The support base 4 has locking holes 8 on both the left and right sides, and the compression ball 18 is engaged with the inner wall of the locking hole 8.

[0040] The locking hole 8 on the support base 4 provides a locking point for the compression ball 18. When the angle of the support frame 7 is adjusted, the support rod 9 drives the compression ball 18 to move. When the compression ball 18 moves to the position of the locking hole 8, under the elastic force of the locking spring 19, the compression ball 18 is locked into the inner wall of the locking hole 8. Through the friction and locking force between the compression ball 18 and the locking hole 8, the further rotation of the support rod 9 is restricted, thereby fixing the support frame 7 at the current angle and preventing the support frame 7 from rotating on its own during use, which would cause the sheet music to tilt or slip.

[0041] Reference Figures 3-4 The locking sleeve 13 is fixedly connected to the outside of the housing 2.

[0042] By fixing the locking sleeve 13 to the outside of the housing 2, the pull pin assembly 12 and the housing 2 form a stable overall structure, ensuring that the locking pin 16 can be accurately aligned with the lifting column 3 inside the housing 2. This avoids the locking pin 16 failing to accurately lock the lifting column 3 due to the loosening of the locking sleeve 13, while providing a stable support base for the user to operate the handle 17, ensuring the smoothness of the height adjustment operation.

[0043] Reference Figures 3-4 The locking pin 16 penetrates the housing 2 and is fixedly connected to the lifting column 3.

[0044] After the locking pin 16 passes through the housing 2, it is fixed to the lifting column 3. When it is necessary to adjust the height of the lifting column 3, pull the handle 17 to drive the locking pin 16 to disengage from the locking structure on the housing 2. At this time, the lifting column 3 can slide freely inside the housing 2. After adjusting to the appropriate height, release the handle 17. Under the elastic force of the spring 14, the locking pin 16 passes through the housing 2 again and is fixed to the lifting column 3. The movement of the lifting column 3 is restricted by the cooperation between the locking pin 16 and the housing 2, so as to fix the height of the lifting column 3 and ensure the height stability of the music score rack during use.

[0045] Working principle: When this music score holder is in operation, the support frame 1 serves as the overall support base. The centrally fixed housing 2 provides sliding space for the lifting column 3. When the height needs to be adjusted, pulling the handle 17 moves the locking block 15 and the locking pin 16 fixed in the middle of the locking block 15. At this time, the spring 14, which is sleeved on the outside of the locking pin 16 and whose two ends are respectively fixed to the outside of the locking block 15 and the inner wall of the locking sleeve 13, is compressed. The locking pin 16 is released from its fixed state through the housing 2 and the lifting column 3, and the lifting column 3 can slide freely inside the housing 2. After adjusting to the appropriate height, the handle 17 is released, and the spring 14 pushes the locking block 15 to drive the locking pin 16 to re-penetrate the housing 2 and fix it to the lifting column 3, thus achieving height locking. The support frame fixed at the top of the lifting column 3... Fixed blocks 5 are fixed on the left and right sides of the support 4. The rotating pin 6 inside the fixed block 5 provides a fulcrum for the support frame 7. When the tilt angle of the support frame 7 is adjusted, the connecting frame 11 drives the support rod 9 to rotate through the fixed pin 10 connected to the inside. The locking spring 19 inside the support rod 9 pushes the slider 20 that is slidably connected inside, causing the extrusion ball 18 on one side of the slider 20 to push outward. When the extrusion ball 18 moves to the position of the locking hole 8 opened on the left and right sides of the support 4, the extrusion ball 18 is locked in the inner wall of the locking hole 8. The friction and locking force restrict the rotation of the support rod 9, thereby fixing the support frame 7 at the target angle and ensuring that the music score is placed stably. Throughout the process, all components work together to achieve flexible adjustment and stable locking of height and angle.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
