Description

Technical Field

[0001] This utility model relates to the field of music equipment technology; more specifically, it relates to an adjustable-angle piano music stand. Background Technology

[0002] A music stand is a support used to hold sheet music. It is usually made of metal or wood and provides stable support, making it easy for the player to refer to the score while playing. The music stand is positioned in front of the piano, allowing the player to easily shift their gaze from the keys to the sheet music and maintain a good playing posture.

[0003] Currently, existing music stands are limited by the diverse sizes of sheet music and the relatively fixed structures of most music stands. This makes it difficult to place and support the sheet music according to its actual length, potentially causing the sides of the sheet music to lose support and reducing the applicability of the equipment. Furthermore, the fixed angle of most existing music stands makes it difficult for players of different heights to view the sheet music, requiring them to adjust their head posture and reducing the comfort of using the equipment. Therefore, there is an urgent need for an adjustable music stand to solve these problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable-angle piano music stand to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an adjustable-angle music stand, comprising:

[0006] The support plate has two sets, and the lower end of the support plate is hinged to a support base. The upper end of the support plate has a first sliding groove, and a movable slider is engaged inside the first sliding groove. A book clip is hinged to one side of the movable slider. The upper and lower ends of the surface of the two sets of support plates close to each other have a second sliding groove, and a sliding rod is engaged inside the second sliding groove. There are two sets of sliding rods. The outer surface of the upper end of one end of the support base is provided with a tension structure, and the outer surface of one side of the tension structure is provided with a connecting structure.

[0007] The tensioning structure includes a sleeve rod, and there are two sets of sleeve rods. The lower ends of the two sets of sleeve rods are respectively hinged to the outer surface of the upper end of one end of the two sets of support bases.

[0008] Preferably, the first slide groove is a T-shaped slide groove, the lower end of the movable slider is a T-shaped slider, and the internal dimensions of the T-shaped slide groove are adapted to the external dimensions of the T-shaped slider. A torsion spring is provided inside the hinge connection between the movable slider and the book clip. This design allows the T-shaped slider to move inside the first slide groove, and makes the movable slider more stable when moving. Furthermore, the torsion spring inside the movable slider and the book clip allows the book clip to hold the sheet music.

[0009] Preferably, the tensioning structure further includes a threaded rod, which is bearing-connected to the inside of the sleeve rod. A first bevel gear is fixedly connected to the lower outer surface of the threaded rod, and a second bevel gear is meshed with the outer surface of the first bevel gear. A rotating handle is fixedly connected to the outer surface of one end of the second bevel gear. A movable rod is sleeved on the outer surface of the threaded rod, and a support slider is hinged to the upper end of the movable rod. Two sets of support sliders are provided, and a third sliding groove is opened inside the rear surface of the two sets of support plates. One end of each set of support sliders is respectively engaged with the inside of the two sets of third sliding grooves. The outer surface of one end of the rotating handle penetrates and extends out of the inside of the sleeve rod. This design allows the movable rod to move up and down on the outer surface of the threaded rod when the rotating handle is rotated.

[0010] Preferably, the internal dimensions of the sleeve rod are adapted to the external dimensions of the moving rod, and the moving rod has a threaded groove inside, with the inner surface of the threaded groove adapted to the outer surface of the threaded rod. The third sliding groove is a T-shaped groove, and one end of the supporting slider is a T-shaped slider, with the internal dimensions of the T-shaped groove adapted to the external dimensions of the T-shaped slider at one end of the supporting slider. This design makes the moving rod more stable when moving inside the sleeve rod, and the T-shaped slider at one end of the supporting slider is more stable when moving inside the third sliding groove.

[0011] Preferably, the connecting structure includes telescopic rods, and there are two sets of telescopic rods. The inner threads of the outer surfaces of one side of the two sets of telescopic rods are connected to the clamping bolts, and the inner surfaces of the two sets of telescopic rods are inserted into the inner surfaces of the two sets of telescopic rods that are close to each other. The outer surfaces of the two sets of telescopic rods that are far from each other are respectively fixedly connected to the outer surfaces of the two sets of sleeve rods that are close to each other. This design allows the connecting structure to be adjusted according to the actual length of the musical score.

[0012] Preferably, the outer surfaces of both ends of the connecting rod are provided with limiting plates, and the outer dimensions of the limiting plates are adapted to the inner dimensions of the telescopic rod. Furthermore, the outer surface of one end of the tightening bolt abuts against the outer surface of one side of the connecting rod. This design makes the telescopic rod more stable when it moves outside the connecting rod. When it moves a certain distance, the limiting plates will prevent the connecting rod from detaching from the interior of the telescopic rod.

[0013] The technical effects and advantages of this utility model are as follows: By moving two sets of telescopic rods on the outer surfaces of both ends of the connecting rod, the two sets of tension structures can be moved outward or inward synchronously. This allows the support plate and the support base to move outward or inward synchronously, which makes it easier for the equipment to adjust according to the actual length of the sheet music and to place and support the sheet music. This improves the applicability of the equipment to a certain extent.

[0014] By rotating the handle, the second bevel gear rotates synchronously, driving the first bevel gear and the threaded rod to rotate. This causes the moving rod to move up or down on the outer surface of the threaded rod, which in turn pushes the support slider to move up or down inside the third groove. At this time, the support plate can be hinged to rotate outward or inward on the outer surface of the upper end of the support base. This makes it easier for players of different heights to read the sheet music without constantly adjusting their head posture while playing, thus improving the comfort of the equipment. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The musical instruments involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1-5 As shown, this embodiment proposes an adjustable-angle piano music stand, including:

[0024] Support plate 1, two sets of support plate 1 are provided, and support base 2 is hinged to the lower end of support plate 1. A first sliding groove 3 is provided at the upper end of support plate 1. A movable slider 4 is engaged inside the first sliding groove 3. A book clip 5 is hinged to one side of the movable slider 4. A second sliding groove 6 is provided at the upper and lower ends of the surface of the two sets of support plates 1 that are close to each other. A sliding rod 7 is engaged inside the second sliding groove 6. There are two sets of sliding rods 7. A tension structure 8 is provided on the outer surface of the upper end of one end of support base 2. A connecting structure 9 is provided on the outer surface of one side of tension structure 8.

[0025] The first slide 3 is a T-shaped slide, and the lower end of the movable slider 4 is a T-shaped slider. The internal dimensions of the T-shaped slide are adapted to the external dimensions of the T-shaped slider. A torsion spring is installed inside the hinge connection between the movable slider 4 and the book clip 5. This design allows the movable slider 4 to move inside the first slide 3, making the movable slider 4 more stable when moving. The position of the book clip 5 can be adjusted according to the actual situation of the sheet music. Then, the book clip 5 is supported by the elasticity of the torsion spring, so that the bottom surface of the book clip 5 can fit against the outer surface of the sheet music. Thus, the position of the sheet music is clamped and positioned by the support plate 1 and the book clip 5.

[0026] The connecting structure 9 includes a telescopic rod 91, and there are two sets of telescopic rods 91. The inner threads of the outer surface of one side of the two sets of telescopic rods 91 are connected to the clamping bolts 92. The inner threads of the two sets of telescopic rods 91 are inserted into the inner threads of the two sets of telescopic rods 91 at the ends close to each other. The outer surfaces of the two sets of telescopic rods 91 at the ends far from each other are respectively fixedly connected to the outer surfaces of the two sets of sleeve rods 81 at the ends close to each other. This design allows the two sets of telescopic rods 91 to be moved by moving the outer surfaces of the two ends of the connecting rods 93. At this time, the distance between the two sets of tension structures 8 and the support plate 1 can be adjusted according to the actual length of the sheet music. The sheet music can be placed on the outer surfaces of the two sets of support plates 1 and clamped. When the telescopic rods 91 are moved to a suitable position, their position can be fixed by rotating the clamping bolts 92.

[0027] The outer surfaces of the two sets of telescopic rods 91, which are far apart from each other, are fixedly connected to the outer surface of one side of the sleeve rod 81. This design makes the telescopic rods 91 more stable when they move on the outer surface of the connecting rod 93. The design of the limiting plate can prevent the telescopic rods 91 from detaching from the outer surface of the connecting rod 93 when they move, and limits the distance that the telescopic rods 91 can move.

[0028] Example 2

[0029] like Figure 3 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0030] The tension structure 8 includes a sleeve rod 81, and there are two sets of sleeve rods 81. The lower ends of the two sets of sleeve rods 81 are respectively hinged to the outer surface of the upper end of one end of the two sets of support bases 2.

[0031] The tension structure 8 also includes a threaded rod 82, which is bearing-connected to the inside of the sleeve rod 81. A first bevel gear 83 is fixedly connected to the outer surface of the lower end of the threaded rod 82. A second bevel gear 84 is meshed with the outer surface of the first bevel gear 83. A rotating handle 85 is fixedly connected to the outer surface of one end of the second bevel gear 84. A movable rod 86 is sleeved on the outer surface of the threaded rod 82. A support slider 87 is hinged to the upper end of the movable rod 86. There are two sets of support sliders 87. A third groove 88 is opened inside the rear surface of the two sets of support plates 1. One end of the two sets of support sliders 87 is respectively engaged with the inside of the two sets of third grooves 88. The outer surface of one end of the rotating handle 85 penetrates and extends out of the inside of the sleeve rod 81.

[0032] The internal dimensions of the sleeve rod 81 are adapted to the external dimensions of the moving rod 86, and the moving rod 86 has a threaded groove inside, and the internal surface of the threaded groove is adapted to the external surface of the threaded rod 82. The third slide groove 88 is a T-shaped groove, and one end of the supporting slider 87 is a T-shaped slider, and the internal dimensions of the T-shaped groove are adapted to the external dimensions of the T-shaped slider at one end of the supporting slider 87.

[0033] By rotating the handle 85, the second bevel gear 84 is driven to rotate, which in turn drives the first bevel gear 83 to rotate, and the threaded rod 82 rotates synchronously. This allows the moving rod 86 to move up or down on the outer surface of the threaded rod 82, making the movement of the moving rod 86 more stable. When the moving rod 86 moves, it pushes the support slider 87 to move up or down inside the third groove 88, making the movement of the support slider 87 more stable. At the same time, the support slider 87 is hinged to rotate, and simultaneously drives the support plate 1 to hinge to rotate on the outer surface of the upper end of the support base 2. Thus, the angle of the support plate 1 can be adjusted according to actual needs.

[0034] Working principle: When the device is in use, it can be placed on top of the piano. Rotate the clamping bolt 92 so that the surface of one end of the clamping bolt 92 no longer abuts against the outer surface of the connecting rod 93. According to the length of the sheet music, the two sets of telescopic rods 91 are stretched outward so that the two sets of telescopic rods 91 can respectively drive the two sets of support plates 1, support base 2 and tension structure 8 to move to both sides. At the same time, the second slide 6 moves to both sides on the outer surface of the slide rod 7. After the distance is adjusted, rotate the clamping bolt 92 in the opposite direction so that one end of the clamping bolt 92 abuts against the outer surface of the connecting rod 93 to fix the device position. Then the sheet music can be placed on the other end of the support base 2 so that the sheet music leans against the other side of the support plate 1. Move the sliding block 4 inside the first slide 3 to move the book clip 5 to the appropriate position. Then the book clip 5 is supported by the elasticity of the torsion spring so that the bottom surface of the book clip 5 abuts against the sheet music surface, thereby clamping and positioning the sheet music.

[0035] By rotating the handle 85, the second bevel gear 84 is driven to rotate, which in turn drives the first bevel gear 83 to rotate, and the threaded rod 82 rotates synchronously. This allows the moving rod 86 to move up or down on the outer surface of the threaded rod 82. When the moving rod 86 moves, it pushes the support slider 87 to move up or down inside the third groove 88, and simultaneously drives the support plate 1 to rotate outward or inward on the upper surface of the support base 2. Thus, the angle of the support plate 1 can be adjusted according to actual needs. The above is the complete working principle of this utility model.

[0036] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0038] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
