Description

Technical Field

[0001] This utility model relates to the technical field of music score display racks, specifically a foldable music score display rack. Background Technology

[0002] Currently, sheet music display racks generally employ two mainstream structures for their page holders: The first is a foldable, telescopic linkage design. This structure uses multiple hinged linkages to form a support surface, enabling quick folding and storage. However, due to the numerous gaps between the linkages, it only provides partial support to the edges of the sheet music. This dispersed support method easily leads to the central collapse and deformation of thin sheet music during display, and the sheet music is prone to slipping out through the gaps between the linkages, especially with poor retention of single sheets. The second is a single-piece or bi-fold rigid panel design. While this provides even support to prevent the sheet music from slipping, the folding method is limited, typically only folding once along the center line. Even after folding, it still occupies a significant amount of space, making it difficult to meet the needs of portable storage. Therefore, there is an urgent need for a sheet music display rack that combines stable support with multi-directional folding capabilities. Utility Model Content

[0003] The purpose of this utility model is to provide a foldable music score display rack, which has the advantages of ensuring the music score is displayed flat while achieving compact storage, thus solving the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A foldable music score display stand includes a tripod support, with an adjustment rod rotatably connected to the top of the tripod support. The adjustment rod is equipped with a page frame composed of several page strips hinged together in sequence. Each side of the long side of two adjacent page strips is connected by a hinge. The adjustment rod has a groove along its length, which is open on both sides and at the top. A pivot is provided in the middle of the adjustment rod, which passes through the groove and also passes through the page strip located at the center point of the page frame.

[0006] The outermost page strip of the page frame is symmetrically hinged with a left support plate and a right support plate on both sides. The left support plate is slidably connected to a card plate through a first slide groove, and the right support plate is provided with a second slide groove at the corresponding position for the card plate to pass through.

[0007] Preferably, the four long edges of the page panel are all sloped, and the thickness of the hinge does not exceed the thickness of the page panel.

[0008] Preferably, multiple hollow slots are equidistantly provided on the page strip, and the left and right support plates are provided with hollow slots of the same specifications.

[0009] Preferably, the left and right support plates are connected to the page strip via two hinges, and the distance between the left and right support plates is equal to the width of the adjustment rod.

[0010] Preferably, the extension length of the first slide groove is not less than the length of the card plate, and the opening direction of the second slide groove is perpendicular to the first slide groove.

[0011] Preferably, the adjusting rod has a limiting step below the rotating shaft, and the step surface of the limiting step is in contact with the bottom surface of the card plate in the fully unfolded state.

[0012] Preferably, the groove is divided into a top groove and a bottom groove by the pivot, with the length of the top groove being greater than 1 / 2 of the width of the page frame and the length of the bottom groove being greater than 1 / 2 of the length of the page frame.

[0013] Preferably, a rotating wheel is fixed at the bottom of the adjusting rod. The rotating wheel is mounted on the top of the tripod via a toothed adjusting support. A rotating shaft that meshes with the rotating wheel passes through the adjusting support. One end of the rotating shaft that passes through the adjusting support is threaded to an internal threaded knob. Both sides of the rotating wheel and the inner sidewall of the adjusting support are provided with radially distributed teeth.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses multiple page panels that are hinged together in sequence, and with the groove and pivot design on the adjustment rod, it can achieve flat support and multi-directional roll-up storage of the page frame. When flat, all page panels are embedded in the groove to form a continuous support surface, avoiding the problem of hollow center in traditional linkage structures and preventing the sheet music from collapsing and deforming. When stored, the page frame can be rotated 90° around the pivot and then rolled up, greatly reducing the volume and saving more than 70% of space compared with traditional whole-panel folding.

[0016] 2. This utility model symmetrically sets a left support plate and a right support plate on the outermost page strip of the page frame. They are fixed by the sliding engagement of the plate and the slide groove. After the support plate is unfolded, it matches the width of the adjustment rod to form a full-width support for the bottom of the sheet music, preventing the sheet music from slipping. The plate is locked in a restricted position to ensure the stability of the support plate's support angle and increase the load-bearing capacity by more than 50%.

[0017] 3. In this utility model, the bottom end of the adjusting rod is connected to the adjusting support through a rotating wheel with radial teeth. With the help of a threaded knob, multi-angle stepless adjustment is achieved. The meshing of the teeth provides mechanical self-locking to prevent angle deviation during use. The stability is better than the traditional friction fixing method. The knob can be operated with one hand to complete the tightness adjustment, and the angle adjustment efficiency is improved by 40%.

[0018] 4. In this utility model, the page strip adopts a combination design of sloping edge and equidistant hollow groove. Combined with the thin layout of the hinge, the sloping edge makes the adjacent page strips fit together seamlessly when folded, reducing the folding radius to less than 3cm. The hollow groove reduces the amount of material used while ensuring strength, and the overall weight is reduced by 30%, significantly improving portability. Attached Figure Description

[0029] 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.

[0030] To address the issue of existing technologies failing to simultaneously provide stable support performance and multi-directional folding capability, the following technical solution is proposed. Please refer to [link / reference]. Figure 1-9 ;

[0031] A foldable music score display stand includes a tripod 1, the top of which is rotatably connected to one end of an adjusting rod 2. A page rack 10 is mounted on the adjusting rod 2, and the page rack 10 is composed of several page strips 3 arranged and combined.

[0032] The long sides of two adjacent page strips 3 are connected by hinges 4. Each side of two adjacent page strips 3 is provided with a hinge 4 to ensure the stability of the connection between the page strips 3. The thickness of the hinge 4 does not exceed the thickness of the page strip 3, and the four long edges of each page strip 3 are set as slopes 5. These two points can ensure that the page strips 3 can be rolled up at a large angle, thereby reducing the space occupied after rolling up.

[0033] The page strip 3 has equally spaced perforated grooves 13. The perforated grooves 13 can reduce the amount of raw materials used during the production of the page strip 3 and reduce the weight of the page strip 3 itself. At the same time, the page frame 10 is aesthetically pleasing and avoids a heavy feeling.

[0034] The adjusting rod 2 has a groove 6 extending along its direction. The groove 6 is open on both sides and the top. The adjusting rod 2 has a pivot 7 near the middle. The pivot 7 passes through the groove 6 and also passes through the center point of the page strip 3 located in the middle, so that the entire page frame 10 rotates around the pivot 7.

[0035] The groove 6 is divided into a top groove 8 and a bottom groove 9 with the pivot 7 as the dividing point. The length of the top groove 8 is greater than half the width of the page frame 10, so that when the page frame 10 is rotated to the horizontal extension state, the page strips 3 in the upper part are all engaged in the top groove 8 and thus supported by the adjustment rod 2. The length of the bottom groove 9 is greater than half the length of the page frame 10, so that the page frame 10 can pass smoothly through the bottom groove 9 without conflict when rotating.

[0036] Specifically, when the page frame 10 is rotated to the horizontally extended state, that is, when the extension direction of the page strip 3 is perpendicular to the extension direction of the adjusting rod 2, the page strips 3 are all locked in the grooves 6. The page strips 3 are flat due to the support of the adjusting rod 2 and the restriction of the grooves 6. At this time, the sheet music can be laid out on its surface for use. When storing, rotate the page frame 10 by 90° so that the extension direction of the page strips 3 is the same as the extension direction of the adjusting rod 2. At this time, except for the page strips 3 with the pivot 7, the other page strips 3 lose the support of the adjusting rod 2 and the restriction of the grooves 6 and hang down. At this time, the page frame 10 is rolled up for easy storage. Finally, elastic ropes or other ropes can be used to tie and bind the rolled-up page frame 10 to prevent it from falling apart.

[0037] The page strip 3 located at the outermost end has a support plate on its long side. The support plate includes a left support plate 11 and a right support plate 12. The left support plate 11 and the right support plate 12 are symmetrically distributed on both sides of the page strip 3. The left support plate 11 and the right support plate 12 are each connected to the page strip 3 through two hinges 4.

[0038] Both the left support plate 11 and the right support plate 12 are provided with a hollowed-out groove 13. The hollowed-out groove 13 of the left support plate 11 near the right support plate 12 is provided with a retaining plate 14. The retaining plate 14 is slidably connected to the left support plate 11 through a first sliding groove 15. The extension length of the first sliding groove 15 is not less than the length of the retaining plate 14, so that the retaining plate 14 can be completely retracted into the left support plate 11. The right support plate 12 is provided with a second sliding groove 16 in the hollowed-out groove 13 facing the left support plate 11 for the retaining plate 14 to pass through.

[0039] Specifically, when the page frame 10 is in a flat state, the left support plate 11 and the right support plate 12 are folded upwards until they are perpendicular to the plane of the page frame 10. At this time, the locking plate 14 is pulled so that its end passes through the first slide groove 15 into the second slide groove 16, so that the left support plate 11 and the right support plate 12 are engaged. Since the adjusting rod 2 is provided with a limiting step 17, when the locking plate 14 passes through the first slide groove 15, it fits against the step surface 18 of the limiting step 17. After the locking plate 14 connects the left support plate 11 and the right support plate 12, the locking plate 14 is restricted. The limiting function of position 17 prevents it from moving downwards, thus maintaining the left support plate 11 and the right support plate 12 at the current angle. After the sheet music is placed on the page holder 10, the left support plate 11 and the right support plate 12 support the bottom of the sheet music to prevent it from sliding down and falling. At the same time, the distance between the left support plate 11 and the right support plate 12 is equal to the width of the adjusting rod 2, so that the adjusting rod 2 limits the left support plate 11 and the right support plate 12, preventing the left support plate 11 and the right support plate 12 and the entire page holder 10 from tilting during use.

[0040] A rotating wheel 19 is fixed to the bottom of the adjusting rod 2. The rotating wheel 19 is mounted on the top of the tripod 1 via an adjusting support 20. An adjusting shaft 21 passes through the adjusting support 20 and through the rotating wheel 19. One end of the adjusting shaft 21 passes through the adjusting support 20 and is threaded into the internal threaded knob 22. The inner side wall of the adjusting support 20 and both sides of the rotating wheel 19 are provided with teeth, which are distributed radially. When it is necessary to adjust the angle of the adjusting rod 2, the knob 22 is loosened to reduce the clamping force of the adjusting support 20 on the rotating wheel 19. At this time, the adjusting rod 2 is pulled to adjust it to a suitable angle and then the knob 22 is tightened. Since the adjusting support 20 and the rotating wheel 19 are engaged, the connection stability is further ensured.

[0041] Working Principle: A foldable sheet music display stand, the page holder 10 is composed of multiple page strips 3, adjacent page strips 3 are connected by hinges 4, ensuring both a stable connection and flexible folding. The hollowed-out grooves 13 on the page strips 3 not only reduce the overall weight but also increase aesthetics. The adjusting rod 2 has grooves 6, which are divided into a top groove 8 and a bottom groove 9, and the page holder 10 is fixed to the adjusting rod 2 by a pivot 7, allowing the page holder 10 to rotate around the pivot 7. When the page holder 10 is unfolded to a horizontal state, the page strips 3 are locked in the grooves 6 and remain flat; when storing, the page holder 10 is rotated and rolled up for easy carrying. The outermost ends of the page strips 3 are provided with support plates, including a left support plate 11 and a right support plate 12, which are connected to the page strips 3 by hinges 4 and can be fixed to each other by a retaining plate 14 to support the sheet music and prevent it from slipping. In addition, the bottom of the adjusting rod 2 is equipped with a rotating wheel 19, and the angle can be adjusted by adjusting the support 20 and the internal thread knob 22 to ensure that the entire display rack can be stably maintained at the angle required by the user.

[0042] Before use, adjust the angle of the adjusting rod 2 according to your needs, and tighten or loosen the knob 22 to control the clamping force of the adjusting support 20 on the rotating wheel 19. Next, unfold the page holder 10 so that the page strip 3 is laid flat, and use the left support plate 11 and the right support plate 12 in conjunction with the clamping plate 14 to fix the sheet music. After use, roll up the page holder 10 for storage and tie it with rope to prevent it from coming apart. This saves space and makes it easy to move, solving the problem that traditional sheet music display racks are not easy to carry.
