[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.
[0028] Please refer to Figures 1-4 The embodiment provides a music stand for chorus conducting, which comprises a support frame 100, and the support frame 100 is provided with a music stand 200 at the top, the music stand 200 is lifted, turned and inclined by the support frame 100, the height, angle and inclination range of the music stand 200 can be adjusted according to the situation of the conductor, and the comfort of chorus conducting is improved, wherein:
[0029] The music stand 200 comprises a clamping plate 210 which is detachably connected with the support frame 100, the clamping plate 210 is provided with support plates 220 for supporting music on both sides, the support plates 220 are provided with blocking plates 221 at the bottom, the side walls of the blocking plates 221 are provided with sliding grooves 222, two rotating shaft type sliding blocks 231 are slidably arranged in the sliding grooves 222, the outer walls of the two rotating shaft type sliding blocks 231 are rotatably provided with extrusion spring pieces 230, and the extrusion spring pieces 230 are used for generating inwardly converging extrusion force to fit and limit music, and the specific structure is as follows: Figures 1-2As shown, by sliding in the sliding groove 222 through the rotating shaft slider 231, the extrusion spring 230 can change position and also rotate the extrusion spring 230 to change the angle, realize the horizontal and vertical adjustment and control to adapt to the size of the music score, due to the material of the extrusion spring 230, the elastic force generated by the deformation can extrude the music score to limit the position, avoid accidental page turning during the chorus, at the same time, the two extrusion springs 230 block the front side of the music score, which can avoid the music score from sliding off the support plate 220 during the height and angle adjustment.
[0030] When adapting to the horizontal size of the music score, the rotating shaft slider 231 drives the extrusion spring 230 to slide until the extrusion spring 230 rotates to align with the position to be fixed and limited, which is beneficial to adapt to the horizontal size of the music score.
[0031] When adapting to the vertical size of the music score, the end of the extrusion spring 230 is rotationally connected with the rotating shaft slider 231 under the action of friction, and when subjected to external force, it rotates to overcome the friction until the extrusion spring 230 rotates to the position to be fixed and limited, and when the external force is withdrawn, the friction limits the relative rotation between the extrusion spring 230 and the rotating shaft slider 231.
[0032] Therefore, the improvement point of the utility model is that the extrusion spring 230 can adaptively move horizontally and rotate synchronously to ensure that the horizontal and vertical sizes of the music score are extruded and limited, improve the extrusion and fixation of the fixed point, improve the convenience, and the structure is simple and the cost is low.
[0033] On the basis of the above, the specific structure is further described.
[0034] Firstly, as shown in the drawings, Figure 3 The convex point is adapted and horizontally slides in the sliding groove 222, wherein:
[0035] The rotating sleeve at the end of the extrusion spring 230 is rotationally arranged on the outer wall of the rotating shaft slider 231, so that the rotating shaft slider 231 can stably horizontally slide in the sliding groove 222 without rotating, and the relative rotation between the extrusion spring 230 and the rotating shaft slider 231 is ensured to ensure the structural integrity.
[0036] In addition, the upper end of the extrusion spring 230 is inclined to the surface of the support plate 220 and is fixedly connected with a rubber pad, which realizes the outward swinging of the extrusion spring 230 to make it deform under stress, and when the external force is withdrawn, the end of the extrusion spring 230 can reset to extrude and limit the music score, improve the limiting strength, and at the same time, the rubber pad reduces the hard abrasion damage.
[0037] Then, when the distance between the two extrusion springs 230 is adjusted to a suitable position, in order to limit the position and prevent the music score from becoming unstable due to shaking, multiple limiting screw holes 223 are provided at equal intervals inside the slide groove 222. The outer wall thread of the pivot slider 231 passes through the limiting screw 232, and the limiting screw 232 is threadedly connected to one of the limiting screw holes 223. When it is necessary to move the distance between the two extrusion springs 230, the limiting screw 232 is screwed out from one of the limiting screw holes 223, so that the pivot slider 231 is released from the limit and moves horizontally. When it moves to a suitable position, the limiting screw 232 is aligned with the other limiting screw hole 223 and screwed in to limit the pivot slider 231, that is, to prevent the extrusion springs 230 from sliding left and right at will.
[0038] Furthermore, such as Figure 4 As shown, to enable the support frame 100 to support and adjust the height of the music score holder, the support frame 100 first includes a triangular support leg 110. A telescopic rod 120 for changing the height is fixedly connected to the center of the top of the triangular support leg 110. The telescopic rod 120 can be changed in length by screwing in bolts or by using a multi-stage sleeve structure to change the length, thereby enabling the music score holder 200 to change its height and ensuring that the triangular support leg 110 is stably supported on the ground.
[0039] Specifically, each of the triangular ends of the triangular support leg 110 is equipped with a rubber pad 111. The rubber pad 111 generates adaptive elasticity to keep the music score platform 200 level. When the ground is uneven or contains impurities, the rubber pad 111 can be squeezed for adaptive compression, which helps to keep the music score platform 200 stable and level. At the same time, the elastic rubber material of the rubber pad 111 has high frictional resistance when in contact with the ground, reducing the possibility of slippage.
[0040] When the angle and tilt range need to be adjusted, the support frame 100 also includes a universal joint 130 rotatably mounted at the end of the telescopic rod 120. A fixed frame 140 is sleeved on the outer wall of the universal joint 130. The universal joint 130 and the fixed frame 140 are rotatably connected and are threadedly locked through the universal joint 130 and the fixed frame 140 by a locking screw 131 passing through the interior of the universal joint 130 and the fixed frame 140. When the angle needs to be changed, the universal joint 130 can be manually rotated to drive the music score holder 200 to change the angle. The frictional resistance of the rotating shaft connected to the end of the universal joint 130 and the telescopic rod 120 can limit the required angle. In actual choral conducting, the probability of the sheet music placement platform 200 turning arbitrarily is low. Therefore, a conventional rotating shaft connection is used. When it is necessary to adjust the tilt range, the locking screw 131 is screwed out to allow the fixed frame 140 and the universal joint 130 to tilt at any angle. When rotated to a certain angle, the locking screw 131 is threaded through the fixed frame 140 and the universal joint 130 to lock them in place. Since the sheet music is placed on the support plate 220 with weight, the downward gravity of the sheet music can easily cause the tilt range to be compromised. Therefore, the locking screw 131 is used to lock the position firmly to improve stability.
[0041] It is worth noting that, since the sheet music stand 200 is easily damaged by prolonged use or striking, and different sheet music can use different support plates 220, in order to facilitate the customized installation of the sheet music stand 200 according to the conductor's needs, a lower support plate 141 is fixedly connected inside the fixed frame 140 near the bottom, and an upper support plate 142 is slidably connected inside the fixed frame 140 near the top.
[0042] The top of the upper support plate 142 is threaded with a clamping screw 143. The end of the clamping screw 143 is threaded into the inside of the fixing frame 140. By rotating the clamping screw 143 and the upper support plate 142, the upper support plate 142 and the lower support plate 141 are kept aligned. At the same time, the distance of the clamping screw 143 bolt into the fixing frame 140 can be adjusted to control the distance between the upper support plate 142 and the lower support plate 141. This allows for clamping and fixing of different sized clamping plates 210, and is easy to disassemble. It is convenient to install a conventional or this solution's music score holder as needed, and is easy to adapt to the conductor's habits.
[0043] In practical use, the music score holder for choral conductors of this utility model is stably supported on the ground by the triangular support legs 110. The telescopic rod 120 drives the music score placement platform 200 to change height. Manual force rotation causes the universal bracket 130 to drive the music score placement platform 200 to change angle. By screwing out the locking screw 131, the fixed frame 140 and the universal bracket 130 can be tilted at any angle. When rotated to a certain angle, the locking screw 131 is threaded through the fixed frame 140 and the universal bracket 130 to lock them until a comfortable position for the conductor is achieved.
[0044] By rotating the screw 143 and the upper support plate 142 together until they are aligned, and adjusting the distance between the upper support plate 142 and the lower support plate 141, the clamping plate 210 is positioned between them for clamping and fixing. Then, the sheet music is placed on the support plate 220, and the rotating slider 231 drives the compression spring 230 to slide until the compression spring 230 rotates to align with the position to be fixed on the sheet music, adapting to the lateral size of the sheet music. It is rotated by external force to overcome friction until the compression spring 230 rotates to the position to be fixed, thus achieving the compression and fixing of the fixing point.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
