After the wireless page turning device is arranged, a player can conveniently turn pages in the playing process, the player can be ensured to concentrate on playing, and the performance quality is improved.
In order to better explain the wireless page turning method and the wireless page turning device, the concepts of the wireless page turning method and the wireless page turning device are better understood. As shown in fig. 1 and 2, a music score stand 10 includes: the page turning device comprises a base 100, an electric lifting device 200, a power supply device 300, a telescopic holder 400 and a wireless page turning device 500, wherein the electric lifting device 200, the power supply device 300 and the wireless page turning device 500 are respectively arranged on the base 100, and the telescopic holder 400 is arranged on the electric lifting device 200; it should be noted that the base 100 is used for fixing the whole music stand; one end of the electric lifting device 200 is fixed with the base 100, the other end of the electric lifting device 200 is fixed with the telescopic cradle head 400, and the electric lifting device 200 is used for lifting and adjusting the height of the telescopic cradle head 400 so as to reach a proper height and facilitate a player to play; the power supply device 300 is used for charging mobile equipment such as a tablet computer; the telescopic cradle head 400 is used for placing a music score; the wireless page turning device 500 is used for controlling the tablet computer to perform a wireless page turning operation. The invention relates to a music stand, which can be used for lifting the music stand in height and carrying out wireless control page turning operation by arranging an electric lifting device, a power supply device, a telescopic cradle head and a wireless page turning device, and can also be used for charging mobile equipment such as a flat plate; and because the cloud platform can stretch out and draw back and adjust, so can adjust according to the size of panel computer, can fix the dull and stereotyped of different sizes on the cloud platform steadily.
Further, referring to fig. 2, the existing base is designed by a large and thick steel plate because the existing base needs to support, and although the existing base can stably support, the whole music stand is heavy and inconvenient to move and carry, and the steel plate also occupies a large amount of space when the music stand is not used. Therefore, in order to reduce the weight of the base under the condition of ensuring the supporting function of the base, the base can have certain moving characteristic, the carrying is convenient, and meanwhile, when the music stand is not used, a large amount of space is not occupied. For example, the base 100 includes a bottom shell 110, a housing 120 and a fixing rod 130, the bottom shell 110 is connected to the housing 120, and the fixing rod 130 is rotatably disposed on the housing 120. It should be noted that the bottom case 110 is used for being placed on the ground to fix the whole music stand; the outer shell 120 is used for forming a certain protection cavity with the bottom shell 110; the fixing rod 130 is used to improve a supporting force for the base 100, so that the music stand can be more stably placed on the ground. In this way, by providing the bottom case 110 and the outer case 120, the base 100 can play a stable supporting role, and by providing the fixing rod 130, the fixing rod 130 can be rotatably disposed on the outer case 120, when the music stand is used, the fixing rod 130 can be rotated to the same horizontal plane as the bottom case 110, so that it can be ensured that the base can provide a stable supporting force, it should be noted that the fixing rod 130 is provided with a plurality of, preferably, the fixing rod 130 is provided with 3. When not using the music stand, rotate the back with dead lever 130, fold for dead lever 130 contracts, conveniently collects and deposits, like this, both alleviateed the weight of base, can let the base can have the characteristics of certain removal again, conveniently carries, does not also can not occupy a large amount of spaces when not using the music stand simultaneously.
It can be understood that, in order to ensure that the fixing rod 130 can be stably fixed on the ground without being retracted by external force, and at the same time, in order to ensure that the player can stably place the music score on the telescopic head, and in order to quickly perform the retracting operation when the fixing rod 130 needs to be retracted. For example, referring to fig. 3 and 4, the base 100 further includes a limiting assembly 140, the limiting assembly 140 includes a limiting elastic member 141 and a limiting block 142, the limiting block 142 is disposed on the housing 120, one end of the limiting elastic member 141 abuts against the housing 120, the other end abuts against the limiting block 142, and the limiting block 142 is clamped to one end of the fixing rod 130 close to the housing 120. Preferably, the limiting elastic member 141 is a spring or elastic rubber. Further, the limiting component 140 further includes a limiting fixing column 143, the limiting block 142 is provided with a limiting hole, the limiting fixing column 143 penetrates through the limiting hole, and two ends of the limiting column are fixed on the housing 120. Further, the fixing rod 130 is provided in plural, and the fixing rods 130 are respectively provided on the housing 120. Thus, can guarantee that dead lever 130 can be fixed subaerial steadily, can not shrink because of outside effort, also guarantee simultaneously that the player can place the music score on flexible cloud platform steadily to, when needs shrink dead lever 130, also can carry out the operation of getting up fast.
It should be noted that, in order to ensure the friction force between the fixing rod 130 and the ground, the stability of the base 100 is improved, and further, the stability of placing the music score on the music score stand can be provided, and the performance effect of the player is improved. For example, referring to fig. 2 and 3, the fixing rod 130 has a protection portion 131, the protection portion 131 includes a protection pad 131a and a protection installation tube 131b, the protection installation tube 131b is disposed on the protection pad 131a, and the protection installation tube 131b is sleeved on the fixing rod 130.
