[0022] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.
[0023] As attached Figure 1 To Attachment Figure 6 As shown:
[0024] Embodiment 1: The utility model provides a roll-up music stand, including a storage assembly 1, the storage assembly 1 includes a storage tube 101, an expansion tube shaft 102 and an operating column 103, the expansion tube shaft 102 is rotatably connected to the inside of the storage tube 101, and the operating column 103 is inserted into the inside of the expansion tube shaft 102, and the top of the column of the operating column 103 passes through the storage tube 101; a split unfolding plate 2, one end of the split unfolding plate 2 is rotatably connected to the side of the expansion tube shaft 102.
[0025] In the disclosed embodiment, ten split unfolding plates 2 are provided, and the split unfolding plates 2 are in the shape of rectangular plates, and only one split unfolding plate 2 is rotatably connected to the side of the unfolding and folding cylinder shaft 102, and the other split unfolding plates 2 are rotatably connected to each other end to end in sequence. This design enables the split unfolding plates 2 to realize a roll-type unfolding structure through the storage component 1, and the split unfolding plates 2 can be wound around the outside of the unfolding and folding cylinder shaft 102 and hidden inside the storage cylinder 101, occupying a small space and being convenient to carry and carry, and when the split unfolding plates 2 are extended out of the storage cylinder 101, they can be automatically unfolded and straightened in sequence, which is convenient for the placement and practice of music scores, and the extension amount of the split unfolding plates 2 can be freely adjusted according to actual conditions or the size of the score paper.
[0026] In the embodiment of the present disclosure, a positioning top spring 1031 is provided inside the operating column 103, and the two ends of the positioning top spring 1031 are respectively against the inside of the operating column 103 and the inside of the stowage cylinder shaft 102, and a control gear 1032 is provided at the bottom of the operating column 103, and the insides of the stowage cylinder shaft 102 and the storage cylinder 101 are both provided with a control tooth groove 1021. When the operating column 103 is not pressed by an external force, the control gear 1032 is simultaneously inserted into the control tooth groove 1021 of the stowage cylinder shaft 102 and the storage cylinder 101. In use, the use state of the stowage cylinder shaft 102 can be positioned by the operating column 103, thereby stably maintaining the unfolded or retracted state of the split unfolding plate 2. The control gear 1032 of the operating column 103 can also lock the expansion and contraction cylinder shaft 102 through the control tooth groove 1021 of the expansion and contraction cylinder shaft 102, thereby positioning the split expansion plate 2 in the expanded and contracted state, and the stability is extremely strong.
[0027] When the cam 103 is in the open position, the spring 203 is engaged with the locking cam 104 and the locking cam 104 is engaged with the locking cam 104. When the cam 103 is in the open position, the locking cam 104 is engaged with the locking cam 104 and the locking cam 104 is engaged with the locking cam 104. The rear end side of the split unfolding plate 2 is provided with a limit slot 202. Under the cooperation of the limit card block 201 and the limit slot 202, the adjacent split unfolding plates 2 can be stretched straight to form a spliced plate shape, which is convenient for the placement and use of music scores. At the same time, according to the size of the music paper or the use requirements of the reagents, the number of split unfolding plates 2 pushed out and unfolded can be controlled to adapt to the use. It has strong flexibility and adaptability. After the split unfolding plates 2 are pushed out and unfolded for use in a suitable number of times, after releasing the operating column 103, the operating column 103 can automatically move up and reset to restore itself and the locking state of the unfolding cylinder shaft 102 under the action of the positioning top spring 1031, ensuring stable use. When the split unfolding plate 2 needs to be stored again, it only needs to press and reverse the operating column 103, and the split unfolding plate 2 can be rolled up again in sequence and stored only in the inside of the storage cylinder 101. The split unfolding plate 2 will automatically fold and avoid after hitting the inner wall of the storage cylinder 101, which is convenient to unfold and retract, and the regulation is fast and flexible.
[0028] The specific usage and function of this embodiment are as follows:
[0029] In the present invention, the use state of the stowage cylinder shaft 102 can be positioned by the operating column 103, so as to stably maintain the unfolded or retracted state of the split unfolding plate 2, avoid the phenomenon of accidental change of shape during carrying, transportation, transfer or use, and ensure stable use. When the operating column 103 is not pressed by external force, under the action of the positioning top spring 1031, the control gear 1032 is simultaneously inserted into the control tooth groove 1021 of the stowage cylinder shaft 102 and the storage cylinder 101, and the control tooth groove 1021 of the storage cylinder 101 locks the operating column 103 through the control gear 1032. The operating column 103 cannot be rotated, and the control gear 1032 of the operating column 103 can lock the stowage cylinder shaft 102 through the control tooth groove 1021 of the stowage cylinder shaft 102, thereby positioning the stowage state of the split deployment plate 2. When the split deployment plate 2 needs to be deployed for use, it is only necessary to press and rotate the operating column 103. After the operating column 103 is pressed, the control gear 1032 will escape from the control tooth groove 1021 of the storage cylinder 101 and compress the positioning top spring 1031. Thereafter, the locking state of the operating column 103 is released, and the control gear 1032 can be rotated when the operating column 103 is rotated. The expansion cylinder shaft 102 can be driven to rotate and push the split expansion plates 2 out of the storage cylinder 101 in sequence. After the split expansion plates 2 are pushed out of the storage cylinder 101, the split expansion plates 2 will be stretched straight against each other under the action of the expansion torsion spring 203, and the adjacent split expansion plates 2 can be stretched straight into a spliced plate shape under the cooperation of the limit card block 201 and the limit card slot 202, which is convenient for the placement and use of the music score. At the same time, according to the size of the music paper or the use requirements of the reagents, the number of the split expansion plates 2 pushed out and expanded can be controlled to adapt to the use, and the split expansion plates 2 can be pushed out and expanded for use in appropriate numbers. After releasing the operating column 103, the operating column 103 can automatically move up and reset under the action of the positioning top spring 1031 to restore itself and the locking state of the expansion and retraction tube shaft 102, ensuring stable use. After the music performance, training or learning is completed, the split expansion plate 2 can be stored again. When the split expansion plate 2 needs to be stored again, just press and reverse the operating column 103, and the split expansion plate 2 can be rolled up again in turn and stored only inside the storage tube 101. The split expansion plate 2 will automatically fold and avoid after hitting the inner wall of the storage tube 101, making it convenient to unfold and retract.
[0030] In another embodiment, the number of split expansion plates 2 is not limited to ten, and the number can be increased or decreased, further improving the adaptability of the device.
