Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

The automatic page turning device for the music sheet comprises a magnetic block 1, a turning rod 2, a copper sheet 3, a supporting seat 4, a bevel gear 5, a motor 6, a shell 7, a book spine 8, a transparent bag 9, an iron sheet 10, a pressing plate 11, a rope 12, a control chip and a control switch.

As shown in fig. 1, 2 and 3, the spine 8 is a U-shaped groove, two sides of the spine 8 are hinged to the housing 7, the housing 7 is a rectangular square plate made of plastic, two metal rings are arranged on the axis of the spine 8 and can be opened and closed in a rotating manner, a transparent bag 9 can be sleeved on the metal rings, the transparent bag 9 is a rectangular transparent bag made of plastic, two small holes are arranged on one side of the transparent bag 9 and are used for being mounted in the metal rings on the spine 8, iron sheets 10 are fixed on the upper right side and the lower right side of one surface of the transparent bag 9, copper sheets 3 are fixed on the other surface of the transparent bag 9 and opposite to the iron sheets 10 and used for separating magnetic force between the bags, a support seat 4 is mounted at one end of the housing 7, a rotating shaft is mounted in the support seat 4, a bevel gear 5 is mounted at one end of the rotating shaft, two turning rods 2 are fixed in parallel on the rotating shaft, 2 internally mounted of upset pole has rope 12, 12 rear ends of rope pass through elastic element with 2 internal connections of upset pole, 12 ends of rope are equipped with magnetic block 1, are provided with motor 6 on the shell 7, the output shaft of motor 6 passes through conical gear and the meshing of epaxial conical gear 5 of transmission. The outer end of the other shell 7 is provided with a pressing plate 11, the pressing plate 11 is made of flexible materials, and the extending end of the pressing plate 11 can press and fix the transparent bags 9 on the shell 7 on the side where the pressing plate 11 is located. The motor 6, the control chip, the control switch and the power supply are electrically connected.

The specific working principle is as follows:

when the multifunctional musical instrument is used, required musical instrument pages are placed in the transparent bags 9, the transparent bags 9 are fixed through the metal rings on the book spine 8, meanwhile, the transparent bags 9 are placed on the shell 7 on one side of the pressing plate 11, and the transparent bags 9 are clamped through the pressing plate 11. The forward rotation time, the stop rotation time and the reverse rotation time of the motor 6 are set according to the time required for looking at the music score when playing through the control switch and the control chip. Referring to fig. 1, when the motor 6 is operated in a forward rotation mode, the motor 6 drives the two turning rods 2 to rotate towards the right close to the housing 7 through the meshed pair of bevel gears 5, at this time, the elastic elements in the turning rods 2 enable the ropes 12 to be contracted inside the turning rods 2, and the two magnetic blocks 1 are exposed out of the outer ends of the turning rods 2. When the turnover rod 2 rotates to the horizontal position and is close to the transparent bag 9 on the right side, the two magnetic blocks 1 on the outer end of the turnover rod 2 are respectively attracted with the two iron sheets 10 on the transparent bag 9 on the top of the pressing plate 11. The horizontal position of the turnover rod 2 is the limit position of the forward rotation of the motor 6, then the motor 6 rotates reversely, the two turnover rods 2 rotate towards the direction away from the shell 7 leftwards, the magnetic block 1 on the turnover rod 2 attracts the iron sheet 10 on the transparent bag 9, the rotating turnover rod 2 pulls the transparent bag 9 to turn pages, along with the increase of the pulling force, the rope 12 in the turnover rod 2 is stretched out, and when the rope 12 reaches the limit length, the turnover rod 2 drives the transparent bag 9 to turn pages.

After the turning rod 2 rotates and pulls the transparent bags 9, the transparent bags 9 can be pulled apart at a certain dispersed angle, the distance from each transparent bag 9 to the edge of the pressing plate 11 is different, when the uppermost transparent bag 9 is pulled to the outer edge of the pressing plate 11, the pressing plate 11 made of flexible materials can separate the transparent bags 9 one by one, and the transparent bags 9 can be pulled out of the pressing plate 11 one by one.

Through the attraction of magnetic force piece 1 and iron sheet 10, upset pole 2 drives transparent bag 9 and turns left, when extreme position, the length of rope 12 is not enough to continue to drive transparent bag 9 and turns left promptly, two upset poles 2 are continuing to turn left this moment, the pulling force separates magnetic force piece 1 and iron sheet 10 this moment, transparent bag 9 falls down naturally to the shell 7 of spine 8 opposite side on, elastic element in the upset pole 2 makes rope 12 receive the line, motor 6 stall, accomplish the process of once automatic page turning. After the control chip controls the motor 6 to pause for a preset time, the forward rotation of the driving motor 6 is carried out again, and the page turning process is repeatedly realized.
