Description

Technical Field

[0001] The utility model relates to the technical field of electronic tuning equipment, and more specifically to a piano tuner with a Bluetooth transmission function. Background Art

[0002] The piano is a classic keyboard instrument, and the accuracy of its pitch is crucial to the performance effect. In order to maintain the accuracy of the pitch, the piano needs to be tuned regularly. Traditional tuning methods usually rely on artificial hearing, which may be more accurate for professionals, but may be difficult for ordinary users. In addition, with the digitalization of music production and performance, many musicians and enthusiasts hope to be able to tune on mobile devices.

[0003] With the advancement of technology, many automatic tuning devices have emerged, such as electronic tuners that support Bluetooth transmission. The tuner body is usually directly exposed to the outside without effective protection measures. This is not only easily affected by the external environment, such as dust and moisture, but also easily damaged by misoperation. In addition, traditional tuners are usually placed directly on the piano without providing stable support, which is not convenient to use. Utility Model Content

[0025] Example:

[0026] See also Figure 1-Figure 3 , a piano tuner with Bluetooth transmission function, comprising:

[0027] A protection box 1, two positioning frames 7 are fixedly connected to the inner walls on both sides of the protection box 1, two vertical rods 8 are movably penetrated through the upper inner wall of the protection box 1, the lower end of each vertical rod 8 is fixedly connected to a plug rod 9, a return spring 10 is fixedly connected between the top of each plug rod 9 and the upper inner wall of the protection box 1, the top ends of the two vertical rods 8 are fixedly connected to a connecting plate 11, the front outer surface of the protection box 1 is rotatably connected to a box cover 2, and the rear outer surface of the protection box 1 is rotatably connected to a supporting rear plate 14; and

[0028] The tuner body 5 has two outer surfaces on both sides thereof fixedly connected with fixing blocks 6 , and the two fixing blocks 6 are respectively slidably embedded in the two positioning frames 7 .

[0029] The two fixing blocks 6 are slidably embedded in the two positioning frames 7, and the two plugging rods 9 penetrate the two fixing blocks 6 to fix the tuner body 5 in the inside of the protection box 1. The protection box 1 and the box cover 2 also have a supporting back plate 14 to protect the fixing blocks 6 from falling. The box cover 2 is attached to the protection box 1 by magnetic attraction. The friction between the supporting back plate 14 and the protection box 1 is very large and can only be manually moved. The supporting back plate 14 can be opened to support the entire device as a support frame. It is only necessary to pull the connecting plate 11 upward to drive the two vertical rods 8 to move upward so that the two plugging rods 9 are separated from the two fixing blocks 6, and the tuner body 5 can be taken out from the inside of the protection box 1 for maintenance or repair. The tuner body 5 can be protected while the protection box 1 can be supported by the supporting back plate 14 for easy use.

[0032] Specifically, two limit rods 12 are fixedly connected between the top connection box 3 and the protection box 1 , and the connection plate 11 is slidably sleeved on the two limit rods 12 .

[0033] In this embodiment, the two limiting rods 12 enable the connecting plate 11 to move up and down stably.

[0034] Specifically, the upper end of the pull rod 13 is fixedly connected with a lifting ring 4 .

[0035] In this embodiment, the hanging ring 4 can better pull the pull rod 13, and can also hang the device.

[0036] Specifically, the pull rod 13 is located between the two limiting rods 12 .

[0037] In this embodiment, the two limiting rods 12 are distributed on both sides of the pull rod 13, which makes rational use of the installation space and is symmetrical and beautiful.

[0038] Specifically, each return spring 10 is slidably mounted on the corresponding vertical rod 8 .

[0039] In this embodiment, each return spring 10 is sleeved on the vertical rod 8, which makes rational use of the installation space and has an aesthetically pleasing distribution.

[0040] Working principle: the protection box 1, the box cover 2 and the supporting back plate 14 protect the fixed block 6 from falling. The box cover 2 is attached to the protection box 1 by magnetic attraction. The friction between the supporting back plate 14 and the protection box 1 is very large and can only be pried open manually. The supporting back plate 14 can be pried open and used as a support frame to support the entire device. It is only necessary to pull the hanging ring 4 to drive the connecting plate 11 to move upward through the pull rod 13, and drive the two vertical rods 8 to move upward, so that the two plug rods 9 are separated from the two fixed blocks 6, and the tuner body 5 can be taken out from the inside of the protection box 1 for maintenance or repair. It can protect the tuner body 5 while supporting the protection box 1 through the supporting back plate 14 for easy use. It is also very convenient to remove and install the tuner body 5 when it needs maintenance or repair, and it is highly practical.
