Description

Technical Field

[0001] The utility model belongs to the technical field of harmonicas, and particularly relates to a disassembly and assembly structure for an easily disassembled high-pitch heavy harmonica. Background Art

[0002] The accent harmonica is a harmonica that takes the advantages of both monophonic and polyphonic. Each hole is also divided into two sections, but the sound of the lower section is twice as high as the upper section. The sound is very elegant and pleasant, and is very suitable for duets, trios, and large ensembles. When it was first invented, ten holes were the most common, and each hole was equipped with two reeds, one for blowing and one for sucking. (The harmonicas produced by various Japanese harmonica factories also have 20 holes, 21 holes, 24 holes, etc. Its structure is the same as that of the polyphonic harmonica. It can produce 24 notes, with 2-3 sections on one line. The number of sections on one line can produce songs of several parts.

[0003] The existing technology has the following problems:

[0004] 1. The existing heavy harmonicas on the market often have a simple structure, and the disassembly work is cumbersome, which is not convenient for cleaning and maintenance;

[0005] 2. After long-term playing, impurities in the oral cavity of the existing heavy harmonicas on the market may enter the mouthpiece of the heavy harmonica, and the mouthpiece is not easy to disassemble, so that the player cannot replace the mouthpiece easily and quickly, which reduces the service life of the harmonica.

After the replacement and maintenance are completed, it can be installed in turn.

[0034] Example 2

[0035] like Figure 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, threaded rods 9 are threadedly connected to the inner sides of the side edges of the cover plate 1 and the seat plate 5, and the threaded rods 9 are symmetrically arranged with respect to the vertical center line of the fret 3. A turntable 10 is fixedly connected to the upper surface of the threaded rod 9, a fixing block 11 is fixedly connected to the lower surface of the threaded rod 9, and a rubber protection layer 12 is fixedly connected to the lower surface of the fixing block 11. A filter plate 13 is movably connected to the front surface of the fret 3. Installation grooves 14 are formed inside the filter plate 13, and the number of the installation grooves 14 is multiple and the multiple installation grooves 14 are arranged horizontally. A filter net 15 is movably inserted into the installation grooves 14, and the sizes of the filter net 15 and the installation grooves 14 match each other.

[0036] In this embodiment, by rotating the turntable 10 to drive the threaded rod 9 to rotate, the two fixing blocks 11 and the rubber protection layer 12 are driven to move in the same direction, so as to clamp the fret 3 separately, realizing quick installation. And by adjusting the fixing blocks 11 and the rubber protection layer 12, the problem of different sizes of the fret 3 can be avoided. By driving the two fixing blocks 11 and the rubber protection layer 12 to move in opposite directions, the disassembly of the fret 3 can be quickly completed, which is convenient for the subsequent maintenance and cleaning of the device. By arranging the installation grooves 14 inside the filter plate 13, it is convenient to install the filter net 15 subsequently. By installing the filter net 15, impurities can be effectively prevented from entering the internal part of the tremolo harmonica, which can make the device have a good dust-proof effect and extend the service life of the tremolo harmonica. Its structure is simple.

[0037] Embodiment 3

[0038] As Figure 1-5 shown, on the basis of Embodiment 1 and Embodiment 2, the present utility model provides a technical solution: Preferably, a mouthpiece 16 is movably connected to the front surface of the filter plate 13. Installation holes 17 are formed on the side surface of the mouthpiece 16. A fixing screw 18 is threadedly connected to the inside of the installation holes 17. The fixing screw 18 is threadedly connected to the inside of the fret 3 through the upper installation holes 17 and the filter plate 13. An upper protection plate 19 is fixedly connected to the upper surface of the cover plate 1, and a lower protection plate 20 is fixedly connected to the lower surface of the seat plate 5. The upper protection plate 19 and the lower protection plate 20 are symmetrically arranged with respect to the vertical center line of the fret 3.

[0039] In this embodiment, since the fixing screw 18 is threadedly connected to the inside of the fret 3 through the upper installation holes 17 and the filter plate 13, the detachable connection between the filter plate 13 and the fret 3 is realized, which is convenient for the disassembly and assembly of the filter plate 13, convenient for the subsequent maintenance and cleaning of the device, and easy to clean. The upper protection plate 19 and the lower protection plate 20 can provide a certain buffering and shock-absorbing effect for the harmonica body when the harmonica body accidentally drops, thereby protecting the tremolo harmonica, improving the protection performance of the tremolo harmonica, and optimizing the structural performance of the tremolo harmonica.

When it is necessary to install and maintain the tremolo harmonica, the nut 8 on the bolt 7 in the movable groove 6 is disassembled. At this time, after the cover plate 1 and the seat plate 5 are freely separated, the cover plate 1, the upper reed plate 2, the fret 3 and the lower reed plate 4 can be taken off in sequence, which makes the device easy to disassemble and install, improving the efficiency of installation and disassembly during work. By rotating the turntable 10 to drive the threaded rod 9 to rotate, two fixing blocks 11 and the rubber protective layer 12 are driven to move in the same direction, so as to clamp the fret 3 alone, realizing rapid installation. And by adjusting the fixing blocks 11 and the rubber protective layer 12, the problem of different sizes of the fret 3 can be avoided. By driving the two fixing blocks 11 and the rubber protective layer 12 to move in the opposite direction, the disassembly of the fret 3 can be quickly completed, which is convenient for subsequent maintenance and cleaning of the device. By installing the filter net 15, impurities can be effectively prevented from entering the inside of the tremolo harmonica, making the device have a good dust-proof effect and prolonging the service life of the tremolo harmonica. Its structure is simple. The fixing screw 18 is threadedly connected to the inside of the fret 3 through the upper mounting hole 17 and the filter plate 13, making the detachable connection between the filter plate 13 and the fret 3, which is convenient for the disassembly and assembly of the filter plate 13, subsequent maintenance and cleaning of the device, and easy to clean. The upper protective plate 19 and the lower protective plate 20 can provide a certain buffering and shock-absorbing effect for the harmonica body when the harmonica body accidentally falls, thus protecting the tremolo harmonica, improving the protection performance of the tremolo harmonica, and optimizing the structural performance of the tremolo harmonica.
