Description

Technical Field

[0001] This utility model relates to the field of harmonica technology, and in particular to a harmonica cover plate support block. Background Technology

[0002] The harmonica, with its small size and unique tone, has become a popular wind instrument. A harmonica generally consists of an upper cover plate, an upper spring plate, a fret, a lower spring plate, and a lower cover plate. The fret is located between the upper and lower spring plates, the upper cover plate is located on the outside of the upper spring plate, and the lower cover plate is located on the outside of the lower spring plate.

[0003] The gap between the cover plate and the reed plate plays a crucial role in sound propagation, volume enhancement, and tone improvement. This design not only improves the harmonica's playing performance but also enhances the user experience. Because the cover plate is primarily made of stamped metal less than 1 mm thick, and a gap is required between it and the reed plate, with only the bottom edge of the cover plate providing structural support, the cover plate is prone to collapse and deformation under pressure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this utility model is to provide a harmonica cover support block to solve the problems existing in the prior art. It has a simple structure and can effectively support the harmonica cover.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] This utility model provides a harmonica cover support block, such as Figures 1-5 As shown, it can be located between the spring plate and the cover plate, including: a support block and a positioning member. The support block has an inclined surface and a plane arranged opposite each other, a first surface and a second surface parallel to each other, and the first surface and the second surface are arranged perpendicular to the plane. The inclined surface and the plane both terminate at the first end and the second end opposite each other to form a shape that fits the assembly cavity between the spring plate and the cover plate. The positioning member can be detachably connected to the spring plate to define the position of the support block. The support block can fit well in the assembly cavity between the spring plate and the cover plate, providing stable support for the cover plate. At the same time, the inclined surface of the support block fits against the cover plate, and the plane fits against the spring plate, so that the support block can effectively support the cover plate and prevent the cover plate of the harmonica from easily collapsing and deforming after being squeezed.

[0030] In a preferred embodiment, the positioning element includes a positioning block integrally connected to the plane. The spring plate has a positioning hole or positioning groove, and the positioning block is fitted into the positioning hole or positioning groove. The integral connection of the positioning block to the plane increases structural stability. The engagement of the positioning block with the positioning hole or positioning groove on the spring plate allows for quick and accurate positioning of the support block, ensuring that the support block does not shift during use, thus providing better support for the cover plate.

[0031] In a preferred embodiment, both the positioning block and the positioning hole or positioning groove have rectangular cross-sections. The rectangular cross-section design makes the positioning block fit more tightly with the positioning hole or positioning groove, effectively preventing the support block from moving in the horizontal direction and improving the stability of the support.

[0032] In a preferred embodiment, the support block is made of glass fiber reinforced plastic (GFRP). GFRP has high strength and hardness, enabling it to withstand the pressure of the cover plate without deformation, thus providing reliable support for the cover plate. Simultaneously, this material exhibits good corrosion resistance and wear resistance, extending the service life of the support block.

[0033] In a preferred embodiment, the inclined surface and / or the flat surface of the support block transitions to the first and / or second surfaces, with the first and / or second ends connected by rounded chamfered edges. This rounded chamfered edge transition avoids injury to the user during installation and use, improving the harmonica's safety. Simultaneously, this design also makes the support block more aesthetically pleasing.

[0034] In a preferred embodiment, the support block is provided with a through hole, which is used for the first screw that fixes the cover plate and the guitar rack to pass through. The through hole facilitates the fixing of the cover plate and the guitar rack, and also plays a certain role in fixing the support block, making the support block more stable during use.

[0035] In a preferred embodiment, the support block is provided with a plurality of blind holes. The blind holes are used to accommodate the portion of the second screw that fixes the spring plate and the lever protruding from the spring plate. The plurality of blind holes provide a place for the portion of the second screw that fixes the spring plate and the lever protruding from the spring plate to pass through, effectively ensuring the fit between the plane and the spring plate.

[0036] In a preferred embodiment, the positioning element is a tear-off adhesive sheet. This easy-to-use adhesive sheet allows for quick and convenient fixing of the support block to the spring plate. Furthermore, when the support block needs to be replaced, it can be easily removed without damaging the spring plate.

[0037] Example 2

[0038] This embodiment also provides a harmonica, including a frame, two reeds, two cover plates, four first screws, multiple second screws, and four harmonica cover plate support blocks as described in any one of Embodiment 1. The two reeds are fixedly connected to both sides of the frame by the second screws. One cover plate is fixed to the outside of one of the reeds by two fourth screws. The four harmonica cover plate support blocks support both sides of the gap between the two sets of cover plates and the reeds. By setting four harmonica cover plate support blocks in the harmonica, the cover plates can be effectively supported, preventing them from collapsing and deforming under pressure, thus improving the overall stability and durability of the harmonica. At the same time, this structural design also makes the harmonica assembly more convenient and faster, improving production efficiency.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
