Description

TECHNICAL FIELD

[0001] The utility model relates to a guitar polishing structure, especially to a center improved stepped polishing block for guitar fingerboard. BACKGROUND

[0002] Guitar polishing is an important process, involving surface treatment and smoothness improvement of guitar body, fingerboard, neck and other parts. Polishing not only improves the appearance of the guitar, but also affects the sound quality and playing comfort.

[0003] Today's polishing tools mainly include sandpaper, sand block, polisher, polishing cloth. Among these polishing tools, sandpaper is used to remove surface defects, old paint or old surface treatment. Sand block is used to keep sandpaper flat, suitable for polishing large area surface. Electric polisher can speed up the polishing speed, suitable for large area polishing. Electric polisher can speed up the polishing speed, suitable for large area polishing. Used for polishing and gloss treatment, making the surface smoother.

[0004] From this we can see that the existing polishing is divided into fine polishing and large area polishing, generally using sand block and polisher for large area polishing, and then using sandpaper and polishing cloth for fine polishing, but only using sandpaper for polishing, which is slow and needs manual pressing of sandpaper, making polishing difficult and leading to uneven guitar fingerboard and inaccurate guitar tone.

[0006] The upper polishing surface and the lower polishing surface are respectively located at the center positions of the upper side and the lower side of the body.

[0007] The side cross section of the upper polishing surface is a stepped structure.

[0008] The side cross section of the lower polishing surface is a stepped structure.

[0009] The side cross section of the upper polishing surface is an arc structure.

[0010] The side cross section of the lower polishing surface is an arc structure.

[0011] The side cross section of the upper polishing surface is two arc structures.

[0012] The side cross section of the lower polishing surface is two arc structures.

[0013] The upper polishing surface and the lower polishing surface are of the same structure.

[0014] The upper polishing surface and the lower polishing surface are of different structures.

[0015] The body, the upper polishing surface, the lower polishing surface, and the support end are of an integrated structure.

[0016] The polishing sandpaper is fixed on the upper polishing surface and the lower polishing surface through the adhesive layer.

[0017] The beneficial effects of the present application are as follows:

[0018] When the polishing block is used, the user can fully utilize the stepped design and the improved center to select appropriate height and angle according to different polishing tasks. This will improve the polishing efficiency and ensure the quality of wood surface treatment.

[0019] The use of the present application not only improves the multifunctionality of the product, but also provides the user with a more flexible, efficient, and balanced polishing experience.

[0020] The stepped design and the fixed center point are the innovative patent features of the present application. This design significantly improves the multifunctionality of the polishing block, making it convenient for the user to polish at different heights and angles to adapt to various wood surfaces and shapes.

[0021] The present application is an integrated structure except for the movable fixing of the sandpaper. The stepped structure not only provides multifunctionality, but also enhances the integrated shaping function of the polishing block. This means that the polishing block can better adapt to the contour of the wood, achieving a more delicate and uniform polishing effect.

[0022] The improved center position design of the present application allows the sandpaper to make more balanced contact with the wood surface. This design ensures that the wood surface can be subjected to uniform pressure and friction during polishing, thereby achieving a smoother and more consistent polishing effect.

[0023] The stepped design of the present application makes the polishing block suitable for various wood processing tasks, including but not limited to flat polishing, edge polishing, corner polishing, and complex curve polishing.

[0024] The present application has a thickness, and the support end is higher than the upper and lower polishing surfaces. When used, the user can hold the unused polishing surface. The ergonomic design allows the user to hold and use the polishing block more comfortably during polishing, especially when using the stepped structure for different angle polishing.

[0025] The center position is more stable, the sandpaper is fixed on the center of the utility model, the design ensures the stability of the sandpaper during use, and the stepped design allows the sandpaper to contact the wood surface at different heights, thereby improving the flexibility of polishing.

[0026] The utility model is generally made of wood material, the combination of high-quality wood and the stepped structure provides good durability and stability, so that the polishing block can maintain its shape and performance during long-term use.

[0027] The polishing sandpaper is of a detachable structure, and users can replace sandpaper of different grits according to different polishing requirements during use, so as to realize the whole process from coarse grinding to fine grinding. BRIEF DESCRIPTION OF DRAWINGS

[0033] Embodiment 1

[0034] The utility model discloses a modified stepped polishing block specially designed for polishing the fretboard of a guitar. The polishing block is composed of a whole body, which is equipped with an upper polishing surface and a lower polishing surface on the upper side and the lower side respectively, and a plurality of support ends. Four support ends are evenly distributed around each polishing surface, ensuring the stability and uniformity during polishing.

[0035] The upper polishing surface and the lower polishing surface are located at the center position of the body, forming a symmetrical polishing platform. The side surface of the upper polishing surface is ingeniously designed in a stepped shape, while the lower polishing surface adopts an arc structure. This design not only conforms to the natural curve of the guitar fretboard, but also improves the accuracy of polishing.

[0036] The body, the upper polishing surface, the lower polishing surface, and the support end form a tight integrated structure, enhancing the durability and consistency of the polishing block. The polishing sandpaper is firmly fixed on the upper polishing surface and the lower polishing surface through the adhesive layer, which not only ensures the long-term use of the polishing material, but also ensures the continuity and efficiency of the polishing process.

[0037] This improved stepped sanding block not only reflects a deep understanding of guitar fretboard sanding techniques, but also showcases an ingenious design philosophy in its details. It will undoubtedly provide guitarists with a more professional and efficient sanding experience.

[0038] Example 2

[0039] This invention relates to an improved stepped sanding block specifically designed for sanding guitar fingerboards. The sanding block consists of a single, integral body with an upper sanding surface and a lower sanding surface on its upper and lower sides, respectively, as well as multiple support ends. Four support ends are evenly distributed around each sanding surface, ensuring stability and uniformity during sanding. The side cross-sections of the upper and lower sanding surfaces are not identical. The upper sanding surface presents a combination of two arcs, while the lower sanding surface presents two independent arcs. This structural difference allows the sanding block to adapt to the sanding needs of different areas.
