Description

Technical Field

[0001] This utility model relates to the field of musical instrument polishing, and in particular to a flexible polishing pad. Background Technology

[0002] A flexible polishing pad for musical instruments is a tool used in the making and maintenance of musical instruments, primarily for sanding and polishing instrument surfaces. These pads are typically made of soft materials that conform to the curves and shapes of the instrument, ensuring evenness and precision during the polishing process.

[0003] Existing structures all use polishing cloths for polishing. Polishing cloths are relatively soft, but they have less support in detailed areas and narrow gaps, so they cannot polish well. Utility Model Content

[0004] In view of the above technical problems, the present invention provides a flexible polishing pad, characterized in that it includes a main body and polishing strips, wherein multiple polishing strips are provided on the upper side of the main body.

[0005] The grinding strip is semi-cylindrical in shape.

[0006] The grinding strips are all the same height.

[0007] The grinding strips have different heights.

[0008] The polishing strips are divided into high polishing strips and low polishing strips. High polishing strips are provided at both ends and the middle of the main body, and multiple low polishing strips are provided between every two high polishing strips.

[0009] A flexible polishing pad further includes a polishing structure and a handheld structure. The polishing strips at both ends of the main body are provided with mounting holes. The polishing structure is installed on the lower side of the main body through the mounting holes. The handheld structure is provided on the upper side of the main body.

[0010] The polishing structure is a polishing cloth.

[0011] The handheld structure consists of a mounting groove and a handheld part. The mounting groove is located on the lower side of the handheld part and is semi-cylindrical in shape. The mounting groove is compatible with the grinding strip structure.

[0012] The main body and the grinding strip are made of nylon-based resin material.

[0013] The main body and the polishing strip are made of EVA material.

[0014] The main body and the grinding strip have a thick-walled structure.

[0015] The widths of the grinding strips are different.

[0016] The polishing strips are all the same width.

[0017] The beneficial effects of this utility model are as follows: The surface of this utility model is designed with multiple small semi-cylindrical structures, and there is a large semi-cylindrical structure at each end and the center. This design not only increases the aesthetics of this utility model, but also provides a more stable grip when polishing curved surfaces, ensuring the stability and safety of the polishing process.

[0018] The main body and grinding strip of this utility model are made of nylon resin material, which has excellent wear resistance and impact resistance, while maintaining the product's lightweight.

[0019] By employing thick-wall forming technology, this invention achieves a more robust structure, reducing problems caused by bending or internal stress during use and improving the product's durability and reliability.

[0020] This utility model also includes a polishing structure and a handheld structure. The polishing structure is a polishing cloth, which is passed through the mounting hole of the main body and then tightened. During polishing, the user presses the polishing cloth to ensure that the polishing proceeds normally.

[0021] The lower side of the handle has a semi-cylindrical mounting groove that perfectly matches the structure of the polishing strip. When polishing a flat area with no curvature, the mounting groove is installed on the polishing strip. The user can pass their hand through the handle, making it easier for the user to apply more force, making the operation more convenient and the polishing effect better.

[0022] In addition to guitars, the design of this utility model also takes into account the polishing needs of other musical instruments such as ukuleles, demonstrating its forward-looking and applicable nature.

[0023] Due to its unique design and material selection, this invention is suitable for polishing various curved surfaces, especially in the field of musical instrument manufacturing and repair, and can provide a precise and efficient polishing experience.

[0024] This description highlights the main features of this utility model, including its patented design, material selection, size adaptability, thick-wall forming technology, and wide applicability, aiming to provide users with an efficient, stable, and durable grinding tool.

[0025] This utility model can be applied to the sanding of guitars and ukuleles in different sizes. Attached Figure Description

[0035] Example 1

[0036] This utility model proposes a flexible polishing pad, which consists of a main body and carefully arranged polishing strips, with multiple polishing strips evenly distributed on the main body.

[0037] The polishing strips are semi-cylindrical in shape, and each strip maintains the same height, ensuring stability and consistency in the polishing process. However, to meet different polishing needs, some strips are designed with varying heights, creating a staggered polishing effect.

[0038] This flexible polishing pad design not only improves polishing efficiency but also greatly enhances operational comfort and convenience. It will undoubtedly become a powerful tool in the field of precision machining, providing craftsmen with a more precise and efficient polishing experience.

[0039] Example 2

[0040] This invention proposes a flexible polishing pad, which consists of a main body and carefully arranged polishing strips, with multiple polishing strips evenly distributed on the main body. In the main body structure, high and low polishing strips are arranged alternately.

[0041] Example 3

[0042] This invention proposes a flexible polishing pad, which consists of a main body and carefully arranged polishing strips. Multiple polishing strips are evenly distributed on the main body. High polishing strips are provided at both ends and the middle of the main body, while multiple low polishing strips are interspersed between every two high polishing strips. This arrangement ensures both polishing depth and fineness.

[0043] Example 4

[0044] This invention proposes a flexible polishing pad, which consists of a main body and carefully arranged polishing strips, with multiple polishing strips evenly distributed on the main body. The pad also integrates polishing and handheld functions. Mounting holes are specially provided on the polishing strips at both ends of the main body, allowing the polishing structure—a highly efficient polishing cloth—to be securely mounted on the underside of the main body. Simultaneously, a user-friendly handheld structure is designed on the upper side of the main body, consisting of a mounting groove and a handheld part. The lower side of the handheld part has a semi-cylindrical mounting groove that perfectly matches the structure of the polishing strips. When polishing flat surfaces, the mounting groove is attached to the polishing strips, allowing the user to pass their hand through the handheld part, enabling greater force application, easier operation, and better polishing results.
