AI Technical Summary
The current string winding has a small contact area with the core wire, which makes the winding prone to loosening, affecting tone variation and causing finger slippage.
The core wire has a hexagonal cross-section and the winding wire has a regular hexagonal cross-section. The surface of the winding wire is rough, which increases the friction with the core wire, prevents the winding wire from loosening, and increases the friction when playing with fingers.
The increased friction between the wound thread and the core thread prevents the wound thread from loosening, maintains a stable tone, reduces finger slippage, and improves the stability and flexibility of playing.

Abstract
Description
Technical Field
[0001] This utility model relates to musical instrument accessories, and in particular to an anti-slip string. Background Technology
[0002] A musical string typically consists of a core wire and a spiral wound around it. For example, Chinese Patent Publication No. CN110517651A describes a string and its manufacturing method, which includes a string core and a spiral wound around it. The spiral wound comprises copper wire, a silver plating layer covering the surface of the copper wire, and a protective layer covering the silver plating layer. The protective layer is composed of a mixture of paint and metal powder. The spiral wound has a standard circular cross-sectional area, resulting in a small contact area between the spiral wound and the string core, meaning the adhesion of the spiral wound is relatively weak. After use at one end, the spiral wound is prone to loosening, causing changes in the string's tone and affecting the playing effect. Furthermore, the smooth surface of the spiral wound makes it easy for fingers to slip when playing. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an anti-slip string, thereby solving the technical problems existing in the prior art.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an anti-slip string, comprising a core wire and a spiral wound wire wound around the surface of the core wire, wherein the cross-section of the core wire is hexagonal and the cross-section of the spiral wound wire is regular hexagonal. The principle of this utility model is that the hexagonal spiral wound wire has a rough surface, resulting in greater friction between the spiral wound wire and the core wire, making it less prone to loosening and maintaining a consistent tone over a long period; furthermore, the rough surface of the spiral wound wire provides greater friction for finger playing, reducing finger slippage and allowing for more free and controlled playing.
[0005] As an improvement, the core wire is a hexagonal steel core, and the winding wire is a copper wire.
[0006] The beneficial effects of this utility model compared with the prior art are:
[0007] The hexagonal winding has a rough surface, resulting in greater friction between the winding and the core wire. This prevents the winding from loosening and helps maintain a consistent tone over a long period. Additionally, the rough surface of the winding provides greater friction for the fingers, reducing slippage and allowing for more precise and free playing. Attached Figure Description
[0008] Figure 1 This is a magnified view of a section of the strings.
[0009] Figure 2 This is a schematic diagram of the cross-section of the wound wire. Detailed Implementation
[0010] The present invention will be further described below with reference to the accompanying drawings.
[0011] like Figure 1 , 2 As shown, an anti-slip string includes a core wire 1 and a spiral wound wire 2 wound around the surface of the core wire 1. The core wire 1 has a hexagonal cross-section, and the spiral wound wire 2 has a regular hexagonal cross-section. The surface of the spiral wound wire 2 has six planes 21, with an angle 22 formed between adjacent planes 21. During winding, one plane 21 of the spiral wound wire 2 is visible in contact with the core wire 1. The core wire 1 is a hexagonal steel core, and the spiral wound wire 2 is a copper wire. The principle of this invention is as follows: the hexagonal spiral wound wire 2 has a rough surface, resulting in greater friction between the spiral wound wire 2 and the core wire 1. This prevents the spiral wound wire 2 from loosening and maintains its tone for a long time. Furthermore, the rough surface of the spiral wound wire 2 provides greater friction for finger playing, reducing finger slippage and allowing for more free and controlled playing.
