Description

A kind of piano bass overspun wire

Technical field

This utility model relates to piano technical field, is especially a kind of piano bass overspun wire.

Background technology

Piano bass overspun wire is arranged on piano sympathetic response dish, is used for playing.There is a piano bass overspun wire at present, including twining String main body, described overspun wire main body includes core string and the winding silk being wrapped on core string, and described winding silk ring-wound is at core On string formed annular clad, described overspun wire body end be wound around silk end be wrapped in core string with annular clad it Between；The afterbody twisted shape of described core string is formed around buckleing at tail end after being wound around.The piano bass overspun wire of the most this structure exist with , so when the locating dowel of piano received by set, there is certain skidding probability in lower shortcoming: owing to the outer wall around button is smooth, Cause when factory assembles, around detaining slide relative with locating dowel, make troubles to practical set.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of avoiding makes bass overspun wire send out with the locating dowel on piano The raw piano bass overspun wire skidding, bringing convenience to practical set.

The technical solution of the utility model is to provide a kind of piano bass overspun wire with following structure, including overspun wire master Body, described overspun wire main body includes core string and the winding silk being wrapped on core string, and described winding silk ring-wound is on core string Forming annular clad, the end being wound around silk of described overspun wire body end is wrapped between core string and annular clad；Institute Formed around buckleing at tail end after stating the afterbody twisted shape winding of core string；It is positioned at the periphery wall around the core string 1 detaining 3 positions and is provided with some Annular groove 3.1.

Described around button groove outside be wound with nylon yarn layer.

Described nylon yarn layer is a line of whole.

The described cross section around button is long waist type.

After using above structure, this utility model have the advantage that due to described around button periphery wall be provided with some Bar annular groove, so set is when receiving the locating dowel on piano, groove good anti-slip can be had to make with the surface of locating dowel With, it is to avoid avoid making bass overspun wire skid with the locating dowel on piano, bring convenience to practical set.

As improvement, described being wound with nylon yarn layer outside the groove of button, skidproof effect is more preferable.

As improvement, described nylon yarn layer is a line of whole, and it is convenient to be wound around.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, piano bass overspun wire of the present utility model, including overspun wire main body, described twines String main body includes core string 1 and the winding silk 2 being wrapped on core string 1, and described core string 1 generally piano wire, piano wire has pole High tensile strength and preferable plasticity, and circularity is good, the change of line footpath is little, described winding silk 2 generally copper cash, described twines Wrapping wire 2 ring-wound forms annular clad 2.1 on core string 1, the end being wound around silk 2 of described overspun wire main body section start 3 2.2 are wrapped between core string 1 and annular clad 2.1, the end 2.2 being wound around silk 2 is wrapped in core string 1 and is wound around between silk 2, Not only the free end being wound around silk 2 it is fixed on core string 1 and is wound around between silk 2, and being wound around by being wound around end 2.2 extruding of silk 2 Silk 2 improves the intermolecular forces being wound around silk 2 with core string 1, makes to combine between winding silk 2 and core string 1 more stable, reduces and be wound around silk 2 produce loose possibility, make bass string not send Sha Muyin in performance, and can initiate in overspun wire main body by being wound around silk 2 Place is wound around toward section start near destination county side, reversely starts ring-wound and arrive overspun wire main body destination county after arriving section start, It is completely wound.The afterbody twisted shape of described core string 1 is formed around buckleing 3 at tail end after being wound around；It is positioned at outside the core string 1 detaining 3 positions Perisporium is provided with some annular grooves 3.1.

Described around button 3 groove 3.1 outside be wound with nylon yarn layer 4.

Described nylon yarn layer 4 is a line of whole.

The described cross section around button 3 is long waist type.
