Description

Piano bass string

Technical field

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

Background technology

Piano bass string is arranged on piano sympathetic response dish, is used for playing.A piano of the applicant's earlier application at present Bass string, including overspun wire main body, described overspun wire main body includes core string and the winding silk being wrapped on core string, described winding Silk ring-wound is formed on core string annular clad, described overspun wire body end be wound around silk end be wrapped in core string and Between annular clad.The described end being wound around silk is wrapped in the shape on core string in the shape of a spiral.The described end being wound around silk Portion is wrapped in the number of turns on core string and is at least two circles.After the other end bending of this core string is wound around in twisted shape after buckleing, in crimped end It is wound around in Extension Spring-type.Although the most this structure solve vibrations that bass string in use produces and be wound around silk itself The reason of tension force, can make the winding silk being wrapped on core string produce loose, and make bass string produce Sha Muyin in performance, make sound Matter is impaired.But yet suffer from following shortcoming: after being wound around in twisted shape after buckleing due to the other end bending of this core string, tightening up End is wound around in Extension Spring-type, understands some and extend at this after being wound around, and pricks the hand in the position so causing core string to stretch out；Additionally also It is particularly easy to encounter sympathetic response dish, thus causes the damage that sympathetic response dish paints.

Utility model content

The part that the technical problems to be solved in the utility model is stretched out after being to provide a kind of winding eliminating core string, it is to avoid Prick the hand and the piano bass string of paint on damage sympathetic response dish.

The technical solution of the utility model is to provide a kind of piano bass string with following structure, including overspun wire 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 formed on core string Annular clad, the end being wound around silk of described overspun wire body end is wrapped between core string and annular clad；Described core The afterbody twisted shape of string is formed around button at tail end after being wound around；End after described core string is wound around is neat with the lateral wall of this winding section Flat.

End after described core string is wound around is provided with bending edges, and this bending edges is towards being wound around section side.

The end of described bending edges is that semicircle is spherical.

It is provided with gap between the end of described bending edges with the winding bar of adjacent winding section.

The periphery of described winding section is flat.

After using above structure, this utility model has the advantage that the end after being wound around due to described core string twines with this Flushing around the lateral wall of section, the unnecessary core string that will originally stretch out is wiped out, and so can well avoid afterbody string to cause difficult to handle And.Unnecessary core string is wiped out, and is difficult to encounter sympathetic response dish, thus avoids damage to the paint on sympathetic response dish.

As improvement, the end after described core string is wound around is provided with bending edges, and this bending edges, can be more preferably towards being wound around section side Hiding end, it is to avoid stretch out and be wound around outside section.

As improvement, the periphery of described winding section is flat, prevents loose.

Accompanying drawing explanation

Fig. 1 is the structural representation of piano bass string of the present utility model.

Fig. 2 is the A portion enlarged diagram of Fig. 1.

Shown in figure:

1, core string, 1.1, be wound around section, 1.2, bending edges, 2, be wound around silk, 2.1, annular clad, 2.2, end.

Detailed description of the invention

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

As depicted in figs. 1 and 2, piano bass string of the present utility model, including overspun wire main body, described overspun wire main body includes Core string 1 and the winding silk 2 being wrapped on core string 1, described core string 1 generally piano wire, it is strong that piano wire has high anti-tensile Degree and preferable plasticity, and circularity is good, the change of line footpath is little, described winding silk 2 generally copper cash, described winding silk 2 annular Being wrapped on core string 1 formation annular clad 2.1, the end 2.2 being wound around silk 2 of described overspun wire main body section start 3 is wrapped in Between core string 1 and annular clad 2.1, the end 2.2 being wound around silk 2 it is wrapped in core string 1 and is wound around between silk 2, not only will twine The free end of wrapping wire 2 is fixed on core string 1 and is wound around between silk 2, and improves by being wound around the end 2.2 extruding winding silk 2 of silk 2 It is wound around the intermolecular forces of silk 2 and core string 1, makes to combine between winding silk 2 and core string 1 more stable, reduce being wound around silk 2 and produce loose Possibility, make bass string not send Sha Muyin in performance, and can be by being wound around silk 2 at overspun wire main body section start near terminal Side, place is wound around toward section start, reversely starts ring-wound and arrives overspun wire main body destination county, be completely wound after arriving section start.Institute Formed around buckleing 3 at tail end after stating the afterbody twisted shape winding of core string 1；The i.e. first bending of core string 1 is wound around in twisted shape again, during winding, The position of bending formation one around button 3, at the end that twisted shape is wound around, it is wound winding section in compressed spring type.

End after described core string 1 is wound around flushes with the lateral wall of this winding section 1.1.

End after described core string 1 is wound around is provided with bending edges 1.2, and this bending edges 1.2 is towards being wound around section 1.1 side.

The end of described bending edges 1.2 is that semicircle is spherical.

It is provided with gap between the end of described bending edges 1.2 with the winding bar of adjacent winding section 1.1.

The periphery of described winding section 1.1 is flat.
