Description

Piano bass string
Technical field
The utility model relates to string, relates to a kind of piano bass string or rather.
Background technology
Piano bass string is arranged on piano allow, for playing.Current piano bass string comprises core string and is wrapped in the winding silk on core string, by core string and the tight winding being wound around silk, makes to produce bass when piano playing.The piano bass string of this structure has the following disadvantages above: the reason of the vibrations that bass string in use produces and itself tension force of winding silk, the winding silk be wrapped on core string can be made to produce loose, and make bass string in performance, produce Sha Muyin, make tonequality impaired.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and can will be wound around the piano bass string of silk stable winding on core string.
Technical solution of the present utility model is, a kind of piano bass string with following structure is provided, comprise overspun wire main body, described overspun wire main body comprises core string and is wrapped in the winding silk on core string, described overspun wire main body destination county is fixing by being wound around silk knotting, described winding silk ring-wound forms annular clad on core string, and the end of the winding silk of described overspun wire body end is wrapped between core string and annular clad.
After adopting above structure, piano bass string of the present utility model, compared with prior art, have the following advantages: the end being wound around silk be wrapped in core string and be wound around between silk, not only the free end being wound around silk be fixed on core string and be wound around between silk, and be wound around by the end extruding being wound around silk the intermolecular forces that silk improves winding silk and core string, make to combine between winding silk and core string more stable, reduce and be wound around the loose possibility of silk generation, bass string is made not send Sha Muyin in performance, and can be wound around toward section start near destination county side at overspun wire main body section start by being wound around silk, oppositely start ring-wound after arriving section start and arrive overspun wire main body destination county, complete winding, to realize structure of the present utility model.
End due to described winding silk of the present utility model is wrapped in shape on core string in the shape of a spiral, winding silk end is made to act on core string uniformly and be wound around on silk, what make to combine between winding silk and core string is more stable, and the canned paragraph of undulate is convenient to be wound around, and is convenient to processing.
Improve as one of the present utility model, the end of described winding silk is wrapped in the number of turns on core string and is at least two circles, ensure that the end being wound around silk effectively can act on core string and be wound around between silk, make winding silk not easily deforming displacement, and the end of winding silk can not be deviate from, make stable being wrapped on core string of winding silk energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of piano bass string of the present utility model.
Fig. 2 is A place enlarged drawing in Fig. 1.
Shown in figure: 1, core string; 2, silk is wound around; 21, annular clad; 22, the end of silk is wound around; 3, section start; 4, destination county.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to shown in Fig. 1 and Fig. 2, technical solution of the present utility model is to provide a kind of piano bass string with following structure, comprise overspun wire main body, the winding silk 2 that described overspun wire main body comprises core string 1 and is wrapped on core string 1, described core string 1 is generally piano wire, piano wire has high tensile strength and good plasticity, and circularity is good, wire diameter change is little, described winding silk 2 is generally copper cash, described winding silk 2 ring-wound forms annular clad 21 on core string 1, the end 22 of the winding silk 2 of described overspun wire main body section start 3 is wrapped between core string 1 and annular clad 21, the end 22 being wound around silk 2 be wrapped in core string 1 and be wound around between silk 2, not only the free end being wound around silk 2 be fixed on core string 1 and be wound around between silk 2, and the end 22 passing through to be wound around silk 2 extrudes the intermolecular forces that winding silk 2 improves winding silk 2 and core string 1, make to combine between winding silk 2 and core string 1 more stable, reduce winding silk 2 and produce loose possibility, bass string is made not send Sha Muyin in performance, and can be wound around toward section start 3 near destination county 4 side at overspun wire main body section start 3 by being wound around silk 2, oppositely start ring-wound after arriving section start 3 and arrive overspun wire main body destination county 4, complete winding, to realize structure of the present utility model.
End 22 due to described winding silk 2 of the present utility model is wrapped in shape on core string 1 in the shape of a spiral, winding silk 2 end 22 is made to act on core string 1 uniformly and be wound around on silk 2, what make to combine between winding silk 2 and core string 1 is more stable, and the canned paragraph of undulate is convenient to be wound around, and is convenient to processing.
Improve as one of the present utility model, the end 22 of described winding silk 2 is wrapped in the number of turns on core string 1 and is at least two circles, ensure that the end 22 being wound around silk 2 effectively can act on core string 1 and be wound around between silk 2, make winding silk 2 not easily deforming displacement, and the end 22 of winding silk 2 can not be deviate from, make stable being wrapped on core string 1 of winding silk 2 energy.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
