SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a make axial and radial spacing nature better, avoid with the not hard up piano bass string of core string locating lever.
The technical scheme of the utility model is, provide a piano bass string with following structure, include by the core string that is rectangular type and the winding layer of being made by the copper product, the spiral of hugging closely about the winding layer is, the winding layer parcel is outside the core string, be equipped with the interval between the both ends tip on winding layer and the both ends tip of core string, the both ends of core string are equipped with around detaining: the method is characterized in that: the string winding device is characterized in that the end part of the core string is spirally wound from bottom to top in a multi-layer mode to form a winding buckle, a positioning strip is arranged at the top end of the winding buckle, and after the string winding device is installed on a string positioning rod, the positioning strip is bent, and the end part of the positioning strip is embedded into a positioning hole of the string positioning rod.
One part of the positioning strip is tightly attached to the outer part of the string positioning rod, and the end part of the positioning strip is embedded into the positioning hole of the string positioning rod and is abutted to the inner wall of the positioning hole.
The winding buckle and the central inner hole are conical, the upper part of the winding buckle is small, and the lower part of the winding buckle is large.
Wherein the outer diameter of the top end provided with the positioning strip is smaller than that of the bottom end.
The outer wall of the top of the string positioning rod is provided with a plurality of planes, and the planes are even and are symmetrical left and right.
The locating hole is the blind hole, and the degree of depth is greater than the radius of string locating lever.
After the structure more than adopting, the utility model has the advantages of it is following: because core string tip multilayer spiral from bottom to top and form around detaining, increase to multilayer structure to the area of being connected with the string locating lever is more, be equipped with the location strip around the top of detaining, after installing the string locating lever, the crooked and tip embedding of location strip is in the locating hole of string locating lever, and the embedding back location strip has realized axial and radial spacing with the string locating lever, has avoided the string not hard up.
As an improvement, one part of the positioning strip is tightly attached to the outer part of the string positioning rod, the end part of the positioning strip is embedded into the positioning hole of the string positioning rod and is abutted against the inner wall of the positioning hole, and after the positioning strip is tightly attached to and abutted against the inner wall of the positioning hole, the friction force between the positioning strip and the string positioning rod is increased.
As the improvement, all be big-end-up's taper shape around knot and central hole, the wall thickness of detaining is unanimous around, can laminate more with conical string locating lever.
As an improvement, the outer wall of the top of the string positioning rod is provided with a plurality of planes, the planes are even and are bilaterally symmetrical, and tools are convenient to mount.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-4, the utility model discloses a piano bass string, include by being rectangular core string 1 and the winding layer 2 of being made by the copper product, core string 1 generally be the musical instrument steel wire, the musical instrument steel wire has high tensile strength and better plasticity, and the circularity is good, the line footpath changes for a short time, winding wire 2 generally be the copper line. The winding layer 2 is in a spiral shape which is clung up and down, and the winding layer 2 is wrapped outside the core string 1. Be equipped with a sand grip and a recess on the core string 1 to two parallel equidistance winding, the outer wall of winding wire 2 after the winding offsets outside the outer wall of sand grip simultaneously adjacent other winding wire 2 outer wall embedding in the opening of recess 1 like this, thereby carries out axial spacing, greatly increased winding effect to the winding wire.
The two ends of the winding layer 2 are spaced from the two ends of the core string 1, and the two ends of the core string 1 are provided with winding buckles 1.1: the method is characterized in that: the end part of the core string 1 is spirally wound from bottom to top in a multilayer mode to form a winding buckle 1.1, a positioning strip 1.2 is arranged at the top end of the winding buckle 1.1, and after the winding buckle is installed on a string positioning rod 3, the positioning strip 1.2 is bent, and the end part of the positioning strip is embedded into a positioning hole 3.1 of the string positioning rod 3.
