Abstract
Description
Technical Field
[0001] This utility model relates to the field of erhu tuning peg technology, and more specifically to an erhu tuning peg structure. Background Technology
[0002] The tuning pegs of the erhu are used to adjust the pitch. By rotating them, the tension of the strings can be changed, thereby adjusting the pitch of the erhu.
[0003] However, the existing tuning pegs have the following main problems: 1) Since the strings pass directly through the small holes and are wound around the outer wall of the tuning peg, the strings are prone to loosening and causing them to go out of tune; 2) When tuning, in addition to turning the tuning peg, a fine tuner is required, which is inconvenient to operate and increases costs.
[0004] Therefore, providing a structure for the erhu tuning pegs that prevents the strings from slipping is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides a structure for the tuning pegs of an erhu, so as to at least solve one of the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A structure for an erhu (a two-stringed bowed instrument) has shallow and deep grooves distributed from the inside to the outside at the end of the shaft away from the grip, forming a main shaft for string winding and an auxiliary shaft for string winding in sequence; the main shaft for string winding has a string through hole; and there is a notch between the shallow and deep grooves for the string to pass through.
[0008] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:
[0009] After winding a small amount (1-2 turns) of string onto the string winding auxiliary shaft, it enters the shallow groove through the notch, passes through the string hole, and winds onto the string winding main shaft. This prevents the string from slipping back (loosening), ensures the string position, and avoids string slippage.
[0010] Furthermore, the shallow groove has a depth of 1mm and a width of 3mm; the deep groove has a depth of 3mm and a width of 1mm; thus, the diameter of the main shaft for winding the string is 8.5mm, and the diameter of the auxiliary shaft for winding the string is 4.5mm.
[0011] The beneficial effects of adopting the above-mentioned further technical solution are that the displacement of the string is small when the tuning peg rotates one revolution, improving the adjustment accuracy, eliminating the need for a fine tuner, making operation convenient and labor-saving, and reducing costs.
[0012] Furthermore, the notch is arranged at an angle.
[0013] The beneficial effect of adopting the above-mentioned further technical solution is that it facilitates the movement of the string from the deep groove to the shallow groove, while preventing the string from coming out of the notch.
[0014] Furthermore, the notch has a depth of 1 mm and a width of 1-2 mm.
[0015] Furthermore, the shallow groove has a chamfer near its end edge.
[0016] The beneficial effect of adopting the above-mentioned further technical solution is to prevent the strings from coming out of the shallow groove. Attached Figure Description

Obviously, the drawings described below are only embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1-2 As shown in the figure, this utility model discloses a structure for an erhu (a two-stringed bowed instrument) peg. The end of the peg 1 furthest from the grip 11 has shallow grooves 12 and deep grooves 13 distributed from the inside out, forming a main string winding shaft and an auxiliary string winding shaft in sequence. The main string winding shaft has a string through-hole 121. A notch 14 for the string to pass through is located between the shallow groove 12 and the deep groove 13. In this utility model, after a small amount (1-2 turns) of string is wound onto the auxiliary string winding shaft, it enters the shallow groove 12 through the notch 14, passes through the string through-hole 121, and winds onto the main string winding shaft. This prevents the string from slipping (loosening), ensuring the string position and preventing string slippage.
[0022] Specifically, the shallow groove 12 has a depth of 1mm and a width of 3mm; the deep groove 13 has a depth of 3mm and a width of 1mm; making the diameter of the main shaft for winding the string 8.5mm and the diameter of the auxiliary shaft for winding the string 4.5mm. In this way, the string displacement is small when the tuning peg 1 rotates one revolution, improving the adjustment accuracy, eliminating the need for a fine tuner, making operation convenient and labor-saving, and reducing costs.
[0023] To further optimize the technical solution of this utility model, the notch 14 is arranged at an angle. In this embodiment, the depth of the notch 14 is 1mm and the width is 1-2mm. This facilitates the entry of the string from the deep groove 13 into the shallow groove 12, while preventing the string from coming out of the notch 14.
[0024] To further optimize the technical solution of this utility model, the shallow groove 12 is chamfered near the end edge to prevent the strings from coming out of the shallow groove 12.
[0025] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
[0026] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
