Description

Technical Field

[0001] The utility model relates to the technical field of hair installation of a stringed instrument bow, in particular to a hair fixing device for the end of a tailpiece of a bow. Background Art

[0002] A bow is an important tool for playing stringed instruments. It usually consists of a bow stick and bow hair. The bow stick is generally made of wood, while the bow hair is mostly made of horsehair because horsehair has good elasticity and grip, which can better control the vibration of the strings and thus produce pleasant sounds. The material and manufacturing process of the bow have a direct impact on the playing effect. Therefore, it is crucial for players to choose a suitable bow.

[0003] For a bow to produce wonderful sounds, its hair must be firmly fixed. In traditional bows, the hair is fixed at the end of the tailpiece by inserting a wooden wedge into the gap between the hair and the inner wall of the tailpiece at the end of the tailpiece. Since a metal semi-circular ring is also sleeved outside the end of the tailpiece, the hair is tightly clamped in the middle after the wooden wedge is inserted (as shown in Figure 1 ). The wooden wedge is relatively small and is basically hand-carved. When inserting the wooden wedge into the tailpiece, the tip of the wooden wedge is first manually inserted into the gap at the end of the tailpiece, and then the tail of the wooden wedge is tapped with a hammer to completely insert the whole wooden wedge into the tailpiece.

[0004] This manual manufacturing method is likely to result in non-standard sizes of the wooden wedges. Therefore, there will inevitably be a certain gap between the wooden wedge and the inner wall of the metal semi-circular ring at the end of the tailpiece. During the performance, when pulling the bow, the horsehair may move horizontally under the tension, so it may get into the gap between the wooden wedge and the end of the tailpiece, resulting in loose fixation of the horsehair and affecting the playing effect. Seriously, it may also cause the horsehair to break due to the change of the friction angle, affecting the service life of the bow. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a hair fixing device for the end of a tailpiece of a bow, which solves the problem that the horsehair in the prior art may enter the gap between the wooden wedge and the end of the tailpiece, resulting in affecting the playing effect and the service life of the bow.

[0006] According to an embodiment of the present utility model, a fixing device for the hair of a violin bow tailpiece end includes the end of the violin bow tailpiece and a fixing block arranged inside the end of the violin bow tailpiece. The end of the violin bow tailpiece includes a closed cylindrical structure formed by combining a flat plate and a semi-circular ring plate. One end of the hair of the bow extends into the interior of the end of the violin bow tailpiece for fixation, and the other end extends out of the end of the violin bow tailpiece and extends to the head of the violin bow. The fixing block is a sheet-shaped plastic profile, one side of which is horizontal, and the middle of the other side inclines towards one end to form a connected horizontal section and a contraction section, which together form a wedge-shaped structure. On both sides of the fixing block, gaskets protruding outwards are provided at the end edges corresponding to the side in contact with the hair of the bow. The gaskets are elastic structures, and the length of the gaskets is not greater than the thickness of the fixing block. The width of the fixing block is only slightly smaller than the inner diameter of the semi-circular ring plate of the end of the violin bow tailpiece.

[0007] Further, the gasket is parallel to the surface of the fixing block in the normal state, so that it is perpendicular to the side surface of the fixing block to which it is connected.

[0008] Further, the middle of the gasket protrudes slightly towards the side in contact with the hair of the bow, so that the outer end of the gasket inclines towards the side of the fixing block away from the hair of the bow.

[0009] Further, a plurality of anti-slip lines are provided on the surface of the gasket close to the hair of the bow, and the anti-slip lines are arranged perpendicular to the direction of the hair of the bow.

[0010] Further, a concave limiting groove is provided on the surface of the fixing block corresponding to the hair of the bow. The depth of the limiting groove corresponds to the thickness of the hair of the bow. The edge of the limiting groove is inclined outwards and connected to the two side edges of the surface of the fixing block, so that the limiting groove is a trapezoidal groove.

[0011] Further, the connection between the contraction section and the horizontal section of the fixing block is an arc surface.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] Gaskets protruding outwards are provided on both sides of the fixing block of the present utility model. The gaskets are elastic structures, and the length of the gaskets is not greater than the thickness of the fixing block. Therefore, after the fixing block is inserted into the end of the violin bow tailpiece, the gaskets will be embedded between the two sides of the fixing block and the inner side surface of the semi-circular ring plate. Because the gaskets are elastic structures, when the fixing block is inserted inwards and the horsehair is pressed tightly due to the extrusion of the semi-circular ring plate by its wedge-shaped structure, the gaskets are also continuously squeezed and deformed, so as to completely fill the gap existing between the fixing block and the semi-circular ring plate. In this way, during the playing process, even if the horsehair is stressed and moves horizontally, it will be blocked by the gaskets and cannot enter the gap, but is always pressed tightly by the fixing block and the flat plate, thus maintaining the fixing effect of the horsehair, preventing loosening or breakage due to wear, and maintaining the playing quality and service life of the violin bow.

[0019] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0020] As shown in Figure 2 As shown, an end head horsehair 1 fixing device for a violin bow tailpiece in the embodiment of the present utility model includes an end part 5 of the violin bow tailpiece and a fixing block 6 arranged inside the end part 5 of the violin bow tailpiece. The end part 5 of the violin bow tailpiece includes a closed cylindrical structure formed by combining a flat plate 51 and a semi-circular ring plate 52. One end of the horsehair 1 extends into the inside of the end part 5 of the violin bow tailpiece for fixation, and the other end extends out of the end part 5 of the violin bow tailpiece and extends to the head of the violin bow.

[0021] As shown in Figure 4 As shown, in this embodiment, the fixing block 6 is a sheet-shaped plastic profile, and the middle part of the other side is inclined towards one end to form a horizontally connected horizontal section 61 and a shrinkage section 62, which together form a wedge-shaped structure. Similarly, it cooperates with the semi-circular ring plate 52 of the end part 5 of the violin bow tailpiece. The thinner end of the shrinkage section 62 can freely extend into the inside of the semi-circular ring plate 52 near the flat plate 51. When the thickness of the extended part of the shrinkage section 62 gradually increases, it will contact the inner wall of the semi-circular ring plate 52, and thus be pressed tightly on the flat plate 51 to fix the horsehair. In addition, the connection between the shrinkage section 62 and the horizontal section 61 of the fixing block 6 is an arc surface, so as to reduce the local friction caused by the connection to the horsehair, expand the contact surface, and avoid damage to the horsehair leading to breakage.

[0022] Preferably, in this embodiment, plastic is used to prepare the fixing block 6. Therefore, it can be mass-produced by an injection molding process. In this way, the production speed of the fixing block 6 is much faster than the traditional method of manually preparing the wooden wedge 4, and the size and shape are more standard and unified, and the cost is also lower.

[0023] In this embodiment, gaskets 7 protruding outward are further provided at the end edges of both sides of the fixing block 6 corresponding to the side in contact with the bow hair 1. The gasket 7 is an elastic structure made of flexible silicone material. The length of the gasket 7 is not greater than the thickness of the fixing block 6. The width of the fixing block 6 is only slightly smaller than the inner diameter of the semi-circular ring plate 52 at the end of the tailstock of the violin bow. In a preferred solution, the gasket 7 is parallel to the surface of the fixing block 6 in the normal state, making it perpendicular to the side surface of the connected fixing block 6. The middle part of the gasket 7 protrudes slightly toward the side in contact with the bow hair 1, making the outer end thereof inclined toward the side of the fixing block 6 away from the bow hair 1. When one end of the gasket 7 follows the contraction section 62 into the end of the tailstock of the violin bow, the gasket 7 bends toward the direction close to the side surface of the fixing block 6 according to its bending direction and fills the gap between the fixing block 6 and the semi-circular ring plate 52.

[0024] Furthermore, a plurality of anti-slip lines are provided on the surface of the gasket 7 close to the bow hair 1, and the anti-slip lines are arranged perpendicular to the direction where the bow hair 1 is located. This makes it more difficult for the gasket 7 to be displaced due to the pulling of the violin bow after being fixed, enabling it to better fill the gap and prevent the movement of the horsehair.

[0025] As Figure 3 shown, as a preferred solution of this embodiment, a concave limiting groove 63 is further provided on the surface of the fixing block 6 corresponding to the bow hair 1. The depth of the limiting groove 63 corresponds to the thickness of the bow hair 1. The edge of the limiting groove 63 is inclined outward and connected to the two side edges of the surface of the fixing block 6, so that the limiting groove 63 is a trapezoidal groove. Through the limiting groove 63, the horsehair can be better restricted in a certain area, making it less likely to move laterally during playing, and the fixation is more stable, thus obtaining a better playing effect. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
