Description

Technical Field

[0001] The utility model relates to the field of violins, in particular to a violin bow. Background Art

[0002] A violin bow is an essential instrument in violin performance. It is a tool used to pull the strings to produce sound. A violin bow usually consists of a bow stick, bow hair, and a bow handle. In traditional violin bow designs, the bow stick is usually made of materials such as wood or carbon fiber, and the bow hair is composed of horsehair or synthetic fiber materials. The performer controls the force, speed, and angle of the bow to produce different timbre effects, thereby realizing the performance of musical works.

[0003] However, in the production process of violin bows, there are some problems with traditional production techniques. For example, the steps of installing the bow hair are cumbersome. If the bow hair is fixed to the bow stick with screws, a screwdriver is needed to rotate the screw counterclockwise to loosen the bow hair from the bow stick; if the bow hair is fixed with a thin string or other means, it needs to be manually untied; generally, there is a tail adjustment screw in the above two schemes to adjust the tension of the bow hair. Since the bow hair is prone to elongation under the influence of environmental humidity and continuous tension, the tailpiece cannot adjust the tension of the bow hair even when it is moved to the outermost end through the tail adjustment screw, thus affecting the performance stability and timbre effect. Summary of the Utility Model

[0004] The utility model aims to provide a new design of violin bow to solve the problems that traditional violin bows are not easy to replace the bow hair, and due to the bow hair being prone to elongation under the influence of environmental humidity and continuous tension, the tailpiece cannot adjust the tension of the bow hair even when it is moved to the outermost end, affecting the performance stability and timbre effect.

[0005] To solve the above technical problems, the technical solutions are as follows:

[0006] A violin bow includes a modular bow string, and also includes a bow stick and a bow head and a bow tail at both ends of the bow stick. The bow tail is provided with a tailpiece, and the bow head is bent towards the side of the bow stick where the tailpiece is provided.

[0007] The modular bow string includes a forming plug, bow hair, and a clamping plug. One end of the bow hair is embedded in the forming plug, and the other end is clamped by the clamping plug;

[0008] The bow head is provided with a clamping mechanism for clamping the forming plug;

[0009] The bow tail is coaxially provided with a bow tail adjustment mechanism, and the tailpiece is detachably fixed to the bow tail adjustment mechanism and moves back and forth along the direction of the bow stick under the action of the bow tail adjustment mechanism;

[0010] The other end of the modular bowstring is fixed in the tail warehouse, and a secondary adjustment mechanism is arranged in the tail warehouse. The secondary adjustment mechanism includes an adjustment screw parallel to the bow rod and a moving mechanism rotated on the adjustment screw. The clamping plug is detachably fixedly connected to the moving mechanism. By rotating the adjustment screw, the moving mechanism can be moved forward and backward in the tail warehouse along the direction of the bow rod.

[0011] Furthermore, the bow tail adjustment mechanism includes a bow tail adjustment bolt which is arranged at the end of the bow tail and is coaxial with the bow rod. A clearance groove is arranged on one side of the bow tail located at the tail reservoir, and the bow tail adjustment bolt extends into the clearance groove; a fixed threaded hole is arranged at the bottom of the tail reservoir, and an eyelet bolt is arranged in the threaded hole, and the eyelet of the eyelet bolt extends into the clearance groove, and a thread is arranged in the eyelet of the eyelet bolt; the bow tail adjustment bolt is screwed into the eyelet of the eyelet bolt in the clearance groove; by rotating the bow tail adjustment bolt, the eyelet bolt can be moved forward and backward along the direction of the bow rod and drive the tail reservoir to move.

[0012] Furthermore, the moving mechanism is provided with a clamping groove which is open on a side away from the bow head for clamping and holding the plug.

[0013] Furthermore, the tail stock has a movable groove, the adjusting screw is arranged in the movable groove, and the two ends are respectively screwed in the tail stock body, the adjusting screw has an adjusting hole coaxially arranged toward the bow head side, and the tail stock body and the adjusting hole have a through hole coaxially arranged, and the adjusting screw can be rotated through the through hole. The lower part of the moving mechanism is provided with a threaded hole, and the moving mechanism is screwed on the adjusting screw through the threaded hole, and the moving mechanism is restricted by the groove wall of the moving groove and cannot rotate with the adjusting screw as the axis.

[0014] Furthermore, a detachable tail storage cover is arranged above the movable groove.

[0015] Furthermore, a bow hair opening is provided on the upper edge of the tail reservoir facing the bow head, and the bow hair opening plug is provided with a wedge to fix the bow hair.

[0016] Furthermore, an arc surface is formed inside the tail reservoir, extending from the bow hair opening to one end of the moving groove close to the bow hair opening, and the arc surface protrudes toward the inner side of the tail reservoir.

[0017] Compared with the prior art, which has the problems of cumbersome bow hair installation and insufficient precision in adjusting the bow hair tension, the utility model has a modular bow hair design. During the installation process, it is only necessary to insert the formed plug into the clamping mechanism and clamp the clamping plug into the clamping slot of the moving mechanism to achieve installation. The bow hair tension is adjusted by the adjusting screw of the tail warehouse and the bow tail adjusting bolt indirectly adjusts the bow hair tension by adjusting the position of the tail warehouse, thereby achieving two-stage adjustment of the bow hair tension.

Detailed implementation manners

[0023] The following is described in conjunction with the drawings and embodiments:

[0024] As Figure 1 shown, a violin bow includes a modular bowstring, and also includes a bow rod 2 and a bow head 21 and a bow tail 22 located at both ends of the bow rod 2. A tail stock 3 is provided at the bow tail 22, and the bow head 21 is bent toward the side of the bow rod 2 where the tail stock 3 is provided.

[0025] As Figure 3 shown, the modular bowstring includes a forming plug 11, bow hair 1, and a clamping plug 12. One end of the bow hair 1 is embedded in the forming plug 11, and the other end is clamped by the clamping plug 12; the forming plug 11 is an integrally formed plug made of resin casting. During the integral forming process, one end of the bow hair 1 is cast in the plug, and the clamping plug 12 is a metal sheet, and the metal sheet is bent by a special pressing machine to clamp the bow hair 1.

[0026] As Figure 4 shown, the bow head 21 is provided with a clamping mechanism 211 for clamping the forming plug 11; preferably, the clamping mechanism 211 is an inverted T-shaped through groove with one side closed. The cross-section of the forming plug 11 is T-shaped and can be inserted into the inverted T-shaped groove from one side. After insertion, another plug that fits the shape of the groove is inserted into the inverted T-shaped groove to fill the inverted T-shaped groove, so that the forming plug 11 can be firmly fixed in the center of the bow head 21. As Figure 1 shown, the clamping mechanism 211 can also be a blind hole. The longitudinal section of the blind hole is trapezoidal, and the surface where the short side of the trapezoid is located is the opening of the blind hole. The forming plug 11 can be inserted into the clamping mechanism 211 and cannot be pulled out.

[0027] As Figure 2As shown, the bow tail adjustment mechanism includes a bow tail adjustment bolt 23 which is arranged at the end of the bow tail 22 and is coaxial with the bow rod 2. A clearance groove is arranged on one side of the bow tail located at the tail depot, and the bow tail adjustment bolt 23 extends into the clearance groove; a fixed threaded hole 37 is arranged at the bottom of the tail depot 3, and an eyelet bolt 24 is arranged in the threaded hole 37. The eyelet of the eyelet bolt 24 extends into the clearance groove, and a thread is arranged in the eyelet of the eyelet bolt 24; the bow tail adjustment bolt 23 is screwed into the eyelet of the eyelet bolt 24 in the clearance groove; by rotating the bow tail adjustment bolt 23, the eyelet bolt 24 can be moved forward and backward along the direction of the bow rod 2 and drive the tail depot 3 to move, and because a clamping plug 12 is also provided in the moving mechanism 39, the tail depot 3 will be subjected to a pulling force toward the bow head 21, so the tail depot 3 will not be offset after being screwed on the eyelet bolt 24.

[0028] like Figure 2 As shown, the other end of the modular bowstring is fixedly set in the tail warehouse 3, and a secondary adjustment mechanism is set in the tail warehouse 3. The secondary adjustment mechanism includes an adjustment screw 33 parallel to the bow rod 2 and a moving mechanism 39 rotated on the adjustment screw 33. By rotating the adjustment screw 33, the moving mechanism 39 can be moved forward and backward in the tail warehouse 3 along the direction of the bow rod 2. The clamping plug 12 is detachably connected to the moving mechanism 39. Furthermore, the moving mechanism 39 is provided with a slot 36 which is open on the side away from the bow head 21 for clamping the clamping plug 12. The tail warehouse 3 has a movable groove, and the adjusting screw rod 33 is arranged in the movable groove, and the two ends are respectively clamped in the body of the tail warehouse 3. The adjusting screw rod 33 has an adjusting hole 38 coaxially arranged toward the side of the bow head 21, and the body of the tail warehouse 3 has a through hole coaxially arranged with the adjusting hole 38. The adjusting screw rod 33 is rotated through the through hole to make the moving mechanism 39 move forward and backward in the tail warehouse 3 along the direction of the bow rod 2. The adjusting hole 38 can be a hexagonal hole or a cross hole or a slotted hole. In this embodiment, the adjusting hole 38 is a hexagonal hole. Preferably, a detachable tail warehouse cover 31 is arranged above the movable groove. The tail warehouse cover 31 plays the role of closing the movable groove, making the tail warehouse 3 more beautiful and preventing the mechanism in the movable groove from being accidentally touched.

[0029] like Figure 2 As shown, preferably, a threaded hole is provided on the lower half of the moving mechanism 39, and the moving mechanism 39 is screwed onto the adjusting screw 33 through the threaded hole. The moving mechanism 39 is restricted by the groove wall of the moving groove and cannot rotate around the adjusting screw 33 as the axis. Therefore, when the adjusting screw 33 rotates, the moving mechanism 39 can move along the groove in the moving groove.

[0030] like Figure 2As shown, further, an upper edge of the tailstock 3 facing the bow head 21 is provided with a hair bow opening 34, and a wedge block 35 is inserted into the hair bow opening 34 to fix the hair bow 1. The wedge block 35 can play a role in fixing the hair bow 1 and reducing the gap between the hair bow 1 and the hair bow opening 34. Further, an arc surface 32 extending from the hair bow opening 34 to one end of the moving groove close to the bow head 21 is formed inside the tailstock 3. The arc surface 32 protrudes towards the inner side of the tailstock 3. The arc surface 32 protruding towards the inner side can prevent the hair bow 1 from being excessively worn when tightened.

[0031] As Figure 1 with Figure 2 shown, before installing the modular bowstring, confirm that the tailstock 3 has been screwed onto the hole bolt 24 of the bow tail 22. After confirmation, the installation can begin. The bowstring of the violin bow is a modular bowstring. One end of the hair bow 1 is embedded in the forming plug 11 of the bow head 21, and the other end is clamped by the clamping plug 12. In actual installation of the modular bowstring, only the forming plug 11 needs to be directly inserted into the clamping mechanism 211. After being fixed, then insert the clamping plug 12 into the clamping groove 36 above the moving mechanism 39. After covering the tailstock cover 31, the tension of the hair bow 1 can be adjusted by rotating the adjusting screw rod 33 through the adjusting hole 38. With a suitable tool, the tension of the hair bow 1 can be adjusted. It can not only be adjusted through the adjusting hole 38 on the tailstock 3, but also the position of the tailstock 3 can be directly adjusted by the bow tail adjusting bolt 23, so as to also achieve the effect of adjusting the tension of the hair bow 1. The two cooperate to realize the two-stage adjustment of the tension of the hair bow 1.
