Description

Technical Field

[0001] This utility model belongs to the technical field of violin tuning, specifically, it relates to an auxiliary device for adjusting violin tuning pegs. Background Technology

[0002] Violin is a general term for a class of stringed instruments, belonging to the erhu family, and can also specifically refer to bowed string instruments such as the violin, viola, cello, and double bass. Before playing, violins usually need to be tuned, often by adjusting the tension of the strings using tuning pegs.

[0003] Traditional violins use wooden tuning pegs, which are fixed to the tuning peg slots by a conical wedge structure. In use, the strings pass through the string hole in the center of the tuning peg and are wound around the cone-shaped part of the peg. To tune, the thumb rest is held at the head of the tuning peg, and the peg is rotated clockwise or counterclockwise to adjust the string tension. After tuning, the peg is pressed inwards to secure it using the conical wedge structure.

[0004] However, wooden tuning pins are prone to swelling in humid environments, causing them to jam in the tuning pin slot. In this case, more force is required to rotate the tuning pin, making it difficult for users with weaker hand strength to operate.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] In order to solve at least some of the above-mentioned problems, this utility model provides an auxiliary device for adjusting violin tuning pegs.

[0007] The basic concept of the technical solution adopted in this utility model is:

[0008] An auxiliary device for adjusting violin tuning pins includes a base and at least one pair of flexible clips. The base has a receiving groove for accommodating the head of the tuning pin. The at least one pair of flexible clips are located on two opposite groove walls of the receiving groove and are in contact with two concave surfaces of the head of the tuning pin.

[0009] Furthermore, the auxiliary device also includes a flexible pad, which covers the walls and bottom of the receiving groove, and a flexible clip is disposed on the flexible pad.

[0010] Furthermore, the auxiliary device also includes a flexible support member, which is located on the side of the flexible pad away from the groove wall.

[0011] Furthermore, there are two flexible support members, which are positioned opposite each other on the two sides of the flexible pad.

[0012] Furthermore, the flexible support has an internal hollow structure, and the substrate has air holes that communicate with the interior of the flexible support.

[0013] Furthermore, the flexible support component and the flexible pad are integrally molded.

[0014] Furthermore, the auxiliary device also includes a connector, one end of which is connected to the side of the base away from the receiving groove.

[0015] Furthermore, the opening of the receiving groove is a flared structure, and the flexible clamp is located at the bend of the receiving groove opening.

[0016] Furthermore, the bottom of the receiving tank is provided with a deep groove.

[0017] Furthermore, the flexible clips are configured in two pairs, and the distribution direction of the two pairs of flexible clips is perpendicular to the direction of the receiving groove toward the depth groove.

[0018] This utility model has at least the following beneficial effects:

[0019] 1. This utility model, by matching the receiving groove of the base body with the geometry of the chord head, and the flexible clamping part conforming to the concave surface through elastic deformation, forms a stable clamping structure with three-point contact. It can effectively solve the problem of uneven force application caused by the slippage of the chord head when turning by hand in the traditional way, and can provide users with a better force application position when the chord is damp and expands, thereby improving the user's ease of operation.

[0020] 2. This utility model uses a flexible clamp to evenly distribute the rotational force applied by the user to the concave surface of the tuning pin head, reducing local stress concentration and reducing the torque required for tuning, thereby significantly alleviating the operational burden on users with insufficient hand strength.

[0021] 3. This utility model uses a flexible clamping component to compensate for fluctuations in the size of the tuning pin caused by changes in temperature and humidity, maintaining clamping stability and thus improving the accuracy of tuning. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 2 As shown, this utility model provides an auxiliary device for adjusting violin tuning pegs. Figure 1 A schematic diagram of the auxiliary device in an embodiment of this utility model is shown. Figure 2 A cross-sectional view of the interior of the base in the auxiliary device is shown.

[0032] According to the example embodiment, such as Figure 1 and Figure 2 As shown, an auxiliary device for adjusting violin tuning pins includes a base 1 and at least one pair of flexible clips 2. The base 1 has a receiving groove 11 for accommodating the head of the tuning pin. The at least one pair of flexible clips 2 are respectively located on two opposite groove walls of the receiving groove 11 and are in contact with two concave surfaces of the head of the tuning pin.

[0033] For example, the substrate 1 can be, but is not limited to, a spherical structure or a block structure. If the substrate 1 is a spherical structure, its diameter can range from 20 to 50 mm. The spherical structure also allows the substrate 1 to rotate in multiple directions, enabling the user to select the most comfortable adjustment angle as needed. If the substrate 1 is a block structure, it can specifically be a cube with a side length ranging from 20 to 50 mm.

[0034] The material selected for the matrix 1 can be, but is not limited to, engineering plastics, composite materials, or metals. Specifically, if the matrix 1 is made of engineering plastics, unsaturated polyester resin and epoxy resin can be used for injection molding, as they have moderate elastic modulus and low cost. If the matrix 1 is made of metals, specifically, aluminum alloy-based composite materials can be used.

[0035] When the matrix 1 is a composite plastic, specifically, a glass fiber reinforced resin matrix composite material can be selected. The glass fiber reinforced resin matrix composite material has both lightweight and high strength properties, and its large elongation can meet the elastic deformation requirements of the flexible card part 2.

[0036] Anti-slip textures or grooves can be provided on the outer surface of the substrate 1 to enhance friction and prevent slippage during adjustment.

[0037] Optionally, the auxiliary device also includes a connector 5, one end of which is connected to the side of the base 1 away from the receiving groove 11.

[0038] For example, connector 5 can be a connecting rod, and the connection between the connecting rod and the base 1 can be an integrally formed structure. Alternatively, the connecting rod can be connected to the base 1 by inserting it into the groove 14 on the protrusion 13.

[0039] Specifically, the protrusion 13 is integrally formed with the base 1, and a groove 14 is formed on the protrusion 13. The groove 14 is adapted to one end of the connecting rod, and the connecting rod can be inserted into the groove 14. More specifically, the connecting rod has a universal hexagonal connecting rod, the groove 14 has a regular hexagonal cross-section, and the end of the connecting rod away from the groove 14 can be held by a universal ratchet screwdriver 6 or a regular wrench to increase the torque and thus increase the assist.

[0040] It should be noted that, taking one embodiment as an example, the Z-axis is the direction parallel to the axial direction of the connecting rod. The X-axis and Y-axis are defined with the Z-axis as the reference. The receiving groove 11 can be through the X-axis, the groove wall is directly opposite the Y-axis, and the direction of the groove opening is on the Z-axis.

[0041] For example, the cross-section of the receiving groove 11 on the ZOY plane is U-shaped, and the width of the receiving groove 11 in the Y-axis direction is slightly larger than the diameter of the chord head to ensure that the chord head can be easily inserted and with adjustment margin. The depth of the receiving groove 11 in the Z-axis direction is slightly larger than the height of the chord head.

[0042] Optionally, the opening of the receiving groove 11 is a flared structure, and a deep groove 12 is formed at the bottom of the receiving groove 11. Specifically, the two groove walls of the receiving groove 11 are folded along an arc-shaped path in a direction away from each other to form a flared structure. The receiving groove 11 is recessed in the direction away from the opening along the Z-axis to form the deep groove 12. The deep groove 12 is closed along the X-axis, that is, the cross-section on the ZOX plane is U-shaped, and the interior of the deep groove 12 has a smooth transition.

[0043] For example, multiple pairs of flexible clips 2 can be provided, distributed along the X-axis on the groove wall, with each pair of flexible clips 2 being centrally symmetrical. During the screwing of the base 1, each pair of flexible clips 2 contacts the two concave surfaces of the chord shaft head.

[0044] Optionally, the flexible clips 2 are configured as two pairs, and the distribution direction of the two pairs of flexible clips 2 is perpendicular to the direction of the receiving groove 11 toward the longitudinal groove 12.

[0045] The flexible clip 2 may be made of materials including, but not limited to, silicone or polydimethylsiloxane. Specifically, the flexible clip 2 may be made of silicone with a Shore hardness of 50A. The flexible clip 2 may be, but not limited to, a hemispherical structure or a thumb-shaped structure. The aforementioned structures enable the flexible clip 2 to have an arc-shaped contact surface that matches the concave shape of the head of the chord shaft.

[0046] For example, such as Figure 1 and Figure 2 As shown, the substrate 1 has a spherical structure with a diameter of 35mm, and is made of aluminum alloy composite material. A protrusion 13 is provided on the outer surface of the substrate 1, integrally formed with the substrate 1, and the outer surface of the protrusion 13 smoothly transitions to the outer surface of the substrate 1. A groove 14 is formed on the end of the protrusion 13 away from the substrate 1, and the cross-section of the groove 14 is a regular hexagon. The connector 5 is a connecting rod, which is a universally sized hexagonal connecting rod. One end of the connecting rod is inserted and fixed into the groove 14, and the other end is connected to a ratchet screwdriver 6.

[0047] With the center of the base 1 as the origin O, the axis of the connecting rod as the Z-axis, and the X-axis and Y-axis defined with the Z-axis as the reference. The receiving groove 11 extends through the X-axis, the groove wall is directly opposite the Y-axis, and the Z-axis points upwards towards the groove opening. The receiving groove 11 is recessed along the Z-axis in a direction away from the groove opening to form a deep groove 12, which is closed along the X-axis.

[0048] The two walls of the receiving groove 11 are folded along an arc-shaped path in a direction away from each other, forming a flared structure. The cross-section of the receiving groove 11 in the ZOY plane is U-shaped, and the cross-section of the deep groove 12 in the ZOX plane is U-shaped. The interior of the deep groove 12 has a smooth transition.

[0049] Two pairs of flexible clips 2 are provided, distributed along the X-axis on the groove wall. Each pair of flexible clips 2 is centrally symmetrical and located at the edge of the groove wall along the X-axis direction, specifically at the bend of the groove opening of the receiving groove 11. The flexible clips 2 are made of silicone material with a Shore hardness of 50A and have a hemispherical structure.

[0050] Through the above embodiments, this utility model uses a ratchet screwdriver 6 to increase the torque and assist in tightening the connecting rod. The connecting rod drives the base 1 to rotate, causing a pair of flexible clips 2 to contact and gradually press the concave surface of the string pin head, driving the string pin head to rotate. This utility model increases the effective contact area through the hemispherical contact surface, which can reduce local pressure, thereby avoiding scratching the string pin surface while maintaining sufficient clamping force to transmit torque, thus improving the user's ease of operation.

[0051] According to the example embodiment, such as Figure 1 and Figure 2 As shown, an auxiliary device for adjusting violin tuning pegs also includes a flexible pad 3, which covers the groove wall and bottom of the receiving groove 11, and a flexible clip 2 is disposed on the flexible pad 3.

[0052] For example, the thickness of the flexible pad 3 can be between 1.5 and 2 mm. The flexible pad 3 can be integrally injection molded from silicone material so that it can closely fit the wall of the receiving groove 11. The flexible pad 3 can extend into the deep groove 12, covering the groove wall and bottom of the deep groove 12. The flexible clip 2 adopts a hemispherical structure and is combined with the flexible pad 3 through a secondary injection molding process.

[0053] For example, such as Figure 2 As shown, the flexible pad 3 has a thickness of 1.5mm. The flexible pad 3 is integrally injection molded from silicone material, extending from the opening of the receiving groove 11 to the depth groove 12, covering the groove wall of the receiving groove 11 as well as the groove wall and bottom of the depth groove 12.

[0054] Through the above embodiments, the present invention tightly covers the interior of the substrate 1 with a flexible pad 3. The damping characteristics of the silicone material can effectively absorb the vibration generated during the adjustment process, while avoiding hard contact between the wooden tuning pin and the metal substrate 1, thereby preventing scratches on the tuning pin and extending the service life of the tuning pin.

[0055] According to the example embodiment, such as Figure 2As shown, an auxiliary device for adjusting violin tuning pegs also includes a flexible support 4, which is disposed on the side of the flexible pad 3 away from the groove wall of the receiving groove 11.

[0056] For example, the flexible support 4 may be, but is not limited to, a hemispherical or semi-elliptical structure, and the material used for the flexible support 4 may be, but is not limited to, silicone or polydimethylsiloxane. The flexible support 4 is disposed on the flexible pad 3, and its position corresponds to the center position of the wall of the receiving groove 11. The flexible support 4 may be bonded to the flexible pad 3, or it may be integrally injection molded with the flexible pad 3.

[0057] Optionally, two flexible support members 4 are provided, with the two flexible support members 4 facing each other on the two sides of the flexible pad 3. The flexible support member 4 has an internal hollow structure, and the substrate 1 has air holes 41 that communicate with the interior of the flexible support member 4. The flexible support member 4 and the flexible pad 3 are integrally formed.

[0058] For example, the diameter of the pore 41 can be between 1.2 and 1.5 mm, and a cutting plane can be provided on the outer surface of the substrate 1, with the pore 41 located on the cutting plane.

[0059] For example, such as Figure 1 and Figure 2 As shown, two flexible support members 4 are provided, which are positioned opposite each other on the two sides of the flexible pad 3, and their positions correspond to the center position of the groove wall of the receiving groove 11. The flexible support members 4 are integrally formed with the flexible pad 3, and the flexible support members 4 are made of silicone material. The flexible support members 4 have a hemispherical structure and a hollow internal structure. The substrate 1 has air holes 41 that communicate with the interior of the flexible support members 4. The diameter of the air holes 41 is 1.2 mm. The outer surface of the substrate 1 has a tangential plane, and the air holes 41 are located on the tangential plane.

[0060] Through the above embodiments, the present invention, through the flexible support 4, when the head of the chord shaft is embedded in the receiving groove 11, the flexible support 4 generates controllable deformation under air pressure, which is uniformly transmitted to the concave surface of the chord shaft through the flexible pad 3, thereby improving the uniformity of the contact pressure distribution. Furthermore, by using silicone material for the flexible support 4, the tensile strength range of the flexible support 4 can ensure the structural stability under air pressure and avoid stress relaxation caused by excessive deformation, thus making it easy to maintain the resilience of the flexible support 4.

[0061] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
