Description

Technical Field

[0001] The present invention relates to the technical field of violin shoulder rests, and particularly to a shoulder rest for a violin. Background Art

[0002] In the early days, violin players held the violin against their chests. However, with the improvement of playing skills, the requirements for the left hand have increased day by day, and the traditional playing method can no longer meet the needs. Therefore, the shoulder rest came into being. It can help players better use their left hands, while reducing the burden on the left shoulder, enabling the player to be in a relatively relaxed state, which is beneficial to accurate pronunciation and long-term playing. The use of the shoulder rest also avoids mistakes caused by unstable violin holding, improving the stability and effect of playing.

[0003] After retrieval, the patent with the Chinese patent number CN118968950A discloses a shoulder rest for a violin, including a chin rest component which is installed in the form of being placed on the upper plate of the violin, and a pair of first coupling screw rods are formed on one side; a turnbuckle which is respectively screwed and coupled to the first coupling screw rods; a mounting track on which a pair of second coupling screw rods are respectively coupled on the opposite side of the turnbuckle, and the ends of the second coupling screw rods are constituted by a single path to connect the second coupling screw rods to each other; a clamp which is installed along the path of the mounting track at a position desired by the player; a composite support component which is coupled to the clamp to support the player's shoulder and chest. Compared with the prior art, the patent with the Chinese patent number CN118968950A solves the problems that in the prior art, since the structure of the bracket is that the chin rest and the shoulder rest are independently fixed to the structure of the violin, there are problems of cumbersome and difficult disassembly, and due to the basic installation height of the fixing member for fixing to the violin, for players with shorter necks, there will be problems such as the need to lift the chin and other postures, and problems of chin and neck pain will be caused.

[0004] However, in the actual use process of the above device, the structure of the shoulder rest pad is mostly fixed. However, there are certain differences in the thickness of the shoulders of different users, which makes it difficult for the structurally fixed shoulder rest pad to effectively fit different users, resulting in poor comfort when using the device. Therefore, a shoulder rest for a violin is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages in the prior art that the structure of the shoulder rest pad is mostly fixed, but there are certain differences in the thickness of the shoulders of different users, which makes it difficult for the structurally fixed shoulder rest pad to effectively fit different users, resulting in poor comfort when using the device, and to propose a shoulder rest for a violin.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The third gear 23 is meshed with a transmission rack 20. The side of the transmission rack 20 away from the adjustment housing 7 is rotatably connected to the shoulder support plate 2. When in use, start the second motor 19 to drive the third gear 23 to rotate. The rotation of the third gear 23 drives the engaged transmission rack 20 to move. The movement of the transmission rack 20 drives the shoulder support plate 2 to rotate to adjust the inclination angle of the shoulder support plate 2.

[0032] The fine-tuning mechanism includes a fine-tuning housing 6 provided at the lower part of the adjustment housing 7. Inside the fine-tuning housing 6, a first motor 14 is provided. At the output end of the first motor 14, a first gear 16 is provided. The first gear 16 is meshed and connected with a second gear 17. At the upper part of the second gear 17, a threaded groove 18 is fixedly connected. The upper part of the threaded groove 18 is threadedly connected with a lead screw 10. At the upper part of the lead screw 10, a fine-tuning plate 12 is fixedly connected. Starting the first motor 14 drives the threaded groove 18 to rotate. The rotation of the threaded groove 18 drives the lead screw 10 to move. The movement of the lead screw 10 drives the fine-tuning plate 12 to move, thus fine-tuning the height of the device.

[0033] Inside the adjustment housing 7, a transmission groove 24 is provided. Inside the transmission groove 24, a transmission rack 20 is slidably connected.
