[0002] For example, a Chinese patent document discloses a saxophone with a novel sound production mechanism [201220229208.7], which includes a sound production mechanism, a tuning pipe, a curved pipe, a bell, and a key system. The sound production mechanism consists of a mouthpiece, a mouthpiece with sound holes, and a key frame. The mouthpiece is installed on the mouthpiece, and the key frame is sleeved on the mouthpiece. The sound production mechanism, the tuning pipe, the curved pipe, and the bell are connected in sequence. The key system is composed of a plurality of sound hole covers and their keys, and the key system is installed on the tuning pipe. The key frame is composed of a frame body, keys made on the frame body, and mounting pieces. The frame body is a ring frame that is separated from the key part on both sides of the mouthpiece and closed at the lower end of the mouthpiece. The mounting pieces are made in the middle position between the ring frames on both sides of the mouthpiece, and the mounting pieces are hinged to the mouthpiece.

[0003] The defect of the above technical solution is that the outer wall of the edge of the sound hole of the mouthpiece is arc-shaped, the tightness of the key cover is poor, and moreover, the long-term deformation of the soft pad of the key cover is large, and it is easy to fail, resulting in a short service life. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Embodiment 1

[0024] Please refer to Figures 1 to 3 , which is a schematic diagram of a tone hole key component of a saxophone blowing tube provided by the present utility model. The saxophone blowing tube tone hole key component includes: a blowing tube 10, a hole-pulling seat 20 and an arc-shaped block 22 arranged on the outer side of the blowing tube 10, and a key cover 30 rotatably arranged on the outer side of the blowing tube 10. It can be imagined that the saxophone blowing tube tone hole key component also includes other functional components and specific structures, such as welding structures, installation structures, etc., which are all well-known technologies to those skilled in the art, so they will not be elaborated in detail here one by one.

[0025] The blowing tube 10 includes a thin straight section 11 and a wide straight section 12, and an arc-shaped section 13 connecting the thin straight section 11 and the wide straight section 12. In this embodiment, the thin straight section 11 and the arc-shaped section 13 are of an integral structure, and the arc-shaped section 13 is sleeved with the wide straight section 12 and then welded. The outer diameter of the blowing tube 10 gradually decreases from the wide straight section 12 towards the thin straight section 11. The outer wall structure of the blowing tube 10 is smooth and flat. There is a tone hole 23 on the blowing tube 10, that is, a tuning hole. Specifically, the tone hole 23 is arranged on the thin straight section 11. The thin straight section 11 is used to connect the mouthpiece, and the wide straight section 12 is used to connect the main tube.

[0026] On one outer wall side of the thin straight section 11 of the blowing tube 10, there is a hole-pulling seat 20 protruding radially outwards. It can be imagined that the wall of the blowing tube 10 is relatively thin. The hole-pulling seat 20 is formed by pulling out the tube wall radially outwards from the position of the tone hole 23, and then curling and welding, which can thicken the thickness of a section of the hole-pulling seat 20 near the outside, and a flat surface 21 is arranged at the end of the hole-pulling seat 20 far from the blowing tube 10, so that the hole-pulling seat 20 forms a flat connection surface on the arc-shaped outer wall of the blowing tube 10, providing a good structural basis for the subsequent welding tightness of the arc-shaped block 22.

[0027] An arc-shaped block 22 in the shape of an oblate circle is welded on the outer wall of the flat surface 21. The lower end of the arc-shaped block 22 can closely adhere to the flat surface 21. There is also a tone hole 23 on the blowing tube 10 that radially penetrates the hole-pulling seat 20 and the arc-shaped block 22 and communicates with the inside of the blowing tube 10. During welding positioning, the positioning needle can be inserted through the hole-pulling seat 20 and the arc-shaped block 22 to form the positioning of the two, reducing the welding difficulty of the arc-shaped block 22 and ensuring the sound quality stability of the tone hole 23 with the same axis. The circumferential edge of the arc-shaped block 22 protrudes from the circumferential edge of the hole-pulling seat 20. The arc-shaped block 22 increases the external area of the tone hole 23 position of the blowing tube 10, and the oblate shape is more suitable for the flipping and covering of the key cover 30.

[0028] One end of the key cover 30 is rotatably arranged on the outer wall of the blowing tube 10. By rotating the key cover 30, it can rotate and approach the outer wall of the arc-shaped block 22. And on the side of the key cover 30 close to the arc-shaped block 22, there is a soft pad 31 that can be attached to the arc-shaped block 22, so as to achieve the purpose of closing and opening the sound hole 23.

[0029] Specifically, on the outer wall of the arc section 13, there are two key shaft columns 32 arranged at intervals and protruding radially outward. Between the key shaft columns 32, there is a fixed shaft 33 parallel to the tangent of the outer wall of the blowing tube 10. The key shaft columns 32 and the fixed shaft 33 cooperate to form a rotation fulcrum of the key cover 30 on the outer wall of the blowing tube 10. One end of the key cover 30 is provided with a rotating rod 34 arranged axially along the outer wall of the blowing tube 10 and keeping a distance from the outer wall of the blowing tube 10. At the same time, there is a gap between the key cover 30 and the outer wall of the blowing tube 10, having enough rotation space.

[0030] The end of the rotating rod 34 away from the key cover 30 is provided with a button ring 35 sleeved on the outside of the blowing tube 10. The button ring 35 has balanced force, avoiding the deformation and bending of the button on the blowing tube 10 due to lateral force.

[0031] On the outer wall of the thin straight section 11, there is a guiding groove 40 for the rotating rod 34 to rotate and snap into. The guiding groove 40 restricts the rotation direction of the rotating rod 34, ensuring that the key cover 30 can accurately rotate and fit on the arc-shaped block 22. And in the fitting state, the peripheral edge of the soft pad 31 protrudes from the peripheral edge of the arc-shaped block 22. The soft pad 31 realizes the full coverage of the arc-shaped block 22, and the sealing performance is improved by cooperating with the soft seal.

Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
