Description
Technical Field
[0001] This utility model relates to the field of musical instrument manufacturing technology, and more specifically, to a flexible saxophone key structure with built-in springs. Background Technology
[0002] The saxophone is a brass instrument belonging to the woodwind family, typically made of brass. With its rich and varied tone, it is widely used in classical, jazz, and pop music. Its sound production principle involves the player blowing air into the mouthpiece; the airflow passes through the headstock, causing it to vibrate. By controlling the opening and closing of different tone holes, the length of the vibrating air column is adjusted, thus producing different pitches. The saxophone keys are the core components controlling the opening and closing of the tone holes. They typically consist of the key body, a transmission structure, and a reset element. The player presses or releases the keys, causing the relevant components to move, sealing or opening the tone holes, thereby precisely controlling the pitch of the instrument. The flexibility, stability, and ease of maintenance of the keys directly affect the player's experience and the instrument's lifespan.
[0003] Currently, most saxophones on the market use an external pin spring design for their keys, meaning the spring used to reset the keys is directly exposed outside the keys. This external pin spring structure presents several problems in practical use: 1. The exposed pin spring is easily caught on the player's clothing or surrounding objects, causing the spring to deform or even break, thus affecting the normal reset of the keys. Additionally, dust, lint, and other impurities from the external environment easily adhere to the spring and key connection, increasing cleaning difficulty and potentially causing key jamming due to accumulated impurities, disrupting the smoothness of the pressing and reset process, affecting the precision of the playing feel, and even impacting the overall aesthetics of the instrument; 2. Due to the lack of convenient disassembly design in existing key structures, when springs wear out, sealing rings age, or dust and water accumulate inside the keys requiring maintenance, it is often necessary to disassemble the entire key assembly using specialized tools. The disassembly process is cumbersome and complex, not only consuming a lot of time but also potentially damaging the key components due to improper operation, significantly increasing maintenance costs and time, and causing great inconvenience to the player's daily maintenance.
[0004] Therefore, there is an urgent need for a flexible saxophone key structure with a built-in spring to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a flexible saxophone key structure with a built-in spring to solve the problems mentioned in the background art.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A flexible saxophone key structure with a built-in spring, including a tone hole seat, and further comprising: A sealing groove is formed on the side wall of the tone hole seat, and the tone hole seat is installed on the saxophone through the sealing groove; A circular ring is slidably connected to the tone hole seat through a circular groove formed on the inner wall of the tone hole seat, and a uniformly distributed guide block is fixedly connected to the bottom of the circular ring. Support columns are evenly and fixedly connected to the top of the circular ring, and a button body is fixedly connected to the top of the support columns. The top of the button body is provided with anti-slip texture. A sealing ring is fixedly connected to the side wall of the key body, and the sealing ring cooperates with the tone hole seat; Built-in spring assembly, including: The slider is slidably connected to the tone hole seat through grooves evenly distributed on the inner wall of the tone hole seat; A strong spring B is fixedly connected at one end to the slider and at the other end to the inner wall of the groove. A receiving hole is formed in the side wall of the slider; A quick-release assembly is disposed on the inner wall of the receiving hole, and the quick-release assembly cooperates with the built-in spring assembly.
[0007] As a preferred technical solution of this application, the quick-disassembly assembly includes: A connecting block is slidably connected to the inner wall of the receiving hole, and the connecting block is slidably connected to the guide block through a connecting groove formed on the side wall of the guide block; A strong spring A is fixedly connected at one end to the connecting block and at the other end to the inner wall of the connecting groove.
[0008] As a preferred technical solution of this application, the bottom of the guide block is provided with a guide surface A, and the outer wall of the guide surface A cooperates with the top of the connecting block.
[0009] As a preferred technical solution of this application, the inner wall of the connecting groove is provided with a guide surface B, and the outer wall of the guide surface B cooperates with the bottom of the connecting block.
[0010] As a preferred technical solution of this application, the inner wall of the sound hole seat is provided with uniformly distributed guide grooves that are slidably connected to the guide block, and the guide grooves are connected to the circular grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By incorporating a powerful spring B within the groove of the tonehole seat, the problem of traditional external needle springs being easily hooked and deformed is avoided. The concealed design also reduces dust accumulation, making cleaning easier and enhancing the overall aesthetics of the saxophone. Furthermore, the guide groove, in conjunction with the guide block's limiting action, ensures smooth and uninterrupted key pressing and reset, improving the playing feel and precision. This solves the problems of existing technology where external needle springs are easily hooked, deformed, or broken, affecting key reset, and are prone to dust accumulation and difficult cleaning, leading to key jamming, reduced feel, and unsightly appearance. 2. By using the connecting block, strong spring A, receiving hole, and connecting groove of the quick-release component, along with guide surface A and guide surface B, quick disassembly can be achieved by pressing to install and pulling upwards to separate. No special tools are needed to quickly separate the button assembly from the sound hole seat, making it easy to clean dust and water stains inside the button, or replace worn springs, sealing rings, and other parts, reducing maintenance costs and time costs. This solves the problem of existing technologies where buttons lack convenient disassembly design, maintenance requires tools for disassembly, and involves time-consuming, cumbersome, and easily damaged parts.

Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0015] like Figure 1-5 As shown, this embodiment proposes a flexible saxophone key structure with a built-in spring, including a tone hole seat 1, and further comprising: The sealing groove 2 is opened on the side wall of the tone hole seat 1, and the tone hole seat 1 is installed on the saxophone through the sealing groove 2; The circular ring 5 is slidably connected to the tone hole seat 1 through the circular groove 3 opened on the inner wall of the tone hole seat 1, and the bottom of the circular ring 5 is fixedly connected with evenly distributed guide blocks 6. Support column 8 is evenly and fixedly connected to the top of circular ring 5, and button body 9 is fixedly connected to the top of support column 8. Anti-slip texture 13 is provided on the top of button body 9. The sealing ring 10 is fixedly connected to the side wall of the key body 9, and the sealing ring 10 cooperates with the tone hole seat 1. Built-in spring assembly, including: The slider 15 is slidably connected to the tone hole seat 1 through the sliding grooves 19 evenly opened on the inner wall of the tone hole seat 1; A strong spring B18 is fixedly connected at one end to the slider 15 and at the other end to the inner wall of the slide groove 19. The receiving hole 16 is located on the side wall of the slider 15. When the player presses the key body 9, the key body 9 drives the circular ring 5 to slide down along the circular groove 3 via the support column 8. The circular ring 5 drives the guide block 6 to move down along the guide groove 4. During the movement of the guide block 6, since the top of the connecting block 14 and the top of the inner wall of the connecting groove 11 are the same horizontal surface, the connecting groove 11 squeezes and pushes the connecting block 14 to move, which in turn pushes the slider 15 to slide down along the slide groove 19 again and compresses the strong spring B18. At the same time, the sealing ring 10 moves down with the key body 9 and cooperates with the tone hole seat 1 to seal the tone hole, changing the airflow channel inside the saxophone, thereby producing the corresponding tone. After the player releases the key body 9, the compressed strong spring B18 releases its elasticity, pushing the slider 15 to reset. The slider 15 drives the guide block 6 to move up via the connecting block 14. The guide block 6 drives the circular ring 5 and the support column 8 to move up simultaneously, finally restoring the key body 9 to its initial position. The sealing state between the sealing ring 10 and the tone hole seat 1 is released, preparing for the next key press. A quick-release assembly is located on the inner wall of the receiving hole 16, and the quick-release assembly cooperates with the built-in spring assembly.
[0016] like Figure 3-5 As shown, in a preferred embodiment, based on the above method, a further method for quick disassembly of the components includes: The connecting block 14 is slidably connected to the inner wall of the receiving hole 16, and the connecting block 14 is slidably connected to the guide block 6 through the connecting groove 11 opened on the side wall of the guide block 6; A strong spring A17 is fixedly connected at one end to the connecting block 14 and at the other end to the inner wall of the connecting groove 11. During assembly, the circular ring 5 with the guide block 6 is aligned with the circular groove 3 and the guide groove 4 on the inner wall of the tone hole seat 1. Since the bottom of the guide block 6 has a guide surface A7, when the circular ring 5 is pressed, the guide surface A7 will contact the top of the guide block 6 and generate pressure, pushing the connecting block 14 to slide away from the guide block 6 along the receiving hole 16, while compressing the strong spring A17. When the connecting groove 11 on the guide block 6 is aligned with the receiving hole 16 on the side wall of the slider 15, the compressed strong spring A17 releases its elastic force, pushing the connecting block 14 to reset, so that the connecting block 14 is embedded in the connecting groove 11 under the action of the strong spring A17, completing the connection between the circular ring 5 and the tone hole seat 1, that is, realizing the assembly of the button body 9 and the tone hole seat 1.
[0017] like Figure 4 As shown, in a preferred embodiment, based on the above method, the bottom of the guide block 6 is further provided with a guide surface A7, and the outer wall of the guide surface A7 cooperates with the top of the connecting block 14. The guide surface A7 will contact the top of the guide block 6 and generate pressure, pushing the connecting block 14 to slide away from the guide block 6 along the receiving hole 16, while compressing the strong spring A17.
[0018] like Figure 4 As shown, in a preferred embodiment, based on the above method, the inner wall of the connecting groove 11 is further provided with a guide surface B12, and the outer wall of the guide surface B12 cooperates with the bottom of the connecting block 14. When maintenance or replacement of parts is required, the button body 9 is pulled upwards. The button body 9 drives the guide block 6 to move upwards through the support column 8 and the circular ring 5. Since the inner wall of the connecting groove 11 has a guide surface B12, the guide surface B12 will contact the bottom of the connecting block 14 and generate pressure, pushing the connecting block 14 to compress the strong spring A17 and retract into the receiving hole 16. After the connecting block 14 is completely separated from the connecting groove 11, the button body 9 is pulled upwards again, and the circular ring 5, support column 8, button body 9 and other button components can be taken out from the circular groove 3 and guide groove 4 of the sound hole seat 1. Then, the internal dust and water stains can be cleaned.
[0019] like Figure 2 As shown, in a preferred embodiment, based on the above method, the inner wall of the sound hole seat 1 is further provided with a guide groove 4 that is evenly distributed and slidably connected to the guide block 6. The guide groove 4 is connected to the circular groove 3. The guide groove 4 ensures that the guide block 6 is in the correct position, and at the same time ensures that the connecting groove 11 and the connecting block 14 are successfully connected and installed.
[0020] Specifically, in use, the flexible saxophone key structure with built-in springs works as follows: First, the entire tone hole seat 1 is installed and fixed onto the saxophone via the sealing groove 2 on the side wall of the tone hole seat 1, providing basic support for the subsequent assembly and operation of the key components; during assembly, the circular ring 5 with guide block 6 is aligned with the circular groove 3 and guide groove 4 on the inner wall of the tone hole seat 1. Since the bottom of the guide block 6 has a guide surface A7, when the circular ring 5 is pressed, the guide surface A7 will contact the top of the guide block 6 and generate pressure, pushing the connecting block 14 to slide away from the guide block 6 along the receiving hole 16, while compressing the strong spring A17; when the connecting groove 1 on the guide block 6... When the slider 15 is aligned with the receiving hole 16 on its side wall, the compressed and strong spring A17 releases its elastic force, pushing the connecting block 14 back to its original position. Under the action of the strong spring A17, the connecting block 14 is embedded in the connecting groove 11, completing the connection between the circular ring 5 and the tone hole seat 1, thus realizing the assembly of the key body 9 and the tone hole seat 1. When the player presses the key body 9, the key body 9 drives the circular ring 5 to slide down along the circular groove 3 through the support column 8. The circular ring 5 drives the guide block 6 to move down synchronously along the guide groove 4. During the movement of the guide block 6, since the top of the connecting block 14 and the top of the inner wall of the connecting groove 11 are the same horizontal surface, the pressing action is achieved by squeezing and pushing through the connecting groove 11. The moving connecting block 14 moves, which in turn pushes the slider 15 to slide along the slide groove 19 again and compress the strong spring B18. At the same time, the sealing ring 10 moves down with the key body 9 and cooperates with the tone hole seat 1 to seal the tone hole, changing the airflow channel inside the saxophone and thus producing the corresponding tone. After the player releases the key body 9, the compressed strong spring B18 releases its elasticity, pushing the slider 15 to reset. The slider 15 drives the guide block 6 to move upward through the connecting block 14. The guide block 6 drives the circular ring 5 and the support column 8 to move upward simultaneously, finally restoring the key body 9 to its initial position. The sealing state between the sealing ring 10 and the tone hole seat 1 is released, ready for the next press. Prepare the button; when maintenance or replacement of parts is required, pull the button body 9 upwards. The button body 9 moves the guide block 6 upwards through the support column 8 and the circular ring 5. Since there is a guide surface B12 on the inner wall of the connecting groove 11, the guide surface B12 will contact the bottom of the connecting block 14 and generate pressure, pushing the connecting block 14 to compress the strong spring A17 and retract into the receiving hole 16. After the connecting block 14 is completely separated from the connecting groove 11, continue to pull the button body 9 upwards to remove the button components such as the circular ring 5, support column 8, and button body 9 from the circular groove 3 and guide groove 4 of the tone hole seat 1. Then, the internal dust and water stains can be cleaned.
[0021] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
