Description

Technical Field

[0001] This utility model belongs to the technical field of musical instruments, and in particular relates to a saxophone that is easy to disassemble and connect. Background Technology

[0002] A patent entitled "A Saxophone" with application number CN201520459204.1 is disclosed in the existing Chinese patent database. The device includes a mouthpiece and a main tube. The mouthpiece and the air inlet of the main tube are connected by a tubular connector and a tubular sleeve fitted on the connector. The sleeve has stripes, which are both long stripes protruding from the surface of the sleeve and long stripes recessed into the surface of the sleeve. This utility model can make the mouthpiece and the main tube more securely combined, facilitate disassembly while ensuring that no damage occurs during disassembly, and ensure that the airflow can pass smoothly during performance, resulting in an ideal playing effect.

[0003] In the existing technology, the combination of the body tube and the bend tube is not very secure, and it is easy to be damaged during long-term disassembly. Therefore, the present invention aims to provide a saxophone that is easy to disassemble and connect, so that the various parts of the saxophone can be combined more securely, while being easy to disassemble. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable connection structure between the body tube and the bend tube. In order to improve its shortcomings, this utility model provides a saxophone that is easy to detach and connect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A saxophone with easy disassembly and connection includes a neck tube, a body tube, and a bend tube. The free end of the body tube is integrally provided with a socket section, and the free end of the bend tube is integrally provided with a spigot section. The spigot section includes a small-diameter section that inserts into the socket section and a large-diameter section that aligns with the end face of the socket section. A hinge plate is integrally provided on the outer surface of the large-diameter section. A pin is inserted between the two hinge plates. A synchronously rotating limiting plate is sleeved on the pin. A snap-fit ​​groove is provided on the limiting plate located on one side of the socket section. A limiting block is provided on the outer surface of the socket section located at the snap-fit ​​groove. The side of the limiting block facing the pin is wedge-shaped. A sliding buckle is slidably connected to the limiting plate located on one side of the spigot section. A torsion spring is sleeved on the pin.

[0007] As a preferred embodiment, the free end of the limiting plate located on one side of the sliding buckle is provided with an opening, and a stop block is provided on the outer surface of the insertion section inside the opening to restrict the rotation of the limiting plate.

[0008] As a preferred embodiment, the upper surface of the free end of the limiting plate located on one side of the sliding buckle has an integral limiting protrusion to prevent the sliding buckle from sliding out of the limiting plate.

[0009] As a preferred embodiment, the upper surface of the sliding buckle is provided with guide arrows and anti-slip protrusions.

[0010] As a preferred embodiment, a sealing groove is provided on the outer circumferential surface of the small-diameter section of the socket section, and a sealing ring is embedded in the sealing groove to prevent air leakage.

[0011] Compared with the prior art, the beneficial effects of this utility model are: due to the cooperative arrangement of the limiting plate and the limiting block, the disassembly and connection between the body tube socket section and the bent tube spigot section can be completed by controlling the rotation of the limiting plate. The connection is firm and the disassembly method is convenient. This device is practical and suitable for industrial production. Attached Figure Description

[0016] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3As shown, a saxophone that is easy to disassemble and connect includes a neck tube 1, a body tube 2, and a bend tube 3. A socket section 4 is integrally provided at the free end of the body tube 2, and a spigot section 5 is integrally provided at the free end of the bend tube 3. The spigot section 5 includes a small diameter section 501 inserted into the socket section 4 and a large diameter section 502 aligned with the end face of the socket section 4. A hinge plate 6 is integrally provided on the outer surface of the large diameter section 502. A pin 7 is inserted between the two hinge plates 6. A synchronously rotating limiting plate 8 is sleeved on the pin 7. A snap-fit ​​groove 9 is provided on the limiting plate 8 located on one side of the socket section 4. A limiting block 10 is provided on the outer surface of the socket section 4 located at the snap-fit ​​groove 9. The side of the limiting block 10 facing the pin 7 is wedge-shaped. A sliding buckle 11 is slidably connected to the limiting plate 8 located on one side of the spigot section 5. A torsion spring 12 is sleeved on the pin 7. An opening 13 is provided at the free end of the limiting plate 8 located on one side of the sliding buckle 11. A stop 14 is provided on the outer surface of the insertion section 5 inside the opening 13 to restrict the rotation of the limiting plate 8. The stop 14 can effectively prevent accidental contact with the sliding buckle 11 and prevent the limiting plate 8 from rotating, causing the body tube 2 to fall off from the bend tube 3 and damaging the bend tube 3. A limiting protrusion 15 is integrally formed on the upper surface of the free end of the limiting plate 8 located on one side of the sliding buckle 11 to prevent the sliding buckle 11 from sliding out of the limiting plate 8. A guide arrow 16 and an anti-slip protrusion 17 are provided on the upper surface of the sliding buckle 11. A sealing groove 18 is provided on the outer circumference of the small diameter section 501 of the insertion section 5, and a sealing ring 19 to prevent air leakage is embedded in the sealing groove 18.

[0018] When it is necessary to connect the body tube 2 and the bend tube 3, the user aligns the spigot section 5 of the bend tube 3 with the socket section 4 of the body tube 2, and inserts the small diameter section 501 into the socket section 4. During the insertion process, the free end of the limiting plate 8 contacts the wedge-shaped surface of the limiting block 10. Due to the action of the wedge-shaped surface, the limiting plate 8 swings clockwise until the locking groove 9 on the limiting plate 8 moves to the limiting block 10. Through the reset action of the torsion spring 12, the limiting plate 8 swings counterclockwise. When reset, the limiting block 10 is engaged in the locking groove 9, and the end face of the large diameter section 502 also abuts against the end face of the socket section 4. When it is necessary to disassemble the body tube 2 and the bend tube 3, push the sliding buckle 11 inward until the lower end of the sliding buckle 11 is disengaged from the stop block 14. Press the sliding buckle 11 down to make the limiting plate 8 swing clockwise, so that the limiting block 10 disengages from the locking groove 9 of the limiting plate 8, thereby disassembling the bend tube 3 and the body tube 2.

[0019] In addition, to make it easier to set features such as the limit block 10, hinge plate 6 and stop block 14, a horizontal plane can be machined on the outer surface of the socket section 4 and the outer surface of the large diameter section 502, and side plates can be set on both sides of the horizontal plane. The entire disassembly structure is set inside the side plates to avoid protruding outside the overall structure. This makes the overall structure set on the horizontal plane rather than the circumferential surface, reducing the difficulty of setting.

[0020] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
