Description

Technical Field

[0001] This utility model belongs to the technical field of musical instruments, and in particular relates to an assembled saxophone with an easy-to-clean neck tube. Background Technology

[0002] A patent titled "A Saxophone Bending Connection Mechanism and a Saxophone" (application number CN202420963083.3) is disclosed in the existing Chinese patent database. This patent addresses the technical problem of unreasonable bending connection designs in existing systems. The saxophone bending connection mechanism includes: a neck tube body in the shape of a bent tube, the outer diameter of which gradually decreases axially; a cylindrical insertion tube fitted onto the wide end of the neck tube body; a circumferentially protruding convex ring on the outer wall of the cylindrical insertion tube near the neck tube body; an arc-shaped concave surface on the side of the convex ring near the neck tube body; and an annular step corresponding to the arc-shaped concave surface on the inner wall of the cylindrical insertion tube. The wide end of the neck tube body is inserted into the cylindrical insertion tube, with its end abutting against the annular step. This saxophone bending connection mechanism reduces the direct impact force between the neck tube body and the cylindrical insertion tube, and by spacing the main stress points from the contact surface, it avoids problems such as changes in tone caused by seal failure after structural deformation.

[0003] In existing saxophones, because the neck tube is closest to the mouthpiece, saliva or impurities can remain inside the neck tube during use, altering the uniformity of airflow and interfering with vibration stability, leading to inaccurate tone. Therefore, this invention aims to propose an assembly-type saxophone that facilitates neck tube cleaning and allows for quick disassembly and reassembly of the neck tube and body tube. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable connection structure between the neck tube and the body tube, so as to facilitate the cleaning of the inside of the neck tube. In order to improve its shortcomings, this utility model provides an assembled saxophone that is easy to clean the neck tube.

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

[0006] An assembled saxophone with an easy-to-clean neck tube includes a neck tube, a body tube, and a bend tube. The free end of the neck tube is integrally provided with a socket section, which includes an external threaded part and a plug part. The free end of the body tube is integrally provided with a plug section. A bushing is screwed onto the external threaded part. An annular boss is integrally provided on the inner surface of the bushing. Several through holes are opened on the outer surface of the plug part opposite to the annular boss. Steel balls are installed in the through holes. An annular groove is opened on the outer circumferential surface of the plug section opposite to the steel balls.

[0007] As a preferred embodiment, a compression spring is fitted onto the insertion part, with one end of the compression spring abutting against the end face of the external threaded part and the other end abutting against the inner end face of the annular boss.

[0008] As a preferred embodiment, when the spigot section is connected to the socket section, the annular boss and the annular groove are aligned, and the outer end face of the bushing is fitted to the free end face of the tube.

[0009] As a preferred embodiment, the edge of the annular groove is set in an open shape.

[0010] As a preferred embodiment, a sealing groove is provided on the outer peripheral surface of the socket section, and a sealing ring is embedded in the sealing groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: due to the matching arrangement of the socket section, the spigot section and the bushing, the disassembly and connection and installation between the neck tube and the body tube can be completed quickly. The structure is firmly connected and the disassembly method is convenient, which makes it easy to quickly disassemble the neck tube from the body tube for cleaning inside the tube. This device is practical and suitable for industrial production. Attached Figure Description

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, this is an assembled saxophone with an easy-to-clean neck tube, comprising a neck tube 1, a body tube 2, and a bend tube 3. A socket section 4 is integrally formed at the free end of the neck tube 1, including an external threaded portion 401 and a plug portion 402. A plug section 5 is integrally formed at the free end of the body tube 2. A bushing 6 is screwed onto the external threaded portion 401. An annular boss 7 is integrally formed on the inner surface of the bushing 6. Several through holes 8 are formed on the outer surface of the plug portion 402 opposite to the annular boss 7, and steel balls 9 are installed in the through holes 8. An annular groove 10 is formed on the outer circumferential surface of the plug section 5 opposite to the steel balls 9. A compression spring 11 is sleeved on the plug portion 402, with one end of the compression spring 11 abutting against the end face of the external threaded portion 401 and the other end abutting against the inner end face of the annular boss 7. The compression spring 11 ensures that when the bushing 6 is rotated to the left, a certain spring force must be overcome, effectively preventing the bushing 6 from being rotated arbitrarily and causing the neck tube 1 to detach from the body tube 2, thus improving safety. When the spigot section 5 is connected to the socket section 4, the annular boss 7 and the annular groove 10 are aligned, and the outer end face of the bushing 6 is fitted against the free end face of the body tube 2. The edge of the annular groove 10 is open. A sealing groove 12 is provided on the outer circumference of the spigot section 5, and a sealing groove 12 is embedded within the sealing groove 12.

[0017] When it is necessary to disassemble the neck tube 1 from the body tube 2, rotate the bushing 6 to the left until the annular boss 7 disengages from the through hole 8. At this time, pull the socket section 4 of the neck tube 1 out from the insertion section 5 of the body tube 2. During the relative movement of the socket section 4 and the insertion section 5, the insertion section 5 squeezes the steel ball 9 to move outward from the through hole 8, thus completing the disassembly of the neck tube 1 from the body tube 2. While the steel ball 9 moves within the through hole 8, it always maintains a certain friction with the inner wall of the through hole 8, thereby preventing the steel ball from detaching when the insertion section 5 disengages from the socket section 4. 9 falls out of the through hole 8. When it is necessary to install the neck tube 1 and the body tube 2, insert the spigot section 5 of the body tube 2 into the socket section 4 of the neck tube 1 until the end face of the socket section 4 abuts against the free end face of the body tube 2. Rotate the bushing 6 to the right until the outer end face of the bushing 6 abuts against the free end face of the body tube 2. During this process, the surface of the annular boss 7 is arc-shaped, squeezing the steel ball 9 to move towards the annular groove 10, thereby limiting the axial movement of the spigot section 5. The assembly of the neck tube 1 and the body tube 2 is thus completed.

[0018] 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.
