[0023] Reference Figures 1-3 A multi-way connector in the field of pipe fittings is provided, which includes at least three pagoda-shaped tapered heads 1 and connecting pipes 2. The tapered head 1 has a stepped outer diameter decreasing structure. Each tapered head 1 forms an integrated multi-port structure through a connecting pipe 2. The number of ports in the multi-port structure can be expanded to 4-8. In application, the stepped outer diameter decreasing tapered head 1 facilitates the step-by-step connection of hoses, improving sealing and pull-out resistance. The integrated structure reduces assembly interfaces and significantly reduces the size of the joints to solve the problem of equipment space occupation. The number of ports can be expanded, and the modular design can realize flexible configuration of multiple channels to adapt to different pipeline layout requirements and enhance versatility.

[0024] Reference Figures 1-3 The surface of the tapered head 1 is provided with anti-slip texture 101, and the root of the tapered head 1 is provided with an annular limiting flange 102. In application, the anti-slip texture 101 can increase the friction between the hose and the surface of the tapered head 1 to prevent rotation or axial slippage, while the annular limiting flange 102 can provide a clear installation stop for the hose to ensure consistent fitting depth and avoid leakage or detachment due to improper installation.

[0025] Reference Figures 1-3 The connecting pipe 2 is made of polyetheretherketone engineering plastic, and the wall thickness of the connecting pipe 2 is 1.2-2.5mm. In application, polyetheretherketone material has the characteristics of high strength, corrosion resistance and lightweight. While ensuring the wall thickness (1.2-2.5mm), the weight can be further reduced, supporting the compact design. At the same time, the wall thickness can be reduced by using high rigidity material, directly reducing the overall size of the joint and optimizing the space utilization.

[0026] Reference Figure 2 and Figure 3The outer surface of the connecting pipe 2 has four integrally formed reinforcing ribs 201, and the four reinforcing ribs 201 are equidistantly arranged along the axial / circumferential direction of the connecting pipe 2. In application, the axial / circumferential reinforcing ribs 201 can improve the bending and crushing resistance of the connecting pipe 2, make up for the strength shortcomings of the thin-walled design, and at the same time, the equidistant distribution ensures that the stress is evenly distributed and extends the service life of the joint.

[0027] Reference Figure 1 and Figure 2 The connection of the connecting pipe 2 is provided with a transition structure, and a spherical contact part is formed in the intersection area of ​​the axes of the connecting pipe 2. In application, the transition structure and the spherical contact part can optimize the flow direction of the fluid in the intersection area, reduce turbulence and pressure loss, and at the same time, the spherical contact enhances the structural stability of the intersection area and prevents fatigue cracking caused by vibration.

[0028] Reference Figures 1-3 Multi-port structures include configurations of four-way, five-way, six-way, seven-way, or eight-way, with the included angle between the axes of adjacent connecting pipes gradually decreasing. In applications, the design of decreasing included angle allows for compact arrangement of multiple passages within a limited space (such as an eight-way connector), avoiding pipe interference and directly solving the problem of excessive volume. At the same time, the gradual change in included angle conforms to fluid dynamics and can reduce flow resistance.

[0029] Reference Figures 1-3 The integrated structure is formed by precision casting process, and the surface roughness Ra of the integrated structure is ≤3.2μm. In application, the integrated molding can eliminate assembly errors and ensure sealing reliability, while the low surface roughness reduces fluid resistance and improves the machining accuracy of anti-slip texture 101 / annular limiting flange 102, enhancing the anti-detachment effect.
