[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 4As shown, the spiral corrugated pipe with enhanced connection sealing provided by the present embodiment comprises a spiral corrugated section 1, a socket section 2 and a plug section 3 are respectively arranged at both ends of the spiral corrugated section 1, a first annular groove 4 is arranged on the outer wall of the plug section 3, a sealing ring 5 is arranged in the first annular groove 4, and a cable tie 6 is arranged on the outer wall of the bell section 2. By arranging the first annular groove 4 with the sealing ring 5 on the plug section 3 and fixing the socket section 2 with the cable tie 6, a multi-level sealing mechanism is realized to effectively prevent fluid leakage, and the use of stainless steel cable ties has a better effect.

[0025] In this embodiment, if Figure 1 As shown, two circles of first annular grooves 4 are provided, and the two circles of first annular grooves 4 are on the outer side wall of the socket section 3 and are spaced apart along its axial direction, providing double sealing protection. Even if one sealing ring 5 fails, the other one can still maintain sealing, thereby improving reliability.

[0026] In this embodiment, if Figure 1 As shown, the cross-section of the first annular groove 4 is arc-shaped, and the sealing ring 5 protrudes out of the first annular groove 4. When the socket section 2 and the plug section 3 are docked, the protruding sealing ring 5 can more effectively fill the tiny gap between the socket section 2 and the plug section 3 to form a tighter seal, thereby improving the overall sealing effect.

[0027] In this embodiment, if Figure 1 As shown, the bell section 2 is a trumpet-shaped structure, and the inner diameter of the bell section 2 is equal to the outer diameter of the spigot section 3, ensuring that precise matching can be achieved when the pipes are connected.

[0028] In this embodiment, if Figure 2 As shown, a second annular groove 7 is provided on the outer side wall of the socket section 2, and the cable tie 6 is arranged in the second annular groove 7 to provide positioning for the cable tie 6, thereby ensuring that the cable tie 6 applies pressure correctly and evenly and enhancing the connection stability.

[0029] In this embodiment, if Figure 1 As shown, the socket section 2 is provided with a notch 8, and two notches 8 are provided. The two notches 8 are on the socket section 2 and are evenly distributed along its circumference. The socket section 2 can be appropriately tightened when the cable tie 6 is tightened, thereby avoiding local material accumulation or wrinkles caused by tightening, and improving the connection strength and sealing effect.

[0030] In this embodiment, if Figure 1 As shown, a reinforcing rib 9 is provided at the connection between the socket section 2 and the spiral corrugated section 1. There are four reinforcing ribs 9, and the four reinforcing ribs 9 are evenly distributed along the circumference of the socket section 2, so as to enhance the structural strength of the connection between the socket section 2 and the spiral corrugated section 1, prevent deformation, and extend the life of the pipeline.

[0031] In summary, in this embodiment, the spiral corrugated pipe provided in this embodiment is provided with a first annular groove 4 and a sealing ring 5 on the outer side wall of the socket section 3. When the socket section 2 and the socket section 3 are connected, the sealing ring 5 will be compressed with pressure to fill any tiny gaps, thereby providing an effective barrier layer to prevent fluid from leaking through these gaps. After the connection is completed, tighten the cable tie 6 and apply pressure to make the socket section 2 tightly wrapped around the socket section 3, while ensuring the stability of the connection, further compress the sealing ring 5 to enhance its sealing effect.

[0032] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
