[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, an impact-resistant spiral corrugated pipe includes a pipe body 1, two ends of the pipe body 1 are fixed with connecting ends 2, the interior of the pipe body 1 is provided with an impact-resistant component, the impact-resistant component includes reinforcing ribs 3 arranged at equal angles inside the pipe body 1, rubber blocks 5 are fixed at equal distances on the inner surface of the reinforcing ribs 3, the surface of the rubber blocks 5 is bonded and connected to the inner wall of the pipe body 1, and fixing strips 4 are fixed at equal angles on the inner wall of the connecting end 2, the end of the reinforcing rib 3 passes through the interior of the fixing strip 4, and the outer surface of the end of the reinforcing rib 3 is connected to the inner surface of the fixing strip 4 It fits tightly, and limiting protrusions 6 are equidistantly arranged on the inner surface of the fixing strip 4, and limiting slots 7 are equidistantly arranged on the outer surface of the end of the reinforcing rib 3. The limiting protrusions 6 are snap-connected with the limiting slots 7, and the cross-section of the limiting protrusions 6 is triangular. The limiting protrusions 6 inside the fixing strips 4 inside the two connecting ends 2 are relatively arranged, which is convenient for improving the strength and impact resistance of the spiral bellows during use, so that the spiral bellows is not easily deformed and damaged when subjected to external impact, which can extend the service life of the spiral bellows and has good practicality.

[0021] like Figure 2 and Figure 4 As shown, a sealing assembly is provided on the outer side of the connection end 2, and the sealing assembly includes a sealing ring 8 installed at equal distances on the outer surface of the connection end 2, and a metal spring 9 is fixed at equal angles on the inner surface of the sealing ring 8, and a fixing groove 10 is opened on the outer surface of the connection end 2, and the end of the metal spring 9 is located inside the fixing groove 10, and connecting strips 11 are fixed symmetrically and equidistantly on both sides of the opening of the fixing groove 10, and one end of the connecting strip 11 is fixedly connected to the side bottom surface of the metal spring 9, and the longitudinal section of the metal spring 9 is an inverted "V" shape, and the two end surfaces of the metal spring 9 are fitted and connected to the inner bottom surface of the fixing groove 10, so as to improve the sealing performance of the spiral bellows when it is installed and connected with other pipes, so that the spiral bellows is not prone to leakage when draining water and sewage, and the practical effect is better.

[0022] The utility model provides an impact-resistant spiral corrugated tube, and the specific working principle is as follows: when the utility model installs the impact-resistant component in the early stage, the reinforcing rib 3 is first penetrated through the interior of the tube body 1, so that the rubber block 5 on the inner surface of the reinforcing rib 3 is tightly fitted with the inner wall of the tube body 1, and then the surface of the reinforcing rib 3 is pressed so that the surface of the rubber block 5 is bonded and connected with the inner wall of the tube body 1, so that the reinforcing rib 3 can be limited in the interior of the tube body 1, and then the two ends of the reinforcing rib 3 are penetrated through the interior of the fixing strip 4 on the inner wall of the connecting end 2.
