AI Technical Summary
When existing high-ring stiffness double-wall corrugated pipes are bent, the outer corrugated pipe may shift away from the straight pipe, affecting its service life.
The system employs positioning and limiting mechanisms, using structures such as a first retaining ring, a second retaining ring, a first protrusion, and a second protrusion to position and limit the corrugated pipe, ensuring that the corrugated pipe is not easily detached when bent.
It improves the service life of the bellows and the practicality of the device, prevents the bellows from shifting when bending, and enhances connection stability.
