The first embodiment is as follows: a quick connector for corrugated pipes comprises a connecting sleeve 1, a D-shaped ring 2, a spring clamp 3, a sealing ring 4 and a retainer ring 6, wherein the connecting sleeve 1 comprises a fixing part 11 and a connecting part 12.

Fixed part 11 includes circular opening 15, D type ring 2 sets up in the relative one end of opening, the 11 lateral part of fixed part is equipped with inlays mouthful 16, it is equipped with embedding portion 17 to inlay mouthful 16 both sides, embedding portion 17 includes last depressed part 171 and lower depressed part 172, go up the transition through arcwall face 173 between depressed part and the lower depressed part, spring clamp 3 is the framework that three side formed, the side that lies in both ends can take place to deform at the exogenic action, thereby make first side and second side can be along last depressed part, the arcwall face, lower depressed part motion, realize the installation and the dismantlement of spring clamp. The first side surface 31 and the second side surface 32 are matched with the embedding part 17 in structure, and the blocking part 33 of the first side surface 31 and the blocking part 34 of the second side surface 32 can be positioned with the concave part 171 and the lower concave part 172. The side of the spring clip 3 adjacent the D-ring is open less than the D-ring, thereby confining the D-ring to the end of the retainer portion 11. Some specially configured pipes or components can be secured to the fixture 11 by the spring clip 3 so that liquid or gas within the pipe or component can flow into or out of the fixture. It can be understood that the fixing portion of the present invention is not limited to the structure of the embodiment, and it is within the scope of the present application as long as it can be connected to the opposite end of the bellows and can effectively ensure the liquid or gas to flow through. This section is not described in detail since it is not the focus of the present application. The structure of the fixing part 11 can also refer to the published patent CN 2005800090524.

Connecting portion 12 is for taking the open-ended tubbiness, and sealing ring 4 is the ring shape, and the diameter of sealing ring and the internal diameter phase-match of connecting portion 12, the tip of connecting portion 12 are equipped with draw-in groove 5, and sealing ring 4 sets up in draw-in groove 5 of connecting portion 12 tip to realize the sealing connection of screwed pipe 10. Connecting portion 12's inner wall is equipped with sunken constant head tank 7, constant head tank 7 cross-section is the V-arrangement and sets up along connecting portion inner wall circumference, retaining ring 6 is equipped with the convex part 61 that matches with the constant head tank, through the matching of constant head tank 7 with convex part 61, make retaining ring 6 for connecting portion 12 axial fixity, the tip of retaining ring 6 stretches into in connecting portion 12, and inject sealing ring 4 in draw-in groove 5, the clearance between retaining ring 6 and the connecting portion 12 is less than sealing ring 4's thickness, thereby can prevent effectively that sealing ring 4 from droing at the transportation circulation in-process. One end of the connecting part 12 opposite to the clamping groove 5 is provided with a convex positioning part 14, the retainer ring 6 is provided with a groove 62 matched with the positioning part 14, and the positioning part 14 is arranged in the groove 62. The two positioning parts 14 are symmetrically arranged and matched with the groove 62 through the positioning parts, so that the retainer ring 6 is fixed with the connecting part 12 in the circumferential direction, when the corrugated pipe 10 rotates along the retainer ring 6, the retainer ring 6 can be fixed relative to the connecting part 12, and the retainer ring and the corrugated pipe are prevented from rotating together in the rotation process of the corrugated pipe.

The inner wall of the retainer ring 6 is provided with a thread groove 9, the thread groove 9 is matched with the corrugation on the periphery of the corrugated pipe 10, when the corrugated pipe 10 is rotated, the corrugated pipe can move along the thread groove 9, and the corrugated pipe is fixed through the matching of the thread groove 9 and the corrugation.

The connecting sleeve 1 is provided with a connecting cavity 8, and the connecting cavity 8 extends from one end of the fixing part 11 to one end of the connecting part 12, so that liquid or gas circulation between the fixing part 11 and the connecting part 12 is realized. In the connecting portion 12, the outer periphery of the connecting chamber 8 matches with the inner periphery of the threaded pipe 10, so that when the threaded pipe 10 moves to the outer periphery of the connecting chamber 8, the corrugated pipe 10 can be stably fixed by the outer periphery of the connecting chamber 8 and the spiral groove of the inner periphery of the retainer ring 6 along the outer periphery of the connecting chamber 8.

When a user needs to connect the corrugated pipe 10 with a pipeline to be connected (not shown), the pipeline to be connected is connected with the fixing portion 11 to realize fixing, then the corrugated pipe 10 is placed at one end of the retainer ring 6, then the corrugated pipe 10 is rotated, the corrugated pipe can move along the threaded groove 9, when the end portion of the corrugated pipe 10 reaches the outer periphery of the connecting cavity 8, the inner periphery of the corrugated pipe 10 moves along the outer periphery of the connecting cavity 8, and therefore the connecting strength of the corrugated pipe is improved. And the corrugated pipe is continuously rotated, the end part of the corrugated pipe abuts against the sealing ring 4, and the sealing ring 4 deforms, so that the corrugated pipe 10 and the sealing ring 4 directly form effective sealing. Gas or liquid in the bellows can effectively enter the fixing part 11 via the bellows 10 via the connection chamber 8. Because the sealing ring has been stably fixed in connecting portion 12, consequently need not dispose the sealing ring again when connecting the bellows, also need not other instrument and sealing device, only need rotatory bellows can, consequently can realize the connection equipment of bellows fast, because the sealing ring location sets up, need not think the adjustment, consequently avoids the user because experience problem leads to the sealing ring to set up inaccurate problem, and sealing performance is more reliable. The fixed part is positioned on one side through the spring clamp 3, the operation is simple, and the quick installation is convenient to realize.
