[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A quick connector for air conditioning water supply pipe, comprising a pipe end one: a rotating ring is rotatably connected to the surface of the pipe end one, a ring block is welded to the surface of the rotating ring, a collar is fixedly connected to the right side of the ring block, a coil spring is fixedly connected between the inner wall of the ring block and the pipe end one, a pipe end two is provided at the right end of the pipe end one, a fixing ring is integrally formed on the surface of the pipe end two, a hook rod one is fixedly connected to the surface of the fixing ring, a hook rod two is fixedly connected to the surface of the collar, a sealing ring one is affixed to the right end of the pipe end one, an insertion ring is fixedly connected to the left end of the pipe end two, an insertion ring groove is opened at the right end of the pipe end one, and wedge-shaped surfaces are opened at the ends of both the hook rod one and the hook rod two.

[0006] Preferably, an annular groove is formed on the surface of the pipeline end, and a limiting ring is rotatably connected to the inner wall of the annular groove, and the rotating ring and the limiting ring are fixedly connected.

[0007] Preferably, the left side of the insert ring extends into the inner cavity of the insert ring groove.

[0008] Preferably, a second sealing ring is adhered to the inner wall of the insertion ring groove.

[0009] Preferably, the end of hook rod one is connected to the end of hook rod two.

[0010] The beneficial effects of this utility model are:

[0011] This invention utilizes a rotating ring block to deform a coil spring, which then connects pipe end one to pipe end two, allowing the insert ring to be inserted into the inner cavity of the insert ring groove. The ring block is then released, causing the spring's rebound force to rotate the collar, which in turn drives hook rod two to engage with hook rod one. Furthermore, the sealing ring ensures a tight seal between pipe end one and pipe end two. This achieves the goal of using the spring's rebound force to engage the L-shaped hook rod, thereby improving the efficiency of pipe connection. Additionally, the slot at the pipe port further enhances the sealing performance of the pipe connection.

[0012] 2. This utility model uses the combination of annular groove and limiting rotating ring to limit the rotation of the rotating ring on one surface of the pipeline end, thereby preventing the rotating ring from shaking during rotation and improving the stability of the rotating ring during rotation.

This achieves the goal of improving the efficiency of pipe connection by using the rebound force of the coil spring to engage the L-shaped hook rod. At the same time, the slot on the pipe port further improves the sealing of the pipe connection.
