[0017] This utility model proposes a tee connector for plumbing pipes, including a tee fitting 1, wherein the ends of the three branch pipes 2 of the tee fitting 1 are each equipped with a quick-connect assembly, such as... Figure 1 and Figure 2 As shown, the quick-connect assembly includes a fixed connecting sleeve 3 and a movable connecting sleeve 4. The fixed connecting sleeve 3 includes an inner sleeve 30 and an outer sleeve 31. The inner sleeve 30 has a first through hole 32 at its center, the diameter of which is the same as the outer diameter of the branch pipe 2. One end of the inner sleeve 30 is fixedly fitted onto the outside of the branch pipe 2 through the first through hole 32. A first tapered bevel 33 is cut into the outer wall of the other end of the inner sleeve 30, and a first connector 34 is formed at the end of the inner sleeve 30. Figure 1 As shown, the inner sleeve 30 is fixedly fitted with an outer sleeve 31. The inner sleeve 30 and the outer sleeve 31 are integrally formed. The outer sleeve 31 is located outside the first conical inclined surface 33. A trapezoidal mating space 35 is formed between the first conical inclined surface 33 and the inner wall of the outer sleeve 31. The inner wall of the outer sleeve 31 is provided with threads. In this application, the branch pipe 2 of the tee fitting 1 is integrally formed with the fixed connecting sleeve 3, that is, the branch pipe 2 is integrally formed with the outer sleeve 31 and the inner sleeve 30.

[0018] like Figure 1 As shown, the movable connecting sleeve 4 is cylindrical, with threads on its outer wall. A second through hole 41, with the same diameter as the first through hole 32, is located at the center of the movable connecting sleeve 4. One end of the second through hole 41 is cut with a second tapered bevel 42, forming a second connector 43 at the end of the movable connecting sleeve 4. A ring plate 40 is fixedly fitted onto the end of the movable connecting sleeve 4 away from the second connector 43, and the ring plate 40 is integrally formed with the movable connecting sleeve 4. The movable connecting sleeve 4 is threadedly connected to the outer sleeve 31, and the second connector 43 of the movable connecting sleeve 4 is inserted into the mating space 35, with the first tapered bevel 33 and the second tapered bevel 42 abutting against each other.
