[0002] A female pipe adapter is a fitting used to connect two pipes with different internal thread sizes. It is usually made of metal or plastic and has two ports, one with a smaller internal thread and the other with a larger internal thread. This fitting can be used to connect pipes of different sizes to achieve better flow control and water flow direction control in the plumbing system. It is commonly used in home and commercial plumbing systems, such as in bathrooms, kitchens, and laundries.
[0003] The existing internal threaded water pipe conversion joint is usually made of metal when in use. If the joint surface is not treated with anti-corrosion, it is easy to be corroded by water and rust.

When the limit cylinder 3 moves to a point where it cannot move, the threaded downward pressing rod 11 is driven to rotate by rotating the twist 2. During the rotation, the upper wall 8 is continuously pressed downward to limit the movement. After it cannot be pressed downward due to the restriction of the telescopic rod 10, the block 9 is just embedded in the embedding rod 7 for locking, thereby fixing the installation joint 5.
