Between.
Preferably, the periphery wall of the embedded ring portion is equipped with annular groove.
Preferably, the radial section of the ending tendon transfer is in U shape structure.
The utility model also provides a kind of water pipe head, including plastic casing and above-mentioned metal insert, the metal insert
It is embedded in the interface end of plastic casing.
Preferably, the rectangular elbow structure of the plastic casing, T-shaped three-port structure or bypass structure.
The beneficial effects of the utility model：Due to being connected with cap bag at the top of insert bodies, cap bag is with respect to insert bodies footpath
Expand face area of the metal insert at plastic casing interface end to protrusion, the plastics that can reduce interface end end face are exposed
Area, delays the aging of interface end；Space is molded due to being left between cap bag and insert bodies again, on insert bodies periphery wall
Equipped with sealing annular groove so that the bonding strength higher between metal insert and plastic casing, holds together, can effectively solve
Certainly due to hot and cold water expands with heat and contract with cold in and delamination between cap bag and plastic casing caused by producing leakage is peeled off and cracking
Phenomenon, sealing and anti-leakage water effect is good, has preferable safety and reliability；Again since cap bag is equipped with reinforcing ring and rotation stop
Muscle, insert bodies periphery wall are equipped with rotation stop column, by ending tendon transfer and rotation stop column cap bag and insert bodies respectively with plastics
It will not relatively rotate between housing, further enhance the connectivity robustness between metal insert and plastic casing and sealing is prevented
Leak performance.
