[0002] Anti-leakage water inlet pipe structures are usually used in water tanks, water pipe systems or other liquid storage equipment to prevent water leakage or leakage, ensure the effective use of water resources and the safe operation of equipment;

[0003] Because the water inlet pipe is full of pressure for a long time during actual use, once the pipe breaks, it will cause indoor flooding accidents in the home. In addition, after the water inlet pipe is assembled and connected with the faucet, the two will loosen due to long-term work, resulting in water leakage. For this reason, we provide a leak-proof water inlet pipe structure. Utility Model Content
