Description

Technical Field

[0001] The utility model belongs to the technical field of copper pipe connection, and in particular relates to an anti-loosening copper pipe interface. Background Art

[0002] Copper tube is also called red copper tube. It is a kind of non-ferrous metal tube, which is a pressed and drawn seamless tube. Copper tube has good electrical and thermal conductivity. It is the main material for the conductive accessories and heat dissipation accessories of electronic products, and has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper tubes have strong corrosion resistance, are not easy to oxidize, and are not easy to react chemically with some liquid substances, and are easy to bend. The existing copper tube connection methods mainly include welding, crimping and threaded connection. Among them, welding connection requires the use of professional tools and skills, and the operation is relatively complicated; crimping connection is to use mechanical pressure to make the copper tube and the connector tightly combined to form a seal. Although the operation is simple, it may cause pressure loss and deformation to the copper tube; and threaded connection is to process threads at the end of the copper tube and connect it with other threaded pipes or equipment. The processing process is more troublesome and prone to leakage. In view of the above problems, the utility model proposes a new type of anti-loosening copper tube interface, which is suitable for copper tube connections in various complex environments and usage scenarios. The interface can achieve a tight connection at the copper pipe mouth without the need for welding or rubber sealing processes, ensuring a stable and reliable connection.
