Referring to fig. 2 and 3, in order to facilitate the connection of the metal braided hose 120 to the connecting pipe body 110, in another embodiment, the metal braided hose 120 further includes a connection ring 150, and the connection ring 150 is disposed at one end of the metal braided hose 120 and is used for connecting the connecting pipe body 110.

The connection ring 150 may be disposed in a circular ring shape, or may be disposed in a square ring shape, without any particular limitation. The connection ring 150 is connected to the metal braided hose 120 in many ways, for example, one end of the connection ring 150 near the corrugated tube 130 extends into the corrugated tube 130, so that the corrugated tube 130 is sleeved outside the connection ring 150. For another example, the end of the connection ring 150 near the bellows 130 is provided with a groove, and the bellows 130 is mounted in the groove. In this embodiment, by snapping the bellows 130 into the groove and filling solder into the groove, the welding strength between the bellows 130 and the connection ring 150 can be ensured, thereby improving the connection sealing property between the bellows 130 and the connection ring 150.

Considering that the braid 140 is disposed on the outer surface of the corrugated tube 130, and the outer surface of the corrugated tube 130 is not a plane, a contact area between the braid 140 and the corrugated tube 130 is small, which may result in weak connection strength between the braid 140 and the corrugated tube 130, and in order to further improve the connection strength between the braid 140 and the corrugated tube 130, optionally, the metal braided hose 120 further includes a fixing ring 160, the fixing ring 160 is sleeved outside the connecting ring 150, the braid 140 extends toward the connecting ring 150 to form a connecting portion 141, and the connecting portion 141 is sandwiched between the connecting ring 150 and the fixing ring 160. Here, it should be noted that by providing the fixing ring 160, the metal woven hose 120 is also attached to the inner peripheral surface of the fixing ring 160, so that the welding overlapping length is ensured, the welding quality is ensured, and the risk of refrigerant leakage in the air conditioner connection pipe 100 is reduced.

The quick coupling 180 can achieve quick connection while making the air conditioner connection pipe 100 free from vacuum pumping.

Considering that the connection pipe body 110 generally connects the indoor unit and the outdoor unit of the air conditioner, the connection pipe body 110 is exposed to the outside, and in addition, the refrigerant flowing inside the connection pipe body 110 has a certain corrosiveness, which all affect the service life of the connection pipe body 110. Therefore, in order to prolong the service life of the connecting tube body 110, please refer to fig. 4, 5 and 6, in some embodiments, a protective layer 190 is disposed on the outer surface of the connecting tube body 110. The protective layer 190 may be disposed on the outer surface of the connecting tube body 110 by sleeving, gluing, plating, spraying, or the like.

Optionally, the thickness of the protective layer 190 is 0.02mm to 0.08 mm. Since the protective layer 190 has an excessively thick thickness, the weight of the coupling pipe body 110 is heavy, it is inconvenient to assemble the coupling pipe body 110, and unnecessary material costs are wasted; if the thickness of the protective layer 190 is too thin, the protective layer 190 may have an insignificant protective effect on the connection pipe body 110, and may not extend the service life of the connection pipe body 110. Therefore, the thickness of the protective layer 190 is 0.02mm to 0.08mm, which not only can well protect the connecting pipe body 110, but also can prolong the service life of the connecting pipe body 110; meanwhile, the weight of the connecting pipe body 110 is not increased too much, and materials are saved.

Specifically, the protective layer 190 includes one or more of an anti-aging layer, an anti-condensation layer, an anti-scratch layer, and an insulating layer. Considering that the connection pipe body 110 is placed in an outdoor environment, and is exposed to wind and sunlight, and is prone to aging, and may be scratched, an anti-aging layer and an anti-scratch layer need to be disposed on the outer surface of the connection pipe body 110. In addition, since a large temperature difference exists between the temperature of the refrigerant flowing through the connection pipe main body 110 and the outdoor ambient temperature of the connection pipe main body 110, which may cause condensation on the connection pipe main body 110, in order to prevent condensation, a condensation preventing layer may be provided on the outer surface of the connection pipe main body 110, and naturally, in order to prevent a sudden change in the temperature of the refrigerant in the connection pipe main body 110 and thus an influence on the cooling effect, an insulating layer may be provided on the outer surface of the connection pipe main body 110. In this embodiment, the anti-aging layer, the anti-condensation layer, the anti-scratching layer, and the thermal insulation layer may be combined by sheathing, gluing, plating, spraying, or the like.

Further, in other embodiments, an aluminum foil layer may be further disposed on the outer surface of the protection layer 190. By providing the aluminum foil layer, the ultraviolet resistance of the connecting pipe body 110 can be effectively improved.
