Specific embodiment [0012] combined with the following specific embodiment, the utility model is further explained: [0013] referring to figure 3 and figure 4, the manufacturer of expanded pipe joint is a kind of metal hose joint loo mentioned in this embodiment, which includes the joint body 1.The non-standard plastic connector is provided with a clamping member 4 in one end of the connector body 1 and a locking cover 6 for locking the metal hose at one end of the connector body 1.A sealing ring 2 at the other end of the joint body 1, a locking member 3, and an external rubber sealing cover 5 mounted on the clamping member 4.The outer end face of fitting 4 is provided with a connection screw 401 formed in a manner that is screwed together with the inner wall of the metal hose.Where,, the metal hose of non-standard PU tube and the thread position of connecting part 4, the lock cover 6 locks the metal hose on the joint body 1 through the rubber seal cover 5: this scheme is.By setting connection screw 401 on the outer side of card shell 4, when installing the metal hose, it can use its own screw to connect with the joint body 1 with high-speed thread. The whole process is simple, fast and reliable.In addition, the reliability of the metal hose connection can be guaranteed through the rubber sealing cover 5.In addition, the pressure joint manufacturer also includes the ring cover 7, which is made of a rubber-resistant material nested in the other end cavity of fitting body 1.By setting ring bushing 7 made of rubber wear-resistant material in the inner cavity at the other end of the joint body 1, the thickness of the inner wall can be effectively reduced under the condition of normal use of the joint body. In addition, the production cost can be reduced, especially for mass production, the economic benefits are more obvious.The embodiment mentioned above is a better embodiment of the utility model. Since it does not limit the scope of the utility model, the shape and change of the utility model according to the principle shall all be included in the scope of protection of the utility model.
