After the pipe is connected, the pipe and joint are not firmly connected. To this end, the applicant applied for a compressed air quick pipe joint (application number: 200810063105. 6 filing date: 2008-07-10), the pipe joint includes a joint pipe and an end cap, and the end cap and the joint pipe are detachable by threads Connection, the end of the joint pipe is provided with a snap ring seat; the inner end of the snap ring seat extends into the joint pipe and is provided with a sealing ring against the snap ring seat, and the inner ring of the seal ring protrudes from the inner diameter of the snap ring seat The outer end surface of the snap ring seat is provided with a metal elastic snap ring. The elastic snap ring includes a ring body and claw teeth. The claw teeth are turned toward the snap ring seat, and a bevel ring is arranged at the opening of the snap ring seat. The teeth are arranged on the inclined ring; the outer end of the elastic snap ring is provided with a pushing member, and the two ends of the pushing member respectively abut against the elastic snap ring and the boss.

The patented pipe joint has the characteristics of simple structure, convenient implementation and firm connection.
上述的管接头连接在连接小直径输送管路中有一定的优势， 但是如果 涉及到的是大型的压縮空气管路系统， 这样就需要大直径的输送管路和小 直径的输送管路配合使用， 上述专利的管接头在应用于较大直径管路的时 候， 管接头就需要做的体积较大， 这样对连接就不是很方便， 生产的成本 也相应的提高。 The above-mentioned pipe joint connection has certain advantages in connecting small-diameter conveying pipes, but if a large-sized compressed air pipe system is involved, it is required to cooperate with a large-diameter conveying pipe and a small-diameter conveying pipe. When the pipe joint of the above patent is applied to a large-diameter pipe, the pipe joint needs to be made to have a large volume, so that the connection is not very convenient, and the production cost is low.
