As improvement, the other end of said head end joint is provided with birdsmouth, and the other end of said end connector is provided with interface, and said birdsmouth diameter is greater than said interface diameter.During connection, bellows interface one end is inserted another root bellows birdsmouth one end, thereby two bellowss are together in series.
As improvement, said birdsmouth internal surface is provided with tapering, and said interface outer surface is provided with corresponding tapering, makes things convenient for the cooperation that is connected between birdsmouth and the interface.
For solve the problems of the technologies described above two, the technological scheme of the utility model is: a kind of bellows head end joint, the end surfaces that said head end joint and bellows connect is provided with the spiral chute that agrees with mutually with bellows head end helical otch.Owing to adopt spiral helicine otch to be connected cooperation with spiral chute between bellows and the joint, bellows can make bellows firm basically with being connected of head end joint with after the head end joint cooperates; And then weld in the joint of joint and pipeline, joint and pipeline are reached be completely fixed.The bellows of this kind structure and the Placement of joint are convenient and swift, help to enhance productivity.
As improvement, the other end of said head end joint is provided with birdsmouth, and the pipeline that is used to connect is used.
As improvement, said birdsmouth internal surface is provided with tapering.
For solve the problems of the technologies described above three, the technological scheme of the utility model is: a kind of bellows end connector, the end surfaces that said end connector and bellows connect is provided with the spiral chute that agrees with mutually with bellows tail end helical otch.Owing to adopt spiral helicine otch to be connected cooperation with spiral chute between bellows and the joint, bellows can make bellows firm basically with being connected of end connector with after end connector cooperates; And then weld in the joint of joint and pipeline, joint and pipeline are reached be completely fixed.The bellows of this kind structure and the Placement of joint are convenient and swift, help to enhance productivity.
As improvement, the other end of said end connector is provided with interface, and the pipeline that is used to connect is used.
As improvement, said interface outer surface is provided with tapering.
The beneficial effect that the utility model is compared with prior art brought is:
Owing to adopt spiral helicine otch to be connected cooperation with spiral chute between bellows and the joint, bellows can make bellows firm basically with being connected of head end joint and end connector with after head end joint and end connector cooperate; And then weld in the joint of joint and pipeline, joint and pipeline are reached be completely fixed.The bellows of this kind structure and the Placement of joint are reliable, and convenient and swift, help to enhance productivity.
