Preferred version of the present utility model is:
Further, the internal surface of assembling card one end is provided with assembling card internal projection.
Further, assembling card be provided with assembling card internal projection one end end face along the circumferential direction decile be arranged with several radial grooves.
Further, the outer surface of assembling card is provided with outer tapered assembling card convex platform, internal surface in female joint main body is provided with inner concave shape female joint table top, and when the radial groove of assembling card is stressed while being retracted to predetermined station, assembling card convex platform and described female joint table top fit tightly.
Further, one end inwall that special-shaped seal ring is fixed on tool joint pin main body inner wall is provided with circular seal ring projection, and the pass of diameter r1, the r2 of the diameter r of described seal ring projection and bellows crest, trough is r2≤r≤r1.
Further, also comprise positioning ring, described positioning ring is socketed in the externally threaded bottom of described female joint main body.
Further, on the outer wall of described female joint main body, be also provided with Leak testtion through hole.
The utility model beneficial effect is: this bellows Quick-acting type mounting joint that the utility model provides, during assembled in situ, without carrying special-purpose end portion treatment instrument, delivery pipe is carried out to end portion treatment, only delivery pipe need be inserted by joint uropore, with assembling card cutting ferrule, threaded together joint can be realized quick assembling; When being covered with the inipple feeding of delivery pipe, can make special-shaped seal ring and inclined-plane and the radial direction Double Pressures laminating of corrugated tube end at first ripple contacting, realize joint and delivery pipe safety, reliable sealing.
