Specific implementation mode
Further details of elaboration is made to the utility model below in conjunction with the accompanying drawings.
Refering to fig. 1 to Fig. 5.
A kind of quick connector, including connector 1 further include bushing 4, liner 5, pneumatic clamp spring 6, baffle ring 7 and sealing ring
8；1 one end of the connector is connected with connector 2, and the guide duct 9 being integrated with itself is equipped on the inside of the other end；The connector 2
For copper sleeve or iron connector；The connector 1 its equipped with 9 end of guide duct successively open from inside to outside fixed annular groove 11, sealing
Annular groove 12 and clamping annular groove 13；The clamping annular groove 13 is clamped with bushing 4；The baffle ring 7 is fixed on clamping ring by bushing 4
13 top of slot；The liner 5, which can slide vertically, to be inserted in bushing 4；5 top of liner is equipped with spacing ring 21,4 top inner side of bushing
It is provided with limited ring groove corresponding with spacing ring 21 22；The pneumatic clamp spring 6 is connected between baffle ring 7 and spacing ring 21；It is described
Sealing ring 8 is installed in closure gasket groove 12；The pneumatic clamp spring 6 includes being stuck in the wild card tooth ring plate 31 of 4 inner wall of bushing and interior
Card tooth ring plate 32；The wild card tooth ring plate 31 is outer to be tilted upward, and Nei Kaya ring plates 32 are inner to be tilted upward；The spacing ring 21
Upper end is butted on 32 lower section of Nei Kaya ring plates, and lower end is butted on above 22 bottom wall of limited ring groove.
Specifically, 4 inside of the bushing is provided with decontamination annular groove 14.
Specifically, 8 outside of the sealing ring is equipped with the sealing ring 41 being integrated with itself, inner wall is First Transition wall 42；
The First Transition wall 42 is the round platform side wall that port diameter is more than upper port diameter.
Specifically, 7 inner wall of the baffle ring is equipped with the second transition wall 43, second transition wall 43 is that port diameter is big
In the round platform side wall of upper port diameter.
Specifically, the connector 1 is engineering plastics connector.
Operation instruction：When the utility model is used, hose is inserted by 5 lower end of liner, sequentially passes through liner 5, pneumatic clamp spring
