Embodiment
As shown in Figure 1 and Figure 2, the rapid pipe joint of the utility model airduct, comprises sleeve 1, plug 2, and sleeve 1 connects one end of airduct 10, and plug 2 connects the other end of airduct 10;
Sleeve 1 comprises attaching nut 1-1, and the head of attaching nut 1-1 is fixedly connected with maincenter 1-2 by outside thread, and the afterbody of attaching nut 1-1 is formed for connecting the taper joint of airduct 10 ends; The rear portion of attaching nut 1-1, by outside thread attaching nut joint 1-10, is arranged with spring 1-11 on nut connector 1-10; The tail end of nut connector 1-10 is provided with and protects spring 1-12;
The front end movable sheath of maincenter 1-2 is provided with overcoat 1-4, is provided with maincenter external pressure spring 1-5 between maincenter 1-2 and overcoat 1-4; Overcoat 1-4 can axially moving forward and backward along maincenter 1-2; In overcoat 1-4, be provided with back-up ring 1-6;
The front end edge of maincenter 1-2 circumferentially offers a plurality of steel bead grooves, is equipped with steel ball 1-7 in steel bead groove;
Overcoat 1-4 can drive back-up ring 1-6 motion in mobile process, makes back-up ring 1-6 implement location to steel ball 1-7;
The inner chamber of maincenter 1-2 is movably set with spool 1-3, and the front portion of spool 1-3 is for attachment plug 2; The inner ring of spool 1-3 is set side by side with gasket seal 1-13 and O type circle 1-14, for the sealing between spool 1-3 and plug 2;
Between spool 1-3 and maincenter 1-2, be provided with stage clip 1-8 in maincenter; Spool 1-3 can move forward and backward vertically in maincenter 1-2;
Under original state, the front end of spool 1-3 props up steel ball 1-7, and steel ball 1-7 is remained in steel bead groove;
Spool 1-3 is connected with attaching nut 1-1 by connecting gaily decorated basket 1-9.
Plug 2 comprises pipe joint 2-1, and the rear portion of pipe joint 2-1, by outside thread attaching nut joint 2-2, is arranged with spring 2-3 on nut connector 2-2; The tail end of nut connector 2-2 is provided with and protects spring 2-4; The afterbody of pipe joint 2-1 is formed for connecting the taper joint of airduct 10 ends;
The front portion of pipe joint 2-1 is formed for the annular slot 2-11 to steel ball 1-7 axially locating in assembly process.
The body of airduct 10 adopts elastic material, while not using at ordinary times, there will not be the phenomenon that airduct is at random, and can save placement space.
Working principle of the present utility model is as follows:
Being connected between sleeve 1 and plug 2:
As shown in Figure 3, pipe joint 2-1 is inserted in maincenter 1-2, along with entering of pipe joint 2-1, pipe joint 2-1 is by spool 1-3 (from right to left) promotion being backward arranged in maincenter 1-2, make the front end of spool 1-3 leave steel ball 1-7, steel ball 1-7 falls thereupon, falls in the annular slot 2-11 of pipe joint 2-1;
Then pull overcoat 1-4 to move forward (from left to right), overcoat 1-4 drives back-up ring 1-6 to move, back-up ring 1-6 is stuck in the outer ring of steel ball 1-7, thereby the circumferential position of restriction steel ball 1-7, make steel ball 1-7 stuck in the position of annular slot 2-11, thereby realize the quick assembling between sleeve 1 and plug 2;
When plug 2 assembles with sleeve 1, by gasket seal 1-13 and O type circle 1-14, form two seals.
Separated between sleeve 1 and plug 2:
Pull overcoat 1-4 to move backward, the inwall of overcoat 1-4 no longer withstands back-up ring 1-6, back-up ring 1-6 extends out, steel ball 1-7 is no longer stuck in annular slot 2-11, in maincenter under the effect of stage clip 1-8, spool 1-3 outwards ejects pipe joint 2-1, make the gasket seal 1-13 originally matching with the front end of pipe joint 2-1 depart from pipe joint 2-1, but the existence due to O type circle 1-14, now pipe joint 2-1 does not spin off completely in sleeve 1, still keeping sealing, therefore even if gasket seal 1-13 is damaged because of other reasons, also without worrying that the unexpected leakage due to gas meets accident in using air gun process, if need to make pipe joint 2-1 spin off in sleeve 1 completely, only need exert oneself again pipe joint 2-1 outwards to pull.
