Embodiment

Below in conjunction with accompanying drawing, and the utility model is described further through specific embodiment.

To shown in Figure 6, the fast access node structure of quick detach for a kind of pipe fitting of the utility model mainly is made up of joint 1, joint chair 2, fixed cover 3, buckle 4 and elastic component 5 like Fig. 1; Wherein:

One end of this joint 1 forms the connecting part 11 that is complementary and is connected with outer tube; The other end forms cutting graftage part 12; The middle part of joint 1 is that one to run through two ends be connecting part 11 and the through hole 13 of cutting graftage part 12; Be interval with first,

second ring flange

14,15 on the outer wall of this cutting graftage part 12, first, second ring flange 14, be defined as neck 16 between 15;

One end of this joint chair 2 has the joint 21 that is complementary and is connected with outer tube; The other end is belled part 22; The middle part of this belled part 22 is provided with the trepanning 23 that is complementary with joint cutting graftage part 12, and trepanning 23 supplies the cutting graftage part 12 of joint to be inserted in the formation socket, and this trepanning 23 communicates with joint 21; Again the sidewall of belled part 22 on the position of corresponding joints neck 16 axially symmetry offer two be communicated with trepannings side opening 24, the further below of side opening 24 protrusion one retaining wall 25;

These fixed cover 3 middle parts are for connecting mesopore 31 up and down; The belled part 22 of the pore size coupling joint chair of this mesopore 31 supplies the belled part 22 of joint chair sheathed, and moulding one is communicated with the slot 32 of mesopore in the fixed cover; Slot 32 has an opening 321, protrusion two blocks 322 of the inwall symmetry of slot 32; Buckle 4 combines elastic component 5 to be located in the slot 32 of fixed cover 3; Extend two elastic arms 41 on this buckle 4; The terminal inboard fixing face 42 that forms of two elastic arms 41, the outside is provided with overhead kick 43, and buckle 4 is inserted by the opening 321 of slot; After making the end of two elastic arms 41 pass the block 322 of slot, fasten block 322 by the overhead kick 43 in elastic arm 41 outsides and prevent; The two ends of elastic component 5 are resisted against slot 32 and buckle 4 respectively; The effect of elastic component 5 remains and the cooperating of slot block 322 overhead kick 43 of elastic arm 41 under the influence that does not have external force; Push buckle 4 compressible elastomeric spares 5, two elastic arms of buckle 4 are moved inward along slot 32.

During assembling, at first be inserted in the belled part 22 of joint chair in the mesopore 31 of fixed cover 3 and be limited in retaining wall 25, make the terminal fixing face 42 of 4 liang of elastic arms of buckle appear behind the location and part convexedly stretches in the trepanning 23 of joint chair by the two side holes 24 of joint chair; During connection; Push buckle 4, the fixing face 42 that drives buckle two elastic arms in slot when buckle compression elastic piece 5 is moved breaks away from the two side holes 24 of joint chair, the cutting graftage part 12 of joint 1 is inserted in the trepanning 23 of joint chair again; And the neck 16 that makes joint 1 is on the position of joint chair two side holes 24; Loosen buckle 4, buckle 4 resets under the resilient force of elastic component 5, makes the terminal fixing face 42 of two elastic arms appear the neck 16 of holding joint 1 tightly by the two side holes 24 of joint chair; With permanent joint 1, the completion joint docks with joint chair.During fractionation, push buckle 4 equally buckle compression elastic piece 5 is moved in slot, and drive the two side holes 24 that the fixing face 42 that makes buckle two elastic arms breaks away from neck 16 with the joint chair of joint 1, can the trepanning 23 of joint 1 by joint chair be withdrawed from.It is thus clear that the utility model adopts said structure, can realize quick connection and fractionation between pipe fitting, and it is also very easy to operate, and need not tool using.

In addition, be provided with seal ring 26 in the trepanning 23 of above-mentioned joint chair 2; The lower end of above-mentioned joint 1 first ring edge 14 can be established and is inverted cone surface 141; The first ring edge 14 can be accomplished connection through the fixing face 42 of two elastic arms by force under inverted cone surface 141 guidings; The setting of inverted cone surface 141 can make joint 1 when connecting, need not push buckle 4, and is simpler, quick in the operation.
