Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:
Embodiment: as shown in Figure 1 to Figure 3, the self-locking quick quick coupling in the present embodiment comprises main lock body 1, cutting ferrule portion and spool portion.Main lock body 1 is the cylinder that a center connects.Spool portion is located at its inside from an end of main lock body 1, thereby forms a negative joint at this end.Cutting ferrule portion is placed in its outside from the other end of main lock body 1, under unlock state, this the other end place can patch male connector 4, thereby utilizes the utility model to realize that male connector 4 is connected and disconnection fast with the quick of self-locking quick quick coupling (being male connector 4 and negative joint).
Cutting ferrule portion comprises outer cutting ferrule 31, interior cutting ferrule 33, cutting ferrule spring 32, pad 35, back-up ring 34, the O of cutting ferrule portion type circle 36, blind hole lock pearl 38 and a plurality of taper hole lock pearl 37.
The outside of cutting ferrule 33 in outer cutting ferrule 31 is located at, under unlock state, interior cutting ferrule 33 can move axially.Cutting ferrule spring 32 axially supports and is located between outer cutting ferrule 31 and the interior cutting ferrule 33.
The outside of main lock body 1 is provided with taper hole 11 and blind hole 12 that a circle radially connects, and this taper hole 11 is holes that radially inwardly dwindle, and falls into the inside of main lock body 1 from taper hole 11 to prevent taper hole lock pearl 37.The quantity of taper hole lock pearl 37 and the sum of taper hole 11 are complementary and place in the taper hole 11, taper hole lock pearl 37 can be adopted steel ball, on the outer wall at male connector 4 places, be provided with a circle groove, groove and taper hole lock pearl 37 are complementary, when male connector 4 patches negative joint, taper hole lock pearl 37 be able to snap in the groove, thereby plays the quick effect that is connected of male connector 4 and negative joint.
Back-up ring 34 is one to be set in the C type ring of main lock body 1 outside, and is provided with corresponding locating slot 13 in the end of interior cutting ferrule 33 inwalls, and it plays the axially locating effect when interior cutting ferrule 33 moves axially, thus cutting ferrule 33 axially movable scopes in the restriction.
The O of cutting ferrule portion type circle 36 and pad 35 are arranged on the place, outer ring of spool chamber inboard (end of negative joint), behind grafting male connector 4, can tightly touch the outer ring of male connector 4, thereby play the effect of leakproof in the joint of yin, yang joint.
Spool portion comprises spool 22, the O of spool portion type circle 21, valve core spring 23, spring seat 24 and collar 25.Spool portion is located at the inside of main lock body 1, and the inwall of main lock body 1 is provided with the spool chamber that the nose shape with spool 22 is complementary in the side that spool portion is installed, and promptly forms a negative joint.The spool chamber of main lock body 1 opposite side then can connection pipe coupling to be connected, and promptly male connector 4.
The O of spool portion type circle 21 is sheathed on the spool 22 and with the inwall of main lock body 1 to be close to, thereby plays the effect of leakproof.Collar 25 is fixed on spring seat 24 in the main lock body 1.
Valve core spring 24 axially support establish and spool 22 and spring seat 24 between, make spool 22 have the trend of the inwall of being close to spool chamber, make spool 22 can be close to the inwall of the spool chamber of main lock body 1 one sides just.
During use, when interior cutting ferrule 33 is promoted outward, blind hole lock pearl 38 on the main lock body 1 in the blind hole 12 enters the circular groove 331 of interior cutting ferrule 33 and fastens with circular groove 331, cutting ferrule 33 in the rotation makes blind hole lock pearl 38 depart from vertical slot 332, thereby with interior cutting ferrule 33 lockings, rapid pipe joint locking this moment, thereby promptly outer cutting ferrule 31 can not move extruding all the time to the inside and live taper hole lock pearl 37, and this moment, male connector 4 can't squeeze out taper hole lock pearl 37, can not be connected fast with negative joint and disconnect fast.
Cutting ferrule 33 in rotation, make blind hole lock pearl 38 aim at vertical slot 332, this moment is when can be with interior cutting ferrule 33 mobile to the inside, pearl 38 enters in the perpendicular shape groove of interior cutting ferrule 33 the blind hole lock, interior cutting ferrule 33 and outer cutting ferrule 31 can axially move, rapid pipe joint no longer is in the lock state, and this moment, the yin, yang joint can connect and disconnection fast fast.Particularly, when connecting fast, outer cutting ferrule 31 moves to the inside, male connector 4 can patch with negative joint, the spool of yin, yang joint and valve core spring are respectively to two side shiftings, and spool O type circle 21 is away from main lock body 1 inwall, and liquid can flow by main lock body 1, outer cutting ferrule 31 after finishing is because the spring return that is subjected to cutting ferrule spring 32, guarantees the safety connection of yin, yang joint to the home position; When disconnecting fast, move outer cutting ferrule 31 to the inside, by the effect of valve core spring 23, the yin, yang joint disconnects fast, and spool O type circle 21 moves up once more tight card in main lock body 1 inwall, and liquid can not flow by main lock body 1.
