With the knuckle 1212 for merging the support snap-fit grooves 121, its radius of corner is 0.2mm；The of the engaging head 21
Two inclined-planes 213 are used for the second inclined-plane 1213 for being caught in the snap-fit grooves 121, and its gradient is 45 °；The of the engaging head 21
Two fillets 214 slip into the snap-fit grooves 121 for convenient card syncephalon portion 21, and its radius of corner is 0.2mm；The engaging head
21 the 3rd inclined-plane 215 is used for the 3rd inclined-plane 215 for coordinating the clamping part 21, and its gradient is 30 °；The engaging head 21 is embedding
Enter the snap-fit grooves 121 of the card interface 12, circumferential and axial fixation so is played to the fastener 2；The arc
Shape slide rail 22 is easy to slide on the cambered way 122；The fan-shaped lower teat 23 is used to coordinate described in the safety clamping
First annular raised the 32 of pin end 3, are placed in first annular raised 32 front side；The arch jut 24 is used for the buckle
Part 2 departs from card interface 12, and as itself afterbody Inner contractings drive the oblique Inner of the empennage 25 to contract, so smoothly makes fastener 2 de-
From card interface 12；The empennage 25 is gradually reduced from head to afterbody thickness, and this is easy to 25 oblique contract of empennage, and with extensive
Restore the elasticity of shape.
As shown in Figure 5 and Figure 6, the Access Division 33 on pin end is easy to teat 23 under the sector of the fastener 2 chimeric, from
And coordinate safety collar 133 to be clamped first annular projection 32, finally realize pin end 3 and the female joint of quick connector
1 connection；Second annular projection 34 is used for the outer wall for being bonded the female joint 1, and plays the role of positioning；First flexible pipe
Connecting portion bites corresponding hose inner wall by annular anti-skid bulge thereon, so as to realize connection.When the second of the pin end 3
Annular protrusion 34 touches the front end face of the female joint 1, and corresponding first annular raised 32 rear end face fits to the peace
The front end face of loopful 133, such assembly crewman see that the pin end 3 has been inserted into rigging position, put in the card interface 12
Enter the fastener 2, the rear end face of teat 23 fits to the first annular convex of the pin end 3 under the sector of the fastener 2
32 front end face is played, so, the pin end 3 is inserted into the female joint part card jail in the inside of the female joint, realization
Connection, the pin end first annular raised 32 by before and after teat 23 under the sector of the fastener 2 and the safety collar 133
Clamp, inserting the female joint part to the pin end carries out axial restraint, prevents its axial float.
As shown in Figure 7, Figure 8 and Figure 9, the fastener 2 is different relative to the fan-shaped lower thickness of teat 23, thickness difference portion
It is exactly to be used for the arc-shaped slide rail 22 that the fastener 2 slides on the cambered way 122 to divide, thus similar material power
Simply supported beam in, by apply concentrated force make beam produce amount of deflection it is recessed, similarly, the cambered way 122 of the card interface 12 is to institute
State fastener to play a supportive role, the both ends support base of similar simply supported beam, so, the square of the fastener 2 is pressed by thumb
Shape is raised, has its own centre in elastic range recessed, so that the engaging head 21 of the fastener 2 moves down, departs from
Snap-fit grooves 121 in the female joint, and utilize friction so that the fastener 2 retreats along the cambered way 122,
The snap-fit grooves 121 are exited on the engaging head 21 of so described fastener 2.Arch by two fingers to the fastener 2
The afterbody of teat 24 applies power mutually inwards, the afterbody of the arch teat 24 is inwardly tiltedly contracted, while drive institute
The inside tiltedly contracting of empennage 25 is stated, so that the empennage 25 then smoothly exerts a force from 123 times removals of cover plate, make buckle upwards
Part 2 departs from the female joint 1 of the quick connector, completes dismounting.
The present invention installation process be：Sealing ring, inner shield ring 132 and safety collar 133 are put into female joint 1 by first choice, so
The public connecting tube 31 of pin end 3 is sequentially passed through into safety collar 133, sealing ring and inner shield ring 132 afterwards, the first ring on pin end 3
Shape projection 32 is bonded with safety collar 133, is then put into two fasteners 2 from two card interfaces in female joint 1 respectively, by card
Teat 23 is contradicted on the Access Division 33 of pin end 3 under the sector of fastener 2, so as to which pin end 3 is locked in female joint 1；Wherein
Fastener 2 is when installation, first by empennage 25 through the breach 124 on cover plate 123, then by the engaging head of fastener 2
Portion 21 is connected in snap-fit grooves 121, that is, completes the installation of fastener 2.
Present invention can apply to vehicle fuel pipeline, male connecting tube 31 and female connecting tube 13 can be durable metal tubes
Termination, such as the metal tube for fuel conduit.However, quick connector can also use rigid plastic material or other conventional notes
Mold materials is made, to be connected in the usual way with hose line or pipeline.
