Annular protrusion 34 touches the front end face of the female connector 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, are put in the card interface 12
Enter the fastener 2, the rear end face of protrusion 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, in this way, the pin end 3 is inserted into the female connector part card jail in the inside of the female connector, realization
Connection, the pin end first annular raised 32 by before and after protrusion 23 under the sector of the fastener 2 and the safety collar 133
It clamps, being inserted into the female connector 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 23 thickness of the fan-shaped lower protrusion, thickness difference portion
It is exactly the arc-shaped slide rail 22 slided on the cambered way 122 for the fastener 2 to divide, thus similar material power
Simply supported beam in, by apply concentrated force make beam generate amount of deflection it is recessed, similarly, the cambered way 122 of the card interface 12 is to institute
It states fastener to play a supportive role, the both ends support base of similar simply supported beam, in this way, pressing the square of the fastener 2 by thumb
Shape protrusion has its own centre in elastic range recessed, so as to which the engaging head 21 for making the fastener 2 moves down, is detached from
Snap-in groove 121 on the female connector, and utilize friction so that the fastener 2 is retreated along the cambered way 122,
The snap-in groove 121 is exited on the engaging head 21 of fastener 2 described in this way.By two fingers to the arch of the fastener 2
The tail portion of protrusion 24 applies power mutually inwards, the tail portion of the arch protrusion 24 can be made inwardly tiltedly to contract in this way, while drive institute
The inside tiltedly contracting of empennage 25 is stated, so as to which the empennage 25 be made then smoothly to exert a force upwards from 123 times removals of cover plate, make buckle
Part 2 is detached from the female connector 1 of the quick connector, completes dismounting.
The installation process of removable quick connector is：Sealing ring, inner shield ring 132 and safety collar 133 are put into mother and connect by first choice
In first 1, the public connecting tube 31 of pin end 3 is then sequentially passed through into safety collar 133, sealing ring and inner shield ring 132, on pin end 3
First annular raised 32 be bonded with safety collar 133, then by two fasteners 2 respectively from two card interfaces on female connector 1
It is put into, protrusion 23 under the sector of fastener 2 is contradicted on the clamping portion of pin end 3 33, so as to lock pin end 3 in female connector
On 1；Empennage 25 is passed through the notch 124 on cover plate 123, then by fastener 2 by wherein fastener 2 first when installation
Engaging head 21 be connected in snap-in groove 121, that is, complete fastener 2 installation.
Present invention can apply to vehicle fuel pipeline, male connecting tube 31 and female connecting tube 13 can be durable metal tubes
End, such as the metal tube for fuel conduit.However, quick connector can also use rigid plastic material or other common notes
