Enter the described snap-fit grooves 121 of described card interface 12, so to 2 circumferential and axial fixations of described fastener；Described arc
Shape slide rail 22 is easy on described cambered way 122 slide；Under described sector, teat 23 is used for coordinating described safety clamping described
First annular protruding the 32 of male joint 3, are placed in the first annular front side of protruding 32；Described arch jut 24 is for described buckle
Part 2 departs from card interface 12, and along with the contracting of self afterbody drives the oblique contracting of described empennage 25, makes fastener 2 take off the most smoothly
From card interface 12；Described empennage 25 is gradually reduced to afterbody thickness from head, and this is easy to empennage 25 and shrinks in the diagonal, and has extensive
Restore the elasticity of shape.
As shown in Figure 5 and Figure 6, the Access Division 33 in male joint is easy to teat 23 under the sector of described fastener 2 and is fitted together to, from
And coordinate safety collar 133 to be clamped by described first annular projection 32, finally realize male joint 3 and the female joint of quick connector
The connection of 1；Described second annular projection 34 is for the outer wall of described female joint 1 of fitting, and plays the role of positioning；Described first flexible pipe
Connecting portion is nipped corresponding hose inner wall by the anti-skidding projection of annular thereon, thus realizes connecting.When described male joint 3 second
Annular protrusion 34 touches the front end face of described female joint 1, and the corresponding first annular rear end face of protruding 32 fits to described peace
The front end face of loopful 133, such assembly crewman sees that described male joint 3 has been inserted into rigging position, puts at described card interface 12
Entering described fastener 2, under the sector of described fastener 2, the rear end face of teat 23 fits to the first annular convex of described male joint 3
Playing the front end face of 32, so, described male joint 3 is inserted into described female joint part card jail in the inside of described female joint, it is achieved
Connecting, first annular protruding the 32 of described male joint are by before and after teat 23 under the sector of described fastener 2 and described safety collar 133
Clamping, inserts described female joint part to described male joint and carries out axial restraint, prevent its axial float.
As shown in Figure 7, Figure 8 and Figure 9, described fastener 2 is different relative to teat 23 thickness under described sector, thickness difference portion
Divide the described arc-shaped slide rail 22 being exactly to slide on described cambered way 122 for described fastener 2, thus similar material power
Simply supported beam in, makes beam generation amount of deflection recessed by applying concentration power, and in like manner, the cambered way 122 of described card interface 12 is to institute
Stating fastener to play a supportive role, the two ends of similar simply supported beam support seat, so, are pressed the square of described fastener 2 by thumb
Shape is protruding so that it is have recessed in the middle of in elastic range, so that the engaging head 21 of described fastener 2 moves down, departs from
Snap-fit grooves 121 in described female joint, and utilize friction so that described fastener 2 retreats along described cambered way 122,
The engaging head 21 of the most described fastener 2 exits described snap-fit grooves 121.By two fingers arch to described fastener 2
The afterbody of teat 24 applies power the most inwards, the afterbody of described arch teat 24 so can be made the most tiltedly to contract, drive institute simultaneously
State empennage 25 the most tiltedly contracting, so that described empennage 25 is from 123 removals of described cover plate, the most upwards exerts a force, make buckle
Part 2 departs from the female joint 1 of described 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-selection
In 1, then the public connecting tube 31 of male joint 3 is sequentially passed through safety collar 133, sealing ring and inner shield ring 132, in male joint 3
First annular protruding 32 fit with safety collar 133, then two card interfaces from female joint 1 respectively by two fasteners 2
Put into, teat 23 under the sector of fastener 2 is conflicted on the Access Division 33 of male joint 3, thus male joint 3 is locked in female joint
On 1；Wherein fastener 2 is installing when, first by empennage 25 through the breach 124 on cover plate 123, then by fastener 2
Engaging head 21 be connected in snap-fit grooves 121, i.e. complete 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 tube
Termination, such as the metal tube of fuel conduit.But, quick connector can also be with rigid plastic material or other conventional notes
Mold materials is made, to be connected in the usual way with hose line or pipeline.
