Specific embodiment
As shown in Figs. 1-5, a kind of fast joint of stainless steel water supplying pipe mainly includes joint body 1, nut 2, band notch 31
Buckle 3 and sealing ring 4.
The connecting pin 11 for connecting with stainless steel water supplying pipe 5, connecing in this diagram are provided on the joint body 1
Head ontology is threeway, and the connecting pin 11 of setting is three, can be in practice two or more according to joint body prominent form
It is multiple.
Isometrical connecting hole 111 is provided in the connecting pin 11, the bottom of connecting hole 111 is provided with stop bit boss
1111, stop bit boss 1111 offsets with the top of stainless steel water supplying pipe 5 in assembly and connect.It is arranged on the hole wall of connecting hole 111
There is at least one of mounting groove 1112, is equipped with a sealing ring 4, the mounting groove being arranged in this diagram in each mounting groove 1112
1112 be twice, and it is one or more for being set as needed in practice.Here, connection sealing can be with sealing ring 4
Quantity is proportional, and optimal number is two.The oral area of the connecting hole 111 is provided with a cooperation inclined-plane 1113.The connection
The outside at end 11 is provided with connection external screw thread 112 and can connect with the nut 2.
The buckle is provided with notch 31 3 between nut 2 and connecting pin 11, buckles 3 initial inside diameter and is greater than
The outer diameter of stainless steel water supplying pipe 5 is less than not being squeezed Shi Qike by external force and realizing to inside contract by existing notch 31 with acquisition
The internal diameter of rust 5 outer diameter of steel water supplying pipe.
The front end of buckle 3 is provided with front bevel 32 and the cooperation inclined-plane 1113 of 111 oral area of connecting hole offsets, after buckling 3
End is provided with back bevel 33 and offsets with the extruding inclined-plane 21 inside nut 2.
The inward turning of 2 opposing attached end 11 of nut will push and squeeze buckle 3 and inside contracts and hold stainless steel water supplying pipe 5 tightly.
Here, the operative constraint after assembling for realization stainless steel water supplying pipe 5 in the axial direction, the stainless steel water supplying pipe 5 exist
The position of corresponding buckle 3 is equipped with annular groove 51, once buckle 3 inside contracts and is caught in the annular groove 51 and can be realized to stainless steel water supplying pipe
5 axial limiting.
The inner wall of buckle 3 is provided with the thread protrusion 34 for increasing frictional resistance, can further enhance 3 pairs of stainless steels of buckle
The locking of water supplying pipe 5 connects.
When assembly, sealing ring 4 is put into the mounting groove 1112 of connecting hole 111 first, is put into buckle 3 later, and will
Nut 2 screws in a part.Then go out corresponding annular groove 51 close to end position card on stainless steel water supplying pipe 5, then by it
From 2 inner hole of nut be inserted into, and pass through buckle 3 after enter connecting hole 111 in, the process until stainless steel water supplying pipe 5 end with
The stop bit boss 1111 of 111 bottom of connecting hole offsets stop bit, leads between the outer wall of stainless steel water supplying pipe 5 and connecting hole 111 at this time
It crosses sealing ring 4 and realizes effective sealing.Last tightening nuts 2, which push in buckle 3, to be moved, and in the process, utilizes buckle back bevel 33
Buckle 3 is inside contracted using the extruding reaction of buckle front bevel 32 and cooperation inclined-plane 1113 with the squeezing action for squeezing inclined-plane 21
Locking is held tightly into annular groove 51, and connection is locked while to realize that stainless steel water supplying pipe 5 is radial and axial upper, completes dress
Match.
In the above structure, the sealing ring 4 being fully utilized in connecting hole 111 is realized effective with stainless steel water supplying pipe 5
Sealing, inside contracting to hold tightly and realize and be fixedly connected with the effective of stainless steel water supplying pipe 5 using notch buckle 3, entire connection procedure without
