The Pipe joining method for using the pipe fitting in relation to embodiment 1 is illustrated using attached drawing.Fig. 5 is signal earth's surface
It is shown with the perspective view by the state before the 1st pipe and the insertion of the 2nd pipe when the interim engaging for closing the pipe fitting of embodiment 1.
Fig. 6 is that the 1st pipe and the 2nd are managed to the shape after just insertion when showing schematically the interim engaging of the pipe fitting in relation to embodiment 1
The perspective view of state.In addition, please referring to FIG. 1 to FIG. 4 about there is no the part indicated in Fig. 5 and Fig. 6.
Firstly, the 1st seal member 60 is attached in the 1st stage portion 31 of tubular part 30, and by the 2nd seal member 70
It is attached to (step A1 in the 2nd stage portion 32；Referring to Fig.1, Fig. 3).
Then, tubular part 30 is partially accommodated to the 1st through hole 43 and the 2nd body 50 to the 1st body 40
1st body 40 and the 2nd body 50 are assembled (step A2 by the mode in the 2nd through hole 53；Referring to Fig.1, Fig. 3).At this point, the 1st body
Body 40 and the 2nd body 50 are the interim states for engaging and not engaging.
Then, slide the 1st body 40 and the 2nd body 50 in mode close to each other, by the 4th claw 52b and the 1st slot
Portion 41b temporarily engages, and the 3rd claw 42b is temporarily engaged (step A3 with the 2nd socket 51b；Referring to Fig. 5, Fig. 3).At this point,
Although the 1st body 40 and the 2nd body 50 are the interim states for engaging but not engaging completely.
Then, the 1st protrusion 41c is pushed into radially inner side, the 2nd slit 55 is opened, by the third portion of the 2nd pipe 20
21 are inserted into the 2nd through hole 53 from the 2nd opening portion 54, are inserted into (step A4 from the other end to tubular part 30；Referring to Fig. 6, figure
3).At this point, although the 1st body 40 and the 2nd body 50 are the interim states for engaging but not engaging completely.
Then, the 2nd protrusion 51c is pushed into radially inner side, the 1st slit 45 is opened, by the part 1 of the 1st pipe 10
11 insert from the 1st opening portion 44 to the 1st through hole 43, are inserted into (step A5 from one end to tubular part 30；Referring to Fig. 6, Fig. 3).
At this point, although the 1st body 40 and the 2nd body 50 are the interim states for engaging but not engaging completely.In addition, step A5 can also be with
It is first carried out than step A4.
Then, the 1st body 40 and the 2nd body 50 are slided further in mode close to each other, by the 1st claw 42a with
2nd window portion 51a engaging, and the 2nd claw 52a is engaged into (step A6 with the 1st window portion 41a；Referring to Fig. 2, Fig. 3), terminate.By
This, becomes the state sealed via the 1st seal member 60, the 2nd pipe 20 and tubular part 30 between the 1st pipe 10 and tubular part 30
Between become the state that seals via the 2nd seal member 70, become the state for being closely attached the 1st pipe 10 and the 2nd pipe 20.This
When, the 1st body 40 and the 2nd body 50 are the interim states for engaging and engaging completely.
In addition, in the case where the 1st pipe 10 is separated with the 2nd pipe 20, if with the sequence of Pipe joining method on the contrary into
Row.
According to embodiment 1, due to being not required to it is noted that the 1st pipe 10 and the 2nd pipe 20 and the 1st body 40 and the 2nd body 50
Corresponding relationship, so can be simply assembled there is no mistake.Further, since can be by the 1st body 40 and the 2nd body
50 are made into identical construction, the 1st seal member 60 and the 2nd seal member 70 are made into identical construction, so can reduce system
Make burden.In turn, simply engaged since the 1st body 40 and the 2nd body 50 can be made to slide, so easily disposed.
Further, since will not need to be brazed or weld in the 1st pipe 10 and the connection of the 2nd pipe 20, so not needing professional people
The highly difficult operation of member, anybody can simply carry out operation.In addition, by close with the 1st seal member 60 and the 2nd
It seals component 70 to seal, the stable quality of sealing.The maintenance that periphery is not needed when by the 1st pipe 10 and the connection of the 2nd pipe 20, can
Mitigate manufacture burden.In addition, even if making the 1st pipe 10 and the different material (for example, aluminium and copper) of the 2nd pipe 20, it also can not be straight
It contacts and connects, so being connected without galvano-cautery.Further, since the 1st pipe 10 and the 2nd pipe 20 also can upon connection
Rotation, so being easy layout.
In turn, the 1st pipe 10 and the 2nd pipe 20 are torn open due to that can will be released with the engaging of the 1st body 40 and the 2nd body 50
Dress, so being easy maintenance.In addition, reducing working hour, and the stay in grade leaked compared with the flaring nut mode of status.
In addition, by the way that the 1st body 40 and the 2nd body 50 are made into identical construction, if prepare for the 1st body 40 and
2nd body 50 common 1 is framed, as long as preparing 1 data using 3D printer, so
It can reduce manufacture burden.
[embodiment 2]
The pipe fitting in relation to embodiment 2 is illustrated using attached drawing.Fig. 7 is to show schematically related embodiment 2
Pipe fitting the 2nd body and tubular part construction, by pass through central axis CA in a manner of along Y-direction cutting when section view
Figure.
Embodiment 2 is the variation of embodiment 1, is structure below: on the 2nd through hole 53 of the 2nd body 50
2nd pressing portion 53a (part of the 1st through hole 43 about the 1st body 40 for being equivalent to Fig. 3 is also the same) is set, in tubular portion
The 1st stage portion (be equivalent to Fig. 3 31) and the 2nd stage portion (be equivalent to Fig. 3 32) are eliminated on part 80, without using the 1st sealing
Component (be equivalent to Fig. 3 60) and the 2nd seal member (be equivalent to Fig. 3 70).
2nd through hole 53 has the 2nd pressing portion 53a, and the 2nd pressing portion 53a is in the 1st body (be equivalent to Fig. 3 40)
When engaging with the 2nd body 50, tubular part 80 is pushed to radially inner side, the pipe of tubular part 80 and the 2nd can be made (to be equivalent to figure
The 20 of 3) third portion (be equivalent to Fig. 3 21) keep contiguity state.2nd pressing portion 53a is when the 1st body (is equivalent to figure
The 40 of 3) (be as shown in Figure 7 throughout the circular conical surface that complete cycle is pushed to radially inner side by tubular part 80 when engaging with the 2nd body 50
The circular conical surface of L1 < L2).2nd pressing portion 53a is configured to, and the covering the 2nd of tubular part 80 is managed to the portion of (be equivalent to Fig. 3 20)
At least part covering divided.
It is also same as the 2nd through hole 53 about the 1st through hole (be equivalent to Fig. 3 43), there is the 1st pressing portion (not scheme
