There are slope, skewed slot.
Further say, the quantity of the projection described in this utility model is 4.
Further say, the cross sectional shape of the projection described in this utility model is trapezoidal.
Further say, the quantity of the skewed slot described in this utility model is 2.
Further say, height and the cup depth phase of cutting ferrule groove that boss structure described in this utility model protrudes
Deng.
Further say, the cutting ferrule groove described in this utility model to the length between the bevel end of slope is more than pipe fitting sheet
Body slides the length at tight end.
Further say, the welding ends of the pipe fitting body described in this utility model is connected with metallic conduit, sliding tight end with
PEX pipelines connect.
Further say, the tight pipe fitting of the cunning described in this utility model is straight-through pipe fitting, bend pipe tools, multi-way pipe fitting, different
One kind in the pipe fitting of footpath.
Compared with prior art, the beneficial effects of the utility model are：
This utility model can realize simplifying docking for metallic conduit and PEX pipelines, and junction is reliable and stable, and installs behaviour
Make simply, shock resistance is strong, nothing is released, drainage, good seal performance.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to technical scheme described herein.
Embodiment 1：A kind of sliding tight pipe fitting, including pipe fitting body 1, the tight cutting ferrule 2 of cunning, the pipe fitting body 1 includes welding ends
With sliding tight end, the surface that the cunning is tightly held is provided with the projection 7 of some annulars, the groove 6 constituted between adjacent projection 7, institute
State boss structure 3 is provided between welding ends and sliding tight end；The tight cutting ferrule 2 of the cunning includes cutting ferrule groove 4, in the tight cutting ferrule 2 of cunning
Open interior is sequentially provided with slope 8, skewed slot 5.
Embodiment 2：A kind of sliding tight pipe fitting, including pipe fitting body 1, the tight cutting ferrule 2 of cunning, the pipe fitting body 1 includes welding ends
Tightly hold with sliding, the outer surface that the cunning is tightly held is provided with the groove 6 that some annular protrusions 7 and adjacent protrusion 7 are constituted, the welding
Boss structure 3 is provided between end and sliding tight end；The tight cutting ferrule 2 of the cunning includes sliding sleeve groove 4, in the opening of the tight cutting ferrule 2 of cunning
Portion is sequentially provided with slope 8, skewed slot 5.The pipe fitting body 1 and the tight cutting ferrule 2 of cunning are metal material.Raised 7 quantity is 4
Individual.Raised 7 cross sectional shape is trapezoidal.The quantity of the skewed slot 5 is 2.Height and cunning that the boss structure 3 protrudes
The cup depth of set groove 4 is equal.The cutting ferrule groove 4 is slided to the distance between 8 bevel end of slope length more than pipe fitting body 1
The length at tight end.1 welding ends of pipe fitting body is welded with metallic conduit, and sliding tight end is connected with PEX pipelines.
Embodiment 3：A kind of tight pipe fitting of cunning, the tight pipe fitting of the cunning is straight-through pipe fitting, bend pipe tools, multi-way pipe fitting, reduced pipe
One kind in part.The structure of remainder is identical with the structure in embodiment 1 or 2.
In view of above-mentioned technical proposal, when using, by tight for cunning cutting ferrule 2 is placed on PEX pipes, and cunning is tight for this utility model
Cutting ferrule 2 will be easy to follow-up flaring tool to carry out the enlarging of PEX pipes away from the port of PEX pipes.Then using flaring tool to this
PEX tubing carries out cold enlarging, and the size of cold expansion port can just be set to pipe fitting body 1 and slide tight end, and enlarging is fully-inserted after finishing
Slide on tight end to pipe fitting body 1, then realize extruding by clamping boss structure 3 and cutting ferrule groove 4 using special installation tool
Pipe fitting body 1 and the tight cutting ferrule 2 of cunning, until the tight cutting ferrule 2 of cunning is completely attached to the root of 1 connecting portion of pipe fitting body realizes reliable company
Connect.
Due to being provided with the groove 6 of some raised 7 and the composition of adjacent protrusion 7, groove 6 and the tight cutting ferrule 2 of cunning on pipe fitting body 1
Between be PEX tubing, which can realize sealing effectiveness well, reduce the use of Seal Kit.Section is convex for trapezium structure
Play 7, preferably right-angled trapezium, as the projection 7 is hypotenuse during clamping, is right-angle side structure after clamping, energy
Pipe fitting after being enough more effectively prevented from connecting departs from, and increases fastness.Described two skewed slots 5 coordinate with raised 7, can be more preferable
Realize anti-drop function.The height that the boss structure 3 protrudes is equal with the cup depth of connecting tube groove 4, and this is designed to
So that sliding clamping tool is preferably used cooperatively therewith, increase adaptability of the present utility model.The tight cutting ferrule 2 of cunning is additionally provided with prolongation
Section, can be easy to protect joint area without damage.The engaging PEX tubing after enlarging can be easy in slope 8, skewed slot 5.
