The stage casing of described core pipe is provided with described external lock control sheath and snaps in fixing annular groove therein.
Plastic composite pipe pipe jointing can be coiled, it is characterised in that: include that stage casing is provided with the core pipe in tool card face；?
The lateral surface of this core pipe side is provided with step, is fixed with external lock control sheath on described step so that described core pipe and institute
State formation grafting between external lock control sheath and can coil the cylinder ring of plastic composite pipe；Opposite side at this core pipe is connection bobbin；Its
In,
The end of described external lock control sheath is shunk in the end of described core pipe；
It is provided with closure gasket groove on the inwall of the external lock control sheath in described cylinder ring；
It is provided with some pawl mechanisms on the inwall of the external lock control sheath in described cylinder ring；

Can coil described in Gou Chenging in the structure of plastic composite pipe pipe jointing, the connection bobbin of described core pipe obtains end and sets
It is equipped with the bulge loop mechanism for overlapping acting flange.
One provided by the utility model can coil plastic composite pipe pipe jointing compared with prior art, have with
Lower advantage: one, owing to this hose coupling uses, be inserted into by one end can be in coiling plastic composite pipe in plastic pipe layer
Metallic connects core pipe and is fixed with the steel sheath composition being structure as a whole therewith on this metallic connection core pipe, therefore has
There is attachment structure simple and connect the feature of good sealing effect；Its two, owing to this jointing includes can realizing and flange etc.
The metallic that parts connect connects core pipe, therefore, it is possible to realize between tube and tube, pipe is connected with multiple between flange.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation coiling plastic composite pipe pipe jointing；
Fig. 2 is the structural representation that the second can coil plastic composite pipe pipe jointing.
Detailed description of the invention
Below in conjunction with the accompanying drawings the structure of a kind of pipe jointing that this utility model provides is described in further details.
It is illustrated in figure 1 the structural representation of the coiled plastic composite pipe pipe jointing that this utility model provides.Structure
The structure becoming this pipe jointing includes that stage casing is provided with tool card face 1, left and right sides lateral surface is provided with the core of step 21,22
Pipe 3, respectively by screw socket 4(or welding on the step of above-mentioned both sides) connect and have external lock control sheath 51,52 so that core pipe with
Form grafting between external lock control sheath and can coil the cylinder ring 71,72 of plastic composite pipe 61,62.
Even if the used time, directly can coil plastic composite pipe 61,62 at two ends and be inserted in a ring 71,72, then by the draw
External lock control sheath 51,52 is locked by mechanism.
