Be set side by side with the inside of the pipe socket the first annular groove that is adapted with the sealing device and with the card
The second adaptable annular groove of connection device.
Preferably, the clamping apparatus includes the metallic sheath being fixed in second annular groove and is connected to the metal
Metal C-shaped ring inside set, and sawtooth is provided with the inside of the metal C-shaped ring, the metallic sheath is internally provided with the gold
Belong to the adaptable neck of C-shaped ring.
Preferably, straight mouth is provided with the pipe socket, the internal diameter of the straight mouth is outer not less than tubing body
Footpath.
Therefore, the utility model uses the PVC-O pipe socket piecing devices of said structure, and tubing socket is arranged side by side
Two annular grooves, effectively pipe socket end is formed and constrained, sound construction is reliable, and sealing is preferable, solves due to axial direction
The problem of power causes interface to take off mouth.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Embodiment
Fig. 1 is a kind of structural representation of PVC-O pipe sockets piecing devices embodiment of the present invention；Fig. 2 is the present invention one
Structural representation after the first time heating of kind PVC-O pipe socket piecing devices embodiments；Fig. 3 is a kind of PVC-O of the present invention
The partial schematic diagram of pipe socket piecing devices embodiment；Fig. 4 is a kind of PVC-O pipe sockets piecing devices embodiment of the present invention
Metallic sheath structural representation；Fig. 5 is a kind of metal C-shaped ring of PVC-O pipe sockets piecing devices embodiment of the present invention
Structural representation.As illustrated, the invention provides a kind of PVC-O pipe sockets piecing devices, including pipe socket 1 and pipeline
Socket, pipe socket 1 are connected with the pipeline socket by sealing device 3 with clamping apparatus, and the inner side of pipe socket 1 is set up in parallel
There are the first annular groove 4 being adapted with sealing device 3 and the second annular groove 5 being adapted with the clamping apparatus, the clamping
Device includes metallic sheath 6 and metal C-shaped ring 7, and tubing bellmouth form of the invention is that have two annulars side by side in pipe socket
Groove, as first annular groove and the second annular groove, rubber seal is equipped with first annular groove, is equipped with the second annular groove
Metallic sheath and metal C-shaped ring, the bellmouth of this structure, metal C-shaped ring can be formed to pipeline socket end and constrained, once tubing is by axle
To power generation displacement, the sawtooth in metal C-shaped ring can tightly block tubing, play a part of anti-pull-off.
Technical process is：When adding swollen bellmouth, using heating twice, moulding process twice, after heating for the first time, in female end
Straight mouth is processed, straight intraoral footpath is not less than the external diameter of rubber seal；After second is heated, rubber seal and metal C
Type ring is fixed on guide head, and after a double heating, tubing shrinks, and is vacuumized by the device in guide head, makes rubber seal
Circle and metal C-shaped ring are all stuck in tubing bellmouth annular groove, draw back guide head, complete process.
The clamping apparatus includes the metallic sheath 6 being fixed on the second annular groove 5 and the metal being connected to inside metallic sheath 6
C-shaped ring 7, and the inner side of metal C-shaped ring 7 is provided with sawtooth 8, metallic sheath 6 is internally provided with the adaptable neck of metal C-shaped ring 7,
Purpose is that pipeline socket end is formed to constrain, once tubing is produced displacement by axial force, the sawtooth in metal C-shaped ring can tightly block
