Belong to fastener include metal joint and metal sleeve, described metal joint one end stretch in multiple tube inner tube with its socket connection, and
Being provided with O-ring seals between metal joint and multiple tube inwall, metal sleeve is socketed on outer pipe of composite pipe, on metal joint
Being provided with annular slot, metal sleeve termination arranges inwardly protruded bulge loop, and under external force, bulge loop mates card with annular slot
Connecing in succession, multiple tube is sealed by metal button member, and the metal joint other end can connect the buckle of another multiple tube by connector
Part.This utility model, by using above-mentioned technology, utilizes metal sleeve and metal joint to be respectively fitted over multiple tube outer wall and inwall,
Then utilize buckle machine compress metal sleeve make multiple tube by metal joint and metal sleeve clamping, by Combined type pipe clamp at both
Between, simultaneously because the existence of O-ring seals, make to be formed between metal joint and multiple tube secondary seal, by multiple tube just with gold
Belonging to fastener effectively to combine, both prevented from slipping the sealing property also ensureing joint, metal joint one end can be by even simultaneously
Fitting connects the metal button member of another root multiple tube termination, so that two multiple tubes are effectively tightly connected.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is metal joint structural representation of the present utility model.
In figure: 1-metal joint, 101-annular slot, 2-metal sleeve, 201-snap ring, 3-O shape sealing ring, 4-groove,

Detailed description of the invention
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is also
It is not limited only to this:
As depicted in figs. 1 and 2, a kind of plastic composite pipe of the present utility model and the Hermetical connecting structure of metal button member, bag
Including multiple tube 6 and metal button member, described metal button member includes that metal joint 1 and metal sleeve 2, described metal joint 1 one end are stretched
Enter in multiple tube 6 inner tube with its socket connection, and metal joint 1 stretches into the middle part of multiple tube 6 one end and is provided with groove 4, on groove 4
Being provided with O-ring seals 3, seal, be provided with O-ring seals 3 between multiple tube 6 inwall, metal sleeve 2 is socketed in
On multiple tube 6 outer tube, metal joint 1 is provided with annular slot 101, and metal sleeve 2 termination arranges inwardly protruded bulge loop 201,
Under external force, bulge loop 201 mates clamping with annular slot 101 and is connected, and multiple tube 6 is sealed by metal button member, metal joint 1
