Description
Technical field
The present invention relates to the technical field of plastic tube spigot-and-socket connecting pipe fitting.
Background technology
Vehicle is seen everywhere pipe fitting part, including metal and plastics, for plastic pipe, its connected mode is electricity mostly
The modes such as connection, clamp connection, thermal contraction connection, the flange connection of hot melt strip, are typically all attached by the way of craft,
Some connected mode intensity preferably, but connects difficult, complex process.Some connected modes are unsuitable for submersible, particularly
The connected mode heated with flame gun, it is by thinking that it is larger that operation factors are affected.During hot melt, due to not adopting centring machine
Structure, causes socket-type plastic tube uneven with the bonding strength of adapter set and deviation occurs in axle center between the two, it is impossible to ensure two
End face is mutually contradicted between person, and the intensity easily caused between socket-type plastic tube and adapter set connecting portion declines.Spigot-and-socket
Plastic tube pipe laying, because gravity is irregular, causes socket-type plastic tube to deform and ftracture with adapter set junction in sedimentation, causes
Engineering has to do over again, and has both wasted engineering material and manpower, extends the duration, increased the operating cost of engineering.
Chinese patent discloses a kind of socket-type plastic tube with adapter set centering mechanism used for carrying out hot melting（The patent No.：
CN201110303353.5）, including screw rod, swivel nut, pin, rubber cushion blocks, centering jaw, umbrella frame, umbrella frame support, connecting pin
Including structure, the end of screw rod is active with the umbrella head for being uniformly provided with umbrella frame head groove to be fixedly connected, and umbrella head is by connecting pin and umbrella frame
Active connection, screw rod is connected by screw thread with the swivel nut for being uniformly provided with umbrella frame mounting groove, and umbrella frame supports one end to pass through connecting pin
Active to be fixed in corresponding umbrella frame groove, umbrella frame supports the other end to be fixed on the umbrella frame peace that swivel nut is provided with by the way that pin is active respectively
In tankage；By pin, centering jaw is active to be fixed in the groove of umbrella frame top centering jaw groove.The mechanism reaches socket-type plastic tube
It is consistent with the axle center of adapter set, so as to the bonding strength for overcoming Electric thermal smelting belt is uneven, pipe is easily deformed and ftractures
Defect, makes socket-type plastic tube construct suitable for various environment with the socket-type plastic tube of adapter set hot-melt adhesive paste composition, carries
High project progress.But said structure has the disadvantage that：Due to needing rotary screw lead-screw to feed in centering, enter
And prop up ribs of the fan and realize the real new centering of the support of plastic pipe inner wall, the mode of the threaded adjusting is slow and inconvenient, causes centering
Efficiency is low, and then affects overall process velocity.
