Description
Technical field
The utility model relates to a kind of interconnection technique of pipe, especially relates to a kind of cement pump truck curvedThe syndeton of pipe.
Background technology
The connection of existing pipe is to complete with the connector of connector by two ends, pipeBe connected to the two ends of connector, because the middle part of connector is a connector with cavity volume, thisSample, not only increased the manufacturing cost of connector, and, the fluid connector of must flowing throughIn cavity volume, because the structure of cavity volume is different with the structure of tube cavity, fluid enters connector from pipeCavity volume in time, foul is easily gathered in some place, dead angle in cavity volume, time one is long, theseThe easy contaminated-fluid of foul. On the other hand, because cement pump truck bend pipe is after connecting, institute's energyThe stress bearing can reduce greatly, and can not adapt to the needs of frequent dismounting.
Utility model content
Goal of the invention of the present utility model is to provide a kind of simple in structure, low cost of manufacture, noEasily gather the syndeton of the cement pump truck bend pipe of the large and easy disassembly of booty, bonding strength.The technical scheme that realizes above-mentioned purpose is as follows:
A syndeton for cement pump truck bend pipe, comprises the pipe joint of axle center hollow, pipe jointAxle center socket inner tube, the length of inner tube is longer than the length of pipe joint, in pipe joint and inner tube, overlapsConnect block, it is characterized in that: the outer wall of inner tube stretches out and forms a bulge loop, wherein corresponding protrudingRing position place, be provided with groove one at pipe joint inwall, groove one has a sidewall, inner tubeNever, in one end Inserting Tube joint of sidewall, bulge loop is contained in groove one; Its further groove oneBetween sidewall and corresponding bulge loop sidewall, sealing ring is installed, simultaneously bulge loop another side sidewall and blockBetween inwall, place successively sealing ring and pad, described pad next-door neighbour block inwall;
Wherein on pipe joint, be also socketed Anti-slip cover, the end of described Anti-slip cover and the end of block next-door neighbour,And the end of Anti-slip cover is provided with groove two, in the insertion groove two of the end adaptation of block;
Wherein away from groove two ends, on pipe joint, be also socketed anticreep block, described anticreep block is with anti-Sliding sleeve next-door neighbour, anticreep block and block are fixed inner tube and pipe joint.
Preferably, corresponding position, Anti-slip cover position, slip teeth groove is set on pipe joint outer wall, andThe tooth coordinating with anti-skidding teeth groove is set on Anti-slip cover, and what Anti-slip cover slided is fastened on anti-skidding teeth grooveOn.
Preferably, anticreep block is threaded connection with pipe joint.
Preferably, pipe joint is connected with block by screw thread with inner tube.
Preferably, groove one is threaded with bulge loop.
Preferably, described inner tube is split-type structural, and inner tube is radially cut shape open from the middle part of bulge loopBecome two joint half inner tubes.
The utility model is simple in structure, easy accessibility, and it is firm to connect, and is not easy to get loose.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In figure, the syndeton of cement pump truck bend pipe, comprises the pipe joint 1 of axle center hollow, pipeThe axle center socket inner tube 2 of joint 1, the length of inner tube 2 is longer than the length of pipe joint 1, and pipe connects1 and inner tube 2 on socket block 3, inner tube 2 is through block 3, inner tube 2 is logical with block 3Crossing is threaded is arranged on pipe joint 1, and the outer wall of inner tube 2 stretches out and forms a bulge loop 4,Wherein corresponding bulge loop 4 positions, be provided with groove 1 at pipe joint 1 inwall, groove 1Have a sidewall 6, inner tube 2 is never in one end Inserting Tube joint 1 of sidewall, bulge loop 4Be contained in groove 1, and groove 1 is threaded with bulge loop 4; Its further groove 1Between sidewall 6 and corresponding bulge loop 4 sidewalls, sealing ring 7 is installed, simultaneously bulge loop 4 another side sidesBetween wall and block 3 inwalls, place successively sealing ring 7 and pad 8, described pad 8 next-door neighbour's lidsCap 3 inwalls; Wherein on pipe joint 1, be also socketed Anti-slip cover 9, the end of described Anti-slip cover 9 withBlock 3 end next-door neighbour, and the end of Anti-slip cover 9 is provided with groove 2 10, block 3In the insertion groove 2 10 of end 11 adaptations, so connecting can be more firm.
Wherein away from groove 2 10 ends (be close to Anti-slip cover 9 do not arrange groove two one end),On pipe joint 1, be also socketed anticreep block 12, described anticreep block 12 is close to Anti-slip cover 9,Anticreep block 12 and block 3 are fixing with pipe joint 1 by inner tube 2, to prevent Anti-slip cover 9 pinesAfter moving, deviate from, preferably anticreep block is threaded connection with pipe joint, can dismantle easily.
