It is two connection ends of water pipe to split most places, therefore connected mode of the prior art also has deficiency.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of connector of use upper and lower conduit interface can
The tight connection of upper and lower pipeline is realized, without using complicated attachment structure, it is impossible to which outer wrap fluid sealant, service life is more
Long.
The utility model is achieved through the following technical solutions：A kind of PVC drain pipe pipe connecting, including upper end
First pipeline, the second pipe of lower end and the connector for connecting the first pipeline and second pipe, the first pipeline bottom
Portion openend is provided with First terrace, and second step face is provided with the connector, and connector is put into from top to bottom
In first drainage channel of one pipeline, First terrace is contacted with second step face, between First terrace and second step face
Sealed by sealing structure, the bottom of connector is inserted in the second drainage channel that second pipe upper end opens up, and is led to
The 3rd step surface that the self-locking structure and second pipe upper end open end for crossing connector bottom are set completes fixed locking.
Preferably, the sealing structure includes the first snap ring being arranged on connector second step face, the first snap ring
A draw-in groove is formed between connector, the second snap ring being arranged on First terrace is just set to draw-in groove, the second snap ring card
Enter in draw-in groove, sealing ring is provided between the second snap ring and draw-in groove.
Preferably, the self-locking structure includes the more than one groove being arranged on connector, it is respectively provided with groove
One spring, spring outwards end sets a limited block, and the limited block is provided with an inclined plane, and the inclined plane is arranged at groove outside
Face, the inclined-plane of inclined plane is just to the upper end open end of second pipe.
Preferably, connected by Screw assembly between the lower end port of export of the connector and the first pipeline, connector
Lower end stretches out in the first pipeline and is inserted in second pipe inner section for smooth section.
Preferably, the upper surface of the connector is provided with a circle arc diversion section.
The beneficial effects of the utility model are：The connector of upper and lower conduit interface of the present utility model can be realized up and down
The tight connection of pipeline, without using complicated attachment structure, it is impossible to which outer wrap fluid sealant, service life is more long.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Coding in figure is respectively：1 is arc diversion section, and 2 is sealing ring, and 3 is the first snap ring, and 4 is the second snap ring, and 5 are
Limited block, 6 is spring, and 7 is second pipe, and 8 is connector, and 9 is the first pipeline.
Specific embodiment
As shown in figure 1, this PVC drain pipe pipe connecting, including upper end the first pipeline 9, lower end second pipe 7 and use
In the connector 8 for connecting the first pipeline 9 and second pipe 7, the bottom open end of the first pipeline 9 is provided with first step
Face, is provided with second step face on the connector 8, connector 8 is put into the first drainage channel of the first pipeline 9 from top to bottom
Interior, First terrace is contacted with second step face, is sealed by sealing structure between First terrace and second step face, connection
The bottom of part 8 is inserted in the second drainage channel that second pipe upper end opens up, and by the self-locking of the bottom of connector 8
Structure completes fixed locking with the 3rd step surface that second pipe upper end open end is set.
In the present embodiment, sealing structure includes the first snap ring 3 being arranged on the second step face of connector 8, the first snap ring 3
A draw-in groove is formed between connector 8, the second snap ring 4 being arranged on First terrace is just set to draw-in groove, the second snap ring 4
Snap into draw-in groove, sealing ring 2 is provided between the second snap ring 4 and draw-in groove.
Self-locking structure includes the more than one groove being arranged on connector, and a spring 6, spring 6 are respectively provided with groove
Outboard end sets a limited block 5, and the limited block 5 is provided with an inclined plane, and the inclined plane is arranged at groove lateral surface, inclined plane
Inclined-plane just to the upper end open end of second pipe 7.
By the assembly connection of screw thread 10 between the lower end port of export of the pipeline 9 of connector 8 and first, the lower end of connector 8 is stretched out
In the first pipeline 9 and the inner section of second pipe 7 is inserted in for smooth section, when connector is encased in the first pipeline from top to bottom
Afterwards, smooth section, directly through the first pipeline to the lower end of the first pipeline, now rotates connector by hand first so that connector energy
Enough Screw assemblies completed with the first pipeline, the second snap ring 4 seals waterproof after snapping into draw-in groove by sealing ring, now can not
Rotated, then section of stretching out be inserted in second pipe, limited block is retracted into groove during insertion, through second pipe after limit
Position block ejection so that with the 3rd step surface clamping, complete the assembly connection of second pipe and the first pipeline.
In the present embodiment, the upper surface of connector is provided with a circle arc diversion section 1, is realized by the arc diversion section 1
