For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Its attached drawing.
Fig. 1 is the explosive view of the present invention.
Fig. 2 is the schematic diagram of plastic telescopic pipe of the present invention and stainless steel telescoping tube water inlet end.
Fig. 3 is the schematic diagram of plastic telescopic pipe of the present invention and stainless steel telescoping tube water outlet.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, is carried out to the technical solution in inventive embodiments clear, complete
Ground describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, shall fall within the protection scope of the present invention.
Reference explanation book attached drawing, a kind of drainpipe, including plastic telescopic pipe 10 and stainless steel telescoping tube 20, the plastics are stretched
The draw is set in stainless steel telescoping tube.
Plastic telescopic pipe and the connection structure at stainless steel telescoping tube Inlet and outlet water both ends are described in detail below：
The connection structure of plastic telescopic pipe and stainless steel telescoping tube water inlet end is as follows：
Further include the first connector 30, one end of the plastic telescopic pipe is set on the first connector periphery wall, described stainless
The periphery of steel telescoping tube one end, which is arranged with, compresses snap ring 40, and in one embodiment, which is a C-shaped ring, is not one
Totally enclosed snap ring, the snap ring that compresses couple by plastic telescopic pipe, no with the first connector cooperation in plastic telescopic pipe
Rust steel telescoping tube and the first connector are fixed together.Annular convex platform 31, the annular convex platform are additionally provided on first connector
On be provided with external screw thread 32, be provided with outside first connector and coordinate the locking nut 50 couple, the compression to block with external screw thread
Ring is located at locking nut inner circumferential.The internal perisporium of the locking nut bottom is provided with bulge loop 51, and the compression snap ring is located at bulge loop
Top.
Specifically：The plastic telescopic pipe includes bellows segment 11 and the straight pipe 12 positioned at bellows upper and lower side, wherein
The end set of one straight pipe has annular flange 13, and the annular flange, which is located at, compresses snap ring upper surface and annular convex platform lower face
Between.
Further, plastic telescopic pipe and the connection structure of stainless steel telescoping tube water outlet are as follows：
Further include the second connector 60, the other end of the plastic telescopic pipe is set in the periphery of the first connector, described stainless
Steel telescoping tube other end periphery is provided with fixed ring 70, and the fixed ring joins with the second connector cooperation in plastic telescopic pipe
It connects and plastic telescopic pipe, stainless steel telescoping tube and the second connector is fixed together.It is provided with convex annular in the middle part of second connector
61 are played, the lower end of the plastic telescopic pipe is located at the upper surface of annular protrusion.The second connector periphery above annular protrusion
It is provided with and the matched seal ring of plastic telescopic pipe internal perisporium 62.
In the present invention：The perfect adaptation of stainless steel telescoping tube and plastic telescopic pipe, inner tube are plastic telescopic pipe, and outer tube is not
Become rusty steel telescoping tube；Stainless steel telescoping tube is connected with plastic telescopic pipe upper end：First connector is fastened with plastic telescopic pipe cooperation, and first
Connector and locking nut are threadedly coupled, and the inside covers a compression snap ring, when the first connector and locking nut more tighter, the inside
Compression snap ring will more hold plastic telescopic pipe and stainless steel telescoping tube；Lower end is that the second connector and plastic telescopic pipe are tight
Gu being killed with fixed ring.When telescoping tube is when stretching, inner tube plastic telescopic pipe and outer tube stainless steel telescoping tube can stretch,
