Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutual combination；Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is elaborated.
Reference picture 1,2,3：
The utility model proposes a kind of PVC water pipes for automobile, including body 1, sealing, body 1 has first
End and the second end；Sealing includes seal pipe 2, bandage 3, connect band 4, and one end of seal pipe 2 is connected with the first end of body 1,
The other end of seal pipe 2 extends to the direction away from body 1, and the inner circumferential surface stepped of seal pipe 2 is set, from body 1
First end to its second end, the internal diameter of seal pipe 2 is gradually reduced；Bandage 3 is looped around in seal pipe 2, and bandage 3 is provided with multiple
Holding section, length direction of multiple holding sections along bandage 3 is sequentially distributed；The two ends of connect band 4 are equipped with to be engaged with holding section
Snap fit portion.
In the present embodiment, seal pipe 2 is provided with multiple convex areas 201 and multiple depressed areas 202, multiple Hes of convex area 201
Multiple depressed areas 202 are spaced apart；Convex area 201 includes the radius of the different circular arc of multistage radius and the circular arc closer to top
It is bigger；Depressed area 202 includes the different circular arc of multistage radius and the radius of the circular arc closer to bottom is bigger；When in use, water
Pipe can be pullled, distorted, by setting multiple convex areas 201, depressed area 202, when can effectively disperse axial stretching
Bending stress, and the incremental deformation in arc surface unit area can be reduced, improve water pipe service life.
In the present embodiment, holding section is the through hole 5 through the both sides of bandage 3；Snap fit portion is connecting pole 6；There is provided a kind of
