Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a snap-fit flange with high sealing performance comprises a male head and a female head, wherein the male head comprises a male head metal layer 1, and the male head metal layer 1 is in a circular ring shape; a male rubber layer 2 is arranged on one side of the male metal layer 1, the male rubber layer 2 is annular, and the diameter of the male rubber layer 2 is smaller than that of the male metal layer 1; an outer-layer buckle 3 is welded on the outer side of the male metal layer 1, and a cylindrical bulge is welded on the inner side of the outer-layer buckle 3; an inner buckle 4 is welded on the inner side of the male metal layer 1, and a triangular bulge is welded on the outer side of the inner buckle 4; the female head comprises a female head metal layer 5, a female head rubber layer 6 is arranged on one side, close to the male head, of the female head metal layer 5, the diameter of the female head rubber layer 6 is smaller than that of the female head metal layer 5, and an outer layer slideway 7 is arranged on the outer side of the female head metal layer 5; an inner layer slideway 8 is arranged on the inner side of the female metal layer 5; the number of the outer layer buckles 3 and the number of the inner layer buckles 4 are four, and the outer layer buckles and the inner layer buckles are uniformly distributed on the male metal layer 1; the outer layer slide way 7 and the inner layer slide way 8 are Z-shaped and have the same length; one end of the inner layer slideway 8, which is close to the female metal layer 5, is connected with an inner layer surrounding slideway 9, the inner layer surrounding slideway 9 is positioned inside the female metal layer 5, the inner layer surrounding slideway 9 is annular, and the shape and the size of the cross section of the inner layer surrounding slideway 9 are the same as the triangular bulges of the inner layer buckle 4; the lengths of the outer layer slide way 7 and the inner layer slide way 8 are respectively the same as the lengths of the outer layer buckle 3 and the inner layer buckle 4.
