Detailed Description

The present invention will now be described in further detail with reference to the attached drawings, which are provided for purposes of illustration and not limitation.

Specific examples are given below.

The following double-sealing buckle structure comprises a buckle body 1 and a sealing plug 2;

The sealing plug 2 comprises a hollow plug body 11 and a plug disc 8. The sealing plug 2 and the buckle body 1 are mutually clamped.

The buckle body 1 comprises a top cap 3, a clamping neck 4 is arranged on the lower portion of the top cap 3, a chuck 5 is arranged on the lower portion of the clamping neck 4, an elastic sealing disc 6 is arranged on the lower portion of the chuck 5, and a buckle body 7 is arranged on the lower portion of the elastic sealing disc.

the top cap 3 has a cylindrical counterbore 10 in the center. Avoid causing buckle hood 3 to appear the sink mark because of other reasons.

The button body 7 is a cone, and the edge of the cone is wavy. The buckle body 7 is clamped with the sealing plug 2 through the convex part.

the buckle body 7 is provided with a first groove 13 and a second groove 14 which are both linear; the first grooves are shallow 13 and located on the surface of the cone, the second grooves 14 are deep, the depth of the second grooves 14 reaches more than one third of the diameter of the cone, the length of the second grooves 14 extends to the tip of the cone, the grooves of the same type are symmetrically distributed, and two grooves of the same type are distributed around the buckle body 7 in a group.
