DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0019] Referring to Figs. 1-3 A combined automobile gasket, comprising a flexible washer 1 and two rigid washers 2, the surface of the flexible washer 1 is provided with a first through hole 3, the surface of the rigid washer 2 is provided with a second through hole 4 matched with the first through hole 3, the surface of the flexible washer 1 is annularly provided with a plurality of first positioning blocks 5, the surface of the rigid washer 2 is annularly provided with a plurality of positioning through holes 6 corresponding to the first positioning blocks 5 one by one, the inner walls of the plurality of positioning through holes 6 are all provided with flexible edges 7, the first positioning blocks 5 extend into the flexible edges 7, the outer edges of the upper and lower surfaces of the flexible washer 1 are both annularly provided with first blocking edges 8, and the rigid washer 2 projects out of the first blocking edges 8.

[0020] The upper and lower surfaces of the flexible washer 1 are both provided with a plurality of anti -slip grains 9. The plurality of anti -slip grains 9 play the role of anti -slip.

[0021] The inner wall of the two first retaining edges 8 is provided with a plurality of second positioning blocks 10, and the surface of the two rigid gaskets 2 is annularly provided with a plurality of notches 11 corresponding to the second positioning blocks 10 and matched with the second positioning blocks 10, and the second positioning blocks 10 extend into the notches 11. Through the arrangement of the second positioning blocks 10 and the notches 11, the two rigid gaskets 2 and the flexible gasket 1 can be more closely connected.

[0022] The upper and lower surfaces of the flexible gasket 1 are annularly provided with second retaining edges 12 at the inner edges, and the second retaining edges 12 play a sealing role. Through the second retaining edges 12, the flexible gasket 1 can be elastically clamped on the surface of the mounting part, so that the overall structure is not easy to shake and fall off. The rigid gasket 2 protrudes from the second retaining edge 12, so that the second retaining edge 12 does not affect the screwing of the nut, and the second retaining edge 12 is prevented from being damaged.

[0023] The surface of the two rigid gaskets 2 away from the flexible gasket 1 is annularly provided with a plurality of anti-skid ribs 13. The plurality of anti-skid ribs 13 can increase the strength of the rigid gasket 2 and also play an anti-skid role.

[0024] The side surfaces of the plurality of first positioning blocks 5 are arc-shaped. The arc-shaped structure is relatively smooth, so that the first positioning blocks 5 are not easy to be torn.

[0025] Through the extension of the first positioning blocks 5 into the positioning through holes 6, the two rigid gaskets 2 and the flexible gasket 1 can be quickly positioned. Since the inner walls of the plurality of positioning through holes 6 are provided with flexible edges 7, the flexible edges 7 are not easy to scratch the first positioning blocks 5, the rigid gasket 2 is prevented from scratching the flexible gasket 1, and the automobile gasket is prevented from being damaged. Through the clamping of the first positioning blocks 5 and the positioning through holes 6, the rigid gasket 2 and the flexible gasket 1 can be quickly positioned. During the installation and screwing, the flexible gasket 1 is not easy to be displaced. During the installation, the external force directly acts on the surface of the rigid gasket 2, and the two rigid gaskets 2 clamp the flexible gasket 1, so that the flexible gasket 1 inside is not easy to be abraded and damaged.

[0026] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
