Detailed Description

The present invention will be described in detail below with reference to the drawings, but it should be emphasized that the following embodiments are merely illustrative and are not intended to limit the scope and application of the present invention.

Referring to fig. 1 to 4, the toothed gasket of the present invention includes a gasket body 1 and a plurality of tooth blocks 2 disposed around the gasket body 1.

Referring to fig. 1, in the present embodiment, the gasket body 1 is square, and in other embodiments, the gasket body 1 is circular or triangular. The gasket body 1 includes an upper surface 11, a lower surface (not indicated) parallel to the upper surface 11, a gasket side surface 13, and an extension plate 14 formed to extend horizontally outward from the periphery of the lower surface. The gasket side 13 is perpendicular to the extension plate 14 and encloses an open space 15, and the plurality of tooth blocks 2 are arranged in parallel in the open space 15 at equal intervals. Referring to fig. 3 and 4, a corner of the extension plate 14 is cut to form a triangular portion 16, and two sides of the triangular portion 16 are equal and perpendicular to each other. Furthermore, the extension plate 14 has a width k, the height of the gasket side 13 is h, and k < h < 1.2 k.
