Sealing structure of wedge-shaped blocking cover

Abstract

The invention relates to a sealing structure of a wedge-shaped blocking cap, which comprises a pit and a cap. The cap is a bowl-shaped structure, and the cap is pressed into the pit. The opening of the cap faces upward, and the cap The bottom end of the cover is sealed in the pit; the outer wall of the blocking cover is an interference fit with the pit; the bottom surface of the blocking cover is a tapered surface, and the two ends of the bottom surface are in close contact with the two ends of the pit ; The outer wall and the bottom surface of the blocking cover are transitioned through a circular arc; the beneficial effects of the present invention are: 1. Increase the sealing contact area between metals; 2. Compact structure, no extra space, can be used for structural Compact metal parts are sealed; 3. No extra riveting points are required, which does not affect the appearance.

Description

technical field [0001] The invention belongs to the technical field of sealing structures, in particular to a sealing structure of a wedge-shaped blocking cap. Background technique [0002] The sealing structure of the existing wedge-shaped blocking cap uses a convex-shaped blocking cap to be pressed into the pit that needs to be sealed; the metal area around the cap needs to be riveted and deformed; the convex-shaped cap is fixed on the pit that needs to be sealed with riveting points Li (if attached figure 1 As shown); the disadvantages are: the sealing contact area between the metals is small; there needs to be a space position above the convex blocking cover that is much larger than the diameter of the outer circle of the blocking cover; it needs to be riveted and deformed, and the appearance has riveting points, which affects the appearance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and p...
