[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below in connection with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the utility model protection.

[0018] As Figures 1-3 shown, the utility model discloses a sealed self -punching rivet nut, the sealed self -punching rivet nut includes nut main part 1 and the rivet tongue 2 of setting in one side end face of nut main part 1, the nut main part 1 is provided with screw hole 3, the rivet tongue 2 is annular, the sealed self -punching rivet nut still includes sealed baffle 4, and the sealed baffle 4 sets up in screw hole 3 and is close to one end of rivet tongue 2.

[0019] In the embodiment, a sealed self-punching rivet nut is disclosed, which is provided with a rivet tongue 2 on one end face of a nut body 1, the rivet tongue 2 is designed as a ring, a threaded hole 3 is arranged in the center of the nut body 1 for mounting other components, when the rivet nut is installed, one side of the rivet tongue 2 is abutted against the surface of the sheet metal to be riveted by using punching, the rivet tongue 2 is pressed into the sheet metal by applying punching, the sheet metal is plastically deformed when the rivet tongue 2 is pressed in to realize fixation, a sealing partition plate 4 is arranged in the inside of the threaded hole 3 in the center of the rivet nut, the sealing partition plate 4 is close to one side of the rivet tongue 2, the sheet metal is plastically deformed under the action of the rivet tongue 2 and gathers to the center to form a sealed space with the sealing partition plate 4, the sealing partition plate 4 protects the center bottom of the rivet nut, thereby avoiding aging and even rust caused by external environment, and improving the durability of the rivet nut.
