Specifically, the plurality of tooth-shaped sealing geometric bodies are circular and concentric with the center of the annular boss.
Preferably, the edge of the upper end face of the nut body is also provided with a raised annular closed flange along the circumferential direction, a plurality of locking teeth are uniformly distributed on the flange along the circumferential direction, and the locking teeth extend along the radial direction of the flange and face the direction of the annular boss.
Further, the height of the flange is higher than the height of the toothed seal geometry.
Further, the flange is concentric with the toothed sealing geometry.
Specifically, the tooth shape of the tooth-shaped sealing geometric body is trapezoidal.
Specifically, the nut body and the annular boss are provided with internal thread holes which are communicated up and down.
The scope of the present invention is not limited to the specific combinations of the above-described features, and other embodiments in which the above-described features or their equivalents are arbitrarily combined are also intended to be encompassed. For example, the above features and the technical features (but not limited to) having similar functions disclosed in the present application are mutually replaced to form the technical solution.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages: the adoption sets up a plurality of concentric dentate sealed geometry on nut body upper portion terminal surface for waterproof rivet pressing nut can form the structure of class labyrinth with the substrate when being connected with the substrate fastening, and then can gain better water-proof effects, accords with the user demand. The waterproof pressure riveting nut has the advantages of good processing manufacturability, simple production process, simple structure and good universality, can realize the sealing and fastening between the waterproof pressure riveting nut and a base material without sealing rings, sealing glue, aluminum/copper sleeves and other auxiliary sealing pieces, and is simple to apply, efficient, energy-saving and environment-friendly. The connection is efficient and reliable.

Detailed Description
As shown in fig. 1 to 3, the waterproof clinch nut includes a nut body 1 and an annular boss 2 provided on an upper portion of the nut body 1. The nut body 1 and the annular boss 2 are provided with an internal thread hole 3 which is vertically communicated. The nut is characterized in that a plurality of protruding tooth-shaped sealing geometric bodies 4 are arranged on the end face of the upper portion of the nut body 1, and the plurality of tooth-shaped sealing geometric bodies 4 are sequentially and concentrically arranged from the periphery of the annular boss 2 outwards. The plurality of tooth-shaped sealing geometric bodies 4 are circular and concentric with the center of the annular boss 2. The tooth shape of the tooth-shaped sealing geometric body 4 is trapezoidal.
The edge of the upper end face of the nut body 1 is also provided with a raised annular closed flange 5 along the circumferential direction, a plurality of locking teeth 51 are uniformly distributed on the flange 5 along the circumferential direction, and the locking teeth 51 extend along the radial direction of the flange 5 and face the direction of the annular boss 2. The flange 5 is concentric with the toothed sealing geometry 4. The height of the flange 5 is higher than the height of the toothed sealing geometry 4.
The waterproof pressure rivet nut described in this embodiment can be used for the fastening connection between sheet metal component class spare part. The use method is as follows:
1. through holes matched with the annular bosses 2 are formed in the base material matched and fastened with the waterproof pressure riveting nut 100 through processes such as stamping and the like.
2. The annular boss 2 of the waterproof clinch nut 100 is inserted in alignment with the unthreaded hole, and the nut body 1 abuts against the surface of the substrate.
3. The waterproof pressure riveting nut is fixed on a base material in a pressure mode at the nut body 1, and the surface of the base material is deformed under pressure to form a surface matched with the tooth-shaped sealing geometric body 4 and the flange 5.
After the fastening operation, the tooth-shaped sealing geometric bodies 4 form a structure similar to labyrinth seal on the base material, so that the sealing performance of the waterproof clinch nut 100 is greatly improved, and the requirement of waterproofness can be effectively met.
Due to the arrangement of the locking teeth 51 on the flange 5, the waterproof clinch nut 100 can be prevented from rotating relative to the base material during use, and self-fastening of the nut body 1 on the base material can be realized. The nut body 1 of the base material and the waterproof clinch nut 100 can be effectively prevented from being loosened due to some reason to cause water seepage. Thus, the waterproof clinch nut 100 is efficiently and reliably connected to the substrate, and the connected assembly can withstand excellent mechanical loads such as pushing, pulling, twisting, shearing, and the like.
But also because the height of the flange 5 is higher than the height of the toothed sealing geometry 4, the water resistance is further improved.
The invention can realize connection without special tools, and has simple and efficient installation process. The connection is realized at a certain pressure and a working stroke, and the high torsion resistance and the high push-out resistance are realized.
The invention is suitable for metal plates of steel, stainless steel, copper, aluminum alloy and the like. Generally, the hardness of the waterproof clinch nut is greater than the hardness of the substrate.
The terms of orientation such as front, back, left, right, up and down are defined as the orientation of the waterproof clinch nut in normal use.
As described above, the present invention has been explained fully in accordance with the gist of the present invention, but the present invention is not limited to the above-described examples and implementation methods. A practitioner of the related art can make various changes and implementations within a range allowed by the technical idea of the present invention.
