When rivet 20 is fixed on the substrate 10, by tool, rivet fixed hole 11 is passed in the lower end of rivet 20, then the convex edge 22 of rivet 20 is made to abut on the substrate 10, make screw thread 23 extrude the edge of rivet fixed hole 11 and prevent rivet 20 from rotating, and screw thread 23 can make when extruding the edge of rivet fixed hole 11 in the part embedding groove 24 at rivet fixed hole 11 edge and be fixed on the substrate 10 by rivet 20.
But the means of fixation of existing rivet 20, stable for rivet 20 can be fixed on the substrate 10 when the thickness of substrate 10 is larger, but along with electronic product is to the future development of ultrathin, reduce the thickness of substrate 10 accordingly, thus cause substrate 10 not have enough thickness to embed in groove 24 to make the part at rivet fixed hole 11 edge, therefore the fixed structure of existing rivet can cause the inclination of rivet 20, and then causes the fixing instability of rivet 20.
Model utility content
The purpose of this utility model is the fixed structure providing a kind of rivet, is intended to solve rivet and fixes unstable technical problem.
In order to realize the purpose of this utility model, the utility model provides a kind of fixed structure of rivet, comprising:
Substrate, substrate offers rivet fixed hole, and this substrate is vertically extended with flange at the edge of rivet fixed hole;
Rivet, rivet has riveting post, rivet fixed hole and the flange of substrate are passed in one end of riveting post, the other end of this riveting post extends the convex edge be connected on substrate, riveting post offers the groove around this riveting post in the below of convex edge, riveting post is provided with screw thread between groove and convex edge, and screw thread compresses the hole wall of fixed hole and makes a part for the hole wall of fixed hole embed in groove;
Fixed cover, fixed cover has ringwise engagement portion, being set on flange of this engagement portion and flange interference fit.
As the improvement of the fixed structure of the above-mentioned rivet of the utility model, described engagement portion and flange interference fit and make a part for flange embed in groove further.
As the improvement of the fixed structure of the above-mentioned rivet of the utility model, described fixed cover is also provided with rivet belled part in one end of engagement portion, and rivet belled part is set on one end passing rivet fixed hole and flange of riveting post.
Correspondingly, the utility model also provides a kind of fixed structure of rivet, comprising:
Substrate, substrate offers rivet fixed hole, and this substrate is vertically extended with flange at the edge of rivet fixed hole;
Rivet, rivet has riveting post, rivet fixed hole and the flange of substrate are passed in one end of riveting post, the other end of this riveting post extends the convex edge be connected on substrate, riveting post offers the groove around this riveting post in the below of convex edge, riveting post is provided with screw thread between groove and convex edge, and screw thread compresses flange and makes a part for flange embed in groove;
Fixed cover, fixed cover has ringwise engagement portion, being set on flange of this engagement portion and flange interference fit.
Because the fixed structure of the utility model rivet is by arranging flange to be set on rivet at the edge of rivet fixed hole, and by the flange interference fit of the engagement portion of fixed cover and substrate is made flange fixing rivet, thus can be stable rivet be fixed on substrate, and then rivet deflection can be prevented.

The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Below in conjunction with the drawings and specific embodiments, technological scheme described in the utility model is described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
Refer to Fig. 3, Fig. 4 and Fig. 5, there is disclosed a preferred embodiment of the fixed structure of the utility model rivet.In the present embodiment, the fixed structure of rivet comprises the fixed cover 300 of substrate 100, fixing rivet 200 on the substrate 100 and fastening rivet 200.
Substrate 100 offers rivet fixed hole 110, and this substrate 100 is when offering rivet fixed hole 110, stamps out the flange 120 extended downward vertically at the edge of rivet fixed hole 110, to make the axis of the bearing of trend chain riveting fixed hole 110 of flange 120.
Rivet 200 has riveting post 210, the radial direction of this riveting post 210 cross section of the upper end edge of riveting post 210 outwards vertically extends convex edge 220, riveting post 210 is provided with screw thread 230 in the below of convex edge 220, and riveting post 210 offers the groove 240 around this riveting post 210 in the below of screw thread 230.
Fixed cover 300 has ringwise engagement portion 310.The internal diameter of this engagement portion 310 is slightly less than flange 120 external diameter, thus can make engagement portion 310 and flange 120 interference fit.In addition, the lower end of engagement portion 310 also vertically extends the rivet belled part 320 that can be set in rivet 200 lower end.
When rivet 200 is fixed on the substrate 100, by the lower end of rivet 200 through rivet fixed hole 110 and flange 120, make the convex edge 220 of rivet 200 abut on the substrate 100, make screw thread 230 extrude the hole wall of rivet fixed hole 110 and prevent rivet 200 from rotating; Then by the lower end being set in rivet 200 of rivet belled part 320, the engagement portion 310 of fixed cover 300 and flange 120 interference fit of substrate 100 be set on flange 120, make flange fixing rivet 200 to make engagement portion 310 extrude flange 120, and engagement portion 310 can make when extruding flange 120 part for flange 120 embed further fixing rivet 200 in groove 240.
Because the fixed structure of the utility model rivet is by arranging flange 120 to be set on rivet 200 at the edge of rivet fixed hole 110, and by the engagement portion 310 of fixed cover 300 and flange 120 interference fit of substrate 100 are made flange 120 fixing rivet 200, thus can be stable by fixing for rivet 200 on the substrate 100, and then rivet deflection can be prevented.
Certainly, when the thickness of substrate 100 is less, the screw thread 230 of riveting post 210 can be made to extrude flange 120 and a part for flange 120 is embedded in groove 240.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
