[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-5 In an embodiment of the utility model, a hardware riveted part fixed by a riveting structure includes a riveting sheet 10 and a fixing sheet 20 arranged on the riveting sheet 10. The riveting sheet 10 is made of a material that can be drawn, and the selected material can be made of a material that has a breaking pull-out force greater than 25N for riveting, such as a copper sheet. The fixing sheet 20 is determined according to the material properties required for the hardware riveted part. The technical solution preferably takes a fixing sheet 20 made of stainless steel as an example; at least one riveting through hole 21 is opened on the fixing sheet 20. Specifically, when there is one riveting through hole 21 on the fixing sheet 20, the riveting through hole 21 is a special-shaped hole structure, and when there are at least two riveting through holes 21 on the fixing sheet 20, the riveting through hole 21 is a round hole structure; its main function is to firmly fix the fixing sheet 20 on the riveting The number and shape of the riveted through holes 21 are set on the sheet 10 for the purpose; the opening area of ​​one end of the riveted through hole 21 is larger than the opening area of ​​the other end of the riveted through hole 21. Specifically, the opening areas at both ends of the riveted through hole 21 are different in size so that the inner wall of the riveted through hole 21 can be set as an inclined surface or a curved surface, and when the inner wall of the riveted through hole 21 is, the curved surface can be an inner concave curved surface or an outer convex curved surface, which is set according to product requirements; a riveted convex 11 passing through the riveted through hole 21 is punched out on the riveted sheet 10, and the riveted convex 11 passes through the fixed sheet 20 along the end with a smaller opening area of ​​the riveted through hole 21, and a riveted portion 12 filled in the riveted through hole 21 is riveted on the riveted convex 11. The riveted portion 12 fixes the fixed sheet 20 to the riveted sheet 10 by pressing the inner wall of the riveted through hole 21.

[0024] In the above technical scheme, by utilizing the different opening areas of the two ends of the riveting through hole 21, the punched riveting convex bulge 11 is passed through and fixed along the end with the smaller opening area of ​​the riveting through hole 21, and then the riveting convex bulge 11 is riveted to form a riveting portion 12 that is filled into the riveting through hole 21 in a certain direction. In the actual production process, the riveting sheet 10 with a set size is first fixed on a punching machine with a set mold to punch out the riveting convex bulge 11, and then the fixing sheet 20 is placed along the riveting convex bulge 11. The riveting convex bulge 11 can play a role in positioning the fixing sheet 20. The riveted convex bump 11 is then punched by a punch press so that the riveted convex bump 11 is riveted in the riveted through hole 21 to form a riveted portion 12. The riveted through hole 21 has different opening areas at both ends, so that its inner wall will not fall out of the riveted portion 12 after being riveted. In this way, the assembly efficiency of the riveted sheet 10 and the fixing sheet 20 can be improved, and the riveted sheet 10 and the fixing sheet 20 do not need to be fixedly connected or set with other complex structures, nor do they need to be connected by screws or other connecting structures, nor do they need to be welded or other operations.
