Detailed Description

The following detailed description and technical contents of the present invention are described with reference to the drawings, but the drawings are only provided for reference and illustration, and are not intended to limit the present invention.

As shown in fig. 1 to 5, the present invention provides a fastener structure for riveting an object to be riveted, wherein the object to be riveted has a plate 900, the plate 900 is provided with a through hole 91 (see fig. 4), and the through hole 91 has an inner periphery 911 (see fig. 5). The utility model discloses fastener structure 100 can correspond perforation 91 riveting in plate body 900, the utility model discloses fastener structure 100 includes: a body 1, a tray 2 and a fastening head 3.

The body 1 may be any shape, and in the embodiment, a cylinder is taken as an example for illustration. The body 1 has one end face 11 and the other end face 12 opposite to each other. The body 1 further has a mating hole 13, and the mating hole 13 is recessed from the other end surface 12 of the body 1 toward the end surface 11. The docking hole 13 may be a screw hole, but not limited thereto.

The tray body 2 is thinly embossed from the end surface 11 so that the tray body 2 can have an embossed thickness T2 (see fig. 6) by the thin embossing.

The fastening head 3 comprises a head 31 and a neck 32, the neck 32 being connected between the head 31 and the disc 2. And a necking space S (shown in fig. 3 and 5) is formed among the head 31, the neck 32 and the tray body 2.

As shown in fig. 5, 6 and 7, when the fastening head 3 of the fastening device structure 100 of the present invention is inserted into the corresponding through hole 91 from the inner surface 9a of the plate 900 toward the outer surface 9b and is simultaneously riveted, the inner surface 9a of the plate 900 is deformed by the insertion of the plate 2 with the relief thickness T2, the deformed portion 912 of the plate 900 is filled into the necking space S to be engaged and fixed with the fastening head 3, and the head 31 is exposed from the outer surface 9b of the plate 900.

The utility model discloses produced effect of fastener structure 100: because the volume sum of the fastening head 3 and the disc body 2 does not increase the volume compared with the existing rivet head, even is smaller than the volume of the existing rivet head, and only the thin embossed disc body 2 is embedded into the plate body 900, the degree of the plate body 900 deformed by extrusion is reduced, and the disc body 2 is only embedded into the inner surface 9a of the plate body 900, so that the part deformed by extrusion only appears on the inner surface 9a, and the outer surface 9b of the plate body 900 can be kept flat without soil supplement. Furthermore, since the deformed portion 912 of the plate 900 is filled into the necking space S, the fastener structure 100 of the present invention can be firmly fastened to the plate 900, and is not prone to falling off. Three, owing to utilize deformation portion 912 to block in necking down space S and guarantee firmly fixedly, consequently can reduce the bore of perforating 91 and head 31 to still littleer than current perforation and current rivet, and then let the utility model discloses the riveting point of fastener structure 100 after the riveting can become very little, so can not see the riveting point and also need not the patch through grinding a little. Thus, the fastener structure 100 of the present invention can reduce the manufacturing cost and shorten the operation time.

It should be noted that, as shown in fig. 5, 6 and 7, when riveting, the fastening head 3 is correspondingly positioned inside the inner periphery 911 of the through hole 91, and then the body 1 is riveted from the other end surface 12 toward the one end surface 11, at this time, the plate body 2 will press the inner surface 9a of the plate body 900 by the relief thickness T2, and the deformed portion 912 of the plate body 900 deformed by the pressing will move from the inner periphery 911 of the through hole 91 toward the center of the through hole 91, and further fill the necked space S of the fastener structure 100 of the present invention.

Preferably, as shown in fig. 3 and 5, the outer diameter of the head 31 is substantially equal to the inner diameter of the through hole 91, the outer diameter of the head 31 is smaller than the outer diameter of the tray body 2, and the outer diameter of the neck 32 is smaller than the outer diameter of the head 31, so that a necking space S can be collectively formed between the head 31, the neck 32 and the tray body 2. As shown in fig. 6 and 7, the sum of the embossed thickness T2 of the plate 2 and the height (not labeled) of the fastening head 3 defines a protrusion length L, which is substantially equal to the plate thickness T1 of the plate 900, and may be slightly greater than the plate thickness T1 and slightly protruded from the outer surface 9b as shown in the figure. It must be noted that the projecting length L includes the relief thickness T2 of the disk 2, the height of the neck 32 and the height of the head 31.

As shown in fig. 3 to 7, the body 1 defines a riveting direction D (see fig. 4), the body 1 is formed with the end surface 11 along the riveting direction D, the tray body 2 is thinly embossed from the end surface 11 along the riveting direction D, and the neck portion 32 is connected between the head portion 32 and the tray body 2 along the riveting direction D. In the present embodiment, the plate body 2 and the fastening head 3 connected in the manner described above together form an I-shape (see fig. 5).

As shown in fig. 3 to 7, the outer edge of the disc body 2 may also have a plurality of teeth 21, so when the fastener structure 100 of the present invention is inserted and riveted with the fastening head 3 corresponding to the through hole 91 in the riveting direction D, the inner surface 9a of the plate body 900 will be deformed because the disc body 2 and the plurality of teeth 21 are embedded with the relief thickness T2, so that the deformed portion 912 of the plate body 900 will partially engage with the plurality of teeth 21 to prevent the disc body 2 (or the body 1) from rotating, and the other portion will be filled into the necking space S to be engaged with the fastening head 3, and the head 31 will be exposed from the outer surface 9b of the plate body 900.

The disk 2 is in thin relief from the end surface 11 along the riveting direction D and has a disk surface 22 (see fig. 3 and 4), the disk surface 22 is perpendicular to the riveting direction D, and the teeth 21 are protruded from the center of the disk 2 along the disk surface 22 toward the outer edge of the disk 2, so that the disk 2 is like a toothed disk.

To sum up, the fastener structure 100 of the present invention can achieve the expected purpose of use, and can solve the drawbacks of the background art, and completely meet the requirements of the new patent application.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all changes in equivalent structures made by the contents of the specification and drawings are intended to be embraced by the scope of the present invention.
