Description of the Invention: [Technical Field] The present invention relates to a riveting column and a riveting structure using the same. [Prior Art] In a conventional computer, DVD, VCD, etc. chassis structure, The chassis board is connected to other connectors such as the circuit board and usually needs to be screwed and fixed. The threaded fit method precedes the chassis plate to form a threaded bore' and is then screwed. However, the chassis of such an electronic device is generally made of a wall thickness of #父薄板, so the area of action between the screw and the chassis plate is small when the screw is used, the connection strength is not large, and the machine=appearance is easily affected. SUMMARY OF THE INVENTION In view of the above circumstances, it is necessary to provide a riveting column having a large riveting strength and an improved appearance, and a riveting structure using the riveting column. P is connected to the stalking portion of the stalking portion of the stalking bottle, and the splicing portion of the splicing portion includes a first flange and a second flange, and the first flange and the second convex portion define a receiving groove. The second flange is closer to the first flange, and the distance from the outer side of the first flange to the axis of the riveting column is less than the distance from the outer side of the first flange to the axis of the riveting column.哕 哕 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接 接The riveting portion is riveted to the PIFIA, /, and a flange of the flange in the riveting hole, and the first flange and the first portion are enclosed as a receiving groove, and the scraping material is generated when the butt joint is riveted. 200938740 is partially received in the receiving trough, the second flange is closer to the body than the first flange, and the distance from the outer side surface of the first flange to the axis of the riveting column is less than at least a portion of the two flanges From the outer side surface to the riveting (four) core line. Compared with the prior art, the riveting column body is provided with a threaded hole, which can be used for screwing with an external screw, and has a large screwing area, and has a larger screwing. Strength; and the 1st groove between the first flange and the second flange can make the scrap produced during the riveting process at least partially accommodated in the basin, avoiding riveting and embossing to ensure a better joint [Embodiment] The present invention will be described below with reference to the accompanying drawings and embodiments. The riveting column and the riveting structure using the riveting column are further described in detail. Referring to Figures 1 and 2, there is shown a preferred embodiment of the present invention, which comprises a butt joint 1〇 and riveted thereto. The riveting post 2〇. The docking member 10 can be a chassis plate having a thickness of less than or equal to 2 mm, and the hardness of the butt joint 10 is less than the hardness of the riveting and mounting. The butt joints are provided with a circular riveting hole 12, which is The rivet column 20 includes a body 22 and a rivet portion 24 connected thereto. The body 22 is a cylindrical column body having a threaded hole 221 therein. The threaded hole 221 is a through hole penetrating through the body 22 and the rivet portion 24 The rivet portion 24 includes a first flange 242 and a second flange 244. The first flange 242 is located at one end of the rivet portion 24 and is flush with the end surface, and the second flange (10) is adjacent to the body with respect to the first flange 242 1 22. The first flange includes an upper bottom surface 2421, a lower bottom surface 2422, and a side surface 2423. The upper bottom surface 2421, the lower bottom surface 7 200938740 2422 and the side surface 2423 are respectively provided with a first chamfer 2424. The second flange 244 is substantially polygonal. a columnar body including an upper bottom surface 2441 and a lower bottom surface 24 The first bottom surface 2441 and the lower bottom surface 2442 are hexagonal, and the second side chamfer 2444 is provided at the joint between the plurality of side surfaces 2443. The first flange 242 and the second flange 244 are enclosed. The groove 246. The distance from the outer side surface 2423 of the first flange 242 to the axis line 26 of the rivet column 20 is Di, and the distance from the outer side surface 2443 of the second flange 244 to the axis line 26 of the rivet column 20 is 0 D2, the docking member 10 The radius of the upper blind hole 12 is Ds'DsSDi'Dy. Further, the minimum wall thickness ratio of the rivet portion 24 is greater than the wall thickness H2 of the body 22. The thickness of the second flange 244 is the first flange 242 and the second flange 244. The distance between the two ends is T2, and the thickness of the first flange 242 is T3. , T2, T3 are related to the material of the butt joint 10 and the required joint strength. To avoid deformation of the riveting column 20 during the riveting process and the first flange 242 is squeezed during the riveting process, preferably, Τ! 2 0.25 Mm, T22 0.25mm, T32 0.3mm. It can be understood that the second flange 244 can be an asymmetrical structure, that is, as long as the distance from the outer side of the second flange 244 to the axis line 26 of the rivet 枉 20 is greater than the outer side of the first flange 242 to the rivet column The distance of the axis line 26 of 20 can form the receiving groove 246, and the riveting of the riveting column 20 and the docking member 10 is realized. As shown in FIG. 3, the riveting structure 100 uses the riveting column 20 to rive the abutting member 10. The threaded hole 221 provided in the body 22 of the riveting column 20 has a large thread length, so that the external screw has a large working area when it is coupled with the screw. , resulting in a larger thread bond. Moreover, since the distance D2 of the outer side surface 2443 of the second flange 244 to the axial line 26 of the rivet post 20 is greater than the distance Di of the outer side surface 2423 of the first convex 200938740 edge 242 to the axial line 26 of the rivet post 20, the first flange 242 and A second receiving groove 246 is defined between the second flanges 244. The scraping material 122 generated during the riveting of the riveting column 20 into the docking member 10 can be accommodated in the receiving groove 246, thereby avoiding the riveting process. The splicing of the wall of the rivet hole 12 of the abutting member 10 by the excess scrap 122 is embossed, so that the docking member 10 has a better appearance. Further, due to the first chamfer 2424 of the first flange 242 and the second chamfer 2444 of the second U flange 244, in the process of riveting the riveting post 20 into the docking member 10 using an external force, the mating piece 10 is broken. The material 122 is easier to flow into the receiving groove 246 under the guidance of the first chamfer 2424 and the second chamfer 244; 4, thereby making it easier to increase the riveting strength of the butt joint 10 and the riveting column 20 and avoid embossing. Further, since the upper bottom surface 2441 and the lower bottom surface 2442 of the second flange 244 have a hexagonal shape, the riveting post 20 can be rotated after being riveted into the docking member 10 to improve the torsion resistance after the riveting; and the second flange 244 The second chamfer 2444 of the side 2442 inter-turn joint provides a more uniform flow of debris around the second flange 244, ensuring the stability of the riveting. Further, the minimum wall thickness Hi of the rivet portion 24 is larger than the wall thickness H2 of the body 22, and the strength of the rivet portion 24 is large, so that it is easier to prevent the rivet portion 24 from being damaged during riveting. It can be understood that in the preferred embodiment of the present invention, the threaded hole 221 in the body 22 of the rivet column 20 can also be a blind hole. The upper surface 2441 and the lower bottom surface 2442 of the second flange 244 can also be octagonal, and the docking member 10 can be The rivet hole 12 can also be a through hole, and the receiving groove 246 can also accommodate only a portion of the 200938740 scrap produced when riveting. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be equivalently modified or changed in accordance with the spirit of the present invention.
