The existing riveting nut is generally of a full hexagonal structure, installation guiding is achieved through the hexagonal structure, a hole corresponding to the riveting nut on a sheet metal part needs to be opened into a hexagonal structure, the hexagonal hole is not prone to being opened, the direction problem needs to be considered when the riveting nut is installed, the hexagonal structure of the riveting nut is aligned with the hexagonal hole accurately, installation can be achieved, and installation and operation are inconvenient.
SUMMERY OF THE UTILITY MODEL
Prevent following the commentaries on classics effect poor to the riveting nut that exists among the prior art, the inconvenient problem of installation operation, the utility model provides a sheet metal component is with preventing following the commentaries on classics riveting nut, and it can improve and prevent following the commentaries on classics effect, and installation easy operation is swift.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a sheet metal component is with preventing following commentaries on classics riveting nut, its is including the body that is equipped with the blind hole, a side end of body is provided with the flange, the flange with the position that the body is connected is provided with cyclic annular first flower tooth, a serial communication port, the body is the column, the body includes riveting district, threaded connection district, guide area, rivet-pulling district, threaded connection district is the internal thread, is located the inside opposite side of body, the guide area is for being located the inside counter bore of body, the counter bore is located threaded connection district with rivet-pulling between the district, the periphery of body is provided with cyclic annular second flower tooth.
It is further characterized in that the method further comprises the steps of,
the aperture of the rivet area is smaller than that of the counter bore, and the aperture of the counter bore is smaller than that of the threaded connection area;
the flange is annular, a through hole is formed in the middle of the flange, one side end of the body is open and is communicated with the through hole, and the other side end of the body is of a closed structure;
the first spline teeth are triangular and are uniformly distributed at intervals along the circumferential direction of a connecting part between the flange and the body;
the second spline comprises a plurality of strip-shaped grooves, the grooves are circumferentially distributed on the outer surface of one side of the body at intervals, and one side end, far away from the flange, of each groove is a conical groove.
The other side end of the body is provided with a chamfer.
Adopt the utility model discloses above-mentioned structure can reach following beneficial effect: the other side in the riveting nut body is provided with internal threads which can play a role of threaded connection; the first annular flower teeth are arranged between the body and the flange, the second annular flower teeth are arranged on the periphery of the body, and the arrangement of the first flower teeth and the second flower teeth increases the friction force between the riveting nut and the sheet metal part, so that the follow-up rotation prevention effect of the riveting nut is greatly improved; this riveting nut body is the column, when installing it and sheet metal component, need not to counterpoint, and its direction mainly relies on inside counter bore to realize, consequently, installation easy operation is swift, has improved the installation effectiveness greatly.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic sectional view taken along the line a-a in fig. 1.
Detailed Description
See figure 1, fig. 2, a sheet metal component is with preventing following commentaries on classics riveting nut, it is including body 1 that is equipped with the blind hole, a side end of body is provided with annular flange 2, the position that flange 2 is connected with body 1 is provided with cyclic annular first flower tooth 3, body 1 is the column, body 1 includes riveting zone 11, threaded connection district 12, guide area 13, rivet area 14, threaded connection district 12 is the internal thread, be located the inside opposite side of body 1, guide area 13 is for being located the inside counter bore of body 1, counter bore 13 is located between threaded connection district 12 and the rivet area 14, the periphery of body 1 is provided with cyclic annular second flower tooth 15.
The rivet pulling area 14 is a columnar cavity, the aperture of the rivet pulling area 14 is smaller than that of the counter bore 13, the aperture of the counter bore 13 is smaller than that of the threaded connection area 12, the middle part of the flange 2 is provided with a through hole 21, one side end of the body 1 is open and is communicated with the through hole 21, and the other side end of the body 1 is of a closed structure 10;
The riveting nut is applied to the installation of a television circuit board, a television shell, an LED screen and the like, in order to avoid the damage of the circuit board caused by water leakage or meet the requirements of water resistance, light tightness and the like of the LED screen, the body 1 of the riveting nut is arranged to be of a blind hole type structure, namely, one end of the body 1 is open, and the other end is closed; when the riveting nut is installed on a sheet metal part by adopting a riveting machine, the internal thread of the thread connecting area 12 is in threaded connection with the sheet metal part, the anti-follow-up rotation effect of the riveting nut is improved through the first flower teeth and the second flower teeth, and therefore the firmness of connection between the riveting nut and the sheet metal part is improved.
