Abstract
The utility model relates to a self-fastening expansion-riveting nut. The nut is shaped like a cylinder, the upper part of the nut is provided with an expansion-riveting brim, a threaded hole is drilled in the middle of the nut, the bottom of the expansion-riveting brim is provided with a cylindrical projection, the top of the cylindrical projection is provided with umbelliform teeth, and the bottoms of the cylindrical projection and the nut are provided with a step; the inner side of the expansion-riveting brim is provided with a slope; the inner side of one end of the cylindrical projection, which is close to the expansion-riveting brim, is provided with a groove; the outer side of the end of the cylindrical projection, which is close to the expansion-riveting brim, is provided with a chamfer; the threaded hole is a blind hole; and one end of the threaded hole, which is close to the expansion-riveting brim, is provided with a counterbore. After the structure is adopted, when a machine is used for expanding and riveting the self-fastening expansion-riveting nut, the internal thread cannot be destroyed, and thereby the rate of finished products is increased; expansion riveting can be better carried out due to the slope; the structure of the self-fastening expansion-riveting nut is simple, the self-fastening expansion-riveting nut is easy to fabricate, the using effect of the self-fastening expansion-riveting nut is good, a sheet which can be as thin as 0.3mm to the max can be riveted by the self-fastening expansion-riveting nut, and the self-fastening expansion-riveting nut also can connect other parts.
Description
Technical field
The utility model relates to a kind of nut, especially relates to a kind of from the fastening anchor rivet bush.
Background technique
At present, market tightens the thin plate that connects 0.3mm, and the fastening piece that can connect other part also belongs to blank.The thin plate method of using both at home and abroad of being fastenedly connected has now: 1) nut or screw are welded on the sheet material with welding machine, and then combine with other part, because it is thin that 0.3mm sheet material compares, after the welding machine welding is gone up, the sheet material easy deformation, influence is normal to be used, and outer surface is not attractive in appearance yet, so infeasible.2) use common colored tooth pressure riveting product also infeasible, because the minimum use of self-clinching nut or self-clinching stud thickness of slab is more than the 0.7mm.3) it is more infeasible to use the most traditional screw-nut to connect, because tapping in the above on the Bao plate so also just can't be connected with other part.4) use foreign latest thin plate riveting technology: no riveting riveted joint and puncture riveted joint certainly, this technology can only make two thin plates be connected, but can't be connected with other part, and this product does not have this function, so can't use yet.5) use the staking nut also infeasible, because sheet material has only 0.3mm, staking nut riveted joint gauge of sheet is more than 0.5mm.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be fastenedly connected the not damaged screw of the above sheet material of 0.3mm and can connect again other part from the fastening anchor rivet bush.
The technical scheme in the invention for solving the technical problem is: a kind of from the fastening anchor rivet bush, nut is cylindrical body, the top of nut is provided with the riveting limit of rising, the centre is drilled with tapped hole, it is outstanding to be provided with cylindrical body below the described riveting limit of rising, cylindrical body is outstanding to be provided with step with the nut below, and the top of step is provided with the umbrella shape tooth.
For in the riveting of rising, the riveting limit of rising is riveted on the matrix, described inboard of rising by the riveting limit is provided with the slope.
In order to make in riveted joint, matrix can with combine closely from the fastening anchor rivet bush, described cylindrical body is given prominence to and is being provided with groove near the inside of riveting limit one side of rising.
Imbed for convenience in the sheet material, described cylindrical body is given prominence in the outside near riveting limit one side that rises and is provided with chamfering.
In order to completely cut off entering of exterior object, described tapped hole is a blind hole.
In order to guarantee when pressing, can not damage by double thread, described tapped hole is provided with counter sink in the side near the riveting limit of rising.
The beneficial effects of the utility model are: adopt after this kind structure, using machine to when the fastening anchor rivet bush rises by riveting, can not destroy internal thread, yield rate rises; The slope riveting of can better rising is arranged; Be provided with the umbrella shape tooth above, riveted joint back integral body can not rotated; Finish the installation of product from the attachment face of mounting plate, the complete embedding in the mounting plate back side is flat, keeps smooth smooth; Do not need tapping after the riveted joint, riveted joint is firm, the efficient height; Adapt to of the requirement of big industrial production automation to high quality, high efficiency, low cost, low energy consumption.The utility model is simple in structure, makes easily, and using effect is good.

Embodiment
A kind of as depicted in figs. 1 and 2 from the fastening anchor rivet bush, nut is cylindrical body, the top of nut is provided with the riveting limit 5 of rising, the centre is drilled with tapped hole 1, below the described riveting limit 5 of rising, be provided with cylindrical body outstanding 3, the top of cylindrical body outstanding 3 is provided with umbrella shape tooth 8, and cylindrical body outstanding 3 is provided with step 2 with the nut below; Described inboard of rising by riveting limit 5 is provided with slope 6; Described cylindrical body outstanding 3 is provided with groove 4 in the inside near riveting limit 5 one sides that rise; Described cylindrical body outstanding 3 is provided with chamfering 7 in the outside near riveting limit 5 one sides that rise; Described tapped hole 1 is a blind hole; Described tapped hole 1 is provided with counter sink 9 in the side near the riveting limit 5 of rising.
Sheet material is placed on the top of cylindrical body outstanding 3, the riveting limit 5 of rising is placed in the mounting hole of sheet material, the punch die sleeve pipe of riveting press is placed on the step 2, at the back side of sheet material, puts the tool of a respective model in slope 6, after riveting press is depressed, in descending jointly of tool, riveting limit 5 spreadings that rise, umbrella shape tooth 8 is compressed in the sheet material simultaneously, so just realize sheet material with from being connected of fastening anchor rivet bush, can realize being connected of sheet material and other parts from the tapped hole 1 at fastening anchor rivet bush center.
