Description

Anti-twist rivet

Technical Field

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 7, an embodiment of the present invention includes:

the first embodiment is as follows:

an anti-twist rivet comprising: the riveting shell comprises a riveting shell 1 and a rivet core 2, wherein the rivet core 2 is arranged in the riveting shell 1 in a penetrating manner, the riveting shell further comprises an upper plate 3 and a lower plate 4, non-circular holes 5 are formed in the upper plate 3 and the lower plate 4, a non-circular boss 6 matched with the non-circular holes 5 is convexly arranged on the riveting shell 1 and is suitable for preventing the upper plate 2 from rotating circumferentially along the lower plate 4, the non-circular holes 5 are elliptical holes, and the non-circular boss 6 is an elliptical boss; when using, put into the rivet in the non-round hole 5 on upper plate 3 and hypoplastron 4, connect the rivet on upper plate 3 and hypoplastron 4 through the rivet rifle, make the inseparable connection of upper plate 3 and hypoplastron 4 be in the same place, reach the effect of fastening, through the cooperation of non-round boss 6 and non-round hole 5 on riveting shell 1, oval boss is located oval hole promptly, oval boss can't rotate along oval hole, thereby make upper plate 3 and hypoplastron 4 can't produce relative wrench movement, the effect of fastening has been improved.

Example two: the first embodiment is basically the same as the first embodiment, except that the non-circular hole 5 is a polygonal hole, the non-circular boss 6 is a polygonal boss, the number of the sides of the non-circular hole 5 is not less than 3, the number of the sides of the non-circular boss 6 is not less than 3, and the polygonal boss is located in the corresponding polygonal hole and cannot rotate circumferentially, so that the upper plate 3 and the lower plate 4 cannot twist relatively, and the fastening effect is improved.

The thickness of the non-circular boss 6 is equal to the sum of the thicknesses of the upper plate 3 and the lower plate 4, so that the contact area of the non-circular boss 6 with the upper plate 3 and the lower plate 4 is the largest.

The non-circular bosses 6 are in clearance fit with the non-circular holes 5, so that rivets can be conveniently placed in the non-circular holes 5 on the upper plate 3 and the lower plate 4 for fastening connection, and the use convenience is improved.

To sum up, the utility model provides an anti-twist rivet, simple structure, processing is easy, through the non-circular boss on the riveting shell, makes the upper plate and the hypoplastron fastening that have the non-circular hole to the unable relative rotation of upper plate and hypoplastron has improved fastening connection's effect.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
