Description

Rivet

Technical Field

The utility model relates to a rivet field especially relates to a rivet.

Background

Rivets are nail-shaped articles used to connect two parts with through holes and a cap at one end. In riveting, the riveted parts are connected by self-deformation or interference. Rivets are of many kinds and are not limited in form. After daily use, the outer wall of the rivet is abraded due to friction with the part, so that errors occur in connection between the part and the rivet.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a rivet can improve the riveted steadiness.

The utility model provides a technical scheme that its technical problem adopted is: a rivet comprising a structural body, the structural body comprising: the nail rod and locate the head of nail rod upper end, the nail rod is the cylinder, cylindrical hole has been dug to the inside of nail rod, the bottom of nail rod is equipped with the dentate breach, breach equidistance evenly distributed in the bottom of nail rod.

Furthermore, the nail rod and the head are integrally formed;

further, the radius of the head is larger than that of the nail rod;

furthermore, a long-strip-shaped groove is dug in the outer wall of the nail rod, and the depth of the groove is smaller than the wall thickness of the nail rod;

furthermore, the head is in a circular truncated cone shape, and the side surface and the upper end surface of the head are friction surfaces;

furthermore, the outer wall of the nail rod is a smooth surface.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a rivet, set up the dentate breach in the bottom of the nail pole, after riveting, can expand the lower extreme of nail pole outwards, block the part, improve the stability of part riveting; meanwhile, the platform-type head is arranged, so that the stress area when riveting is carried out by using tools such as a hammer and the like is increased, and the riveting efficiency is improved; set up the recess at the outer wall, can save the material on the one hand, conveniently press from both sides simultaneously and get.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A rivet of the present invention is described in detail below with reference to fig. 1-2: a rivet comprising a structural body, the structural body comprising: the nail pole 1 and locate head 2 of 1 upper ends of nail pole, nail pole 1 is the cylinder, 1 inside cylindrical hole 3 that has dug of nail pole, the bottom of nailing pole 1 is equipped with

dentate breach

4, 4 equidistance evenly distributed in of breach 1's bottom.

The nail rod 1 and the head 2 are integrally formed; the radius of the head 2 is larger than that of the nail rod 1; a long-strip-shaped groove 5 is dug in the outer wall of the nail rod 1, and the depth of the groove 5 is smaller than the wall thickness of the nail rod 1; the head 2 is in a circular truncated cone shape, and the side surface and the upper end surface of the head 2 are friction surfaces 6; the outer wall of the nail rod 1 is a smooth surface.

The working principle is as follows: the rivet is arranged between the two parts with the holes 3, the rivet is riveted into the holes 3, and the two parts are fixed by utilizing the interference fit of the outer wall of the rivet and the parts; the lower end surface of the nail rod 1 is unfolded outwards by using a tool such as a hammer, so that a part can be clamped, or a fastening piece is inserted into the cylindrical hole 3 of the nail rod 1, so that riveting is completed.

To sum up, the bottom of the nail rod of the rivet is provided with the tooth-shaped notch, so that after riveting, the lower end of the nail rod can be unfolded outwards to clamp parts, and the riveting stability of the parts is improved; meanwhile, the platform-type head is arranged, so that the stress area when riveting is carried out by using tools such as a hammer and the like is increased, and the riveting efficiency is improved; set up the recess at the outer wall, can save the material on the one hand, conveniently press from both sides simultaneously and get.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
