Ring groove rivet shank structure

Abstract

The invention relates to a ring groove rivet shank, comprising an upper part of the shank, a middle part of the shank and a lower part of the shank. The oblate head, the middle part of the nail shank and the lower part of the nail shank are cylinders, wherein the lower part of the nail shank is provided with several annular grooves evenly distributed along the axial direction of the lower part of the nail shank, and ring teeth are formed between adjacent annular grooves. The invention rationally utilizes the principle of Hooke's law, and according to the thickness of the riveting, the lower part of the nail rod can be broken at any position of the ring groove, which is flush with the matching collar, so that the riveting operation is not limited by the thickness of the riveting, and can achieve high quality and high strength. riveting, and no nails exposed after riveting, beautiful surface, good fixation, easy operation, low noise, reliable connection, especially designed for riveting in special fields such as aerospace, military industry, and rail transit.

Description

technical field [0001] The invention relates to a shank of a special-purpose rivet used for riveting equipment in the fields of aerospace, military industry, rail transportation, etc., in particular to a shank of a ring groove rivet. Background technique [0002] The ring groove rivet is a new type of riveted fastener. A set of ring groove rivets is composed of a nail rod and a collar. The ring groove rivet has a shockproof function and high-strength clamping force, and can replace conventional bolts and nuts. Because the ring groove rivet can achieve very high riveting strength, it is widely used in the manufacture of railway facilities such as airplanes and train carriages and the manufacture of containers. Since the position of the fracture groove is fixed, there is a higher requirement for the riveting thickness. If the thickness is thicker, the nail rod will shrink inside and affect the riveting strength. If the riveting is thinner, the nails will be exposed and cause s...

Because the ring groove rivet can achieve very high riveting strength, it is widely used in the manufacture of railway facilities such as airplanes and train carriages and the manufacture of containers. Since the position of the fracture groove is fixed, there is a high requirement for the thickness of the riveting. If the thickness is thicker, the nail rod will shrink inside and affect the riveting strength. If the riveting is thinner, the nails will be exposed and cause safety hazards.
