Closed type blind rivet

Abstract

The invention discloses a closed type blind rivet. The closed type blind rivet comprises a rivet core rod and a rivet body, wherein the rivet body is of a tubular structure with a closed head, and a radial outer convex table used as a rivet cover is arranged on the tail part of the rivet body in the circumferential direction; a head of the rivet core rod is fixed in the rivet body, and a tail partof the rivet core rod penetrates through the rivet body and extends out of the rivet cover; and annular grooves are formed in the outer wall of the rivet body in the circumferential direction. According to the closed type blind rivet, the annular grooves are additionally formed in the outer wall of the rivet body of an ordinary closed type blind rivet, so that machining and manufacturing are simple, the riveting range is wide, pressure to the surface of a riveting object is small, the closed type blind rivet is suitable for connection between riveted parts with various thicknesses and multi layers of thin plates, the hole filling performance is excellent, the blind rivet can be used for large holes and irregular holes, and is completely inserted into the riveted holes, and has the advantages of leakage-proof, shockproof, waterproof, falling off prevention of the nail core head and the like , and therefore the trouble caused by selecting and using the blind rivets of different specifications in the riveting operation process is solved, the working efficiency is improved, and meanwhile, the stock amount of a warehouse is also saved.

Description

technical field [0001] The invention relates to a blind rivet, in particular to a closed blind rivet. Background technique [0002] The closed blind rivets usually used are composed of a nail core and a nail body. The closed blind rivets of this structure are riveted by a blind rivet gun during the riveting process, and the closed blind rivets are riveted The nail mandrel is pulled out so that the end of the nail body forms a drum shape to achieve riveting effect. In the operation process of the riveted connection of the riveted parts, it is often necessary to select the matching closed blind rivets according to the thickness of the riveted parts for riveting processing. The thickness of the riveted parts is different, and the closed blind rivets are selected. The specifications are also different. In order to facilitate the riveting operation, it is necessary to have a variety of blind rivets of different specifications, which will not only increase the inventory of the w...
