Description

Closed type flat round head blind rivet Technical Field The utility model relates to the technical field of self-plugging rivets, in particular to a closed type oblate head self-plugging rivet. Background The rivet comprises a rivet body and a core rod, the core rod is pulled out through a rivet pulling gun during riveting, the rivet body is expanded to form firm mechanical connection, the rivet body is expanded after riveting to form reliable mechanical locking, the rivet is suitable for occasions bearing high loads, the closed type flat round head blind rivet is a single-sided riveted fastener, leakage is effectively prevented through the closed type design, the rivet is suitable for the occasions needing airtight or liquid-tight connection, and the rivet cannot be operated from two sides. In the prior art, a closed type flat round head self-plugging rivet is screwed up to the side wall of rivet cover through the die of rivet main part one end and is screwed up in, and rivet cover one end receives the die outward expansion and makes the rivet cover receive outside expanding force, produces the expansion force to work piece hole groove side, when the effort of screwing up is great, makes the easy damage that produces of the corner of work piece hole groove side easily, influences the performance that whole work piece was used. Therefore, the utility model provides a closed type oblate head blind rivet for solving the problems. Disclosure of utility model The utility model aims to provide a closed type oblate head blind rivet which is used for solving the problems in the background technology. The technical scheme is that the closed type oblate head self-plugging rivet comprises a rivet main body and a rivet sleeve, wherein the rivet sleeve is positioned on the outer surface of the rivet main body, a sealing ring is arranged on the outer surface of the rivet main body, a clamping groove is formed in the side wall of the sealing ring, one side of the rivet sleeve is positioned in the clamping groove, a fastening ring is arranged on the outer surface of the sealing ring, a plurality of open ring grooves are formed in the inner wall of the fastening ring, and the open ring grooves are uniformly distributed in an annular array. Preferably, the surface mounting of rivet main part has the expansion ring, and a plurality of stock is installed to the lateral wall of expansion ring, and the stock is annular array evenly distributed. Preferably, a clamping rod is installed at one end of the long rod, and penetrates into the open ring groove. Preferably, a sealing ring is arranged in the clamping groove, and a concave ring is arranged in the center of the side wall of the sealing ring. Preferably, the side wall of the sealing ring is provided with a convex ring, the convex ring and the concave ring are positioned on the same horizontal plane, and the convex rings are respectively positioned at the two sides of the concave ring at equal intervals. Preferably, one surface of the sealing ring is fixed on the inner wall of the clamping groove, and the other surface of the sealing ring is attached to the side wall of the rivet sleeve. Compared with the prior art, the utility model has the beneficial effects that: The utility model provides a pair of closed type oblate head self-plugging rivet utilizes the use of sealing ring and holding ring, and sealing ring carries out sealing connection through the draw-in groove to rivet main part and rivet cover, can press from both sides tightly fixedly with the work piece through the holding ring simultaneously, avoids the die directly to twist the strength that moves inside the rivet cover big, and treats the surface of fastening work piece and produce the damage.
