Title (EN) BLIND RIVET AND SEALING STRUCTURE
(FR) RIVET AVEUGLE ET STRUCTURE D'ÉTANCHÉITÉ
(JA) ブラインドリベット及び封止構造
Abstract:
(EN) The present invention relates to a blind rivet having sufficient airtightness and watertightness with a single blind rivet. This blind rivet (1) is provided with a rivet body (10) and a mandrel (30). The rivet body (10) has a flange (16), a flange taper portion (15), and a sleeve, and has a bottomed hole (18) formed at the bottom of the sleeve from the surface of the flange (16). The mandrel (30) has a head portion (31), a head taper portion (32), a U-shaped groove portion (33) with a U-shaped groove, a breakable portion (35) and a circular column portion (37). The head portion (31) of the mandrel (30) is disposed at the bottom of the bottomed hole (18) of the rivet body (10) and a shaft portion extends from the upper surface of the flange (16) of the rivet body (10). The sleeve of the rivet body (10) has an uneven portion (13) of an uneven shape, and the head portion (31) of the mandrel (30) is held at the bottom of the bottomed hole (18) of the rivet body (10) by the uneven portion (13). The mandrel (30) is pulled out and the diameter of the sleeve is enlarged by the head taper portion (32) to seal a base body between an enlarged diameter portion (21) and the flange.
(FR) L'invention concerne un rivet aveugle présentant une étanchéité à l'air et une étanchéité à l'eau suffisantes avec un seul rivet aveugle. Ce rivet aveugle (1) comprend un corps de rivet (10) et un mandrin (30). Le corps de rivet (10) comprend une bride (16), une partie conique (15) de la bride, et un manchon, et comporte un trou de fond (18) formé au fond du manchon depuis la surface de la bride (16). Le mandrin (30) comprend une partie tête (31), une partie conique (32) de la tête, une partie rainure en U (33) comportant une rainure en U, une partie cassable (35) et une partie colonne circulaire (37). La partie tête (31) du mandrin (30) est disposée au fond du trou de fond (18) du corps de rivet (10); et une partie arbre s'étend de la surface supérieure de la bride (16) du corps de rivet (10). Le manchon du corps de rivet (10) présente une partie irrégulière (13) de forme irrégulière, et la partie tête (31) du mandrin (30) est retenue au fond du trou de fond (18) du corps de rivet (10) par la partie irrégulière (13). Le mandrin (30) est retiré et le diamètre du manchon est agrandi par la partie conique (32) de la tête pour sceller un corps de base entre une partie de diamètre agrandi (21) et la bride.
(JA) ブラインドリベット単体で十分な気密性、水密性が得られるブラインドリベット。 ブラインドリベット(1)は、リベット本体(10)と、マンドレル(30)とを備える。 リベット本体は、フランジ(16)と、フランジテーパ部(15)と、スリーブとを有し、フランジの表面からスリーブの底部に有底孔(18)が形成される。 マンドレルは、頭部(31)と、頭部テーパ部(32)と、U形状の溝が形成されたU溝部(33)と、破断可能部(35)と、円柱部(37)を有する。 マンドレルの頭部は、リベット本体の有底孔の底部に配置され、軸部は、リベット本体のフランジの上面から延び出る。 リベット本体のスリーブは、凹凸形状の凹凸部(13)を有し、マンドレルの頭部は、凹凸部により、リベット本体の有底孔の底部に保持される。マンドレルを引き抜き、頭部テーパ部により、スリーブを拡径させて拡径部(21)とフランジの間に基体を封止する。
