Abstract

L'invention concerne une structure de vis femelle (1) permettant, par un serrage aisé, d'obtenir une résistance d'accouplement élevée. Comme le montre la figure 5, la structure est munie d'une première vis femelle (2) et d'une seconde vis femelle (3) qui forment une paire. La première vis femelle (2) présente une partie convexe (2b) qui : diminue en termes de diamètre de l'extrémité de la base (2c) à une extrémité jusqu'à la pointe (2d) ; présente à l'intérieur des rainures hélicoïdales formées en continu avec des rainures hélicoïdales de la première vis femelle (2); et est munie d'une partie de mise en prise (2g) sur sa surface périphérique extérieure. La seconde vis femelle (3) présente une partie concave (3b) qui : diminue en termes de diamètre de l'extrémité d'ouverture (3d) à une extrémité jusqu'à la surface inférieure (3c) ; présente un trou débouchant formé à l'intérieur qui est en communication avec un trou à rainure hélicoïdale (3e) de la seconde vis femelle (3) ; et est munie d'une partie de réception de mise en prise (3g) sur sa surface périphérique intérieure. Lorsque la première vis femelle (2) et la seconde vis femelle (3) sont vissées ensemble sur une vis mâle (B), la partie convexe (2b) et la partie concave (3b) s'ajustent l'une à l'autre, et la partie de mise en prise (2g) et la partie de réception de mise en prise (3g) sont mises en prise. Ainsi, la première vis femelle (2) et la seconde vis femelle (3) sont accouplées de manière à empêcher une rotation relative dans au moins une direction.
