Abstract

La présente invention concerne un appareil permettant de régler la hauteur d'un flotteur d'un robinet d'entrée d'eau. Ledit appareil comprend un groupe d'engrenages de transmission et une tige filetée de réglage (1). L'extrémité supérieure de la tige filetée de réglage (1) pivote sur une extrémité d'une tige ascendante (6) du robinet d'entrée d'eau, et son extrémité inférieure comporte une partie filetée (11). La partie filetée (11) de la tige filetée de réglage (1) est vissée avec un trou de vis (21) du flotteur (2) pour régler la hauteur du flotteur (2), l'extrémité inférieure de la tige filetée de réglage (1) entraîne simultanément le groupe d'engrenages de transmission monté sur le fond d'un réservoir d'eau de petite taille (3), et les engrenages d'étages multiples (51, 52, 53) sont engrenés les uns avec les autres. Le moyeu de l'engrenage d'étage final (52) est formé avec un filet de vis (521) qui s'accouple avec un filet de vis (41) formé sur une paroi de tube d'un tube d'entrée d'eau (4). La tige filetée de réglage (1) est utilisée pour régler de façon synchrone la hauteur du réservoir d'eau de petite taille (3) par l'intermédiaire de l'accouplement du filet de vis (521) de l'engrenage d'étage final (52) et du filet de vis (41) du tube d'entrée d'eau (4). L'appareil est pratique pour régler de façon synchrone les hauteurs du réservoir d'eau de petite taille et du flotteur, et la plage de réglage est importante.
