Abstract

L'invention concerne une structure de suppression de conduit de fumée de type tige à liaison articulée utilisée dans un spectrophotomètre d'absorbance atomique. Le spectrophotomètre d'absorbance atomique comprend un boîtier de corps principal cylindrique et un conduit de fumée cylindrique. Le conduit de fumée est monté sur le boîtier de corps principal de telle sorte que la partie inférieure du conduit de fumée est insérée à l'intérieur du boîtier de corps principal, des rainures de limitation sont situées au sommet d'une paire de parois latérales de boîtier de corps principal dans la direction gauche-droite du boîtier de corps principal, des parties en saillie sont situées à des positions correspondant aux rainures de limitation lorsque le conduit de fumée est monté sur le boîtier de corps principal, ou des rainures de limitation sont situées sur le fond de la paire de parois latérales de conduit de fumée sur les directions gauche et droite du conduit de fumée, les parties en saillie étant situées à des positions correspondant aux rainures de limitation lorsque le conduit de fumée est situé sur le boîtier de corps principal, et lorsque le conduit de fumée est monté sur le boîtier de corps principal, les saillies s'ajustent à l'intérieur des rainures de limitation. La structure de suppression de conduit de fumée de type tige à liaison articulée comprend une paire de tiges de liaison, une extrémité de la paire de tiges de liaison étant reliée chacune de façon rotative à la paire de parois latérales de conduit de fumée, et l'autre extrémité de la paire de tiges de liaison étant reliée chacune de façon rotative et mobile à la paire de parois latérales de boîtier de corps principal.
