Abstract

La présente invention concerne un dispositif de déverrouillage à simple étrier pour un module optronique. Il comprend un fond de carter (1), un dessus de carter (2) une unité de manœuvre (3), un élément élastique (5) et un briquetage (6). Le fond de carter (1) est relié de façon fixe au dessus de carter (2). L'unité de manœuvre (3) est capable de pivoter dans un premier sens autour de son arbre de picot (3b). Quand une force extérieure provenant de l'opérateur s'applique sur l'unité de manœuvre (3), l'unité de manœuvre (3) pivote entre une position de verrouillage et une position de déverrouillage. L'élément élastique (5) est monté entre le dessus de carter (2) et l'unité de manœuvre (3). Sous l'effet de l'élément élastique, l'unité de manœuvre (3) est capable de pivoter dans le deuxième sens opposé au premier sens autour de l'arbre de pivot (3b). Enfin, le briquetage (6) est relié de façon fixe au dessus de carter (2) de façon à coopérer avec le dessus de carter (2) pour définir l'arbre de pivot (3b) autour duquel pivote l'unité de manœuvre (3). La présente invention intègre le dispositif en rotation et le dispositif d'arrêt, ce qui optimise la structure, simplifie le processus d'usinage des pièces et améliore la fiabilité des pièces. L'étrier peut revenir automatiquement en position de travail sans opération manuelle.
