Abstract

La présente invention concerne une structure d'accouplement pour pointe de mélange et cartouche de matériau d'impression et, plus spécifiquement, un structure d'accouplement qui permet à une pointe de mélange accouplée à une cartouche de matériau d'impression de se coupler facilement et simplement à la cartouche de matériau d'impression, indépendamment du sens d'accouplement et qui permet, simultanément, d'éliminer complètement tout risque de fuite de matériau d'impression provoquée par le desserrement de la pointe de mélange quand la pointe de mélange entre en rotation sous l'effet de la pression générée par le mélange du matériau d'impression à l'intérieur de la pointe de mélange. La présente invention comprend : à l'intérieur d'une partie couvercle, une rainure de réception destinée à recevoir un connecteur, où une saillie sur un côté de périphérie extérieure dudit connecteur et une rainure en saillie et des pièces d'enclenchement sur la périphérie intérieure de la rainure de réception correspondent au connecteur qui comporte des rainures d'enclenchement formées à des intervalles de 90°, de façon que le connecteur soit pris dans la rainure de réception et que, simultanément, la partie couvercle s'y insère indépendamment du sens d'accouplement et puisse tourner à des intervalles de 90° quand la pointe de mélange est accouplée à la cartouche de matériau d'impression et que le desserrement de la pointe de mélange au moyen des pièces d'enclenchement qui sont insérées dans les rainures d'enclenchement formées à des intervalles de 90° soit empêché et que la pointe de mélange ne tourne pas sous l'effet de la pression générée quand le matériau d'impression est mélangé dans la pointe de mélange. La structure d'accouplement selon l'invention permet l'accouplement simple de la cartouche et de la pointe de mélange, de façon que leurs positions soient correctes, par insertion des conduits de raccordement du connecteur dans les conduits de décharge quand les pièces d'enclenchement s'insèrent dans les crochets en saillie formés dans la partie supérieure de la cartouche de matériau d'impression ; et ajustement de la partie couvercle, indépendamment du sens d'accouplement quand la pointe de mélange est accouplée à la cartouche de matériau d'impression, de façon à faciliter l'enclenchement des pièces d'enclenchement dans les rainures d'enclenchement du connecteur par rotation de la partie couvercle à des intervalles de 90° et la séparation des pièces d'enclenchement prises dans les rainures d'enclenchement quand la partie couvercle tourne de nouveau dans le sens inverse à des intervalles de 90°, ou l'enclenchement des pièces d'enclenchement dans les rainures d'enclenchement du connecteur quand la partie couvercle tourne à des intervalles de 90° et la séparation des pièces d'enclenchement prises dans les rainures d'enclenchement quand la partie couvercle tourne de nouveau dans le sens inverse à des intervalles de 90°.
