摘要： A knob closure device for operating and locking two surfaces which are axially movable with respect to the knob, which comprises: a pin that can be coupled to the first surface and is affected by two annular end grooves; a hollow body that can be coupled to the second surface and supports, so that they can move axially and rotate, the actuation knob on one side and a disengagement cylinder on the other side, the knob and the cylinder being mutually coupled; a central bushing, which is rigidly coupled to the hollow body and in which two oppositely arranged inclined slots are formed that converge toward each other and toward the free end of the bushing; two transverse shafts that are slidingly mounted in the slots and are pushed by a compression spring in tangential engagement in the annular grooves to couple the pin to the bushing; a cam profile that is rigidly coupled to the inlet of the main body, against which a diametrical stem of the knob engages that is adapted to cause the axial sliding of the end of the cylinder to move the shafts into positions that are spaced from the stem and cause their disengagement.
摘要翻译：一种用于操作和锁定可相对于所述旋钮可轴向移动的两个表面的旋钮闭合装置，其包括：销，所述销可联接到所述第一表面并且受两个环形端槽的影响; 可以联接到第二表面并支撑的空心体，使得它们可以轴向移动并旋转，一侧的致动旋钮和另一侧的分离圆筒，旋钮和气缸相互连接; 中心衬套刚性地联接到中空本体，并且其中形成有两个相对布置的倾斜槽，所述倾斜槽相对于彼此并且朝向套管的自由端会聚; 两个横向轴滑动地安装在槽中并且被一个压缩弹簧推入，以与该环形槽相切地接合，以将该销连接到衬套上; 凸轮轮廓刚性地联接到主体的入口，旋钮的直径杆接合到该凸轮轮廓，其适于引起气缸的端部的轴向滑动，以将轴移动到与杆间隔开的位置并使其脱离接触。
