摘要:
The invention provides a locking device for locking together first and second elements that are movable relative to each other in an axial direction, the device comprising firstly a bushing secured to first element and including catches that are cantilevered-out in an axial direction and that are elastically deformable, and secondly an anchor portion secured to the second element and including an annular setback to receive hook-shaped ends of the catches, the device also including a locking sleeve mounted to move relative to the catches between a release position in which the catches are free to flex, and a blocking position in which the catches are prevented from flexing, wherein the locking sleeve is movable in rotation relative to the catches and includes a circumferential succession of gaps and of obstacles, such that: when the sleeve is in a first angular position corresponding to the release position, the gaps are in register with the catches which are therefore free to flex under the effect of the anchor portion moving; and when the sleeve is in a second angular position corresponding to the blocking position, the gaps are offset relative to the catches such that the catches are in register with the obstacles of the locking sleeve, thereby preventing the catches from flexing when their ends are engaged in the setback in the anchor portion.
摘要(中):
本发明提供了一种用于将第一和第二元件锁定在一起的锁定装置,所述第一和第二元件可在轴向方向上相对于彼此移动,所述装置首先包括固定到第一元件的衬套,并且包括在轴向方向悬伸的卡扣, 可弹性变形,其次是固定到第二元件的锚定部分,并且包括环形挫折件以容纳钩子的钩状端部,该装置还包括一个锁定套筒,该锁定套筒安装成相对于卡扣移动,在释放位置之间, 可自由弯曲,并且阻挡位置防止卡扣弯曲,其中锁定套筒相对于卡扣可旋转移动并且包括圆周连续的间隙和障碍物,使得当套筒处于 与释放位置相对应的第一角度位置,间隙与捕获器对准,因此,这些捕捉器可自由地挠曲 r锚定部分移动的效果; 并且当套筒处于对应于阻挡位置的第二角位置时,间隙相对于卡扣偏移,使得卡扣与锁定套筒的障碍物对准,从而防止卡爪在其端部接合时弯曲 在锚定部分的挫折。
