Locking mechanism for nuclear industry

According to the locking mechanism for the nuclear industry, a mechanical arm is used for clamping and rotating a locking rod, due to the fact that the locking rod is in threaded connection with a pressing sleeve and drives the pressing sleeve to move towards the direction of the locking rod, a locking groove hole is formed in the pressing sleeve, the diameter of the locking groove hole is smaller than that of a locking ball, and under the action of a locking cavity in the pressing sleeve and the locking sleeve, the locking ball is locked in the locking groove hole. And the locking ball can clamp and clamp the butt joint pin, so that equipment or parts can be quickly mounted or dismounted, and certain use value and popularization value are achieved. 本实用新型公开了一种核工业用锁紧机构，利用机械手夹住锁紧杆，旋转锁紧杆，由于锁紧杆与压套螺纹连接，带动压套向锁紧杆方向移动，压套上有锁紧槽孔，锁紧槽孔的直径小于锁紧球的直径，在压套与锁紧套内的锁紧腔作用下，锁紧球会夹紧并卡住对接销钉，实现设备或部件的快速安装或拆卸，具有一定的使用价值和推广价值。
