Space self-adaptive locking mechanism

The invention discloses a space self-adaptive locking mechanism. The locking mechanism comprises a fixed sliding rod, a lower sliding block, an upper sliding block, an end moving sliding block, a gasket and an end tightening screw. The contact angle between the end moving sliding block and the upper sliding block is alpha, the contact angle between the upper sliding block and the lower sliding block is alpha, the contact angle between the upper sliding block and the fixed sliding rod is alpha, and alpha is smaller than 90 degrees. The space self-adaptive locking mechanism is easy to achieve inspace on-orbit replacement, the length of the locking mechanism can be correspondingly adjusted according to the length of a unit plate, the space on-orbit replacement difficulty of the unit plate islowered, and the risk that the whole machine cannot work normally due to that the function of a certain part of the unit plate of equipment is lost is correspondingly lowered. 本发明公开了一种空间自适应锁紧机构，所述锁紧机构包括：固定滑杆、下滑块、上滑块、端部移动滑块、垫圈
