The invention provides a connecting rod triggering type locking and unlocking device and a working method thereof. The locking and unlocking device comprises a rack, a locked piece, a locking rod, a reset tension spring, an unlocking rod, a middle rod, a lifting rod, a triggering block and a power mechanism, and the bottom of the locking rod is hinged to the rack; the unlocking rod and the liftingrod are arranged in a sliding groove in a sliding mode; the middle part of the middle rod is hinged to the rack, two ends of the middle rod are respectively hinged to the lower part of the unlockingrod and the lower part of the lifting rod; the top of the unlocking rod is matched with the locking rod, the triggering block is matched with the lifting rod, the reset tension spring is arranged at the middle lower part of the locking rod, and in an initial state, the triggering block lifts the lifting rod, so that the top of the unlocking rod is in contact with the locking rod, and the locking rod is far away from the locked piece under the action of the reset tension spring; and during locking, the power mechanism drives the triggering block and the lifting rod to move downwards, the middlerod rotates anticlockwise, the unlocking rod moves upwards, and the locking rod locks the locked piece. The connecting rod triggering type locking and unlocking device can be repeatedly used, is simple in structure, small in size and less in weight, and completes repeated connection and separation between spacecrafts.

    本发明提供了一种连杆触发式锁释装置及其工作方法,锁释装置包括机架、被锁件、锁紧杆、复位拉簧、解锁杆、中间杆、提拉杆、触发块和动力机构,锁紧杆的底部与机架铰接;解锁杆和提拉杆在滑槽内滑动设置;中间杆的中部与机架铰接,两端分别与解锁杆下部和提拉杆下部铰接;解锁杆的顶部与锁紧杆配合,触发块与提拉杆配合,在锁紧杆的中下部设置复位拉簧,初始状态下,触发块提拉提拉杆,使解锁杆的顶部与锁紧杆接触,锁紧杆在复位拉簧的作用下远离被锁件;锁紧时,动力机构带动触发块和提拉杆向下移动,中间杆逆时针转动,解锁杆向上移动,锁紧杆锁紧被锁件。本发明可重复使用、结构简单、小型化及轻量化,完成航天器之间的多次重复连接与分离。
