The invention discloses a self-adaptive four-point locking device of a rocket ejection seat lifesaving bag. The self-adaptive four-point locking device comprises a locking plate, a locking block, a rear locking assembly and a front locking assembly, wherein the locking plate and the locking block are arranged on the lifesaving bag; the rear locking assembly comprises a locking pin and a compression spring, and a groove is formed in the locking plate; the locking block comprises a rotating shaft part and a limiting part, the front locking assembly comprises a rotating block and a torsional spring, and the rotating block comprises a fork-shaped part; during locking, the front end of the locking pin is clamped in the groove to restrain the locking plate, the rotating shaft part is located at the inner corner of the fork-shaped part and limited and cannot move upwards, and the limiting part is located in the fork-shaped part and abuts against the fork-shaped part downwards. When the person and the chair are separated, counter-acting force generated at the moment of parachute shooting can drive the locking plate to release constraint and then move upwards along with the rear end of the lifesaving bag, then the torsion spring drives the rotating block to rotate while the limiting part is driven to rotate around the rotating shaft part till an opening of the fork-shaped part faces upwards, and the locking block is disengaged. The device can fix the life-saving bag in the chair basin at four points, can automatically unlock when a person is separated from the chair, and is convenient to use.

    本发明公开一种火箭弹射座椅救生包的自适应式四点锁定装置,包括设在救生包上的锁片和锁块以及设在火箭弹射座椅上的后锁定组件和前锁定组件;后锁定组件包括锁定销和压缩弹簧,锁片上设有凹槽;锁块包括转轴部和限位部,前锁定组件包括旋转块和扭簧,旋转块包括叉形部;锁定时,锁定销前端卡在凹槽内将锁片约束,转轴部位于叉形部的内角处且被限位无法上移、限位部位于叉形部内且向下抵住叉形部;人椅分离时,射伞瞬间产生的反作用力能带动锁片解除约束后随救生包后端向上运动,继而带动限位部绕转轴部旋转的同时扭簧带动旋转块旋转,直至叉形部开口朝上供锁块脱出。该装置能将救生包四点固定在椅盆内且能在人椅分离时自动解锁,使用方便。
