The invention discloses a safety belt locking device which comprises a safety belt fixing frame, a locking assembly, a control assembly and an inhaul cable. The locking assembly comprises a rotating block, a steel ball, a locking clamping jaw and a supporting disc, the rotating block is rotationally connected with the safety belt fixing frame, a mounting groove is formed in the rotating block, the supporting disc is arranged at the bottom of the mounting groove, the locking clamping jaw is rotationally arranged at the top of the mounting groove, the supporting disc and the locking clamping jaw are arranged diagonally, and the steel ball is arranged in the mounting groove. The steel balls abut against the supporting disc and the locking clamping jaws respectively. The inhaul cable is connected with the control assembly and the rotating block. When the seat backrest rotates, the control assembly obtains the rotating angle of the seat backrest and controls the inhaul cable to move so as to drive the rotating block to rotate, so that the angle of the seat backrest is compensated by adjusting the angle of the rotating block, and it is guaranteed that the locking assembly can work normally when the angle of the seat backrest changes; and real-time guarantee is provided for life safety of passengers.

    本发明公开了一种安全带锁止装置,包括:安全带固定框架、锁止组件、控制组件和拉索;锁止组件包括转动块、钢球、锁止卡爪和支撑圆盘,转动块与安全带固定框架转动连接,转动块内具有安装槽,支撑圆盘设置在安装槽的底部,锁止卡爪转动设置在安装槽的顶部,且支撑圆盘与锁止卡爪对角设置,钢球设置在安装槽,且钢球分别与支撑圆盘和锁止卡爪抵接;拉索分别与控制组件和转动块连接。当座椅靠背发生转动时,控制组件获取座椅靠背的转动角度,并通过控制拉索移动,进而带动转动块发生转动,从而通过调整转动块的角度以补偿座椅靠背的角度,保证了锁止组件在座椅靠背的角度发生变化时能够正常工作,对乘员的生命安全提供实时保障。
