The invention discloses a self-locking type safe opening and closing device. The device comprises a transmission device, a first self-locking device, an opening and closing device and a second self-locking device installed on a rack, a mechanical set in the transmission device operates to drive a locking block to move forwards, and after the locking block moves forwards by a certain distance, a spring jacking column on the second self-locking device enters a groove in the locking block to be locked, when unlocking is needed, the mechanical set in the first self-locking device operates to drivea driven wedge block to move upwards, after the wedge block moves upwards, a return spring contracts to drive a non-return block to move backwards away from a ratchet wheel, a mechanical set in the second self-locking device operates, the mechanical set in the transmission device operates to drive a jacking column to move upwards, and the mechanical set in the transmission device operates to drive the locking block to move backwards to open the device.
本发明公开了一种自锁式安全开合装置，包括传动装置、第一自锁装置、开合装置和第二自锁装置安装在机架上，传动装置内部机械组运转带动锁块进行前移，待锁块前移到一定距离后，第二自锁装置上的弹簧顶柱进入锁块上的槽内进行锁死，当需要打开时第一自锁装置内部机械组运转带动被动楔块上移，当楔块上移后，回位弹簧收缩带动止逆块后移远离棘轮，第二自锁装置内部机械组运转传动装置内部机械组运转带动顶柱上移，传动装置内部机械组运转带动锁块后移打开装置。
