The invention provides an anti-falling protection device. The anti-falling protection device is used for preventing a lifting part from falling, the anti-falling protection device comprises a connecting base stop block and an elastic part, wherein the stop block is connected with a connecting base, the stop block has an avoiding state allowing the lifting part to pass through and a stopping statefor stopping the lifting part to fall, the stop block is arranged between the avoiding state and the stopping state in a switchable mode so as to drive the stop block to switch from the stopping stateto the avoiding state when the lifting part moves upwards, the elastic part is arranged between the stop block and the connecting base, so that the stop block is reset from the avoiding state to thestopping state after the lifting part passes through the stop block. The anti-falling protection device solves the problems that an anti-falling protection device in the prior art is more complex in structure and needs manual intervention.

    本发明提供了一种防坠保护装置,用于防止升降件下坠,防坠保护装置包括:连接座挡块,挡块与连接座连接,挡块具有使升降件通过的避让状态和用于止挡升降件下降的止挡状态,挡块在避让状态和止挡状态之间可切换地设置,以在升降件向上移动时带动挡块由止挡状态切换至避让状态;弹性件,设置在挡块和连接座之间,以在升降件通过挡块后,使挡块由避让状态复位至止挡状态。本发明的防坠保护装置解决了现有技术中的防坠保护装置结构较为复杂且需要人工干预的问题。
