Lifting bed safety protection device

The invention provides a lifting bed safety protection device and relates to the field of medical lifting beds. The lifting bed safety protection device comprises an inner scissor arm, an outer scissor arm and a connecting seat. When a bed descends and encounters an obstacle during the falling process, the connecting seat receives resistance; as the resistance increases, the thrust of an electric push rod decreases, an adjusting spring pushes the connecting seat to rotate clockwise, so that a trigger plate comes into contact with a limit switch, to stop the medical lifting bed. The lifting bed anti-extrusion protection device can effectively perform shutdown and avoid accidents when there are articles or children under a bed board during descending of the medical bed, and the lifting bed safety protection device has the advantages of reasonable design and simple structure. 种升降床安全保护装置，涉及医用升降床领域。该升降床安全保护装置，包括剪刀内臂、剪刀外臂和连接座，当床下降过程遇到障碍物时，连接座受到阻力，随着阻力增大，电动推杆的推力减小，调整弹簧推动连接座顺时针旋转，使触发板与限位开关接触，使医用升降床停止运动。该升降床防挤压保护装置可以在
