A bed frame comprises a bed frame, a bed platform, a front plate, a distal plate, and two separate siderails at each side. The bed platform is structured by plurality of plates made by injecting plastics from a mold and serving to enhance the structure. The elevation angle of the bed platform can be adjusted by a driving device. Each of the siderails can be lifted or descended so that the patient can get on or off the bed conveniently. The outer side of each siderail is installed with at least one inner concave groove for fingers insertion when pull or push the siderails for safely purpose. Inner side of one siderail is installed with a motor controller to drive the driving device. The design will prevent the event of losing or destroying since it is fixed at a proper place. Besides, lower corners of the front and distal plates are installed with an impact-proof head to prevent the patient or others from being harmed by the corners. In particular, movable clamping pieces comprising a fixing seat, a pressing plate, a movable rear clamping plate, and a tightening block, are preset to the front plate and distal plate. With the special connection of the movable clamping pieces, the front plate and distal plate can be assembled or detached conveniently and easily.
