A safety frame is a device carried on the back of one person to prevent weights falling off from the air from impacting the person. The safety frame is mainly composed of a top frame, supporting frames, back straps, lap blocks, clamping devices and adjusting segments. Four leg columns are fixed by two sets of transverse strips, the upper portion is capped, and the frame is formed. The user is located in the supporting frames, the back straps are hung on the two shoulders, and the supporting frames can leave the ground by a proper distance. A corresponding distance exists between the top frame and the head top of the user. The user can carry the safety frame on the back to walk, run and the like. Once the weights fall off from the air and are pressed on the top frame, the back straps are stretched immediately by the supporting frames, and the leg columns of the supporting frames are on the ground and bear the inertia and weight of the weights. The user can be safe and sound. The safety frame is suitable for the aftershock period of earthquakes, and suitable for patrol and rush emergency on streets and roads, patrol of tunnels possible to collapse, ground floor rush emergency of dangerous buildings and other work.
