The invention relates to a storage cargo outlet method for a storage rack, which is characterized in that a storage plate for storing cargos is inclined so that the surface of the storage plate becomes an inclined surface, the bottom of the inclined surface is provided with a position limiting element used for preventing the cargos from downwards sliding, the cargos are placed on the inclined storage plate, and the cargos are arranged at the inclined surface above the position limiting element one by one, when the cargo delivery is needed, the cargos to be outlet tightly leaning on the position limiting element are firstly lifted, in addition, the cargos are higher than the position limiting element, the cargos exceed the position limiting element under the gravity effect of the cargos above the inclined surface and slide out of the storage plate in inclined arrangement, and the subsequent cargos slide to the position limiting element and are blocked on the storage plate in inclined arrangement by the position limiting element. The storage rack comprises a support frame, wherein the storage plate is connected onto the support frame and is in inclined arrangement, the position limiting element is arranged on the storage plate and is positioned at the downstream part of the storage plate in the inclined arrangement, a through hole is arranged on the storage plate and is adjacent to the position limiting element, and a lifting mechanism is arranged under the through hole.
