The invention discloses a novel air conditioner cabinet body structure. The structure comprises an air inlet assembly and an air outlet assembly detachably arranged on the air inlet assembly; the air inlet assembly comprises an air inlet assembly box body, a first air inlet and a first air outlet, wherein the first air inlet and the first air outlet are formed in the air inlet assembly box body; the first air inlet is connected with an external-connection air blower; the air outlet assembly comprises an air outlet assembly box body, a second air inlet and a second air outlet, wherein the second air inlet and the second air outlet are formed in the air outlet assembly box body; the first air outlet of the air inlet assembly is fixedly arranged on the second air inlet of the air outlet assembly through a bolt; and when the air conditioner cabinet body structure needs to be matched with positions of air inlets and air outlets of different air conditioner cabinet bodies, the structure can adapt to changes of the positions of the air inlets and the air outlets of the different air conditioner cabinet bodies only through replacement of the air inlet assembly, the air conditioner cabinet body structure does not need to be wholly replaced, the mold development cost is reduced, the production cost is saved, and generality is high.
