The invention provides a buckle mounting structure and an air conditioner. The buckle mounting structure comprises a body and a buckle assembly, wherein a neck is formed in the body; the neck comprises a first opening and a second opening; the buckle assembly is inserted and clamped in the neck from the first opening; the buckling position of the buckle assembly is positioned in the second opening. The buckle assembly can be mounted by obliquely inserting the buckle assembly along the first opening without fixing through a screw, so that the mounting efficiency of a pre-mounted magnet on an air inlet panel is increased, and the labor cost is lowered.
