The invention relates to a heat preservation meal box convenient to use. The heat preservation meal box convenient to use comprises a barrel body, connecting devices and a handle. The barrel body includes a barrel cover, a first barrel body, a second barrel body and a third barrel body. The connecting devices are symmetrically arranged at the two ends of the outer surface of the third barrel body.L-shaped limiting grooves structurally matched with the connecting devices are fixedly formed in the outer surface of the first barrel body. Each connecting device comprises a fixed groove, a rotating shaft b and a connecting rod. The fixed grooves are fixedly connected with the outer surface of the third barrel body. The connecting rods are rotationally connected with the fixed grooves through the rotating shafts b. Each connecting rod comprises a first connecting rod and a second connecting rod. The first connecting rods and the second connecting rods are of U-shaped structures. The lower ends of the first connecting rods are rotationally connected with the fixed grooves by the rotating shafts b. The upper ends of the first connecting rods are arranged on the exteriors of the second connecting rods in a sleeved mode. The outer surfaces of the L-shaped limiting grooves are fixedly provided with magnets b. The second connecting rods and the L-shaped limiting grooves are connected by the magnets b. The heat preservation meal box convenient to use has the advantages of being convenient to use and stable and reliable in connection.
