Energy-saving, consumption-reducing and heat-insulating outer protective box with multiple protections

The utility model provides an energy-saving, consumption-reducing and heat-preserving outer protective box with multiple protections, which comprises a box body and a box cover, one end of the box body is hinged with one end of the box cover through a hinge, a fixing assembly is arranged in the box body, and the fixing assembly comprises two clamping plates and a bidirectional threaded rod. The two-way threaded rod is rotationally connected to the middle position of the inner bottom wall of the box body through a bearing, one end of the outer portion of the two-way threaded rod is sleeved with a driven gear, one end of the inner side wall of the box body is provided with a rotating handle, and the bottom end of the rotating handle is connected with a driving gear; limiting blocks are symmetrically connected to the two ends of the two clamping plates, and limiting grooves are symmetrically formed in the inner side wall of the box body. The heat preservation box has the advantages that the space size of the hea
