     Embodiment 2 
     Referring to  FIGS. 6-8 , a storage box having fireproof and heat-insulating functions includes a folding storage box body  1 . When the folding storage box body  1  is subjected to vibration, the vibration can be offset through the setting of a plurality of buffer springs  11 . When valuables are stored in the folding storage box body  1 , the shattering of items can be avoided through cushioning, thereby ensuring the safety of the items in the folding storage box body  1 . 
     In addition, when a connecting plate  10  is installed, four abutting plates  16  can clamp the folding storage box body  1  by pressing a plurality of pressing rods  15 , making the installation convenient. Similarly, the connecting plate  10  can be easily disassembled and reused, thereby saving social resources. 
     The working principle of the present disclosure is as follows. 
     In the present disclosure, a folding storage box body  1  can be in direct contact with open flames, and the product is resistant to high temperature, does not spontaneously ignite and has certain moisture-proof and heat-insulating functions. In the event of a fire, because the material is resistant to high temperature and does not spontaneously ignite, stored items cannot be in contact with open flames, so that they are protected, and the spread of the fire source can be controlled. When a plurality of fireproof boxes are stored together, a firewall is formed outside, which better protects important items and property and gives more time to firefighters to rescue important items. The material is not only fireproof, but also waterproof, has a certain moisture-proof function, better protects important documents, and prevents items from molding. In a large fire, if the temperature is too high, items stored in the product can be protected from damage caused by high temperature and burning within a certain period of time. Generally, in case of contact with small fires, the safety of items can be ensured. When flammable and explosive items such as a battery are stored, if there is a fire inside, the extension of the fire source can be controlled. Therefore, fire accidents are reduced. In addition, When the folding storage box body  1  is subjected to vibration, the vibration can be offset through the setting of a plurality of buffer springs  11 , thereby ensuring the safety of the items in the folding storage box body  1 . In addition, when a connecting plate  10  is installed, two pressing rods  15  on the same side can be first pressed, so that the pressing rods  15  rotate in a rotating hole  13  through a rotating shaft  14 , the pressing rods  15  rotate and pull springs  18  for stretching, then one side of the folding storage box body  1  is placed on the connecting plate  10 , two pressing rods  15  are loosened, so that the two pressing rods  15  return under the drawing force of two springs  18 , to drive two abutting plates  16  to abut against the folding storage box body  1  and then press the folding storage box body  1 , and two other pressing rods  15  are sequentially pressed. Therefore, the folding storage box body  1  can be completely placed on the connecting plate  10 , and two other pressing rods  15  are loosened, so that four abutting plates  16  can clamp the folding storage box body  1 , making the installation convenient. 
     The above descriptions are merely preferred specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Equivalent replacements or changes made by any person skilled in art according to the technical solutions and conception of the present disclosure within the technical scope disclosed in the present disclosure should fall within the protection scope of the present disclosure.
