Description
Technical field
This is novel relates to a kind of cutlery box, relates in particular to a kind of portable extension type fresh-keeping cutlery box.
Background technology
Cutlery box is the most general apparatus of people's food carrying, but the temperature that general crisper can only be controlled inner food or beverage does not rise, and can not carry out low-temperature preservation to food, and during the broiling summer, food is put into crisper can be rotten fast, can not eat.
Introduced a kind of portable refrigerator in Chinese invention patent CN102022880A, reach the purpose of chilled food by being filled with cold-producing medium in refrigerating chamber, but the refrigerator in this invention cannot stretch, cannot adjust the size of storeroom according to the number of food in storeroom, can not effectively utilize space and the energy.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of portable extension type fresh-keeping cutlery box.
Portable extension type fresh-keeping cutlery box of the present utility model, comprise casing and top cover, also comprises alignment pin, and described casing is comprised of upper box and lower box, and described upper box is connected by described alignment pin with lower box, and described top cover is arranged on described upper box.
Described upper box, lower box and top cover all are comprised of inner metal layer, refrigerant layer, intermediate metal layer, heat-insulation layer and outer metal level successively.
Described refrigerant layer, sealing is filled with refrigerant.Described freezing liquid can be that salt solution, natural liquid amino acid freezing liquid or other can reach the liquid of freezing heat insulation effect.
The material of described heat-insulation layer is cork, plastics or foam cotton.
The material of described inner metal layer, intermediate metal layer and outer metal level is stainless steel, preferably medical stainless steel.
The utility model is equipped with dismountable alignment pin between upper box and lower box, can, according to the number of stored food, select different casing quantity.After alignment pin is installed, the casing that can add up, the capacity of increase storeroom, after the dismounting alignment pin, can reduce casing, reduces the capacity of storeroom.
