Description

A portable cold chain transport box assembly

technical field

The invention is a portable cold chain transport box assembly, relates to a cold chain transport box assembly used in logistics transportation of goods, belongs to the technical field of cold chain transport equipment, and particularly relates to a cold chain transport box assembly using dry ice as a refrigeration consumable , a combination of transport boxes that are convenient for refrigerated items.

Background technique

At present, the cold chain transport boxes used in the market are mainly made of expandable polystyrene foam, because of its light weight, non-toxicity, can be molded, cheap, low water absorption, low temperature resistance and other advantages , is widely used in logistics transportation, especially in cold chain transportation, but due to its insufficient hardness, it is mostly one-time use after repeated handling in logistics transportation, and the loss is serious. At present, in cold chain transportation, foam insulation is mostly used The method of adding ice cubes in the box is used for the transportation of fresh and other goods. In order to improve the freezing time of the items, the ice in the foam insulation box will be much larger than the number of items, which will increase the cost of the goods, and in order to better maintain the foam The freezing effect of the items in the incubator will often cause the items to directly contact with the ice cubes. When transporting food items, it is easy to form secondary pollution and affect people's health. Other incubators with refrigeration equipment also have costs. The shortcomings of high and poor refrigeration effect. In cold chain transportation, some food-grade dry ice is currently used as refrigeration consumables for incubators, but most of the dry ice is directly mixed with items and placed in the incubator, resulting in faster sublimation of dry ice and better refrigeration effect. Poor, and during transportation, due to the sublimation of dry ice, pores appear in the incubator, making the transported items easy to damage during transportation.

Contents of the invention

In order to solve the above problems, the present invention provides a portable cold chain transport box assembly that uses dry ice as a refrigeration consumable to facilitate the refrigeration of items. The structure is simple and easy to use, which can effectively prolong the refrigerated storage time of the cold chain transport box, prevent secondary pollution in the cold chain transport, and greatly reduce the cost of cold chain transport.

A portable cold chain transport box assembly of the present invention is realized in the following way: a portable cold chain transport box assembly of the present invention is composed of a handle placement groove, an upper sealing cover plate, a fixed cassette, a dry ice placement plate, a hollow bearing Composed of pallet, sealing card slot, sealing connection slot, fixing buckle, main body box, pressure-bearing base, connecting frame, connecting protrusion, dry ice storage frame, sealing protrusion, ventilation hole, limit hole and limit pin, The lower part of the main box is placed on a pressure-bearing base, and the upper part of the main box is provided with a connecting frame. The main box can be a multi-layer composite structure, preferably polypropylene, heat-insulating layer polyurethane foam, The pressure-bearing base is preferably made of polyurethane material, and the connecting frame can be made of expandable polystyrene foam or polyurethane material. The fixing buckle is placed on the connection frame, the sealing connection groove is placed on the connection frame, and the connection protrusion is placed around the bottom of the dry ice storage frame, and corresponds to the sealing connection groove on the connection frame. The connection protrusions may be formed by multiple protrusions or a single protrusion, and the sealing connection groove is provided according to the number of connection protrusions. The hollow support plate is placed on the inner wall of the connecting frame, four limit pins are placed at the four corners of the hollow support plate, and the sealed card slot is placed above the dry ice storage frame, and there are multiple ventilation holes on the dry ice storage plate , the diameter of the ventilation hole is 3mm-16mm. There are four limit holes at the four corners of the dry ice placing plate, and the limit holes on the dry ice placing plate correspond to the limit pins at the four corners of the hollow supporting plate. The handle placement groove is placed on the upper sealing cover plate, and a folding handle is built in the handle placement groove. The fixing cassette is placed on one side of the upper sealing cover. A buffer gasket is placed inside the upper sealing cover plate. The sealing protrusions are placed around the bottom of the upper sealing cover, and correspond to the sealing slots on the top of the dry ice storage frame. The sealing protrusion may be formed of multiple protrusions or a single protrusion, and the sealing groove is provided according to the number of sealing protrusions.

When in use, first put the items transported by the cold chain into the main box according to the needs, and then place the connection protrusion under the dry ice storage frame into the sealed connection groove on the connection frame, and the dry ice storage frame and the connection frame are airtightly connected , and then place the dry ice plate on the hollow support plate on the inner wall of the connecting frame, and insert the limit pin on the hollow support plate into the limit hole on the corresponding dry ice plate, which can effectively prevent the hollow support plate from When the position is moved when it is subjected to external bumps during transportation, place the prepared dry ice evenly on the dry ice storage plate, and then insert the sealing protrusion under the upper sealing cover into the sealing slot above the dry ice storage frame. The upper airtight cover plate and the dry ice storage frame are hermetically connected, and the buffer gasket inside the upper airtight cover plate can effectively prevent the dry ice from moving during transportation. Connect the fixed tape on one side of the upper sealing cover with the fixing buckle on the connecting frame, so that the upper sealing cover, the dry ice storage frame and the main box are connected as a whole, and the transported items are prevented from falling out during transportation . The handle placement groove is recessed into the upper sealing cover plate, which can make the cold chain transport box assembly easy to stack and transport during transportation. Concave-convex connections can be arranged above the upper sealing cover plate and below the pressure-bearing base according to transportation needs. The cylindrical dry ice placed on the dry ice storage board sublimates and absorbs heat, which makes the temperature in the dry ice storage frame drop rapidly. Through the ventilation holes on the dry ice storage board, it forms convection with the main box, and the temperature in the main box can be reduced. The temperature keeps dropping. When the dry ice is exhausted, you only need to add dry ice. During transportation, it can effectively reduce the weight of the box for ice transportation, and the refrigeration effect can be stored longer. The dry ice stored in a single dry ice box Quantity, which can extend the refrigeration effect in the main box to 5-7 days, which meets the storage of most short- and medium-distance cold chain transportation items at present. In order to improve the effect of cold chain transportation, during the long-distance cold chain transportation of goods, you can Place and stack multiple dry ice storage boxes to increase the dry ice storage capacity and improve the cooling effect. The dry ice storage boxes and the main box can also be mixed and stacked according to needs. The dry ice can be cylindrical dry ice or block dry ice to reduce The purpose of cold chain transportation cost.

Beneficial effect.
