Abstract

The invention belongs to the technical field of logistics transportation packing boxes, and particularly relates to a packing box for frozen food logistics transportation. The packing box comprises anouter box body and an inner box body. The inner box body is connected with the inner wall of the outer box body by springs. An outer box cover is arranged on the outer box body. An inner box cover isarranged on the inner box body. An annular sliding groove is formed in the inner wall of the inner box body. A first piston plate is slidably mounted in the sliding groove. Dry ice is mounted in a cavity below the first piston plate. Two air cylinders are symmetrically arranged on the outer wall of the inner box body in a left and right mode. A cavity on the first piston plate communicates with the air cylinders by pipelines. Piston rods of the air cylinders drive racks in the inner box body to move. Two second connecting rods are symmetrically hinged to the lower surface of the first pistonplate in a left and right mode. Gears are fixedly connected to the lower ends of the second connecting rods. The gears are engaged with the racks. Cold air bags wrapped in elastic materials are arranged on the upper half part of the inner box body. The cold air bags communicate with the cavity below the first piston plate by pipelines. The pipelines are internally provided with one-way valves usedfor feeding air into the cold air bags unidirectionally.

Description

technical field [0001] The invention belongs to the technical field of logistics transportation packaging boxes, in particular to a frozen food logistics transportation packaging box. Background technique [0002] With the widespread rise of the logistics and transportation industry, various items will be delivered through logistics and transportation. However, the long-distance transportation of frozen foods has always been a very troublesome problem. Big loss, but the existing technology can't refrigerate and keep the frozen food well during the long-distance transportation, and at the same time can't avoid the collision of the frozen food during the transportation. The quality will not change. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the present invention proposes a frozen food logistics transport packaging box, which is mainly used to solve the problem that frozen food cannot be well refrigerated and kept fresh duri...
