Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics, in particular to a cold chain logistics box which is easy to open and close. Background Art

[0002] Cold chain logistics refers to the process of storing and transporting food by refrigeration and freezing, including quick-frozen food, poultry, meat, aquatic products, etc., as well as specific medicines and medical organs. For such items that require cold chain logistics transportation, they are generally stored and transported in specific logistics boxes, which can improve the insulation effect while also having a protective effect;

[0003] For example, the cold chain logistics box disclosed in publication number CN117246642A has an insulation layer bonded to the inner surface of the box, which can reduce the loss of cold air in the box. The two-way hydraulic cylinder drives the two connecting blocks to extend, and the supporting arms are used to support the legs rotatably connected to the box, so that the legs can be placed vertically, that is, the universal wheels replace the storage inner box to contact the ground, which is convenient for workers to rely on the mobility of the universal wheels to push and transfer the storage inner box on the ground with less effort;

[0004] However, the above-mentioned cold chain logistics box still has the following problems during actual use: although the door is opened by driving the swing arm, this type of door needs to be locked by a motor when protecting the logistics box. The self-locking effect of the door requires the motor to be equipped with a power supply, which causes additional energy loss. At the same time, the logistics boxes cannot be stacked during transportation, which seriously occupies the car area and cannot improve the efficiency of cold chain logistics.

[0005] Therefore, we propose a cold chain logistics box that is easy to open and close in order to solve the above-mentioned problems. Utility Model Content
