Portable refrigeration box for cold-chain logistics

Abstract

The invention discloses a portable refrigeration box for cold-chain logistics. The portable refrigeration box comprises a box body and a box cover; the box cover is located at the top of the box bodyand connected with the box body in a clamped mode, and a plurality of movable wheels are arranged at the bottom of the box body; the lower part in the box body is provided with a supporting plate slidably connected with the inner wall of the box body, and a cooling liquid bag is arranged at the inner bottom of the box body; the side face of the cooling liquid bag is connected with a supplementingpipe, and the front end of the supplementing pipe stretches out of the side face of the box body; and a connecting hole is formed in the cooling liquid bag. When materials are placed in the portable refrigeration box, the supporting plate can rotate relative to a rotary adjusting rod to slide along the inner wall of the box body through rotation of the rotary adjusting rod, the height of the supporting plate is adjusted, thus the distance between the materials and the box cover is adjusted, in the long-distance transport process, collision between the materials and damage caused by collision between the materials and the interior of the box body during occurrence of shaking are avoided, the adaptability of the portable refrigeration box is improved, the refrigeration effect is ensured through the height-adjustable cooling liquid bag, and safe refrigeration of the materials during long-distance transport is ensured.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a portable refrigerator used for cold chain logistics. Background technique [0002] Cold chain logistics refers to a systematic project in which frozen and refrigerated items are always in the specified low temperature environment in all links from production, storage, transportation, sales to consumption, so as to ensure the quality of items and reduce item loss; cold chain logistics It is suitable for the fields of primary agricultural products, processed food and special commodities such as medicines. [0003] Chinese Patent Authorization Announcement No. CN203889307U proposes a portable refrigerator for cold chain logistics, which continuously records the time-temperature change history of refrigerated food through the migration length of the indicator on diffusion and re-lifting, and provides information to managers or consumers.

[0003] Chinese Patent Authorization Announcement No. CN203889307U proposes a portable refrigerator for cold chain logistics, which continuously records the time-temperature change history of refrigerated food through the migration length of the indicator on diffusion and re-lifting, and provides information to managers or consumers. The signal of the quality status of refrigerated food is to indicate the remaining shelf life of refrigerated food, so as to meet the needs of real-time monitoring of quality changes of different varieties of refrigerated food during storage and logistics. However, due to the long-distance and long-term transportation of cold chain transportation, currently Most of the refrigerated boxes are designed with a fixed internal space. When different materials are loaded, they cannot be guaranteed to match. As a result, if bumps occur during transportation, it will cause collisions between materials and materials, materials and boxes, and may cause damage to materials.
