Vehicle-mounted fresh-keeping and refrigerating container structure

Abstract

The invention relates to the technical field of refrigerating containers, and discloses a vehicle-mounted fresh-keeping and refrigerating container structure. The vehicle-mounted fresh-keeping and refrigerating container structure comprises an outer container and an inner container, wherein a heat insulation layer is arranged between the outer container and the inner container; a cover is arranged at the opened end of the outer container; a heat conducting plate is arranged at a bottom plate of the inner container; a freezing chamber is formed between the heat conducting plate and the bottom part of the inner container; a flat cold storing tank is arranged in the freezing chamber; liquid carbon dioxide fills the cold storing tank; a cold storing pipe is connected with the inner container through an exhausting pipe; a vertical liquid storing pipe is arranged at the inner wall of the left side of the inner container; hydrargyrum is stored in the liquid storing pipe; a slide sleeve in which a piston capable of being lifted up and down is arranged is fixed to the lower end of the liquid storing pipe; a propping rod is fixed to the lower end of the piston; a mechanical valve on which a valve rod is mounted is arranged at a position, on the lower end of the slide sleeve, of the exhausting pipe; a returning spring is arranged at the lower end of the valve rod, and the upper end of the valve rod is propped to the slide sleeve; a pressure limiting valve is arranged on the cover. The vehicle-mounted fresh-keeping and refrigerating container structure is capable of automatically adjusting and keeping the inner container in a low-temperature environment without electricity consumption, so that the product storing time, such as the meat product storing time, can be prolonged.

Description

technical field [0001] The invention relates to the technical field of storage boxes, in particular to a vehicle-mounted fresh-keeping refrigerator structure. Background technique [0002] At present, with the rapid popularity and development of online shopping, more and more people adopt online shopping. Online shopping has many advantages such as convenience, speed, and no need to go out, and is deeply loved by people. Corresponding to online shopping is logistics, especially long-distance logistics. At present, the transportation and storage of some fruits and vegetables, meat, fish and shrimp products are limited by time and temperature. For example, the transportation of some meat, fish and shrimp requires a low temperature environment to maintain Freshness, after online shopping, it needs to be transported by refrigerated logistics vehicle. The current refrigerated logistics vehicle has the internal refrigeration box and the body fixed, and it is large in size, heavy i...
