Storage box

Abstract

The invention discloses a storage box, and relates to the technical field of cold chain storage devices. The storage box comprises a box body and threaded rods. A U-shaped groove is formed in the bottom of the box body, and a cover plate is installed on the bottom surface of the U-shaped groove. The two threaded rods are installed in two vertical groove bodies of the U-shaped groove respectively, and the two installed threaded rods are parallel to each other. A plurality of air storage parts sleeve the threaded rods, the air storage parts are located in the U-shaped groove, and the air storage parts communicate with the interior of the box body through air holes formed in the side face of the U-shaped groove. Two first connecting rods are rotationally installed at the bottom of the U-shaped groove, the ends, close to each other, of the two first connecting rods are rotationally connected, and the other end of each first connecting rod is rotationally connected with the end of the corresponding threaded rod through a second connecting rod. According to the storage box, a third connecting rod drives the connected threaded rods to move upwards, the threaded rods which move upwards drive a mounted first disc body to move upwards, and therefore a cavity between the first disc body and a second disc body is enlarged, the cold air inside the box body is sucked into the cavity to be temporarily stored, and the loss of the cold air is reduced.

Description

technical field [0001] The invention belongs to the technical field of cold chain storage devices, in particular to a storage box. Background technique [0002] Cold chain logistics is always in a prescribed low temperature environment in all links from production, storage, transportation, sales, to consumption, to ensure product quality is a systematic project. In addition, such as medical drugs, reagents, blood samples, etc. Items transported under low temperature conditions. Cold chain logistics is established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on refrigeration technology and using refrigeration technology as a means. The requirements of cold chain logistics are relatively high, and the corresponding management and capital investment are also larger than ordinary room temperature logistics. During the use of the existing low-temperature storage box, because the i...

Problems solved by technology

During the use of the existing low-temperature storage box, because the items stored in the low-temperature storage box are taken, a large amount of cold air is lost, which easily leads to the rapid consumption of the cold source, and cannot achieve long-term storage
