2results about How to "Storage impact" patented technology

This invention provides a test tube storage device, belonging to the field of test tube storage technology. It includes a storage box, with a storage cover rotatably connected to one side of the upper surface of the storage box. A storage base plate, test tube rack, fixing components, a cooling plate, and a cooling fan are inserted into the lower surface of the storage box. This invention utilizes a design where a desiccant packet is placed inside the heat dissipation base after the heat dissipation cover is opened. The desiccant packet absorbs water, reducing condensation from the cooling element flowing into the heat dissipation base and outwards. The heat dissipation element dissipates heat from the cooling element, and the cooling fan draws heat from the cooling element into the heat dissipation base and expels it outside. The cooling element cools one end, and the cooling fan draws air from the storage box into the top of the cooling element for further cooling. The cold air is then expelled from the outlet into the storage box, further cooling it. This method preserves samples stored in test tubes within the storage box, slowing down sample metabolism and degradation, effectively inhibiting microbial growth and reproduction, and extending sample preservation time.

The utility model relates to the technical field of refrigerators, in particular to a refrigerator shelf and a refrigerator. The refrigerator shelf comprises a rotating shelf, a supporting arm and a rotating assembly, the supporting arm is used for being installed on a refrigerator body of the refrigerator, and the supporting arm extends in the first direction; the rotating assembly comprises a connecting rod, a rotating gear and a fixed gear, one end of the connecting rod is fixed to the rotating shelf, the other end extends in the second direction, the rotating gear is arranged on the connecting rod, and the fixed gear is connected with the end, away from the box, of the supporting arm; the side face, facing the rotating gear, of the fixed gear is provided with a plurality of first teeth, the side face, opposite to the rotating gear, of the fixed gear is provided with a plurality of second teeth, a tooth groove is formed between each first tooth and two adjacent first teeth, and the second teeth are meshed with the tooth grooves. The first direction is perpendicular to the second direction. Thus, through meshing fit between the second teeth and the tooth grooves, the rotating speed of the rotating shelf is controllable, and therefore the situation that articles are thrown out due to the fact that the rotating speed of the rotating shelf is too high is avoided.
