[0002] In existing in vitro diagnostic equipment such as fully automatic coagulation analyzers, reagents need to be added to the sample for reaction. In order to ensure that the reagents do not deteriorate during use and to prevent the reagents from evaporating, a refrigeration chamber is generally set up in the equipment to store the reagents at low temperatures. An openable chamber cover is set up on the top of the refrigeration chamber. Except for replacing the reagent bottles, it is closed to reduce heat exchange. When adding or replacing the reagent bottles, the chamber cover needs to be lifted. During this process, the refrigeration chamber is in a fully open state, and the heat exchange area with the external environment is large, which can easily cause temperature fluctuations inside the refrigeration chamber, which is not conducive to the preservation of reagents; the removed chamber cover also requires additional storage space, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] The utility model provides Figures 1 to 4 A flip-top refrigeration warehouse shown includes a warehouse body 10 and a warehouse cover that closes the warehouse body 10. A reagent bottle positioning member and a rotating mechanism thereof are provided inside the warehouse body 10, and reference may be made to the relevant art. The warehouse cover includes a warehouse cover support member 20 and a warehouse cover flip member 30. The warehouse cover support member 20 is detachably connected to the warehouse body 10, and the warehouse cover flip member 30 is hinged to the warehouse cover support member 20 through a flip device 40. The warehouse body 10 can be opened or closed by changing the angle between the warehouse cover support member and the flip member.

[0025] In this embodiment, the bin cover support member 20 and the bin cover flip member 30 both include a shell 21, a support plate 22 and a heat-insulating layer 23 connected in sequence; the shell 21 is used to beautify the appearance of the bin cover and can be made of plastic; the support plate 22 is used to bear the load and can be made of metal; the heat-insulating layer 23 is arranged on the side of the support plate 22 facing the inside of the bin body, and is used to enhance the heat-insulating performance, and can be made of a heat-insulating film. The edge of the shell 21 is also provided with a flange extending toward the bin body 10 to play a positioning role. The bin cover support member 20 and the bin cover flip member 30 are both provided with a plurality of liquid extraction ports 24, and the liquid aspiration needle of the in vitro detection equipment is inserted into the bin body from the liquid extraction port 24 to facilitate the aspiration of reagents.

[0026] The bin cover flipping member 30 is also provided with a slider seat 31, and the slider seat 31 is provided with a reagent bottle replacement slot 32 connected to the interior of the bin body 10, and the reagent bottle replacement slot 32 is closed or opened by a cover plate 33 slidably connected to the slider seat 31. During normal operation, the bin cover flipping member 30 closes the bin body. When it is necessary to replace or add reagents, it is only necessary to cut open the cover plate 33 to open the reagent bottle replacement slot 32. Its cross-sectional area is extremely small compared with the bin cover, which reduces the heat exchange efficiency and has little effect on the temperature inside the bin body when it is opened; when it is necessary to inspect and maintain the internal structure of the bin body, the bin cover flipping member is opened or the bin body support member is removed.

[0027] Furthermore, the slider seat 31 is provided with a permanent magnet, and the cover plate 33 is provided with a magnetic attraction member 36 corresponding to the permanent magnet. After the cover plate 33 closes the reagent bottle replacement slot 32, the cover plate 33 is fixed by the magnetic force between the permanent magnet and the magnetic attraction member 36 to prevent vibration and other factors from opening the reagent bottle replacement slot 32. The bin cover flip member 30 and the cover plate 33 are both provided with handles 37 for easy operation.

[0028] The flip device 40 includes a flip support 41 disposed on the bin cover support 20 and a flip part 42 disposed on the bin cover flip part 30, wherein the flip part 42 is rotatably connected to the flip support 41. The flip device 40 also includes a torsion spring support shaft 43 disposed between the two flip supports 41, wherein the torsion spring support shaft 43 is provided with at least one annular groove, wherein the torsion spring is sleeved in the annular groove, wherein one end of the torsion spring is connected to the flip part 42, and the other end is connected to the torsion spring fixing member 44 disposed on the bin cover support 20. A female lock buckle 11 is disposed on the outer wall of the bin body 10, and a male lock buckle 34 corresponding to the female lock buckle 11 is disposed on the bin cover flip part 30, and the female lock buckle 11 and the male lock buckle 34 may refer to the relevant technology. When the male and female lock buckles are locked, they can overcome the elastic force of the torsion spring so that the bin cover flip part 30 closes the bin body; after the male and female lock buckles are opened, the torsion spring is reset, and the bin cover flip part 30 is automatically opened, which is convenient for operation.

[0029] Preferably, the bin body 10 is further provided with a proximity sensor 12, and the bin cover flip member 30 is provided with a sensing member 35 corresponding to the proximity sensor. The proximity sensor 12 is a photoelectric sensor, which is used to detect whether the bin cover flip member 30 closes the bin body.

[0030] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
