[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1 and Figure 2The utility model is a low-temperature refrigerated storage device for reagent transportation, comprising a heat preservation box 1 and a sealed flap 2 arranged on the outer wall on one side of the top port of the heat preservation box 1. The heat preservation box 1 is a square structure, and handles are fixedly connected to the side walls at both ends of the heat preservation box 1. The sealed flap 2 is movably connected to the outer wall on one side of the top port of the heat preservation box 1 through a hinge. A display 21 is embedded on the outer wall at the middle of the top of the sealed flap 2. A temperature sensor 22 is fixedly connected to the lower end of the top plate of the sealed flap 2. The temperature sensor 22 is electrically connected to the display 21. The temperature sensor 22 detects the internal temperature of the heat preservation box 1 in real time and transmits the data to the display 21 for display, so as to monitor the storage temperature of the reagent in the heat preservation box 1 in real time.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] In order to solve the problem that the reagent bottles are placed directly in the existing storage device, and the reagent bottles are easily damaged due to severe vibration after contacting the box, resulting in reagent leakage, please refer to Figure 1-Figure 3 , provide the following preferred technical solutions:

[0026] The inner walls of both sides of the heat preservation box 1 are evenly spaced and fixedly connected with suspension components 3, and the suspension components 3 are used to movably clamp the refrigeration cylinder 4, and the medicine bottles storing reagents are placed in the refrigeration cylinder 4;

[0027] The suspension assembly 3 includes a limit collar 31, and a limit groove 5 is arranged on the outer wall of the refrigeration cylinder 4. The limit groove 5 matches the limit collar 31. The refrigeration cylinder 4 is suspended and fixed by the limit collar 31 through the limit groove 5. The inner cavity of the limit collar 31 is movable to the refrigeration cylinder 4. A connecting belt 32 is fixedly connected between the side walls of the adjacent limit collars 31. The limit collar 31 and the connecting belt 32 are preferably made of fabric material and are connected and fixed to each other by sewing. The side walls of the two outermost limit collars 31 are A clamping plate 33 is fixedly connected to the side wall at the end of the upper connecting belt 32. The clamping plate 33 is made of metal. A positioning screw 34 is provided on the side wall at the middle of the clamping plate 33. After the clamping plate 33 is attached to the inner wall of the insulation box 1, the end of the connecting belt 32 is pressed into an L shape to increase the fixing stability of the end of the connecting belt 32. The positioning screw 34 passes through the clamping plate 33 and is inserted into the inner wall of the insulation box 1 to suspend and limit the connecting belt 32 and the inner wall of the insulation box 1, so as to facilitate the disassembly and replacement of the limit clamp ring 31.

[0028] Specifically, after a certain number of limiting collars 31 are placed side by side, a corresponding number of refrigeration cylinders 4 are respectively assembled with all the limiting collars 31 by means of sleeves, and the limiting collars 31 are sequentially connected end to end by means of connecting belts 32, so that the limiting collars 31 are arranged side by side to form a belt chain, and after the positioning screws 34 pass through the compression plates 33 at the ends of the connecting belts 32 on the side walls of the limiting collars 31 at the ends of the belt chain, the ends of the positioning screws 34 are screwed into the inner wall of the heat preservation box 1, so that the limiting collars 31 and the refrigeration cylinders 4 are sequentially suspended side by side at uniform intervals inside the heat preservation box 1, so that The refrigeration cylinder 4 does not come into direct contact with any inner wall of the insulation box 1. After the glass bottle containing the reagent is placed inside the refrigeration cylinder 4, the bottom of the refrigeration cylinder 4 does not touch the bottom plate of the insulation box 1. When the insulation box 1 generates severe vibration during transportation, the vibration only causes the stretched connecting belt 32 to slightly swing up and down. The suspended connecting belt 32 buffers and absorbs the vibration. When the refrigeration cylinder 4 swings up and down with the connecting belt 32, its bottom plate does not contact the bottom plate of the insulation box 1, thereby avoiding the problem of reagent leakage due to the breakage of the reagent bottle inside the refrigeration cylinder 4 due to severe vibration. It is convenient and practical.

[0029] For better low temperature refrigeration of reagents, please refer to Figure 3-Figure 5 , this implementation provides the following technical solutions:

[0030] The refrigeration cylinder 4 includes an intermediate sleeve 41 which is movably inserted into the limiting collar 31. The upper and lower ends of the intermediate sleeve 41 are open, and an upper cover 42 and a lower cover 43 are movably threadedly sleeved on the outer walls of the upper and lower ends of the intermediate sleeve 41, respectively. A partition plate 44 is fixedly connected to the inner wall of the intermediate sleeve 41 near the bottom port, and connecting pipes 45 are evenly spaced on the partition plate 44. A refrigerated ice bag 46 is placed on the bottom plate of the lower cover 43.

[0031] The inner walls of the middle sleeve 41, the upper cover 42 and the lower cover 43 and the top of the partition plate 44 are all fixedly connected with an inert gas cushion 47. The inert gas cushion 47 on the top of the partition plate 44 is provided with a transfer hole for accommodating the wrapped connecting pipe 45. The outer wall of the inert gas cushion 47 is evenly and fixedly connected with elastic protrusions 48. The elastic protrusions 48 are hemispherical structures and are connected with the inert gas cushion 47.

[0032] The middle sleeve 41 includes a thermal insulation lining 411 and an outer insulation plate 412 coaxially wrapped and arranged outside the thermal insulation lining 411, an insulation gap 413 is arranged between the thermal insulation lining 411 and the outer insulation plate 412, and the insulation gap 413 is filled with vegetable oil 414. The composition structure of the middle sleeve 41 is the same as the composition structure of the upper cover 42 and the lower cover 43. By designing the middle sleeve 41, the upper cover 42 and the lower cover 43 to be a hollow double-layer structure, and filling the insulation gap 413 with vegetable oil 414, the low thermal conductivity of the vegetable oil 414 is utilized to further reduce the rate at which cold air generated by the refrigerated ice bag 46 inside the thermal insulation lining 411 is dissipated outward, thereby ensuring a good low-temperature refrigeration effect on the reagent.

[0033] Specifically, the middle sleeve 41, the upper cover 42 and the lower cover 43 are combined to form a closed storage space, and the reagent bottle is placed above the inert gas cushion 47 on the top of the partition pad 44 in the middle sleeve 41, and is clamped and fixed by the elastic protrusion 48. The inner walls of the middle sleeve 41, the upper cover 42 and the lower cover 43 and the inert gas cushion 47 and the elastic protrusion 48 on the top of the partition pad 44 act as a buffer isolation layer for the reagent bottle, which not only provides flexible buffering for the reagent bottle, but also uses the inert gas cushion 47 and the elastic protrusion 48 to insulate the reagent bottle and delay the outward emission of cold air from the refrigerated ice bag 46 on the bottom plate of the lower cover 43. Due to the spacing of the elastic protrusion 48, the cold air emitted by the refrigerated ice bag 46 flows through the connecting pipe 45 to the space above the partition pad 44, so that the cold air circulates fully and wraps the reagent bottle in all directions to enhance the low-temperature refrigeration effect of the reagent.
