[0001] The utility model relates to the technical field of kits, in particular to a purification kit. Background Art

[0002] Test kits are boxes used to hold chemical reagents for detecting chemical components, drug residues, virus types, etc. They are generally used in hospitals or pharmaceutical companies. The purpose of the production of test kits is to enable experimenters to get rid of the tedious reagent preparation and optimization process. Therefore, the test kits are generally equipped with corresponding instructions for use. Users can get satisfactory results with no or only a small amount of optimization according to the instructions.

[0003] Chinese patent publication number CN219296014U discloses a purification kit comprising an outer barrel, the bottom of the inner cavity of which is fixedly connected to a support frame, the top of which is fixedly connected to a horizontal plate, the interior of which is provided with a circular groove, and a rubber pad is clamped into the groove, and the bottom of the horizontal plate is fixedly connected to a test tube rack. When the purification kit needs to accommodate reagent tubes of different sizes, the spring supports the bottom plate, ensuring that the bottom plate always fits the bottom of the reagent tube, thereby lifting the reagent tube. This allows the technical solution to accommodate reagent tubes of different sizes, improving the practicality and protectiveness of the technical solution.

[0004] However, the above technical solution has the following problems: when storing reagents, they often need to be stored in a low-temperature environment. The device uses a motor to actuate the outside air to cool the internal reagent tubes, but the motor generates heat during operation, and the reagent tubes cannot be cooled in this way in hot weather. Utility Model Content

DETAILED DESCRIPTION

[0020] Example 1

[0021] like Figure 1-Figure 5 As shown, a purification kit proposed in this embodiment includes an outer cylinder 1, a clamping mechanism and a refrigeration component. The outer cylinder 1 is threadedly connected to a base frame 11 and a top cover 6. A placement tray 2 is also provided on the outer cylinder 1. A connecting rod 5 is detachably connected to the placement tray 2. A fixing nut 16 is threadedly connected to the connecting rod 5. The clamping mechanism includes a plurality of clamping components and a plurality of fixing components 4 arranged along a ring on the placement tray 2, and the plurality of clamping components and the plurality of fixing components are distributed in a one-to-one correspondence. The refrigeration component includes a driven rod 12 rotatably arranged on the base frame 11, a refrigeration tray 13 detachably arranged on the driven rod 12, a plurality of refrigeration racks 14 arranged along a ring on the refrigeration tray 13, and an elastic belt 15 provided on each of the plurality of refrigeration racks 14. The connecting rod 5 abuts against the driven rod 12. The connecting rod 5 includes a connecting rod portion 51 and a driving block portion 52 arranged at the bottom end of the connecting rod portion 51; the top of the driven rod 12 has a driven groove 121, and the driving block portion 52 is located at the driven groove 121. The cross-section of the driving block portion 52 and the driven groove 121 is rectangular, so that when the driving block portion 52 rotates, it drives the driven rod 12 to rotate synchronously.

[0022] When using this embodiment, the user places ice bags and a certain amount of ice water inside the base frame 11, then fixes the refrigeration tray 13 on the base frame 11, and seals the base frame 11 to prevent direct contact between the liquid and the test tube. The base frame 11 is threadedly connected to the outer tube 1, and the connecting rod 5 is abutted against the driven rod 12, so that multiple refrigeration racks 14 correspond one-to-one with multiple groups of clamping components. Subsequently, multiple groups of reagent tubes are fixed on the placement tray 2, and the bottom of the reagent tube is abutted against the elastic band 15. The elastic band 15 is also in a relaxed state when not in use, so as to prevent the elastic band 15 from exerting a reverse force on the bottom of the reagent tube, resulting in a poor cooling effect of the test kit. The cold water and ice bags will exchange heat with the reagent under the action of solid objects such as the elastic band 15 and the reagent tube, so as to keep the reagent in a low temperature state in real time, so as to prevent the reagent from being affected by the external high temperature environment and causing changes in its properties.

[0023] Example 2

[0024] like Figure 1-Figure 3 As shown, the purification kit proposed in this embodiment, compared to Example 1, has a closure cap 10 rotatably mounted on the top cover 6. The top cover 6 is provided with a drive assembly comprising a rotating post 7 slidably mounted on the top cover 6, a push ring 8 rotatably mounted on the rotating post 7, and a spring a9 disposed between the push ring 8 and the top cover 6. The connecting rod 5 abuts the rotating post 7. The bottom of the rotating post 7 has a drive groove 71, and the abutment point between the connecting rod 5 and the rotating post 7 is located at the drive groove 71. The closure cap 10 is made of transparent plastic and is sprayed with a transparent heat-insulating coating.

[0025] In this embodiment, when removing a reagent individually, the user presses the rotating column 7 downward according to the needs of the user, and rotates the rotating column 7 according to the position of the connecting rod 5 until the connecting rod 5 abuts against the driving groove 71. Then the rotating column 7 drives the connecting rod 5 to rotate, so that the reagent required by the user moves to the bottom of the closing cover 10. The closing cover 10 is rotated to allow the user to take out the reagent, thereby reducing the loss of cold air inside the test kit and improving the time for the test kit to ensure the quality of the reagent.

[0026] Example 3

[0027] like Figure 3 and Figure 4 As shown, a purification kit proposed in this embodiment, compared with Example 1, in this embodiment, the clamping assembly includes two groups of pushing assemblies 3 relatively arranged on the placement plate 2, and the pushing assembly 3 includes a plurality of driving rods 33 slidingly arranged on the placement plate 2, a clamping block 31 connected to the driving rod 33, an elastic block 32 arranged on the clamping block 31, a telescopic belt 34 arranged on the adjacent clamping block 31, and a spring c coaxially arranged on the driving rod 33.

[0028] When using this embodiment, the user places the reagent tube between the two pushing components 3, and then the reagent tube pushes the two groups of pushing components 3 away from each other through the elastic block 32. At the same time, the telescopic belt 34 will contact the outer peripheral surface of the reagent tube to increase the contact area between the clamping component and the reagent tube, and the spring c will ensure the clamping force of the pushing component 3 to prevent the reagent tube from moving at will.

[0029] Example 4

[0030] like Figure 3 and Figure 4 As shown, a purification kit proposed in this embodiment, compared with Example 1, in this embodiment, the fixing component 4 includes a plurality of fixing frames 41 arranged along a ring on the base frame 11, and a plurality of groups of matching clamping components arranged along a ring on each of the plurality of fixing frames 41; the matching clamping component includes a rotating plate 42 rotatably arranged on the fixing frame 41, a rubber block 43 arranged on the rotating plate 42, and a spring b44 whose two ends respectively connect the rotating plate 42 and the fixing frame 41.

[0031] When this embodiment is used, the reagent tube slides into contact with the multiple rubber blocks 43, and then the multiple springs b44 push the multiple rotating plates 42 to drive the multiple rubber blocks 43 to apply a certain pressure to the reagent tube, so that the reagent tube remains stable under the action of multiple pressures, thereby preventing the reagent tube from moving at will.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
