[0002] In nucleic acid extraction and purification experiments, comparative analysis of samples is often required, necessitating the use of compartmentalized reagent kits with robust control capabilities. However, existing compartmentalized kits often lack stable connection structures for comparison, leading to loosening after kit assembly and affecting the accuracy of experimental results. Furthermore, the design for fixing and dispensing reagent tubes is inadequate, hindering efficient comparison of different tubes and limiting compatibility with various tube diameters, thus restricting their application and causing numerous inconveniences in experimental operations. Therefore, a compartmentalized reagent kit for nucleic acid extraction and purification is proposed to address these issues. Utility Model Content

[0003] This invention proposes a compartmentalized reagent kit for nucleic acid extraction and purification. By using the splicing of inserts and slots, as well as structures such as limiting blocks and limiting columns, it solves the problems of insufficient stability and inconvenient splicing and disassembly of compartmentalized reagent kits during comparison.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0023] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each figure, and they do not represent the reagent structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Refer to the instruction manual appendix Figure 1-5A separate reagent kit for nucleic acid extraction and purification includes a separate reagent kit body 1, with a plug 2 fixedly connected to one end of the separate reagent kit body 1 and a slot 3 opened at the other end. The separate reagent kit body 1 and the plug 2 are connected and fixed by plugging the plug 2 into the slot 3. A first limiting block 4 is fixedly connected to one end of the separate reagent kit body 1, and a second limiting block 5 is fixedly connected to the other end of the separate reagent kit body 1. The separate reagent kit body 1 and another separate reagent kit body 1 are installed by snapping the first limiting block 4 into the second limiting block 5. Through the above structure, two sets of separate reagent kit bodies 1 can achieve the effect of combined installation by splicing the plug 2 and the slot 3, thereby facilitating comparative control experiments on two sets of separate reagent kit bodies 1 and solving the problem of the separate reagent kit body 1 not having a stable effect when compared.

[0027] Then, a limiting post 7 is moved inside the first limiting block 4, and a limiting groove 8 is opened on the second limiting block 5. The limiting post 7 passes through the moving groove 6 and is inserted and fixed inside the limiting groove 8. Through the above operation, the insertion of the second limiting block 5 by the first limiting block 4 and the insertion and fixing of the limiting groove 8 by the limiting post 7 achieves the effect of splicing and fixing the compartmentalized reagent kit body 1 with another compartmentalized reagent kit body 1.

[0028] Subsequently, a first spring 9 is provided inside the moving groove 6. One end of the first spring 9 is fixedly connected to the limiting post 7, and the other end of the first spring 9 is fixedly connected to the moving groove 6. Through the above structure, pressing the limiting post 7 causes the limiting post 7 to disengage from the limiting groove 8, thereby releasing the fixed connection between the second limiting block 5 and the first limiting block 4, thus achieving the disassembly effect. Conversely, the elasticity of the first spring 9 is used to drive the limiting post 7 to reset, achieving the effect of the limiting post 7 being inserted into the limiting post 78, thus achieving the purpose of normal use of the equipment.

[0029] Next, the outer wall of the limiting post 7 fits into the inner wall of the limiting groove 8, and the positions of the moving groove 6 and the limiting groove 8 correspond to each other. Through this mechanism, when the limiting post 7 is inserted into the limiting groove 8, it achieves a fixed effect, thereby enabling the normal use of the equipment.

[0030] At this time, an array of reagent tubes 10 are inserted into the body 1 of the compartmentalized reagent kit. A clamping plate 11 is provided on the outside of the reagent tubes 10. A clamping block 12 is fixedly connected to the clamping plate 11. A fixing block 13 is fixedly connected to the side of the clamping plate 11. An auxiliary block 14 is fixedly connected to one end of the fixing block 13. A moving rod 15 is slidably connected inside the auxiliary block 14. With the above structure, the reagent tubes 10 can be removed by clamping them with the clamping plate 11, which facilitates comparison of reagent tubes 10 arranged in the same horizontal direction and improves experimental efficiency.

[0031] Next, the clamping block 12 is arranged in an arc shape, and the clamping block 12 fits against the outer wall of the reagent tube 10. The inner wall of the clamping block 12 is provided with anti-slip texture; this increases the friction of the clamping plate 11 on the reagent tube 10, making the clamping plate 11 clamp the reagent tube 10 more stably.

[0032] Secondly, a second spring 16 is provided inside the auxiliary block 14. One end of the second spring 16 is fixedly connected to the moving rod 15, and the other end of the second spring 16 is fixedly connected inside the auxiliary block 14. The elastic properties of the second spring 16 drive the two sets of auxiliary blocks 14 and fixed blocks 13 to slide outward on the moving rod 15, thereby making the clamping block 12 applicable to reagent tubes 10 of different diameters and improving the applicability of the equipment.

[0033] Finally, the clamp 12 has the same number of lateral reagent tubes 10 as the number of reagent tubes 10 on the compartmentalized reagent kit body 1, and they correspond to each other inside the clamp 11; the above structure ensures that the number and position of the clamp 11 and the reagent tubes 10 correspond and fit together, thus ensuring the normal operation of the equipment.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
