[0043] The following will clearly describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments that can be obtained by a person of ordinary skill in the art without inventive effort are within the scope of protection of this application. It should be noted that the terms used in this description are intended solely to describe specific embodiments and are not intended to limit the exemplary embodiments of this application. For ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn to scale. Technologies, methods, and devices known to a person of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely illustrative and not limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] Example 1:

[0045] This embodiment provides an RNA kit, including a box body 1, and further comprising:

[0046] The sponge pad 2 has a through hole 18 formed in the middle thereof;

[0047] A mounting post 3 is fixedly arranged at the bottom of the box body 1, and the diameter of the mounting post 3 matches the through hole 18;

[0048] The pressing plate 4 is in the shape of a disk, and a stud 5 is fixedly provided at the lower end of the pressing plate 4. The diameter of the pressing plate 4 is larger than the diameter of the through hole 18;

[0049] A threaded hole 6 is provided on the mounting post 3;

[0050] When the sponge pad 2 is placed in the box body 1 , the mounting post 3 is located in the through hole 18 , the stud 5 is screwed in the threaded hole 6 of the mounting post 3 , and the lower surface of the pressure plate 4 contacts the upper surface of the sponge pad 2 .

[0051] In this technical solution, the sponge pad 2 is used to place the reagent tube, which is not limited to the sponge pad 2, but can also be other materials with elastic deformation ability and heat preservation ability.

[0052] In the past, the sponge pad 2 was fixed in the box body 1 by glue. If it aged after long-term use, it would affect the placement of the reagent tube. If the sponge pad 2 was forcibly torn off, glue marks would be left. In addition, the new sponge pad 2 needed to be fixedly connected to the box body 1 with additional glue, which was more troublesome.

[0053] In this embodiment, when the sponge pad 2 needs to be replaced, the through hole 18 of the sponge pad 2 is inserted toward the mounting post 3 of the box body 1, thereby placing the sponge pad 2 in the box body 1. At this time, the mounting post 3 is located in the through hole 18. It should be noted that the upper surface of the mounting post 3 can be lower than the upper surface of the sponge pad 2. This arrangement allows the pressure plate 4 to have a downward movement margin, which better fixes the sponge pad 2.

[0054] The upper surface of the mounting post 3 may also be equal to the upper surface of the sponge pad 2, but the upper surface of the mounting post 3 will not be higher than the upper surface of the sponge pad 2;

[0055] After the sponge pad 2 is placed in the box body 1, the stud 5 of the pressing plate 4 is screwed into the threaded hole 6 of the mounting column 3, and the pressing plate 4 moves downward due to the thread transmission;

[0056] The stud 5 is driven to rotate by rotating the pressing plate 4. At this time, the outer circumferential surface of the pressing plate 4 may have anti-slip textures, which are used to provide a certain degree of friction when rotating the pressing plate 4, so as to save effort.

[0057] After the pressure plate 4 moves downward due to the threaded transmission, its lower surface will come into contact with the upper surface of the sponge pad 2. Then, the pressure plate 4 is slightly tightened so that the pressure plate 4 is pressed against the upper surface of the sponge pad 2. The sponge pad 2 can be limited by the cooperation between the lower surface of the pressure plate 4 and the bottom of the box body 1, thereby fixing the sponge pad 2.

[0058] When the sponge pad 2 needs to be replaced, on the contrary, the pressing plate 4 is dismantled, the sponge pad 2 is removed, and a new sponge pad 2 is replaced.

[0059] Through this structural design, by setting up the installation column 3 and the pressure plate 4, the sponge pad 2 can be easily fixed, so that when the sponge pad 2 needs to be replaced, there is no need to tear it off forcibly, and there is no need to purchase additional glue for matching, making the overall replacement of the sponge pad 2 more convenient.

[0060] Example 2:

[0061] This embodiment provides an RNA kit, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] Furthermore, it also includes:

[0063] Positioning plates 7: a plurality of positioning plates 7 are formed on the inner wall of the box body 1;

[0064] When the sponge pad 2 is placed in the box body 1 , the lower surface of the positioning plate 7 contacts the upper surface of the sponge pad 2 .

[0065] In this technical solution, when the sponge pad 2 is not fixed by the pressing plate 4, during the process of installing the sponge pad 2, the sponge pad 2 can be installed under the positioning plate 7 by virtue of its elastic deformation ability. The positioning plate 7 is a small plate-shaped protrusion, thereby positioning the position of the sponge pad 2;

[0066] After the sponge pad 2 is fixed by the pressing plate 4, the positioning plate 7 can position the outer ring of the sponge pad 2, while the pressing plate 4 positions the middle part of the sponge pad 2, making the overall positioning more stable.

[0067] Through this structural design, by setting up the positioning plate 7, a positioning effect is achieved when the sponge pad 2 is installed. At the same time, after the sponge pad 2 is fixed, the positioning effect continues to be achieved on the outer ring of the sponge pad 2, and cooperates with the pressure plate 4 to make the whole more stable.

[0068] Example 3:

[0069] This embodiment provides an RNA kit, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] Furthermore, it also includes:

[0071] The box cover 8 is used to cover the box body 1. The box cover 8 includes a rotating part 9 and a buckling part 10. The buckling part 10 is annular and is used to be buckled and connected with the box body 1. The rotating part 9 is a disk, which is rotatably arranged on the inner circle of the buckling part 10.

[0072] The sponge pad 2 is provided with a plurality of sockets 11 for storing reagent tubes;

[0073] an opening 12 formed on the rotating portion 9 of the cover 8;

[0075] The opening 12 will correspond to the insertion holes 11 at different positions as the rotating part 9 rotates.

[0076] In this technical solution, the reagent tube is stored in the sponge pad 2 through the insertion hole 11, and the box cover 8 covers the box body 1 to prevent foreign matter from entering. Since the box cover 8 and the box body 1 are snap-fitted, when the force is applied to open it, if the force is not controlled well, a certain vibration will be generated, which will affect the reagent tube.

[0077] At the same time, if the box cover 8 is opened as a whole when taking out the reagent tube, the open area of ​​the box body 1 will be too large, and foreign matter may creep into the box body 1 without being noticed, causing damage to the reagent tube;

[0078] In order to avoid affecting the reagent tubes, the box cover 8 is divided into a rotating part 9 and a buckling part 10. The rotating part 9 has an opening 12, which corresponds to the insertion holes 11 at different positions as the rotating part 9 rotates;

[0079] When the reagent tube in the insertion hole 11 needs to be taken out, the rotating part 9 is rotated so that the opening 12 corresponds to the position of the reagent tube to be taken out, and then the reagent tube can be directly taken out.

[0080] Through this structural design, the box cover 8 is divided into a rotating part 9 and a buckling part 10, and an opening 12 is provided on the rotating part 9. The reagent tube in the box body 1 can be taken out through the opening 12 without opening the box cover 8, making it convenient and quick to take out the reagent tube and avoiding accidents.

[0092] Through this structural design, a pressure ring 15 is provided, and a gap is formed between the lower surface of the pressure ring 15 and the upper surface of the rotating part 9.
