Description

Technical Field

[0001] This utility model relates to the field of virus reagent technology, specifically to a virus purification kit. Background Technology

[0002] Feline panleukopenia virus (FPV) is a highly infectious and fatal virus in felines, belonging to the Parvoviridae family, and is closely related to canine parvovirus (CPV-2). Its purification process requires optimization based on viral characteristics (such as non-enveloped, acid and heat resistant, and a single-stranded DNA genome). The purified nucleic acid sample is stored in a reagent tube, which needs to be stored within the reagent kit for convenient preservation and transportation.

[0003] Current reagent kits typically store reagent tubes by inserting the application tubes into the test tube sockets of the reagent rack. During handling or transportation, the reagent tubes are prone to shaking and bouncing, which can cause the tube caps to open, resulting in the leakage of viruses from the reagent tubes and causing serious contamination. Furthermore, when the test tube rack is full of test tubes, the large number of tubes can easily lead to confusion. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a virus purification kit that can press and position the reagent tubes, press the tube caps to prevent exposure, and group the reagent tubes, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a virus purification reagent kit, comprising a base plate and multiple frames, wherein each frame is slidably mounted on the base plate, and each frame has multiple top grooves at the end away from the base plate. A fixing seat is installed inside each frame, and the fixing seats are all located away from the top grooves. Each fixing seat has a bottom groove. Reagent tubes are provided in the vertically opposite top and bottom grooves. A limiting shell is installed outside each frame located in the top groove. The inner ring of the limiting shell is recessed to form a limiting groove. The outer ring of the tube cap on the reagent tube is inserted into the limiting groove, and the outer end face of the tube cap abuts against the inner wall surface of the limiting shell. Each frame can be detachably mounted with a pressure plate to press and position multiple reagent tubes.

[0006] As a preferred technical solution, the virus purification kit is characterized in that: both ends of the frame are equipped with connecting seats, and the end face of the connecting seat facing the pressure plate is provided with a positioning groove. One end of the positioning groove is enlarged to form an inlet / outlet groove communicating with the outside. Positioning blocks are installed on the inner side of the pressure plate opposite to the positioning groove, and the positioning blocks are inserted into the positioning groove.

[0007] As a preferred technical solution, each pressure plate has a positioning block of different lengths. Each side of the inner wall of the slot has a groove, and each groove has a positioning plate. One end of each positioning plate extends to the outside and abuts against the end face of the corresponding positioning block. The other end of each positioning plate is inserted into the groove and is equipped with a compression spring. The other end of each compression spring is installed on the inner wall of the groove.

[0008] As a preferred technical solution, the end of the positioning block away from the inlet / outlet groove is set to abut against the positioning groove, and the cross-sections of both the positioning block and the positioning groove are set in a trapezoidal structure.

[0009] As a preferred technical solution, the base plate is provided with multiple connecting slots, and a display rack is installed on one side of the frame. The display racks are all slidably set in the connecting slots. The connecting slots are all set in a trapezoidal structure, while the display racks are all set in a figure-eight structure.

[0010] As a preferred technical solution, the vertical cross-section of the frame is designed with a "U" shape.

[0011] As a preferred technical solution, the inner diameters of both the top and bottom grooves are matched with the diameter of the reagent tube.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, and the frames are all independently installed on the base plate, so that one frame is a group, which can distinguish the reagent tubes. The frames can be removed and placed independently, which greatly reduces the probability of confusion. The limiting shell can press and position the reagent tubes from top to bottom, and can also press down the tube caps to prevent them from being exposed when opened. The pressure plate can radially position the test tubes to prevent them from tipping over and increase stability. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a virus purification reagent kit of this utility model includes a base plate 1 and multiple frames 2. The frames 2 are all slidably installed on the base plate 1. The ends of the frames 2 away from the base plate 1 are provided with multiple top grooves 13. Fixing seats 5 are installed inside the frames 2. The fixing seats 5 are all set away from the top grooves 13. Each fixing seat 5 is provided with a bottom groove 6. Reagent tubes 12 are provided in the vertically opposite top grooves 13 and bottom grooves 6. Limiting shells 9 are installed on the outside of the frames 2 located in the top grooves 13. The inner ring of the limiting shells 9 is recessed to form a limiting groove 14. The outer ring of the tube cap 10 on the reagent tube 12 is inserted into the limiting groove 14. The outer end face of the tube cap 10 is in contact with the inner wall surface of the limiting shell 9. Each frame 2 can be detachably installed with a pressure plate 8 to press and position the multiple reagent tubes 12.

[0020] In this embodiment, the virus purification kit has connecting seats 7 installed at both ends inside the frame 2. The connecting seats 7 are provided with positioning grooves on the end face of the pressure plate 8. One end of the positioning groove is enlarged to form an inlet / outlet groove 16 that communicates with the outside. Positioning blocks 15 are installed on the inner side of the pressure plate 8 opposite to the positioning grooves. The positioning blocks 15 are inserted into the positioning grooves.

[0021] In this embodiment, each pressure plate 8 has a positioning block 15 of different lengths. The inner wall of the groove 16 on one side is provided with a groove, and a positioning plate 11 is provided in each groove. One end of the positioning plate 11 extends to the outside and abuts against the end face of the corresponding positioning block 15. The other end of the positioning plate 11 is inserted into the groove and is equipped with a compression spring. The other end of the compression spring is installed on the inner wall of the groove.

[0022] In this embodiment, the end of the positioning block 15 away from the inlet / outlet groove 16 is set to abut against the positioning groove. The cross-sections of both the positioning block 15 and the positioning groove are set in a trapezoidal structure, so that after the positioning block enters the positioning groove, it is prevented from moving directly outward.

[0023] In this embodiment, the base plate 1 is provided with multiple connecting grooves 3, and a placement rack 4 is installed on one side of the frame 2. The placement rack 4 is slidably disposed in the connecting groove 3. The connecting groove 3 is arranged in a trapezoidal structure, while the placement rack 4 is arranged in a figure-eight structure. The figure-eight structure of the placement rack allows the frame to be placed independently on the table.

[0024] In this embodiment, the vertical cross-section of the frame 2 is set in a "U" shape, which makes the middle of the frame hollow, so that the reagent tube can be smoothly inserted into the interior of the frame.

[0025] In this embodiment, the inner diameters of the top groove 13 and the bottom groove 6 are matched with the diameter of the reagent tube 12, which increases the stability after insertion.

[0026] The racks are all slidably mounted on the base plate via a placement rack, so that each rack is a group, which can distinguish the reagent tubes. After the racks are removed along the connecting groove, they can be placed independently by the placement rack, which greatly reduces the probability of confusion.

[0027] During installation, the top of the reagent tube can be inserted into the top groove and the bottom into the bottom groove, while the tube cap can enter the limiting groove and be squeezed by the inner wall of the limiting block, thereby pressing the reagent tube tightly from top to bottom and also pressing the tube cap to prevent it from opening and causing the internal virus to be exposed.

[0028] After the above is completed, align the positioning block on the pressure plate with the inlet / outlet slot and enter the inlet / outlet slot. After pushing the pressure plate horizontally, the positioning block can enter the positioning slot. The pressure plate can hold down multiple reagent tubes, preventing swaying and tipping, and increasing stability. As the pressure plate is pushed into place, the rebound of the compression spring can push the positioning plate outward, and the positioning plate can abut against the end face of the positioning block, thereby positioning the pressure plate and increasing stability.

[0029] Conversely, during disassembly, the positioning plate can be squeezed inward. After the positioning plate retracts into the groove, the positioning block moves outward into the inlet / outlet slot. At this time, the pressure plate can be directly removed outward. After the pressure plate is no longer obstructed, the reagent tube can be directly removed outward, which facilitates disassembly. Moreover, when the pressure plate is no longer obstructed, the tube cap is restricted by the limiting shell, preventing the reagent tube from tilting outward on its own.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
