DETAILED DESCRIPTION

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1-5 As shown, this embodiment provides a contamination-proof cartridge structure for a reagent kit, including a storage box body 1. A sealing pad 5 is disposed inside the storage box body 1. The sealing pad 5 has an array of docking perforations 504 inside, and a sealing valve 505 is installed inside each docking perforation 504. A reagent tube holder 103 is arranged in an array directly below the docking perforation 504 inside the storage box body 1. The center of the docking perforation 504 corresponds to the center of the reagent tube holder 103. The inner diameter of the docking perforation 504 is greater than the outer diameter of the reagent tube holder 103. Limiting sliders 50 are installed on both sides of the sealing pad 5. 2. A limiting groove 101 is formed on the outer side of the limiting slider 502 on the inner side wall of the storage box 1. The sealing pad 5 is slidably connected to the limiting groove 101 through the limiting slider 502. A movable through hole 102 is formed on the upper surface of the limiting groove 101. A pressing rod 501 is installed inside the movable through hole 102 on the upper surface of the limiting slider 502. The inner diameter of the movable through hole 102 is longer than the outer diameter of the pressing rod 501. A spring 503 is connected between the lower surface of the limiting slider 502 and the limiting groove 101. The limiting slider 502 is fixedly connected to the limiting groove 101 through the spring 503.

[0018] like Figures 2-3 As shown, in this embodiment, an upper sealing cover 2 is provided on the top of the storage box 1. Buckles 4 are provided on both sides of the upper sealing cover 2. An elastic pivot is installed between the buckles 4 and the upper sealing cover 2. A slot 6 is provided on the outer surface of the storage box 1 corresponding to the buckle 4. A folding handle 3 is installed on the upper surface of the upper sealing cover 2. A storage groove is provided on the upper surface of the storage box 1 outside the folding handle 3. A movable shaft is installed between the folding handle 3 and the upper sealing cover 2. The buckles 4 and the slot 6 are engaged.

[0019] The working principle of this invention is as follows: During storage and use, the reagent is inserted from the sealing valve 505 inside the connecting perforation 504 on the sealing pad 5 into the reagent tube 103 inside the storage box 1. Then, the upper sealing cover 2 is placed over the storage box 1 from above. Pressing the upper sealing cover 2 downwards on the storage box 1 causes the upper sealing cover 2 to press down on the pressing rod 501. This causes the sealing pad 5 to deform by pressing down on the inner wall of the limiting groove 101 via the limiting slider 502. Once the upper sealing cover 2 is fully in place, the buckle 4 on the outside of the upper sealing cover 2 engages with the slot 6, completing the connection between the upper sealing cover 2 and the storage box 1. After the limit is reached, the folding handle 3 on the upper surface of the upper sealing cover 2 can be rotated and unfolded for carrying. When it is necessary to take out the reagent from the inside of the storage box 1, the upper sealing cover 2 is disassembled by pushing the buckle 4 outward. Then, the sealing pad 5 moves upward under the reset force of the spring 503 and covers the outside of the reagent tube. Therefore, when it is necessary to take out the reagent, the pressing rod 501 is pressed down again to push the reagent tube out from the inside of the sealing valve 505. After taking out the reagent tube in the corresponding position, the force of the pressing rod 501 is released, and the sealing pad 5 will cover the outside of the reagent tube again, preventing the reagent tube inside from being contaminated due to forgetting to close the upper sealing cover 2 for a long time.
