Abstract
Description
Technical Field
[0001] This utility model relates to the field of reagent ice box technology, and in particular to a PCR reagent ice box with good heat preservation effect. Background Technology
[0002] In the field of molecular biology experiments, PCR technology plays a crucial role, and the proper storage of PCR reagents is of paramount importance to the accuracy of experimental results. As a key device for ensuring a low-temperature environment for the reagents, the performance of PCR reagent coolers directly affects the success or failure of the experiment.
[0003] Most PCR reagent ice boxes consist of a box body and a lid. Ice packs are placed inside the box, and a test tube rack is installed inside the box. When the lid is closed, a sealed space is formed between the lid and the box body, which effectively prevents cold air leakage and improves the insulation effect. However, when staff open the lid to take out or put in test tubes, a large amount of cold air will leak out. The box body is also prone to heat exchange with the external environment, causing the ice packs to melt quickly and affecting the subsequent refrigeration and insulation effect. Utility Model Content
[0004] The purpose of this invention is to provide a PCR reagent ice box with good heat preservation effect in order to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A PCR reagent ice box with good heat preservation includes a box body and a lid hinged to one side of the upper end of the box body. The outer surface of the lid is provided with a latch that cooperates with the box body. A test tube rack is slidably arranged inside the box body. An insulated box is provided on the bottom surface of the inner box body. Multiple openings for test tubes to pass through are evenly distributed on the surface of the test tube rack. Corner brackets are fixed at the four corners of the upper end of the test tube rack. The corner brackets are fixedly connected to the inner wall of the box body by bolts. Sealing components that cooperate with the openings are provided at the upper end of the test tube rack.
[0007] As a further description of the above technical solution:
[0008] The sealing assembly includes a sealing cap for covering the upper end of the opening and an L-shaped connecting block fixed on the outer surface of the sealing cap. One end of the L-shaped connecting block is hinged to the upper end of the test tube rack. A sealing ring is tightly slidably fitted on the outer side of the sealing cap. The side wall of the sealing ring has a sliding groove that mates with the L-shaped connecting block. The upper end of the test tube rack has an annular groove for the sealing ring to slide into.
[0009] As a further description of the above technical solution:
[0010] The upper end of the sealing cover is provided with a rotating disk, which is rotatably connected to the upper end of the sealing cover via a rotating shaft. The upper surface of the sealing cover has two color gamuts, and the surface of the rotating disk has a viewing port for penetrating the color gamuts.
[0011] As a further description of the above technical solution:
[0012] It also includes a pull rope for pulling the sealing ring upwards, with both ends of the pull rope fixedly connected to the upper end of the sealing ring.
[0013] As a further description of the above technical solution:
[0014] The box body has thermal insulation layers on its side walls and bottom.
[0015] As a further description of the above technical solution:
[0016] The outer surface of the test tube rack is provided with a sealing layer that fits tightly with the inner wall of the box.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0018] In this invention, by setting up a test tube rack, a slit, a sealing cap, an L-shaped connecting block, a sealing ring, and an annular groove, the sealing cap can cover the slit. When a test tube is placed on the slit, the sealing cap can cover the top of the test tube. When no test tube is placed on the slit, the sealing cap can cover the slit. This keeps the upper and lower layers of the test tube rack in a sealed state, creating a long-lasting, low-temperature, stable, and reliable storage condition for reagents, and preventing a large amount of cold air from leaking out when the lid is opened.
[0019] In this invention, the sealing ring and the annular groove work together to ensure the sealing performance at the connection between the sealing cap and the test tube rack, and to limit the opening of the sealing cap, thus ensuring the stability of the sealed cap in the closed state.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1-5 As shown, a PCR reagent ice box with good insulation includes a box body 1 and a lid 2 hinged to one side of the upper end of the box body 1. The outer surface of the lid 2 has a latch 3 that cooperates with the box body 1. A test tube rack 4 is slidably arranged inside the box body 1. An insulation box 5 is arranged on the inner bottom surface of the box body 1. Multiple openings 6 for test tubes to pass through are evenly distributed on the surface of the test tube rack 4. Angle brackets 7 are fixed at the four corners of the upper end of the test tube rack 4. The angle brackets 7 are fixedly connected to the inner wall of the box body 1 by bolts. The upper end of the test tube rack 4 is provided with sealing components that cooperate with the openings 6. In use, the staff places the prepared ice pack in the insulation box 5, and then installs the test tube rack 4 inside the box body 1, so that the test tube rack 4 is tightly pressed against the upper end of the insulation box 5. Under the action of the sealing components, a sealed space is formed inside the insulation box 5, which improves the insulation effect. When it is necessary to place test tubes, the staff opens the sealing components, then passes the test tubes through the openings 6, and finally closes the sealing components.
[0028] Furthermore, the sealing assembly includes a sealing cap 10 for covering the upper end of the opening 6 and an L-shaped connecting block 15 fixedly disposed on the outer surface of the sealing cap 10. One end of the L-shaped connecting block 15 is hinged to the upper end of the test tube rack 4. A sealing ring 9 is tightly slidably fitted on the outer side of the sealing cap 10. The side wall of the sealing ring 9 has a groove 14 that mates with the L-shaped connecting block 15. The upper end of the test tube rack 4 has an annular groove 8 for the sealing ring 9 to slide into. In use, the operator drives the sealing ring 9 upward, causing the sealing ring 9 to disengage from the annular groove 8. Then, the sealing cap 10 can be flipped open to expose the opening 6, allowing the test tube to be inserted through the opening 6 for installation. After installation, the operator flips the sealing cap 10 back to close it, covering the test tube with the sealing cap 10. Then, the sealing ring 9 is driven to slide downwards, allowing it to slide into the annular groove 8. Under the action of the sealing ring 9, the sealing cap 10 and the test tube rack 4 are sealed, and the opening of the sealing cap 10 is limited, ensuring the stability of the closed state of the sealing cap 10.
[0029] Furthermore, a rotating disk 11 is provided at the upper end of the sealing cover 10. The rotating disk 11 is rotatably connected to the upper end of the sealing cover 10 via a rotating shaft. The upper surface of the sealing cover 10 has two color gamuts. A viewing port 12 for penetrating the color gamut is opened on the surface of the rotating disk 11. The operator rotates the rotating disk 11 to make the viewing port 12 appear in different color gamuts, which is convenient for the operator to check whether the lower end of the sealing cover 10 is covered with a test tube. In use, after the sealing cover 10 is opened, the test tube is placed in the opening 6. After the operator closes the sealing cover 10, the rotating disk 11 is rotated to adjust the viewing port 12 to one of the color gamuts. After the sealing cover 10 is opened and the test tube in the opening 6 is removed, the operator closes the sealing cover 10 and then rotates the rotating disk 11 to adjust the viewing port 12 to the other color gamut.
[0030] Furthermore, it also includes a pull rope 13 for lifting the sealing ring 9 upwards. The two ends of the pull rope 13 are fixedly connected to the upper end of the sealing ring 9. In use, the operator can lift the pull rope 13 upwards to make the sealing ring 9 slide upwards.
[0031] Furthermore, the side walls and bottom of the box body 1 are provided with heat insulation layers, which improves the heat insulation effect of the box body 1.
[0032] Furthermore, the outer surface of the test tube rack 4 is provided with a sealing layer that fits tightly with the inner wall of the box body 1, ensuring the sealing effect between the test tube rack 4 and the box body 1, thereby ensuring the heat preservation effect of the box body 1.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
