Description

Technical Field

[0001] This utility model relates to the field of pesticide residue detection equipment technology, and in particular to a pesticide residue detection kit based on imprinted gel. Background Technology

[0002] Imprinted gels are a novel type of polymer capable of specifically recognizing template molecules. However, to integrate the reagents required for detection, standardize the process, ensure specificity and accuracy, and simplify operation, pesticide residue detection kits based on imprinted gel technology have emerged. These kits contain multiple test tubes as reaction containers to hold the sample, reagents, and imprinted gel particles (or membranes) for the extraction, separation, and detection of pesticide residues. Currently, some kits, to fit packaging specifications and reduce costs, often arrange the test tubes compactly to compress space. While this design saves volume, it restricts finger operation, making it prone to slipping and accidental contact when wearing gloves, and the tightly fitted grooves further reduce the operating space. Simultaneously, excessively narrow spacing between test tubes reduces stability; external forces are easily transmitted during handling or touching, and vibrations during operation can easily cause multiple test tubes to tip over, or even lead to reagent leakage. Utility Model Content

[0003] The purpose of this invention is to address the problems of current reagent kits, which, due to the compact arrangement of reagent tubes to reduce costs, restrict finger operation, are prone to accidental contact when wearing gloves, have poor stability due to narrow spacing, and are easily tipped over and leaked by vibration during operation. This invention proposes a pesticide residue detection kit based on an imprint gel.

[0004] The technical solution of this utility model is as follows: a pesticide residue detection kit based on imprinted gel, comprising a box body and multiple pairs of first and second test tubes inserted into the box body, and further comprising: multiple placement cavities arranged linearly in the box body and corresponding to the first and second test tubes; multiple pairs of first and second pressing rods corresponding to the first and second test tubes disposed on the box body; and a lever mechanism installed in the placement cavities to cause the corresponding first and second test tubes to protrude from the placement cavities.

[0005] Optionally, the lever mechanism includes a support frame fixedly connected to the placement cavity. A pair of long rotating rods and short rotating rods are rotatably connected inside the support frame. One end of the long rotating rod is connected to the second pressing rod, and one end of the short rotating rod is connected to the first pressing rod. The other ends of the long rotating rod and the short rotating rod are both fixedly connected to arc-shaped pry pads that support the corresponding first and second test tubes.

[0006] Optionally, the arc-shaped pry pad is made of rubber.

[0007] Optionally, the support frame is internally fixedly connected to a pair of support plates corresponding to the long rotating rod and the short rotating rod. Each support plate has a return spring fixedly connected to its upper surface, and the end of the return spring away from the support plate is fixedly connected to the corresponding long rotating rod and the short rotating rod.

[0008] Optionally, the top of the box is provided with a rotating cover plate that blocks the first test tube, the second test tube, the first pressing rod, and the second pressing rod.

[0009] Optionally, the box body is provided with a suction groove, the suction groove is provided with a magnetic piece, and the rotating cover is provided with a metal piece that is inserted into the suction groove and attracted to the magnetic piece.

[0010] Optionally, one end of both the first and second pressing rods is provided with a spherical pressing head.

[0011] Optionally, the box body is provided with a placement slot for placing the testing tool.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a combination of a placement cavity, a first pressing rod, a second pressing rod, and a lever mechanism. By pressing the first and second pressing rods with a single finger, the lever mechanism causes the corresponding first and second test tubes to pop out of the placement cavity. This eliminates the need for fingers to reach into narrow spaces, solving the problem of inconvenience caused by compact arrangement and preventing reagent leakage due to contact with other test tubes during use. After use, the test tubes are placed back into the box and precisely locked in place by the reset structure inside the placement cavity. Combined with the magnetic closure of the rotating cap, this reduces the risk of shaking and tipping during transportation. Attached Figure Description

[0024] Example

[0025] like Figures 1 to 3 As shown, this utility model proposes a pesticide residue detection kit based on imprinted gel, comprising a box body 1 and multiple pairs of first test tubes 102 and second test tubes 103 inserted inside the box body 1. The box body 1 has a placement slot 106 for placing detection tools. The placement slot 106 provides dedicated storage space for tools used in the detection process, such as droppers and pipettes, preventing tools from being randomly placed inside the box. This facilitates quick location and retrieval of necessary tools by testing personnel when using the kit for pesticide residue detection, improving detection efficiency. The top of the box body 1 has a rotating cover 2 that blocks the first test tube 102, second test tube 103, first pressing rod 104, and second pressing rod 105. The rotating cover 2 is used to block the test tubes and pressing rods, preventing them from shifting during transportation. The box body 1 has multiple placement cavities 101 arranged in a linear pattern and corresponding to the first test tube 102 and the second test tube 103. The box body 1 has multiple pairs of first pressing rods 104 and second pressing rods 105 corresponding to the first test tube 102 and the second test tube 103. One end of the first pressing rod 104 and the second pressing rod 105 is provided with a spherical pressing head. The structure of the spherical pressing head makes the force even when the finger presses, reduces the pressing resistance, and improves the operating comfort.

[0026] Among them, such as Figure 2 , Figure 3 As shown, a lever mechanism is installed in the placement cavity 101 to allow the corresponding first test tube 102 and second test tube 103 to protrude from the placement cavity 101. The lever mechanism includes a support frame 11 fixedly connected in the placement cavity 101. A pair of long rotating rods 12 and short rotating rods 13 are rotatably connected inside the support frame 11. One end of the long rotating rod 12 is connected to the second pressing rod 105, and one end of the short rotating rod 13 is connected to the first pressing rod 104. The other ends of the long rotating rod 12 and the short rotating rod 13 are fixedly connected to arc-shaped pry pads 14 that support the corresponding first test tube 102 and second test tube 103. The arc-shaped pry pads 14 are made of rubber. The purpose of using rubber in the arc-shaped pry pads 14 is to ensure that the first test tube 102 and the second test tube 103 will not be crushed due to the hardness of the material after the long rotating rod 12 and the short rotating rod 13 rotate.

[0027] In addition, such as Figure 3 As shown, a pair of support plates 15 corresponding to the long rotating rod 12 and the short rotating rod 13 are fixedly connected inside the support frame 11. A return spring 16 is fixedly connected to the upper surface of each support plate 15. The return spring 16 returns the long rotating rod 12 and the short rotating rod 13 to their original positions, ensuring that the long rotating rod 12 and the short rotating rod 13 can work repeatedly. The end of the return spring 16 away from the support plate 15 is fixedly connected to the corresponding long rotating rod 12 and the short rotating rod 13.

[0028] It is worth noting that, such as Figure 1 and Figure 2As shown, the box body 1 has a suction groove 107. A magnetic piece is installed inside the suction groove 107. The magnetic piece is made of a circular material used to attract iron. It is positioned on the rotating cover plate 2, causing a circular protrusion on the rotating cover plate 2 that engages perfectly with the suction groove 107. The rotating cover plate 2 has a metal piece made of iron that engages with the magnetic piece within the suction groove 107.

[0029] In this embodiment, when using the pesticide residue detection kit with the imprinted gel, the first pressing rod 104 and the second pressing rod 105 are pressed first. The first pressing rod 104 presses against the short rotating rod 13, causing it to rotate within the support frame 11. Then, the end of the short rotating rod 13 away from the first pressing rod 104 lifts upwards, pushing the second test tube 103 out of the placement cavity 101, making it easier to retrieve. Next, the second pressing rod 105 presses against the long rotating rod 12, causing it to rotate within the support frame 11 as well. The end of the long rotating rod 12 away from the second pressing rod 105 eventually pries the first test tube 102 out of the placement cavity 101, also facilitating its retrieval. When the first pressing rod 104 and the second pressing rod 105 are released, both the long rotating rod 12 and the short rotating rod 13 return to their original positions due to the elastic force of the return spring 16 on the support plate 15, making the process convenient and quick. Finally, the rotating cover 2 is placed on top of the box 1, and the metal sheet inside the rotating cover 2 and the magnetic sheet inside the suction groove 107 attract each other to achieve a magnetically closed state.

[0030] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
