Description

Technical Field

[0001] The utility model relates to the technical field of optical detection, in particular to an inlet and outlet bin assembly suitable for detecting large and small reagent discs. Background Art

[0002] Existing reagent testing equipment is typically only suitable for a single reagent tray size, such as a large or small one, lacking compatibility. This limitation in equipment design means that when handling different types of experiments, especially when testing multiple reagent trays, users must configure multiple equipment sizes to meet their needs. For example, when a laboratory needs to test both large and small reagent trays, since existing equipment is only designed to accommodate a certain size, it is necessary to purchase different testing equipment corresponding to the large and small reagent trays.

[0003] This single-function design brings several significant disadvantages: First, the equipment costs are high. The need to purchase two or even multiple specifications of equipment significantly increases the laboratory's equipment purchase costs, placing financial pressure on small laboratories or users with limited resources. Second, the increase in the number of devices leads to increased laboratory space requirements, which is particularly inconvenient when operating space is limited. In addition, the maintenance of multiple devices also increases operation and maintenance costs, requiring users to spend more time on equipment maintenance and management.

[0004] From an operational efficiency perspective, the limitations of existing equipment also hinder flexibility during testing. For example, when different reagent disc sizes are required within the same experiment, operators must frequently switch between devices during testing, resulting in unnecessary time waste and reduced overall testing efficiency. Therefore, achieving compatibility with different reagent disc sizes on a single device has become a key issue in resolving current technical challenges. Utility Model Content

[0046] Example 1

[0047] See also Figures 1 to 10 , which is an in-and-out bin assembly 1400 suitable for detecting large and small reagent trays 1502, proposed in an embodiment of the present invention. The in-and-out bin assembly 1400 is used to connect to the main body of an external test device. The in-and-out bin assembly 1400 includes a limiting structure 1401, an in-and-out bin support frame 1402, a position sensor 1403 and a driving assembly 1404. The in-and-out bin support frame 1402 includes a fixing frame 1405, a limiting rod 1406 and a stepping gear rod 1407. The limiting rod 1406 and the stepping gear rod 1407 are arranged in parallel and are respectively connected to both sides of the fixing frame 1405. The driving assembly 1404 is connected to the support frame; the limiting structure 1401 is connected to the device The device is connected to the main body, the limit rod 1406 is slidably connected to the limit structure 1401, the limit structure 1401 is used to limit the extension and retraction direction of the limit rod 1406, and the stepping gear rod 1407 is used to engage with the external stepping motor 1408 to drive the in-and-out warehouse support frame 1402 to extend and retract under the action of the stepping motor 1408; the position sensor 1403 is connected to the device body and is used to detect the extension and retraction stroke of the limit rod 1406, the driving component 1404 is used to connect to the external magnetic mounting component 1500, the magnetic mounting component 1500 includes a magnetic mounting seat 1501, and the magnetic mounting seat 1501 is used to install an external reagent disk 1502.

[0048] Specifically, the in-and-out bin assembly 1400 is used to improve the compatibility and efficiency of the reagent disc 1502 detection equipment. The in-and-out bin assembly 1400 can be applied to reagent discs 1502 of different specifications, so that a single device can handle the detection needs of various reagent discs 1502 in the laboratory, reducing equipment costs and space occupancy. This specific embodiment includes the following main parts: the in-and-out bin assembly 1400 mainly includes a limiting structure 1401, an in-and-out bin support frame 1402, a position sensor 1403 and a drive assembly 1404; the in-and-out bin support frame 1402 includes a fixed frame 1405, a limiting rod 1406 and a stepping gear rod 1407. The limiting rod 1406 and the stepping gear rod 1407 are arranged in parallel and are respectively connected to both sides of the fixed frame 1405. The fixed frame 1405 provides overall support, while the limiting rod 1406 and the stepping gear rod 1407 are used to adjust the extension and retraction of the support frame to accommodate the installation and testing of reagent trays 1502 of different sizes. The drive assembly 1404 is mounted on the support frame and is used to connect to the external magnetic mounting assembly 1500. The drive assembly 1404 drives the stepping gear rod 1407 through an external stepping motor 1408, which meshes with the gears to control the extension and retraction of the in-and-out support frame 1402.

[0049] The limiting structure 1401 is used to connect to the main body of the device. The limiting rod 1406 is connected to the limiting structure 1401 through a sliding connection, and is constrained by the limiting structure 1401 so that it can only perform telescopic movement in a specific direction. This design ensures the movement stability and controllability of the support frame, preventing accidental displacement during operation, which affects the detection of the reagent tray 1502. The stepping gear rod 1407 in the inlet and outlet assembly 1400 is engaged with the external stepping motor 1408. The stepping motor 1408 drives the stepping gear rod 1407 to perform linear motion by rotation, thereby pushing the inlet and outlet support frame 1402 to extend and retract. This design is not only accurate, but also has good control performance. It can accurately adjust the position of the inlet and outlet according to the detection requirements to accommodate reagent trays 1502 of different specifications. The position sensor 1403 is used to detect the telescopic stroke of the limiting rod 1406 to ensure that it can be detected in time every time the inlet and outlet support frame 1402 is extended and retracted into place. This helps the testing device calibrate the position of the reagent tray 1502, preventing inaccurate test results caused by inaccurate installation of the reagent tray 1502. Drive assembly 1404 is connected to an external magnetic mounting assembly 1500, which includes a magnetic mounting base 1501 for mounting the external reagent tray 1502. Magnetic mounting base 1501 makes installation and removal of the reagent tray 1502 quick and easy, reducing the complexity of manual operation and improving the overall efficiency of the testing device.

[0050] Through the above-described structural design, the practical access chamber assembly 1400 can flexibly adapt to reagent trays 1502 of varying specifications, enabling multi-purpose use of the same device, significantly reducing equipment acquisition and maintenance costs, and optimizing laboratory resource allocation. The coordination of the limiting structure 1401, position sensor 1403, and drive assembly 1404 allows for precise and controllable expansion and contraction of the support frame, thereby improving detection efficiency while ensuring safety and accuracy during the detection process.

[0051] Example 2

[0052] In this embodiment, the structure of the in-and-out bin assembly 1400 suitable for detecting large and small reagent discs 1502 is further optimized on the basis of Example 1 to improve the accuracy and stability of the detection, and a detailed structural description of the position sensor 1403 and the magnetic mounting assembly 1500 is added.

[0053] In this embodiment, position sensor 1403 is preferably an infrared sensor 1409. Limiting rod 1406 is provided with multiple detection ports 1410. Infrared sensors 1409 are connected to the device body, and the positions of detection ports 1410 are used to determine the travel distance of the in-and-out support frame 1402. This design improves the accuracy of the detection process and ensures that the movement state of the support frame can be controlled in real time, thereby better accommodating reagent trays 1502 of different specifications.

[0054] The magnetic mounting assembly 1500 includes a magnetic mounting base 1501 and a reagent tray 1502. The reagent tray 1502 comprises a tray body 1503 and a mounting base 1504 connected to the tray body 1503. A tray cover 1505 covers the top of the tray body 1503. The tray body 1503 is provided with a liquid inlet 1506. The mounting base 1504 is provided with a receiving chamber 1507, which is connected to the liquid inlet 1506. The inner wall of the liquid inlet 1506 is provided with a puncture structure 1508. The receiving chamber 1507 is provided with a dilution box 1509 and a magnetic sheet 1510. The magnetic sheet 1510 engages with the inner wall of the receiving chamber 1507 and confines the dilution box 1509 between the magnetic sheet 1510 and the puncture structure 1508. A sealing film 1511 is provided on the top of the dilution box 1509. The sealing film 1511 is located at the bottom end of the puncture structure 1508. The magnetic sheet 1510 is provided with a perforation 1512. The disk cover 1505 may be a layer of film.

[0055] Magnetic mounting base 1501 includes a mounting body 1513 and a limiting mechanism 1514 disposed on mounting body 1513. Limiting mechanism 1514 comprises a positioning structure 1515 and a guide structure 1516, each of which is connected to the top of mounting body 1513. Positioning structure 1515 is disposed on the periphery of guide structure 1516, forming an annular mounting cavity 1517 between positioning structures 1515. A mounting cavity 1518 for magnet 1520 is disposed within guide structure 1516. Magnet 1520 is disposed within the mounting cavity, and a protruding structure 1521 is disposed on top of magnet 1520.

[0056] When mounting base 1504 is connected to magnetic mounting base 1501, magnetic sheet 1510 is attracted by magnet 1520. Raised structure 1521 on top of magnetic mounting base 1501 passes through perforation 1512 on magnetic sheet 1510, pushing dilution cartridge 1509 upward. Piercing structure 1508 then pierces sealing film 1511, allowing the diluent in dilution cartridge 1509 to enter disk 1503 through piercing structure 1508. This structural design automatically pierces sealing film 1511 of dilution cartridge 1509 and introduces the diluent into disk 1503, simplifying pre-test preparations and improving testing convenience and efficiency.

[0057] The outer periphery of the mounting body 1513 is provided with an adjustment tooth ring 1522 for fine-tuning the mounting position to ensure the accurate installation of the reagent tray 1502. The magnetic mounting assembly 1500 also includes a fixing bolt, a mounting hole 1523 is provided at the bottom of the mounting body 1513, a connecting hole 1524 is provided on the magnet 1520 that is adapted to the mounting hole 1523, and a threaded hole 1525 is provided on the raised structure 1521. One end of the threaded rod of the fixing bolt passes through the mounting hole 1523, the connecting hole 1524 and the threaded hole 1525 in sequence to fix the mounting body 1513, the magnet 1520 and the raised structure 1521. This design ensures the stability of the entire assembly during use and avoids loosening due to vibration or external force. The mounting body 1513 is provided with one or more external holes 1526 for connecting other auxiliary devices to increase the scalability and compatibility of the equipment. The inner wall of the positioning structure 1515 is surrounded by multiple groups of straight-face structures 1527, which are connected end to end and projected into an equilateral polygon. The top of the straight-face structure 1527 is provided with a guide surface 1528, and the connection of the straight-face structure 1527 is provided with an air pressure balance groove 1529 to balance the internal air pressure during the installation process and avoid operational difficulties caused by air pressure changes. The height of the guide structure 1516 is preferably greater than the height of the positioning structure 1515, and the top peripheral edge of the guide structure 1516 is provided with an arc-shaped guide surface 1530. This design helps to guide the positioning during the installation process and reduce errors. The positioning structure 1515 is provided with one or more groups of positioning holes 1531, which are connected to the annular installation cavity 1517. The positioning holes 1531 are used to help the reagent disk 1502 to be accurately positioned during the installation process to ensure the accuracy of the detection.

[0058] Through the above optimization, this embodiment further improves the compatibility and stability of the inlet and outlet assembly 1400 during the detection process of reagent trays 1502 of different specifications, not only making the device more convenient to operate, but also effectively ensuring the accuracy and consistency of detection. During the detection process, the coordinated operation of the limit structure 1401, infrared position sensor 1403, magnetic mounting assembly 1500, and multiple preferred components jointly achieves efficient and accurate detection of reagent trays 1502 of different specifications.

[0059] Example 3

[0060] In this embodiment, based on the basic design of Examples 1 and 2, the inlet and outlet chamber assembly 1400 is further optimized, especially the puncture structure 1508, the snap-fit ​​structure of the accommodating chamber 1507, and the anti-rotation and fixing functions of the magnetic mounting base 1501 are improved to further improve the stability and reliability of the assembly during the detection process of the reagent disk 1502. The puncture structure 1508 includes a puncture blade 1532 and abutment walls 1533 arranged on both sides of the puncture blade 1532. The main function of the puncture blade 1532 is to puncture the sealing membrane 1511 of the dilution box 1509 to allow the diluent to enter the interior of the disk body 1503, while the abutment walls 1533 play a stabilizing and supporting role during the puncture process, preventing the puncture blade 1532 from deflecting during the puncture process.

[0061] The puncturing blade 1532 and two sets of abutment walls 1533 are both connected to the inner wall of the liquid inlet 1506. The puncturing blade 1532 is sharp and strong, easily piercing the sealing membrane 1511, while the abutment walls 1533 provide lateral support on both sides of the puncturing blade 1532. The two sets of abutment walls 1533 enclose a diluent channel 1534, which communicates with a flow channel 1535 within the disc body 1503, ensuring that the diluent can flow smoothly from the dilution cartridge 1509 into the disc body 1503, reducing the risk of liquid leakage and detection uncertainty.

[0062] Liquid inlet 1506 is surrounded by an enclosure wall, the top surface of which is flush with the top of abutment wall 1533, providing balanced support and stability. A liquid inlet channel 1537 is also provided on the enclosure wall, communicating with diluent channel 1534. This design facilitates rapid and smooth entry of liquid into disc body 1503 after puncturing sealing membrane 1511, preventing liquid spillage and interruption of testing.

[0063] Inside the accommodating cavity 1507, there are multiple sets of locking platforms 1538, and the top of the locking platforms 1538 is provided with opening and closing grooves 1539, and the periphery of the magnetic sheet 1510 is provided with cards and protrusions 1540 matching the locking platforms 1538, and these cards and protrusions 1540 are adapted to the opening and closing grooves 1539.

[0064] A mounting channel is formed between the multiple sets of engaging platforms 1538, which is used to guide the magnetic sheet 1510 and the protrusion 1540 to rotate and engage in the opening and closing slot 1539 after passing through the mounting channel. This design ensures the stability of the magnetic sheet 1510 in the accommodating cavity 1507, and prevents the magnetic sheet 1510 from being dislocated due to external factors such as vibration during operation. The magnetic sheet 1510 is provided with one or more sets of limiting holes 1541 around the periphery of the through hole 1512. When subjected to external force, the limiting holes 1541 can rotate and engage in the opening and closing slot 1539. This limiting design improves the firmness of the engagement between the magnetic sheet 1510 and the accommodating cavity 1507 by adding additional fixing points, ensuring that the magnetic sheet 1510 does not move during the detection process, and further improving the overall reliability of the device.

[0065] The inner walls of multiple sets of engaging platforms 1538 enclose an inner engaging wall mechanism 1542. This inner engaging wall mechanism 1542 is used to position the mounting base 1504 when connected to the magnetic mounting base 1501. This positioning design ensures precise alignment during installation, reduces installation errors, and improves overall inspection accuracy. A curved guide structure 1543 is designed at the bottom of the engaging platform 1538. This curved design guides the installation process, making the engagement process smoother and effectively reducing component wear or failure caused by inaccurate engagement.

[0066] In order to ensure the stability when the mounting base 1504 is combined with the magnetic mounting base 1501, the bottom periphery of the mounting base 1504 is provided with an anti-rotation structure 1544, which can effectively prevent the mounting base 1504 from rotating due to external force during the detection process. Preventing rotation is crucial for ensuring the positioning of the reagent disk 1502, because even a slight rotation may cause inaccurate test results. A plurality of fixing holes 1545 are also provided on the mounting base 1504, which are connected to the magnetic mounting base 1501 during installation. Through these fixing holes 1545, the mounting base 1504 and the magnetic mounting base 1501 can be firmly combined together using fixing bolts to ensure the stability of the entire assembly during the detection process and prevent loosening due to vibration or improper operation.

[0067] Magnetic sheet 1510 is preferably made of iron. This material ensures good adhesion between magnetic sheet 1510 and magnetic mounting base 1501, allowing it to be stably engaged with protrusion 1521 of magnetic mounting base 1501 under the action of magnet 1520. During the testing process, magnetic sheet 1510 effectively secures dilution cartridge 1509 in a predetermined position, preventing displacement of dilution cartridge 1509 due to liquid movement or external forces.

[0068] One or more sets of positioning holes 1531 are defined on the inner wall of positioning structure 1515. These holes 1531 communicate with annular mounting cavity 1517, ensuring precise alignment of reagent tray 1502 during installation. A pressure balancing groove 1529 is defined at the junction of facing structure 1527. This groove balances pressure fluctuations between the interior and exterior of chamber 1507 during installation, preventing assembly difficulties caused by pressure differences and ensuring successful installation of reagent tray 1502 under all conditions.

[0069] In the present embodiment, the height of the guide structure 1516 is preferably greater than the height of the positioning structure 1515, and the top peripheral edge thereof is provided with an arc-shaped guide surface 1530. Such a design helps to smoothly guide the reagent tray 1502 into the correct position during the installation process, reduce errors and jamming, and improve the efficiency and success rate of installation before detection. Through the further improvement of the present embodiment, the adaptability of the entire inlet and outlet assembly 1400 in the detection of reagent trays 1502 of different specifications has been significantly improved. The puncture structure 1508, the limiting design of the magnetic sheet 1510, the locking mechanism of the accommodating cavity 1507, and the optimization of the anti-rotation and fixing structure make the entire detection process not only more stable and reliable, but also more simple and efficient, which contributes to the flexible application of reagent trays 1502 of different specifications in the laboratory and the efficient operation during the detection process.

[0070] Preferably, a sealing plate 1411 is further included, which is connected to the inlet and outlet support frame 1402 and is arranged on a side away from the stepping gear rod 1407. A dustproof plate 1412 is also included, which is arranged at the upper end of the drive assembly 1404 and the lower end of the external reagent disk 1502 and is connected to the sealing plate 1411.

[0071] In short, the above are only preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of the present invention.
