[0015] As a preferred technical solution, a plurality of label frames are provided on one side of the placement frame, and a plurality of writing boards corresponding one-to-one with the card holes are provided on the outer side of the label frames.

[0016] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] This utility model discloses a placement rack for enzyme immunoassay diagnostic reagent testing, comprising a base with symmetrically arranged clamps on both sides of the base, and a placement frame between corresponding clamps. The placement frame includes an upper fixing plate, a middle fixing plate, and a lower fixing plate. The upper and middle fixing plates each have a locking hole for accommodating test tubes. The upper part of the lower fixing plate has a locking groove adapted to the bottom of the test tube. The upper part of the upper fixing plate has a cover, and the top of the upper fixing plate has several fixing posts. The cover has insertion holes adapted to the fixing posts. The multi-layered fixing plates, combined with the locking holes and grooves, provide multi-directional stability and restraint for the test tubes from the top, middle, and bottom, effectively preventing the test tubes from tipping over or falling during testing due to collisions or shaking. The cover, through the cooperation of the fixing posts and insertion holes, stably covers the upper fixing plate, preventing external dust and impurities from falling into the test tubes, ensuring reagents are not contaminated, and also preventing loss or impact on the testing environment due to accidental spillage of reagents.

[0018] The top of the upper fixing plate of this invention is provided with several crisscrossing fixing grooves. A partition is provided within each fixing groove, and several retaining plates adapted to the fixing grooves are provided on the outer side of each partition and between adjacent partitions. The cooperation of the partitions and retaining plates can enclose each test tube into a separate area, avoiding contamination between different samples and ensuring the accuracy of the test results. Furthermore, for batch testing, the number of retaining plates can be reduced as needed, integrating into multi-hole testing. Single-tube testing and batch testing can be switched by removing / installing retaining plates, making it more adaptable.

[0019] An irregularly shaped hole is provided through the clamping plate and the middle fixing plate. A fixing rod is installed within the irregularly shaped hole. One end of the fixing rod has a stop protrusion, and the other end of the fixing rod is connected to a threaded rod. A fixing nut is fitted onto the threaded rod. By passing the fixing rod through the irregularly shaped hole, and utilizing the cooperation of the stop protrusion, the threaded rod, and the fixing nut, the clamping plate and the middle fixing plate can be firmly connected together, enhancing the connection stability between the placement frame and the clamping plate and preventing relative displacement between the placement frame and the clamping plate during use.

[0020] The clamp is inclined from bottom to top towards the outer end of the base, with an angle of 30-60° between the clamp and the base. The inclined clamp increases the placement space, indirectly increasing the test tube capacity of the rack, which can meet the needs of testing multiple batches and types of reagents.

[0021] The clamping plates are provided in two sets, symmetrically arranged along the center line of the base, with one outer end of each of the two placement frames abutting against each other. The two sets of symmetrical clamping plates can simultaneously fix two placement frames, greatly increasing the test tube capacity of the rack and meeting the needs of multi-batch, multi-type reagent testing. The abutting arrangement of the two placement frames provides mutual support, enhancing the stability of the overall structure and preventing individual placement frames from tilting or being damaged due to excessive force. It also allows for a more compact rack layout, saving laboratory operating space.

[0022] The upper part of the base is provided with several weight-reducing holes, and the bottom of the base is provided with several anti-slip textures. The weight-reducing holes can effectively reduce the overall weight of the rack while ensuring the structural strength of the base, making it easier for operators to carry and move the rack and reducing physical exertion; the anti-slip textures on the bottom can increase the friction between the base and the placement surface, preventing the rack from sliding due to accidental contact during use, ensuring its stability, and avoiding situations such as test tubes tipping over or reagents spilling due to sliding.

[0023] The placement frame has a side plate on one side, and the inner side of the side plate abuts against the outer side of the clamping plate. The abutting fit between the side plate and the outer side of the clamping plate provides lateral support and limitation for the placement frame, further enhancing the tightness of the connection between the placement frame and the clamping plate, and preventing the placement frame from shaking or shifting in the horizontal direction. At the same time, the side plate can also prevent external objects from directly colliding with the placement frame to a certain extent, thus protecting the placement frame and extending its service life.

[0024] The top of each of the two clamping plates is equipped with a baffle, the bottom surface of which is horizontal and abuts against the upper fixing plate. The horizontal bottom surface of the baffle abuts against the upper fixing plate, which can apply downward pressure to the placement frame from above. Combined with the supporting effect of the clamping plates, the placement frame is firmly clamped between the clamping plates, preventing the placement frame from moving vertically. The baffle can also limit the top position of the placement frame, ensuring that multiple placement frames are consistent in height, making the overall structure of the placement rack more regular and facilitating unified management and operation.

[0025] The lower fixing plate is provided with several surrounding plates around its circumference. The surrounding plates can surround the lower fixing plate to form a protective barrier, which can prevent the bottom of the test tube from slipping off the edge of the lower fixing plate and provide further protection for the bottom of the test tube; at the same time, the surrounding plates can also prevent liquids and debris on the experimental table from entering the slots of the lower fixing plate, keeping the slots clean. In addition, they can also temporarily collect leaked liquids to prevent liquids from directly leaking onto the table and causing contamination of the experimental table.

[0026] The placement frame has several label frames on one side, and several writing boards corresponding to the card holes on the outer side of the label frames. The label frames can be used to place labels that identify the reagent information inside the test tubes, making it convenient for operators to quickly identify different reagents; the writing boards correspond one-to-one with the card holes, allowing for direct recording of relevant information about the test tubes (such as testing time, sample number, etc.), ensuring that the information for each test tube is clearly and accurately matched, reducing testing errors caused by information confusion, and improving the accuracy and efficiency of the testing work.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] like Figure 1-9 As shown, a placement rack for enzyme immunoassay diagnostic reagent testing includes a base 1, with clamps 2 symmetrically arranged on both sides of the base 1, and a placement frame 3 between corresponding clamps 2; the placement frame 3 includes an upper fixing plate 4, a middle fixing plate 5, and a lower fixing plate 6, the upper fixing plate 4 and the middle fixing plate 5 respectively having a locking hole 8 for accommodating test tubes 7 to pass through, the upper part of the lower fixing plate 6 having a locking groove 9 adapted to the bottom of the test tubes 7, the upper part of the upper fixing plate 4 having a cover 10, the top of the upper fixing plate 4 having a plurality of fixing posts 11, and the cover 10 having insertion holes 12 adapted to the plurality of fixing posts 11. The multi-layer fixing plate, together with the design of the card holes 8 and card slots 9, can stabilize and limit the test tube 7 from the top, middle and bottom in multiple directions, effectively preventing the test tube 7 from tipping over or falling off due to collision or shaking during the test. The cover 10 can be stably covered on the upper fixing plate 4 through the cooperation of the fixing post 11 and the insertion hole 12, which can block external dust and impurities from falling into the test tube 7, ensuring that the reagents are not contaminated, and at the same time, it can also prevent the reagents in the test tube 7 from being lost or affecting the test environment due to accidental splashing.

[0040] The top of the upper fixing plate 4 is provided with several crisscrossing fixing grooves 13. Each fixing groove 13 contains a partition 14. Several retaining plates 15, adapted to the fixing grooves 13, are provided on the outer side of each partition 14 and between adjacent partitions 14. The cooperation of the partitions 14 and retaining plates 15 can enclose each test tube 7 into a separate area, preventing contamination between different samples and ensuring the accuracy of the test results. Furthermore, for batch testing, the number of retaining plates 15 can be reduced as needed, integrating into multi-hole testing. Single-tube testing and batch testing can be switched by removing / installing retaining plates 15, making it more adaptable.

[0041] A shaped hole 16 is provided through the clamping plate 2 and the middle fixing plate 5. A fixing rod 17 is provided inside the shaped hole 16. One end of the fixing rod 17 has a stop protrusion 18, and the other end of the fixing rod 17 is connected to a threaded rod 19. The threaded rod 19 is fitted with a fixing nut 20. By passing the fixing rod 17 through the shaped hole 16, and with the cooperation of the stop protrusion 18, the threaded rod 19, and the fixing nut 20, the clamping plate 2 and the middle fixing plate 5 can be firmly connected together, enhancing the connection stability between the placement frame 3 and the clamping plate 2 and preventing relative displacement between the placement frame 3 and the clamping plate 2 during use.

[0042] The clamping plate 2 is inclined from bottom to top towards the outer end of the base 1, and the included angle between the clamping plate 2 and the base 1 is 30-60°. The inclined clamping plate 2 increases the placement space, which indirectly increases the capacity of the test tubes 7 of the rack, and can meet the needs of testing multiple batches and types of reagents.

[0043] The clamping plates 2 are provided in two sets, which are symmetrically arranged along the center line of the base 1, and the outer ends of the two placement frames 3 are abutted together. The two sets of symmetrical clamping plates 2 can fix two placement frames 3 at the same time, which greatly increases the test tube 7 capacity of the rack and can meet the needs of testing multiple batches and types of reagents. The outer ends of the two placement frames 3 are abutted together, which can support each other, enhance the stability of the overall structure, and prevent a single placement frame 3 from tilting or being damaged due to excessive force. At the same time, it can also make the layout of the rack more compact and save laboratory operating space.

[0044] The upper part of the base 1 is provided with several weight-reducing holes 21, and the bottom of the base 1 is provided with several anti-slip textures 22. The weight-reducing holes 21 can effectively reduce the overall weight of the rack while ensuring the structural strength of the base 1, making it easier for operators to carry and move the rack and reducing physical exertion; the anti-slip textures 22 on the bottom can increase the friction between the base 1 and the placement surface, preventing the rack from sliding due to accidental contact during use, ensuring its stability, and avoiding situations such as test tubes 7 tipping over or reagents spilling due to sliding.

[0045] The placement frame 3 has a side plate 23 on one side, and the inner side of the side plate 23 abuts against the outer side of the clamping plate 2. The abutting fit between the side plate 23 and the outer side of the clamping plate 2 can provide lateral support and limit the placement frame 3, further enhancing the tightness of the connection between the placement frame 3 and the clamping plate 2, and preventing the placement frame 3 from shaking or shifting in the horizontal direction; at the same time, the side plate 23 can also prevent external objects from directly colliding with the placement frame 3 to a certain extent, thus protecting the placement frame 3 and extending its service life.

[0046] The top of each of the two clamping plates 2 is provided with a baffle 24, the bottom surface of which is horizontal and abuts against the upper fixing plate 4. The bottom surface of the horizontal baffle 24 abuts against the upper fixing plate 4, which can apply downward pressure to the placement frame 3 from above. Combined with the supporting effect of the clamping plates 2, the placement frame 3 is firmly clamped between the clamping plates 2, preventing the placement frame 3 from moving in the vertical direction. The baffle 24 can also limit the top position of the placement frame 3, ensuring that multiple placement frames 3 are consistent in height, making the overall structure of the placement rack more regular and facilitating unified management and operation.

[0047] The lower fixing plate 6 is provided with several surrounding plates 25. The surrounding plates 25 can surround the lower fixing plate 6 to form a protective barrier, which can prevent the bottom of the test tube 7 from slipping off the edge of the lower fixing plate 6 and provide further protection for the bottom of the test tube 7; at the same time, the surrounding plates 25 can also prevent liquids and debris on the experimental table from entering the slot 9 of the lower fixing plate 6, keeping the slot 9 clean. In addition, it can also temporarily collect leaked liquids to prevent liquids from directly leaking onto the table and causing contamination of the experimental table.

[0048] The placement frame 3 has several label frames 26 on one side, and several writing boards 27 corresponding one-to-one with the card holes 8 on the outer side of the label frames 26. The slots in the label frames 26 can be used to place labels that identify the reagent information in the test tubes 7, making it convenient for operators to quickly identify different reagents; the writing boards 27 correspond one-to-one with the card holes 8, and can directly record relevant information of the test tubes 7 (such as detection time, sample number, etc.), so that the information of each test tube 7 can be clearly and accurately matched, reducing detection errors caused by information confusion and improving the accuracy and efficiency of the detection work.

[0049] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
