[0036] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing and simplifying the description of this application, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0038] In addition, if the term "and / or" appears, "and / or" is merely a way to describe the association relationship between associated objects, and indicates that three relationships may exist. For example, A and / or B can represent the association relationship between A and B: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that there is an "or" relationship between the associated objects before and after it. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, four, five, etc., unless otherwise clearly and specifically defined.

[0039] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integration; mechanical connections, electrical connections; direct connections, indirect connections through an intermediary, and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0042] See also Figures 1 to 5 In one embodiment of the present application, a test tube transport rack device 100 is provided for carrying and transporting test tubes (not shown). The test tube transport rack device 100 includes a transport support 10 and a rack cover 20. The rack cover 20 is replaceably mounted on the top of the transport support 10 and has test tube insertion holes 21 corresponding to the test tube slots 11.

[0043] The test tube slot 11 of the transport rack 10 of the test tube transport rack device 100 is used to accommodate test tubes. Test tubes can be inserted into the test tube slot 11 through the test tube insertion hole 21 of the rack cover 20 for transport, placement, and storage. Test tubes include not only glass test tube containers in the narrow sense (such as ordinary test tubes, supported test tubes, centrifuge test tubes, etc.), but also other containers capable of holding samples to be tested, and materials such as plastics are not specifically limited here.

[0044] As will be appreciated, the test tube transport rack device 100 can be configured with at least two different sizes of rack covers 20, each with a different shape and / or size of the test tube receptacles 21. The interchangeable rack cover 20 refers to a removable assembly between the rack cover 20 and the transport rack 10, allowing the rack cover 20 to be installed selectively. The operator can replace the rack cover 20 with a different size and install it on top of the transport rack 10 as needed.

[0045] In addition, the test tube conveyor rack device 100 may include at least two conveyor racks 10, each of which can independently hold a test tube, and each conveyor rack 10 may have at least two test tube slots 11, and all test tube slots 11 may be arranged in sequence along the longitudinal direction of the conveyor rack 10.

[0046] With the test tube rack device 100, the operator can replace the appropriate rack cover 20 based on the size of the test tube to be placed, so that the test tube insertion holes 21 of the rack cover 20 can better fit the shape and size of the target test tube. This allows the test tube rack device 100 to accommodate a wider range of test tube sizes, making the test tubes placed therein more stable and less prone to tilting or deflection.

[0047] Please also refer to Figure 6 In some embodiments, the top of the conveying bracket 10 has a first assembly structure 12, and the side of the frame cover 20 facing the conveying bracket has a second assembly structure (not shown), and the second assembly structure can be detachably matched with the first assembly structure 12.

[0048] Specifically, one of the first assembly structure 12 and the second assembly structure can be an assembly hole, and the other can be an assembly column. It can be understood that the assembly hole and the assembly column can be arranged along the height direction of the transport bracket 10 (corresponding to Figure 4 The frame cover 20 extends in the X direction as shown, and the frame cover 20 is assembled and disassembled by plugging and pulling the assembly posts relative to the assembly holes. In other words, the frame cover 20 is assembled and disassembled relative to the conveying bracket 10 by plugging and pulling.

[0049] In this way, when the frame cover 20 is assembled toward the delivery bracket 10 , the two can form a detachable connection through the cooperation between the first assembly structure 12 and the second assembly structure.

[0050] Specifically, the bottom surface of the frame cover 20 is configured with an assembly hole, and the top surface of the delivery bracket 10 is configured with an assembly post. It is understood that in other embodiments, the delivery bracket 10 and the frame cover 20 can also be detachably connected through other means, such as a snap-fit connection or a screw connection, which is not specifically limited here.

[0051] Please also refer to Figure 7 In some embodiments, the delivery bracket 10 includes a bracket body 13 and a base 14, and the bracket body 13 is arranged on the base 14. The bracket body 13 includes a bracket bottom 131 and at least two partitions 133, all of which are arranged along the longitudinal direction of the delivery bracket 10 (corresponding to the longitudinal direction of the delivery bracket 10). Figure 4 The test tube slots 11 are formed by separating the two adjacent separators 133 from each other (in the Y direction shown in FIG. 1 ).

[0052] Specifically, each transport bracket 10 may include at least three partitions 133 , and accordingly, may define at least two test tube slots 11 .

[0053] In this way, the transport rack 10 can be divided into the test tube slots 11 on the bottom plate through the partitions 133 . Meanwhile, the partitions 133 can support and limit the test tubes in the test tube slots 11 .

[0054] Furthermore, the transport bracket 10 further includes a first side plate 135 and a second side plate 137, which are arranged in the width direction of the transport bracket 10 (corresponding to the width direction of the transport bracket 10). Figure 4 In the Z direction (as shown), the first side panel 135 and the second side panel 137 are respectively disposed on opposite sides of the partition 133 and, together with the partition 133, form the test tube slot 11. The first side panel 135 has a window that communicates with the test tube slot 11, and the window can be used to observe the test tubes in the test tube slot 11.

[0055] Specifically, the first side panel 135 may include a plurality of sub-panels 1351 , and each sub-panel 1351 is connected to a corresponding partition 133 , and adjacent sub-panels 1351 are spaced apart from each other to form the above-mentioned window.

[0056] In this way, the side panels can participate in forming the test tube slots 11 and support and limit the test tubes. They can also expose the test tubes through the windows. If the test tubes are affixed with identification codes or text labels, they can also be exposed through the windows.

[0057] In some embodiments, the bottom 131 of the bracket faces the surface of the test tube slot 11, that is, the bottom of the test tube slot 11 has a positioning groove 1311. The positioning groove 1311 is used to accommodate the bottom of the test tube, which can be arc-shaped and can be specifically designed to imitate the bottom of the test tube.

[0058] In this way, the positioning groove 1311 can exert a certain restraining effect on the bottom of the test tube, thereby reducing the possibility of the bottom of the test tube moving and making the test tube more stable in the test tube slot 11 .

[0059] In some embodiments, each delivery stent 10 may include at least two sets of stent bodies 13, and all stent bodies 13 are sequentially arranged along the longitudinal direction of the delivery stent 10. It can be understood that the stent covers 20 may be arranged in a one-to-one correspondence with the stent bodies 13.

[0060] In this way, the length of a single bracket body 13 can be reduced, which helps to reduce the strength requirement and manufacturing difficulty of the single bracket body 13.

[0061] In some embodiments, the rack cover 20 includes a cover body 23 and a clamping claw 25, the clamping claw 25 has a connecting end 251 and a clamping end 253, the connecting end 251 is connected to the cover body 23, and the clamping end 253 extends into the test tube slot 11 to form a clamping space 255, and the clamping space 255 is connected to the test tube socket 21.

[0062] As can be understood, the test tube insertion hole 21 is formed in the cover 23, and the clamping ends 253 of the clamping jaws 25 surround the test tube slot 11 to form a clamping space 255, capable of exerting a clamping force on an object contained within the clamping space 255. A test tube inserted through the test tube insertion hole 21 is at least partially contained within the clamping space 255 and is held by the clamping ends 253 of the clamping jaws 25.

[0063] In this way, the clamp 25 can fix the test tube after it is inserted, and the clamp 25 itself can also be compatible with test tubes of various diameters, adaptively holding the test tube inserted into the test tube slot 11, reducing the risk of the test tube tipping over during the movement of the transport bracket 10.

[0064] Specifically, the rack cover 20 has at least two clamping jaws 25 , and the clamping ends 253 of all the clamping jaws 25 are arranged around the circumference of the test tube slot 11 and together define a clamping space 255 .

[0065] It is understandable that the clamping ends 253 of different clamping jaws 25 can be separated from each other, and each clamping jaw 25 can be deformed so that the clamping ends 253 of different clamping jaws 25 can be moved closer to or farther away from each other. The clamping jaws 25 can be elastically deformable or have a spring.

[0066] In addition, the clamping end 253 of the clamping jaw 25 may also have a contraction section. In the direction close to the bottom of the test tube groove 11, the clamping ends 253 of different clamping jaws 25 approach each other at the contraction section to facilitate the insertion of the test tube and drive the clamping ends 253 to separate from each other.

[0067] In this way, when the test tube is inserted into the clamping space 255 , the clamping ends 253 of different clamping jaws 25 can be separated from each other and elastically deformed, and the elastic force generated by the clamping jaws 25 serves as a clamping force for the test tube.

[0068] Specifically, the number of the clamping jaws 25 can be 2, 3, 4, 5, or more, and all the clamping jaws 25 are evenly distributed. In other embodiments, the clamping ends 253 of different clamping jaws 25 can also be connected by elastic members, and the frame cover 20 may not have clamping jaws 25, which is not specifically limited here.

[0069] In some embodiments, the first side wall 111 of the test tube trough 11 has two ribs 115 spaced apart and extending along the depth of the test tube trough 11. A second side wall 113 of the test tube trough 11 has an elastic pressing piece 117. The second side wall 113 is disposed opposite the first side wall 111, and the elastic pressing piece 117 extends from the second side wall 113 toward the first side wall 111.

[0070] The distance between the two ribs 115 may be smaller than the diameter of the test tube, and the extending direction of the two ribs 115 is the depth direction of the test tube slot 11 , that is, the height direction of the test tube inserted into the test tube slot 11 .

[0071] The test tube inserted into the test tube slot 11 can press the elastic pressing piece 117 located on the second side slot wall 113 , causing it to elastically deform and generate an elastic force toward the first side slot wall 111 .

[0072] It can be understood that both the ribs 115 and the elastic pressing pieces 117 can be located on the partitions 133 , and the ribs 115 on each partition 133 are arranged corresponding to the elastic pressing pieces 117 of the adjacent partitions 133 .

[0073] In this way, the elastic pressing piece 117 can press the test tube against the first side groove wall 111, so that the test tube moves toward the direction close to the first side groove wall 111. At the same time, the two ribs 115 on the first side groove wall 111 can support and restrain the test tube, thereby fixing the test tube.

[0074] When the diameter of the test tube is larger than the compatible range of the clamping claws 25 of the existing rack cover 20, the conveying bracket 10 can be replaced with a rack cover 20 without the clamping claws 25, and the elastic pressing piece 117 presses the test tube on one side, and the two ribs 115 support and fix the test tube on the other side, so that the test tube conveying rack device 100 has better compatibility.

[0075] The test tube transport rack device 100 comprises an elastic pressure piece 117, dual ribs 115, and a replaceable rack cover 20. By selecting the appropriate rack cover 20, a test tube is inserted into the test tube slot 11. The elastic pressure piece 117 and dual ribs 115 ensure adaptive centering of the test tube. Furthermore, if the rack cover 20 is equipped with gripping jaws 25, the gripping jaws 25 can also grip the test tube, improving its stability within the test tube slot 11.

[0076] Please also refer to Figure 8 In some embodiments, the test tube transport rack device 100 further includes a support base plate 30, the support base plate 30 has a sliding guide structure 31, the transport bracket 10 has a sliding fitting structure 15 that slides with the sliding guide structure 31, and the transport bracket 10 is slidably mounted on the support base plate 30 through the sliding fitting structure 15.

[0077] Among them, one of the sliding guide structure 31 and the sliding matching structure 15 can be a chute, and the other can be a slide bar. The longitudinal directions of the two are consistent, and the slide bar can slide along its longitudinal direction within the chute. Specifically, the sliding guide structure 31 can be a chute, and the sliding matching structure 15 can be a slide bar. Both are contoured designs, and the inner contour of the chute is substantially the same as the outer contour of the slide bar. The slide bar can be constructed at the bottom of the conveying bracket 10. The chute has an entrance end. The conveying bracket 10 is aligned with the entrance end of the chute by the slide bar, and moves along the longitudinal direction of both, so that the slide bar slides along the chute, thereby achieving the sliding of the conveying bracket 10 relative to the supporting base plate 30.

[0078] In this way, the transport bracket 10 can be installed on the support base plate 30 by sliding fit and be stably supported by it. In particular, when the test tube transport rack device 100 includes multiple transport brackets 10, all transport brackets 10 can be slidably installed on the same support base plate 30 in a parallel manner without interfering with each other.

[0079] Specifically, the slide is a wear-resistant, self-lubricating T-shaped slide formed on the bottom of the base 14. This helps improve the smoothness of pushing and pulling the delivery rack 10, reduces noise during entry and exit operations, and reduces the probability of the delivery rack 20 tipping over or becoming unstable. It is understood that other forms of the sliding engagement structure 15 can also be made from materials such as PPA (Polyphthalamide), PTFE (Polytetrafluoroethylene), and PEEK (Poly(ether-ether-ketone)), and this is not specifically limited here.

[0080] Furthermore, the conveying bracket 10 also has a handle 16, which can be connected to the base 14 and is located at the end of the entire conveying bracket 10, so that the operator can apply force to the conveying bracket 10 through the handle 16 to push and pull the conveying bracket 10, driving it to slide relative to the supporting base plate 30 to achieve entry, exit and disassembly.

[0081] In some embodiments, the support base 30 has at least two sliding guide structures 31, all of which are arranged parallel to each other. The test tube transport rack device 100 includes at least two transport racks 10, all of which are slidably engaged with one sliding guide structure 31 and independently slidably mounted on the support base 30.

[0082] It can be understood that all the conveying brackets 10 are respectively arranged in a one-to-one correspondence with each sliding guide structure 31, and can be individually assembled and disassembled.

[0083] In this way, the test tube transport rack device 100 can carry more test tubes, effectively improving the efficiency of equipment use, reducing the frequency of manual operation, and making it more convenient to take out test tubes individually and multiple times.

[0084] In some embodiments, the test tube transport rack device 100 further includes an in-place detection member 40 , which is disposed on the support base 30 and configured to detect whether the transport rack 10 has slid to a set position.

[0085] If the conveying bracket 10 is installed in place relative to the supporting base plate 30 , it should be in a set position, and when the conveying bracket 10 slides to the set position, the position detection member 40 can be triggered.

[0086] In this way, the operator can use the position detection member 40 to determine whether the conveying bracket 10 is installed in place relative to the support base 30, so as to improve the accuracy of the installation of the conveying bracket 10 relative to the support base 30.

[0087] Specifically, the in-position detection member 40 is a through-beam optical coupler detection member, and the conveyor bracket 10 further includes a detection block 17. When the conveyor bracket 10 slides to a set position, the detection block 17 is inserted into the detection position of the through-beam optical coupler detection member. The detection block 17 can be provided at one end of the base 14 of the conveyor bracket 10.

[0088] In addition, the support base 30 is further provided with an indicator 33, which is electrically connected to the in-position detection member 40 and is configured to emit an indication signal when the transport support 10 slides to a set position. The indicator 33 can be, but is not limited to, an in-position indicator light, and accordingly, the indication signal is the lighting of the indicator light.

[0089] In this way, when the conveying bracket 10 slides to the set position, it will trigger the opposing optical coupling detection component, at which time the signal changes, and an indication signal is sent through the indicator 33 of the supporting base plate 30 to indicate that the conveying bracket 10 in the slot is in place.

[0090] It is understandable that in some other embodiments, the in-place detection member 40 can also be other optical switches, contact switches or relays, etc., as long as it can detect whether the delivery bracket 10 is in place, and no specific limitation is made here.

[0091] In some embodiments, the transport rack 10 slides along its longitudinal direction with the sliding guide structure 31. The test tube transport rack device 100 also includes a barcode scanner 51, which is located on one side of the transport rack 10 in the longitudinal direction. The transport rack 10 has a barcode position 18, which is configured to pass through the barcode scanner 51 during the process of the transport rack 10 being slidably mounted on the support base 30.

[0092] It can be understood that the barcode scanner 51 is a barcode scanning device, which can be arranged on the supporting base plate 30 or at other positions outside the supporting base plate 30. It only needs to be located on one side of the entire conveying bracket 10 in the longitudinal direction.

[0093] The barcode position 18 is used to attach a barcode, which is recognized by the barcode scanner 51 and used to obtain information. In addition to the barcode position 18, the test tube itself can also be attached with a barcode and exposed from the window.

[0094] The barcode position 18 is located on the side of the conveying bracket 10 facing the barcode scanner 51, and the barcode scanner 51 is located at the entrance end of the slide groove of the supporting base plate 30. In this way, when the conveying bracket 10 is slidably installed relative to the supporting base plate 30 from the entrance end of the slide groove, the barcode positions 18 facing the barcode scanner 51 pass through the barcode scanner 51 one by one and are scanned by it.

[0095] In this way, the barcode scanner 51 cooperates with the barcode pasted on the barcode position 18 to improve the orderly management of the test tubes by the test tube transport rack device 100 and help to grasp the test tube information.

[0096] In some embodiments, the barcode position 18 includes a first barcode position 181 . The first barcode position 181 is located on a side of the transport support 10 facing the barcode scanner 51 and is arranged corresponding to the test tube slot 11 .

[0097] The first barcode positions 181 may be formed on the surface of the first side plate 135 and are arranged in a one-to-one correspondence with the test tube slots 11 , that is, each test tube slot 11 has a corresponding first barcode position 181 .

[0098] In this way, each first barcode position 181 can record or represent the information of its corresponding test tube slot 11 , so that the operator can manage the test tubes in each test tube slot 11 according to the information.

[0099] In some embodiments, the barcode position 18 includes a second barcode position, which is located on a side of the conveying bracket 10 facing the barcode scanner 51 and at one end of the conveying bracket 10 in the longitudinal direction.

[0100] The second barcode position may be located at the front end or the rear end of each delivery stent 10 , and each second barcode position corresponds to one delivery stent 10 .

[0101] In this way, the second barcode can record or indicate the information of the delivery stent 10 in which it is located, so that the operator can manage different delivery stents 10 according to the information.

[0102] Specifically, each conveyor rack 10 has 20 test tube slots 11, and 21 barcode positions 18 are designed on the conveyor rack 10, 20 of which are first barcode positions 181, which are used to mark the test tubes placed in the 20 test tube slots 11. The end of the conveyor rack 10, that is, the end of the handle 16, has a second barcode position for marking the conveyor rack 10.

[0103] In some embodiments, the plane where at least some of the barcode positions 18 are located intersects with the longitudinal direction of the delivery stent 10 .

[0104] Specifically, the planes where all the first barcode positions 181 are located intersect with the longitudinal direction of the conveying bracket 10 , and the direction of the barcode scanner 51 is perpendicular to the longitudinal direction of the conveying bracket 10 .

[0105] The surface of each sub-plate 1351 of the first side plate 135 forms a first barcode position 181, and all sub-plates 1351 are inclined relative to the longitudinal direction of the conveying bracket 10, that is, the surfaces of all sub-plates 1351 forming the first barcode position 181 intersect with the longitudinal direction of the conveying bracket 10.

[0106] In this way, the barcode position 18 of the conveying bracket 10 is set to a certain deflection angle to reduce the influence of light reflection on the signal received by the scanner 51.

[0107] In some embodiments, the barcode scanner 51 has a zoom function. The test tube transport rack device 100 further includes a rangefinder 53 located on one side of all transport racks 10 in the longitudinal direction and configured to detect the distance between the rangefinder 53 and the transport rack 10 toward which the barcode scanner 51 is directed.

[0108] It can be understood that the rangefinder 53 can be connected to the scanner 51 for communication, and the distance measured by it and the conveying bracket 10 can represent the distance between the scanner 51 and the conveying bracket 10 that the scanner 51 is facing, thereby helping the scanner 51 with zoom function to focus.

[0109] The communication connection may be a direct communication connection between the rangefinder 53 and the barcode scanner 51 , or an indirect communication connection through other data processing modules, controllers, etc. The connection method may be wired or wireless.

[0110] In this way, when different transport racks 10 are installed, the scanner 51 can use the distance measurement of the rangefinder 53 combined with its own zoom to align with the transport racks 10 at different distances, thereby improving the accuracy and efficiency of recognition. In addition, with the help of the rangefinder 53, different transport racks 10 can also be distinguished.

[0111] In some embodiments, the test tube transport rack device 100 further includes a mounting cover plate 55 , which is located on one side of the supporting base plate 30 and is used to mount a barcode scanner 51 and a rangefinder 53 .

[0112] In some embodiments, the handle 16 is formed with a code scanning avoidance space 161 . After the delivery bracket 10 is installed in place, the code scanner 51 faces the code scanning avoidance space 161 .

[0113] It can be understood that after the conveying bracket 10 is installed in place, its code scanning avoidance space 161 can avoid the direction of the code scanner 51 and does not block the code scanner 51.

[0114] In addition, the handle 16 adopts an ergonomic design and does not interfere with adjacent components. Specifically, it can be a "U"-shaped or "L"-shaped structure.

[0115] In this way, the transport bracket 10 installed in place avoids the barcode scanner 51 through the barcode scanning avoidance space 161 to avoid blocking it and affecting the scanning of barcodes on other transport brackets 10.

[0116] In addition to the barcode scanner 51 and rangefinder 53, the test tube transport rack device 100 can also utilize a positioning and recognition management system using a chip embedded in the transport rack 10 or a visual positioning and recognition management system using a camera. The operator can freely place a test tube into any test tube slot 11 of any transport rack 10, and the device accurately determines the test tube's position using the barcode scanner 51 and rangefinder 53. Combining the barcode scanner 51's recognition of the barcode at barcode position 18 with the installation process of pushing the transport rack 10 into place eliminates the need for secondary scanning after removing the test tube, thereby improving the efficiency and success rate of code scanning.

[0117] In some embodiments, the delivery bracket 10 further includes a positioning structure 19 , and the support base 30 has a positioning and matching structure 35 . When the delivery bracket 10 slides to a set position, the positioning structure 19 engages with the positioning and matching structure 35 .

[0118] It can be understood that after the positioning structure 19 is engaged with the positioning matching structure 35 , a limit can be generated in the sliding direction of the conveying bracket 10 .

[0119] Thus, when the operator pushes the transport rack 10 for installation and feels the positioning structure 19 engage with the positioning and mating structure 35, it indicates that the transport rack 10 has reached the set position and is properly installed. In other words, the positioning structure 19 and the positioning and mating structure 35 effectively position the transport rack 10 in the correct position, ensuring that the test tube is analyzed in the correct position and making it easier to access the transport rack 10. Furthermore, once the transport rack 10 is properly installed, the engagement of the positioning structure 19 and the positioning and mating structure 35 ensures that the transport rack 10 remains stably in the set position.

[0120] Specifically, the positioning structure 19 is a snap-fitting groove provided at the top of the detection block 17, and the positioning and matching structure 35 is a ball plunger. After the delivery rack 10 is installed in place, the ball plunger snaps into the snap-fitting groove. The ball plunger positioning also has an anti-collision effect, which can reduce the probability of collision of the delivery rack 10, better protect the safety of the test tube, and prevent it from slipping out and falling.

[0121] It is understandable that in some other embodiments, the delivery bracket 10 may also be positioned relative to the support base 30 using positioning pins or other positioning clamps.

[0122] The above-mentioned test tube conveyor rack device 100 includes a conveyor rack 10, a rack cover 20, a support base 30, an in-place detection member 40, an indicator 33, a barcode scanner 51 and a rangefinder 53. In addition, the test tube conveyor rack device 100 may also include an end vertical plate 60 and a board support plate 70, wherein the end vertical plate 60 can be used to install the in-place detection member 40 and the ball plunger, and the card support plate is used to install the board. The conveyor rack 10 is loaded into the support base 30 through a T-slot-shaped sliding guide structure 31. During the loading process, the corresponding barcode information on the conveyor rack 10 is read by the barcode scanner 51 and the rangefinder 53. The in-place detection and positioning of the conveyor rack 10 are completed by the ball plunger, the in-place detection member 40, etc. The detection block 17 of the conveyor rack 10 is inserted into the detection position of the in-place detection member 40, causing the signal to change, and the indicator 33 on the support base 30 indicates that the corresponding conveyor rack 10 is in place. At the same time, the conveyor rack 10 engages with the ball plunger on the end plate 60 through the locking groove on the detection block 17, effectively securing the conveyor rack 10 and ensuring that the test tube is correctly positioned for analysis. The zoom scanner 51 and rangefinder 53 work together to insert the conveyor rack 10's slider into the slot. This process, combined with the scanning function of the scanner 51, reduces the need for rescanning after test tube removal and improves test tube storage security. To improve the success rate of barcode scanning, the barcode position 18 of the conveyor rack 10 is set with a certain deflection angle to reduce the impact of light reflection on the signal received by the scanner 51. Simultaneously, the rangefinder 53 reads the corresponding test tube slot and distinguishes the information of different test tubes in different slots. To secure the test tubes, the rack cover 20 includes a cover body 23 and four clamping jaws 25, which are symmetrically arranged within the test tube slot 11, compatibility with test tubes of various diameters and excellent versatility. In addition, the operator can also replace the rack cover 20 according to the different test tube diameters to make the test tube transport rack device 100 more compatible. When the diameter of the test tube used is larger than the compatible range of the clamping jaws 25, the rack cover 20 without the clamping jaws 25 can be replaced. Then, the test tube is fixed by using a single-sided compression of the elastic pressure piece 117 on one side and a double rib 115 on the other side for support.

[0123] The sliding fit structure 15 is a wear-resistant, self-lubricating T-shaped slide made of POM (Polyformaldehyde). This helps improve the smoothness of pushing and pulling the delivery rack 10, reduces noise levels during sample loading and unloading operations, and prevents the delivery rack 10 from tipping over or becoming unstable. Furthermore, the delivery rack 10 features a comfortable, ergonomic handle 16. The "7"-shaped handle 16 has a clear space 161 for scanning QR codes. The extended handle design does not obstruct the indicator 33 and does not interfere with adjacent components.

[0124] In some embodiments, the test tube transport rack device 100 further includes a static electricity removal component, which includes a first conductive member 81 . The first conductive member 81 is disposed on the support base 30 and is configured to be electrically connected to the bracket body 13 .

[0125] The first conductive member 81 is electrically connected to the support body 13 and can conduct static electricity carried by the support body 13 and the test tube to the outside, for example, to the support base plate 30 and further to ground.

[0126] Thus, the holder body 13 is made of a conductive material, and the first conductive member 81 can dissipate static electricity between the holder body 13 and the test tube, effectively controlling static electricity accumulation and reducing damage to electronic components caused by static electricity. Furthermore, static electricity removal helps reduce adhesion and accumulation between samples and test tubes, between test tubes and the holder body 13, and between test tubes, thereby improving the operating efficiency of the test tube transport rack device 100.

[0127] In some embodiments, the first conductive member 81 is embedded in the surface of the support base 30 facing the conveying bracket 10 and is configured to be conductively connected to the bracket body 13 when the conveying bracket 10 is in a set position.

[0128] In other words, when the conveying bracket 10 slides to the set position on the supporting base 30 and is installed in place, the first conductive member 81 is electrically connected to the bracket body 13. The surface of the supporting base 30 facing the conveying bracket 10 may have a first groove for installing the first conductive member 81.

[0129] In this way, the operator only needs to push the conveying bracket 10 into place to complete the installation, and the first conductive member 81 will be synchronously conductively connected to the bracket body 13 to achieve static electricity removal without the need for additional operations.

[0130] In some embodiments, the static electricity removal assembly further includes a second conductive member 83, which is embedded in the surface of the base 14 facing the support base 30 and electrically connected to the bracket body 13. When the transport bracket 10 is in the set position, the second conductive member 83 contacts the first conductive member 81.

[0131] It can be understood that the first conductive member 81 is embedded in the surface of the support base 30 facing the conveying bracket 10, which means that the first conductive member 81 can be exposed on the surface of the support base 30 facing the conveying bracket 10, and the second conductive member 83 is embedded in the surface of the base 14 facing the support base 30, which means that the second conductive member 83 can be exposed on the surface of the base 14 facing the support base 30. When the conveying bracket 10 is in the set position, the exposed areas of the two at least partially overlap and form contact with each other, forming a conductive connection. The surface of the base 14 facing the support base 30 may have a second groove, and the second groove is used to mount the first conductive member 81.

[0132] In this way, the operator only needs to push the delivery bracket 10 into place and install it, and the bracket body 13 can form an electrical connection with the first conductive member 81 through the second conductive member 83 contacting the first conductive member 81.

[0133] Furthermore, the first conductive member 81 is an elastic member and abuts the second conductive member 83 when the conveying bracket 10 slides to the set position; and / or the second conductive member 83 is an elastic member and abuts the first conductive member 81 when the conveying bracket 10 slides to the set position.

[0134] In other words, at least one of the first conductive member 81 and the second conductive member 83 is an elastic member, wherein the elastic member can be but is not limited to a metal spring, a metal spring, etc., and one of the first conductive member 81 and the second conductive member 83 as an elastic member can abut against the other through its own elastic force.

[0135] In this way, after the delivery bracket 10 is installed in place, the first conductive member 81 and the second conductive member 83 can be in close contact with each other by means of elastic force, thereby improving the stability of the electrical connection between the two.

[0136] Furthermore, the delivery bracket 10 is moved along the first direction (corresponding to Figure 1 The first conductive member 81 is a conductive spring with one end in the first direction being fixed and the other end being free. The fixed end is connected to the support base 30. In the first direction, the first conductive member 81 is arranged in an upward slope. The fixed end can be fixed to the support base 30 via screws.

[0137] The direction in which the conveying bracket 10 slides from the entrance end of the sliding guide structure 31 to the set position is the first direction, that is, the conveying bracket 10 is installed in place by sliding to the set position along the first direction.

[0138] It can be understood that the free end of the first conductive member 81 can move through the elastic deformation of the first conductive member 81, and is further away from the entrance end of the sliding guide structure 31 than the fixed end. The first conductive member 81 is at least partially tilted, and its free end is higher than the fixed end.

[0139] In this way, the first conductive member 81 forms an inclined guide surface. As the conveyor bracket 10 slides, the conveyor bracket 10 gradually contacts the first conductive member 81 and presses down on the first conductive member 81, causing it to elastically deform. Under the action of the elastic force, the first conductive member 81 presses against the conveyor bracket 10 until the first conductive member 81 slides until it contacts the second conductive member 83.

[0140] In some embodiments, the transport rack 10 further includes a connector 110, which is made of a conductive material and extends from the side of the base 14 facing the support base 30 to the side of the base 14 facing away from the support base 30. The rack body 13 is connected to the side of the base 14 facing away from the support base 30 via the connector 110, and the second conductive member 83 contacts the connector 110 on the side of the base 14 facing the support base 30.

[0141] Specifically, the connecting member 110 passes through the second conductive member 83 and fixes it to the bottom of the base 14 . The connecting member 110 may be, but is not limited to, a screw, a rivet, or the like.

[0142] In this way, the connector 110 fixes the bracket body 13 while electrically connecting the bracket body 13 located above the base 14 and the second conductive member 83 located below the base 14 .

[0143] In some embodiments, each delivery bracket 10 includes at least two sets of bracket bodies 13 , and all bracket bodies 13 are disposed on a base 14 along the longitudinal direction of the delivery bracket 10 .

[0144] In this way, the length of a single bracket body 13 can be reduced, which helps to reduce the strength requirement and manufacturing difficulty of the single bracket body 13.

[0145] Furthermore, all the support bodies 13 of each transport support 10 are connected to the base 14 via connectors 110. The static electricity removal assembly further includes a third conductive member 85, which is in contact with the connectors 110 connecting two adjacent groups of support bodies 13.

[0146] Specifically, the connecting member 110 passes through the third conductive member 85 and is fixed to the bottom of the base 14 . The bottom of the base 14 may form a third groove for mounting the third conductive member 85 .

[0147] In this way, the third conductive element 85 connects all the bracket bodies 13 in series, and enables the bracket bodies 13 farther from the first conductive element 81 to be electrically connected to the first conductive element 81 through the remaining bracket bodies 13 .

[0148] The above-mentioned test tube conveying rack device 100 has a plurality of conveying brackets 10 for conveying test tubes, and all the conveying brackets 10 are independently slidably installed on the support base plate 30 through a sliding fitting structure 15. The conveying bracket 10 has a base 14, and at least two groups of bracket bodies 13 are provided on the base 14. The bracket bodies 13 are made of conductive material and are connected to the base 14 through conductive connectors 110. There is a first conductive member 81 on the support base plate 30. In the first direction, the first conductive member 81 is configured to be arranged with an upward slope. During the sliding process of the conveying bracket 10, the conveying bracket 10 gradually contacts the first conductive member 81 and presses down the first conductive member 81 to cause it to undergo elastic deformation. Under the action of the elastic force, the first conductive member 81 will press against the conveying bracket 10 until the first conductive member 81 slides to contact the second conductive member 83. The second conductive member 83 is fixed to the base 14 via the connector 110 and is also electrically connected to the support body 13 via the connector 110. All support bodies 13 of the same transport support 10 are connected in series via the third conductive member 85. In this way, static electricity on the test tube can be transmitted to the second conductive member 83 through the support body 13 and then discharged outward through the first conductive member 81, which is in tight elastic contact with the second conductive member 83. The first conductive member 81 can be grounded, thereby eliminating static electricity from the test tube and the support body 13. The conductive material can be a metal material, and the first conductive member 81, the second conductive member 83, the third conductive member 85, and the connector 110 can all be treated to remove the oxide layer at least in the areas where contact and electrical conduction are required.

[0149] A single transport rack 10 of the test tube transport rack device 100 integrates 20 test tube slots 11, which can hold 20 PCS of samples at a time, effectively improving the efficiency of equipment use and reducing the frequency of manual operation. Secondly, the test tube placement position is designed with a rack cover 20 with a clamp 25. After the test tube is placed, the test tube can be adaptively clamped to reduce the risk of tipping over during the movement of the transport rack 10. At the same time, when the test tube diameter is too large, the transport rack 10 can also be supported and fixed by the elastic pressing piece 117 and the double ribs 115, thereby improving its compatibility. In addition, 21 barcode positions 18 are designed on the transport rack 10, 20 of which are used to mark the 20 test tubes placed, and the last barcode near the handle 16 is used to mark the transport rack 10. In this way, the operator can arbitrarily place the test tube into any test tube slot 11 of any transport rack 10, and the device can accurately determine the position of the test tube through the barcode scanner 51 and the rangefinder 53. Furthermore, the test tube rack device 100 can also remove static electricity from the rack body 13 and the test tubes within it through a static removal component. This improves the convenience of using the test tube rack device 100 for multiple test tubes, reduces the risk of test tubes tipping over, and allows for more organized test tube management in experiments where multiple test tubes are used simultaneously.

[0150] The present application also provides a detection device, including the above-mentioned test tube conveying rack device 100. Specifically, the detection device can be, but is not limited to, a luminescent immunoassay analyzer.

[0151] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0152] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
