Description

Technical Field

[0001] This utility model relates to the field of sample loading arm technology, specifically a multi-reagent-position rotary sample loading arm for an immunoassay analyzer. Background Technology

[0002] An immunoassay analyzer is a medical testing device based on immunological principles used to detect specific biomarkers (such as antigens, antibodies, hormones, tumor markers, etc.) in human body fluids (such as serum, plasma, urine, etc.).

[0003] Publication number "CN215180276U" discloses a sampling arm device, including a mounting frame and a rotating shaft mounted on the mounting frame. A cantilever is fixedly connected to the upper end of the rotating shaft, and a sampling needle is connected to the end of the cantilever away from the rotating shaft. The mounting frame is equipped with a first power device for driving the rotating shaft to reciprocate and a second power device for driving the rotating shaft to move up and down reciprocally. The first power device is a stepper motor, which is connected to the rotating shaft via a first synchronous belt. A linear bearing and a bearing housing are mounted on the rotating shaft. A rotating seat, a first baffle, a second synchronous pulley, and a first bearing are sequentially mounted on the outer side of the bearing housing. Increasing the length of the linear bearing ensures the stability of the rotating shaft during vertical and rotational movements. Using a linear bearing, a first side plate, and a connecting block to jointly drive the rotating shaft increases the connection area with the rotating shaft, improving the stability of the rotating shaft's movement.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] In the multi-position rotary sample arm of an immunoassay analyzer, the drive box is the core power component. Its integrated drive structure directly controls the rotational accuracy of the sample arm and the stability of the sample dispensing action, playing a crucial role in ensuring the accuracy of the immunoassay results. However, when it is necessary to repair the parts inside the drive box, the existing sample arm drive boxes mostly use traditional connection methods such as bolt fastening. Disassembly requires the use of special tools such as wrenches to tighten the fasteners one by one, making the operation cumbersome. Utility Model Content

[0006] To address the problem of cumbersome disassembly of the driver box, the purpose of this invention is to provide a multi-reagent-position rotary sample dispensing arm for an immunoassay analyzer.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a multi-reagent-position rotary sample dispensing arm for an immunoassay analyzer, comprising a sample dispensing arm body, a rotating shaft movably provided on the top of the sample dispensing arm body, a drive box fixedly installed on the top of the rotating shaft, a disassembly and assembly mechanism provided on the outside of the drive box for quick disassembly and assembly of the drive box, and a linkage mechanism provided at the bottom of the disassembly and assembly mechanism to improve the ease of use of the disassembly and assembly mechanism.

[0008] The drive box includes a first box and a second box. The disassembly and assembly mechanism includes two connecting plates fixedly connected to the second box. A positioning plate is fixedly installed at the bottom of the connecting plate. A positioning groove is opened at the bottom of the positioning plate. Hollow plates are symmetrically distributed and fixedly installed on the outside of the first box. A pull plate is provided on the outside of the hollow plate. A locking plate is fixedly installed on the outside of the pull plate. The locking plate is movably locked inside the hollow plate. Connecting rods are symmetrically distributed and fixedly installed on the outside of the pull plate. The connecting rods pass through one side of the hollow plate. The connecting rods and the inner wall of the hollow plate are fixedly connected by springs.

[0009] Preferably, the linkage mechanism includes an extension plate fixedly connected to two pull plates. The two extension plates are distributed diagonally. A rack is fixedly installed on the opposite side of each extension plate. A gear is meshed on the opposite side of the two racks. A rotating shaft is movably installed in the middle of the gear. The rotating shaft is fixedly connected to the first housing.

[0010] Preferably, a support plate is fixedly installed at the bottom of the first box body, and the support plate has a slot inside, with the two extension plates located in their respective slots.

[0011] Preferably, an arc-shaped plate is fixedly installed at the bottom of the second box, and an arc-shaped groove is opened at the top of the first box, with the arc-shaped plate movably engaged in the arc-shaped groove.

[0012] Preferably, a viewing window is fixedly installed at the top of the second box, and the viewing window is made of transparent material.

[0013] Preferably, the extension plates are distributed in an L-shape, and symmetrically distributed mounting holes are provided at the bottom of the extension plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This application enables rapid assembly and disassembly of the drive box via a disassembly and assembly mechanism, improving maintenance convenience. During assembly and disassembly, pulling the pull plate moves the clamping plate and connecting rod, compressing the spring. The second box body then fits against the first box body, allowing the positioning plate to enter the hollow plate. Releasing the pull plate releases the spring, causing the clamping plate to pass through the positioning groove, completing the fixation. During disassembly, pulling the pull plate disengages the clamping plate from the positioning groove. This mechanism requires no complex tools and achieves rapid assembly and disassembly of the drive box through mechanical structure cooperation, facilitating the inspection of internal components, reducing maintenance time, and ensuring equipment operating efficiency.

[0016] 2. This application improves the ease of operation of the assembly and disassembly mechanism and reduces the difficulty of operation by using a linkage mechanism. When the pull plate in the linkage mechanism moves, it drives the extension plate and rack to move. The rack drives another rack to move in the opposite direction through meshing with the gear, so that the pull plates on both sides of the first box move synchronously. There is no need to operate the pull plates on both sides separately. The synchronous movement of the two plates can be achieved by pulling on one side only, which simplifies the operation steps and saves labor costs. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model discloses a multi-reagent-position rotary sample dispensing arm for an immunoassay analyzer, and provides the following two embodiments:

[0025] Example 1: A multi-reagent-position rotary sample dispensing arm for an immunoassay analyzer includes a sample dispensing arm body 101, a rotating shaft 102 movably disposed on the top of the sample dispensing arm body 101, a drive box 103 fixedly mounted on the top of the rotating shaft 102, and a disassembly and assembly mechanism 1 disposed on the outside of the drive box 103 for quick disassembly and assembly of the drive box 103. At the same time, a linkage mechanism 2 is disposed at the bottom of the disassembly and assembly mechanism 1 to improve the ease of use of the disassembly and assembly mechanism 1.

[0026] The drive box 103 includes a first box body 11 and a second box body 12. The disassembly and assembly mechanism 1 includes two connecting plates 13 fixedly connected to the second box body 12. A positioning plate 14 is fixedly installed at the bottom of the connecting plate 13. A positioning groove 15 is opened at the bottom of the positioning plate 14. Hollow plates 16 are symmetrically distributed and fixedly installed on the outside of the first box body 11. A pull plate 17 is provided on the outside of the hollow plate 16. A locking plate 18 is fixedly installed on the outside of the pull plate 17. The locking plate 18 is movably locked inside the hollow plate 16. A connecting rod 19 is symmetrically distributed and fixedly installed on the outside of the pull plate 17. The connecting rod 19 passes through one side of the hollow plate 16. The connecting rod 19 and the inner wall of the hollow plate 16 are fixedly connected by a spring 191.

[0027] Example 2 differs from Example 1 in that the linkage mechanism 2 includes an extension plate 21 fixedly connected to two pull plates 17. The two extension plates 21 are diagonally distributed. A rack 22 is fixedly installed on the opposite side of each extension plate 21. A gear 23 is meshed on the opposite side of the two racks 22. A rotating shaft 24 is movably installed in the middle of the gear 23. The rotating shaft 24 is fixedly connected to the first box body 11.

[0028] A support plate 31 is fixedly installed at the bottom of the first box 11. The support plate 31 has a slot 32 inside. The two extension plates 21 are located in their respective slots 32. The support plate 31 can support the extension plates 21 and improve their stability.

[0029] An arc-shaped plate 41 is fixedly installed at the bottom of the second box 12, and an arc-shaped groove 42 is opened at the top of the first box 11. The arc-shaped plate 41 is movably locked in the arc-shaped groove 42. By setting the arc-shaped plate 41, the connection between the first box 11 and the second box 12 is made tighter, and the stability of the installation is enhanced.

[0030] A viewing window 51 is fixedly installed on the top of the second box 12. The viewing window 51 is made of transparent material. By setting up the viewing window 51, the staff can view the working status of the internal components of the drive box 103 in real time and quickly take measures to inspect, maintain or replace the components to avoid the failure from spreading and affecting the overall operating efficiency of the equipment.

[0031] The extension plate 21 is distributed in an L-shape, and the bottom of the extension plate 21 has symmetrically distributed mounting holes 61. By setting the mounting holes 61, it is convenient for workers to install the extension plate 21 and the rack 22 with fixing screws.

[0032] Working principle: In actual use, when the drive box 103 needs to be assembled, by pulling the pull plate 17, it causes the clamping plate 18 and connecting rod 19 to move away from the hollow plate 16. While the connecting rod 19 is moving, it compresses the spring 191. At the same time, the pull plate 17 can drive the extension plate 21 to move. The extension plate 21 drives the rack 22 to move, so that the rack 22 drives another rack 22 to move in the opposite direction through the gear 23, thereby allowing the first box 11 to move away from the hollow plate 16. The pull plate 17 on the other side moves, and then the second box 12 and the first box 11 are brought together, so that the positioning plate 14 enters the hollow plate 16. At this time, the pulling force on the pull plate 17 is stopped, the spring 191 releases its elastic force, and drives the two pull plates 17 to reset. At the same time, the locking plate 18 passes through the positioning groove 15 to fix the positioning plate 14 and the second box 12. When it is necessary to remove the first box 11 and the second box 12, the pull plate 17 is pulled to disengage the locking plate 18 from the positioning groove 15.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
