Technical Field

[0001] This utility model relates to an automatic cup rotating assembly for a coagulation analyzer, and more particularly to its driving structure, belonging to the field of detection instrument technology. Background Technology

[0002] A coagulation analyzer is an instrument used for medical examination of thrombosis and hemostasis, assessing the risk of thrombosis and bleeding, and is an essential piece of equipment for clinical diagnosis. Clinically, it is a routine medical device used to measure the content of various components in human blood, providing quantitative biochemical analysis results and offering reliable numerical evidence for the clinical diagnosis of various diseases in patients. Coagulation analyzers have sample loading, preheating, and testing stations, requiring manual transfer of samples between these stations. This results in a relatively slow testing speed. Therefore, improving the speed of sample transfer between different stations is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automatic cup rotating assembly for a coagulation analyzer.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic rotating cup assembly for a coagulation analyzer, including a push rod; the automatic rotating cup assembly for the coagulation analyzer further includes a front end plate, a rear end plate, a pair of guide rods, a lead screw, a pair of rotating seats, a nut seat, a coupling, a stepper motor, a mounting bracket, and a connecting plate; the pair of guide rods are respectively vertically connected between the front end plate and the rear end plate; the pair of rotating seats are respectively fixedly connected to the center of the front end plate and the rear end plate; the lead screw is rotatably connected to the pair of rotating seats, one end of which is connected to the output shaft of the stepper motor through a coupling, and the middle is screwed to the nut seat; the connecting plate is fixedly connected to the nut seat, and its end abuts against the guide rod; the connecting plate is fixedly connected to the end of the push rod.

[0005] A further feature of this invention is that the end of the connecting plate is a pair of sliders, which are slidably connected to the guide rod.

[0006] The present invention is further configured such that: the front end plate and the rear end plate are arranged in parallel opposite directions; a mounting bracket is connected to the front end plate, and the stepper motor is connected in the mounting bracket.

[0007] A further feature of this invention is that a reinforcing plate is connected to the side of the front end plate and the rear end plate.

[0008] The present invention is further configured such that: a sample stage is provided on the side of the guide rod, and the push rod moves parallel to the sample stage; one end of the sample stage is connected to an arc-shaped bracket; one end of the bracket is fixedly connected to the sample stage, and the other end is located directly below the guide rod.

[0009] The present invention is further configured such that: one end of the push rod is connected to the top of the connecting plate; a sample is placed on the sample stage, and the push rod and the sample are on the same horizontal plane.

[0010] Compared with existing technologies, the advantages of this invention are as follows: The lead screw is rotatably connected to a pair of rotating seats, with one end connected to the output shaft of the stepper motor via a coupling, and a nut seat screwed into the middle. The connecting plate is fixedly connected to the nut seat, and its end abuts against the guide rod. Therefore, when the stepper motor starts, it drives the lead screw to rotate via the coupling. The guide rod blocks the rotation of the connecting plate, and the nut seat connected to the connecting plate cannot rotate with the lead screw. The nut seat moves axially along the lead screw, driving the connecting plate and the push rod. The push rod pushes the sample on the sample stage to the next station. Because the stepper motor operates automatically, it is faster and more efficient than manual operation. Attached Figure Description

[0014] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0015] See appendix Figure 1-2 As shown, an automatic cup-rotating assembly for a coagulation analyzer in this embodiment includes a push rod 12; the automatic cup-rotating assembly for the coagulation analyzer also includes a front end plate 1, a rear end plate 2, a pair of guide rods 3, a lead screw 6, a pair of rotating seats 4, a nut seat 7, a coupling 8, a stepper motor 9, a mounting bracket 10, and a connecting plate 11. The pair of guide rods 3 are vertically connected between the front end plate 1 and the rear end plate 2, respectively. The pair of rotating seats 4 are fixedly connected to the centers of the front end plate 1 and the rear end plate 2, respectively. The lead screw 6 is rotatably connected to the pair of rotating seats 4, one end of which is connected to the output shaft of the stepper motor 9 through the coupling 8, and the nut seat 7 is screwed to the middle. The connecting plate 11 is fixedly connected to the nut seat 7, and its end abuts against the guide rod 3. The connecting plate 11 is fixedly connected to the end of the push rod 12.

[0016] Because the lead screw 6 is rotatably connected to a pair of rotating seats 4, one end of which is connected to the output shaft of the stepper motor 9 via a coupling 8, and the middle is screwed with a nut seat 7; the connecting plate 11 is fixedly connected to the nut seat 7, and its end abuts against the guide rod 3. Therefore, when the stepper motor 9 starts, it drives the lead screw 6 to rotate via the coupling. The guide rod 3 blocks the rotation of the connecting plate 11, and the nut seat 7 connected to the connecting plate 11 cannot rotate with the lead screw 6. The nut seat 7 moves axially on the lead screw 6, driving the connecting plate 11 and the push rod 12 to move. The push rod 12 pushes the sample on the sample stage 14 to the next station. Because the stepper motor 9 operates automatically, it is faster and more efficient than manual operation.

[0017] To reduce friction between the connecting plate 11 and the guide rod 3, this invention further comprises: a pair of sliders 5 at the end of the connecting plate 11, which are slidably connected to the guide rod 3. Changing the connection from abutting to a sliding connection reduces friction and ensures smoother operation. It also avoids the noise caused by the connecting plate 11 striking the guide rod 3.

[0018] To facilitate the installation of the stepper motor 9, this utility model is further configured such that: the front end plate 1 and the rear end plate 2 are arranged parallel to each other; a mounting bracket 10 is connected to the front end plate 1, and the stepper motor 9 is connected in the mounting bracket 10. The stepper motor 9 is connected to the front end plate 1, which is a reasonable structure and facilitates the rotation of the lead screw 6.

[0019] To improve the connection strength between the front end plate 1, the pair of guide rods 3, and the rear end plate 2, this invention further includes a reinforcing plate 15 connecting the sides of the front end plate 1 and the rear end plate 2. The reinforcing plate 15, located on the sides of the front end plate 1 and the rear end plate 2, enhances the connection strength and also avoids obstructing the movement range of the push rod 12, thus not affecting its movement.

[0020] To facilitate the pusher 12 in moving the sample on the sample stage 14, this invention is further configured as follows: a sample stage 14 is provided on the side of the guide rod 3, and the pusher 12 moves parallel to the sample stage 14; one end of the sample stage 14 is connected to an arc-shaped bracket 13; one end of the bracket 13 is fixedly connected to the sample stage 14, and the other end is located directly below the guide rod 3. One end of the pusher 12 is connected to the top of the connecting plate 11; a sample is placed on the sample stage 14, and the pusher 12 and the sample are on the same horizontal plane. The guide rod 3 and the lead screw 6 are provided in the central area of ​​the arc-shaped bracket 13. The bracket 13 avoids the guide rod 3 and the lead screw 6 and is connected to the sample stage 14. Its structure is compact and reasonable, facilitating the pusher 12 in moving the sample on the sample stage 14.

[0021] In summary, the principle of the automatic rotating cup assembly for a coagulation analyzer shown in this utility model is as follows: After the sample has finished working at this station, the stepper motor 9 is started, driving the lead screw 6 to rotate in the rotating seat 4 via the coupling. The nut seat 7 is rotatably connected to the lead screw 6 and fixedly connected to the connecting plate 11. The sliders 5 at both ends of the connecting plate 11 slide on the guide rod 3. The guide rod 3 blocks the rotation of the connecting plate 11 and the nut seat 7. The nut seat 7 can only move along the axial direction of the lead screw 6. This drives the push rod 12 to move along the axial direction of the lead screw 6. With the direction of movement of the push rod 12 parallel to the sample stage 14, the sample on the sample stage 14 is horizontally pushed to the next station. Since the sample stage 14 is connected by an arc-shaped bracket 13, the guide rod 3 and the lead screw 6 are located at the center of the arc-shaped bracket 13, avoiding the lead screw 6 and the guide rod 3. Its structure is compact, saving space, and does not affect the parallel movement of the push rod 12 and the sample stage 14.

[0022] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
