[0002] Urine testing is a routine test item in modern medical engineering and clinical medicine, and is one of the three major routine tests. Urine protein analyzer is a special instrument for clinical urine analysis combined with reagents made using dry chemical principles. The detection reagent changes color according to the content of several specific components in urine. The urine protein analyzer identifies the color change after the urine combines with the reagent, converts it into the component content, and outputs a test report.

[0003] Urine protein analyzers usually extract urine samples and test reagents into the test box at the same time for mixing, and then use the test reagent stirring mechanism to stir the test reagent and urine sample evenly, so that the urine sample and the test reagent react fully, so that the urine protein analyzer's test mechanism can detect it. When the urine protein analyzer's test reagent stirring mechanism is working, it is necessary to drive the stirring rod forward and lift it up and down, so that the stirring rod can be extended into or out of the test box; currently, the test reagent stirring mechanism on the existing urine protein analyzer generally requires two drive modules to realize the driving of the stirring rod to move, resulting in the overall volume of the test reagent stirring mechanism being relatively large, requiring a large space, which is not conducive to the production requirements of miniaturized equipment; moreover, the two drive modules will inevitably increase the production cost of the equipment.

[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0020] like Figure 1 , 2As shown, a detection reagent stirring mechanism of a urine protein analyzer includes a stirring mounting frame 1, on which a stirring drive motor 2 and a stirring drive wheel 3 are provided, the stirring drive wheel 3 is rotatably connected to the stirring mounting frame 1, a transmission assembly is provided on the output end of the stirring drive motor 2, the transmission assembly is connected to the stirring drive wheel 3, a stirring movable frame 4 is slidably provided on the stirring mounting frame 1, and a stirring assembly is provided on the stirring movable frame 4. A U-shaped groove 5 is provided on the stirring mounting frame 1, and a linkage rod 6 is provided on the stirring movable frame 4, which is connected to the stirring drive wheel 3 after passing through the U-shaped groove 5, and the stirring drive wheel 3 can drive the linkage rod 6 to slide in the U-shaped groove 5.

[0021] In the initial state, the linkage rod 6 is located at the rear end of the U-shaped groove 5 and is connected to the inner wall of the U-shaped groove 5, and the stirring movable frame 4 and the stirring assembly have also dropped to the limit position. When stirring is required, the stirring drive motor 2 is first used to drive the transmission assembly to move, thereby driving the stirring drive wheel 3 to rotate, and the stirring drive wheel 3 drives the linkage rod 6 to slide in the U-shaped groove 5. The U-shaped groove 5 limits the movement of the stirring movable frame 4 and the stirring assembly, thereby driving the stirring movable frame 4 and the stirring assembly to first rise, then move forward, and then drop, so that the stirring assembly is connected to the detection box, and the urine sample and the detection reagent in the detection box are stirred by the stirring assembly. After the stirring is completed, the stirring drive motor 2 is reversed, driving the stirring movable frame 4 and the stirring assembly to first rise, then move backward, and then drop to reset to the initial position.

[0022] The detection reagent stirring mechanism only needs one stirring drive motor 2 to drive the stirring component to move forward and backward and up and down, which simplifies the mechanical structure and can effectively reduce the overall volume of the detection reagent stirring mechanism, which is beneficial to the production needs of miniaturized equipment; reducing one driving module will inevitably reduce the production cost of the equipment and enhance market competitiveness.

[0023] Specifically, a linkage swing arm 7 is fixedly mounted on the stirring driving wheel 3, and the linkage swing arm 7 extends out of the side wall of the stirring driving wheel 3. A long hole 8 is provided on the linkage swing arm 7, and one end of the linkage rod 6 away from the stirring moving frame 4 extends into the long hole 8 and can slide in the long hole 8. When the stirring driving motor 2 is working, the stirring driving wheel 3 can be driven to rotate through the transmission component, and the stirring driving wheel 3 drives the linkage swing arm 7 to rotate and swing, thereby pushing the linkage rod 6 to slide in the U-shaped groove 5 through the long hole 8, so as to achieve the purpose of driving the stirring component to move up and down, forward and backward. The cooperation between the long hole 8 and the linkage rod 6 can improve the stability of the transmission and avoid the situation of motion interference.

[0024] In order to reduce the friction between the linkage rod 6 and the long hole 8, a rotary bearing 9 is sleeved on the end of the linkage rod 6 away from the stirring moving frame 4, and the outer ring of the rotary bearing 9 is slidably matched with the inner wall of the long hole 8. When the stirring drive motor 2 is working, the linkage swing arm 7 rotates and swings to push the rotary bearing 9 to rotate on the linkage rod 6, so that there is rolling friction between the long hole 8 and the rotary bearing 9; reducing the friction, it can improve the transmission efficiency and stability, and reduce the possibility of transmission jamming.

[0025] In order to limit the movement stroke of the stirring moving frame 4, a limit sensor 10 is provided on the stirring mounting frame 1. The limit sensor 10 is used to detect the rotation and swing stroke of the linkage swing arm 7. The linkage swing arm 7 can be connected to the limit sensor 10. In the initial state, the linkage swing arm 7 is connected to the limit sensor 10. After the stirring is completed, the stirring drive motor 2 drives the linkage swing arm 7 to rotate and swing with the stirring drive wheel 3 until the linkage swing arm 7 is connected to the limit sensor 10. The limit sensor 10 then feeds back a signal to control the stirring drive motor 2 to stop working; at this time, the stirring assembly also just drops and resets to the initial position. Through the cooperation of the linkage swing arm 7 and the limit sensor 10, it can be ensured that the stirring assembly can be reset to the initial position, thereby improving the accuracy of control.

[0026] In order to improve the stability of the movement of the stirring assembly, a transverse guide rail 11 is provided on the stirring mounting frame 1, a transverse slider 12 is slidably provided on the transverse guide rail 11, a lifting guide rail 13 is provided on the transverse slider 12, a lifting slider 14 is provided on the lifting guide rail 13, and the lifting slider 14 is connected to the stirring movable frame 4. The cooperation between the transverse slider 12 and the transverse guide rail 11 can limit and guide the forward or backward direction of the stirring assembly; the cooperation between the lifting slider 14 and the lifting guide rail 13 can limit and guide the lifting direction of the stirring assembly. In actual work, when the linkage rod 6 slides in the U-shaped groove 5, the transverse slider 12 and the lifting slider 14 can slide at the same time, so as to avoid interference with the movement of the linkage rod 6.

[0027] The transmission assembly includes a stirring drive wheel 15 and a stirring drive belt 16. The stirring drive wheel 15 is connected to the output end of the stirring drive motor 2, and the stirring drive belt 16 is respectively sleeved on the stirring drive wheel 3 and the stirring drive wheel 15. When working, the stirring drive motor 2 drives the stirring drive wheel 15 to rotate, thereby pulling the stirring drive belt 16 to move; the stirring drive belt 16 drives the stirring drive wheel 3 to rotate, thereby driving the linkage swing arm 7 to rotate and swing, thereby driving the stirring assembly to move forward and backward and up and down.

[0028] The stirring assembly includes a stirring motor 17, and the stirring motor 17 is connected to the stirring mobile frame 4. The output end of the stirring motor 17 is provided with a stirring rod 18. When stirring is required, the stirring drive motor 2 drives the stirring rod 18 to first rise and then move forward, and then descend and insert into the detection box of the urine protein analyzer; then the stirring motor 17 is controlled to work, and the stirring plate is driven to rotate to fully stir the detection reagent and urine sample in the detection box. After the stirring is completed, the stirring drive motor 2 is controlled to drive the stirring rod 18 to rise and then retreat, and then descend and reset to the initial position. The stirring motor 17 drives the stirring plate to rotate so as to fully stir the detection reagent and the sample, without the need for other transmission mechanisms, thereby simplifying the mechanical structure.

[0029] The stirring moving frame 4 is provided with a decorative cover 19, which is sleeved on the periphery of the stirring motor 17. By sleeve-covering the decorative cover 19 on the periphery of the stirring motor 17, foreign matter such as dust can be prevented from entering the stirring motor 17, thereby extending the service life of the stirring motor 17.

[0031] In the initial state, the linkage rod 6 is connected to the rear lower side wall of the U-shaped groove 5 , the stirring movable frame 4 and the stirring assembly also descend to the limit position, and the linkage swing arm 7 is connected to the limit sensor 10 .

[0032] When stirring is required, the stirring drive motor 2 is controlled to work, driving the stirring transmission wheel 15 to rotate, thereby pulling the stirring transmission belt 16 to move; the stirring transmission belt 16 drives the stirring drive wheel 3 to rotate, thereby driving the linkage swing arm 7 to rotate and swing; during the swinging process of the linkage swing arm 7, the long hole 8 will push the rotating bearing 9 to roll in the long hole 8, thereby driving the linkage rod 6 to slide in the U-shaped groove 5. The linkage rod 6 drives the stirring mobile frame 4, the stirring motor 17 and the stirring rod 18 to first rise and then move forward, and then descend until the stirring rod 18 is inserted into the detection box of the urine protein analyzer. After that, the stirring motor 17 is controlled to work, driving the stirring rod 18 to rotate, and the detection reagent and urine sample are fully stirred by the stirring rod 18.

[0033] After the stirring is completed, the stirring drive motor 2 is controlled to reverse, drive the stirring drive wheel 15 to rotate, and then pull the stirring drive belt 16 to move; the stirring drive belt 16 drives the stirring drive wheel 3 to rotate in the opposite direction, thereby driving the linkage swing arm 7 to rotate and swing in the opposite direction; during the swinging process of the linkage swing arm 7, the long hole 8 will push the rotating bearing 9 to roll in the long hole 8, thereby driving the linkage rod 6 to slide in the U-shaped groove 5 until the linkage swing arm 7 is connected to the limit sensor 10, and the feedback signal controls the stirring drive motor 2 to stop working. During the movement of the linkage rod 6, it will drive the stirring mobile frame 4, the stirring motor 17 and the stirring rod 18 to first rise and then retreat, and then descend, so that the stirring rod 18 will first extend out of the detection box and then retreat, descend and reset to the initial position.
