Therefore, accurate stability testing is crucial. Currently, suspension stability testing is mainly achieved through static observation. However, the traditional static method is too time-consuming and has low testing efficiency, failing to meet the need for rapid testing. Therefore, a suspension stability testing device is proposed.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-5 A suspension stability testing device includes a rectangular stage 21, a rotating stage above the rectangular stage 21, and a placement slot 3 on the top of the rotating stage. A sample tube is placed in the placement slot 3. By rotating the rotating stage, it is convenient to place the sample tube containing the suspension into the placement slot 3 in sequence, and it is also convenient to test the stability of the suspension by the centrifugal force of the rotation during the test. It should be noted that the sample tube is transparent, making it easy to observe the suspension sample inside.

[0016] A top plate 4 is provided above the sample tube. Before testing, the top plate abuts against the top of the sample tube to prevent the sample tube from falling out of the placement slot 3.

[0017] A rectangular shell 5 is provided above the rectangular stage 21, and a sliding block 6 is provided above the rectangular stage 21. A shaking mechanism is provided on the rectangular stage 21, which drives the rotating stage to shake back and forth through the sliding block 6. Through the shaking mechanism, the sliding block 6 drives the rotating stage to shake back and forth, thereby enabling the stability testing of the suspension in several sample tubes on the rotating stage.

[0018] The swaying mechanism includes a first rotating rod 8 rotatably connected to a rectangular platform 21. A rotating plate 9 is fixedly connected to one end of the first rotating rod 8. A connecting column 10 is fixedly connected to one side of the rotating plate 9. A limit block 11 is fixedly connected to one end of the connecting column 10. A connecting ring 12 is sleeved on the connecting column 10. A connecting block is fixedly connected to one side of the connecting ring 12. The connecting block is fixedly connected to a sliding block 6. A limit frame 13 is fixedly connected to the top of the rectangular platform 21. The sliding block 6 is slidably connected to the limit frame 13. By rotating the rotating plate 9, the connecting column 10 drives the connecting ring 12 to move. The connecting ring 12 then slides back and forth along the limit frame 13 via the sliding block 6, thereby allowing the rotating platform to sway back and forth.

[0019] The two sides of the connecting ring 12 are respectively attached to the rotating plate 9 and the limiting block 11, and the connecting ring 12 between the rotating plate 9 and the limiting block 11 can move back and forth stably.

[0020] The top of the sliding block 6 has a circular groove, in which a second drive motor 14 is installed. The output end of the second drive motor 14 is connected to a second rotating rod 15. One end of the second rotating rod 15 is fixedly connected to the bottom of the rotating table. By rotating the second rotating rod 15, the rotating table can drive multiple sample tubes to rotate. This avoids the need to pick up and put down the sample tubes while the shaking mechanism drives the sample tubes to shake, thus rotating the rotating table and further improving the efficiency of stability detection. A rectangular groove is provided in the placement groove 3, and a spring is fixedly connected in the rectangular groove. A trapezoidal block 16 is fixedly connected to one end of the spring. The trapezoidal block 16 is in contact with the sample tube. Through the elasticity of the spring, the trapezoidal block 16 clamps the sample tube in the placement groove 3, so as to prevent the sample tube from falling off due to accidental contact or other reasons during the placement process.

[0021] An electric push rod 17 is installed on the top of the rotary table. One end of the electric push rod 17 is fixedly connected to the top plate 4. By extending the electric push rod 17, the top can fix and limit the sample tube in the placement slot 3.

[0022] A rectangular frame 18 is fixedly connected to the top of the rectangular platform 21. A third drive motor 19 is installed on the top of the rectangular frame 18. A threaded rod 20 is rotatably connected to the rectangular frame 18 and fixedly connected to the output end of the third drive motor 19. A connecting plate 21 is threadedly connected to the threaded rod 20. One end of the connecting plate 21 is fixedly connected to the top of the rectangular shell 5. A constant temperature module is installed on the inner top of the rectangular shell 5. A transparent glass is installed on the side of the rectangular shell 5. By rotating the threaded rod 20, the sample tube is placed inside the rectangular shell 5 during stability testing. By activating the constant temperature module, the inside of the rectangular shell 5 is kept at a constant temperature, which facilitates the testing of the stability of the suspension under constant temperature conditions. The transparent glass allows external light to illuminate the inside of the rectangular shell 5. It should be noted that an optical scanning head and a light sensor are mounted on the rectangular shell 5. The combination of the two facilitates optical scanning of the suspension in the sample tube, making detection more convenient.

[0023] The swaying mechanism also includes a first drive motor 7 installed at the bottom of the rectangular platform 21. The specific models and specifications of the first drive motor 7, the second drive motor 14 and the third drive motor 19 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0024] The working principle of this utility model: The sample tubes are placed into the placement slot 3 in sequence. The spring and trapezoidal block 16 initially fix the sample tubes. Then, the electric push rod 17 shortens, allowing the top to drop and further fix the sample tubes. Next, the third drive motor 19 drives the threaded rod 20 to rotate, the threaded rod 20 drives the connecting plate 21 to descend, the connecting plate 21 drives the rectangular shell 5 to descend, so that the sample tube is in a relatively sealed environment, and the constant temperature module is lifted to keep the rectangular shell 5 at a constant temperature. Subsequently, the second drive motor 14 drives the second rotating rod 15 to rotate, the second rotating rod 15 drives the rotating table to rotate, and the rotating table drives several sample tubes to rotate at a constant speed. At the same time, the first drive motor 7 drives the first rotating rod 8 to rotate, the first rotating rod 8 drives the rotating plate 9 to rotate, the rotating plate 9 drives the connecting column 10 and the limiting block 11 to rotate, the connecting column 10 drives the connecting ring 12 to move, the connecting ring 12 drives the sliding block 6 to move through the sliding block 6, the sliding block 6 moves back and forth along the limiting frame 13, thereby driving the rotating table to swing back and forth.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
