Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing equipment technology, specifically to an oscillation device for testing liquid pharmaceuticals. Background Technology

[0002] A search revealed Chinese patent publication number CN221999629U, which discloses a vibrating device for detecting liquid drugs. This device includes a base plate with two support plates fixedly mounted on its upper surface. A servo motor is fixedly mounted on the outer side of one of the support plates, and a transverse plate is positioned between the two support plates. This invention places a test tube containing the drug solution into a sleeve, with the sleeve and cap threaded together. A sealing plug is tightly fitted against the inner edge of the test tube to seal the drug solution inside. The servo motor and vibrating motor... When activated, the device can continuously oscillate the liquid inside the test tube. However, the vibration is transmitted to the test tube through a horizontal plate, connecting column, and fixed plate. During the transmission process, some energy is lost. This intermittent oscillation method makes it difficult to control the amplitude and frequency of the liquid oscillation. The mixed liquid may be prone to uneven flow field due to insufficient oscillation amplitude or frequency, especially for high-viscosity liquids or samples containing particles (such as suspensions, emulsions, syrups, etc.), which are prone to local incomplete mixing. Therefore, we propose an oscillation device for liquid drug detection. Utility Model Content

[0017] A wobbling component 4 is provided on the rotating rod 34. The wobbling component 4 includes a first rotating wheel 41, a second rotating wheel 42, and a connecting rod 43. A rectangular hole 44 is provided through the first rotating wheel 41. The rectangular hole 44 is fitted into the adjusting groove 45. Two adjusting grooves 45 are symmetrically arranged. A rotating shaft 46 is fixedly connected to each of the two adjusting grooves 45. The rotating shaft 46 is rotatably connected to the rectangular hole 44. One end of the connecting rod 43 is rotatably connected to the first rotating wheel 41, and the other end of the connecting rod 43 is rotatably connected to the second rotating wheel 42.

[0018] The second rotating wheel 42 has a through hole 47, which is slidably connected to the surface of the rotating rod 34. A keyway 48 is provided in the hole 47. There are two keyways 48 symmetrically arranged. A spline 49 is slidably connected in each of the two keyways 48. The spline 49 is fixedly connected to the rotating rod 34.

[0019] The first rotating wheel 41 has a first annular groove 411, and the second rotating wheel 42 has a second annular groove 421. Both circular plates 36 are slidably connected in the second annular groove 421. A ball 412 is rotatably connected in the first annular groove 411. A push rod 413 is fixedly connected to the ball 412. One end of the push rod 413 is fixedly connected to the bottom of the placement plate 2.

[0020] The input end of the motor 35 is connected to an external power source. The cross-sectional length of the rectangular hole 44 is greater than the diameter of the rotating rod 34, which facilitates the adjustment of the tilt of the first rotating wheel 41. The rotation of the motor 35 drives the rotating rod 34 and the first rotating wheel 41 to rotate, thereby pushing the ball 412 and the push rod 413 to drive the test tube in the placement tray 2 to oscillate. The oscillation frequency is controlled by controlling the speed of the motor 35.

The limit block 56 is fixedly connected to the slide rod 53. There are two limit grooves 55 symmetrically arranged. A spring 57 is sleeved on the slide rod 53. The spring 57 is located between the push plate 51 and the test tube groove 6.

[0023] Spring 57 is a compression spring. Spring 57 pushes push plate 51 and silicone pad 52 to clamp test tubes in test tube slot 6. Slide rod 53 serves to guide and stabilize push plate 51. Limiting groove 55 and limiting block 56 prevent slide rod 53 from disengaging from rod groove 54.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] The working principle of this utility model is as follows: When a test tube is placed in the test tube slot 6, the spring 57 pushes the push plate 51 and the silicone pad 52 to clamp the test tube. When the knob 37 and the threaded rod 33 are rotated, the circular plate 36 drives the second rotating wheel 42 to move along the spline 49 on the surface of the rotating rod 34. The second rotating wheel 42 pushes the connecting rod 43 to drive the first rotating wheel 41 to rotate around the rotating shaft 46 in the adjusting groove 45 to adjust the inclination of the first rotating wheel 41. When the power of the motor 35 is turned on, the motor 35 rotates and drives the rotating rod 34 to rotate, thereby driving the first rotating wheel 41, the second rotating wheel 42 and the connecting rod 43 to rotate. The ball 412 rotates in the first annular groove 411. The first annular groove 411 pushes the ball 412 to move back and forth along the rotating rod 34. The ball 412 drives the placement plate 2 to slide back and forth on the first support plate 31 and the second support plate 32 through the push rod 413, thereby causing the test tube and the medicine in the test tube slot 6 to be vibrated and mixed evenly.
