Description

Technical Field

[0001] This utility model relates to an oscillation device, specifically a glass centrifuge tube oscillation device for food testing, belonging to the technical field of food testing equipment. Background Technology

[0002] In many areas of food testing, some tests (such as plasticizer detection) have strict requirements for sample processing conditions, necessitating the use of containers made of specific materials, such as glass centrifuge tubes, to ensure the reliability and accuracy of the analytical results. Traditional sample pretreatment typically involves shaking the solution to ensure thorough contact between the reagents and the sample. However, in practice, due to the large number of samples being tested, operators often need to spend a significant amount of time and effort manually shaking the solution. This is not only labor-intensive and inefficient, but also prone to incomplete mixing or poor repeatability due to human error.

[0003] In the prior art, such as the centrifuge tube shaking device disclosed in CN213376303U, a base and a shaking plate are included. The shaking plate is disposed above the base, and the base is equipped with a power switch and a vibration speed control knob. A vibration motor for driving the shaking plate is installed inside the base. A test tube rack is detachably installed on the top of the shaking plate, and centrifuge tube mounting holes are provided on the test tube rack. Currently, most shaking devices on the market are designed for plastic centrifuge tubes or separatory funnels, and the number of test tubes shaken at one time is limited. This not only fails to meet the pretreatment needs of large batches of glass centrifuge tubes, but also their adaptability is often not fully suitable for the ground glass stoppers of glass centrifuge tubes. In practical use, these devices may experience leakage due to incomplete sealing of the tube openings, and may not be able to shake a large number of glass centrifuge tubes efficiently at the same time. In addition, existing devices mostly use horizontal vibration, which not only makes it difficult to achieve the more effective vertical shaking effect for specific components (such as the detection of plasticizers), but also proves inadequate for handling high viscosity or complex matrices. These shortcomings make it difficult for existing equipment to meet the requirements of rapid, efficient, and high-volume oscillation in food testing. Utility Model Content

[0004] The purpose of this invention is to provide a glass centrifuge tube oscillation device for food testing, which is suitable for efficient homogenization and pretreatment of batch samples in food testing, biochemical analysis, and other fields. This device can be widely used in various laboratories and testing institutions, helping to improve the efficiency of sample pretreatment and the stability of test results.

[0005] The present invention achieves the above objectives through the following technical solution: a glass centrifuge tube oscillation device for food testing, comprising an oscillation body and a centrifuge tube limiting component, wherein the centrifuge tube limiting component is connected above the oscillation body, and the oscillation body consists of a shell and an oscillation motor fixedly connected inside the shell;

[0006] The centrifuge tube limiting assembly includes an oscillating rod, a bottom limiting plate, and a top limiting plate. The bottom and top limiting plates are coaxially fixedly connected to the rod body of the oscillating rod. The top limiting plate is arranged parallel above the bottom limiting plate. The bottom end of the oscillating rod is coaxially aligned with the rotating shaft of the oscillating motor of the oscillating body.

[0007] As a further improvement of this utility model, a power switch, a timing knob, and an intensity knob are provided on the outer shell of the oscillating body.

[0008] As a further improvement of this utility model, a display screen is also provided on the outer shell of the oscillating body, and the display screen is installed between the timing knob and the intensity knob.

[0009] As a further improvement of this utility model: a support base is provided at the four bottom corners of the oscillating body. The support base includes a support column and a shock-absorbing suction cup. The upper end of the support column is fixedly connected to the four bottom corners of the oscillating body, and the shock-absorbing suction cup is fixedly connected to the lower end of the support column.

[0010] As a further embodiment of this utility model: the oscillating rod includes a fixed base, a sealing ring, a drive shaft, a shock-absorbing pad, a protective shell, an adjustment groove, and a protective cover; the fixed base is fixedly connected to the outer shell of the oscillating body, the drive shaft is coaxially fixedly connected to the rotating shaft of the oscillating motor of the oscillating body, the sealing ring is placed at the connection between the fixed base and the outer shell of the oscillating body, the shock-absorbing pad is sleeved between the drive shaft and the fixed base, the protective shell is sleeved on the outside of the drive shaft, the protective cover is installed on the top of the protective shell, and the adjustment groove is set on both sides between the protective cover and the protective shell.

[0011] As a further improvement of this utility model: the bottom limiting plate is fixedly connected between the shock-absorbing pad and the protective shell, and the bottom limiting plate is provided with multiple test tube limiting holes.

[0012] As a further embodiment of this utility model: the top limiting plate is slidably connected between the adjusting groove and the protective cover, and the surface of the top limiting plate is equipped with a bottle mouth groove, a pressing column, a pressing screw and a pressing plate, and a fixing hole plate and fixing screws are installed below the top limiting plate.

[0013] The beneficial effects of this invention are as follows: By optimizing the test tube clamping structure, this invention ensures that the glass centrifuge tubes remain stable and reliable during high-speed shaking, preventing the glass stopper from loosening or the solution from leaking. Simultaneously, by rationally setting the capacity and frequency control of the shaking mechanism, it can efficiently and uniformly shake and mix a large number of glass centrifuge tubes at once, thus avoiding the time-consuming and labor-intensive nature of manual shaking, poor repeatability, and the limited number of tubes that can be shaken at one time by traditional shaking devices. Furthermore, the use of vertical oscillation makes it more suitable for certain food testing applications. Thanks to the innovative design of this invention, the pretreatment stage in food testing is significantly improved, and the stability and consistency of test results are effectively enhanced, providing a more practical shaking device for relevant laboratories and testing institutions.

[0031] The oscillating rod 3 includes a fixed base 31, a sealing ring 32, a drive shaft 33, a shock-absorbing pad 34, a protective shell 35, an adjusting groove 36, and a protective cover 37. The fixed base 31 is fixedly connected to the outer shell of the oscillating body 1, the drive shaft 33 is coaxially fixedly connected to the rotating shaft of the oscillating motor of the oscillating body 1, the sealing ring 32 is placed at the connection between the fixed base 31 and the outer shell of the oscillating body 1, the shock-absorbing pad 34 is sleeved between the drive shaft 33 and the fixed base 31, the protective shell 35 is sleeved on the outside of the drive shaft 33, and the protective cover 37 is installed on the outer shell.
