Description

Technical Field

[0001] This utility model relates to the field of sample processing equipment technology, specifically a mixing device for sample processing. Background Technology

[0002] In scientific experiments, medical testing, chemical analysis and other fields, sample homogenization is a crucial step. The homogenization of the sample directly affects the accuracy and reliability of subsequent experimental results. Traditional sample homogenization methods often rely on manual shaking or the use of simple stirrers. These methods are not only inefficient, but also make it difficult to guarantee the homogenization of the sample.

[0003] In the existing technology, most mixing devices are only suitable for sample tubes of a specific size and lack versatility; some other devices can hold test tubes of different sizes, but they are prone to liquid leakage due to test tube shaking during the mixing process, which affects the experimental environment. Some mixing devices also have shortcomings in mixing effect. Due to design defects in the mixing mechanism, the sample cannot be fully stirred during the mixing process, which affects the experimental results. Therefore, we propose a mixing device for sample processing. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for sample processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mixing device for sample processing includes a mounting frame, a mounting plate at the top of the mounting frame, two upper and lower sliding grooves on the mounting plate, a slider slidably disposed in the sliding grooves, a fixing plate on the side wall of the mounting plate, a first connecting plate on the fixing plate via a rotating shaft, a second connecting plate on the first connecting plate via a rotating shaft, a third connecting plate on the rear outer wall of the slider via a rotating shaft, the third connecting plate being connected to the mounting plate via a mounting shaft, the third connecting plate being connected to the second connecting plate via a fixing shaft, and a clamping mechanism on the front outer wall of the slider via a limiting shaft.

[0007] As a further embodiment of this utility model: the clamping mechanism has a cavity inside, and a plurality of telescopic rods are evenly arranged on the inner wall of the cavity. A clamping plate is provided at the end of the telescopic arm of the telescopic rod, and a rubber pad is provided on the inner wall of the clamping plate. A first spring is sleeved on the outer side of the telescopic rod.

[0008] As a further improvement of this utility model: the clamping mechanism is also provided with an installation cavity, a slide rod is provided inside the installation cavity, a lifting plate is slidably mounted on the slide rod, and a sealing gasket is provided on the lower wall of the lifting plate.

[0009] As a further embodiment of this utility model: one end of the first spring is connected to the clamping plate, and the other end of the first spring is connected to the inner wall of the cavity.

[0010] As a further improvement of this utility model: a second spring is sleeved on the outer side of the slide rod, one end of the second spring is connected to the inner wall of the mounting cavity, and the other end of the second spring is connected to the lifting plate.

[0011] As a further improvement of this utility model: a motor is also provided on the fixed plate, and the power output shaft of the motor is connected to the rotating shaft of the first connecting plate through a coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The first connecting plate is rotated by the motor, and the slider moves back and forth in the groove through the linkage of the second and third connecting plates. This causes the clamping mechanism to shake the sample tube, which can effectively promote the mixing of liquid in the tube and improve the mixing effect. At the same time, the clamping mechanism, under the action of the clamping plate, the telescopic rod and the first spring, makes the device applicable to sample tubes of different sizes, thus enhancing the applicability of the device.

[0014] 2. The lifting plate and sealing gasket on the clamping mechanism can form a tight seal at the opening of the test tube, preventing liquid from splashing or leaking during the mixing process. This not only improves the cleanliness of the experimental environment but also avoids experimental errors caused by liquid leakage, further enhancing the accuracy and reliability of the experiment.

[0022] Example

[0023] Please see Figures 1-5 In this embodiment of the present invention, a mixing device for sample processing includes a mounting frame 1, a mounting plate 2 at the top of the mounting frame 1, two upper and lower sliding grooves on the mounting plate 2, a slider 7 slidably disposed in the sliding grooves, a fixing plate 3 on the side wall of the mounting plate 2, a first connecting plate 4 on the fixing plate 3 via a rotating shaft, a second connecting plate 5 on the first connecting plate 4 via a rotating shaft, and a third connecting plate 10 on the rear outer wall of the slider 7 via a rotating shaft. The third connecting plate 10 is connected to the mounting plate 2 via a mounting shaft 8 and to the second connecting plate 5 via a fixing shaft 9. At this point, the first connecting plate 4, the second connecting plate 5, and the third connecting plate 10 are connected together. The upper and lower sliders 7 can move left and right, and the two sliders 7 can also move towards each other. A clamping mechanism 11 is set on the outer wall of the front side of the slider 7 through a limiting shaft. At this time, under the action of the two sliders 7 that can move left and right, the clamping mechanism 11 is driven to swing left and right in the horizontal direction, so as to better shake the sample. To a certain extent, the shaking quality of the sample by the device is guaranteed. A motor 6 is also set on the fixed plate 3. The power output shaft of the motor 6 is connected to the rotation shaft of the first connecting plate 4 through a coupling. At this time, the motor 6 can drive the first connecting plate 4 to move, so as to better drive the clamping mechanism 11 to swing, thereby shaking the sample.

[0024] The clamping mechanism 11 has an internal cavity with several telescopic rods 12 evenly arranged on the inner wall of the cavity. A clamping plate 14 is provided at the end of the telescopic arm of the telescopic rod 12. Under the action of the clamping plate 14, the sample tube can be clamped and fixed. It can also meet the clamping and fixing of sample tubes of different sizes, which improves the applicability of the device to a certain extent. A first spring 13 is sleeved on the outside of the telescopic rod 12. One end of the first spring 13 is connected to the clamping plate 14, and the other end of the first spring 13 is connected to the inner wall of the cavity. Under the action of the first spring 13, the fixing quality of the clamping plate 14 for the sample tube is guaranteed, thereby ensuring the subsequent shaking quality. A rubber pad is provided on the inner wall of the clamping plate 14. Under the action of the rubber pad, the damage to the test tube caused by the clamping plate 14 is reduced.

[0025] The clamping mechanism 11 is also provided with an installation cavity, inside which is a slide rod 15. A lifting plate 16 is slidably mounted on the slide rod 15. A sealing gasket 18 is provided on the lower wall of the lifting plate 16. Under the action of the sealing gasket 18, the opening of the test tube can be better sealed, reducing the leakage of liquid inside the test tube during shaking, thereby ensuring the efficiency of the device. A second spring 17 is sleeved on the outside of the slide rod 15. One end of the second spring 17 is connected to the inner wall of the installation cavity, and the other end of the second spring 17 is connected to the lifting plate 16. Under the action of the second spring 17, the sealing quality of the sealing gasket 18 for the sample test tube is ensured, thereby ensuring the efficiency of the device.

[0026] In actual use, the sample tube to be shaken is placed in the clamping mechanism 11. Several telescopic rods 12 are provided in the cavity inside the clamping mechanism 11. These telescopic rods 12 automatically adjust the length of their telescopic arms according to the size of the sample tube, so that the clamping plate 14 can tightly fit and fix the tube. The first spring 13 on the outside of the telescopic rod 12 ensures that the clamping plate 14 applies stable pressure to the tube, which enhances the reliability of the fixation and the stability during the shaking process. The motor 6 is then started. The power of motor 6 is transmitted to the rotating shaft of the first connecting plate 4 through a coupling, causing the first connecting plate 4 to rotate. Since the first connecting plate 4, the second connecting plate 5, and the third connecting plate 10 are interconnected by rotating shafts, and the third connecting plate 10 is also connected to the mounting plate 2 through the mounting shaft 8 and to the second connecting plate 5 through the fixed shaft 9, this linkage mechanism transforms the rotational motion of motor 6 into the reciprocating movement of two sliders 7 in the groove, achieving the effect of the two sliders 7 moving towards each other, thus enhancing the uniformity of mixing. As the sliders 7 move left and right, the clamping mechanism 11 on its front outer wall also sways left and right in the horizontal direction. This swaying motion effectively agitates the liquid in the sample tube, promoting uniform mixing and improving the shaking effect. The lifting plate 16 on the clamping mechanism 11 and the sealing gasket 18 below it can automatically adjust their positions according to the height of the test tube under the action of the sliding rod 15 and the second spring 17, ensuring that the sealing gasket 18 tightly fits the opening of the test tube. This design not only reduces the risk of liquid leakage during shaking but also improves the efficiency and safety of the device.
