Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sample mixing technology, and in particular relates to a high-efficiency and rapid sample mixing device for centrifuge tubes. Background Technology
[0002] Centrifuge tubes are a common container in laboratories, used for sample preparation, sample mixing, and other experiments. In sample mixing, the common method involves placing the centrifuge tube in a turntable and mixing by varying the rotation speed over time. However, since the mixing motion is solely driven by the turntable, the turntable speed needs constant adjustment to ensure thorough mixing, making the operation cumbersome. Improper operation can easily lead to insufficient mixing and low efficiency. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a high-efficiency and fast sample mixing device for centrifuge tubes. By combining the movement of the centrifuge tube following the rotation of the turntable and the spin of the centrifuge tube, the mixing degree and mixing efficiency are improved.
[0004] Technical solution: To achieve the above objectives, this utility model provides a high-efficiency and rapid centrifuge tube sample mixing device, which includes a turntable with tube seats on the disc surface and a tube pressing frame that is lifted and set on the turntable. The centrifuge tubes sitting in the tube seats are positioned by pressing down on the tube pressing frame.
[0005] The tube seat is rotatably mounted on the turntable, and a spin drive unit corresponding to the tube seat is provided in the base of the turntable. A rotating tube pressing head is rotatably mounted on the arm of the tube pressing frame that presses down on the centrifuge tube. While the centrifuge tube rotates with the turntable, the spin drive unit drives the tube seat to make the centrifuge tube spin.
[0006] Furthermore, several of the aforementioned tube seats are arranged in a circular array on the turntable.
[0007] Furthermore, the tube seat includes a seat groove rotatably mounted on a turntable and an elastic liner laid in the seat groove, and the centrifuge tube sitting in the seat groove has its bottom wrapped by the elastic liner's rebound.
[0008] Furthermore, the elastic liner has through holes evenly distributed on it.
[0009] Furthermore, the rotating tube pressing head includes a pressure plate rotatably mounted at the end of the frame arm and an elastic pressure pad laid on the lower surface of the pressure plate. When the pressure plate moves down with the tube pressing frame and touches the centrifuge tube, the pressure plate elastically presses down on the tube cap of the centrifuge tube through the elastic pressure pad.
[0010] Furthermore, the spin drive unit drives each of the tube seats on the connected turntable to drive each centrifuge tube sitting in the corresponding tube seat to spin synchronously.
[0011] Furthermore, it includes a lifting unit corresponding to the tube pressing frame, the lifting unit driving the tube pressing frame to rise and fall.
[0012] Beneficial effects: This utility model improves the existing one-dimensional mixing control of the centrifuge tube by combining the rotation of the centrifuge tube with the spin of the centrifuge tube, thereby transforming it into a two-dimensional mixing control that combines the centrifuge tube with the spin. This increases the degree of mixing motion, generates sufficient mixing energy, and enables the sample solution to be mixed efficiently and uniformly, thus improving the mixing efficiency.

[0015] Figure 3 This is a half-sectional schematic diagram of the tube seat, rotating pressure head, and centrifuge tube. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1 , Figure 2 as well as Figure 3 As shown, a high-efficiency and rapid centrifuge tube sample mixing device includes a turntable 1 with tube holders 2 on its surface and a tube clamping frame 3 that is lifted and lowered on the turntable 1. Centrifuge tubes 5, which sit in the tube holders 2, are positioned by being pressed down by the tube clamping frame 3. The tube holders 2 are rotatably mounted on the turntable 1. A spin drive unit 7 corresponding to the tube holders 2 is provided in the base 6 of the turntable 1. A rotating tube clamping head 8 is rotatably mounted on the arm 30 of the tube clamping frame 3 that presses down on the centrifuge tubes 5. While the centrifuge tubes 5 rotate with the turntable 1, the spin drive unit 7 drives the tube holders 2 to cause the centrifuge tubes 5 to spin. This invention improves the existing "one-dimensional mixing control" of the turntable by combining the movement of the centrifuge tubes 5 following the rotation of the turntable 1 with the spin of the centrifuge tubes 5, thereby improving the mixing motion of the turntable into a "two-dimensional mixing control" that combines the turntable and spin. This increases the degree of mixing motion, generates sufficient mixing energy, and efficiently mixes the sample solution uniformly, thus improving the mixing efficiency.
[0018] To achieve homogenization of multi-tube samples and improve efficiency, such as Figure 1 As shown, several of the tube seats 2 are arranged in a circular array on the turntable 1, such as... Figure 2As shown, the spin drive unit 7 drives each of the tube seats 2 on the connected turntable 1 to drive each centrifuge tube 5 sitting in the corresponding tube seat 2 to spin synchronously. The spin drive unit 7 can be a motor-driven gear chain transmission mechanism or a belt drive mechanism. If a motor-driven gear chain transmission mechanism is selected, the gear is installed on the rotating shaft of the tube seat 2. If a motor-driven belt drive mechanism is selected, the pulley is installed on the rotating shaft of the tube seat 2, and the output shaft of the motor is connected to the rotating shaft of one of the tube seats 2.
[0019] like Figure 3 As shown, the tube seat 2 includes a seat groove 21 rotatably mounted on the turntable 1 and an elastic liner 22 laid in the seat groove 21. The centrifuge tube 5, which sits in the seat groove 21, has its bottom wrapped by the elastic liner 22, ensuring the stability of the centrifuge tube 5. Since the movement of the centrifuge tube 5 in this invention includes following the rotation of the turntable 1 and spinning, the degree of movement is relatively large. In order to further improve the stability of the centrifuge tube 5, through holes 20 are evenly distributed on the elastic liner 22. The presence of through holes 20 can increase the friction between the centrifuge tube 5 and the elastic liner 22, reducing the risk of the centrifuge tube 5 sliding or tilting.
[0020] like Figure 1 and Figure 3 As shown, the rotating tube pressing head 8 includes a pressure plate 81 rotatably mounted at the end of the arm 30 and an elastic pressure pad 82 laid on the lower surface of the pressure plate 81. When the pressure plate 81 moves down with the tube pressing frame 3 and touches the centrifuge tube 5, the pressure plate 81 elastically presses down on the tube cap of the centrifuge tube 5 through the elastic pressure pad 82.
[0021] The elastic liner 22 and elastic pad 82 of this utility model can be made of rubber material.
[0022] like Figure 1 As shown, this utility model includes a lifting part 9 corresponding to the pipe pressing frame 3, which drives the pipe pressing frame 3 to move up and down. The lifting part 9 can be electric, such as an electric push rod, or it can be manual, such as a screw that is threaded into the pipe pressing frame 3. The lower end of the screw is connected to the turntable 1 through a bearing seat, and a turning handle is installed on the upper end of the screw.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
