Description

Technical Field

[0001] The utility model relates to the technical field of laboratory appliances, in particular to a centrifuge tube with a grinding function. Background Art

[0002] Centrifugal separation is a frequently used operation in industrial production and laboratory analysis. The centrifuge tubes used in laboratory analysis are mostly standard styles, mainly cylindrical tubes and centrifuge tube caps that match the tubes. When experimenters are doing DNA, RNA or protein extraction experiments, they need to grind the samples in advance. The traditional practice is to pour the samples into a mortar for grinding, and then divide them into centrifuge tubes for centrifugal extraction experiments.

[0003] Existing centrifuge tubes do not have a grinding function, so when grinding samples, the same mortar must be used to grind multiple samples, which is prone to cross infection. Experimenters need to frequently change mortars. Alternatively, centrifuge tubes have a grinding function, but the samples inside need to be ground manually, which is time-consuming and laborious, and it is easy for the medicine to be incompletely ground, affecting the experimental effect of the sample. Therefore, a centrifuge tube with a grinding function is proposed to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the embodiment, Figure 1-4 A centrifuge tube with a grinding function is provided. The utility model comprises a support frame 1 and a centrifuge tube body 2. The outer side of the centrifuge tube body 2 is threadedly connected with a tube cover 3. The inside of the tube cover 3 is slidably connected with a grinding rod 4 extending into the inside of the centrifuge tube body 2. The bottom of the grinding rod 4 is fixedly connected with a grinding piece 5. The top of the grinding rod 4 is fixedly connected with a connecting piece 6 located on the upper side of the tube cover 3. The internal thread of the connecting piece 6 is connected with a connecting column 7. The left side of the support frame 1 is fixedly connected with a support plate 8. The inside of the support plate 8 is slidably connected with the connecting column 7. The top of the connecting column 7 is fixedly connected with a sliding piece 9. The left side of the support frame 1 is fixedly connected with a cylinder 11. The output shaft of the cylinder 11 is fixedly connected with a sliding table 12 in contact with the sliding piece 9.

[0026] Place the sample inside the centrifuge tube body 2, fix the centrifuge tube body 2 on the inner bottom wall of the support frame 1, connect the connecting column 7 with the connecting piece 6, start the cylinder 11, and the cylinder 11 drives the sliding table 12 to slide. Due to the tilting effect of the sliding table 12, the sliding table 12 drives the sliding piece 9 to rise or fall, so that the sliding piece 9 drives the connecting column 7 to rise or fall, the connecting column 7 drives the connecting piece 6 to rise or fall, the connecting piece 6 drives the grinding rod 4 to rise or fall, and the grinding rod 4 drives the grinding piece 5 to rise or fall on the inner bottom wall of the centrifuge tube body 2, thereby impacting the sample to crush the sample.

[0027] Specifically, refer to Figure 3 A slide rail 13 is fixedly connected to the left side of the support frame 1, and the slide rail 13 is slidably connected to the slide platform 12.

[0028] In this embodiment, the cylinder 11 drives the sliding table 12 to slide inside the slide rail 13, making the sliding of the cylinder 11 more stable, thereby making the rise and fall of the sliding member 9 more stable, and further making the lower grinding rod 4 drive the grinding member 5 to rise or fall more stably.

[0029] Specifically, refer to Figure 2 The interior of the sliding member 9 is rotatably connected with a rotating wheel 14 , and the rotating wheel 14 is slidably connected to the bottom of the sliding platform 12 .

[0030] In this embodiment, when the sliding platform 12 slides left and right, the sliding platform 12 drives the rotating wheel 14 to rotate, reducing the friction between the sliding platform 12 and the sliding member 9, so that the rotating wheel 14 drives the sliding member 9 to rise or fall.

[0031] Specifically, refer to Figure 2 and Figure 3 The sliding platform 12 is trapezoidal, the grinding piece 5 is spherical, and the bottom of the sliding piece 9 is fixedly connected with a spring 10.

[0032] In this embodiment, when the sliding platform 12 slides to the left, the sliding platform 12 drives the rotating wheel 14 to descend, and the rotating wheel 14 drives the sliding member 9 to descend, the spring 10 is compressed, and the elastic potential energy of the spring 10 increases. When the sliding platform 12 slides to the right, the pressure of the sliding platform 12 on the rotating wheel 14 is reduced, the elastic potential energy of the spring 10 is released, and the spring 10 recovers, driving the sliding member 9 to move upward, and the sliding member 9 drives the rotating wheel 14 to move upward, so that the rotating wheel 14 always slides against the bottom of the sliding platform 12.

[0033] Specifically, refer to Figure 1 The inner bottom wall of the support frame 1 is rotatably connected with a rotating ring 15, the outer side of the rotating ring 15 is fixedly connected with an electric push rod 16, the output shaft of the electric push rod 16 is fixedly connected with a clamping plate 17 located inside the rotating ring 15, and the clamping plate 17 is in conflict with the outer side of the centrifuge tube body 2.

[0034] In this embodiment, the centrifuge tube body 2 is placed inside the two clamping plates 17, and the electric push rod 16 is started. The electric push rod 16 drives the clamping plates 17 to approach the outside of the centrifuge tube body 2, so that the clamping plates 17 fix the centrifuge tube body 2.

[0035] Specifically, refer to Figure 4 A worm gear 18 is arranged on the outer side of the rotating ring 15 , a motor 19 is fixedly connected to the inner bottom wall of the support frame 1 , a worm 20 is fixedly connected to the output shaft of the motor 19 , and the worm 20 is meshed with the worm gear 18 .

[0036] In this embodiment, the motor 19 is started, the motor 19 drives the worm 20 to rotate, the worm 20 drives the worm wheel 18 to rotate, the worm wheel 18 drives the rotating ring 15 to rotate, the rotating ring 15 drives the electric push rod 16 to rotate, the electric push rod 16 drives the clamping plate 17 to rotate, and the clamping plate 17 drives the centrifuge tube body 2 to rotate, so that the centrifuge tube body 2 rotates while the grinding member 5 grinds the sample inside the centrifuge tube body 2.

[0037] Working principle:

[0038] First, put the medicine into the centrifuge tube body 2, cover the tube cover 3, put the centrifuge tube body 2 into the rotating ring 15 for clamping, connect the connecting column 7 and the connecting piece 6, and drive the sliding table 12 to slide due to the tilting effect of the sliding table 12. Therefore, the sliding table 12 drives the sliding piece 9 to rise or fall, so that the sliding piece 9 drives the connecting column 7 to rise or fall, the connecting column 7 drives the connecting piece 6 to rise or fall, the connecting piece 6 drives the grinding rod 4 to rise or fall, and the grinding rod 4 drives the grinding piece 5 to rise or fall on the inner bottom wall of the centrifuge tube body 2, thereby impacting the sample;

[0039] Then: at the same time, the motor 19 drives the worm 20 to rotate, the worm 20 drives the worm wheel 18 to rotate, the worm wheel 18 drives the rotating ring 15 to rotate, the rotating ring 15 drives the electric push rod 16 to rotate, the electric push rod 16 drives the clamping plate 17 to rotate, and the clamping plate 17 drives the centrifuge tube body 2 to rotate, so that the centrifuge tube body 2 rotates while the grinding piece 5 grinds the sample inside the centrifuge tube body 2, so that the sample is crushed more evenly and is more conducive to the experiment.
