[0038] like Figure 1-4 As shown, the utility model provides a liquid rotating and shaking device, including a frame 100, a positioning seat 200, a first driving assembly, a sealing member 300 and a second driving assembly.

[0039] The positioning seat 200 is arranged on the frame 100, and the positioning seat 200 is rotatably connected to the frame 100. The positioning seat 200 has a positioning groove adapted to the sampling tube 400. Preferably, a clamping assembly is arranged in the positioning groove to achieve the purpose of clamping and positioning the sampling tubes 400 with different outer diameters.

[0040] The first driving assembly is disposed on the frame 100, and the first driving assembly is used to drive the positioning seat 200 to rotate. The sealing member 300 is disposed above the positioning seat 200, and the sealing member 300 has a first position and a second position. When the sealing member 300 is in the first position, the sealing member 300 is separated from the sampling tube 400, and when the sealing member 300 is in the second position, the sealing member 300 seals the sampling tube 400.

[0041] The second driving assembly is disposed on the frame 100 , and is used to drive the sealing member 300 to reciprocate between the first position and the second position.

[0042] When in use, the sampling tube 400 to be shaken is placed in the positioning groove, and then the second drive component is started, and the second drive component drives the seal 300 to descend from the first position to the second position, so as to achieve the purpose of sealing the tube mouth of the sampling tube 400. Then, the first drive component is started, and the first drive component drives the positioning seat 200 to rotate, thereby driving the sampling tube 400 placed on the positioning seat 200 to rotate, thereby achieving the purpose of fully mixing the acetone and / or acid bottles in the sampling tube 400 with the water to be tested.

[0043] Preferably, when the first driving assembly drives the positioning seat 200 to rotate the sampling tube 400, the sampling tube 400 will rotate with the sealing member 300, thereby preventing the sampling tube 400 and the sealing member 300 from wearing each other due to relative movement.

[0044] The liquid rotating and shaking device provided by the utility model can automatically seal and shake the sampling tube 400, has a simple structure, a reasonable design, is easy to operate, and improves efficiency.

[0045] In one embodiment, the first driving assembly includes a motor 510 , a rotating disk 520 , a first gear 530 , and a second gear 540 .

[0046] The motor 510 is fixedly arranged in the frame 100. The turntable 520 is rotatably arranged on the frame 100, and the turntable 520 is drivingly connected with the power output shaft of the motor 510. In the present embodiment, the turntable 520 is coaxially sleeved on the power output shaft of the motor 510 and is fixedly connected with the power output shaft of the motor 510. The positioning seat 200 is rotatably arranged on the turntable 520 and can rotate with the turntable 520. Specifically, the positioning seat 200 is arranged on the turntable 520 and is rotatably connected to the turntable 520, and the positioning seat 200 can also rotate with the turntable 520, that is, when the turntable 520 rotates, the positioning seat 200 can rotate with the turntable 520, that is, the positioning seat 200 can both rotate around its own rotation center line and revolve around the rotation center line of the turntable 520.

[0047] The first gear 530 is arranged below the rotating disk 520, and the first gear 530 is fixedly connected to the frame 100. In the present embodiment, the first gear 530 is an inner gear ring. The second gear 540 is rotatably arranged on the rotating disk 520 and can rotate with the rotating disk 520. Specifically, the second gear 540 is arranged below the rotating disk 520 and is rotatably connected with the rotating disk 520, and the second gear 540 can also rotate with the rotating disk 520, that is, when the rotating disk 520 rotates, the second gear 540 can rotate with the rotating disk 520, that is, the second gear 540 can not only rotate around its own rotation center line, but also revolve around the rotation center line of the rotating disk 520. The second gear 540 is transmission-connected to the positioning seat 200, and the second gear 540 is meshed with the first gear 530.

[0048] When in use, the motor 510 drives the turntable 520 to rotate, and the turntable 520 orbits with the second gear 540 and the positioning seat 200, so that the sampling tube 400 orbits with the turntable 520. In this process, under the action of the first gear 530, the first gear 530 drives the second gear 540 to rotate around its own rotation center line, and the second gear 540 drives the positioning seat 200 to rotate around its own rotation center line, thereby achieving the purpose of driving the sampling tube 400 to rotate.

[0049] The first driving assembly provided in this embodiment can not only drive the sampling tube 400 to rotate, but also drive the sampling tube 400 to revolve, thereby achieving the purpose of improving the shaking effect.

[0050] Preferably, a plurality of positioning seats 200 are provided, the number of second gears 540 is equal to and corresponds to the number of positioning seats 200, and all second gears 540 are meshed with the first gear 530, so as to achieve the purpose of shaking multiple sampling tubes 400 at the same time, thereby achieving the purpose of improving the shaking efficiency.

[0051] Preferably, the plurality of positioning seats 200 are evenly arranged around the axis of the turntable 520 .

[0052] In one embodiment, the second driving assembly includes a lifting base 610 , a carrying plate 620 and a driving structure.

[0053] The lifting seat 610 is arranged above the turntable 520, and the lifting seat 610 is slidably connected to the frame 100. The lifting seat 610 can make a reciprocating linear motion between the third position and the fourth position in the longitudinal direction. The carrying plate 620 is arranged below the lifting seat 610 and is rotatably connected to the lifting seat 610. The carrying plate 620 can move with the lifting seat 610, and the axis of the carrying plate 620 coincides with the axis of the turntable 520. That is, the carrying plate 620 can not only make a lifting motion together with the lifting seat 610, but also rotate around its own rotation center line.

[0054] The driving structure is disposed on the frame 100, and the driving structure is used to drive the lifting seat 610 to perform reciprocating linear motion between the third position and the fourth position. In one embodiment, the driving structure includes an electric push rod 630, the electric push rod 630 is fixedly connected to the frame 100, and the power output shaft of the electric push rod 630 is fixedly connected to the lifting seat 610.

[0055] The number of the sealing members 300 is equal to and corresponds to the number of the positioning seats 200. The sealing members 300 are arranged on the carrier plate 620 and are rotatably connected to the carrier plate 620. That is, the sealing members 300 can rotate along with the rotation of the carrier plate 620, so that the sealing members 300 can revolve around the rotation center line of the carrier plate 620. At the same time, since the sealing members 300 are rotatably connected to the carrier plate 620, the sealing members 300 can also rotate around their own rotation center line. When the lifting seat 610 is in the third position, the sealing members 300 are in the first position, and when the lifting seat 610 is in the fourth position, the sealing members 300 are in the second position.

[0056] When in use, the driving structure drives the lifting seat 610 to descend from the third position to the fourth position, thereby achieving the purpose of driving the sealing member 300 from the first position to the second position, and further achieving the purpose of sealing the sampling tube 400.

[0057] Since the seal 300 is rotatably connected to the carrier plate 620, and the carrier plate 620 is rotatably connected to the lifting seat 610, and the rotation center line of the carrier plate 620 coincides with the rotation center line of the turntable 520, when the motor 510 drives the turntable 520 to rotate, the sampling tube 400 will rotate around its own rotation center line while revolving with the turntable 520, and the sampling tube 400 will rotate around its own rotation center line with the seal 300, and at the same time, the sampling tube 400 can also rotate around its own rotation center line with the carrier plate 620 through the seal 300, thereby achieving the purpose of driving the seal 300 to revolve around the rotation center line of the carrier plate 620.

[0058] The second driving assembly provided in this embodiment has a simple structure and a reasonable design, and enables the sealing member 300 to not only rotate along with the sampling tube 400 but also revolve along with the sampling tube 400 .

[0059] In one embodiment, a driving rod 521 is provided on the top of the turntable 520, and the cross-section of the driving rod 521 is prismatic or non-circular. The bottom end of the driving rod 521 is fixedly connected to the turntable 520, and the top end is rotatably connected to the frame 100. The supporting plate 620 is sleeved on the driving rod 521 and is slidably connected to the driving rod 521.

[0060] When in use, since the cross section of the driving rod 521 is prismatic or non-circular, under the action of the driving rod 521, the driving rod 521 will prevent the rotating disk 520 and the carrying disk 620 from rotating relative to each other, thereby achieving the purpose of always keeping the positioning seat 200 on the rotating disk 520 and the sealing member 300 on the carrying disk 620 corresponding to each other, thereby achieving the purpose of positioning the positioning seat 200 and the sealing member 300. At the same time, when the motor 510 drives the rotating disk 520 to rotate, the rotating disk 520 drives the carrying disk 620 to rotate together through the driving rod 521, rather than driving the carrying disk 620 to rotate through the sampling tube 400, thereby achieving the purpose of reducing the risk of damaging the sampling tube 400.

[0061] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
