Description

Technical Field

[0001] This utility model belongs to the technical field of water bath pots, specifically relating to a water bath pot shaking lid. Background Technology

[0002] A water bath is an essential component of cell resuscitation processes. In cell resuscitation, cryovials need to be placed in a water bath to thaw. To ensure rapid and uniform warming of the cryovials stored at low temperatures, they need to be shaken within the water bath. However, to avoid contamination and localized temperature differences, operators do not directly hold the cryovials and shake them; instead, they use tools like tweezers to hold and shake them. This method has several drawbacks: firstly, tweezers offer poor stability, requiring operators to maintain focus while shaking the cryovials; secondly, tweezers can only hold one cryovial at a time, resulting in lower cell resuscitation efficiency. Utility Model Content

[0003] This invention provides a shaking lid for a water bath, which solves the technical problems of low cell recovery efficiency and operational difficulty caused by operators using tweezers or similar tools to hold cryopreservation tubes and shake them in a water bath.

[0004] This utility model includes: a cover;

[0005] The first gear assembly includes a drive gear and a first gear shaft connected to the drive gear. The drive gear is located at the center of the inside of the cover, and the first gear shaft extends out of the top surface of the cover.

[0006] A plurality of second gear assemblies are evenly distributed in a ring around the first gear assembly and mesh with the first gear assembly respectively. Each second gear assembly includes a driven gear and a second gear shaft connected to the driven gear, and each second gear shaft extends out of the bottom surface of the cover.

[0007] Several rotating disks, the position and number of which correspond one-to-one with several second gear shafts, and the center of the top surface of each rotating disk is connected to the corresponding second gear shaft;

[0008] Each of the rotating disks has an eccentric rod on its bottom surface, and each of the eccentric rods has a collar at its lower part;

[0009] The crank handle is connected to the first gear shaft.

[0010] This invention only requires the operator to place the cover on the water bath and then directly crank the handle. The handle drives the first gear assembly to rotate, which in turn drives multiple second gear assemblies to rotate, thus causing multiple rotating discs to rotate separately, ultimately driving the eccentric rod and the collar to rotate. The eccentric rod can drive the collar to perform circular motion.

[0011] Furthermore: the cover includes a top plate and a bottom plate, the bottom plate is provided with a plurality of connecting pins, the connecting pins pass through the top plate, and the upper part of the connecting pin is provided with a locking nut. The beneficial effects of this step are: the split-type cover is easier to install and disassemble, facilitates the maintenance of the first gear assembly and the second gear assembly, and also reduces the manufacturing difficulty.

[0012] Furthermore, the bottom surface of the cover is provided with a sealing plate. The beneficial effect of this step is that the sealing plate is compatible with the rim of the water bath and can be completely covered on it, preventing warm water from splashing out when shaken.

[0013] Furthermore: the collar includes an outer ring and an inner ring, wherein the inner ring is axially connected to the outer ring;

[0014] The outer ring is provided with a pin, which is used to connect with the eccentric rod. The beneficial effects of this step are: the inner ring is used to place the cryopreservation tube, and the axial connection between the inner ring and the outer ring allows the inner ring to rotate inside the outer ring. When the cryopreservation tube is placed in the inner ring, the center of gravity of the cryopreservation tube is downward, and the inner ring can generally only sway left and right, thereby increasing the swaying amplitude of the cryopreservation tube and allowing the internal cells and culture medium to be heated more evenly.

[0015] The pin connects to the eccentric rod, allowing the outer ring and eccentric rod to separate when taking out or putting in the cryopreservation tube, making operation convenient.

[0016] Furthermore, the outer ring is also provided with a handle. The beneficial effect of this step is that the handle allows the operator to grip the outer ring, avoiding direct contact between the fingers and the cryopreservation tube.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model places the cryopreservation tube into the collar, and then places the cap on the water bath. The operator can drive the collar to achieve circular motion by turning the handle, which is driven by a series of transmission components. This can replace manual shaking of the cryopreservation tube. First, the collar replaces tweezers and other clamping tools, which is more stable and there is no need to worry about the cryopreservation tube falling into the water bath. Then, several collars can thaw multiple cryopreservation tubes at the same time.

[0019] 2. Operators only need to place the cryopreservation tube into the ring, close the cap, and concentrate on cranking the handle, which simplifies the operation. Attached Figure Description

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0028] Implementation of this application, for example Figure 1 and Figure 2 As shown, this utility model provides a water bath pot shaking lid.

[0029] This application includes: a cover 1;

[0030] The first gear assembly 2 includes a drive gear 21 and a first gear shaft 22 connected to the drive gear 21. The drive gear 21 is located at the center inside the cover 1. The first gear shaft 22 extends out of the top surface of the cover 1 and is axially connected to the cover 1 at both ends.

[0031] Several second gear assemblies 3 are evenly distributed in a ring around the first gear assembly 2 and mesh with the first gear assembly 2 respectively. Each second gear assembly 3 includes a driven gear 31 and a second gear shaft 32 connecting the driven gear 31. Each second gear shaft 32 extends out of the bottom surface of the cover 1. The two ends of the second gear shaft 32 are axially connected to the cover 1, and the driven gear 31 and the driving gear 21 are in the same plane.

[0032] A plurality of rotating disks 4, the position and number of which correspond one-to-one with a plurality of second gear shafts 32, and the center of the top surface of each rotating disk 4 is connected to the corresponding second gear shaft 32;

[0033] Each of the rotating disks 4 has an eccentric rod 5 on its bottom surface, and each of the eccentric rods 5 has a collar 6 at its lower part. The collar 6 is used to fit the cryopreservation tube 9. The tube body of the cryopreservation tube 9 is adapted to the inner diameter of the collar 6, and the diameter of the tube cap of the cryopreservation tube 9 is larger than the inner diameter of the collar 6.

[0034] The crank handle 7 is connected to the first gear shaft 22.

[0035] This invention requires only the operator to place the cover 1 over the water bath and then directly crank the handle 7. The handle drives the first gear assembly 2 to rotate, which in turn drives multiple second gear assemblies 3 to rotate, causing multiple rotating disks 4 to rotate separately. Ultimately, this drives the eccentric rod 5 and the collar 6 to rotate; the eccentric rod 5 drives the collar 6 to perform circular motion. In this way, the cryopreservation tube 9 can achieve circular motion inside the water bath, instead of rotating around its own axis, which increases the shaking amplitude and makes the internal heating more uniform.

[0036] Based on the above technical solution, the cover 1 includes a top plate 11 and a bottom plate 12. The bottom plate 12 is provided with a plurality of connecting pins 13. The upper part of the connecting pin 13 is provided with a stepped shaft, and the upper part of the stepped shaft is provided with an external thread. The connecting pin 13 passes through the top plate 11, and the shoulder of the stepped shaft abuts against the bottom surface of the top plate 11. The upper part of the connecting pin 13 is provided with a locking nut 14, which engages with the external thread to fix the bottom plate 12 and the top plate 11. The split cover 1, which is composed of a flat top plate 11 and a bottom plate 12, is easier to install and disassemble, facilitates the maintenance of the internal first gear assembly 2 and second gear assembly 3, and also reduces the manufacturing difficulty.

[0037] Based on the above technical solution, the bottom surface of the cover 1 is provided with a sealing plate 8. The sealing plate 8 is made of rubber and is compatible with the edge of the water bath. It can be completely attached to the cover to prevent the warm water from splashing out of the water bath when it is shaken. It can also fix the cover 1 so that the operator does not need to pay attention to the position of the cover 1 on the water bath.

[0038] Based on the above technical solution, the collar 6 includes an outer ring 61 and an inner ring 62, the inner ring 62 is axially connected to the outer ring 61, and the inner ring 62 can rotate on the outer ring 61;

[0039] The outer ring 61 is provided with a pin 63, which is used to connect with the eccentric rod 5. The inner ring 62 is used to place the cryopreservation tube 9. When the cryopreservation tube 9 is placed in the inner ring 62, the center of gravity of the cryopreservation tube 9 is downward. The inner ring 62 can generally only sway left and right, thereby increasing the swaying amplitude of the cryopreservation tube 9 and allowing the internal cells and culture medium to be heated more evenly.

[0040] The pin 63 is inserted into the eccentric rod 5, allowing the outer ring 61 and the eccentric rod 5 to separate when the cryopreservation tube 9 is removed or placed, facilitating operation. It should be noted that the insertion of the pin 63 and the eccentric rod 5 is generally an interference fit, ensuring that the outer ring 61 remains as horizontal as possible and does not deflect. Furthermore, due to the interference fit, to facilitate operation, the eccentric rod 5 and the collar 6 are typically made of materials with moderate rigidity and a certain degree of elasticity. Considering the high moisture content of the operating environment, the materials are generally polymeric materials such as polytetrafluoroethylene (PTFE) and polyethylene.

[0041] Based on the above technical solution, the outer ring 61 is also provided with a handle 64, and the handle 64 is also provided with anti-slip protrusions. The handle 64 is for the operator to grip the outer ring 61, which facilitates the operation of disassembling and assembling the outer ring 61 and the eccentric rod 5, and avoids the fingers from directly contacting the cryopreservation tube 9.

[0042] In the above-mentioned content, this application not only allows the operator to concentrate on shaking the cryotube 9 without having to be distracted by controlling the stability of the cryotube 9, but also allows multiple rotating discs 4 to simultaneously drive multiple collars 6 and corresponding cryotubes 9 to rotate in the water bath, which can greatly improve the efficiency of cell revival.
