Description

Lifting mechanism capable of displaying lifting distance of suction pipe in container
Technical Field
The application relates to a lifting mechanism of liquid taking equipment in the biopharmaceutical industry, in particular to a lifting mechanism capable of displaying the lifting distance of a suction pipe in a container.
Background
Along with the rapid development of biopharmaceutical technology, small-sized pressure vessels such as fermentation tanks and seed tanks are widely used, and liquid in the tank needs to be extracted at different liquid levels in the tank by liquid extraction equipment such as a suction pipe in the production process.
On the one hand, the liquid level of the suction position of the existing suction pipe cannot be directly displayed, and after the suction pipe is lifted, the specific lifting distance is not clear, so that the suction of a sample with a specific liquid level in a container is inconvenient.
On the other hand, existing drive mechanisms for varying the height of the pipette are not accurate for distance control. For example, most of the existing driving mechanisms for changing the height of the suction tube are driving mechanisms composed of a motor and a mechanical arm, and fine adjustment of the height of the suction tube is difficult to be precise.
The Chinese patent publication No. CN115321406B discloses a worm gear screw type lifter, which has relatively high transmission precision. However, the motion form of the screw requires enough substances such as lubricating oil, and the screw can be directly exposed to air, while in the field of bio-pharmaceuticals, sterility is required in the production process, and the substances such as lubricating oil and the like are unavoidable to pollute the production environment, so that the screw type lifter in the patent is not suitable for the sterile environment and has room for improvement.

The lifting mechanism body 1 may include a fixing portion 11 and a lifting portion 12 capable of performing a lifting motion. The fixing portion 11 is connected to the container 4 via a first connector 21, and the lifting portion 12 is connected to the suction pipe 5 via a second connector 22. A suction tube 5 is inserted into the container 4 to suck the liquid in the container 4.
Wherein, scale 31 is connected to one of container 4, first connecting piece 21, fixed part 11, has scale mark on the scale 31. Referring to fig. 3, the scale mark can be designed to display the moving distance and the moving volume according to actual needs. For example, the liquid volumes corresponding to the suction ends of the suction pipes 5 at different heights in the container 4 can be calculated. The starting position of the suction pipe 5 in the container 4 is designed, and the starting position is taken as a zero point of the moving distance until the suction pipe 5 is lifted to the highest position designed as an end point of the moving distance (for example, 100mm in this case), and each position is corresponding to the liquid volume.
The scale pointer 32 is connected to one of the suction pipe 5, the second connector 22 and the lifting part 12, and in a state in which the lifting part 12 performs lifting movement, the suction pipe 5 can be lifted along with the lifting movement, and the scale pointer 32 can correspondingly point to different positions of scale marks so as to indicate the position of the suction pipe 5 in the container 4, so that the liquid level of the liquid sucked by the suction pipe 5 can be clearly and simply judged.
Further, referring to fig. 1, a scale 31 may be connected to the first connector 21, and a scale pointer 32 may be connected to the second connector 22. Referring to fig. 3, the scale 31 may include a scale connection hole 311, and the scale 31 may be screw-coupled with the first coupling member 21 through the scale connection hole 311. Referring to fig. 4, the scale pointer 32 may include a scale pointer connection hole 321, and the scale pointer 32 may be bolted to the second connection member 22 through the scale pointer connection hole 321. The scale pointer connection hole 321 may be a long hole, so as to facilitate fine adjustment of the position of the scale pointer 32, so that the scale 31 and the scale pointer 32 are more accurately matched.
Referring to fig. 1 and 5, in the thickness direction of the scale 31, the scale pointer 32 is opposite to the scale 31 in position, and the scale pointer 32 is located on one side of the scale 31 with scale marks, so that the scale pointer 32 can correspondingly point to the scale marks, which is convenient for an operator to view.
