[0002] The biological cell observation platform can be used to observe the division and activity of living cells. It is an important tool in the research of biology, medicine and other related fields. When observing cell adhesion, it is necessary to check the activity of cells at different positions of the cell culture bottle. The existing biological cell observation platform is equipped with a rotating clamping device. When the experimenter needs to observe the activity of cells at different positions, the rotating clamping device can be used to clamp the tilted cell culture bottle, so that the activity of the cells in the bottle can be directly observed.

Experimenters often need to observe multiple cell culture flasks. During the observation process, they need to change flasks many times and adjust the height and tilt angle. The operation is cumbersome and it is difficult to adjust all cell culture flasks to the same height and position, which can easily affect the accuracy of experimental detection and the work efficiency of experimenters.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, a biological cell observation platform includes a base 1, and a fill light device 2, an observation device 3, and a clamping mechanism 4 on the base 1; the clamping mechanism 4 is fixed at the middle position of the base 1, and the observation device 3 is movably installed on the top surface of the base 1 and is located at the side position of the clamping mechanism 4. The experimenter can adjust the position of the observation device 3 at any time according to the needs, which is convenient for the experimenter to obtain the best viewing angle for observing cells, and also helps them to observe and analyze biological cell samples more accurately. The fill light device 2 is fixed at the side position of the clamping mechanism 4.

[0036] Specifically, the clamping mechanism 4 of this embodiment includes a support column 41, an adjustment component 42, a moving component and a clamping piece 43; the support column 41 is fixed to the middle position of the base 1 by screw connection and is provided with an inner cavity; the moving component is sleeved on the outer side of the support column 41 and is movably connected to the support column 41; the adjustment component 42 is arranged in the inner cavity of the support column 41 and is fixedly connected to the moving component, and is used to control the moving component to move up and down on the support column 41; the clamping piece 43 is rotatably connected to the end position of the moving component. The moving component can be controlled to move up and down on the support column 41 by the adjustment component 42, and at this time, the clamping piece 43 on the moving component also moves vertically until the clamping piece 43 is adjusted to a suitable height. After adjusting the height of the clamping piece 43, the observation object can be quickly switched by rotating the moving component, which is convenient for the experimenter to observe the cell culture status efficiently and accurately, and improve the work efficiency and observation quality.

[0037] like Figure 2 As shown, the adjustment component 42 of this embodiment includes a rotating shaft 421, a knob, a first gear, a threaded rod 423, and a second gear; the rotating shaft 421 is horizontally placed in the inner cavity at the bottom end of the support column 41 and leads to the outer end of the support column 41, and the knob 422 is sleeved on both sides of the rotating shaft 421 leading to the outer end of the support column 41. Through the above arrangement, the rotation of the rotating shaft 421 can be achieved by rotating the knob 422 on the outside; there are two first gears, which are respectively sleeved on both sides of the rotating shaft 421 relative to each other. Through the above arrangement, it can be ensured that the first gear moves together with the rotation of the rotating shaft 421; there are two threaded rods 423, which are respectively vertically arranged on both sides of the inner cavity of the support column 41, and there are two second gears. They are respectively sleeved on the bottom ends of the threaded rod 423 in the same direction and meshed with the first gear. Through the above arrangement, when the knob 422 is rotated on the outside of the support column 41, the rotating shaft 421 and the first gear on the rotating shaft 421 can be driven to rotate, and then the second gear and the threaded rod 423 are driven to move together through the transmission action of the first gear. Since the two first gears are arranged relatively to each other, the threads on the two threaded rods 423 are in opposite directions, ensuring that the two threaded rods 423 move in the same direction. The above arrangement makes it easy for experimenters to control the movement of the moving component on the support column 41 through the adjustment component 42, thereby realizing the adjustment of the height of the culture bottle, which is convenient for experimenters to observe the growth of cells.

[0038] like Figure 2 As shown, the moving assembly of this embodiment includes a lifting plate 5 and a turntable 6; the lifting plate 5 is fixed on the threaded rod 423 by a threaded connection and extends to the outside of the support column 41 to wrap the support column 41, and the lifting plate 5 is pushed up and down relative to the support column 41 by the rotation of the threaded rod 423; the turntable 6 is installed in the middle of the lifting plate 5 and is sleeved on the outer end of the support column 41 and is rotatably connected to the lifting plate 5. Through the above arrangement, when the lifting plate 5 is moved, the turntable 6 can also move up and down accordingly. When it is necessary to switch the observation object, the bi experimenter can quickly switch the observation object by rotating the turntable 6, which is convenient for the experimenter to quickly observe the growth conditions of cells in different culture bottles.

[0041] The turntable 6 of this embodiment is provided with positioning grooves and slide rails; the positioning grooves are provided at the bottom of the turntable 6 and are mutually engaged with the tops of the positioning beads, and there are four positioning grooves, which are provided directly above the accommodating grooves 521; the slide rails are provided at the bottom of the turntable 6 to provide good sliding conditions for the positioning beads, so that the positioning beads can move smoothly at the bottom of the turntable 6. By providing the positioning grooves, it is convenient for the experimenter to rotate the turntable 6 at a fixed angle and fix it.

[0042] like Figure 2 As shown, the clamping member 43 of the present invention is rotatably connected to the outer side of the turntable 6. The clamping member 43 is provided with at least two clamping holes of different sizes, which can be used to clamp culture bottles of different specifications and sizes, making it convenient for experimenters to fix culture bottles of different sizes.
