[0002] Cell culture is a crucial foundational science in biology, medicine, and drug discovery. By simulating the in vivo environment, cells can survive, grow, and reproduce in vitro, maintaining their primary structure and function. This is crucial for vaccine production, genetically engineered drugs, and cell-engineered drugs. Cell culture itself involves large-scale cell cloning, and culture dishes are essential components of this process. While manual transfer of culture dishes is sufficient for small quantities, a cell culture dish transfer device is required for large-scale transfers.

[0003] Existing cell culture dish transfer devices have poor fixation effects on culture dishes, and culture dishes are prone to collision. For example, the utility model patent with application number 202123294902.5 discloses a cell culture dish transfer device. This cell culture dish transfer device solves the problem of limited number of culture dishes transferred by hand, can transfer more culture dishes at a time, avoids the phenomenon of easy scattering and instability when transferring culture dishes by hand, can ensure high safety, and there is no need to worry about culture dishes scattering during the transfer process. It has good stability, avoids the easy shaking of culture dishes transferred by hand, which leads to uneven distribution of cells in the dish, and can keep it level during the transfer process, so that the cell distribution is not affected.

[0004] However, when using the cell culture dish transfer device, the two sets of curved limit plates only clamp and secure the culture dishes on the surface of the carrier plate. The culture dishes stacked in groups above are not clamped and secured. This makes it easy for the upper culture dishes to shift and wobble during transfer. Furthermore, during use, friction and collisions between the culture dishes may occur, affecting their stability.

[0005] Therefore, it is necessary to develop a cell culture dish transfer device to address the above defects. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] In one embodiment, Figures 1 to 3 As shown, it includes a transfer box 1, a box cover 2 that can be opened and closed is hinged on one side of the top surface of the transfer box 1, and several placement plates 3 are slidably connected in the transfer box 1. The top surface of each placement plate 3 is provided with several placement slots 5 for placing cell culture dishes 4, and a threaded hole 6 is provided on the placement plate 3 on one side of each placement slot 5, and a clamping assembly is threadedly connected to the threaded hole 6; the clamping assembly includes a threaded rod 7, a rotating shaft 8, a limiting plate 9 and a pressing plate 10, the threaded rod 7 is threadedly connected to the threaded hole 6, the rotating shaft 8 is fixedly connected to the top surface of the threaded rod 7, there are two limiting plates 9 and they are respectively fixedly connected to the two ends of the rotating shaft 8, and one end of the pressing plate 10 is fixedly connected to a swivel 11, which is sleeved and rotatably connected to the rotating shaft 8.

[0027] By setting the placement tray 3, the cell culture dish 4 can be placed in a number of independent placement slots 5 in sequence, and the threaded rod 7 in the clamping assembly on one side of each placement slot 5 is screwed into the threaded hole 6 to drive the pressure plate 10 to move down until the bottom surface of the pressure plate 10 conflicts with the top surface of the cell culture dish 4. By rotating the rotating shaft 8 of the pressure plate 10 on the threaded rod 7, the position of the pressure plate 10 can be adjusted so that it can be pressed in the middle position of the top surface of the cell culture dish 4, thereby pressing and fixing the cell culture dish 4 in the placement slot 5 of the placement tray 3 to prevent the cell culture dish 4 from shifting and shaking. By setting two limiting plates 9, the rotating ring 11 can be limited to prevent the pressure plate 10 from sliding up and down on the rotating shaft 8. By stacking a number of placement trays 3 in the transfer box 1, friction and shaking between two adjacent layers of cell culture dishes 4 can be prevented, thereby improving the stability of the transfer of the cell culture dishes 4.

[0028] In a specific embodiment, the length of the pressing plate 10 is the same as the distance from the center of the placement groove 5 to the threaded hole 6, so that the top of the pressing plate 10 can be exactly located at the center position of the cell culture dish 4. The other end of the pressing plate 10 is fixedly connected to a pressure plate 12. The pressure plate 12 is a circular disc with a diameter smaller than the cell culture dish 4. Through the setting of the pressure plate 12, the contact area with the cell culture dish 4 can be increased, thereby improving the pressing effect on the cell culture dish 4.

[0029] Specifically, the bottom surfaces of the pressing plate 10 and the pressing plate 12 are fixedly connected with rubber pads 13. By providing the rubber pads 13, the pressing plate 10 and the pressing plate 12 can be prevented from directly contacting the cell culture dish 4, thereby effectively protecting the cell culture dish 4 and increasing the friction between the cell culture dish 4.

[0030] In one embodiment, a plurality of vertical guide rails 14 are fixedly connected to the inner wall of the transfer box 1, and a plurality of corresponding chute grooves 15 are formed on the placement tray 3. The chute grooves 15 are slidably engaged with the guide rails 14. The arrangement of the guide rails 14 and the chute grooves 15 allows the placement tray 3 to be slidably guided when being placed in and removed from the transfer box 1, thereby facilitating the movement of the placement tray 3 in the transfer box 1.

[0031] In one embodiment, grooves 16 are symmetrically formed on the placement tray 5 on both sides of the placement slot 5, and the grooves 16 are connected to the placement slot 5. The provision of the grooves 16 makes it convenient for a worker to insert their fingers into the grooves 16 to grab and place the cell culture dish 4, thereby facilitating the placement and removal of the cell culture dish 4 from the placement tray 3.

[0032] In a specific embodiment, a pull rod 17 is fixedly connected to the middle position of the top surface of the placement tray 3. Through the arrangement of the pull rod 17, it is convenient for the staff to hold the pull rod 17 to lift the placement tray 3, which is convenient for placing and taking out the placement tray 3 in the transfer box 1.

[0033] Specifically, support columns 18 are fixedly connected to the four corners of the bottom surface of the placement tray 3. The length of the support columns 18 is not less than the length of the tie rods 17. The arrangement of the support columns 18 can provide a gap between two adjacent placement trays 3 in the transfer box 1, so that the tie rods 17 on the top surface of the placement tray 3 do not contact the bottom surface of the adjacent placement tray 3 above it, ensuring that the placement tray 3 is stably placed in the transfer box 1.

[0034] In one embodiment, the outer wall of the transfer box 1 is provided with handles 19, each hinged at its ends to two opposing outer walls of the transfer box 1. There are two handles 19. The provision of handles 19 facilitates a worker's grasp of the handles 19 to lift and transfer the transfer box 1. The two handles 19, each hinged at its ends to two identical outer walls, prevent the transfer box 1 from shaking when the handles 19 are lifted.

[0035] Working principle of the present invention: When the cell culture dish transfer device of the present invention is used, the placement trays 3 in the transfer box 1 are first taken out in turn, and then the cell culture dishes 4 are placed in the independent placement slots 5 in each placement tray 3 in turn. The threaded rod 7 in the clamping assembly on one side of each placement slot 5 is screwed into the threaded hole 6, driving the pressure plate 10 to move down until the bottom surface of the pressure plate 10 conflicts with the top surface of the cell culture dish 4. By rotating the rotating shaft 8 of the pressure plate 10 on the threaded rod 7, the position of the pressure plate 10 can be adjusted so that it can be pressed in the middle position of the top surface of the cell culture dish 4, thereby pressing and fixing the cell culture dish 4 in the placement slot 5 of the placement tray 3 to prevent the cell culture dish 4 from shifting and shaking. By setting two limiting plates 9, the rotating ring 11 can be limited to prevent the pressure plate 10 from sliding up and down on the rotating shaft 8. By stacking several placement trays 3 in the transfer box 1, friction and shaking between two adjacent layers of cell culture dishes 4 can be prevented, thereby improving the stability of the transfer of the cell culture dishes 4. Finally, the handheld pull rod 17 is used to stack the placement trays 3 one by one in the transfer box 1, and the box cover 2 is closed to transfer the culture dishes.

[0036] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments.
