Description

Technical Field

[0001] The utility model belongs to the technical field of shaking cell culture dishes, in particular to a device for shaking stacked cell culture dishes. Background Art

[0002] Cell culture is a basic experimental technique in the fields of biomedical research and biotechnology, and is widely used in gene editing, drug screening, vaccine development, and cell therapy. During the cell culture process, in order to ensure that the cells are evenly distributed and fully in contact with the culture medium, it is usually necessary to shake the culture dish. Most of the existing cell culture dish shaking devices are only suitable for shaking a single culture dish. The culture dish is fixed to the shaking table with a rubber band. This method has the following problems: Low efficiency: The existing device can only shake one culture dish at a time, which cannot meet the needs of high-throughput experiments and limits the efficiency of the experiment. Inconvenient operation: The culture dishes need to be installed and removed one by one, which is cumbersome and prone to errors, increasing the labor intensity of the experimenter. In view of the above problems, it is necessary to design a device that can shake multiple stacked cell culture dishes at the same time to improve experimental efficiency and stability, simplify the operating process, and enhance applicability and convenience.

The protective frame 4 is plugged and mounted on the cradle 3.

[0029] The cradle 3 includes a square horizontal carrier plate 31. A cylindrical rod 32 is fixed to the center of the lower surface of the horizontal carrier plate 31, which rotatably engages the second circular sleeve 23. A column 33 is fixed to each of the four corners of the lower surface of the horizontal carrier plate 31. The housing 11 is a rectangular structure, with a rubber foot at each corner of its bottom surface. Four third circular sleeves 15 are fixed to the top surface of the housing 11, which rotatably engage the four columns 33. A ball 34 is rotatably mounted at the lower end of the column 33. Four sockets 35 are provided on the upper surface of the horizontal carrier plate 31, which plug into the protective frame 4. The four sockets 35 are symmetrically arranged about the axis of the horizontal carrier plate 31. The cradle 3 is provided with four columns 33 for balanced support. Balls 34 are positioned at the lower ends of the columns 33, which are in rolling connection with the top surface of the cradle base 1.
