[0029] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and implementation methods. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] like Figure 1-Figure 3 As shown, this embodiment provides a tilting and rotating device, including a culture plate 1, an angle adjustment component 2, a tilt holding component 3 and a driving member 4, wherein a culture dish is fixedly arranged on the culture plate 1, one end of the angle adjustment component 2 is connected to the culture plate 1, and can adjust the angle between the culture plate 1 and the horizontal plane; the tilt holding component 3 is sleeved on the angle adjustment component 2, and one end abuts against the lower end surface of the culture plate 1, and is used to support the culture plate 1 to maintain the angle with the horizontal plane; the other end of the angle adjustment component 2 is transmission-connected to the output end of the driving member 4, and the driving member 4 is used to drive the culture plate 1 to rotate. Using the tilting and rotating device provided in this embodiment, the culture plate 1 can be adjusted to a certain tilt angle and the tilt angle of the culture plate 1 can be maintained by the tilt holding component 3.

[0033] After adding the cell culture medium, the uniform rotation of the driving member 4 drives the culture dish on the culture plate 1 to rotate uniformly at a certain inclination angle, so that the added cell culture medium is evenly spread on the cells. Compared with the prior art which requires manual shaking of the culture medium in the culture dish, the tilting rotation device provided in this embodiment can control the inclination angle and speed when shaking the cell culture medium, and the shaking is in place, so that the cells can be evenly spread in the cell culture medium, and the culture dish will not fall off easily during the shaking process.

[0034] Specifically, the angle adjustment assembly 2 includes a first connecting rod 21, a second connecting rod 22 and a transmission adapter 23. One end of the first connecting rod 21 is connected to the culture plate 1, and the other end is hinged to the second connecting rod 22. The upper end of the transmission adapter 23 is hinged to the second connecting rod 22. The transmission adapter 23 is connected to the output end of the driving member 4. The inclination angle maintaining assembly 3 can drive the first connecting rod 21 to move up and down. At this time, the second connecting rod 22 rotates around the hinge with the transmission adapter 23, and the first connecting rod 21 rotates around the hinge with the second connecting rod 22 accordingly, so that the culture plate 1 can be rotated to tilt at a certain angle to the horizontal plane. Starting the driving member 4 can complete the tilt rotation and shake the cell culture medium.

[0035] Furthermore, the transmission adapter 23 includes a first connecting plate and a second connecting plate arranged in parallel and spaced apart. The first connecting plate is provided with a first mounting groove, and the second connecting plate is provided with a second mounting groove. The output end of the driving member 4 is clamped between the first mounting groove and the second mounting groove. The first connecting plate and the second connecting plate are tightened together by bolts to hold the output end of the driving member 4, so that the transmission connection is firm and the rotation is uniform and stable. At the same time, it is convenient for installation and disassembly. The second connecting rod 22 is hinged to the first connecting plate and the second connecting plate, and the angle adjustment is flexible.

[0036] Specifically, the inclination angle maintaining assembly 3 includes a tilting support assembly, a telescopic maintaining assembly 32 and a limiter 33. The telescopic maintaining assembly 32 is sleeved on the angle adjustment assembly 2. The tilting support assembly is rotatably arranged on the telescopic maintaining assembly 32 and sleeved on the angle adjustment assembly 2. The telescopic maintaining assembly 32 can drive the tilting support assembly and thus drive the culture plate 1 to have a certain inclination angle with the horizontal plane. The limiter 33 is used to limit the telescopic height of the telescopic maintaining assembly 32. Furthermore, the limiter 33 is a linear motor. The linear motor directly generates linear motion, has high positioning accuracy, is stable and reliable, and is easy to operate and maintain. In other embodiments, the limiter 33 can also use a fixing pin, and the fixing pin supports the telescopic maintaining assembly 32 to maintain a certain telescopic height.

[0037] Furthermore, the tilting support assembly includes a support ring 31, and the telescopic holding assembly 32 includes a first sleeve 321 and a second sleeve 322. The first sleeve 321 is slidably sleeved on the second sleeve 322, and the second sleeve 322 guides the telescopic sliding of the first sleeve 321 to ensure that the first sleeve 321 does not generate horizontal shaking during the telescopic process. The support ring 31 is rotatably set on the first sleeve 321 through two rotating pins, and can flexibly rotate with the tilt of the culture plate 1. The second sleeve 322 is fixedly set on the driving member 4, and the angle adjustment assembly 2 is located in the second sleeve 322 to prevent external dust from falling into the device and thus reducing the service life of the device. The output end of the linear motor is fixedly set on the second sleeve 322, and the other end abuts on the first sleeve 321. The linear motor can drive the first sleeve 321 to reciprocate in the vertical direction to adjust the tilt angle of the culture plate 1.

[0038] Furthermore, a protrusion 3211 is convexly provided on the outer peripheral surface of the first sleeve 321 , and the linear motor abuts against the protrusion 3211 , so that the transmission is stable when the first sleeve 321 is extended or retracted.

[0039] Furthermore, the second sleeve 322 includes a mounting portion 3221 and a sliding portion 3222 which are coaxially connected to each other. The first sleeve 321 is movably sleeved on the sliding portion 3222 and can abut against the mounting portion 3221. The mounting portion 3221 can limit the first sleeve 321. At the same time, the mounting portion 3221 is fixedly connected to the driving member 4 by bolts to increase the overall stability of the device.

[0040] Specifically, a plurality of mounting grooves are provided on the culture plate 1, and a culture dish is correspondingly arranged in each mounting groove, so that the shaking operation of multiple groups of cell culture fluids can be completed at one time.

[0041] Furthermore, a cover is provided on the culture dish, which is hinged on the culture dish and can open and close the culture dish to prevent the cell culture fluid and cells from being thrown out of the culture dish during the shaking operation.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
