[0034] refer to Figures 1 to 3 The utility model provides an oscillating incubator, comprising a rocking plate 1 and a base 2; a cam motion structure 3 and a flexible support column 21 are provided on the base 2, and both ends of the flexible support column 21 are respectively fixedly connected to the rocking plate 1 and the base 2, the cam motion structure 3 is connected to the rocking plate 1 and is suitable for driving the rocking plate 1 to oscillate slightly, and the middle part of the flexible support column 21 is deformed following the oscillation of the rocking plate 1.

[0035] In this embodiment, the two ends of the flexible support column 21 are fixedly connected to the rocking plate 1 and the base 2 respectively, and the middle part of the flexible support column 21 produces corresponding deformation to adapt to the oscillation frequency of the rocking plate 1, reducing the inertia of the oscillation of the rocking plate 1, so that the cam motion structure 3 can control the oscillation of the rocking plate 1 more smoothly, and the connection between the cam motion structure 3 and the rocking plate 1 is more stable and effective, and is not easy to be damaged or separated.

[0036] Specifically, the shaking plate 1 is suitable for placing a culture container such as a culture cup or a culture box, and the shaking plate 1 drives the culture container to oscillate. Figures 3 to 5 The cam motion structure 3 includes a motor 31, a cam 32 and a bearing 33. The motor 31 is mounted on the base 2. The drive shaft of the motor 31 is connected to the cam 32. The bearing 33 is connected to the rocking plate 1 and the cam 32, so that the rotation of the cam 32 can drive the rocking plate 1 to rock back and forth and left and right. The cam motion structure 3 can be understood as an eccentric wheel rotation structure, which realizes the oscillation of the rocking plate 1 through the eccentric movement of the cam 32.

[0037] refer to Figure 2 , there are preferably four flexible support columns 21, which are respectively arranged at the four corners of the rocking plate 1 and relatively located at the four corners of the cam motion structure 3. The distribution of the flexible support columns 21 is more reasonable, the movable structure strength of the rocking plate 1 and the base 2 is higher, and it is more difficult to separate or tilt. The flexible support columns 21 can best support and assist the rocking plate 1, prevent the rocking plate 1 from tilting or tipping, and ensure that the rocking plate 1 can still be set horizontally when following the oscillation of the cam motion structure 3, and the oscillation of the culture container on the rocking plate 1 is more stable and reliable. The number of flexible support columns 21 in this application is not further limited in this application, as long as it can increase the stability and regularity of the oscillation of the rocking plate 1. The two ends of the flexible support column 21 are respectively fixedly connected to the rocking plate 1 and the base 2. A plurality of locking holes 11 are provided on the rocking plate 1 and the base 2. A plurality of locking channels are also provided in the axial middle of the flexible support column 21. The locking member is fixed in the locking channel through the locking hole 11. It should be noted that the locking member only fixes the two ends of the flexible support column 21, so the two ends of the flexible support column 21 do not move, and the middle part of the flexible support column 21 can deform accordingly with the oscillation of the rocking plate 1 due to its material properties. The locking member includes but is not limited to screws and the like. The end of the flexible support column 21 close to the rocking plate 1 shakes with the oscillation of the rocking plate 1, the end of the flexible support column 21 away from the rocking plate 1 remains still with the base 2, and the end of the flexible support column 21 close to the rocking plate 1 shakes and drives the middle section of the flexible support column 21 to bend and deform slightly. When in use, the motor 31 drives the cam 32 to rotate irregularly at a high speed, and the cam 32 drives the rocking plate 1 to oscillate left and right and forward and backward. At this time, the rocking plate 1 can be regarded as rotating. The oscillation of the rocking plate 1 causes one end of the flexible support column 21 to be displaced relative to the other end, causing the middle section of the flexible support column 21 to deform and provide a reaction force opposite to the oscillation direction, which is used to reduce the inertia of the rocking plate 1 in this oscillation direction, so that the subsequent cam motion structure 3 can effectively and controllably drive the rocking plate 1 to oscillate in other directions, so that the rocking plate 1 can oscillate and rotate more regularly. It is worth noting that the oscillation movement of the cam motion structure 3 is slight, and preferably the oscillation range of the rocking plate 1 is 1.5mm, which will only drive the rocking plate 1 to oscillate slightly, so the deformation of the flexible support column 21 is also slight, and the flexible support column 21 will not deform at a large angle or a large length, is not easy to deform and damage, and has extremely strong practicality. The material of the flexible support column 21 includes but is not limited to soft materials such as rubber, and this application does not make further restrictions.

[0038] Further, refer to Figure 5 The cam motion structure 3 also includes a flange 34 , which is fixedly connected to the rocking plate 1 and an end of the bearing 33 away from the cam 32 .

[0039] Specifically, the end of the flange 34 away from the base 2 has a mounting cavity 341, and a first fixing plate 342 and a second fixing plate 343 are provided in the mounting cavity 341. The first fixing plate 342 is fixedly connected to the top of the cam 32 and abuts against an end of the bearing 33 close to the cam 32; the second fixing plate 343 is fixedly connected to the flange 34 and abuts against an end of the bearing 33 away from the cam 32. The first fixing plate 342 and the second fixing plate 343 can increase the structural strength of the cam motion structure 3, prevent the bearing 33 from separating when the cam motion structure 3 rotates at a high speed, and are more durable and reliable.

[0040] Further, refer to Figure 1 and Figure 2 At least two groups of cam motion structures 3 and at least two groups of rocking plates 1 are arranged on the base 2 at intervals. Each group of cam motion structures 3 controls a group of rocking plates 1 separately. At least four flexible support columns 21 are arranged around each group of cam motion structures 3.

[0041] In this embodiment, a plurality of cam motion structures 3 are arranged at intervals on the base 2, each cam motion structure 3 is connected to a rocking plate 1, and each rocking plate 1 can be controlled individually to meet different experimental requirements and improve the use range and applicability of the shaking incubator.

[0042] Specifically, two groups of cam motion structures 3 are arranged side by side on the base 2, each cam motion structure 3 is connected to a group of rocking plates 1, and eight flexible support columns 21 are also provided on the base 2, and every four flexible support columns 21 are respectively arranged at the four corners of the cam motion structure 3, so that the two rocking plates 1 are completely independent, and every four flexible support columns 21 can provide independent and effective support for each rocking plate 1. Of course, the number of flexible support columns 21 in the present application includes but is not limited to eight. In another embodiment, six flexible support columns 21 can also be provided on the base 2, two flexible support columns 21 are arranged on one side of a cam motion structure 3, and the other two cam motion structures 3 are arranged on the other side of another cam motion structure 3, and the last two cam motion structures 3 are arranged between the two groups of cam motion structures 3.

[0044] In this embodiment, the protective cover 4 is mounted above the base 2 and is arranged between the rocking plate 1 and the base 2 to prevent the rocking plate 1 from tipping over in the event of an accident, causing greater losses. It can also prevent foreign matter from entering the cam motion structure 3, thereby increasing the safety of the cam motion structure 3.

[0045] Specifically, the protective cover 4 is provided with a plurality of first holes 41, through which the cam motion structure 3 passes, and the diameter of the first hole 41 is larger than that of the cam motion structure 3. The protective cover 4 is also provided with a plurality of second holes 42, through which the flexible support column 21 passes, and the diameter of the second hole 42 is larger than that of the flexible support column 21. It is worth noting that the first hole 41 and the second hole 42 need to take into account the oscillation amplitude of the rocking plate 1, and the diameter of the first hole 41 needs to be larger than the sum of the diameter of the cam motion structure 3 and the oscillation amplitude of the rocking plate 1. The diameter of the second hole 42 needs to be larger than the sum of the diameter of the convex flexible support column 21 and the oscillation amplitude of the rocking plate 1.

[0046] Further, refer to Figure 3 A fixing column 22 is also provided on the protective cover 4 . The fixing column 22 is relatively arranged in the middle of the adjacent flexible support columns 21 . The fixing column 22 is relatively placed in the cover body cavity 40 and fixedly connects the protective cover 4 and the base 2 .

[0047] In this embodiment, the fixing column 22 is fixedly connected to the protection cover 4 and the base 2 . The fixing column 22 is relatively arranged in the middle of the adjacent flexible support columns 21 , and the structure is stable.

[0048] Specifically, the bottom of the protective cover 4 is flush with the bottom of the base 2, and the fixing column 22 is fixedly connected to the top inner wall of the protective cover 4 and the top outer wall of the base 2, so that the fixing column 22 is relatively located inside the cover body cavity 40, which is more beautiful and not easy to be damaged.

[0049] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
