Technical Field

[0001] The utility model relates to the technical field of cell culture, in particular to a cell culture shaking table. Background Art

[0002] The biological shaker is a common laboratory instrument, mainly used for bacterial culture, fermentation, hybridization and biochemical reaction, as well as enzyme and cell tissue culture research. It is widely used in medicine, biology, pharmaceuticals, food, and other industries.

[0003] In the prior art, when the existing shaker is culturing the culture container, because the shaker needs to shake during operation, each culture container needs to be fixed on the shaker. When fixing the culture dish, the existing shaker equipment needs to fix each culture container in turn, which requires the staff to spend a lot of time on fixing and releasing the culture container, reducing work efficiency. In addition, since the culture container has a variety of different specifications and sizes, the clamps corresponding to the size of the culture container need to be used to fix the culture containers of different sizes, which has low applicability. Therefore, the present application specifically proposes a cell culture shaker that can uniformly fix culture containers of different specifications. Utility Model Content

[0004] The main purpose of the utility model is to provide a cell culture shaking table which can uniformly fix culture containers of different specifications.

[0005] To achieve the above object, the utility model provides a cell culture shaker, comprising:

[0006] A constant temperature platform, used to provide a suitable culture environment for the cells to be cultured;

[0007] A support, slidably disposed on the constant temperature platform, for placing the culture container and driving the culture container to shake;

[0008] A shaking component is arranged in the constant temperature table, and one end of the shaking component is connected to the bottom of the support, and is used to drive the support to move in a circular manner around the center of the constant temperature table on the constant temperature table;

The clamping components are used to clamp the culture container. The clamping group further includes a lead screw rotatably inserted into the support. One end of the lead screw extends out of the support and is provided with a rotating handle. Each of the clamping components includes two oppositely arranged clamping blocks and an adjusting member connected to each clamping block. The adjusting member includes an abutting block, a limiting portion, and a moving block. The abutting block is connected to the clamping block and drives the clamping block to move. One end of the moving block is slidably arranged in the abutting block, and the other end is screwed with the lead screw. The limiting portion is arranged in the abutting block and is used to limit the relative position of the moving block and the abutting block when the clamping force is less than a predetermined value, and release the limit on the moving block when the clamping force exceeds the predetermined value.

[0010] Further, a plurality of notches are formed in the support, and the positions of the notches are distributed relative to the clamping components. The lead screw is provided with a thread group corresponding to each clamping component one by one. The thread group is composed of two threads with opposite helix directions.

The limiting portion includes limiting blocks rotatably arranged on both sides of the chute. The limiting blocks are arranged in a "丿" shape, and the straight section of the limiting block is arranged along the movement direction of the abutting block. The inclined section of the limiting block extends out of the abutting block and abuts against the clamping block. The rotating joint of the limiting block is arranged at one end of the straight section of the limiting block away from the clamping block. The limiting portion further includes an elastic unit arranged between the end of the abutting block close to the clamping block and the side wall of the corresponding chute.

[0012] The other end of the moving block is threadedly connected to the corresponding thread group, and the two moving blocks in the adjusting member are respectively screwed on the two threads of the corresponding thread group. When the lead screw rotates, the corresponding two moving blocks drive the abutting block to approach or move away from each other on the support through the thread group, so that the abutting block pushes the corresponding clamping blocks to approach each other until the culture container is clamped.

[0016] Furthermore, a lining is provided on one side of the clamping block close to the culture container, and when the clamping block clamps the culture container, the lining is used to protect the culture container.

[0017] Furthermore, a protective cover is provided on the constant temperature platform, and the protective cover is arranged around the support to isolate the working environment of cell culture from the external environment.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0029] See also Figure 1-Figure 6 .

[0030] The utility model discloses a cell culture shaking table, comprising:

[0031] A constant temperature platform 1, used to provide a suitable culture environment for cells to be cultured;

[0032] The support 2 is slidably disposed on the constant temperature platform 1, and is used to place the culture container 8 and drive the culture container 8 to shake;

[0033] A shaking component 3 is arranged in the constant temperature platform 1, and one end of the shaking component 3 is connected to the bottom of the support 2, and is used to drive the support 2 to move in a circular manner around the center of the constant temperature platform 1 on the constant temperature platform 1;

[0034] At least one clamping group, the clamping group includes a plurality of clamping parts 4, each clamping part 4 is arranged in a straight line on the support 2, the clamping part 4 is used to clamp the culture container 8, the clamping group also includes a lead screw 412 rotatably inserted in the support 2, one end of the lead screw 412 extends out of the support 2 and is provided with a rotating handle 4122, each clamping part 4 includes two clamping blocks 41 arranged opposite to each other and an adjusting member 42 connected to each clamping block 41, the adjusting member 42 includes abutting Block 421, a limiting portion 422 and a moving block 423, the abutting block 421 is connected to the clamping block 41 to drive the clamping block 41 to move, one end of the moving block 423 is slidably set in the abutting block 421, and the other end is screwed with the lead screw 412, the limiting portion 422 is set in the abutting block 421, and is used to limit the relative position of the moving block 423 and the abutting block 421 when the clamping force is less than a predetermined value, and release the limiting of the moving block 423 when the clamping force exceeds the predetermined value.

[0035] After the culture containers 8 are placed, the staff will rotate the handle 4122 to rotate the lead screw 412, thereby driving the abutment block 421 to move toward the clamping block 41 through the moving block 423, so that the two clamping blocks 41 on the same clamping component 4 are relatively close to each other. During the rotation of the lead screw 412, the culture container 8 with a larger specification will be clamped by the corresponding clamping component 4 first. At this time, the lead screw 412 continues to rotate, and the clamping force in the clamping component 4 that has clamped the culture container 8 exceeds the predetermined value. The limit part 422 releases the constraint on the moving block 423 and then limits the moving block 423 again. The moving block 423 moves in the corresponding abutment block 421 until the culture container 8 with a smaller specification is clamped. When all the culture containers 8 are clamped, the staff will start the shaking component 3, and the shaking component 3 drives the support 2 to move in a circle around the center of the constant temperature table 1 on the constant temperature table 1, thereby driving the culture container 8 to shake.

[0036] The utility model can uniformly fix the culture containers 8 clamped by each adjusting member 42 on the screw 412 by rotating the screw 412, thereby improving the work efficiency, and the clamping force when the adjusting member 42 tightens the clamping block 41 is controlled by the limit portion 422, so that the clamping blocks 41 in the clamping group can clamp culture containers 8 of different specifications and sizes and uniformly fix them, thereby increasing the applicability.

[0037] In one embodiment, the support 2 is provided with a plurality of notches 21, and the notches 21 are arranged in a distributed manner relative to the clamping member 4. The lead screw 412 is provided with a thread group 4121 corresponding to each clamping member 4 one by one, and the thread group 4121 is composed of two sections of threads with opposite rotation directions.

[0038] The clamping block 41 is semi-circular, and each clamping block 41 is slidably arranged on the support 2 along the installation direction of the lead screw 412. The abutting block 421 is arranged on the side of the corresponding clamping block 41 away from the culture container 8. The abutting block 421 is slidably arranged on the support 2 along the installation direction of the lead screw 412. A chute 4211 is formed at the bottom end of the abutting block 421. The limiting part 422 includes limiting blocks 4221 rotatably arranged on both sides of the chute 4211. The limiting blocks 4221 are arranged in a shape of "丿", and the straight section of the limiting block 4221 is arranged along the moving direction of the abutting block 421. The inclined section of the limiting block 4221 extends out of the abutting block 421 and abuts against the clamping block 41. The rotating joint of the limiting block 4221 is arranged at one end of the straight section of the limiting block 4221 away from the clamping block 41. The limiting part 422 further includes an elastic unit 4222 arranged between the end of the abutting block 421 close to the clamping block 41 and the side wall of the corresponding chute 4211. The elastic unit 4222 is used to provide an elastic force for the limiting block 4221 towards the center direction of the abutting block 421. The above-mentioned moving block 423 is arranged below the abutting block 421. The top end of the moving block 423 passes through the corresponding notch 21 on the support 2 and is slidably arranged in the chute 4211, and the top end of the moving block 423 is located between the two limiting blocks 4221. The elastic unit 4222 is used to push the limiting block 4221 to clamp both sides of the moving block 423;

[0039] The other end of the moving block 423 is threadedly connected to the corresponding thread group 4121. The two moving blocks 423 in the adjusting member 42 are respectively screwed onto the two sections of threads of the corresponding thread group 4121. When the lead screw 412 rotates, the corresponding two moving blocks 423 drive the abutting block 421 to approach or move away from each other on the support 2 through the thread group 4121, so that the abutting block 421 pushes the corresponding clamping blocks 41 to approach each other until the culture container 8 is clamped.

[0040] With this design, when it is necessary to clamp the culture container 8, the lead screw 412 is rotated, and the two moving blocks 423 on the same thread group 4121 approach each other, and each moving block 423 drives the corresponding group of abutment blocks 421 to approach each other, until the limit block 4221 abuts on the clamping block 41 and drives the clamping blocks 41 to approach each other until the clamping block 41 clamps the culture container 8. When a culture container 8 with a larger specification in a clamping group is clamped, the corresponding clamping block 41 has abutted and clamped the outer wall of the culture container 8 with a larger specification, but the culture container 8 with a smaller specification has not been clamped and fixed. At this time, the lead screw 412 is continued to be rotated, and the clamping force in the corresponding adjusting member 42 that has been clamped exceeds a predetermined value, and the corresponding limit block 4221 abuts against the clamping block 41 and drives the clamping blocks 41 to approach each other until the clamping block 41 clamps the culture container 8. The end of block 4221 contacting the clamping block 41 is subjected to the reaction force of abutting the clamping block 41 and compresses the elastic unit 4222. The limit block 4221 rotates away from the center of the moving block 423. At this time, the two sides of the moving block 423 lose their constraints and slide in the slide groove 4211, and the clamping block 41 loses its clamping force. During the sliding process of the moving block 423, the spring drives the limit block 4221 to reset, and the limit block 4221 clamps the moving block 423 again. The moving block 423 makes the clamping block 41 clamp the culture container 8 again through the limit block 4221 until the culture containers 8 on the corresponding clamping group are all clamped and fixed. At this time, the clamping force of the clamping block 41 on the culture container 8 is equal to the elastic force of the elastic unit 4222.

[0041] Preferably, the elastic unit 4222 may adopt a spring in the prior art.

[0042] It should be noted that the spring has sufficient elastic force. When the limit block 4221 abuts against and pushes the clamping block 41, the spring will not be compressed due to the reaction force of the clamping block 41 on the limit block 4221 during the pushing process, thereby ensuring that the moving block 423 can smoothly drive the moving block 423 to move before the clamping block 41 abuts against the culture container 8.

[0043] In one embodiment, a reset component 5 is provided on each adjusting member 42, and the reset component 5 includes a first L-plate 51 arranged on the top of each abutment block 421, and each clamping block 41 is provided with a second L-plate 52 on the side close to the corresponding first L-plate 51, and the first L-plate 51 and the second L-plate 52 are interlocked with each other. When the abutment block 421 moves in a direction away from the clamping block 41, the first L-plate 51 moves with the abutment block 421 and abuts against one end of the corresponding second L-plate 52 away from the clamping block 41, and the clamping block 41 is driven to move in a direction away from the center of the clamping block 41 through the second L-plate 52.

[0044] With such a design, when the culture container 8 finishes shaking, the lead screw 412 is reversed, and the two moving blocks 423 on each adjusting member 42 drive the corresponding two limit blocks 4221 to move away from each other. At this time, the limit block 4221 leaves the outer wall of the clamping block 41, and the first L-plate 51 moves along with the corresponding limit block 4221 and abuts against the end of the second L-plate 52 away from the clamping block 41. As the limit block 4221 continues to move, each first L-plate 51 drives the two clamping blocks 41 to move away from each other through the corresponding second L-plate 52. At this time, the adjusting member 42 is reset and no longer clamps the culture container 8.

[0045] In one embodiment, a circular groove 11 is provided on the constant temperature platform 1;

[0046] The shaking component 3 includes a power unit 31 arranged in the constant temperature table 1, the output shaft of the power unit 31 passes through the circular groove 11 of the constant temperature table 1 and is connected to a rotating disk 32, and the rotating disk 32 is arranged in the circular groove 11, and a connecting rod 321 is provided at the eccentric point of the rotating disk 32, and the other end of the connecting rod 321 is flush with the top of the constant temperature table 1 and connected to the support 2. When the rotating disk 32 rotates, the rotating disk 32 drives the support 2 to move in a circle on the constant temperature table 1 with the center of the rotating disk 32 as the midpoint through the connecting rod 321.

[0047] With such a design, after each culture container 8 is clamped and fixed by the clamping component 4, the power unit 31 is started, and the power unit 31 drives the rotating disk 32 to rotate. The rotating disk 32 drives the support 2 to move in a circle on the constant temperature table 1 with the center of the rotating disk 32 as the midpoint through the connecting rod 321, thereby shaking each culture container 8.

[0048] Preferably, the power unit 31 can adopt a motor in the prior art.

[0049] In one embodiment, a lining 6 is provided on one side of the clamping block 41 close to the culture container 8, and when the clamping block 41 clamps the culture container 8, the lining 6 is used to protect the culture container 8. With this design, since the culture container 8 is mostly made of glass, when the clamping component 4 is working, the clamping block 41 with a larger clamping specification will abut and clamp the culture container 8 for many times as the lead screw 412 rotates, and finally provide a clamping force to the culture container 8. The lining 6 is provided to prevent the clamping block 41 from damaging the outer wall of the culture container 8 during the working process.

[0050] In one embodiment, the constant temperature platform 1 is provided with a protective cover 7, which is arranged around the support 2 and is used to isolate the working environment of cell culture from the external environment. The protective cover 7 is rotatably provided with an observation window 71, which is convenient for the staff to observe the cultured cells. With this design, the setting of the protective cover 7 can protect the culture container 8 from the influence of changes in the external environment during the shaking process, and it is convenient for the staff to observe the state of the culture container 8 at all times.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
