[0057] The control unit 700 is used to control the operation of the electric hydraulic cylinder 500 and the protection unit 400 .

[0058] The storage unit 200 includes a lower placing component 201 and an upper placing component 202 for placing multiple experimental items. The upper placing component 202 is located above the lower placing component 201. The lower placing component 201 and the upper placing component 202 are connected by a long rod 203. Flipping drive components 204 are provided at both ends of the lower placing component 201 and the upper placing component 202. The flipping drive component 204 is used to assist in flipping the lower placing component 201 and the upper placing component 202.

[0059] Preferably, two long rods 203 are provided, and a parallelogram structure is formed between the two long rods 203 and the lower placement component 201 and the upper placement component 202, which has good stability; the two ends of the long rod 203 are hinged to the sides of the lower placement component 201 and the upper placement component 202 respectively.

[0060] Preferably, the flip driving assembly 204 can assist in achieving a 180° flip of the lower placement assembly 201 and the upper placement assembly 202 .

[0061] The protection unit 400 includes a driving motor 401 that drives a roller 402 to rotate. The roller 402 is connected to one end of the driving motor 401. A protective film 403 is connected to the roller 402. A counterweight bar 404 is provided at one end of the protective film 403. The counterweight bar 404 is used to lower the protective film 403 vertically.

[0062] Preferably, the material of the protective film 403 is rubber, which has good deformation ability and heat preservation effect; the driving motor 401 drives the roller 402 to retract and extend the protective film 403, and the counterweight bar 404 ensures that the protective film 403 is perpendicular to the horizontal plane.

[0063] The lower placement assembly 201 includes a storage member 201a, an outer frame 201b disposed outside the storage member 201a, a culture dish 201c for experimental reactions, a clamping member 201d for clamping the culture dish 201c, a sealing member 201e for preventing interference with the experimental reaction in the culture dish 201c, and flip gears 201f disposed at both ends of the outer frame 201b.

[0064] The specifications of the lower placement component 201 and the upper placement component 202 are the same, but the size of the flip gear 201f on the lower placement component 201 is larger than the size of the flip gear 201f on the upper placement component 202.

[0065] Preferably, the tooth width, tooth thickness, tooth pitch and tooth space width of the flip gear 201f of the lower placement component 201 and the upper placement component 202 are consistent, but the root circle diameter of the flip gear 201f on the lower placement component 201 is larger than the root circle diameter of the flip gear 201f on the upper placement component 202.

[0066] The flip driving assembly 204 includes a lower rack 204a, an upper rack 204b and a stop bar 204c for limiting displacement, and the upper rack 204b is placed above the lower rack 204a.

[0067] Preferably, the tooth heads of the lower rack 204a and the upper rack 204b are of the same size and spacing, but the number of teeth of the lower rack 204a is greater than the number of teeth of the upper rack 204b; wherein, the flip gear 201f of the upper placement component 202 is engaged with the upper rack 204b, and the flip gear 201f of the lower placement component 201 is engaged with the lower rack 204a; the lower rack 204a and the upper rack 204b can both keep the flip gear 201f engaged with them rotating one circle.

[0068] Preferably, after the flip gear 201f engaged with the upper rack 204b rotates one circle, the flip gear 201f will be blocked by the baffle 204c, so that the flip gear 201f cannot continue to move. However, under the same displacement distance, the flip gear 201f engaged with the lower rack 204a has not completed one circle of rotation, so it will continue to move an end distance, but the flip gear 201f engaged with the upper rack 204b cannot continue to move. Finally, the lower placement component 201 and the upper placement component 202 will be staggered by a certain distance, which is convenient for the staff to take and place the culture dish.

[0069] The storage component 201a includes a long plate 201a-1, a plurality of receiving grooves 201a-2 arranged on the long plate 201a-1 for placing culture dishes 201c, a card slot 201a-3 arranged at the edge of the receiving groove 201a-2, a card port 201a-4 located on the bottom surface of the card slot 201a-3, a button port 201a-5 located on one side of the card slot 201a-3, a connecting port 201a-7 for connecting one end of the sealing component 201e, the connecting port 201a-7 is placed at the edge of the receiving groove 201a-2, and the card slot 201a-3, the connecting port 201a-7 and the two chuck grooves 201a-6 are located at the four equal division points of the receiving groove 201a-2.

[0070] Preferably, there are multiple accommodating grooves 201a-2 on the long board 201a-1, and the reference figure shows four accommodating grooves 201a-2; the interior of the long board 201a-1 is hollow, and the hollow area is used to place a partial structure of the clamping member 201d, and each accommodating groove 201a-2 corresponds to a clamping member 201d.

[0071] The clamping member 201d includes a connecting post 201d-2, a clamping head 201d-1 for clamping a culture dish 201c, a torsion spring 201d-3 for resetting the clamping head 201d-1, a connector 201d-4 provided at one end of the connecting post 201d-2, the other end of the connecting post 201d-2 passing through the clamping head 201d-1 and connected to the torsion spring 201d-3, and used to connect the connector 201d-4 and the press button. The pull rope 201d-5 of the key 201d-6, the protrusion 201d-8 arranged on one side of the key 201d-6, the spring 201d-7 arranged on the bottom surface of the key 201d-6, the guide groove 201d-9 arranged on the inner side of the key 201d-6, one end of the guide rod 201d-10 is placed in the guide groove 201d-9, and the other end of the guide rod 201d-10 is hinged to the connecting block 201d-11.

[0072] Preferably, both ends of the connecting post 201d-2 are fixed to the chuck 201d-1 and the connecting head 201d-4, respectively; the chuck 201d-1 is placed in the chuck groove 201a-6, so that the connecting post 201d-2 passes through the inner wall of one side of the chuck groove 201a-6 and is connected to one side of the chuck 201d-1, and the other side of the chuck 201d-1 is hinged to the inner wall of the other side of the chuck groove 201a-6 via the torsion spring 201d-3;

[0073] Preferably, the chuck 201d-1 is V-shaped, refer to Figure 9When the chuck 201d-1 clamps the culture dish 201c and the seal 201e, the distance between the edges of the chuck 201d-1 at both ends and the axis of the culture dish 201c is smaller than the radius of the culture dish 201c. Therefore, the longitudinal displacement of the culture dish 201c and the seal 201e is limited, and the chuck 201d-1 remains stationary; when the chuck 201d-1 releases the culture dish 201c and the seal 201e, the seal 201e will be flipped due to the torsion springs at both ends of the flipping head 201e-2, and the two chucks 201d-1 will rotate 45° counterclockwise and clockwise respectively. At this time, the culture dish 201c will be lifted a short distance.

[0074] It should be noted that when the culture dish 201c is clamped, the upper port of the culture dish 201c is lower than the upper port of the receiving groove 201a-2; when the culture dish 201c is released, the upper port of the culture dish 201c is higher than the upper port of the receiving groove 201a-2.

[0075] The seal 201e includes an upper cover 201e-1 for sealing, a flip head 201e-2 is installed on the outer edge of the upper cover 201e-1, a pressing tongue 201e-3 is fixed on the other side of the upper cover 201e-1 that is symmetrical to the flip head 201e-2, and a hook 201e-4 is provided on the bottom surface of the pressing tongue 201e-3 to limit the movement of the upper cover 201e-1.

[0076] Preferably, the upper cover 201e-1 needs to be considered as being pressed onto the culture dish 201c. When the upper cover 201e-1 is pressed close to the culture dish 201c, the pressing tongue 201e-3 enters the card slot 201a-3. At this time, the hook 201e-4 is squeezed by the bayonet 201a-4 and deforms to a certain extent until the hook 201e-4 penetrates the bayonet 201a-4 and then recovers, and the hook 201e-4 hooks the edge of the bayonet 201a-4; at the same time, the lower end of the hook 201e-4 after penetrating the bayonet 201a-4 will squeeze the protrusion 201d-8.

[0077] Better, reference Figure 10 , the initial position of the guide rod 201d-10 is 5. When in use, the button 201d-6 is pressed, and the button 201d-6 moves downward. The spring 201d-7 is squeezed by the button 201d-6, and the guide rod 201d-10 begins to move from 5 to 1. When it reaches 6, the button 201d-6 is pressed to the lowest point, and then the spring 201d-7 rebounds, and the button 201d-6 moves upward. Since the corners in the self-locking groove are staggered, the self-locking rod 103 will not move back when it moves to the current position 6, but will continue to move toward 1. When it moves to position 1, the guide rod 201d-10 has already buckled the button 201d-6;

[0078] As the button 201d-6 moves upward, it pulls the drawstring 201d-5, which in turn pulls the connector 201d-4. The connecting post 201d-2 causes the chuck 201d-1 to deflect, releasing the culture dish 201c. Simultaneously, the protrusion 201d-8 squeezes the hook 201e-4, causing it to retract inward. The hook 201e-4 no longer hooks onto the edge of the bayonet 201a-4, and the seal 201e is automatically released without restraint.

[0079] When the staff has finished using the culture dish 201c and needs to cover the upper cover 201e-1, the lower end of the hook 201e-4 will squeeze the protrusion 201d-8, and the button 201d-6 will move downward. At this time, the guide rod 201d-10 starts to move from 1 to 4. Similarly, when the guide rod 201d-10 is in position 4, the button 201d-6 cannot continue to move downward. Finally, the guide rod 201d-10 will buckle the button 201d-6 at position 5. At this time, the chuck 201d-1 also clamps the culture dish 201c and the seal 201e.

[0080] During use, the control unit 700 starts to control the electric hydraulic cylinder 500 and the drive motor 401 to work simultaneously, the storage unit 200 is removed from the constant temperature box 300, and the protective film 403 is folded up; at this time, the lower placement component 201 and the upper placement component 202 are staggered, the culture dish 201c is flipped over, and the seal 201e is facing up; the staff selects the culture dish 201c to be opened according to the experimental requirements, and then presses the button 201d-6 corresponding to the culture dish 201c. At this time, the upper cover 201e-1 of the corresponding culture dish 201c will be opened; after completing the subsequent operation of the experimental sample, the staff closes the upper cover 201e-1 of the corresponding culture dish 201c, and the chuck 201d-1 will automatically clamp the culture dish 201c and the seal 201e, and finally controls the electric hydraulic cylinder 500 and the drive motor 401 through the control unit 700 to reset.

[0081] In summary, the device makes full use of the internal space of the constant temperature box 300. For the convenience of use, the culture dishes 201c on different layers will be staggered and displayed. At the same time, the culture dishes 201c will be turned from upside down to upright. At the same time, the device realizes the linkage between the release of the culture dish 201c and the opening of the upper cover 201e-1, and the clamping of the culture dish 201c and the closing of the upper cover 201e-1, which optimizes the staff's experimental operation of the culture dish 201c.
