Description

Technical Field

[0001] This utility model relates to the field of biological culture technology, and in particular to a cell culture box. Background Technology

[0002] Cell culture incubators are commonly used devices in medicine and biology, providing a stable and controllable growth environment for cells.

[0003] In existing neutralizing antibody experiments, sample cells need to be digested with trypsin to form a cell suspension, which is then placed in a culture dish and incubated in an incubator. However, due to the limited space on the culture plate racks and the limited internal space of the cell culture incubator, it is inconvenient for staff to retrieve culture dishes stored further back in the incubator. Therefore, this application proposes a cell culture incubator that allows for convenient retrieval of culture dishes from any location within the incubator. Utility Model Content

[0004] The main objective of this invention is to provide a cell culture box that allows for easy access to culture dishes at any point within the cell culture box.

[0005] To achieve the above objectives, this utility model provides a cell culture incubator, comprising:

[0006] The box body is equipped with a rotating door;

[0007] Multiple placement components are vertically distributed within the box. Each placement component includes a detachable culture rack disposed within the box. The culture rack has multiple through holes for air circulation. A placement plate is rotatably mounted on the culture rack. The placement plate also has multiple through holes for air circulation. The placement plate is used to hold the culture dish.

[0008] Furthermore, multiple limiting components are vertically distributed inside the box. Each limiting component includes two mounting slots on the corresponding sidewalls of the inner cavity of the box. Each mounting slot is U-shaped and closed at the end away from the box door. The two mounting slots are arranged opposite each other, and the two sides of the corresponding culture rack are slidably disposed in the corresponding mounting slots. The mounting slots are used to restrict the movement of the corresponding culture rack. Each mounting slot is also provided with a limiting member at the end near the box door. The limiting member is used to restrict the corresponding culture rack from moving towards the end near the box door.

[0009] Furthermore, the limiting component includes a rotating rod rotatably mounted on the top surface of the end of the mounting groove near the door. The rotating rod is L-shaped and has a protrusion at the top of its vertical end. The vertical end of the rotating rod is in contact with the end of the mounting groove near the door. A torsion spring is provided at the rotatable connection between the rotating rod and the mounting groove. The torsion spring is used to drive the rotating rod to rotate upward. A buckle is also provided at the bottom of the end of the mounting groove near the door. When the rotating rod rotates downward, the buckle is used to lock the protrusion on the rotating rod.

[0010] Furthermore, each of the mounting slots is vertically slidably disposed on the corresponding side wall inside the box, and a chamber is formed inside the top of the box;

[0011] The housing is equipped with an adjustment component, which includes a first lead screw vertically rotatably mounted next to one side wall of the housing cavity. The top end of the first lead screw is rotatably inserted into the cavity, and multiple sets of first thread groups are vertically distributed on the first lead screw. Each first thread group consists of two thread segments with opposite directions of rotation. The mounting slots on the corresponding side of the housing correspond one-to-one with each thread segment on the first lead screw and are screwed into each other. When the first lead screw rotates, it drives the two mounting slots screwed into the same set of first thread groups to move closer or further apart. The top surface of the housing is also equipped with a power source. The unit has a moving end connected to the first lead screw. A second lead screw is rotatably mounted inside the housing. The second lead screw is positioned opposite to the first lead screw, and its top end is rotatably inserted into the cavity. The second lead screw has vertically distributed second thread groups that correspond one-to-one with each of the first thread groups on the first lead screw. Each mounting groove on the other side of the housing corresponds one-to-one with and engages with each thread segment on the corresponding second thread group. The cavity is also equipped with a belt drive assembly, and the power unit drives the first lead screw and the second lead screw to rotate synchronously through the belt drive assembly.

[0012] Furthermore, each of the placement trays has multiple limiting plates evenly distributed on it, and there is space between each limiting plate and the adjacent limiting plates for placing the culture dish. The limiting plates are used to constrain the movement of the culture dish.

[0013] Furthermore, a power supply is installed at the top of the box, and a main light strip for providing illumination is provided on the top surface of the inner cavity of the box. The main light strip is connected to the power supply, and one end of it is vertically arranged on the inner cavity of the box away from the box door. Multiple sub-light strips are also connected to the vertical end of the main light strip. Each sub-light strip is arranged on the inner cavity of the box and is distributed sequentially between each adjacent culture rack. The power supply is used to provide lighting power to the main light strip and each sub-light strip.

[0014] Furthermore, a groove is provided on the door;

[0015] The box is equipped with a transparent observation window that rotates on its surface. The observation window is located in the groove and rotates coaxially with the box door. The design of the observation window makes it convenient for staff to observe the experimental conditions of the culture dishes inside the box.

[0016] The beneficial effects of this utility model are reflected in:

[0017] This invention, through the cooperation of each culture rack and corresponding placement tray, allows staff to easily retrieve culture dishes from inconvenient locations on the placement tray when they need to take them out. They simply need to rotate the placement tray to change the relative position between the corresponding culture dish and the door, thus making it convenient to take out culture dishes from any location on the placement tray.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0027] See Figures 1-6 .

[0028] This utility model discloses a cell culture incubator, comprising:

[0029] Box 1, which is equipped with a rotating door 11;

[0030] Multiple placement components 2 are vertically distributed at equal intervals in the inner cavity of the box body 1. Each placement component 2 includes a detachable culture rack 21 disposed in the box body 1. The culture rack 21 has multiple through holes (not shown in the figure) for air circulation. A placement plate 22 is rotatably mounted on the culture rack 21. The placement plate 22 also has multiple through holes (not shown in the figure) for air circulation. The placement plate 22 is used to hold the culture dish.

[0031] In practice, staff place the culture dishes to be tested on each placement tray 22 and place each culture rack 21 inside the box 1 to culture the cells in the culture dishes. When staff need to take out the culture dish placed on the placement tray 22 away from the box door 11, they rotate the corresponding placement tray 22. The placement tray 22 drives the corresponding culture dish to rotate, thereby changing the relative position between the corresponding culture dish and the box door 11, making it easier for staff to take out the culture dish.

[0032] In this invention, each culture rack 21 cooperates with the corresponding placement tray 22. When staff need to retrieve a culture dish that is inconvenient to remove from the placement tray 22, they only need to rotate the placement tray 22 to change the relative position between the corresponding culture dish and the door 11, thereby making it convenient to retrieve any culture dish on the placement tray 22.

[0033] In one embodiment, a plurality of limiting components 3 are vertically distributed inside the box body 1. Each limiting component 3 includes two mounting grooves 31 disposed on the corresponding side walls of the inner cavity of the box body 1. Each mounting groove 31 is U-shaped and closed at one end away from the box door 11. The two mounting grooves 31 are disposed opposite to each other. The two sides of the corresponding culture rack 21 are respectively slidably disposed in the corresponding mounting groove 31. The mounting groove 31 is used to restrict the movement of the corresponding culture rack 21. Each mounting groove 31 is also provided with a limiting member 32 at the end near the box door 11. The limiting member 32 is used to restrict the corresponding culture rack 21 from moving towards the end near the box door 11.

[0034] With this design, when the culture rack 21 needs to be placed inside the box 1, the two sides of the corresponding culture rack 21 are slidably set into the corresponding mounting slots 31, and the end of the culture rack 21 away from the box door 11 is in contact with the closed end of the corresponding mounting slot 31. At this time, the mounting slot 31 restricts the corresponding culture rack 21 from moving in the direction away from the box door 11 and in the vertical direction. This prevents the staff from accidentally shaking the culture rack 21 during work, which could cause the culture dishes on the corresponding culture rack 21 to move or even tip over, thus affecting the experimental data.

[0035] In one embodiment, the limiting member 32 includes a rotating rod 321 rotatably disposed on the top surface of the end of the corresponding mounting groove 31 near the door 11. The rotating rod 321 is L-shaped and has a protrusion 322 on the top of its vertical end. The vertical end of the rotating rod 321 is in contact with the end of the corresponding mounting groove 31 near the door 11. A torsion spring (not shown in the figure) is provided at the rotatable connection between the rotating rod 321 and the mounting groove 31. The torsion spring is used to drive the rotating rod 321 to rotate upward. A buckle 323 is also provided at the bottom of the end of the mounting groove 31 near the door 11. When the rotating rod 321 rotates downward, the buckle 323 is used to lock the protrusion 322 on the corresponding rotating rod 321.

[0036] With this design, when the culture rack 21 is placed in the corresponding mounting slot 31, the corresponding rotating rod 321 is rotated downwards, causing the protrusions 322 on each rotating rod 321 to engage in the latches 323. At this time, the torsion springs are compressed, and the vertical ends of each rotating rod 321 are attached to the side of the corresponding mounting slot 31 near the door 11, sealing the opening of the mounting slot 31. At this time, the rotating rod 321 is used to restrict the corresponding culture rack 21 from moving towards the end near the door 11. At this moment, the culture rack 21 cannot move within the corresponding mounting slot 31. When it is necessary to remove the culture rack 21, the corresponding rotating rod 321 is rotated upwards, causing the protrusions 322 on each rotating rod 321 to disengage from the corresponding latches 323. At this time, the torsion springs are unrestrained and drive the corresponding rotating rods 321 to rotate upwards, releasing the restriction on the culture rack 21 moving towards the door 11.

[0037] It should be noted that the buckle 323 is arc-shaped and has a certain degree of elasticity. When the protrusion 322 rotates downward toward the center of the corresponding culture rack 21, the protrusion 322 contacts the opening of the corresponding buckle 323 and expands the opening of the buckle 323 until the protrusion 322 enters the corresponding buckle 323. At this time, the buckle 323 restores its deformation due to its elasticity and holds the corresponding protrusion 322.

[0038] It should be noted that the clamping force of the buckle 323 is greater than the torque of the corresponding torsion spring, thereby ensuring that the buckle 323 can properly limit the rotation rod 321 without being affected by external forces.

[0039] In one embodiment, each mounting slot 31 is vertically slidably disposed on the corresponding side wall inside the housing 1, and a chamber 12 is provided inside the top of the housing 1;

[0040] The housing 1 is equipped with an adjustment component 4, which includes a first lead screw 41 vertically rotatably mounted next to one side wall of the inner cavity of the housing 1. The top end of the first lead screw 41 is rotatably inserted into the chamber 12, and multiple sets of first thread groups 411 are vertically distributed on the first lead screw 41. Each first thread group 411 consists of two threaded segments with opposite directions of rotation. The mounting groove 31 on the corresponding side of the housing 1 corresponds to and engages with each threaded segment on the first lead screw 41. When the first lead screw 41 rotates, it drives the two mounting grooves 31 engaged with the same set of first thread groups 411 to move closer or further apart. The top surface of the housing 1 is also equipped with a power unit 42. The moving end of the power unit 42 is connected to the first lead screw 41. A second lead screw 43 is also rotatably installed inside the housing 1. The second lead screw 43 is arranged opposite to the first lead screw 41, and the top end of the second lead screw 43 is rotatably inserted into the chamber 12. The second lead screw 43 has vertically distributed second thread groups 431 that correspond one-to-one with the first thread groups 411 on the first lead screw 41. The mounting slots 31 on the other side of the housing 1 correspond one-to-one with the thread segments on the corresponding second thread groups 431 and are screwed in. The chamber 12 is also provided with a belt drive assembly 44. The power unit 42 drives the first lead screw 41 and the second lead screw 43 to rotate synchronously through the belt drive assembly 44.

[0041] With this design, when the culture rack 21 needs to be removed, the power unit 42 controls the first lead screw 41 and the second lead screw 43 to rotate, thereby driving the culture rack 21 to be removed to move downward. At this time, the mounting grooves 31 screwed on the same set of threads move closer or further away from each other, thereby driving the corresponding two culture racks 21 to move closer or further away from each other. At this time, there is enough space above the culture rack 21 to be removed for the staff to remove the culture rack 21.

[0042] Preferably, the power unit 42 can be an electric motor from the prior art.

[0043] It should be noted that the belt drive assembly 44 includes two synchronous pulleys 441 respectively disposed on the moving end of the power unit 42 and the second lead screw 43, and a synchronous belt 442 connecting the two synchronous pulleys 441. When the power unit 42 drives the first lead screw 41 to rotate, the synchronous pulley 441 disposed on the power unit 42 drives the other synchronous pulley 441 on the second lead screw 43 to rotate through the synchronous belt 442, thereby realizing the synchronous rotation of the first lead screw 41 and the second lead screw 43.

[0044] In one embodiment, multiple limiting plates 221 are equidistantly distributed on each placement tray 22, and a space is left between each limiting plate 221 and the adjacent limiting plate 221 for placing the culture dish. The limiting plate 221 is used to constrain the movement of the culture dish.

[0045] With this design, each limiting plate 221 can help staff place the culture dishes more systematically, and when the placement tray 22 is rotated, the limiting plate 221 restricts the movement of the corresponding culture dish, thereby reducing the possibility of collisions between adjacent culture dishes.

[0046] In one embodiment, a power supply 5 is installed at the top of the box 1, and a main light strip 6 for providing illumination is provided on the top surface of the inner cavity of the box 1. The main light strip 6 is connected to the power supply 5, and one end of it is vertically installed inside the box 1, away from the box door 11. Multiple sub-light strips 61 are also connected to the vertical end of the main light strip 6. Each sub-light strip 61 is installed on the inner cavity of the box 1 and is distributed between each adjacent culture rack 21. The power supply 5 is used to provide lighting power to the main light strip 6 and each sub-light strip 61.

[0047] With this design, when the power supply 5 is powered on, the power supply 5 provides lighting conditions for the inside of the box 1 through the main light strip 6 and each sub-light strip 61, reducing blind spots in light and further providing a stable growth environment for the cells.

[0048] In one embodiment, the door 11 is provided with a groove 111;

[0049] The box 1 is equipped with a transparent observation window 13 that rotates on its own. The observation window 13 is located in the groove 111 and rotates coaxially with the box door 11. The design of the observation window 13 makes it convenient for staff to observe the experimental conditions of the petri dishes inside the box 1.

[0050] With this design, when staff need to observe the petri dishes, they only need to open the door 11 and observe the petri dishes inside the chamber 1 through the observation window 13, without exposing the inside of the chamber 1 to the external environment, thus avoiding contamination of the internal environment of the chamber 1.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, "multiple," "multiple groups," and "several" refer to two or more.
