Description

Technical Field

[0001] This utility model relates to the field of cell culture dish technology, specifically to a cell culture dish that facilitates separation. Background Technology

[0002] A culture dish is a laboratory vessel used for culturing microorganisms or cells. It consists of a flat, disc-shaped base and a lid, and is generally made of plastic. Culture dishes are basically divided into two categories: plastic and glass. When a large number of cells need to be cultured, a large number of cell culture dishes are usually used, so it is necessary to place a large number of cell culture dishes together.

[0003] A search revealed a patent, CN222948349U, which discloses a cell culture dish for easy separation. The dish includes a main body with a lid, two sets of culture tubes inside, a support plate fixedly mounted inside, two grooves inside the main body, and two threaded grooves inside the support plate. Fixing sleeves are fixedly mounted on the outer surfaces of both sets of culture tubes. This easily separable cell culture dish, by providing fixing sleeves on the surface of the culture tubes, with the sleeves threaded into the threaded grooves, provides a stable fixation method, ensuring the culture tubes are firmly fixed within the dish, reducing the risk of displacement due to accidental collisions or movement. Furthermore, the auxiliary components further enhance the stability of cell culture and reduce the impact of external factors on cell growth.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned prior art documents describe a method of connecting multiple cell culture tubes to a culture dish using threaded connections. Due to the large number of culture tubes, each tube requires multiple rotations for placement and removal, which is cumbersome and makes it difficult to separate the cell culture dish. Therefore, there is an urgent need in the art to improve the cell culture dish in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a cell culture dish that is easy to separate, making it convenient to place and remove the placement tank.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cell culture dish that is easy to separate, comprising a culture dish body, an openable and closable lid on the upper part of the culture dish body, a plurality of placement slots on the upper part of the culture dish body for placing cell culture tubes, a plurality of elastic clamping plates in the placement slots, a relief groove adapted to the plurality of clamping plates on the inner side wall of the placement slots, a plurality of movable insertion posts having one end inserted into the inner side wall of the relief groove fixedly installed on one side of the clamping plates, and an elastic element sleeved on the side of the insertion post.

[0008] Preferably, a movable plate is fixedly installed on one side of the clamping plate, and a clearance hole adapted to the movable plate is opened on the inner side wall of the clearance groove. Movable grooves are opened on both the upper and lower side walls of the clearance groove. A triangular extrusion wedge block that penetrates the movable plate is movably connected in the movable groove. Extrusion ports adapted to the extrusion wedge block are opened through the upper and lower sides of the movable plate. A movable column extending to the top of the petri dish body is fixedly installed on the upper part of the extrusion wedge block.

[0009] Preferably, a pressing ring is fixedly installed between several movable columns extending to the upper end of the culture dish body, and the inner diameter of the pressing ring is larger than the inner diameter of the placement groove.

[0010] Preferably, the movable groove extends through the upper part of the culture dish body, and the upper part of the culture dish body is fixedly installed with a mounting cover plate sleeved on the side of the movable column by fasteners.

[0011] Preferably, a number of elastic compression plates adapted to the placement groove are fixedly installed on the inner wall of the lid, and the side of the elastic compression plate near the placement groove is elastic.

[0012] Preferably, both the lid and the elastic compression plate have through-holes for observation, and a transparent plate is provided inside the observation holes.

[0013] Preferably, an arc-shaped and elastic protrusion is fixedly installed on one side of each opposite side of the petri dish body, and a snap-fit ​​groove adapted to the elastic protrusion is provided on the opposite side wall of the inner wall of the dish lid.

[0014] To address the shortcomings of existing technologies, this invention provides a cell culture dish that facilitates cell separation, overcoming the deficiencies of the prior art. The beneficial effects of this invention are as follows:

[0015] In this invention, the cell culture tube is inserted downwards by means of the cooperation of the clamping plate, the elastic element and the plug post. Several clamping plates clamp and fix the cell culture tube, which is faster and more convenient than the threaded connection method, and makes it easier to place and remove the placement slot.

[0016] In this invention, by setting up a squeezing wedge block, a movable plate, a moving column, and a pressing ring, pressing down on the pressing ring drives several clamping plates to move simultaneously in opposite directions, placing the cell culture tube in the placement groove. After the cell culture tube is completely placed in the placement groove, the pressing ring is released, and the tension of the elastic element pushes the clamping plates to clamp and fix the cell culture tube, making it more convenient to place or remove the cell culture tube. Moreover, no force needs to be applied to the cell culture tube when placing or removing it, ensuring the stability of the cell culture tube during placement or removal.

[0017] In this invention, the elastic protrusion strip, the snap-fit ​​groove, and the elastic compression plate work together to provide a certain sealing and limiting effect on the upper end of the cell culture tube, thereby improving the stability of the cell culture tube.

[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-8 A cell culture dish that facilitates separation includes a culture dish body 1, a closable lid 2 on the upper part of the culture dish body 1, several placement slots 3 on the upper part of the culture dish body 1 for placing cell culture tubes 4, several elastic clamping plates 5 inside the placement slots 3, and relief slots 6 on the inner side wall of the placement slots 3 that are adapted to the clamping plates 5. Several movable insertion posts 7 are fixedly installed on one side of the clamping plates 5, with one end inserted into the inner side wall of the relief slot 6. Elastic members 8 are sleeved on the side of the insertion posts 7.

[0032] In this embodiment, the specific implementation method is as follows: When it is necessary to use a culture dish to culture cells, the cells to be cultured are placed in the cell culture tube 4, and the cell culture tube 4 is inserted into the placement groove 3. The upper part of the clamping plate 5 has an oblique angle for guidance. The side of the cell culture tube 4 is squeezed against several clamping plates 5, and the clamping plates 5 move accordingly. One end of the insertion post 7 moves in the inner wall of the relief groove 6. The elastic element 8 is compressed and generates a reaction force. The elastic element 8 is specifically a spring. The cell culture tube 4 is inserted downward with force, and several clamping plates 5 clamp and fix the cell culture tube 4. Compared with the threaded connection method, it is faster and more convenient to place and remove the placement groove 3. After several cell culture tubes 4 are placed, the dish lid 2 is closed.

[0033] Example 2

[0034] Please see Figure 4 , Figure 5 , Figure 6 and Figure 8This embodiment includes the above embodiment, and further includes: a movable plate 9 is fixedly installed on one side of the clamping plate 5; a clearance hole 14 adapted to the movable plate 9 is opened on the inner side wall of the clearance groove 6; movable grooves 12 are opened on the upper and lower side walls of the clearance groove 6; a triangular extrusion wedge block 10 that penetrates the movable plate 9 is movably connected in the movable groove 12; extrusion ports 11 adapted to the extrusion wedge block 10 are opened through the upper and lower sides of the movable plate 9; a movable column 13 extending to the upper part of the culture dish body 1 is fixedly installed on the upper part of the extrusion wedge block 10; a pressing ring 15 is fixedly installed between the upper ends of several movable columns 13 extending to the upper part of the culture dish body 1; the inner diameter of the pressing ring 15 is larger than the inner diameter of the placement groove 3; the movable groove 12 penetrates the upper part of the culture dish body 1; and an installation cover plate 16 sleeved on the side of the movable column 13 is fixedly installed on the upper part of the culture dish body 1 by fasteners.

[0035] In this embodiment, the specific implementation is as follows: When it is necessary to place or remove the cell culture tube 4, the pressing ring 15 is pressed down, causing the moving column 13 to move downward. The moving column 13 then causes the squeezing wedge block 10 to move downward within the movable groove 12. One side of the squeezing wedge block 10 is inclined. When the squeezing wedge block 10 moves downward, its inclined surface squeezes the movable plate 9 towards the clearance hole 14, thereby causing several clamping plates 5 to move simultaneously in opposite directions. At this time, the cell culture tube 4 is placed in the placement groove 3. After the cell culture tube 4 is completely placed in the placement groove 3, the pressing ring 15 is released. The tension of the elastic element 8 pushes the clamping plate 5 to clamp and fix the cell culture tube 4. At the same time, the movable plate 9 moves and pushes the squeezing wedge block 10 upward. Through the above settings, it is more convenient to place the cell culture tube 4. The cell culture tube 4 is placed or removed without applying force, ensuring stability during placement and removal. The cover plate 16 is fixedly installed at the upper opening of the movable groove 12 with fasteners. When assembling the whole device, the elastic element 8 is sleeved on the side of the insertion post 7, and one end of the two insertion posts 7 is inserted into the inner wall of the relief groove 6. The position of the extrusion port 11 is aligned with the position of the movable groove 12, and the extrusion wedge block 10 is inserted into the movable groove 12 and passes through the extrusion port 11. Then, the cover plate 16 is sleeved on the side of the moving column 13 and fixedly installed on the upper part of the culture dish body 1 with fasteners. Then, the pressure ring 15 is fixedly installed on the upper part of several moving columns 13 with fasteners, which facilitates the assembly of the whole device.

[0036] Example 3

[0037] Please see Figures 1-4 and Figure 7This embodiment includes all the above embodiments, and further includes: a plurality of elastic compression plates 17 adapted to the placement groove 3 are fixedly installed on the inner side wall of the dish cover 2. The side of the elastic compression plate 17 near the placement groove 3 is elastic. An observation port 18 is provided through the dish cover 2 and the elastic compression plate 17. A transparent plate is provided in the observation port 18. An elastic protrusion strip 19 with an arc shape and elasticity is fixedly installed on the opposite side of the culture dish body 1. A snap-fit ​​groove 20 adapted to the elastic protrusion strip 19 is provided on the opposite side wall of the inner side of the dish cover 2.

[0038] In this embodiment, after several cell culture tubes 4 are placed, the dish lid 2 is aligned with the culture dish body 1 and pushed towards the culture dish body 1 until the elastic protrusion 19 is engaged in the engagement groove 20. Since the lower part of the elastic compression plate 17 is elastic, it provides a certain sealing and limiting effect on the upper end of the cell culture tube 4, thereby improving the stability of the cell culture tube 4. Furthermore, the transparent plate fixedly installed in the observation port 18 allows for real-time observation of the inside of the cell culture tube 4. The transparent plate can be made of acrylic or glass, etc.
