Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell culture dish technology, specifically to a stable stacked cell culture dish. Background Technology
[0002] A cell culture dish is a laboratory vessel used for culturing microorganisms or cells. Its main components include a transparent saucer and a matching lid. The saucer holds the culture medium and provides a stable base. The lid protects the medium from contamination and reduces moisture evaporation; it is also transparent to allow observation of the sample inside the dish. Cell culture dishes have wide applications in microbiology and cell biology research.
[0003] Currently, traditional cell culture dishes are usually placed directly on the lab bench. Placing multiple cell culture dishes flat on the lab bench takes up a lot of space and affects other operations on the lab bench. If cell culture dishes are stacked on the lab bench, their smooth surfaces can easily cause them to tip over and fall, making it impossible to guarantee the safe use of the cell culture dishes. Therefore, we have proposed a stable stacking cell culture dish to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide a stable stackable cell culture dish to solve the problem mentioned in the background art that current cell culture dishes are inconvenient to stack.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable stacked cell culture dish, comprising a culture dish body and a dish body cover, wherein the dish body cover is installed on the culture dish body, a first magnetic ring is fixed on the outer side of the upper end of the dish body cover, a connecting sleeve is installed on the outer side of the culture dish body, a protective cover is provided on the outer side of the connecting sleeve, a spring piece is fixed between the protective cover and the connecting sleeve, and a limit ring is installed at the bottom of the culture dish body.
[0006] Preferably, the culture dish body and the dish body cap are threaded together.
[0007] Preferably, a slot is provided on the outer side of the culture dish, and a block is fixed on the inner side of the connecting sleeve. The block inside the connecting sleeve is embedded in the slot outside the culture dish.
[0008] Preferably, the inner diameter of the connecting sleeve is equal to the outer diameter of the culture dish body, and the connecting sleeve forms an up-and-down movable structure on the culture dish body.
[0009] Preferably, the lower outer side of the culture dish body is provided with external threads, the limiting ring is provided with internal threads, and the limiting ring and the culture dish body are detachably connected.
[0010] Preferably, the outer diameter of the limiting ring is larger than the outer diameter of the culture dish.
[0011] Preferably, the protective cover forms a fixed structure between the spring piece and the connecting sleeve, and the protective cover forms an up-and-down moving structure on the culture dish body through the connecting sleeve. When the connecting sleeve moves to the lowest point below the culture dish body, the protective cover protrudes from the outer side of the lower end of the culture dish body.
[0012] Preferably, a second magnetic ring is fixed to the inner side of the lower end of the protective cover, and the inner diameter of the protective cover is equal to the outer diameter of the dish cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) The cell culture dish is equipped with a protective cover that can be raised and lowered. When the culture dishes are stacked together, the protective cover is lowered so that it covers the cover of the lower culture dish. This ensures that the cell culture dishes can be mutually restrained after being stacked together, and ensures that the stacking state is stable.
[0015] (2) At the same time, a first magnetic ring is provided on the outside of the dish cover and a second magnetic ring is provided inside the protective cover. When the protective cover is placed on the dish cover, the first magnetic ring and the second magnetic ring attract each other, which can further strengthen the stability of the connection between the protective cover and the dish cover, thereby enhancing the safety of the stacked state of the cell culture dish.
[0016] (3) A spring and a connecting sleeve are provided inside the protective cover. The spring makes the protective cover have a buffer and anti-collision effect, and the connecting sleeve is connected to the culture dish body through the slot and the block. This ensures the stable working state of the protective cover and effectively avoids external factors from directly colliding with the culture dish body, thus enhancing the safety of the culture dish body.

[0026] The technical solutions of the present utility model 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 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.
[0027] Please see Figure 1-8 This utility model provides a technical solution: a stable stacked cell culture dish, including a culture dish body 1 and a dish cover 2, wherein the dish cover 2 is installed on the culture dish body 1, and a first magnetic ring 3 is fixed on the outer side of the upper end of the dish cover 2.
[0028] Furthermore, the petri dish body 1 and the dish cover 2 are threaded together to ensure a stable connection between them.
[0029] A connecting sleeve 6 is installed on the outside of the petri dish body 1, and a protective cover 4 is provided on the outside of the connecting sleeve 6. A spring piece 5 is fixed between the protective cover 4 and the connecting sleeve 6.
[0030] Furthermore, a slot 9 is provided on the outer side of the culture dish body 1, and a locking block 12 is fixed on the inner side of the connecting sleeve 6. The locking block 12 inside the connecting sleeve 6 is embedded in the slot 9 outside the culture dish body 1. The inner diameter of the connecting sleeve 6 is equal to the outer diameter of the culture dish body 1, and the connecting sleeve 6 forms an up-and-down moving structure on the culture dish body 1, so that the connecting sleeve 6 can only move up and down on the culture dish body 1 and cannot rotate, ensuring the stable working state of the protective cover 4.
[0031] Furthermore, the protective cover 4 forms a fixed structure with the spring piece 5 and the connecting sleeve 6, and the protective cover 4 forms an up-and-down moving structure on the culture dish body 1 through the connecting sleeve 6, which can ensure the stable working state of the protective cover 4, thereby achieving the protective effect on the culture dish body 1.
[0032] Furthermore, when the connecting sleeve 6 moves to the lowest point below the culture dish body 1, the protective cover 4 protrudes from the outer side of the lower end of the culture dish body 1. The inner diameter of the protective cover 4 is equal to the outer diameter of the dish cover 2, ensuring that the protective cover 4 can be properly fitted onto the dish cover 2 below when the culture dishes are stacked, thereby enhancing the stability of the stacked culture dishes.
[0033] Furthermore, a second magnetic ring 8 is fixed to the inner side of the lower end of the protective cover 4. When the culture dishes are stacked, the second magnetic ring 8 on the protective cover 4 and the first magnetic ring 3 on the lower cover 2 are magnetically attracted to each other, further enhancing the stability of the stacked culture dishes.
[0034] A limiting ring 7 is installed at the bottom of the culture dish body 1. The lower outer side of the culture dish body 1 is provided with an external thread 10, and the limiting ring 7 is provided with an internal thread 11. The limiting ring 7 and the culture dish body 1 are detachably connected. The outer diameter of the limiting ring 7 is larger than the outer diameter of the culture dish body 1, so that the protective cover 4, the spring piece 5 and the connecting sleeve 6 can be directly removed from the culture dish body 1 through the removal of the limiting ring 7, so as to facilitate the cleaning of the culture dish and ensure that the culture dish can be reused normally.
[0035] Working principle: When using this cell culture dish, first rotate the dish lid 2 to open the culture dish 1, put the culture medium in the culture dish 1, plant the cells to be cultured in the culture medium, and then close the dish lid 2 to ensure that the cell culture in the cell culture dish proceeds normally.
[0036] Place the cell culture dish in use on the experimental table. If there are other cell culture dishes later, they can be placed directly on the previous cell culture dish. When the cell culture dishes are stacked together, the protective cover 4 on the upper cell culture dish can be moved downward so that the lower end of the protective cover 4 can cover the dish cover 2 on the lower cell culture dish. In this way, the upper and lower cell culture dishes can be connected together, effectively preventing the cell culture dishes stacked together from falling off due to misalignment, and ensuring the stability and safety of the stacked cell culture dishes.
[0037] When cell culture dishes are stacked, the upper protective cover 4 and the lower dish cover 2 are magnetically connected by the first magnetic ring 3 and the second magnetic ring 8, which further strengthens the stability of the connection between the protective cover 4 and the dish cover 2, so that even if the stacked cell culture dishes are tilted as a whole, they are not easy to separate.
[0038] In subsequent use of this cell culture dish, if it is necessary to remove it for observation, you can hold the protective cover 4 and move it upwards. This will allow the upper and lower cell culture dishes to be separated directly, making it convenient to remove the corresponding cell culture dishes for observation.
[0039] When observing the cell culture dish, the protective cover 4 is fixed to the connecting sleeve 6 by the spring piece 5, and the connecting sleeve 6 is moved and limited on the culture dish body 1 by the slot 9 and the locking block 12. Therefore, the cell culture dish can be picked up and observed by holding the protective cover 4. In addition, the protective cover 4 has a certain buffering effect through the spring piece 5, so the safety of using the cell culture dish on the experimental table can also be enhanced.
[0040] After the cell culture dish is used up, the limiting ring 7 at the bottom of the culture dish body 1 can be removed to release the position limitation of the connecting sleeve 6. Then the protective cover 4 and the connecting sleeve 6 can be removed from the culture dish body 1 to facilitate a thorough cleaning of the cell culture dish and ensure safe reuse.
[0041] The above describes the process of using this cell culture dish. Any content not described in detail in this manual is existing technology known to those skilled in the art.
[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
