Description

Technical Field

[0001] This invention belongs to the field of cell culture technology, and specifically relates to a stackable and stable cell culture dish. Background Technology

[0002] In the field of life science research, cell culture is a crucial basic experimental technique that is widely used in research and practice in multiple disciplines such as medicine, biology, and pharmacy. As a key instrument for cell culture, the rationality of the design and use of cell culture dishes directly affects the effect of cell culture. Traditional cell culture dishes usually consist of a flat disc-shaped base and a lid, and are mostly made of glass or plastic. This structure is simple and common.

[0003] When conducting microbial experiments or cell culture, cell culture dishes need to be placed in a specific environment to meet the conditions for cell growth. Placing them on a scaffold and inside a temperature-controlled device is a common method. However, existing scaffold structures have many drawbacks. On the one hand, existing scaffolds generally lack a structure to fix the cell culture dishes, which makes the cell culture dishes very easy to shake during scaffold movement. The shaking of the cell culture dishes may not only cause the culture medium to spill, resulting in waste of experimental materials and contamination of the experimental environment, but may also affect the cell growth environment due to uneven distribution of culture medium, thereby interfering with the accuracy of experimental results. On the other hand, existing scaffolds lack a stacking structure, making it difficult to stack them stably. This results in the space of the temperature-controlled device not being fully utilized, causing space waste and increasing experimental costs.

[0004] To improve cell culture conditions and increase experimental efficiency, many explorations and innovations have been carried out in related fields. For example, Chinese patent with announcement number "CN212504919U" discloses a multi-layer circular cell culture dish. This culture dish adopts a cylindrical body design with multiple culture surfaces inside the body. It has the characteristics of small size (10-15cm diameter) and is basically equivalent to several traditional single-layer culture dishes stacked together. To a certain extent, it reduces the space occupied by the incubator, makes the operation simpler, and has stronger sterility. It is easy to uniformly inoculate cells and completely harvest cells, and is suitable for small and medium-scale cell culture experiments.

[0005] However, this technology is not without its flaws. In practical use, it still has obvious shortcomings. The most prominent problem is the lack of a stable fixing structure. There is no effective restraint structure between the culture dishes. When the culture dishes are stacked high, the center of gravity rises, and the stability deteriorates. Or, if they are accidentally touched during stacking, the lack of restraint can easily cause relative displacement between the culture dishes, leading to the collapse of the entire stacked structure. This can not only damage the culture dishes and the cell samples inside, but may also lead to experimental failure, resulting in a waste of time and resources. It is evident that the above-mentioned existing technology is quite inconvenient to use, so it needs to be improved and designed. Utility Model Content

[0006] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a cell culture dish that can be stacked stably, so as to solve the problem of poor stacking stability of existing cell culture dishes.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A stackable and stable cell culture dish includes a base, with guide rails fixedly installed on both sides of the top of the base. A snap-fit ​​mechanism is slidably connected inside the guide rails, and a placement mechanism is fixedly installed between the inner sides of the snap-fit ​​mechanism. Guide rails are also fixedly installed on both sides of the top of the placement mechanism. Several sets of placement mechanisms are snapped and stacked on the top of the base through the snap-fit ​​mechanism.

[0009] The locking mechanism includes a sliding plate, a slot, and a limiting component. The sliding plate is slidably connected to the inside of the guide rail. The limiting component is fixedly installed on the rear side of the placement mechanism. The slot is opened on the rear side of the guide rail, and the end of the limiting component is inserted into the inside of the slot.

[0010] Furthermore, the placement mechanism includes a placement plate, which is fixedly installed on the inner side of the slide plate. A placement frame is fixedly installed on the top of the placement plate. The limiting component is fixedly connected to the rear side of the placement plate. Circular seats are fixedly connected to the top of the placement plate at equal intervals.

[0011] Furthermore, an annular groove is provided at the bottom of the circular seat, and a culture dish body is placed inside the circular seat. An anti-slip rubber ring is fixedly connected to the lower end of the outer surface of the culture dish body, and the anti-slip rubber ring fills the interior of the annular groove.

[0012] Furthermore, the limiting component includes a rail frame, which is fixedly connected to the back of the placement plate. Limiting springs are fixedly installed at both ends inside the rail frame, and a connecting arm is fixedly installed at the outer end of the limiting spring. A limiting arm is fixedly connected to the outer end of the connecting arm, and the outer end of the limiting arm is inserted into the inside of the slot.

[0013] Furthermore, an adjusting arm is fixedly connected to the bottom of the connecting arm, and a push plate is fixedly connected to the front end of the adjusting arm. The push plate is circular in shape.

[0014] Furthermore, the cross-sectional shape of the skateboard and the internal cross-sectional shape of the guide rail are both set to a convex shape, and the outer surface corners of the base, guide rail and skateboard are all set to an arc shape.

[0015] Furthermore, a magnetic suction plate is fixedly connected to the middle of the base, and anti-slip textures are provided at equal intervals on the bottom of the base.

[0016] In summary, the present invention has the following main advantages:

[0017] First, this device uses a snap-fit ​​mechanism and a limiting component to effectively improve the stability of stacked culture dishes. When in use, first insert the slide into the guide rail and install the placement mechanism. Because there is a guide rail on the top of the placement plate, it is convenient to stack multiple layers. When stacking, the limiting spring resets and pushes the connecting arm, so that the limiting snap arm is inserted into the slot, which stabilizes the stacked placement mechanism, effectively reduces the risk of culture dishes collapsing, and enhances the stability of the device during use.

[0018] Secondly, the placement mechanism of this device facilitates the handling and replacement of petri dishes and the replacement of the placement mechanism. When in use, the petri dish body is inserted into the round base, and the anti-slip rubber ring on its bottom is then locked in the annular groove of the round base, ensuring stable placement. When it is removed, it can be pulled out. When it is necessary to separate the placement mechanism, push the push plate to move the adjusting arm and connecting arm, so that the limiting arm is disengaged from the limiting groove, and the sliding plate can be pulled out for quick replacement of the placement mechanism, making it more convenient to use.

[0025] 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.

[0026] Example

[0027] Please refer to Figure 1-5 This embodiment of a stackable stable cell culture dish includes a base 1, with guide rails 2 fixedly installed on both sides of the top of the base 1. A snap-fit ​​mechanism 3 is slidably connected inside the guide rails 2. A placement mechanism 5 is fixedly installed between the inner sides of the snap-fit ​​mechanism 3. Guide rails 2 are also fixedly installed on both sides of the top of the placement mechanism 5. Several sets of placement mechanisms 5 are snapped and stacked on the top of the base 1 through the snap-fit ​​mechanism 3.

[0028] The locking mechanism 3 includes a sliding plate 31, a slot 32, and a limiting component 33. The sliding plate 31 is slidably connected to the inside of the guide rail 2, and the limiting component 33 is fixedly installed on the rear side of the placement mechanism 5. The slot 32 is opened on the rear side of the guide rail 2, and the end of the limiting component 33 is inserted into the inside of the slot 32. When using this type of stacked and stable cell culture dish, the base 1 provides support for the entire device. First, the sliding plate 31 of the locking mechanism 3 is slidably inserted along the guide rails 2 on both sides of the top of the base 1, so that the sliding plate 31 mates with the guide rail 2. After the sliding plate 31 is inserted into place, the placement mechanism 5 is installed between the inner sides of the locking mechanism 3. Since guide rails 2 are also installed on both sides of the top of the placement mechanism 5, it facilitates the subsequent stacking operation. When multiple sets of placement mechanisms 5 need to be stacked, the limiting component 33 of the snap-fit ​​mechanism 3 is used. The limiting component 33 is fixed to the rear side of the placement mechanism 5. When the placement mechanisms 5 are stacked, the end of the limiting component 33 will be inserted into the slot 32 opened on the rear side of the lower guide rail 2. Through this snap-fit ​​method, multiple sets of placement mechanisms 5 are stably stacked on the top of the base 1 to prevent displacement or collapse between the placement mechanisms 5, thereby achieving the stability of the cell culture dish stacking and meeting the requirements for stable placement of culture dishes during cell culture.

[0029] Please refer to Figures 1-5 The placement mechanism 5 includes a placement plate 51, which is fixedly installed inside the slide plate 31. A placement frame 52 is fixedly installed on the top of the placement plate 51. A limiting component 33 is fixedly connected to the rear side of the placement plate 51. Circular seats 53 are fixedly connected to the top of the placement plate 51 at equal intervals. An annular groove 54 is formed at the bottom of the circular seat 53. A culture dish body 55 is placed inside the circular seat 53. An anti-slip rubber ring 56 is fixedly connected to the lower end of the outer surface of the culture dish body 55, and the anti-slip rubber ring 56 fills the interior of the annular groove 54. In this cell culture dish device, the placement mechanism 5 plays a key role in placing and fixing the culture dish body 55. The placement plate 51 is fixedly installed inside the slide plate 31, and the position adjustment and stacking are achieved by means of the cooperation between the slide plate 31 and the guide rail 2. The placement frame 52 on top of the placement plate 51 provides auxiliary support and protection for the overall structure. The circular seats 53 evenly distributed on the top of the placement plate 51 are key components for placing the culture dish body 55. When the culture dish body 55 is placed in the circular seat 53, the anti-slip rubber ring 56 at the lower end of the outer surface of the culture dish body 55 will deform with the placement action. When the culture dish body 55 reaches the appropriate position, the anti-slip rubber ring 56 will fill the annular groove 54 at the bottom of the circular seat 53. The elasticity of the rubber ring and its tight fit with the annular groove 54 increase the friction, so that the culture dish body 55 is placed stably in the circular seat 53, avoiding shaking or displacement of the culture dish body 55 during the experimental operation, ensuring the stability of the cell culture environment, and providing a guarantee for the smooth progress of cell culture experiments.

[0030] Please refer to Figures 2-3The limiting component 33 includes a rail frame 331, which is fixedly connected to the back of the placement plate 51. Limiting springs 332 are fixedly installed at both ends inside the rail frame 331. A connecting arm 333 is fixedly installed at the outer end of the limiting spring 332. A limiting arm 334 is fixedly connected to the outer end of the connecting arm 333. The outer end of the limiting arm 334 is inserted into the slot 32. An adjusting arm 335 is fixedly connected to the bottom of the connecting arm 333. A push plate 336 is fixedly connected to the front end of the adjusting arm 335. The push plate 336 is circular. The cross-sectional shape of the sliding plate 31 is... The internal cross-sectional shape of the base 1 and guide rail 2 is set as a convex shape. The outer surface edges of the base 1, rail frame 331 and slide plate 31 are all set as arcs. A magnetic suction plate 4 is fixedly connected to the middle of the base 1. Anti-slip textures are provided at equal intervals on the bottom of the base 1. During use, when the placement mechanism 5 is stacked, the limiting spring 332 is in its natural state or in a state of compression recovery caused by the installation process, pushing the connecting arm 333 outward. The limiting arm 334 at the outer end of the connecting arm 333 moves outward accordingly and is precisely inserted into the slot 3 opened on the rear side of the lower rail frame 331. Within 2, the stacked placement mechanism 5 is firmly fixed, preventing displacement or slippage during use and ensuring the stability of the stacked cell culture dishes. To separate the stacked placement mechanism 5, simply push the circular push plate 336. The push plate 336 moves forward, driving the adjusting arm 335. The adjusting arm 335 pulls the bottom of the connecting arm 333, causing the connecting arm 333 to move inward, thereby causing the limiting arm 334 to disengage from the slot 32. At this point, the placement mechanism 5 can be easily separated. The convex cross-section design of the slide plate 31 and the guide rail 2 allows the slide plate 31 to be easily separated from the slot 32. The sliding of the base 1 on the guide rail 2 is smooth and stable, effectively preventing the slide plate 31 from coming off the guide rail 2. The rounded corners of the outer surfaces of the base 1, the rail frame 331 and the slide plate 31 greatly improve the safety of operation, preventing accidental injury to the operator and damage to other items. The magnetic plate 4 in the middle of the base 1 can attract some magnetic tools, making them easy to use during the experiment. The anti-slip textures set at equal intervals on the bottom of the base 1 increase the friction between the device and the placement surface, making the entire device more stable when placed and less prone to sliding.

[0031] Operating principle and advantages: This device is equipped with a snap-fit ​​mechanism 3 and a limiting component 33. In actual use, the slide plate 31 is first inserted into the guide rail 2 to ensure that the slide plate 31 and the guide rail 2 fit tightly. After the insertion is completed, the placement mechanism 5 can be installed between the inner sides of each guide rail 2. Since each placement plate 51 is equipped with a guide rail 2 on its top, the placement mechanism 5 can be stacked quickly and conveniently in multiple layers. During the stacking process, the limiting spring 332 will automatically reset, pushing the connecting arm 333 to drive the limiting snap-fit ​​arm 334 to move outward. The limiting snap-fit ​​arm 334 will accurately insert into the slot 32. Through the mutual snap-fit ​​limiting of the limiting snap-fit ​​arm 334 and the slot 32, the stacked placement mechanism 5 is stabilized. In this way, the stability of each culture dish body 55 is greatly enhanced when stacked during use, which can effectively reduce the risk of collapse and improve the overall application stability of the device during use.

[0032] This device, through the placement mechanism 5, allows the culture dish body 55 to be inserted into the inner side of the circular base 53 during use. The bottom of the circular base 53 has an annular groove 54. During installation, the anti-slip rubber ring 56 on the bottom of the culture dish deforms, allowing the culture dish body 55 to be stably placed within the circular base 53 on the placement frame 52. When the anti-slip rubber ring 56 contacts the annular groove 54, it resets and fills the groove, further securing the culture dish body 55 within the circular base 53. To remove the culture dish body 55, simply pull it out. This... During the overall use of this device, it is convenient to quickly pick up and put down the culture dish body 55, and it has strong stability when placed. In addition, when it is necessary to separate the placement mechanism 5, push the push plate 336, and the push plate 336 drives the adjusting arm 335 to move. The adjusting arm 335 then drives the connecting arm 333 to move inward. The movement of the connecting arm 333 will cause the limiting arm 334 to disengage from the limiting groove, realizing the separation of the connecting arm 333 from the limiting groove. At this time, the slide plate 31 can be easily pulled out from the inside of the guide rail 2, which facilitates the quick replacement of the placement mechanism 5, making the device more convenient to use.
