Description

Technical Field

[0001] This utility model relates to the field of petri dish technology, specifically to petri dishes for biological experiments. Background Technology

[0002] In biological and microbiological research, petri dishes are a common laboratory tool. They are usually made of transparent plastic or glass and are disc-shaped, consisting of a shallow "dish" and a slightly taller lid that fits together to prevent external contamination.

[0003] Existing petri dishes require the storage of microorganisms to be transferred to the laboratory during use. However, during this transfer, the petri dishes are prone to collisions with external objects, which can damage them and cause contamination or even leakage of the stored microorganisms. Furthermore, during long-term cultivation of microorganisms, if the nutrient solution inside the petri dish is depleted, the sealed petri dish needs to be opened quickly in a sterile environment and nutrient solution needs to be added. This process carries risks of increased petri dish contamination, changes in the internal environment, physical disturbances, and temperature fluctuations. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a culture dish for biological experiments. Through the combined design of a protective component and a locking component, the top cover can be quickly locked and fixed, preventing the top cover from becoming loose and causing contamination of the internal environment. At the same time, it provides a buffer protection effect for the culture dish. Through the design of the filling component, nutrient solution can be quickly added to the sealed culture dish, avoiding the risks associated with directly opening the culture dish to add nutrient solution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a culture dish for biological experiments, comprising:

[0006] The box body contains a petri dish inside, and the top of the petri dish is covered with a lid;

[0007] A locking assembly is provided between the upper cover and the box body to fix the upper cover;

[0008] A protective component is provided between the box body and the culture dish to reduce damage to the culture dish caused by external forces; and

[0009] The filling component provided on the top cover is used to add nutrient solution to the inside of the culture dish.

[0010] Furthermore, the protection component includes:

[0011] A buffer plate is connected to the bottom of the petri dish, and multiple buffer springs are connected to the bottom of the buffer plate and the inner wall of the bottom of the box.

[0012] An annular block is connected to the inner wall of the box. Multiple connecting springs are connected between the upper surface of the buffer plate and the lower surface of the annular block. A rubber ring is provided on the top of the annular block.

[0013] A first rubber block with a ring structure is disposed on the outside of the culture dish;

[0014] Multiple second rubber blocks are connected to the outside of the buffer plate.

[0015] Furthermore, the multiple connecting springs are evenly distributed in a ring array, and the multiple second rubber blocks are evenly distributed in a ring array. One side of the first rubber block is connected to the inner wall of the ring block, and one side of the second rubber block is connected to the inner wall of the box.

[0016] Furthermore, the engagement component includes:

[0017] Two slots are formed on the outer surface of the upper cover, and the two slots are symmetrically arranged;

[0018] Two symmetrically arranged movable slots are formed on the outer surface of the box. A movable rod is inserted inside the movable slot. One end of the movable rod extends into the slot and is provided with an inclined surface.

[0019] Furthermore, the box body has multiple limiting grooves that communicate with the moving groove inside. Each limiting groove has a limiting plate that is connected to the moving rod inside. A limiting spring is connected between the limiting plate and the limiting groove.

[0020] Furthermore, the dispensing component includes:

[0021] An injection tube connected to the upper cover;

[0022] A blocking groove is formed inside the upper cover, and the blocking groove communicates with the injection pipe;

[0023] A blocking block is disposed inside the blocking groove, and the cross-sectional size of the blocking block matches the cross-sectional contour of the blocking groove.

[0024] Furthermore, one end of the blocking block is connected to a reset block with an L-shaped structure, and one end of the reset block protrudes from the upper surface of the upper cover. A reset spring is connected between the reset block and the blocking groove.

[0025] The advantage of this utility model is that, through the coordinated design of the protective component and the locking component, the top cover can be quickly locked and fixed, preventing the top cover from becoming loose and causing contamination of the internal environment, while also providing a buffer protection effect for the culture dish.

[0026] Secondly, the addition of nutrient solution allows for quick addition of nutrient solution to sealed culture dishes, avoiding the risks associated with directly opening the culture dish to add nutrient solution. Attached Figure Description

Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0037] This application provides a culture dish for biological experiments, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0038] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0039] Please see Figure 1-7 In this embodiment, a biological experimental petri dish is provided, comprising: a box body 1, a petri dish 2 inside the box body 1, and a top cover 4 on the top of the petri dish 2; a locking component between the top cover 4 and the box body 1 for fixing the top cover 4; a protective component between the box body 1 and the petri dish 2 for reducing damage to the petri dish caused by external forces; and a filling component on the top cover 4 for adding nutrient solution to the petri dish 2.

[0040] The combination of the protective and locking components allows for quick locking and securing of the top cover 4, preventing it from becoming loose and contaminating the internal environment of the culture dish 2, while also providing a buffer protection for the culture dish 2. Secondly, the addition component allows for the rapid addition of nutrient solution to the sealed culture dish 2, avoiding the risks associated with directly opening the culture dish 2 to add nutrient solution. Example 2

[0041] Based on Embodiment 1, the protective component includes: a buffer plate 205 connected to the bottom of the petri dish 2, with multiple buffer springs 201 connected to the bottom of the buffer plate 205 and the inner wall of the bottom of the box 1; an annular block 101 connected to the inner wall of the box 1, with multiple connecting springs 202 connected between the upper surface of the buffer plate and the lower surface of the annular block 101, and a rubber ring 102 provided on the top of the annular block 101; a first rubber block 203 with an annular structure located on the outside of the petri dish 2; and multiple second rubber blocks 204 connected to the outside of the buffer plate 205, with the multiple connecting springs 202 evenly distributed in an annular array and the multiple second rubber blocks 204 evenly distributed in an annular array, one side of the first rubber block 203 connected to the inner wall of the annular block 101, and one side of the second rubber blocks connected to the inner wall of the box 1.

[0042] In biological experiments, petri dishes 2 are needed to carry microorganisms, bacteria, or fungi. During this process, the petri dishes are prone to collisions with external objects, which can damage them and contaminate the stored microorganisms, bacteria, or fungi. The box 1 protects the petri dishes 2, preventing direct contact between them and external objects. Furthermore, after a collision, the buffer springs 201 and 202 absorb vertical forces, reducing the force transmitted to the petri dishes 2. When subjected to vertical forces, the petri dishes 2 tend to move up and down, pulling on the first rubber block 203 and the second rubber block. When the petri dish 204 moves to one side, the first rubber block 203 and the second rubber block 204 undergo elastic deformation, generating elastic force to resist the tendency of the petri dish 2 to move. This allows the first rubber block 203 and the second rubber block 204 to act as dampers for the buffer spring 201 and the connecting spring 202, thereby achieving a buffering effect in the vertical direction. When subjected to external force in the horizontal direction, the first rubber block 203 and the second rubber block 204 will absorb the external force in the horizontal direction. At the same time, when the petri dish 2 has a tendency to move in the horizontal direction, the first rubber block 203 and the second rubber block 204 are squeezed and undergo elastic deformation to generate elastic force, thereby further buffering and protecting the petri dish 2 against external force in the horizontal direction. Example 3

[0043] Based on Embodiment 1, the locking assembly includes: two locking slots 401 formed on the outer surface of the upper cover 4, and the two locking slots 401 are symmetrically arranged; two symmetrically arranged moving slots 3 formed on the outer surface of the box body 1, a moving rod 301 passing through the moving slot 3, one end of the moving rod 301 extending into the locking slot 401 and having an inclined surface, a plurality of limiting slots 302 communicating with the moving slots 3 are formed inside the box body 1, a limiting plate 303 connected to the moving rod 301 is provided inside the limiting slot 302, and a limiting spring 304 is connected between the limiting plate 303 and the limiting slot 302.

[0044] When carrying, the top cover 4 is placed above the petri dish 2, and the bottom of the top cover 4 is inserted into the box body 1. During this process, the bottom of the top cover 4 contacts the inclined surface of the moving rod 301, and the moving rod 301 is squeezed into the moving groove 3. When the bottom of the top cover 4 contacts the upper surface of the annular block 101, the upper surface of the petri dish 2 contacts the inside of the top cover 4, and the slot 401 and the moving groove 3 are on the same plane. Then, the top cover 4 is rotated so that the slot 401 and the moving groove 3 are aligned. The moving rod 301 is then pushed into the slot 401 by the elastic force of the limiting spring 304, thus completing the locking and fixing of the top cover 4. At the same time, the top cover 4 will squeeze the rubber ring 102, causing the rubber ring 102 to deform and seal the gap between the top cover 4 and the annular block 101, thus sealing the space inside the box body 1 and protecting the storage environment inside the petri dish 2.

[0045] By setting the limiting plate 303 and the limiting groove 302, the moving direction and distance of the moving rod 301 can be limited. When it is necessary to remove the upper cover 4, the moving rod 301 is pulled to separate from the slot 401, the limitation on the upper cover 4 is released, and the upper cover 4 can be removed. Example 4

[0046] Based on Embodiment 1, the filling component includes: an injection tube 5 connected to the upper cover 4; a blocking groove 501 opened inside the upper cover 4, and the blocking groove 501 communicates with the injection tube 5; a blocking block 504 disposed inside the blocking groove 501, and the cross-sectional size of the blocking block 504 matches the cross-sectional contour of the blocking groove 501, one end of the blocking block 504 is connected to a reset block 503 with an L-shaped structure, and one end of the reset block 503 protrudes from the upper surface of the upper cover 4, and a reset spring 502 is connected between the reset block 503 and the blocking groove 501.

[0047] During the long-term culture of microorganisms, the nutrient solution inside the culture dish 2 is exhausted. At this time, it is necessary to open the sealed culture dish 2 and add nutrient solution to ensure the long-term culture and growth of the microorganisms inside. However, opening the sealed culture dish 2 has certain risks, such as increased risk of contamination, changes in the internal environment of the culture dish 2, physical disturbance, and temperature fluctuations. At this time, the nutrient solution can be directly added to the culture dish 2 through the setting of the injection tube 5, without opening the culture dish 2, thus reducing the impact of external environmental changes on the internal environment of the culture dish 2 and reducing the risk of microbial culture.

[0048] When injecting nutrient solution, the movable reset block 503 can be moved so that the reset block 503 can drive the blocking block 504 into the blocking groove 501, opening the injection tube 5. After the nutrient solution is injected, the reset block 503 is released. At this time, the reset block 503 rebounds under the action of the reset spring 502, thereby driving the blocking block 504 to be reinserted into the injection tube 5, re-sealing the injection tube 5.
