Description

Technical Field

[0001] This utility model relates to the field of petri dishes, specifically a petri dish used for food testing. Background Technology

[0002] Petri dishes are one of the most basic and important tools in microbiology and food testing, mainly used for the isolation, culture, counting and identification of microorganisms. Although technological advancements have promoted the popularization of rapid testing methods, the advantages of petri dishes in terms of viable cell confirmation, regulatory compliance and cost-effectiveness remain irreplaceable. In the future, optimizing the composition of culture media (such as rapid testing media) or combining them with automated equipment (such as fully automated colony counters) will be the key to improving their efficiency.

[0003] Petri dishes play the role of microbial "amplifiers" and "observation windows" in food testing. It is often necessary to set up petri dishes with the required testing conditions and set up multiple control groups in the same testing environment. In traditional food testing, petri dishes are often arranged haphazardly when set up, and the placement of testing petri dishes and control groups in the testing environment is relatively chaotic. This can easily lead to the inability to clearly and effectively identify the differences between the petri dishes, and individual petri dishes may be accidentally dropped when collecting samples. Utility Model Content

[0004] To address the shortcomings of existing technologies, the placement of test and control petri dishes in the testing environment is often chaotic, making it difficult to clearly and effectively distinguish between the different petri dishes, and there are also problems such as individual petri dishes being accidentally dropped during sample recovery. This invention proposes a petri dish for food testing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a petri dish for food testing, including an outer shell, a base fixedly connected to one side of the outer shell, and an arrangement mechanism provided in the inner cavity of the outer shell;

[0006] The arrangement mechanism includes a central column, one end of which is fixedly connected to one side of the base. A spiral groove is formed on the surface of the central column, and a movable rod is slidably connected to the inner wall of the spiral groove. A through groove is formed on the surface of the outer shell, and the surface of the movable rod is slidably connected to the inner wall of the through groove. One end of the movable rod is fixedly connected to a platform.

[0007] Preferably, the surface of the central column is provided with a filling groove, and one end of the central column is provided with a top cover.

[0008] Preferably, a limiting cylinder is slidably connected to the surface of the movable rod, one side of the limiting cylinder is slidably connected to the inner wall of the outer shell, and a connecting plate is fixedly connected to the surface of the central column, the surface of the connecting plate being fixedly connected to the inner wall of the outer shell.

[0009] Preferably, the inner wall of the limiting cylinder is provided with a sliding groove, and a slider is slidably connected to the inner wall of the sliding groove. The surface of the slider is slidably connected to the inner cavity of the movable rod.

[0010] Preferably, the inner wall of the stage is fitted with the petri dish body, and a through hole is provided on one side of the stage.

[0011] Preferably, the inner cavity of the stage is slidably connected to a top plate, one side of which is attached to one side of the culture dish body, and a connecting rod is fixedly connected to one side of the top plate, the surface of which is slidably connected to the inner wall of the through hole.

[0012] Preferably, one end of the connecting rod is provided with an elastic sleeve, one side of the elastic sleeve is attached to one end of the connecting rod, and one side of the elastic sleeve is fixedly connected to the inner wall of the platform.

[0013] The advantages of this utility model are:

[0014] This invention, through the setting of an arrangement mechanism, allows for the setting of food testing petri dishes. By pulling a movable rod, one end of the rod abuts against the inner wall of a spiral groove, and the rod slides along the groove to position it appropriately for the operator. The petri dish body is then placed on the stage, and the food sample to be tested is filled into the petri dish body. After setting the petri dish body, the movable rod is slid and pushed, engaging with the bottom of the filling groove. This achieves a neat arrangement of the petri dishes, solving problems such as the chaotic placement of testing and control petri dishes in the testing environment, making it difficult to clearly distinguish between different petri dishes, and the accidental dropping of individual petri dishes during sample recovery.

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a petri dish for food testing. (Refer to...) Figures 1 to 3 A petri dish for food testing includes an outer shell 1, a base 2 fixedly connected to one side of the outer shell 1, and an arrangement mechanism 3 provided in the inner cavity of the outer shell 1.

[0025] The arrangement mechanism 3 includes a central column 301, one end of which is fixedly connected to one side of the base 2. A spiral groove 302 is formed on the surface of the central column 301, and a movable rod 303 is slidably connected to the inner wall of the spiral groove 302. A through groove 304 is formed on the surface of the outer shell 1, and the surface of the movable rod 303 is slidably connected to the inner wall of the through groove 304. One end of the movable rod 303 is fixedly connected to a stage 305. By setting up the arrangement mechanism 3, when setting up a petri dish for food testing, the food sample to be tested needs to be placed inside the petri dish body 10, and the movable rod 303 is pulled to move the rod 303. 3. Pull out the movable rod 303 from the depth of the filling groove 4 so that one end of the movable rod 303 abuts against the inner wall of the spiral groove 302. Then move the movable rod 303 in the spiral groove 302 to set the movable rod 303 in a position suitable for the staff to conduct the experiment. Then place the petri dish body 10 in the stage 305 and fill the petri dish body 10 with the food sample to be tested. After the food sample in the petri dish body 10 is set, slide and push the movable rod 303 so that the movable rod 303 is engaged with the bottom of the filling groove 4. Repeat this setting of the petri dish body 10 many times to achieve a neat arrangement of the petri dish body 10.

[0026] Reference Figure 3 The surface of the central column 301 is provided with a filling groove 4, and a top cover 5 is provided at one end of the central column 301. By providing the filling groove 4, the depth of the filling groove 4 is relatively deeper than that of the spiral groove 302. The movable rod 303 in the filling groove 4 can be pulled outward and engaged with the spiral groove 302. One end of the filling groove 4 is open, and one end of the movable rod 303 can be directly placed in the filling groove 4. The completed culture dish bodies 10 are arranged in the filling groove 4 in sequence. By providing the top cover 5, it can be engaged with one end of the outer shell 1 after all the culture dish bodies 10 have been placed, thus blocking the filling groove 4 and preventing the device from continuing to fill the culture dish bodies 10, as well as preventing the already filled culture dish bodies 10 from detaching from the device.

[0027] Reference Figure 3 A limiting cylinder 6 is slidably connected to the surface of the movable rod 303. One side of the limiting cylinder 6 is slidably connected to the inner wall of the outer shell 1. A connecting plate 7 is fixedly connected to the surface of the central column 301. The surface of the connecting plate 7 is fixedly connected to the inner wall of the outer shell 1. By setting the limiting cylinder 6, the limiting cylinder 6, due to its arc shape, can slide against the central column 301 and the outer shell 1 in the space between the central column 301 and the outer shell 1 without rotating. Thus, the limiting cylinder 6 can limit the movable rod 303 and prevent the movable rod 303 from sliding and deviating due to gravity in the spiral groove 302. By setting the connecting plate 7, the central column 301 can be connected to the outer shell 1 without affecting the movement of the movable rod 303, so as to support the outer shell 1.

[0028] Reference Figure 4 The inner wall of the limiting cylinder 6 is provided with a sliding groove 8, and a slider 9 is slidably connected to the inner wall of the sliding groove 8. The surface of the slider 9 is slidably connected to the inner cavity of the movable rod 303. By setting the sliding groove 8 and the slider 9, the two ends of the sliding groove 8 are closed, so that the slider 9 cannot be disengaged from the sliding groove 8. The slider 9 can be stuck between the surface of the movable rod 303 and the inner wall of the limiting cylinder 6, so as to prevent the movable rod 303 from rotating relative to the limiting cylinder 6 without affecting the axial movement of the movable rod 303, and ensure that the stage 305 at one end of the movable rod 303 does not tilt when the culture dish body 10 is set.

[0029] Reference Figure 5 The inner wall of the stage 305 is fitted with a petri dish body 10. A through hole 11 is provided on one side of the stage 305. By setting the petri dish body 10, the food sample to be tested in the petri dish body 10 can be tested and observed. By setting the through hole 11, the connecting rod 13 can be moved in the stage 305.

[0030] Reference Figure 5A top plate 12 is slidably connected to the inner cavity of the stage 305. One side of the top plate 12 is attached to one side of the petri dish body 10. A connecting rod 13 is fixedly connected to one side of the top plate 12. The surface of the connecting rod 13 is slidably connected to the inner wall of the through hole 11. By setting the top plate 12, which is located at the bottom of the petri dish body 10, the petri dish body 10 is supported. By setting the connecting rod 13, when it is necessary to remove the petri dish body 10 from the stage 305, the top plate 12 can be lifted by lifting the connecting rod 13 from below, thereby lifting the petri dish body 10 for easy removal.

[0031] Reference Figure 5 One end of the connecting rod 13 is provided with an elastic sleeve 14. One side of the elastic sleeve 14 is attached to one end of the connecting rod 13, and one side of the elastic sleeve 14 is fixedly connected to the inner wall of the stage 305. By providing the elastic sleeve 14, when the petri dishes 10 are arranged in sequence, one end of the connecting rod 13 may come into contact with the lid of the petri dish 10, causing mechanical damage. The elastic sleeve 14 can reduce friction and prevent damage.

[0032] Working principle: Open the top cover 5 to expose one end of the filling groove 4. One end of the movable rod 303 is directly positioned within the filling groove 4. Pull the movable rod 303 out from the depth of the filling groove 4 until one end of the movable rod 303 abuts against the inner wall of the spiral groove 302. Then, move the movable rod 303 within the spiral groove 302 to a suitable position for the operator's experiment. Afterward, place the petri dish body 10 into the stage 305 and fill the petri dish with the food sample to be tested. After setting the food sample inside the petri dish body 10, slide and push the movable rod 303 so that the movable rod 303 engages with the bottom of the filling groove 4. Repeat this operation multiple times to achieve a neat arrangement of the petri dish bodies 10. Cover the top cover 5 and place the device and sample in the experimental environment to stand. After a certain period of time, when it is necessary to remove the petri dish body 10 from the stage 305, the top plate 12 can be raised by lifting the connecting rod 13 from below, thereby lifting the petri dish body 10 for easy removal.
