Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a culture dish placement device which is convenient for observation. Background Art

[0002] In the scientific fields of agriculture, forestry, and medical treatment, microbial or cell culture experiments are often carried out in culture dishes. The culture dishes used above are usually discs with a diameter of 9 cm, made of glass or plastic. After inoculating microorganisms or cells, the culture dishes need to be placed in an incubator for constant temperature culture for a certain period of time, and then the growth of microorganisms or cells is observed. At present, generally multiple culture dishes are directly stacked in an incubator at one time, and there are multiple culture dishes that are unstable to stack, and the operations such as taking and placing and transferring of the culture dishes are inconvenient, and it is easy to cause many problems such as falling and damage during the process of taking and placing, and the operation efficiency is low. In addition, during the test, it is often necessary to accurately measure the mycelial growth of the colony, and take pictures and record the colony morphology inside the culture dish, so as to facilitate the collation of information such as later test data. Mycelium usually grows radiantly around the inoculation point in the plate culture medium. Researchers currently use the cross method to measure the mycelial growth, but errors are prone to occur in the process of measuring the diameter of the colony using a ruler, and the operation is relatively cumbersome. Therefore, a multifunctional culture dish placement device is needed that is convenient for observation, has the function of measuring colony diameter, and has a built-in auxiliary background plate for taking photos.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model discloses a culture dish placement device for convenient observation. The coordinated use of the arc-shaped positioning plate and the elastic clip can realize the rapid installation and removal of the background plate. The background plate can be located directly below the transparent bottom plate by making the outer edge of the background plate contact with the inner wall of the arc-shaped positioning plate. The background plate is firmly attached to the bottom surface of the transparent bottom plate through the elastic squeezing of the elastic clip. The growth amount of mycelium can be measured through the scale lines on the background plate and the transparent bottom plate. The circular plate structure of the background plate only requires rotating the background plate to make the scale lines on the background plate close to the mycelium. Without moving the culture dish, the experimental steps are reduced, and the multi-directional, rapid and accurate measurement of the mycelium growth diameter is realized. The device has a simple structure, is easy to operate, and shortens the experimental time.

[0015] 2. The utility model exemplifies a culture dish placement device that is convenient for observation. When it is necessary to take photos of the mycelium growth, the background plate can be replaced with a black non-reflective plate according to actual needs, so that the scale line is white. Due to the transparent nature of the transparent bottom plate, researchers can directly take photos and keep them on file without taking out the culture dish, which facilitates the researchers' photographic records.

[0016] 3. The culture dish placement device for convenient observation in the example of the utility model is convenient for taking and storing culture dishes through the rotation connection between the support column and the placement plate. The setting of the damping component can enable the placement plate to hover at any position. The bottom surface of the lower pressure plate presses the surface of the end plate downward, and the extrusion friction generated by the two hinders the rotation of the end plate, so that after a single culture dish is rotated out by the placement plate, it can stay stably in the ideal observation position. The structure is simple and easy to operate. At the same time, it can also avoid rotation and movement due to external environmental factors when observing the growth of mycelium in the culture dish, which affects the observation of the mycelium in the culture dish.

[0017] 4. The culture dish placement device for convenient observation in the utility model, through the sliding cooperation between the stopper and the groove, can quickly move to the storage position when the placement plate is rotated into between the top plate and the base, thereby playing a role in rapid positioning.

[0033] Embodiment 1:

[0034] refer to Figure 1-6 A culture dish placement device for convenient observation is shown, comprising a top plate 1, a base 2, a culture dish 6 and a plurality of placement trays 5, a support plate 3 and a support column 4 are detachably fixed between the top plate 1 and the base 2, one side of the placement tray 5 is rotatably connected to the support column 4, the culture dish 6 is located in the placement tray 5, a transparent bottom plate 9 is provided at the inner bottom of the placement tray 5, and an arc-shaped positioning plate 13 is fixed to the bottom surface of the placement tray 5, an elastic clip 14 is embedded and fixed at the bottom of the arc-shaped positioning plate 13, a background plate 15 is clamped and fixed between the elastic clip 14 and the transparent bottom plate 9, a mushroom cake positioning circle 16 is provided at the center point of the background plate 15, and a plurality of scale lines 17 radially distributed along the center point of the background plate 15 are provided on the upper surface of the background plate 15;

[0035] A plurality of cylinders 7 are arranged on the support column 4, and end plates 10 and stoppers 11 are fixed to the circumferential sides of the plurality of placement plates 5. The end plates 10 are rotatably connected to the cylinders 7, and grooves 20 are provided at positions corresponding to the stoppers 11 on one side of the support plate 3, and the stoppers 11 are slidably fitted in the grooves 20.

[0036] When using the device, the placement tray 5 is used to place the culture dishes 6. The multiple placement trays 5 between the top plate 1 and the base 2 can accommodate and store multiple culture dishes 6. Through the rotational connection between the end plate 10 and the cylinder 7, the individual culture dishes 6 can be pulled out one by one from between the top plate 1 and the base 2 by pulling out the placement tray 5. Since the transparent bottom plate 9 has a transparent property, the background plate 15 can be placed between the elastic clip 14 and the transparent bottom plate 9, so that the edge of the background plate 15 contacts the inner wall of the arc-shaped positioning plate 13. At this time, the background plate 15 is just located directly below the transparent bottom plate 9, and the elastic clip 14 clamps the background plate 15 to fix it. The background plate 15 is rotated as needed to adjust the measurement orientation of the background plate 15 for the mycelium growth amount, so that the scale line 17 above the background plate 15 is close to the mycelium growth direction, and the mycelium growth diameter can be measured by observing the scale line 17. According to the different light requirements of different bacterial species, researchers can remove the background plate 15 or replace it with a background plate 15 with different light transmittance according to actual conditions. When the background plate 15 is not removed, the operator can refer to the bacterial cake positioning circle 16 on the background plate 15 to quickly lock the center position of the culture dish 6 and pour the bacterial solution, saving operation time.

[0037] In order to facilitate the pulling and storage of the placement tray 5, in this embodiment, a pull plate 12 is provided on the outside of the placement tray 5. The placement tray 5 is a disc structure, and the end plate 10 and the stopper 11 are located on a diameter of the placement tray 5. The placement tray 5 can be driven to rotate by pulling the pull plate 12, and the placement tray 5 with a disc structure is convenient for placing the culture dish 6.

[0038] In this embodiment, Figure 4 , 5 As shown, the background plate 15 is a circular plate structure, the diameter of the background plate 15 is the same as the diameter of the transparent bottom plate 9, the outer edge of the background plate 15 contacts the inner side of the arc-shaped positioning plate 13, and a plurality of scale lines 17 are arranged in a circular array on the eight radii of the background plate 15.

[0039] In this embodiment, two mounting plates 19 are fixed to the sides of the top plate 1 and the base 2, and bolt columns 18 are provided at both ends of the support plate 3 and the support column 4 for being fixedly connected to the mounting plates 19. The top end of the bolt column 18 penetrates the mounting plate 19 and the two are stably fixed together by nuts, and the support plate 3, the support column 4, the top plate 1 and the base 2 are fixedly connected to form an outer frame.

[0040] Embodiment 2:

[0041] The features that are the same as those of the first embodiment are not repeated here. The features that are different from the first embodiment are that a damping component 8 is slidably fitted on the cylinder 7, and the damping component 8 includes a lower pressure plate 81 slidably sleeved on the outer side of the cylinder 7. The lower pressure plate 81 controls the stopping of the end plate 10 by frictional contact with the end plate 10. A plurality of guide rods 83 are fixed to the upper surface of the lower pressure plate 81. The top ends of the guide rods 83 slide through the support column 4, and a spring 82 is fixed between the lower pressure plate 81 and the support column 4. The spring 82 surrounds the outer side of the cylinder 7, and the bottom surface of the lower pressure plate 81 is in compression contact with the upper surface of the end plate 10, and the bottom surface of the lower pressure plate 81 is provided with anti-slip grooves 84.

[0042] The damping member 8 is provided so that the placement plate 5 can be suspended at any position. Under the action of the spring 82, the bottom surface of the lower pressing plate 81 presses the surface of the end plate 10 downward, and the extrusion friction force generated by the two hinders the rotation of the end plate 10, so that after the single culture dish 6 is rotated out by the placement plate 5, it can be stably kept at the ideal observation position. The structure is simple and easy to operate. It can avoid the rotation and movement caused by the influence of external weak force when observing the growth of mycelium in the culture dish 6, which affects the observation of mycelium in the culture dish 6, and facilitates the researchers to observe the mycelium. The setting of the guide rod 83 can effectively prevent the rotation of the lower pressing plate 81, and the setting of the anti-slip pattern 84 increases the extrusion friction force of the lower pressing plate 81 on the end plate 10. The operator needs to manually apply a certain external force on the placement plate 5 to resist the friction resistance between the lower pressing plate 81 and the end plate 10, so that the placement plate 5 can rotate normally.

[0043] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.

[0044] Except for the technical features described in the specification, the remaining technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present utility model, the remaining technical features will not be described here in detail.
