Description

Technical Field

[0001] This utility model relates to the field of microbial culture technology, specifically to a petri dish tray. Background Technology

[0002] A petri dish tray is a specialized tool used in laboratories for the safe and efficient carrying and transport of multiple petri dishes. It is made of materials such as stainless steel or high-temperature resistant plastic and has precise internal partitions to prevent the petri dishes from sliding and colliding, thus avoiding sample contamination and damage.

[0003] For example, the patent with authorization announcement number CN219689671U discloses a tray that facilitates the separate placement of microbial culture dishes. The position of the separator plate and separator rod can be adjusted according to the different sizes of culture dishes to form a grid. A batch of culture dishes can be placed in the grids in the tray. By moving the tray, a batch of culture dishes can be picked up and put in at the same time, and the culture dishes can be prevented from tipping over. It is time-saving and safe, but there are still the following improvements.

[0004] The common shortcomings of the aforementioned patent and some existing trays are that the tray is set horizontally, and the petri dishes are placed at the same horizontal height, making it difficult for staff to observe the side of the petri dishes from the side. In addition, the anti-tipping mechanism of the petri dishes is set on the outside of the petri dishes, which blocks the middle and lower part of the petri dishes, which is also not conducive to staff observing the side of the petri dishes. Utility Model Content

[0005] This invention provides a culture dish tray to address the problem that placing culture dishes at the same height and having the anti-tipping mechanism located on the outside of the culture dish makes it inconvenient for staff to check the side of the culture dish.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a petri dish tray, including a stepped tray for placing petri dishes. The stepped tray is stepped, which allows the petri dishes to be placed in a stepped manner without obstruction on the sides.

[0008] The stepped tray has a retaining ring that is movably installed on the outside to fix the position of the petri dish. The retaining ring is located on the upper part of the petri dish, making it easy for staff to check the side of the petri dish.

[0009] Preferably, the stepped tray has multiple cleaning through holes extending through its center.

[0010] Preferably, a tray base is fixedly installed at the bottom of the stepped tray, and multiple anti-slip pads are fixedly installed at the bottom of the tray base.

[0011] Preferably, a protective cover is movably mounted on the top of the stepped tray.

[0012] Preferably, multiple I-beams are fixedly installed on the outer side of the stepped tray, a movable plate is slidably installed through the inner side of the I-beams, a spring is fixedly installed between the movable plate and the I-beams, and a fixing ring is inserted into the inside of the movable plate.

[0013] Preferably, the movable plate has multiple insertion slots on its outer side, a fixing ring is inserted into the insertion slot, and a fixing magnet is fixedly installed on the inner side of the insertion slot.

[0014] Preferably, multiple label blocks are fixedly installed on the outside of the stepped tray, and each label block corresponds to an I-shaped block.

[0015] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0016] The positive and progressive effects of this utility model are as follows:

[0017] The fixing ring is attached to the outer top of the petri dish, without obstructing the middle and lower part of the petri dish. The stepped design of the stepped tray ensures that adjacent rows of petri dishes do not obstruct each other. The combination of the two makes it easy for staff to see the side of the petri dishes.

[0018] Staff can replace the corresponding fixing ring according to the size of the petri dish. The fixing ring is connected to the movable plate by the limiting of the insertion slot and the attraction of the fixing magnet. It is easy to insert and remove and easy to replace. The fixing ring can also be inserted into the corresponding insertion slot according to the height of the petri dish, which can meet the fixing of more types of petri dishes and has a wider range of applications.

[0025] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0026] like Figure 2 , Figure 4 As shown, the petri dish tray includes a stepped tray 4 for placing petri dishes. The stepped tray 4 is stepped, so that the petri dishes can be placed in steps without obstruction on the sides.

[0027] A fixing ring 6 is movably installed on the outer side of the stepped tray 4 to fix the position of the petri dish. The fixing ring 6 is located on the upper part of the petri dish, making it easy for staff to check the side of the petri dish.

[0028] Furthermore, such as Figure 2 , Figure 4 As shown, multiple I-beams 10 are fixedly installed on the outer side of the stepped tray 4, and a movable plate 7 is slidably installed through the inner side of the I-beams 10. A spring 11 is fixedly installed between the movable plate 7 and the I-beams 10, and is always in a compressed state. A fixing ring 6 is inserted into the inside of the movable plate 7.

[0029] In this embodiment, the operator lifts the fixing ring 6 and the movable plate 7 upwards, and places the culture dish directly below the fixing ring 6. The fixing ring 6 moves down and fits onto the outer top of the culture dish. The elastic force of the spring 11 keeps the movable plate 7 and the fixing ring 6 basically stationary, making the culture dish less prone to shaking and preventing obstruction of the middle and lower part of the culture dish. The stepped design of the stepped tray 4 ensures that adjacent rows of culture dishes do not obstruct each other. The combination of the two makes it easy for the operator to view the side of the culture dish.

[0030] Furthermore, such as Figure 2 As shown, the stepped tray 4 has multiple cleaning holes 5 through the middle. When the staff cleans the stepped tray 4, the cleaning water flows down through the cleaning holes 5, which is convenient for cleaning. Moreover, the cleaning holes 5 facilitate air flow, and the cleaned stepped tray 4 is easier to dry.

[0031] Furthermore, such as Figure 1 As shown, a tray base 1 is fixedly installed at the bottom of the stepped tray 4, and multiple anti-slip pads 2 are fixedly installed at the bottom of the tray base 1 to increase the friction between the device and the desktop or other placement platform, so that the device is placed stably and is not easy to slide.

[0032] Furthermore, such as Figure 1 As shown, a protective cover 3 is movably installed on the top of the stepped tray 4.

[0033] In this embodiment, after the petri dishes are placed, the staff can place the protective cover 3 on top of the stepped tray 4 to protect the petri dishes, effectively preventing damage from external forces and dust from falling, and reducing the possibility of the external environment affecting the experimental results of the petri dishes.

[0034] Furthermore, such as Figure 4 As shown, the movable plate 7 has multiple insertion slots 8 on its outer side. The fixing ring 6 is inserted into the insertion slot 8. A fixing magnet 9 is fixedly installed on the inner side of the insertion slot 8 to attract the fixing ring 6 and make it stable.

[0035] In this embodiment, the staff can replace the corresponding fixing ring 6 according to the size of the petri dish. The fixing ring 6 is connected to the movable plate 7 by the limiting of the insertion groove 8 and the attraction of the fixing magnet 9. It is easy to insert and remove and easy to replace. The fixing ring 6 can also be inserted into the corresponding insertion groove 8 according to the height of the petri dish, so as to meet the fixing of more types of petri dishes and the application range is wider.

[0036] Furthermore, such as Figure 2 , Figure 3 As shown, multiple label blocks 12 are fixedly installed on the outside of the stepped tray 4, and each label block 12 corresponds to an I-shaped block 10.

[0037] In this embodiment, staff can write relevant information about the petri dish on a card and then attach the card to the label block 12 for easy access to information about the experiments inside the petri dish.

[0038] Specific work steps

[0039] The staff lifts the fixing ring 6 and the movable plate 7 upwards, and places the petri dish directly below the fixing ring 6. The fixing ring 6 moves down and fits onto the outer top of the petri dish. The elastic force of the spring 11 keeps the movable plate 7 and the fixing ring 6 basically stationary, making the petri dish less prone to shaking and preventing obstruction of the middle and lower part of the petri dish. The stepped design of the stepped tray 4 ensures that adjacent rows of petri dishes do not obstruct each other. The combination of the two makes it easy for the staff to check the side of the petri dish.

[0040] Staff can replace the corresponding fixing ring 6 according to the size of the petri dish. The fixing ring 6 is connected to the movable plate 7 by the limiting of the insertion groove 8 and the attraction of the fixing magnet 9. It is easy to insert and remove and easy to replace.

[0041] The fixing ring 6 can also be inserted into the corresponding insertion slot 8 according to the height of the petri dish, so as to meet the fixing of more types of petri dishes and have a wider range of applications.

[0042] Staff can write relevant information about the petri dish on a card, and then attach the card to the label block 12 for easy access to information about the experiments inside the petri dish later.

[0043] After the petri dishes are placed, the staff can place the protective cover 3 on top of the stepped tray 4 to protect the petri dishes, effectively preventing damage from external forces and dust from falling, and reducing the possibility of the external environment affecting the experimental results of the petri dishes.

[0044] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
