As a preferred solution of the present invention, the second structural ring and the vertical bridging pieces and circular connecting pieces placed inside the tray;

As a preferred solution of the present invention, the first structural ring is also provided with a lifting part, including a helical structure and a hanging groove structure;

As a preferred solution of the present invention, the main body of the device is a stainless steel sleeve structure;

When the above-mentioned device is in use, the whole device is placed on a horizontal plane, and then the placement plate is moved to the top of the sleeve, and a plurality of petri dishes are stacked vertically on the corresponding petri dish placement tray, and then the plurality of petri dishes are placed Slowly transfer batches of the placed dish to the bottom of the designated sleeve until the last Petri dish is no higher than the first construction ring. When the culture dish is taken off from the device, the placing plate is gradually moved up, and when the culture surface is higher than the second structural ring, the culture dish is removed one by one. The above-mentioned device can transfer the petri dishes in batches, and arrange the petri dishes in layers without interfering with each other, and each petri dish can be restrained, not easy to drop, and will not cause pollution due to dumping. Moreover, the above-mentioned device also has the advantages of simple structure, better centralized transfer of culture dishes in batches, and more convenient operation and use.

The petri dish transfer device increases the number of transferred petri dishes by setting a movable door and a hanging slot structure, which solves the problem of limited number of petri dishes transferred by hand, and can transfer more petri dishes at one time, with high safety, and avoids the need to transfer petri dishes by hand. Easy to scatter and not stable enough to ensure a high degree of safety, and there is no need to worry about the petri dish being scattered during the transfer process. The stability is good, avoiding the uneven distribution of materials in the dish caused by the easy shaking of the hand-transferred petri dish, and it can maintain the level during the transfer process. The distribution of medium and culture materials is not affected;

Compared with the prior art, the present invention has the following advantages and beneficial effects:

The size of the structural ring can be adjusted according to one's own needs to adapt to culture dishes of different sizes, which improves the versatility of placing the plate and the sleeve, and makes the operation more flexible, which has universal promotional significance. Not only the utilization rate of the placing tray is improved, but also the amount of placement and transfer of the petri dishes on the placing tray is greatly increased. The dodge door that offers on the first structure ring is to solve the situation that the placement tray is stuck when the bracket or the placement tray is partially rusted, and if it is pulled out forcefully, it may cause the culture medium in the culture dish to splash. The helical structure of the lifting part increases the friction and stability of the hand-held part. The design of the hanging groove structure can ensure high safety, ensure the stability of the sleeve structure during the transfer process, and avoid shaking during the transfer of the petri dish. , keep it level throughout the transfer process.
