[0002] In the process of drug inspection and microorganism detection, culture dish is the commonly used experimental apparatus. Among them, the drug inspection needs to strictly monitor the microorgan organism pollution of drug, usually through the preparation of culture medium, inoculation sample, place into culture dish and then constant temperature culture to complete. However, in actual operation, it often needs to face the processing and preservation of a large number of culture dishes. Because the culture dish is small in size, the number is large, and it is easy to slide during stacking storage, the sliding and even the overturning of the culture dish may lead to pollution or experimental failure.

[0003] The patent with publication number CN222082789U discloses a stackable culture dish, which comprises a dish body, a fixing ring is arranged at the bottom of the dish body and fixedly connected with the dish body, a dish cover is arranged at the upper end of the dish body and connected with the dish body, a fixing rod is arranged at the upper end of the dish cover and fixedly connected with the dish cover, a supporting groove is arranged at the bottom of the dish body, a clamping block is arranged in the supporting groove, springs are arranged at the two sides of the clamping block, one end of each spring is fixedly connected with the clamping block, and the other end of each spring is fixed in the supporting groove, and a fixing hole is arranged between the clamping blocks, the diameter of the fixing hole is smaller than the outer diameter of the fixing rod. The purpose of the patent is to solve the problems of instability of the stacked culture dish and inconvenience of taking the placed culture dish, and to avoid contamination of the culture medium.

[0004] Although the above-mentioned prior art can stack and position two adjacent culture dishes, the design still has certain limitations: first, the positioning effect generated by the clamping of the fixing cap by the spring and the clamping block has the problem of insufficient stability, especially when multiple culture dishes are stacked and moved at the same time, since the spring has elastic deformation characteristics, the culture dish at the middle position may displace along the extension direction of the spring, resulting in misalignment or even sliding, which undoubtedly increases the risk of experimental contamination and failure; second, the stacking structure of the culture dish needs to additionally increase a plurality of fixing rods, clamping blocks, springs and other components on the culture dish, which not only increases the production cost and complexity of the culture dish, but also the additional components may be aged and failed under high temperature and high humidity culture conditions, further affecting the stability of the stacking and the durability of the repeated use, therefore, we propose a microorganism culture dish stacking auxiliary device.
