Description

Technical Field

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

[0002] A petri dish is a laboratory vessel used for the culture of microorganisms or cells. It consists of a flat, disc-shaped base and a lid. Petri dishes are mainly made of plastic, glass, and stainless steel. Glass petri dishes can be used for the culture of plant materials, microorganisms, and adherent culture of animal cells. This type of vessel is designed to facilitate the culture, observation, and manipulation of cells in biological experiments. Stainless steel petri dishes are widely used in research such as tissue engineering, cell culture, and protein crystallization.

[0003] When conducting microbial cell culture experiments, the experimenter needs to open the culture dish with one hand, so that the dish body and the lid form a certain opening angle. Then, the inoculation loop is inserted into the opening between the dish body and the lid, and the bacteria on the inoculation loop are inoculated into the dish body using the streak method.

[0004] A search revealed that patent application number 202420298519.1 discloses a petri dish comprising: a base box having a bottom groove at its bottom end, a fixing ring on the outer wall of the base box, a first limiting ring connected to the outer wall of the base box, and a first locking tooth at the bottom end of the first limiting ring; and a lid having anti-slip texture on its outer wall, a second limiting ring on its inner wall, a second locking tooth on the outer wall of the second limiting ring, and a retaining ring at the top end of the lid.

[0005] Although the petri dish can prevent the lid from falling off and reduce contamination during the experiment by using the first limiting ring, the first locking tooth, the second limiting ring, and the second locking tooth, it is not convenient to use one hand to form a certain opening angle between the bottom box and the lid when inoculating the bacterial colony, which makes it inconvenient to streak the bacterial culture.

[0006] Therefore, we propose a culture dish for microbial cells. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a culture dish for microbial cells, which solves the problem that existing devices are inconvenient for using one hand to open and close the bottom box and lid at a certain angle when inoculating microorganisms, making it difficult to streak the microorganisms.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a culture dish for microbial cells, comprising a dish body and a dish lid, wherein the dish lid is snapped onto the top of the dish body;

[0009] A rotating assembly is provided on the outer side of the dish body and the dish lid;

[0010] The rotating assembly includes a rotating ring, ear plates, threaded rods, nuts, rotating rods, and connecting blocks. The rotating ring is rotatably mounted on the outside of the dish body. Ear plates are symmetrically distributed on the left and right sides of the rotating ring's arc surface. Threaded rods are fixedly installed on the top surface of the ear plates. Rotating rods corresponding to the positions of the ear plates are fixedly installed on the bottom of the left and right sides of the dish lid's arc surface. A connecting block corresponding to the position of the threaded rod is rotatably mounted on the end of the rotating rod away from the dish lid. The connecting block is movably fitted onto the outer surface of the threaded rod on the same side. A nut is threaded onto the top end of the threaded rod.

[0011] Preferably, an annular groove is formed on the arc surface of the dish body, and the inner ring of the rotating ring is rotatably fitted inside the annular groove. The rotating ring, ear plate, threaded rod, nut, rotating rod and connecting block are all made of stainless steel. The annular groove facilitates the restriction of the position of the rotating ring. Stainless steel has stability and smoothness, is easy to clean and disinfect, and can achieve the disinfection effect by soaking in a specific disinfectant solution.

[0012] Preferably, the swivel and the ear plate are integrally formed, and the threaded rod is welded to the top surface of the ear plate. The integrally formed structure is stable and has a long service life.

[0013] Preferably, the bottom surface of the plate lid is flush with the top surface of the ear plate, and the top surfaces of the threaded rod and nut are also flush with the top surface of the plate lid. After inoculation, the culture dish is inverted to facilitate inoculation. Inverting the culture medium is an important operation method in microbial culture. It can effectively avoid contamination, maintain a moist growth environment, facilitate operation and use, promote the growth of strains and the formation of single colonies, and enhance the stability and safety of the experiment.

[0014] Preferably, the dish body and lid are made of transparent glass to facilitate observation of the reproduction of microbial cells in the culture dish.

[0015] This invention provides a culture dish for microbial cells. It has the following beneficial effects:

[0016] This microbial cell culture dish, with its rotating ring, ear plate, threaded rod, nut, rotating rod, and connecting block, can limit the position of the dish body and lid, preventing the lid from falling off the dish body. The lid can also tilt around the rotating rod to facilitate inoculation of microbial cells inside the dish body. This design allows the dish body and lid to be moved at an opening angle for easy inoculation. It is simple and convenient to use, solving the problem of existing devices where it is inconvenient to use one hand to open the bottom box and lid at a certain angle during bacterial inoculation, making streaking of the bacterial culture difficult.

[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 protection scope of the present utility model.

[0023] Example 1:

[0024] like Figure 1-4 As shown: The device includes a dish body 1 and a lid 2. The lid 2 is snapped onto the top of the dish body 1. A rotating assembly 3 is provided on the outer side of the dish body 1 and the lid 2. The rotating assembly 3 includes a rotating ring 31, ear plates 32, threaded rods 33, a nut 34, a rotating rod 35, and a connecting block 36. The rotating ring 31 is rotatably positioned on the outer side of the dish body 1. Symmetrically distributed ear plates 32 are provided on the left and right sides of the arc surface of the rotating ring 31. Threaded rods 33 are fixedly installed on the top surface of the ear plates 32. Rotating rods 35, corresponding to the positions of the ear plates 32, are fixedly installed on the bottom of the left and right sides of the arc surface of the lid 2. The end of the rotating rod 35 furthest from the lid 2 is rotatably mounted to a position corresponding to the threaded rod 33. The corresponding connecting block 36 is movably fitted on the outer surface of the threaded rod 33 on the same side. The top of the threaded rod 33 is threaded with a nut 34. Through the arrangement of the rotating ring 31, ear plate 32, threaded rod 33, nut 34, rotating rod 35 and connecting block 36, the position of the dish body 1 and the dish cover 2 can be limited to prevent the dish cover 2 from falling off the dish body 1. The dish cover 2 can be tilted about the rotating rod 35 as the axis to facilitate the inoculation of microbial cells into the inside of the dish body 1. This achieves the purpose of making the dish body 1 and the dish cover 2 form a movable opening and closing angle for inoculation, which is simple and convenient to use.

[0025] Example 2:

[0026] like Figure 1-4 As shown: the swivel ring 31 and the ear plate 32 are integrally formed structures, and the threaded rod 33 is welded to the top surface of the ear plate 32. The integrally formed structure is stable and has a long service life.

[0027] The bottom surface of the lid 2 is flush with the top surface of the ear plate 32, and the top surfaces of the threaded rod 33 and the nut 34 are also flush with the top surface of the lid 2. This allows the culture dish to be inverted after inoculation. Inverting the culture medium is an important operation method in microbial culture. It can effectively avoid contamination, maintain a moist growth environment, facilitate operation and use, promote the growth of strains and the formation of single colonies, and enhance the stability and safety of the experiment.

[0028] The dish body 1 and the dish lid 2 are made of transparent glass, which facilitates the observation of the reproduction of microbial cells in the culture dish.

[0029] The working principle and usage process of this utility model: This culture dish for microbial cells is used by placing it on the lab bench and then moving the lid 2 upwards by hand. At this time, the rotating rod 35 and the connecting block 36 will move upwards together along the side wall of the threaded rod 33. Then, the lab technician tilts the lid 2 by hand, and the lid 2 will rotate around the rotating rod 35 as an axis, thus forming an opening between the dish body 1 and the lid 2. The lab technician inserts the inoculation loop into the opening and uses the streak method to inoculate the microbial cells on the inoculation loop into the dish body 1. The dish body 1 can be rotated on the rotating ring 31, and the angle of the dish body 1 can be adjusted to facilitate inoculation at different positions inside the dish body 1. After inoculation, the lab technician inverts the culture dish and places it in the incubator. When it is necessary to remove the microbial cells inside the dish body 1, the nut 34 can be unscrewed to separate the dish body 1 and the lid 2, and then the microbial cells in the dish body 1 can be removed.
