AI Technical Summary
In microbial experiments, the flow of the culture medium is inconvenient, which makes it difficult to evenly spread the culture medium, affecting the uniform growth of bacterial fluid and bacterial species, and thus making it inconvenient to observe and count.
An antibacterial culture dish with a coating mechanism is designed, including a bottom cylinder and a cover plate. A connecting shaft is inserted into the socket at the center of the bottom of the cover plate. Four sets of scraping rods are welded horizontally below the connecting shaft. The scraping rod is rotated by the rotation of the cover plate to evenly scrape the unsolidified culture medium liquid.
The culture medium is evenly spread out, preventing the internal environment of the culture dish from contacting with the outside air, ensuring the uniform growth of bacterial fluid and bacterial species, and achieving single inoculation and fragmentation through the separation chamber to avoid contamination of bacterial groups, and facilitate later bacterial point counting.

Description
Technical Field
[0001] The utility model relates to the technical field of culture dishes, in particular to a bacteria-proof culture dish with a coating mechanism. Background Art
[0002] In microbial experiments, in order to cultivate bacterial colonies in specific areas, a tool called culture dishes is often used. This tool can be divided into disposable culture dishes made of plastic and reusable culture dishes made of glass. After the hot melt of the culture medium is introduced into the bottom plate, it is allowed to solidify after being left to stand for a period of time, and then the bacterial colony is inoculated.
[0003] If the melting temperature of the culture medium is not high enough or the external environment is too cold, the culture medium will often solidify into a jelly-like state in a short period of time. If there is a lack of spreading tools and the culture medium cannot be assisted to flow, the subsequent bacterial liquid and strains will be difficult to show a uniform growth trend, and observation and counting will be inconvenient.
[0004] Now, a novel antibacterial culture dish with a coating mechanism is proposed to solve the above problems. Utility Model Content

[0007] Preferably, a plug hole is drilled at the center of the bottom end of the cover plate, and a connecting shaft is longitudinally inserted into the plug hole.
[0008] Preferably, the scraper rod is in contact with the inner wall of the bottom cylinder at the bottom, and the side surface of the scraper rod can rotate in contact with the side wall of the bottom cylinder.
[0009] Preferably, four sets of sleeves are welded longitudinally on the outer surface of the connecting shaft, and snap-fit grooves are transversely arranged below the sleeves, and the sleeves are sleeved on the scraper rod by means of the snap-fit grooves.
[0010] Preferably, the thickness of the scraper rod matches the inner width of the clamping groove, and the scraper rod and the clamping groove are in the same vertical plane.
[0011] Preferably, the number of the scraper rods is the same as the clamping grooves, and the sleeve plate can guide the scraper rods to rotate horizontally.
[0012] Preferably, a first fan-shaped chamber is provided at each of the four corners of the bottom of the cover plate, a second fan-shaped chamber is provided at each of the four corners of the inner side of the cover plate, and a right-angle frame is fixed on the inner wall of the second fan-shaped chamber, a counting board is horizontally inserted in the second fan-shaped chamber, and grid lines are attached to the surface of the counting board, a card block is fixed on the outer edge of the counting board, an arc-shaped through groove is provided at the edge of the second fan-shaped chamber and the cover plate, and an engaging groove is provided on the counting board and the card block.
[0013] Preferably, the counting board is embedded in the arc-shaped through groove by means of the engaging groove, and the edge of the counting board can be attached to the right-angle frame in the second fan-shaped chamber.
[0014] Compared with the prior art, the utility model has the following beneficial effects: the antibacterial culture dish with the spreading mechanism not only realizes the auxiliary flattening of the culture medium and the separation of the growth space, but also realizes the auxiliary bacterial cell counting;
[0015] Four groups of scraping rods are welded horizontally below the surface of the connecting shaft. After pouring hot melt culture medium into the bottom cylinder, the cover plate is covered. At this time, the vertical connecting shaft has been inserted into the plug hole at the center of the bottom of the cover plate. When the cover plate rotates, it can drive the connecting shaft and the four scraping rods at the bottom to rotate together, so that the unsolidified culture medium liquid in the bottom cylinder can be evenly scraped. This movement is carried out between the closed bottom cylinder and the cover plate, which can prevent the internal environment of the culture dish from contacting with the outside air and can also flatten the condensed culture medium inside.
[0016] Four sets of sleeves are welded longitudinally on the outer surface of the connecting shaft, and sleeves are vertically welded on the four sides of the bottom of the cover plate. After the connecting shaft is longitudinally inserted into the insertion hole, the transverse clamping groove at the bottom of the sleeve is immediately sleeved on the scraper rod, and then four isolated chambers are formed in the bottom tank. Bacteria can be inoculated on the surface of these spaces respectively, and single inoculation is implemented for piecewise growth, which can also prevent adjacent bacteria from contaminating each other and affecting the later counting;
