Description

Technical Field

[0001] This utility model relates to the field of petri dish technology, and in particular to a multi-layer three-dimensional petri dish that can rapidly prepare flat plates. Background Technology

[0002] In microbial (bacteria, fungi) culture experiments, preparing culture media is an essential step. This involves preparing a suitable culture medium for microbial growth, placing the medium in a petri dish, allowing it to cool and solidify, and then inoculating the dish with the bacterial strain. The procedure is as follows: Autoclave the culture medium; remove it and allow it to cool to 50°C in a sterile environment, then add antibiotics (not heat-resistant). Pour the culture medium liquid into each petri dish, allow it to cool to room temperature and solidify, and repeat the process.

[0003] Because some experiments require large quantities of the aforementioned solid culture medium, hundreds of preparations are needed during the preparation process, which is inconvenient to operate, easily leads to hand fatigue and accidents; the amount of liquid poured each time is uneven; liquid splashing can cause burns; and the slow speed causes the culture medium to solidify before it is poured out. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layered three-dimensional culture dish that can rapidly prepare flat plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-layer three-dimensional culture dish for rapid preparation of flat plates includes a base plate, a flow-dividing mechanism on the top of the base plate, a material tube fixedly connected to the top of the base plate, a funnel fixedly connected to the top of the material tube, multiple guide tubes fixedly connected to one side of the material tube, and multiple quick-release mechanisms on one side of the material tube.

[0007] The quick-release mechanism includes a second fixing block fixedly connected to one side of the material tube, a slot on the top of the second fixing block, a first fixing block slidably connected to one side of the material tube, a rod fixedly connected to the bottom of the first fixing block and inserted into the slot, and a petri dish body fixedly connected to one end of the first fixing block.

[0008] As a further embodiment of this utility model, the top of the funnel is provided with a groove, a dust cover is inserted into the groove, and an anti-slip ball is fixedly connected to the top of the dust cover.

[0009] As a further embodiment of this utility model, a connecting rod is fixedly connected inside the funnel, and a guide rod is integrally formed on one side of the connecting rod.

[0010] As a further improvement of this invention, the insertion rod is a magnetic rod.

[0011] As a further embodiment of this utility model, the components in the quick-release mechanism are replaced with a fixed frame that is fixedly connected to one side of the material tube. One end of the fixed frame is detachably connected to a placement plate by bolts. The placement plate has a slot, and the culture dish body can be inserted into the slot.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem of repetitive liquid pouring by using a feed pipe and multiple guide pipes, enabling accurate liquid addition without repeated operations, improving work efficiency, greatly reducing human error, and ensuring the consistency of liquid during filling.

[0014] 2. This utility model achieves protection for the funnel through the cooperation of the dust cover and the groove, which solves the problem of external dust entering the funnel and ensures an effective seal between the dust cover and the funnel, greatly protecting the cleanliness of the funnel and the hygienic conditions of the culture environment.

[0015] 3. This utility model achieves uniform liquid pouring through the cooperation of the connecting rod and the guide rod, solving the problem of uneven liquid pouring each time, ensuring the uniformity of liquid pouring each time, improving the efficiency of cultivation, and simplifying the liquid pouring operation process.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-4 A multi-layer three-dimensional culture dish for rapid preparation of flat plates includes a base plate 3. A flow-diverting mechanism 1 is provided on the top of the base plate 3. The flow-diverting mechanism 1 includes a feed tube 11 bonded to the top of the base plate 3, a funnel 12 bonded to the top of the feed tube 11, a connecting rod 6 bonded inside the funnel 12, and a guide rod 7 integrally formed on one side of the connecting rod 6. The culture solution is poured into the feed tube 11 along the top of the guide rod 7. A groove 5 is formed on the top of the connecting rod 6 and the funnel 12, and a dust cover 4 is inserted into the groove 5. An anti-slip ball is bonded to the top of the dust cover 4. After the culture solution is poured in... Holding the anti-slip ball, the dust cover 4 is fixed to the top of the funnel 12 through the groove 5, which plays a role in preventing dust from entering the material tube 11 and affecting the purity of the culture medium in the next batch. Multiple guide tubes 13 are attached to one side of the material tube 11, and multiple quick-release mechanisms 2 are provided on one side of the material tube 11. The base plate 3 is made of metal, which improves the stability of the base plate 3 due to its own weight. By pouring the culture medium from the funnel 12 into the material tube 11, the shape of the funnel 12 makes it easy to pour the culture medium, avoiding the liquid splashing that is common in traditional liquid pouring.

[0023] The quick-release mechanism 2 includes a second fixing block 23 bonded to one side of the feed tube 11. The top of the second fixing block 23 has a slot 22. A first fixing block 21 is slidably connected to one side of the feed tube 11. A rod 24 is bonded to the bottom of the first fixing block 21. The rod 24 is a magnetic rod. When the rod 24 is inserted into the slot 22, it will be firmly attracted to the slot 22 due to its magnetism, forming an adsorption state. The rod 24 is inserted into the slot 22. One end of the first fixing block 21 is bonded to the culture dish body 14. Before pouring in the culture medium, the rod 24 on the first fixing block 21 is first inserted into the slot 22 in the second fixing block 23 to fix it. Then, as the culture medium is poured in, the culture medium will flow into the culture dish body 14 along the guide tube 13, realizing the quick disassembly and fixation of the culture dish body 14. The diameter of the guide tube 13 gradually decreases from top to bottom.

[0024] Working principle: When needed, before pouring in the culture medium, first insert the rod 24 on the first fixing block 21 into the slot 22 in the second fixing block 23 to fix it. Then, pour the culture medium from the funnel 12 into the feed tube 11 along the top of the guide rod 7. Due to the shape of the funnel 12 and the decreasing diameter of the guide tube 13 from top to bottom, the culture medium will flow evenly into the culture dish body 14 along the guide tube 13. After the culture medium is poured in, hold the anti-slip ball and fix the dust cover 4 to the top of the funnel 12 through the groove 5 to prevent dust.

[0025] Example 2

[0026] In this invention, the components inside the quick-release mechanism 2 are replaced by a fixing frame 25 bonded to one side of the feed tube 11. One end of the fixing frame 25 is detachably connected to a placement plate 26 by bolts. The placement plate 26 has a slot 27, and the culture dish body 14 can be inserted into the slot 27. The difference from the first embodiment is that the fixing frame 25 in the second embodiment plays the role of stabilizing and supporting the culture dish body 14, which strengthens the stability of the culture dish body 14. When the culture medium is fully cultured, the culture dish body 14 can be easily removed, which improves convenience and reduces the operating burden of the experimenter.

Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
