Description

Technical Field

[0001] The utility model relates to the technical field of microorganism detection, in particular to a microbial composite culture medium for microorganism detection. Background Technique

[0002] A culture medium is a nutrient substrate that supplies the growth and reproduction of microorganisms, plants or animal tissues, and is prepared by combining different nutrients. It is not only the basic substance that provides cell nutrition and promotes cell proliferation, but also the living environment for cell growth and reproduction. The prepared culture medium has a wide range of uses in the fields of microbiological research, medicine, food industry and environmental engineering.

[0003] The culture medium is usually made of glass, which is easy to clean, does not easily react with the components inside the culture medium, and has good light transmittance, which is convenient for observing the inside of the culture medium. The sealing generally uses a screwing structure, which is convenient and fast.

[0004] However, during the cultivation process, due to the excessive reproduction of microorganisms, simply opening the culture medium and observing from the upper end cannot understand the macroscopic growth and reproduction situation inside it, and the microorganisms will still adhere to the inner wall of the culture medium, making it more difficult for researchers to observe it. At the same time, because the culture medium uses a screwing opening method, the internal liquid of the culture medium is likely to splash out due to excessive force during the opening process. Content of the Utility Model

[0005] In view of the problems that the attachments on the inner wall are not conducive to observation and the culture medium is easy to splash out when opened, the present utility model is proposed.

[0006] To solve the above technical problems, the present utility model provides the following technical solution: A microbial composite culture medium for microorganism detection, including a culture medium, wherein sliding cover grooves are opened on both sides at the top of the culture medium, a sliding cover is movably connected in the sliding cover grooves, a pulling plate is fixedly connected to the rear end of the sliding cover, and the pulling plate is hermetically installed in a fitting opening;

[0007] A rotating shaft is arranged at the lower end of the sliding cover, the rotating shaft is movably connected to one end of a rocker, a baffle is installed on one side of the rotating shaft, the baffle blocks the rocker from moving towards the pulling plate side, a connecting rod is installed on the side of the rocker away from the rotating shaft, and a scraping plate is tightly connected to the end of the connecting rod away from the rocker.

[0008] Preferably, the rocker, the connecting rod and the scraping plate are connected in a Z shape, and the scraping plate fits with both sides of the culture medium.

[0009] Preferably, the width of the fitting opening is greater than the thickness of the rotating shaft and the scraping plate.

[0010] Preferably, a pressing plate is fixedly installed at the upper end of the sliding cover. A clamping opening is formed at the upper end of the pressing plate. An activity groove is formed between the pressing plate and the sliding cover, and the pressing plate can be pressed into the activity groove.

[0011] Preferably, a buckle is installed at one end of the culture medium away from the fitting opening. The buckle extends to the upper end of the sliding cover and can form an embedded connection with the clamping opening.

[0012] Preferably, a sealing strip is built between the sliding cover groove and the sliding cover. A sealing pad is adhered to the inner side wall of one end of the culture medium away from the fitting opening. The sealing strip and the sealing pad can be hermetically connected to the sliding cover. A through hole is formed at the upper end of the sliding cover, and a piston is embedded therein.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the scraper connected by the rotating shaft at the lower end of the sliding cover is positioned by the baffle, so that the scraper will be drawn out together when the sliding cover is drawn out. When there is too much floating matter in the culture medium and it is impossible to observe the internal situation by opening the sliding cover, just push the sliding cover to close, and the scraper will be blocked by the baffle, so that it scrapes the attachments on both sides of the culture medium, and then the internal situation can be observed.

[0015] 2. At the same time, the sliding cover movably connected in the sealing strip enables the device to be opened and closed in a drawable manner, and is clamped and connected to the pressing plate at the upper end of the sliding cover through the buckle, so that the liquid in the device is not easy to splash out, and the opening and closing are convenient.

Specific implementation mode

[0024] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the specific implementation mode of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0025] Embodiment 1

[0026] Referring to Figures 1-5 , which is the first embodiment of the present utility model, a microbial composite culture medium for microbial detection is provided, including a culture medium 1. Sliding cover grooves 2 are opened on both sides of the top end of the culture medium 1. Sealing strips 4 are adhered to the left and right inner sides of the sliding cover grooves 2. A sliding cover 3 is movably connected to the inner side of the sealing strip 4. As Figure 4 shown, the sliding cover 3 can perform a pulling movement therein. At the same time, a pulling plate 13 is fixedly connected to the rear end of the sliding cover 3. The pulling plate 13 can be hermetically installed in the fitting opening 16 to form a complete seal, so that no bacteria can enter.

[0027] A rotating shaft 7 is installed at the lower end of the sliding cover 3. The rotating shaft 7 is movably connected to one end of a rocker 8 and can swing left and right. A baffle 9 is fixedly installed on one side of the rotating shaft 7. The baffle 9 blocks the rocker 8 from moving towards the pulling plate 13 side, so that it can only move towards the pressing plate 5 side until it abuts against the sliding cover 3. A connecting rod 10 is installed on the side of the rocker 8 away from the rotating shaft 7. A scraper 11 is fixedly installed at the end of the connecting rod 10 away from the rocker 8.

[0028] The rocker 8, the connecting rod 10, and the scraper 11 are connected in a turning manner to form a shape similar to a Z shape, and the scraper 11 is attached to both sides of the inner wall of the culture medium 1, so that when the scraper 11 moves, it can produce a scraping effect with the inside of the culture medium 1.

[0029] The width of the fitting opening 16 is greater than the thickness of the rotating shaft 7 and the scraper 11, so that the rotating shaft 7 and the scraper 11 can be separated from the culture medium 1 along with the sliding cover 3 through the fitting opening 16.

[0030] During use, the culture medium 1 is made of transparent material, and the sliding cover 3 is installed into the sliding cover groove 2 along the fitting opening 16. At the same time, the width of the fitting opening 16 is greater than the thickness of the rotating shaft 7 and the scraper 11, so the scraper 11 is also rotated to the right through the rotating shaft 7 to fit to the bottom of the sliding cover, and is placed inside the culture medium 1 through the fitting opening 16. The scraper 11 fits to both sides of the inner wall of the culture medium 1 by default, and can generate friction with the inside of the culture medium to achieve a scratchable effect. When it is necessary to open the device to configure the culture solution or take a sample, the sliding cover 3 is pulled outward. Since the scraper 11 is fixedly connected to the connecting rod 10, the connecting rod 10 is fixedly connected to the rocker 8, and the rocker 8 is movably connected to the sliding cover 3 through the rotating shaft 7, when the scraper 11 is driven and dragged outward by the sliding cover 3, the scraper 11 will be lifted to the right due to the friction, and can also be dragged out of the culture medium 1 along with the sliding cover 3, which is convenient for disassembly and cleaning;

[0031] On the contrary, when the device needs to be closed, the sliding cover 3 is pushed inward, and the scraper 11 is driven to rub to the left. Due to the baffle 9, the scraper 11 will not be lifted upward as when the sliding cover 3 is pulled out, but will be blocked in place by the baffle 9, making it unable to move to one side. Therefore, when the sliding cover 3 is pushed inward, the scraper 11 also scrapes the inner wall at the same time, so that the attachments on both sides of the inner wall of the culture medium 1 are scraped off, so that the internal situation of the culture medium 1 can be clearly observed.

[0032] Example 2

[0033] Reference Figures 1-5 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that a pressing plate 5 is fixedly installed on the upper end of the sliding cover 3, and a movable groove 12 is opened between the front end of the pressing plate 5 and the sliding cover 3. The pressing plate 5 is made of a bendable and resilient material, so the pressing plate 5 can be pressed into the movable groove 12.

[0034] A buckle 6 is installed at one end of the culture medium 1 away from the fitting opening 16 . The buckle 6 is configured to extend to the upper end of the sliding cover 3 so that the buckle 6 is hooked into the inner groove of the fitting opening 17 to achieve a positive connection with the fitting opening 17 .

[0035] A sealing strip 4 is built between the sliding cover groove 2 and the sliding cover 3, and a sealing gasket 15 is adhered to the inner wall of the end of the culture medium 1 away from the fitting opening 16. The sealing strip 4 and the sealing gasket 15 can be sealed and connected to the sliding cover 3 to prevent bacteria from flowing in. A through hole is opened at the upper end of the sliding cover 3, in which a piston 14 is embedded for sampling.

[0036] During use, when the device needs to be closed, the sliding cover 3 is pushed inward. When the sliding cover 3 is pushed a certain distance, the pressing plate 5 at the upper end of the sliding cover 3 will be blocked by the buckle 6 connected to the culture medium 1. Since the pressing plate 5 is made of a bendable and resilient material, the pressing plate 5 can be pressed downward and bent. When a part of the pressing plate 5 falls into the movable groove 12, the sliding cover 3 is further pushed forward to the lower end of the engaging port 17. At the same time, the sliding cover 3 will be pushed to the push sealing gasket 15 and is hermetically connected to it. Stop pressing the pressing plate 5, so that the buckle 6 is engaged in the engaging port 17 to complete the snap connection. At the same time, the pull plate 13 and the sealing strips 4 on both sides of the sliding cover 3 form a sealing structure. The pull plate 13 is embedded in the fitting port 16, making the whole device in a completely sealed state. The whole opening and closing is convenient and fast, and the sealing performance is good.

[0037] At the same time, a debugging hole is provided at the upper end of the sliding cover 3, and a piston 14 is hermetically connected in the debugging hole. When only part of the sample needs to be taken out, the piston 14 can be opened to complete the sampling and reduce the entry of bacteria.

[0038] The rest of the structure is the same as that of Embodiment 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
