Description

Technical Field

[0001] This utility model relates to the field of experimental device technology, specifically to a simple bacteria scraper. Background Technology

[0002] In microbiological experiments, tools are often used to scrape bacterial growth for preparing bacterial solutions. Traditional scraping tools include small iron spoons or inoculation loops. However, when using these tools to scrape bacterial growth inside eggplant flasks, their short length makes it difficult to reach the flask if the opening is too long. To address these issues, modern technologies have proposed innovative solutions. For example, patent CN213596282U discloses a scraping device with an adjustable scraper head. While adjusting the length of the device allows it to reach the eggplant flask, sometimes a smaller scraper is needed for flasks with narrow openings. This requires a smaller scraper to reach the flask and scrape the bacterial growth. The smaller scraper scrapes too little growth each time, requiring multiple scrapings, wasting experimental time and reducing efficiency, making it unsuitable for large-scale scraping operations. In addition, if the scraping time is too long, it may increase the risk of contamination of the mycelium and affect the accuracy of subsequent experiments. Utility Model Content

[0003] This utility model provides a simple scraper to solve the problem that existing scraping devices require replacing the small scraper blade when scraping eggplant bottles with small openings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a simple scraper for scraping out inoculum cultured in a petri dish or eggplant bottle, comprising a support plate and a scraper blade, the scraper blade being used to scrape out inoculum, the scraper blade being rotatably connected to one end of the support plate, and two sets of limiting members being provided at the connection between the support plate and the scraper blade, both sets of limiting members being 180° symmetrical about the axis of symmetry of the support plate.

[0005] The limiting component includes a limiting frame, a first thin plate, and a second thin plate. The first thin plate and the second thin plate are rotatably connected. The limiting frame is set on the support plate. The second thin plate is rotatably connected to the scraper. The first thin plate is set inside the limiting frame. The limiting frame restricts the movement of the first thin plate, so that the first thin plate can only move along the length direction of the support plate.

[0006] The support plate is equipped with a fastener that can fix the first sheet to the support plate.

[0007] Furthermore, the fastener is a screw, and a through hole is provided on the first thin plate for the screw to pass through. The support plate is provided with two screw holes for the screw to fix the support plate and the first thin plate in opposite positions.

[0008] Furthermore, the first thin sheet is provided with protrusions.

[0009] Furthermore, a handle is provided at the end of the support plate away from the scraper.

[0010] Furthermore, the handle is a silicone handle.

[0011] The beneficial effects of this utility model are as follows:

[0012] The simple mycelium scraper provided by this utility model, through the setting of the support plate, allows the scraper blade to be inserted into the eggplant bottle for scraping, and can scrape off a large amount of mycelium at once, thus providing convenience for the staff to use.

[0017] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0018] like Figure 1-2 As shown, this utility model embodiment provides a simple scraper for scraping out inoculum cultured in petri dishes or eggplant bottles. It includes a support plate 1 and a scraper blade 2. The scraper blade 2 is used to scrape out inoculum. The scraper blade 2 is rotatably connected to one end of the support plate 1. Two sets of limiting members 3 are provided at the connection between the support plate 1 and the scraper blade 2. Both sets of limiting members 3 are symmetrical about the axis of symmetry of the support plate 1 by 180°.

[0019] The limiting component 3 includes a limiting frame 35, a first thin plate 31 and a second thin plate 32. The first thin plate 31 and the second thin plate 32 are rotatably connected. The limiting frame 35 is disposed on the support plate 1. The second thin plate 32 is rotatably connected to the scraper blade 2. The first thin plate 31 is disposed inside the limiting frame 35. The limiting frame 35 restricts the movement of the first thin plate 31, so that the first thin plate 31 can only move along the length direction of the support plate 1.

[0020] The support plate 1 is provided with a fastener 4 that can fix the first thin sheet 31 to the support plate 1.

[0021] Specifically, when the scraper 2 needs to be inserted into the petri dish or eggplant bottle, the fixing member 4 makes the relative position of the first thin plate 31 of the two limiting members 3 no longer fixed with respect to the support plate 1. One of the first thin plates 31 of the two limiting members 3 moves towards the scraper 2, and the other first thin plate 31 moves in the opposite direction to the scraper 2. The position of the two second thin plates 32 moves, causing the scraper 2 to rotate. After the scraper 2 is parallel to the support plate 1, it forms a retracted state. After the scraper 2 is inserted into the petri dish or eggplant bottle, the position of the first thin plate 31 is moved, and the second thin plate 32 moves, causing the scraper 2 to rotate. Then, the fixing member 4 fixes the relative position of the first thin plate 31 with respect to the support plate 1, so that the two second thin plates 32 and the scraper 2 form a relatively stable triangular structure, thereby achieving the purpose of scraping the bacteria in the bottle.

[0022] In a specific embodiment, the fastener 4 is a screw, the first thin plate 31 is provided with a through fixing hole 33 for the screw to pass through, and the support plate 1 is provided with two screw holes for the screw to fix the support plate 1 and the first thin plate 31 in opposite positions.

[0023] In order to facilitate the movement of the first sheet 31 by the staff, in a preferred embodiment of the present invention, the first sheet 31 is provided with a protrusion 34.

[0024] To enhance the anti-slip properties of the support plate 1 and prevent it from falling from the worker's hands, in a preferred embodiment of this utility model, a handle 5 is provided at the end of the support plate 1 away from the scraper 2 (in a specific embodiment, the handle 5 is a silicone handle).

[0025] In summary, this simple mushroom scraper, through the support plate, allows the scraper blade 2 to extend into the eggplant bottle for scraping, and can scrape off a larger amount of mushroom substrate at once, thus providing convenience for staff to use.

[0026] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
