Abstract
Description
Technical Field
[0001] This utility model relates to the field of edible fungi cultivation technology, and in particular to a device for placing slant culture media in the laboratory. Background Technology
[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.
[0003] In the production of edible fungi spawn, it is often necessary to prepare a large number of test tube slant culture media for spawn cultivation, preservation and testing. The traditional method of preparing slant culture media is to bundle test tubes together in groups of 7 to 10, wrap one end of the test tube with sulfuric acid paper or kraft paper, sterilize them under high pressure, place a wooden strip or board about 1 to 2 cm thick on the laboratory table, and place the test tube head on the wooden strip or board to allow the culture medium in the test tube to tilt naturally. After standing and solidifying, the slant culture medium is obtained.
[0004] However, this method has significant drawbacks: (1) it is cumbersome to operate, requiring manual adjustment of the test tube angle and is prone to slipping; (2) the wooden strip support makes the slope angle uncontrollable, resulting in uneven slope size; (3) the test tube stopper is prone to sticking to the culture medium, posing a high risk of contamination; and (4) it lacks standardized equipment, resulting in poor reproducibility. The above problems seriously restrict experimental efficiency and strain quality.
[0005] To address the shortcomings of existing technologies, publicly available solutions, such as patent CN216614596U, propose a slanted culture medium placement device, which uses a tray and an adjustable nut to form a slanted structure. However, this solution still has the following problems: (1) the tray is bulky and inconvenient to store; (2) the threaded nut adjustment structure is prone to loosening, resulting in poor slope stability; (3) the limiting groove lacks adaptability and cannot be compatible with test tubes of different specifications. Utility Model Content
[0006] To address the shortcomings of existing technologies, this invention provides a device for placing slant culture media in the laboratory. It features a compact structure, precise adjustment, and strong adaptability, thus solving one or more technical problems existing in the prior art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A device for placing laboratory slant culture media includes a first base plate, a second base plate, and a baffle. One end of the first base plate is fixedly connected to the baffle, and the other end is hinged to the second base plate. The upper surface of the second base plate is provided with a plurality of test tube limiting grooves.
[0009] Furthermore, the bottom upper side, left side and right side of the first base plate are provided with dovetail tenon splicing structures.
[0010] Furthermore, the hinge includes a straight alloy sheet and an L-shaped alloy sheet, the straight alloy sheet being fixedly connected to the second base plate, and the L-shaped alloy sheet being fixedly connected to the first base plate.
[0011] Furthermore, a hand-tightened wing screw is provided at the connection between the straight alloy sheet and the L-shaped alloy sheet for adjusting the tightness of the structure.
[0012] Furthermore, the width of the test tube limiting groove is equal to the diameter of the test tube.
[0013] Furthermore, the inner surface of the test tube limiting groove has an arc-shaped groove structure.
[0014] Furthermore, the second base plate has an arc-shaped edge near the hinge, and the arc-shaped edge is coaxial with the rotation axis of the hinge.
[0015] Furthermore, the baffle is perpendicular to the upper surface of the first base plate.
[0016] Furthermore, the first base plate and the second base plate have the same thickness and are both rectangular flat plate structures.
[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model connects the first base plate and the second base plate with a hinge. The device can be folded into a plate-like structure. When not in use, the first and second base plates are connected by a rotatable hinge, which is basically a plate-like structure, taking up little space and making it easy to store. The dovetail joint structure enables multiple devices to be tightly spliced, improving the overall stability and solving the problems of inconvenient storage of traditional devices and loose splicing of existing patents.
[0019] 2. In this utility model, the hinge is composed of a straight alloy sheet and an L-shaped alloy sheet, which, together with the hand-tightened wing screw, enables flexible adjustment and rigid fixation of the rotation angle of the second base plate, ensuring a consistent slope angle and overcoming the defects of uncontrollable wooden strip support angle and loose threaded nut structure.
[0020] 3. This utility model designs the inner surface of the test tube limiting groove as an arc-shaped groove structure, which effectively prevents the test tube from slipping; the groove width is designed to be 18mm or 20mm, which is compatible with the two test tube specifications commonly used to make slant culture media: 18×180mm and 20×200mm, thus solving the problem of poor versatility of the limiting groove in the existing device.
[0021] 4. This utility model adopts rectangular flat plates of equal thickness for the first base plate and the second base plate. The arc-shaped edge at the end of the second base plate is designed to be coaxial with the hinge to ensure smooth rotation. The overall structure is lightweight and reliable, simplifies the operation process, and improves experimental efficiency. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] Example 1
[0032] A typical embodiment of this utility model is as follows: Figure 1As shown, a device for placing slant culture media in the laboratory includes a first base plate 1, a second base plate 2, and a baffle 3. One end of the first base plate 1 is fixedly connected to the baffle 3, and the other end is hinged to the second base plate 2 via a hinge 5 to enable the second base plate to rotate, thereby adjusting the slope. The upper surface of the second base plate 2 is provided with multiple test tube limiting grooves 4, which increases the friction between the test tubes and the device, making them less likely to slip.
[0033] Specifically, the length, width, and height of the first base plate are 25cm, 15cm, and 1cm, respectively, and the length, width, and height of the second base plate are 25cm, 10cm, and 1cm, respectively.
[0034] This device for placing slant culture media in the laboratory has a simple structure and ingenious design. Through the cooperation of the first base plate, the second base plate and the baffle, it achieves stable placement of test tube slant culture media, and the slope can be easily adjusted and the operation is simple.
[0035] like Figure 2 As shown, the bottom upper, left and right sides of the first base plate 1 are provided with dovetail tenon splicing structures 6. The dovetail tenon splicing structures 6 expand the area for placing inclined culture medium, and the tenon and mortise structure is tightly connected, which can realize the splicing of various inclined culture medium placement devices and increase the overall stability of the structure.
[0036] Hinge 5 includes a straight alloy sheet and an L-shaped alloy sheet. The straight alloy sheet is fixedly connected to the second base plate 2, and the L-shaped alloy sheet is fixedly connected to the first base plate 1.
[0037] like Figure 3 As shown, a hand-tightened wing screw 7 is provided at the connection between the straight alloy sheet and the L-shaped alloy sheet. In other words, the hand-tightened wing screw 7 passes through the connection hole between the straight alloy sheet and the L-shaped alloy sheet, and is used to adjust the tightness of the structure to achieve precise control of the slope angle. The hinge 5 uses a hand-tightened wing screw 7, which facilitates the assembly and disassembly of the device and occupies little space. At the same time, the cooperation between the hinge and the hand-tightened wing screw allows for precise control of the rotation angle of the second base plate, thereby realizing slope adjustment during the preparation of the inclined culture medium and ensuring the consistency of the slope size.
[0038] The width of the test tube retaining groove 4 is equal to the diameter of the test tube. In one embodiment, the width of the test tube retaining groove 4 is 18mm or 20mm, respectively adaptable to the two most commonly used test tube sizes of 18×180 and 20×200 units / mm for preparing slant culture media in the laboratory. The test tube retaining groove ensures that the test tube can be firmly placed on the second base plate, avoiding the problem of the test tube slipping. At the same time, the width of the test tube retaining groove is adapted to commonly used test tube sizes, making it highly practical.
[0039] The inner surface of the test tube limiting groove 4 has an arc-shaped groove structure, and the material of the test tube limiting groove 4 is anti-slip rubber. The arc-shaped groove structure and anti-slip rubber material on the inner surface of the test tube limiting groove increase the friction between the test tube and the limiting groove, preventing the test tube from sliding during placement.
[0040] The second base plate 2 has a rounded edge near the hinge 5, and this rounded edge is coaxial with the rotation axis of the hinge 5. This rounded edge design near the hinge of the second base plate makes the rotation of the second base plate smoother and avoids problems such as jamming or damage.
[0041] The baffle 3 is perpendicular to the upper surface of the first base plate 1. The height of the baffle 3 is 20-25mm. It can effectively prevent the test tubes from slipping off the first base plate, and will not affect the placement and removal of the test tubes.
[0042] The first base plate 1 and the second base plate 2 have the same thickness and are both rectangular flat plate structures, which makes the entire placement device more stable and reliable, and able to withstand greater weight and pressure.
[0043] Working principle
[0044] When using the device, choose a flat and stable work surface or floor to ensure stability. Next, use the hand-tightening wing screws 7 on the second base plate 2 to rotate it to the appropriate working angle according to experimental requirements. Then, place the test tube in the working area of the device, ensuring the bottom of the test tube is tightly against one side of the anti-slip baffle. Finally, securely insert the upper opening of the test tube into the arc-shaped groove of the test tube limiting groove 4. The clamping action of the limiting structure firmly fixes the test tube, effectively preventing it from sliding or falling off while waiting for the culture medium to cool. Throughout the entire operation, it is important to maintain the stability of the device and ensure the test tube is tilted for optimal results.
[0045] In the description of this specification, the terms "connection", "installation", "fixing", "setting", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
