Description

Technical Field

[0001] This utility model belongs to the field of sampling tools, specifically, it relates to a microbial experimental site sampling box for microbial sampling in non-laboratory environments. Background Technology

[0002] In recent years, the demand for on-site sampling for microbiological projects in the fields of food, agriculture, environment, and sanitation has surged. However, on-site microbiological sampling places extremely stringent requirements on the experimental environment, supplies, and procedures. Standards and technical specifications such as GB 4789.1-2016 "National Food Safety Standard - General Rules for Microbiological Examination of Food", GB 14934-2016 "National Food Safety Standard - Disinfection of Tableware", "Implementation Rules for National Food Safety Supervision and Sampling Inspection", GB / T 1204.3-2013 "Hygienic Inspection Methods for Public Places - Part 3: Airborne Microorganisms", GB / T 5750.2-2023 "Standard Examination Methods for Drinking Water - Part 2: Collection and Preservation of Water Samples", "Methods for Monitoring and Analysis of Water and Wastewater", HJ 91.2-2022 "Technical Specifications for Monitoring Surface Water Environmental Quality", HJ 164-2020 "Technical Specifications for Groundwater Environmental Monitoring", and GB 53-2022 "National Food Safety Standard - Examination Methods for Drinking Natural Mineral Water" all impose high requirements on on-site sampling.

[0003] However, the on-site experimental environment is complex and changeable, the experimental conditions are simple and difficult to control, and there are many external environmental pollution factors, which pose many hidden dangers: (1) In order to ensure the authenticity and accuracy of microbial experimental results, the microbial sterile laboratory has very strict requirements for cleanliness and disinfection, but the on-site sampling of microorganisms is difficult to meet the sampling environment requirements, which affects the accuracy of the sampling results. (2) The current on-site experimental tools are mostly made of wood, bamboo, composite board, etc., which are easy to hide dirt and grime and easily cause pollution to be introduced. (3) The existing sampling boxes are too simple, and the mixed placement of items is easy to cause cross-contamination.

[0004] Therefore, it is necessary to provide a field sampling box that can meet the requirements for microbial sampling. Utility Model Content

[0005] In order to overcome the problems existing in the background technology, this utility model provides a microbial experimental field sampling box, which is easy to operate, can assemble the operating table at any time, can reduce the probability of sample contamination during on-site (field) sampling, and improve sampling efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] The aforementioned microbial experimental sampling box includes a box body, a work surface, a lid, and a telescopic rod for supporting the work surface; the work surface includes a base plate and retaining rings around the base plate, with a handle on the opposite side of the retaining rings; the upper surface of the box body is a stepped surface with the inner ring lower than the outer ring, and a slot ring is formed in the inner ring of the stepped surface, into which the retaining rings of the work surface are inserted downwards; the box body and the lid are hinged by a 180-degree positioning hinge; the 180-degree positioning hinge is connected to the outside of the box body and the lid; the telescopic rod is set on the box body or the lid; a germicidal lamp is installed on the box body or the lid.

[0008] Preferably, telescopic rod holes are provided at the four corners of the upper surface of the box; the telescopic rod is set in the telescopic rod holes.

[0009] Preferably, the base plate has positioning grooves at its four corners for inserting telescopic rods.

[0010] Preferably, the telescopic rod is a ring rod, which is hinged to the inner side of the box cover by a 90-degree positioning hinge; the end of the telescopic rod is provided with a 90-degree hook.

[0011] Preferably, the inner end face of the box cover is provided with a germicidal lamp groove, and the germicidal lamp is fixed in the germicidal lamp groove.

[0012] Preferably, the box is equipped with a partition that divides the box into a sampling tool area, a disinfection tool area, a laboratory wear area, and a refrigeration area; a refrigeration box is placed in the refrigeration area; and a thermometer is placed in the refrigeration box.

[0013] As a preferred option, the box body and lid are equipped with two latches.

[0014] Preferably, an inner cover plate is also included, which is closed on the box body when the box cover is closed, and is located below the workbench surface.

[0015] Preferably, the work surface is made of stainless steel.

[0016] The beneficial effects of this utility model are:

[0017] The structure of the box body and lid of this utility model, with the box body and lid connected by a 180-degree positioning hinge, ensures that the lid is vertical after opening, forming a vertical surface that limits the stability of the workbench. By setting the workbench as a base plate with a retaining ring, it can prevent items on the workbench from rolling off during sampling operations. At the same time, the slot ring structure on the box body can neatly store the workbench inside the box, making it easy to carry and less prone to contamination.

[0018] This utility model, by setting a telescopic rod, can support the workbench and perform sampling operations on the workbench, avoiding contamination of the items inside the box during sampling. Moreover, this structure can be set up and operated anytime and anywhere, making it convenient to use and reducing the impact of the environment on the sampling work.

[0019] This invention divides the box into multiple zones by installing partitions inside the box, with different items placed in each zone. This allows for separate placement of sampling items and samples, avoiding contamination between tools and samples, facilitating zoned management, and improving the standardized operation and work efficiency of laboratory personnel in microbiological experiments.

[0020] This invention can reduce the chance of sample contamination during on-site or field sampling, and improve the quality and efficiency of sampling work. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0033] like Figure 1-6 As shown, the microbial experimental sampling box includes a box body 2, a work surface, a box cover 1, and a telescopic rod 11 for supporting the work surface.

[0034] When the box body 2 and the box cover 1 are closed, the workbench can be placed inside the sampling box to avoid contamination and facilitate carrying. When sampling, the box cover 1 is opened, the telescopic rod 11 is pulled out, the workbench is taken out and supported by the telescopic rod 11 to form an operating table, as follows:

[0035] The workbench includes a base plate 12 and a retaining ring 13 surrounding the base plate 12. To facilitate the folding of the workbench, the upper surface of the housing 2 is designed as a stepped surface with the inner ring lower than the outer ring. A slot ring 14 is formed in the inner ring of the stepped surface. The size and width of the slot ring 14 match the retaining ring 13. After sampling, the retaining ring 13 can be inserted downwards into the slot ring 14. A handle is provided on the opposite side of the base plate 12 to the retaining ring 13 (this handle is not shown in the attached drawings as it is a conventional structure for plate-like structures). The handle facilitates the removal of the workbench during use, and after the workbench is assembled, the handle is at the bottom and does not affect normal operation. Designing the upper surface of the housing as a stepped surface with the inner ring lower than the outer ring ensures that after the workbench is inserted into the slot ring 14 and folded up, it does not affect the closing of the housing 2 and the lid 1, and the workbench is less prone to contamination. The box body 2 and the box lid 1 are hinged together by a 180-degree positioning hinge. This hinge connects the outer sides of both the box body 2 and the box lid 1. When the box lid 1 is opened, it becomes vertical, forming a vertical surface that supports the workbench and increases its stability. By designing the workbench with a base plate 12 and a retaining ring 13, items on the workbench can be prevented from rolling off during sampling. As an alternative, the retaining ring 13 can be positioned on three sides around the base plate 12. After the workbench is assembled, the side without the retaining ring faces the box lid 1, which then prevents items from rolling off.

[0036] At the four corners of the upper surface of the inner ring of the stepped surface, there are telescopic rod holes. Telescopic rods 11 are installed in the telescopic rod holes. When the housing 2 and the cover 1 are closed, the telescopic rods 11 retract into the telescopic rod holes. The four corners of the base plate 12 are each provided with a positioning groove for inserting the telescopic rods 11. When it is necessary to support the work platform, the telescopic rods 11 are pulled out from the telescopic rod holes, and the four telescopic rods 11 are inserted into the four positioning grooves of the base plate 12. By setting the positioning grooves, the support stability of the work platform is increased.

[0037] To avoid the impact of the telescopic rod 11 on the workbench surface, it is best that when the telescopic rod 11 is fully retracted, it does not exceed the inner circle of the stepped surface. However, this makes it difficult to pull the telescopic rod 11 out of the telescopic rod hole. Therefore, the telescopic rod 11 can be designed so that a portion of it protrudes from the telescopic rod hole when fully retracted, making it easy for the operator to grab the telescopic rod 11 and pull it out. However, this structure requires increasing the depth of the stepped surface, i.e., increasing the height difference between the inner and outer circles of the stepped surface. Another method is to set an enlarged hole with a larger inner diameter at the top of the telescopic rod hole, so that even when the telescopic rod 11 is retracted to be flush with the inner circle, it can still be easily pulled out. The telescopic rod 11 can be any structure that can shorten and lengthen, such as a sleeve structure connected by a spring button. Regardless of the telescopic structure, it must be ensured that the four telescopic rods 11 have the same length when extended to ensure that the workbench surface can be horizontally supported.

[0038] A germicidal lamp slot 5 is provided on the inner end face of the lid 1, and a germicidal lamp 6 is fixed in the slot 5. Sampling is typically performed in places such as school / kindergarten canteens, restaurants, finished product warehouses of manufacturing enterprises, production workshops, hospitals, water intake points, rivers, lakes, and fields, where floating microorganisms may exist in the ambient air. If the environment is not disinfected, the accuracy of the sampling results will be affected. Before sampling, the lid 1 is opened and the germicidal lamp 6 is turned on to disinfect the air. During the disinfection process, the workbench covers the box, ensuring that the items inside the box are not contaminated. After disinfection, the telescopic rod 11 is pulled out and used to support the workbench for sampling. The germicidal lamp 6 can be a UV lamp or an ozone UV lamp. In addition, the disinfection lamp can also disinfect the items inside the box. During disinfection, the workbench can be removed and the lid 1 closed. The box is equipped with a partition 16, which divides the box 2 into different areas and places different items in different areas. By separating different items with the partition 16, cross-contamination between items can be prevented, and the management of items is more convenient. The specific setting of the partition 16 is determined according to the requirements. This embodiment lists two isolation methods. In actual use, this utility model is not limited to these two methods.

[0039] Method 1: As attached Figure 5 The partition 16 divides the box into a sampling tool area 17, a disinfection tool area 18, a laboratory wear area 19, and a refrigeration area 20; the refrigeration area 20 contains a refrigeration box, and the sampled samples are stored in the refrigeration box.

[0040] Method 2: Install a mounting bracket 7 at the bottom of the container 2, and fix the partition 16 inside the container 2 through the mounting bracket 7 to divide the space. The container 2 can be divided into the following sections. Figure 6 The area.

[0041] To ensure the contents of the container 2 are not contaminated, as a preferred solution, an inner cover plate 9 is also provided on the container 2. When the lid 1 is closed, the inner cover plate 9 is fitted between the inner ring of the stepped surface and the bottom plate 12. After the workbench is built, during sampling operations, the inner cover plate 9 can continue to shield the contents of the container 2, preventing contamination. The inner cover plate 9 is equipped with an inner cover handle 10. As a preferred solution, two inner cover plates 9 can be provided, each covering a different area, so that when retrieving items from different areas, the unused areas are still protected by the inner cover plate 9.

[0042] As a preferred embodiment, the base plate 12 is provided with an alcohol lamp recess 8 for placing an alcohol lamp.

[0043] As a preferred option, the box body 2 and the box cover 1 are equipped with two latches 4, each with a key. The two keys are managed by different personnel to prevent counterfeiting or sample replacement.

[0044] The work surface is made of stainless steel, which is not easily contaminated and is easier to clean and disinfect.

[0045] Although this invention cannot meet the requirements for aseptic operation, as a sampling auxiliary tool, it not only increases the convenience and efficiency of sampling work, but also provides a clean and sterile operating platform for sampling work, which can fully meet the requirements of existing testing standards for the sampling environment and reduce the risk of sample contamination. Example 2

[0046] like Figure 4-8 As shown, the difference between this embodiment and embodiment 1 is that the structure and setting position of the telescopic rod 11 are different, and no additional telescopic rod hole is provided. Everything else is the same as that in embodiment 1. This embodiment mainly explains the difference.

[0047] The telescopic rod 11 is hinged to the inner side of the lid 1 via a 90-degree positioning hinge. When the lid 1 is closed, the telescopic rod 11 is horizontal with the lid 1. When the lid 1 is open, the lid 1 is vertical, and the telescopic rod 1 is horizontal under the action of the 90-degree positioning hinge. The work platform can be placed on the telescopic rod 11 for sampling operations. To ensure the stability of the work platform, a 90-degree hook 15 is provided at the end of the telescopic rod 11, which reduces the chance of the work platform slipping off the telescopic rod 11. In addition, the telescopic rod 11 has a sleeve structure, which shortens when retracted and extends when needed. The telescopic rod 11 is not limited to a sleeve; any structure that can shorten and extend is acceptable.

[0048] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
