Description

Microbial counting device Technical Field

[0001] This utility model relates to the field of biological experimental equipment technology, and in particular to a microbial counting device. Background Technology

[0002] In microbiological experiments, it is often necessary to count the number of colonies cultured in glassware to obtain accurate experimental data. Typically, researchers use a microbial counting device to assist in this counting process. One existing microbial counting device includes a working platform and a placement tank set on the platform. The glassware is placed in the placement tank, and a light is installed below the tank to illuminate the glassware so that the operator can clearly see the colonies inside.

[0003] Existing microbial counting devices have the following shortcomings: Operators need to count all colonies in the dish in one go to avoid confusing pre- and post-counting colonies. Therefore, operators need to face the brightly lit dishes for extended periods, easily causing eye fatigue. Furthermore, laboratory dishes vary in size, and to improve the versatility of the placement tank, its size is often designed based on the largest dish size. This allows smaller dishes to easily move within the tank, interfering with the operator's counting process. Additionally, tiny colonies are difficult for operators to see, increasing the difficulty of counting. Summary of the Invention

[0004] The purpose of this invention is to provide a microbial counting device that can reduce the difficulty of counting operations, alleviate eye fatigue for operators, and achieve high counting accuracy.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A microbial counting device is provided, comprising:

[0007] The cabinet has a work platform on its top, and the work platform is provided with an observation hole for communicating with the interior of the cabinet.

[0008] A transparent mirror is installed inside the observation hole. The transparent mirror is provided with crisscrossing dividing lines so that the transparent mirror is divided into several counting areas by the dividing lines.

The two clamps are used to clamp the utensils.

[0011] Furthermore, each of the two clamping plates has a groove on its opposite side for accommodating the vessel.

[0012] Furthermore, it also includes a support assembly, which includes a column, a base, and a mounting component. The base is vertically and flexibly mounted on the column. One end of the mounting component is rotatably connected to the base, and the other end of the mounting component is fitted with the magnifying glass.

[0013] Furthermore, it also includes a flexible metal threaded bracket, one end of which is connected to the cabinet and the other end of which is connected to the magnifying glass.

[0014] Furthermore, the elastic structure includes an outer sleeve, an inner sleeve, and a spring. One end of the outer sleeve is connected and fixed to the frame, and one end of the inner sleeve is connected and fixed to the clamping plate. The end of the inner sleeve facing away from the clamping plate is inserted into the outer sleeve, and the inner sleeve and the frame are elastically connected by the spring.

[0029] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] As shown in Figures 1 to 3, the microbial counting device provided by this utility model includes a cabinet 1, a transparent mirror 2, a magnifying glass 4, and a support component 5. The cabinet 1 has a rectangular parallelepiped structure, providing overall support. The transparent mirror 2, magnifying glass 4, and support component 5 are all mounted on the cabinet 1. The cabinet 1 has a hollow structure, forming an internal cavity. A working platform 11 is formed on the top of the cabinet 1, where the experimenter performs counting operations. The side of the cabinet 1 facing the experimenter is the front side 14. An observation hole 12 is provided on the working platform 11, and the internal cavity of the cabinet 1 communicates with the outside of the cabinet 1 through the observation hole 12. The transparent mirror 2 is made of transparent glass, and its shape matches the shape of the observation hole 12. In this embodiment, both the transparent mirror 2 and the observation hole 12 are circular. The transparent mirror 2 is installed inside the observation hole 12 and completely covers it, allowing the experimenter to observe the interior of the cabinet 1 through the transparent mirror 2. The transparent mirror 2 is provided with crisscrossing dividing lines 21, which divide the transparent mirror 2 into several counting areas 22. The magnifying glass 4 is movably mounted on the working platform 11, and can be selectively moved above the transparent mirror 2. The support assembly 5 is used to place the container containing colonies. The support assembly 5 is inserted into the cabinet 1 and includes a frame 51, clamps 52, and an elastic structure 53. There are two clamps 52, which are spaced apart horizontally and are elastically connected to the frame 51 by the elastic structure 53. The two clamps 52 are spaced apart, forming a gap for placing the container. During the counting operation, the container is placed between the two clamps 52, and under the elastic force of the elastic structure 53, the two clamps 52 clamp the container, and the container is located directly below the observation hole 12.

[0031] Understandably, during counting, the container with cultured colonies is placed between two clamps 52, which hold the container in place. This structure is suitable not only for containers of various sizes but also utilizes the elastic structure 53 to clamp the container, preventing movement and thus avoiding interference with the counting process. A transparent mirror 2 is installed inside the observation hole 12 to protect the container, preventing external debris from falling in and airflow from the external environment from moving the bacterial colonies, thereby avoiding interference with the counting process. The transparent mirror 2 has dividing lines 21, allowing the counting personnel to count colonies in corresponding areas of the container one by one through the counting area 22, preventing confusion during counting. The counting area 22 allows the personnel to count colonies in different areas of the container multiple times, reducing eye strain. Furthermore, when the colonies in the container are small, a magnifying glass 4 can be moved above the transparent mirror 2 to magnify the colonies, making them easier to see and reducing the difficulty of counting.

[0032] Specifically, the overall structure of the support component 5 is similar to that of a drawer in the prior art. The support component 5 is inserted into the cabinet 1 from the front side 14. The frame 51 is a square frame structure, with its opposite ends extending through the cabinet 1 along its height. Two clamping plates 52 are respectively installed on the two opposite inner side walls of the frame 51. Each clamping plate 52 has two elastic structures 53 spaced apart, allowing the clamping plate 52 to be elastically connected to the frame 51 through the elastic structures 53. Each of the two clamping plates 52 has a groove 521 on its opposite side, which is used to accommodate a vessel. The grooves 521 on the two clamping plates 52 form an installation space for accommodating the vessel. The installation space is located directly below the observation hole 12, allowing the experimenter to see the vessel below through the observation hole 12. To facilitate the placement of the vessel, the end of the clamping plate 52 facing the front side 14 of the cabinet 1 is rounded, allowing the vessel to enter the installation space along the arc surface of the end of the clamping plate 52.

[0033] A notch 511 is provided at the end of the frame 51 facing the outside of the cabinet 1, and the notch 511 and the clamping plate 52 are located on the same horizontal plane. When placing the vessel, the vessel moves horizontally through the installation space between the two clamping plates 52 via the notch 511. This structure can prevent interference between the vessel and the frame 51 when placing the vessel. The notch 511 is located at the top of the frame 51. This structure allows the vessel to be placed closer to the observation hole 12 and facilitates operation during placement. A handle 55 is provided at the end of the frame 51 facing the front side 14, and the handle 55 is located below the notch 511. When placing and removing the vessel, the experimenter can use the handle 55 to pull out the supporting component 5.

[0034] Slide rails 54 are provided on both opposite sides of the frame 51. Correspondingly, rollers are provided on the cabinet 1 to slide in cooperation with the slide rails 54, so that the frame 51 can be slidably connected to the cabinet 1 through the slide rails 54 and the rollers. In this embodiment, the motion mechanism composed of the slide rails 54 and the rollers is the same as that of the drawer in the prior art, so as to realize the pull-out function of the supporting component 5 on the cabinet 1. Its specific structure and working principle will not be described in detail here.

[0035] Specifically, referring to Figure 4, the elastic structure 53 includes an outer sleeve 531, an inner sleeve 532, and a spring 533. Both the outer sleeve 531 and the inner sleeve 532 are hollow cylindrical structures with different diameters. In this embodiment, the inner diameter of the outer sleeve 531 is equal to the outer diameter of the inner sleeve 532. One end of the inner sleeve 532 is inserted into the outer sleeve 531 and can slide axially along the outer sleeve 531. One end of the outer sleeve 531 is fixedly connected to the inner wall of the frame 51, and the inner sleeve 532 is inserted into the other end of the outer sleeve 531. One end of the inner sleeve 532 is fixedly connected to the clamping plate 52, and the other end is inserted into the outer sleeve 531. Furthermore, the end of the inner sleeve 532 facing away from the clamping plate 52 is elastically connected to the frame 51 via the spring 533. The structure uses the inner sleeve 532 and the outer sleeve 531 to support the clamping plate 52, while the spring 533 applies elastic force to the clamping plate 52 in the horizontal direction to clamp the vessel.

[0036] Specifically, referring to Figure 1, the microbial counting device also includes a support assembly 3 for mounting the magnifying glass 4. The support assembly 3 includes a column 31, a base 33, and a mounting element 34. The column 31 is mounted on the working platform 11 and is close to the observation hole 12. The base 33 is fitted onto the column 31 and can move up and down on the column 31. Several limiting teeth 32 are provided on the side wall of the column 31, all arranged vertically in sequence. Correspondingly, the base 33 is provided with an elastic buckle that can engage between two adjacent limiting teeth 32. It is understood that the limiting teeth 32 and the elastic buckle are existing technologies, and the limiting teeth 32 and the elastic buckle achieve the limiting and fixing of the base 33 on the column 31. When the height of the base 33 needs to be adjusted, the experimenter can press the elastic buckle and then slide the base 33 to the appropriate position. Mounting element 34 is fitted around the periphery of base 33 and rotatably connected to base 33. Magnifying glass 4 is mounted on the end of mounting element 34 facing away from base 33. During counting operations, when magnifying glass 4 is needed, simply rotate mounting element 34 to move magnifying glass 4 above observation hole 12. When adjusting the height of magnifying glass 4, press the elastic buckle and slide base 33 to the appropriate position.

[0037] In another embodiment, the microbial counting device further includes a flexible metal threaded support. One end of the metal threaded support is fixedly connected to the cabinet 1, and the other end is fixedly connected to the magnifying glass 4. The metal threaded support is prior art; it is made of a long strip of metal material and has a certain rigidity, providing sufficient support for the magnifying glass 4. Simultaneously, the experimenter can freely bend the metal threaded support to move the magnifying glass 4 to a suitable position for convenient use.

[0038] Specifically, the work platform 11 is provided with multiple observation holes 12. Correspondingly, each observation hole 12 is provided with a support component 5 to facilitate the simultaneous counting of multiple containers.

[0039] Specifically, a lighting lamp (not shown in the figure) and an ultraviolet lamp (not shown in the figure) are installed inside the cavity of cabinet 1. The lighting lamp is located below the support component 5. It should be noted that the glassware is made of transparent glass. The lighting lamp is used to illuminate the glassware so that the experimenter can observe and count it. The ultraviolet lamp is installed inside the cavity of cabinet 1. After counting is completed, the ultraviolet lamp can be turned on to sterilize the support component 5. Correspondingly, a switch component 13 is provided on the front side 14 of cabinet 1. The switch component 13 is electrically connected to the lighting lamp and the ultraviolet lamp to control the start and stop of the lighting lamp and the ultraviolet lamp.

[0040] In this embodiment, the microbial counting device is used as follows: First, remove the support component 5 and insert the container with cultured colonies between the two clamps 52 through the notch 511. Under the action of the elastic structure 53, the two clamps 52 clamp the container tightly. Then, insert the support component 5 into the cabinet 1. At this time, the container is located below the observation hole 12. Second, turn on the light to illuminate the container. Third, the experimenter observes and counts the colonies in the container through the transparent lens 2. When the colonies are small, the mounting part 34 can be rotated and the height of the base 33 can be adjusted to move the magnifying glass 4 above the transparent lens 2, so that the experimenter can clearly observe the colonies. Fourth, after counting, remove the container and turn on the ultraviolet lamp for sterilization.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
