Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and in particular to a sampling device for detecting pathogenic bacteria in food. Background Technology

[0002] Pathogenic bacteria are microorganisms that can cause disease. They are also known as pathogenic microorganisms and include bacteria, viruses, spirochetes, rickettsiae, chlamydiae, mycoplasma, fungi, and actinomycetes.

[0003] Some liquid foods are prone to contamination by pathogens during processing due to substandard hygiene or improper handling. To ensure food safety, it is necessary to test for pathogens in food. This requires sampling devices to collect samples from liquid foods. When sampling liquids, pipettes or other suction devices are generally used. However, when the liquid in the sampling tube is discharged onto the observation dish, it is impossible to control the discharge volume, resulting in low accuracy of the test and causing inconvenience in subsequent testing. Utility Model Content

[0004] In view of the above problems, this application provides a sampling device for detecting pathogenic bacteria in food, which solves the technical problem of being unable to accurately control the amount of sample taken and discharged.

[0005] To achieve the above objectives, the inventors provide a sampling device for detecting pathogenic bacteria in food, comprising:

[0006] Fixed cylinder;

[0007] A connecting rod, one end of which is located inside the fixed cylinder;

[0008] A needle, which is fixed to the bottom of the fixed cylinder and is connected to the fixed cylinder;

[0009] An extrusion plate, the top of which is fixed to the bottom of the connecting rod, is located inside the fixed cylinder and is slidably connected to the inner wall of the fixed cylinder;

[0010] Top plate, the bottom of which is fixedly connected to the top of the connecting rod; and

[0011] Rubber blocks, multiple rubber blocks are fixed to the inner wall of the fixed cylinder at equal intervals.

[0012] Unlike existing technologies, the technical solution of this application has a connecting rod with one end located inside the fixed cylinder, a needle fixed to the bottom of the fixed cylinder and connected to the fixed cylinder, a top of the extrusion plate fixed to the bottom of the connecting rod, the extrusion plate located inside the fixed cylinder and slidably connected to the inner wall of the fixed cylinder, a bottom of the top plate fixed to the top of the connecting rod, and multiple rubber blocks fixed to the inner wall of the fixed cylinder at equal intervals. In this way, the cooperation between the rubber blocks and the pressure plate can prevent the extrusion plate from moving, thereby achieving the effect of quantitative sampling and quantitative sorting.

[0013] In one embodiment of this utility model, the sampling device further includes a cavity, a fixing rod, a through hole, and an elastic element. The cavity is formed on one side of the fixing cylinder, the fixing rod is located inside the cavity, one end of the elastic element is fixed to one side wall of the cavity, and the other end of the elastic element is fixed to one side of the fixing rod. The through hole is formed in the fixing cylinder, and the cavity is connected to the inside of the fixing cylinder through the through hole. One end of the rubber block passes through the through hole and is fixed to the side of the fixing rod. The side of the rubber block is pressed against the inner wall of the through hole.

[0014] In this way, the elastic element and the fixed rod work together to facilitate the compression of the rubber block by the extrusion plate, thereby reducing the resistance of the rubber block to the extrusion plate.

[0015] In one embodiment of this utility model, the sampling device further includes a bolt, a threaded hole, an annular plate, and an L-shaped connecting rod. The fixed cylinder has the threaded hole, and the cavity is connected to the outside of the fixed cylinder through the through hole. The output end of the bolt passes through the threaded hole and is threadedly connected to the threaded hole. The inner wall of the annular plate is fixed to the output end of the bolt. One end of the L-shaped connecting rod is fixed to the side of the fixed rod near the elastic element, and the other end of the L-shaped connecting rod is located on the side of the annular plate away from the fixed rod.

[0016] Thus, through the cooperation of the annular plate and the L-shaped connecting rod, the position of the fixing rod can be controlled by the action of the bolts, thereby adjusting the position of the rubber block, which facilitates the sampling and arrangement of the device.

[0017] In one embodiment of this utility model, there are two L-shaped connecting rods that are symmetrical about the annular plate.

[0018] In this way, the stability of the fixed rod can be improved through the action of the two L-shaped connecting rods.

[0019] In one embodiment of this utility model, the portion of the rubber block located inside the fixed cylinder is a hemisphere.

[0020] This facilitates the compression of the rubber block by the extrusion plate.

[0021] In one embodiment of this utility model, the sampling device further includes a rubber pad, and the rubber pad is provided on the outside of the extrusion plate.

[0022] In this way, the rubber gasket improves the sealing between the extrusion plate and the inner wall of the fixed cylinder.

[0023] In one embodiment of this utility model, the connection between the side of the rubber pad near the rubber block and the bottom of the rubber pad is arc-shaped.

[0024] This facilitates the compression of the rubber block by the rubber pad.

[0056] Currently, liquid sampling is generally performed using suction devices such as pipettes. When the liquid in the sampling tube is discharged onto the observation dish, the discharge volume cannot be controlled, resulting in low detection accuracy and causing inconvenience in subsequent testing processes.

[0057] According to some embodiments of this application, please refer to Figures 1 to 3 This embodiment relates to a sampling device for detecting pathogenic bacteria in food, including a fixed cylinder 1, a connecting rod 2, a needle 3, a squeezing plate 4, a top plate 5, and rubber blocks 6. One end of the connecting rod 2 is located inside the fixed cylinder 1. The needle 3 is fixed to the bottom of the fixed cylinder 1 and is connected to the fixed cylinder 1. The top of the squeezing plate 4 is fixed to the bottom of the connecting rod 2. The squeezing plate 4 is located inside the fixed cylinder 1 and is slidably connected to the inner wall of the fixed cylinder 1. The bottom of the top plate 5 is fixed to the top of the connecting rod 2. A plurality of rubber blocks 6 are fixed to the inner wall of the fixed cylinder 1 at equal intervals.

[0058] Unlike existing technologies, the technical solution of this application has a connecting rod 2 located inside the fixed cylinder 1 at one end, a needle 3 fixedly connected to the bottom of the fixed cylinder 1 and interconnected with the fixed cylinder 1, a squeezing plate 4 fixedly connected to the bottom of the connecting rod 2 at the top, the squeezing plate 4 located inside the fixed cylinder 1 and slidably connected to the inner wall of the fixed cylinder 1, a top plate 5 fixedly connected to the top of the connecting rod 2 at the bottom, and multiple rubber blocks 6 fixedly connected to the inner wall of the fixed cylinder 1 at equal intervals. In this way, the cooperation between the rubber blocks 6 and the pressure plate can achieve the effect of blocking the movement of the squeezing plate 4, thereby achieving the effect of quantitative sampling and quantitative sorting.

[0059] According to some embodiments of this application, optionally, the sampling device further includes a cavity 7, a fixing rod 8, a through hole 9, and an elastic element 15. The cavity 7 is provided on one side of the fixing cylinder 1, the fixing rod 8 is located inside the cavity 7, one end of the elastic element 15 is fixed to one side wall of the cavity 7, and the other end of the elastic element 15 is fixed to one side of the fixing rod 8. The through hole 9 is provided in the fixing cylinder 1, and the cavity 7 is connected to the interior of the fixing cylinder 1 through the through hole 9. One end of the rubber block 6 passes through the through hole 9 and is fixed to the side of the fixing rod 8. The side of the rubber block 6 is pressed against the inner wall of the through hole 9.

[0060] Thus, through the action of the elastic element 15 and the fixing rod 8, the extrusion plate 4 can extrude the rubber block 6, thereby reducing the resistance of the rubber block 6 to the extrusion plate 4.

[0061] According to some embodiments of this application, optionally, the sampling device further includes a bolt 10, a threaded hole 11, an annular plate 12, and an L-shaped connecting rod 13. The fixed cylinder 1 has the threaded hole 11. The cavity 7 is connected to the outside of the fixed cylinder 1 through the through hole 9. The output end of the bolt 10 passes through the threaded hole 11 and is threadedly connected to the threaded hole 11. The inner wall of the annular plate 12 is fixed to the output end of the bolt 10. One end of the L-shaped connecting rod 13 is fixed to the side of the fixed rod 8 near the elastic member 15, and the other end of the L-shaped connecting rod 13 is located on the side of the annular plate 12 away from the fixed rod 8.

[0062] Thus, through the cooperation of the annular plate 12 and the L-shaped connecting rod 13, the position of the fixing rod 8 can be controlled by the action of the bolt 10, thereby adjusting the position of the rubber block 6, which facilitates the sampling and arrangement of the device.

[0063] According to some embodiments of this application, optionally, two L-shaped connecting rods 13 are provided and are symmetrical about the annular plate 12.

[0064] Thus, the stability of the fixed rod 8 can be improved through the action of the two L-shaped connecting rods 13.

[0065] According to some embodiments of this application, optionally, the portion of the rubber block 6 located inside the fixed cylinder 1 is a hemisphere.

[0066] This facilitates the compression of the rubber block 6 by the compression plate 4.

[0067] According to some embodiments of this application, optionally, the sampling device further includes a rubber pad 14, and the rubber pad 14 is provided on the outside of the extrusion plate 4.

[0068] Thus, the rubber pad 14 improves the sealing between the extrusion plate 4 and the inner wall of the fixed cylinder 1.

[0069] According to some embodiments of this application, optionally, the connection between the side of the rubber pad 14 near the rubber block 6 and the bottom of the rubber pad 14 is arc-shaped.

[0070] This facilitates the compression of the rubber block 6 by the rubber pad 14.

[0071] In practical use, when this device is needed, firstly, control bolt 10 to rotate clockwise, causing the output end of bolt 10 to move to the left, which in turn moves the annular plate 12 and L-shaped connecting rod 13 to the left, thereby moving the fixing rod 8 and rubber block 6 to the left, so that the right end of rubber block 6 is located in the through hole 9. Then, control the needle 3 to be inserted into the sampling liquid. Next, control the top plate 5 to rise, thereby moving the connecting rod 2 and squeezing plate 4 to rise, allowing the sampling liquid to enter the fixed cylinder 1 through the needle 3. After sampling, control bolt 10 to rotate counterclockwise, causing the output end of bolt 10 to move to the right, which in turn moves the annular plate 12 and L-shaped connecting rod 13 to the right, thereby moving the fixing rod 8 and rubber block 6 to the right, so that the right end of rubber block 6 is located in the through hole 9. Inside the fixed cylinder 1, the top plate 5 is pressed downwards, causing the connecting rod 2 and the squeezing plate 4 to descend and discharge excess sampling liquid from the fixed cylinder 1. When the squeezing plate 4 touches the rubber block 6, the downward squeezing of the top plate 5 can be stopped. When a quantitative amount of sampling liquid needs to be discharged from the fixed cylinder 1, the top plate 5 can be pressed downwards, causing the connecting rod 2 and the squeezing plate 4 to move downwards. At this time, the rubber pad 14 and the rubber block 6 squeeze each other. When the rubber pad 14 and the rubber block 6 are no longer squeezing each other, the resistance to the downward squeezing of the top plate 5 will decrease. When the rubber pad 14 contacts the next rubber block 6, the resistance to the downward squeezing of the top plate 5 will increase, thus allowing the sampling liquid to be discharged quantitatively. This process can be repeated as needed to discharge all the sampling liquid from the fixed cylinder 1.

[0072] Unlike existing technologies, the technical solution of this application has a connecting rod with one end located inside the fixed cylinder, a needle fixed to the bottom of the fixed cylinder and connected to the fixed cylinder, a top of the extrusion plate fixed to the bottom of the connecting rod, the extrusion plate located inside the fixed cylinder and slidably connected to the inner wall of the fixed cylinder, a bottom of the top plate fixed to the top of the connecting rod, and multiple rubber blocks fixed to the inner wall of the fixed cylinder at equal intervals. In this way, the cooperation between the rubber blocks and the pressure plate can prevent the extrusion plate from moving, thereby achieving the effect of quantitative sampling and quantitative sorting.

[0073] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
