Description

Technical Field

[0001] This utility model relates to the field of microbial sampler technology, and in particular to an auxiliary rod and sampling device for a sampling apparatus. Background Technology

[0002] Microorganisms are tiny organisms invisible or barely visible to the naked eye. They are small in size and have simple structures, typically requiring an optical or electron microscope to be clearly seen. However, most products on the market have extremely strict requirements regarding the number of microorganisms present. Therefore, it is necessary to test whether the number of microorganisms in a product meets these specifications.

[0003] However, this test requires the use of a sampling device, and the auxiliary rod in the sampling device plays an important role in the sampling process. The auxiliary rod can help fix the sampling device, prevent the device from shaking or shifting during the sampling process, and ensure the accuracy of the sampling.

[0004] Existing patent (CN214218720U) discloses a microbial sampler. This device uses a handle assembly to cause cylinder I to slide down, while simultaneously squeezing a spring. The sampling cap slides out of the sampling port along with cylinder II, creating a negative pressure inside the tube, which allows microorganisms to be drawn into the sampling tube through the sampling port. The spring returns to its original position, allowing the sampling cap to form a sealed fit with the sampling port. However, this device can only sample from one angle. For other angle changes, manual adjustment is required. When manually changing the angle, it is difficult to ensure that the angle is accurate and consistent each time, resulting in inaccurate experimental data. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This embodiment provides an auxiliary rod for a sampling device, such as... Figure 1 As shown, the device includes a rod 1 and an adjustment mechanism 4. The adjustment mechanism 4 includes a fixed part and a rotating part. The fixed part is fixedly connected to the rod 1, and the rotating part is fixedly connected to the sampling mechanism. The rotating part and the fixed part form a rotatable connection around a rotation axis, which is perpendicular to the extension direction of the rod 1. The rotation of the rotating part relative to the fixed part around the rotation axis can drive the sampling mechanism to rotate relative to the rod 1. This embodiment, by setting up a rod 1 and an adjustment mechanism 4, the adjustment mechanism 4 includes a fixed part and a rotating part. The fixed part is fixedly connected to the rod 1, one end of the adjustment mechanism 4 is fixedly connected to the rotating part, and the other end is fixedly connected to the sampling mechanism. The rotating part and the fixed part form a rotatable connection around a rotation axis, which is perpendicular to the extension direction of the rod 1. The rotation of the rotating part relative to the fixed part around the rotation axis can drive the sampling mechanism to rotate relative to the rod 1, so that the sampling mechanism can meet the sampling requirements at different positions, making the sampling device not only easy to use but also improving the accuracy of experimental data.

[0031] In some embodiments of this example, the adjusting mechanism 4 further includes a locking part, which is used to lock the relative position of the rotating part and the fixed part. The locking part can ensure that the rotating part remains fixed during the sampling process, avoid the positional deviation of the sampling mechanism due to accidental rotation, and ensure that each sampling is performed at a specific position, thereby improving the consistency and reliability of the sampled samples.

[0032] In some embodiments of this example, the fixing part includes two connecting members 41 arranged sequentially along a direction parallel to the rotation axis. Both connecting members 41 are fixedly connected to the rod body 1. The rotating part includes a turntable 46, which is disposed between the two connecting members 41. The turntable 46 is used to be fixedly connected to the sampling mechanism, and the turntable 46 and the two connecting members 41 are rotatably connected around the rotation axis. The fixed connection between the connecting members 41 and the rod body 1 provides stable support for the rotating turntable 46 and the sampling mechanism connected thereto, reducing the influence and interference of external factors on the sampling mechanism. At the same time, the rotatable connection between the turntable 46 and the connecting members 41 can buffer external vibrations and impacts to a certain extent, preventing external forces from being directly transmitted to the sampling mechanism, thereby protecting the accuracy and performance of the sampling mechanism and extending its service life.

[0033] In some embodiments of this example, the two connectors 41 are a first connector and a second connector, respectively. The locking part includes a first screw 43 and a first knob 44. The first nut of the first screw 43 is located on one side of the first connector and is used to restrict the axial movement of the first screw 43 relative to the first connector. The end of the first screw 43 away from the first nut passes through the first connector, the turntable 46 and the second connector in sequence. The first knob 44 is threaded onto the body of the first screw 43 and is at least partially located on the side of the second connector away from the first nut. The turntable 46 has a first groove 47 on one end face near the first knob 44. When the first knob 44 is tightened, the first knob 44 can pass through the second connector and be inserted into the first groove 47 to press the turntable 46 onto the first connector to fix the relative position of the turntable 46 and the connector 41. The first nut and the first knob 44 are located on opposite sides of the two connecting parts 41. When the first knob 44 is tightened, the first nut and the first knob 44 exert a bidirectional squeezing force on the turntable 46, which can more firmly fix the turntable 46 between the two connecting parts 41. This effectively prevents the turntable 46 from undergoing slight displacement or rotation due to external forces in various directions during sampling, ensuring the accuracy and stability of the sampling position and improving sampling precision. By tightening or loosening the first knob 44, the turntable 46 can be quickly fixed or rotated. When sampling is required, loosening the first knob 44 allows the turntable 46 to rotate flexibly, facilitating the adjustment of the sampling mechanism's position. After the sampling position is determined, tightening the first knob 44 quickly locks the turntable 46 in the appropriate position, improving sampling efficiency.

[0034] In some implementations of this embodiment, such as Figure 4-6 As shown, the first knob 44 includes a handle and a push rod 45. The push rod 45 is fixedly mounted on one end of the handle. The handle is threaded onto the body of the first screw 43. The push rod 45 is sleeved on the body of the first screw 43 and can pass through the second connector. When the handle is tightened, the push rod 45 can be inserted into the first groove 47 and press the turntable 46 against the first connector. The handle increases the contact area between the operator's hand and the first knob, making it easier for the operator to grip and apply force. By rotating the handle, the push rod 45 can be moved quickly, thereby locking and unlocking the turntable 46 and improving experimental efficiency.

[0035] Example 2

[0036] In some implementations of this embodiment, such as Figure 2 As shown, the sampling mechanism includes a first sampling plate 49, a second sampling plate 411, and a second screw 410. The first sampling plate 49 is fixedly connected to the rotating part. A second knob 412 is provided on the side near the second sampling plate 411. The second nut of the second screw 410 is located on one side of the first sampling plate 49 and is used to limit the axial movement of the second screw 410 relative to the first sampling plate 49. The end of the rod of the second screw 410 away from the second nut passes through the second sampling plate 411 and the first sampling plate 49 in sequence. The second knob 412 is threadedly connected to the rod of the second screw 410 and is at least partially located on the side of the second sampling plate 411 away from the second nut. Tightening the second knob 412 can press the second sampling plate 411 onto the first sampling plate 49 to fix the relative position of the first sampling plate 49 and the second sampling plate 411. By tightening the second knob 412, the second nut and the second knob 412 clamp the first sampling plate 49 and the second sampling plate 411, which can firmly fix the collected microbial sample between the two sampling plates, preventing the sample from moving, falling or being disturbed by the outside world during the transfer, transportation or subsequent processing after sampling, ensuring the integrity of the sample, and facilitating accurate analysis and research of microbial samples.

[0037] Example 3

[0038] In some implementations of this embodiment, such as Figure 3 As shown, the sampling mechanism includes a sampling plate 415, which is fixedly connected to a rotating part via a fixing member 413. A second groove 42 is provided on the sampling plate 415 to limit the sampling area. The sampling plate 415 is fixedly connected to the rotating part, allowing precise control of its position and angle. This ensures that the second groove 42 accurately reaches the desired sampling location and effectively limits the area to which the sampling is to be performed. The design of the second groove 42 facilitates sampling, enables precise sampling, and improves sampling accuracy.

[0039] In some embodiments of this example, the sampling mechanism further includes a connecting rod 414, one end of which is fixedly connected to the sampling plate 415, and the other end is fixedly connected to the fixing member 413. The connecting rod 414 ensures that the sampling plate will not move or shake arbitrarily during the sampling process, thereby ensuring that each sampling is performed in an accurate position, improving the accuracy and reliability of the sampling.

[0040] In some embodiments of this example, a connector 5 is fixedly mounted on the rod 1, and the connector 5 is detachably connected to the adjustment mechanism 4. This detachable connection between the rod 1 and the adjustment mechanism 4 allows the sampling device to assemble the appropriate rod 1 and adjustment mechanism 4 according to different usage requirements, thus meeting the needs of various sampling scenarios.

[0041] This embodiment provides a sampling device, including a sampling mechanism and an auxiliary rod of the sampling device in Embodiment 1, Embodiment 2, or Embodiment 3. This embodiment uses a rod body 1 and an adjustment mechanism 4. The adjustment mechanism 4 includes a fixed part and a rotating part. The fixed part is fixedly connected to the rod body 1. One end of the adjustment mechanism is fixedly connected to the rotating part, and the other end is fixedly connected to the sampling mechanism. The rotating part and the fixed part are rotatably connected around a rotation axis perpendicular to the extension direction of the rod body 1. The rotation of the rotating part relative to the fixed part around the rotation axis can drive the sampling mechanism to rotate relative to the rod body 1, enabling the sampling mechanism to meet sampling requirements at different positions. This makes the sampling device not only easy to use but also improves the accuracy of experimental data.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
