Description

Technical Field

[0001] This utility model relates to the field of gas detection equipment technology, specifically a markable gas detection sampling tube. Background Technology

[0002] In the field of gas detection, sampling tubes are the core tool for collecting gas samples and are widely used in environmental monitoring, industrial production, chemical testing and other scenarios.

[0003] Existing sampling tubes generally lack integrated marking structures and rely more on external labels or handwritten markings, which are prone to wear and tear and falling off. When sampling in multiple batches and at multiple locations, the risk of sample confusion is high, making it difficult to effectively trace the source of test results.

[0004] A search revealed existing technology (application number: CN202420862186.0), which describes "a gas sampling tube". This utility model includes a sampling tube and a collection tank. A disassembly / assembly mechanism is provided at the air inlet of the sampling tube, and a collection mechanism is provided between the sampling tube and the collection tank. The disassembly / assembly mechanism includes a fixed sleeve and a connecting sleeve. A filter screen is fixedly installed on the inner wall of the connecting sleeve, and a movable cavity is opened inside the fixed sleeve. A squeezing block is slidably connected to the inner wall of the movable cavity.

[0005] However, while existing technologies have effectively improved the efficiency of gas sampling and reduced the cost of gas sampling, they still have some shortcomings: gas samples are mostly colorless and transparent, making it difficult to distinguish between multiple samples when sampling multiple samples, which may cause them to be confused. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a labelable gas detection sampling tube.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a markable gas detection sampling tube, wherein a stopper is provided through the top of the sampling tube, and a sealing strip is provided at the connection between the stopper and the sampling tube; the stopper is hollow inside and has a fan-shaped groove on the top, and a marking component is provided inside the stopper; a sampling gas tube has an air inlet on one side and a sampling component is provided inside.

[0008] As a further description of the above technical solution:

[0009] The marking assembly includes: a label disk, which is rotatably disposed inside the stopper; and a rotating shaft, which is rotatably connected to the top of the stopper and fixedly connected to the label disk.

[0010] As a further description of the above technical solution:

[0011] The marking assembly further includes an elastic sheet, which is fixedly disposed on the inner wall of the stopper and abuts against the outer side of the marking disk.

[0012] As a further description of the above technical solution:

[0013] The sampling assembly includes: a piston, which is slidably disposed inside the sampling tube and fixedly connected to a handle on one side; and an outlet, which is fixedly disposed on one side of the sampling tube.

[0014] As a further description of the above technical solution:

[0015] The sampling assembly further includes a handle, which is rotatably disposed in the middle of the sampling tube and fixedly connected to a ball valve at its bottom, and the ball valve is rotatably disposed on the inner wall of the sampling tube.

[0016] As a further description of the above technical solution:

[0017] The ball valve is spherical and has a three-way groove inside, with the groove corresponding to the air outlet.

[0018] As a further description of the above technical solution:

[0019] The top of the labeling disk is fixed with numerical labels.

[0020] This utility model has the following beneficial effects:

[0021] 1. Through the digital labeling, rotatable adjustment and elastic sheet positioning structure of the marking component, the sample can be quickly and accurately marked and the marking position can be stably fixed, which can effectively avoid sample confusion when sampling from multiple batches and multiple locations, and ensure the accuracy of detection and traceability.

[0022] 2.

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.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment provides a labelable gas detection sampling tube, including: a sampling tube 1, with a plug 2 extending through the top, and a sealing strip provided at the connection between the plug 2 and the sampling tube 1; the plug 2 is hollow inside and has a fan-shaped groove 3 on the top, and a marking component is provided inside the plug 2; and a sampling gas tube 4, with an air inlet 5 on one side and a sampling component inside.

[0033] In this embodiment, the marking component and the collecting component constitute a markable gas detection sampling tube according to this application.

[0034] Understandable Figure 1 This illustration only schematically shows some components of a labelable gas detection sampling tube; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, a labelable gas detection sampling tube can also include, compared to... Figure 1 More or fewer parts.

[0035] In addition, in this embodiment, the plug 2 forms a seal with the sampling tube 1 through the sealing strip to prevent gas leakage inside the sampling tube 1 or the ingress of external gas, thereby ensuring the sealing performance of the sampling tube 1 and maintaining the purity of the sample.

[0036] Specifically, the marking assembly includes: a label disk 32, which is rotatably disposed inside the stopper 2; and a rotating shaft 31, which is rotatably connected to the top of the stopper 2 and fixedly connected to the label disk 32.

[0037] In this embodiment, rotating the shaft 31 drives the label disk 32 to rotate synchronously to achieve label position adjustment. The cooperation between the shaft 31 and the label disk 32 provides a basis for sample labeling.

[0038] Specifically, the marking assembly further includes an elastic sheet 33, which is fixedly disposed on the inner wall of the stopper 2 and abuts against the outer side of the label disk 32.

[0039] As a preferred implementation, the elastic sheet 33 exerts a clamping force on the label disk 32 through its own elasticity, restricting the label disk 32 from rotating freely, ensuring that the position of the label disk 32 is fixed after adjustment, and avoiding label offset.

[0040] Example 2:

[0041] Based on Example 1, in order to further improve the collection efficiency, an air extraction device is arranged in the sampling component;

[0042] Specifically, the sampling assembly includes: a piston 8, which is slidably disposed inside the sampling air tube 4 and fixedly connected to the handle 7 on one side; and an air outlet 6, which is fixedly disposed on one side of the sampling air tube 4.

[0043] In this embodiment, pushing or pulling the handle 7 causes the piston 8 to slide inside the sampling tube 4, changing the internal volume of the sampling tube 4, thereby realizing the intake or exhaust of gas and achieving sampling and discharge control.

[0044] Specifically, the sampling assembly further includes: a handle 9, which is rotatably disposed in the middle of the sampling air tube 4 and fixedly connected to the ball valve 42 at its bottom, and the ball valve 42 is rotatably disposed on the inner wall of the sampling air tube 4.

[0045] With this configuration, rotating the handle 9 causes the ball valve 42 to rotate synchronously, adjusting the connection between the ball valve 42 and the outlet 6 of the sampling gas pipe 4, thereby achieving the switching and on / off control of the gas flow path.

[0046] Example 3:

[0047] Based on Example 2, a guide mechanism is arranged inside the ball valve 42 in order to change the gas flow direction and assist in labeling the sample;

[0048] Specifically, the ball valve 42 is spherical and has a three-way groove inside, and the groove corresponds to the air outlet 6.

[0049] When the ball valve 42 rotates, the three-way groove can form different communication combinations with the gas outlet 6 inside the sampling gas pipe 4, changing the gas flow direction and realizing multi-path gas flow control.

[0050] Specifically, a number is fixedly installed on the top of the label disk 32.

[0051] In this embodiment, the label disk 32 is rotated so that the target number label is aligned with the fan-shaped groove 3 on the top of the plug 2 to mark the sample. The different samples are intuitively distinguished by the number label to avoid sample confusion.

[0052] In actual use, pulling the handle 7 drives the piston 8 to move inside the sampling tube 4, so that gas is drawn into the sampling tube 4 from the inlet 5. Then, rotating the handle 9 aligns the through groove of the ball valve 42 with the outlet 6, and at the same time, aligns the top of the sampling tube 1 with the outlet 6. Squeezing the handle 7 causes the piston 8 to push the gas into the outlet 6. Then, the plug 2 is closed to collect the gas. At the same time, rotating the shaft 31 makes the marking on the label disk 32 appear in the fan-shaped groove 3, thus marking the marking. Meanwhile, the elastic plate 33 squeezes and restricts the label disk 32, making the label disk 32 stable.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
