Description

Technical Field

[0001] The invention relates to the technical field of chemical sampling equipment, in particular to a sampling equipment used for testing, detecting and analyzing chemical raw materials. Background Art

[0002] In the chemical raw material testing and analysis, the sampling tube is an important sampling device. The sampling tube is usually made of corrosion-resistant, high-temperature-resistant, and chemically stable materials, such as glass, plastic, or special alloys. Different materials are suitable for different chemical raw materials and testing requirements. They are used to collect a certain amount of samples from chemical raw materials for subsequent testing and analysis. The sampling tube can provide a relatively closed environment to prevent the sample from being contaminated by the outside world or undergoing physical and chemical changes, thereby ensuring the originality and representativeness of the sample.

[0003] However, existing sampling tubes usually use an extraction method to sample liquids. Since the extraction operation requires a lot of force and space, it may be more laborious for the operator, especially in some narrow operating environments, and it will be restricted. At the same time, it is difficult for the operator to maintain a constant speed and force when performing the extraction operation, which will cause the liquid to be inhaled or discharged at an unstable speed. If the extraction speed is too fast or uneven, the pressure in the test tube will change, causing air to enter or bubbles to be generated. These air or bubbles will occupy a certain space, making the actual sampling amount inconsistent with expectations. It may also affect the chemical properties of the sample, thereby affecting the sampling accuracy.

[0004] In addition, when the existing sampling test tubes are in use, due to the limited length of the test tube head, the sampling head usually needs to be replaced manually, and each time the sampling head is replaced, a series of operations need to be performed, such as removing the old sampling head, installing a new sampling head, etc., because manual replacement of the sampling head requires multiple steps and may require the use of tools, the operation process is relatively cumbersome, prone to operational errors or delays, thereby increasing the complexity and time cost of the operation. At the same time, in the process of replacing the sampling head, manual operation will inevitably increase the chances of contact between people and samples and sampling heads, and it is easy to come into contact with samples and sampling heads, thereby increasing the possibility of sample contamination.

[0005] Therefore, a sampling device for chemical raw material testing, detection and analysis is proposed to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a sampling device for chemical raw material testing and analysis to solve the problems that the sampling tube heads of the prior art need to be manually replaced and the existing extraction sampling is laborious and dangerous.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sampling device for chemical raw material testing, detection and analysis, comprising a sampling tube, one side of the sampling tube is fixedly connected to a fixing frame, the inner wall of the sampling tube is slidably connected to a pull rod, the middle of the pull rod is fixedly connected to a sliding plug block, the outer surface of the sliding plug block is slidably connected to the sampling tube, and the outer surface of the sampling tube is fixedly connected to an arc-shaped fixing plate. A sampling device for chemical raw material testing, detection and analysis comprises an adjustable multifunctional sampling mechanism and an adjustable telescopic mechanism, the adjustable multifunctional sampling mechanism is arranged at one end of the sampling tube close to the fixing frame, and the adjustable telescopic mechanism is arranged at one end of the sampling tube away from the fixing frame;

[0008] The adjustable multifunctional sampling mechanism is used for telescopic adjustment of sampling of chemical liquid raw materials in different environments;

[0009] The adjustable telescopic mechanism is used for adjusting and sampling the sampling tube.

[0010] Preferably, the adjustable multifunctional sampling mechanism includes a fixed rod, one end of which is fixedly connected to the outer surface of the sampling tube, and the other end of the fixed rod is provided with a sliding tube, the outer surface of the sliding tube is fixedly connected to a limiting strip, and the limiting strip is slidably connected to the fixed rod.

[0011] Preferably, the limiting strip is fixedly connected to a squeezing column on the side away from the sliding tube, the outer surface of the sliding tube is slidably connected to an adjusting cylinder, an squeezing groove is provided on the inner wall of the conveying adjusting cylinder, and the squeezing column is slidably connected in the squeezing groove.

[0012] Preferably, the outer surface of the adjusting cylinder away from the sliding tube is rotatably connected with a connecting cylinder, the inner wall of the connecting cylinder is threadedly connected to the sampling tube, and the sampling tube is connected to the connecting cylinder and the sliding tube.

[0013] Preferably, the adjustable telescopic mechanism includes a push handle, the upper end of the push handle is rotatably connected to the pull rod, an arc groove is opened in the middle of the push handle, a V-shaped adjustment plate is slidably connected in the arc groove, and the V-shaped adjustment plate is rotatably connected to the outer surface of the sampling tube at one end away from the push handle.

[0014] Preferably, a vertical groove is provided in the V-shaped adjustment plate, a square rotating block is slidably connected in the vertical groove, and a threaded shaft is threadedly connected to the middle part of the square rotating block.

[0015] Preferably, one end of the threaded shaft is rotatably connected to the sampling tube, the other end of the threaded shaft is rotatably connected to the arc-shaped fixed plate, and one end of the threaded shaft close to the sliding plug block is fixedly connected to an adjusting disk.

[0016] Preferably, a compression spring is provided in the fixing frame, one end of the compression spring is fixedly connected to the pull rod, and the other end of the compression spring is fixedly connected to the fixing frame.

[0017] Compared with the prior art, the present invention provides a sampling device for chemical raw material testing and analysis, which has the following beneficial effects:

[0018] 1. Because the composition of samples in different chemical reactions or storage containers may differ in the vertical direction, the adjustable multifunctional sampling mechanism can be used to adjust the telescopic length of the sliding tube to sample chemical samples at different depths according to the specific detection purpose, thereby ensuring that samples are obtained from different levels, making the detection results more representative, and being able to more comprehensively reflect the overall properties of chemical raw materials. Compared with the prior art, when test tubes of different lengths are required, the test tube head nozzle needs to be replaced separately. With the design of this solution, the operator can easily adjust the length of the pipette according to the specific sampling requirements and on-site conditions to adapt to various complex sampling environments.

[0019] 2. Through the setting of the adjustable telescopic mechanism, by adjusting the adjustment disk, the operator only needs to press at a fixed angle to complete the extraction of different chemical raw material liquid metering heights, so that the sampling capacity can be flexibly adjusted according to specific detection needs, which enables more accurate acquisition of the required amount of samples in different detection scenarios, avoiding detection errors or waste of resources caused by inappropriate sampling volume. Compared with the manual push-pull method in the prior art for the extraction and detection of chemical raw materials, it is easier to apply force through the pressing action than the extraction operation, and does not require a large space to complete the action like extraction, which is more ergonomic, the hand force is more natural, and the operation is easier and faster, making it more convenient to perform sampling operations in various environments. In addition, the pressing method uses the lever principle, so that the applied force is more effectively utilized, thereby reducing the physical exertion of the operator.

[0020] 3. Through the setting of the adjustable telescopic mechanism, when pressing to extract the test liquid, the pressure inside the test tube is relatively stable, because during the pressing process, the flow of the liquid is relatively smooth, and it is not easy to produce sudden pressure changes, reducing the risk of leakage caused by pressure fluctuations that may occur during the extraction process, thereby reducing the possibility of liquid leakage.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0034] Example

[0035] Please refer to Figures 1 to 7 As shown:

[0036] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a sampling device for chemical raw material testing, detection and analysis, including a sampling tube 1, a fixed frame 101 is fixedly connected to one side of the sampling tube 1, a pull rod 102 is slidably connected to the inner wall of the sampling tube 1, a sliding plug block 103 is fixedly connected to the middle of the pull rod 102, the outer surface of the sliding plug block 103 is slidably connected to the sampling tube 1, and an arc-shaped fixed plate 104 is fixedly connected to the outer surface of the sampling tube 1. A sampling device for chemical raw material testing, detection and analysis includes an adjustable multifunctional sampling mechanism 2 and an adjustable telescopic mechanism 3, the adjustable multifunctional sampling mechanism 2 is arranged at one end of the sampling tube 1 close to the fixed frame 101, and the adjustable telescopic mechanism 3 is arranged at one end of the sampling tube 1 away from the fixed frame 101;

[0037] The adjustable multifunctional sampling mechanism 2 is used for telescopic adjustment of sampling of chemical liquid raw materials in different environments;

[0038] The adjustable multifunctional sampling mechanism 2 comprises a fixed rod 201, one end of which is fixedly connected to the outer surface of the sampling tube 1, and the other end of the fixed rod 201 is provided with a sliding tube 202, the outer surface of the sliding tube 202 is fixedly connected to a limiting strip 203, and the limiting strip 203 is slidably connected to the fixed rod 201;

[0039] The limiting strip 203 is fixedly connected to a side away from the slide tube 202 with an extrusion column 204, the outer surface of the slide tube 202 is slidably connected to an adjustment cylinder 205, the inner wall of the delivery adjustment cylinder 205 is provided with an extrusion groove 206, and the extrusion column 204 is slidably connected in the extrusion groove 206;

[0040] The outer surface of the adjusting cylinder 205 away from the sliding tube 202 is rotatably connected with a connecting cylinder 207, and the inner wall of the connecting cylinder 207 is threadedly connected to the sampling tube 1;

[0041] Wherein: the sampling tube 1 is connected with the connecting tube 207 and the sliding tube 202 .

[0042] In the prior art, the sampling tube usually adopts the extraction method to sample the liquid. Since the extraction operation requires a large amount of force and space, it may be laborious for the operator, especially in some narrow operating environments, which may be restricted. At the same time, it is difficult for the operator to maintain a constant speed and force when performing the extraction operation, which will cause the liquid to be inhaled or discharged at an unstable speed. If the extraction speed is too fast or uneven, the pressure in the test tube will change, thereby causing air to enter or bubbles to be generated. These air or bubbles will occupy a certain space, making the actual sampling volume inconsistent with expectations, and may also affect the chemical properties of the sample. The properties of the chemical raw materials are affected, thereby affecting the accuracy of sampling. Compared with the prior art, through the implementation of this embodiment, by adjusting the telescopic length of the sliding tube 202, sampling can be carried out in chemical samples of different depths according to the specific detection purpose, thereby ensuring that samples are obtained from different levels, making the detection results more representative, and being able to more comprehensively reflect the overall properties of the chemical raw materials. Compared with the prior art, when test tubes of different lengths are required, it is necessary to replace the test tube head nozzle separately. With the design of this solution, the operator can easily adjust the straw length according to the specific sampling requirements and on-site conditions to adapt to various complex sampling environments.

[0043] For further examples, please refer to Figures 1 to 7 As shown:

[0044] The adjustable telescopic mechanism 3 is used for adjusting and sampling the sampling tube 1;

[0045] The adjustable telescopic mechanism 3 includes a pressing handle 301, the upper end of the pressing handle 301 is rotatably connected to the pull rod 102, an arc groove 302 is provided in the middle of the pressing handle 301, a V-shaped adjustment plate 303 is slidably connected in the arc groove 302, and the V-shaped adjustment plate 303 is rotatably connected to the outer surface of the sampling tube 1 at one end away from the pressing handle 301;

[0046] A vertical groove 307 is formed in the V-shaped adjustment plate 303, a square rotating block 304 is slidably connected in the vertical groove 307, and a threaded shaft 305 is threadedly connected in the middle of the square rotating block 304;

[0047] One end of the threaded shaft 305 is rotatably connected to the sampling tube 1, and the other end of the threaded shaft 305 is rotatably connected to the arc-shaped fixed plate 104. One end of the threaded shaft 305 close to the sliding plug block 103 is fixedly connected to an adjusting disk 306;

[0048] A pressing spring 308 is provided in the fixing frame 101, one end of the pressing spring 308 is fixedly connected to the pull rod 102, and the other end of the pressing spring 308 is fixedly connected to the fixing frame 101;

[0049] Among them: the operator slowly loosens and presses the handle 301, and at this time, due to the elastic action of the pressing spring 308, the pull rod 102 will start to be pushed to the right. At this time, the liquid in the sampling tube 1 will be transported along the connecting tube 207, the adjusting tube 205 and the sliding tube 202 to flow into the detection vessel because the pull rod 102 pushes the sliding plug block 103.

[0050] In the prior art, when a sampling test tube is in use, due to the limited length of the test tube head, it is usually necessary to manually replace the sampling head, and each time the sampling head is replaced, a series of operations need to be performed, such as removing the old sampling head, installing a new sampling head, etc., because manual replacement of the sampling head requires multiple steps and may require the use of tools, the operation process is relatively cumbersome, prone to operating errors or delays, thereby increasing the complexity and time cost of the operation. Compared with the prior art, through the implementation of this embodiment, by adjusting the adjustment disk 306, the operator only needs to perform a fixed pressing angle to complete the extraction of different chemical raw material liquid metering heights, so that the sampling capacity can be flexibly adjusted according to specific detection requirements. This enables more accurate acquisition of the required amount of sample in different detection scenarios, avoiding detection errors or waste of resources due to inappropriate sampling volume.

[0051] Everything in the above example works like this:

[0052] In the initial state: the pressing spring 308 is not compressed.

[0053] The following is the working process of the adjustable multifunctional sampling mechanism 2 for the telescopic adjustment of sampling of chemical liquid raw materials in different environments:

[0054] First, before sampling and testing chemical liquid raw materials, the telescopic length of the slide tube 202 can be adjusted according to the sampling environment, which is conducive to sampling operations in narrow places. First, the operator manually rotates the extrusion groove 206 in a counterclockwise direction. At this time, because the extrusion groove 206 is rotatably connected to the inner wall of the connecting cylinder 207, and the sampling tube 1, the connecting cylinder 207 and the adjusting cylinder 205 are interconnected, and because the inner wall of the adjusting cylinder 205 is provided with an extrusion groove 206, and the slide tube 202 is slidably connected to the inner wall of the adjusting cylinder 205, at the same time When the adjusting cylinder 205 is rotated in the counterclockwise direction, the squeezing column 204 fixedly connected to the adjusting cylinder 205 slides in the squeezing groove 206. As the adjusting cylinder 205 rotates in the counterclockwise direction, the squeezing groove 206 starts to gradually squeeze the squeezing column 204. Because the limit bar 203 fixedly connected to the bottom of the slide tube 202 is slidably connected to the fixed rod 201 for limiting, the slide tube 202 is prevented from rotating in the squeezing groove 206. Due to the squeezing of the squeezing groove 206, the squeezing column 204 drives the slide tube 202 to start sliding to the right along the inner wall of the adjusting cylinder 205. When the operator When the operator rotates the adjusting cylinder 205 to make the slide tube 202 slide to the right for a suitable length and to facilitate the sampling of the reagent in the environment, the operator can stop rotating the adjusting cylinder 205. Similarly, when the slide tube 202 needs to be retracted, the operator only needs to rotate the adjusting cylinder 205 clockwise to drive the slide tube 202 to start sliding to the left on the inner wall of the adjusting cylinder 205. When the left side of the slide tube 202 slides to the left along the inner wall of the adjusting cylinder 205 and contacts the connecting cylinder 207, the slide tube 202 is blocked by the connecting cylinder 207. 202 no longer continues to slide to the left, and the sliding tube 202 is completely retracted in the inner wall of the adjusting cylinder 205. The operator manually rotates the adjusting cylinder 205. Because the diameter of the adjusting cylinder 205 is relatively long, the needle head can be extended by rotating the adjusting cylinder 205 to better adapt to drug containers of different specifications and shapes, ensuring that the drug can be effectively extracted and reducing the problem of difficult or insufficient extraction caused by the shape of the container, thereby completing the adjustment of the sliding tube 202 before the chemical liquid is away from sampling and testing.

[0055] Because the composition of samples in different chemical reactions or storage containers may differ in the vertical direction, the adjustable multifunctional sampling mechanism 2 can be set to adjust the telescopic length of the slide tube 202 to sample chemical samples at different depths according to the specific detection purpose, thereby ensuring that samples are obtained from different levels, making the detection results more representative, and being able to more comprehensively reflect the overall properties of chemical raw materials. Compared with the prior art, when test tubes of different lengths are required, the test tube head nozzle needs to be replaced separately. With the design of this solution, the operator can easily adjust the length of the pipette according to the specific sampling requirements and on-site conditions to adapt to various complex sampling environments;

[0056] At the same time, because chemical testing has high requirements for accuracy, slight errors may lead to erroneous conclusions. The adjustable multifunctional sampling mechanism 2 can not only accurately control the sampling position, but also the operator can manually rotate the adjusting cylinder 205. Because the diameter of the adjusting cylinder 205 is relatively long, the needle head that can be extended by rotating the adjusting cylinder 205 can better adapt to drug containers of different specifications and shapes, ensuring that the drug can be effectively extracted, reducing the problem of difficult or insufficient extraction caused by container shape restrictions, and reducing interference with samples at other levels during the sampling process, thereby reducing the risk of sample contamination and ensuring the purity and originality of the sample.

[0057] Please refer to the above working process Figures 1 to 7 .

[0058] The following is the working process of the adjustable telescopic mechanism 3 for adjusting the sampling of the sampling tube 1:

[0059] First, the length of the slide tube 202 is adjusted by the adjustable multifunctional sampling mechanism 2, so that the slide tube 202 is adjusted to a suitable sampling length. At this time, the operator can adjust the adjustment disk 306 according to the sampling measurement of the on-site environment, such as Figure 6 As shown, at this time, the operator manually rotates the adjusting disk 306 clockwise, because the middle part of the adjusting disk 306 is fixedly connected to the threaded shaft 305, and at the same time, one end of the threaded shaft 305 is rotatably connected to the arc-shaped fixed plate 104, and the other end is rotatably connected to the sampling tube 1, so the clockwise rotation of the adjusting disk 306 will drive the threaded shaft 305 to rotate synchronously. At this time, because the outer surface of the threaded shaft 305 is threadedly connected to the middle part of the square rotating block 304, and the two ends of the square rotating block 304 slide in the vertical grooves 307 provided on the V-shaped adjusting plate 303, the clockwise rotation of the threaded shaft 305 will drive the square rotating The rotating block 304 starts to move to the right. At this time, because one end of the V-shaped adjusting plate 303 is rotatably connected to the bottom of the sampling tube 1, and the other end of the V-shaped adjusting plate 303 is slidably connected to the arc groove 302 opened by the pressing handle 301, the square rotating block 304 moves to the right, which drives the V-shaped adjusting plate 303 to start rotating counterclockwise at the bottom of the sampling tube 1. At the same time, because the square rotating block 304 slides in the arc groove 302, the V-shaped adjusting plate 303 starts to slide downward along the arc groove 302. When the V-shaped adjusting plate 303 slides to the lower end of the arc groove 302, the operator stops rotating the adjusting disk 306.

[0060] Furthermore, the operator can perform sampling inspection on the maximum scale value of the sampling tube 1. At the same time, the operator only needs to hold the outer surface of the pressing handle 301 and the outer surface of the arc-shaped fixing plate 104 with his hands. When the operator presses hard, the upper end of the pressing handle 301 is rotatably connected to the pull rod 102, and the pull rod 102 is fixedly connected to the sliding block 103 away from the pressing handle 301. Because the sliding block 103 slides in the sampling tube 1 and has good airtightness, the sliding block 103 is OK, so by pressing the pressing handle 301, the pressing handle 301 will start to rotate counterclockwise around the fulcrum V-shaped adjustment plate 303. At this time, the pressing handle 301 starts to drive the pull rod 102 to slide to the left. Because one end of the pressing spring 308 is fixedly connected to the pull rod 102 and the other end is fixedly connected to the fixing frame 101, when the pull rod 102 slides to the left, the pressing spring 308 starts to press to the left. When the slide block 103 slides to the left, the slide block 103 will start to slide to the left on the inner wall of the sampling tube 1. Since the sampling tube 1 is connected with the connecting tube 207, the adjusting tube 205 and the slide tube 202, when the slide tube 202 is inserted into the sampling liquid layer, the slide block 103 slides to the left, causing a certain air pressure suction force to be generated on the inner wall of the sampling tube 1. Therefore, the liquid to be sampled will be sucked into the sampling tube 1 through the suction force. At this time, the operator will automatically transfer the sampled liquid from the sampling tube 1 to the detection vessel again. At this time, the slide tube 202 is aligned with the detection vessel, and the operator slowly loosens and presses the grip 301. At this time, due to the elastic action of the pressing spring 308, the pull rod 102 will start to be pushed to the right. At this time, the liquid in the sampling tube 1 will be transported along the connecting tube 207, the adjusting tube 205 and the slide tube 202 to the detection vessel because the pull rod 102 pushes the slide block 103 to complete the liquid sampling detection of the chemical raw materials.

[0061] Under the setting of the adjustable telescopic mechanism 3, by adjusting the adjustment disk 306, the operator only needs to press at a fixed angle to complete the extraction of different chemical raw material liquid metering heights, so that the sampling capacity can be flexibly adjusted according to specific detection requirements, which enables more accurate acquisition of the required amount of samples in different detection scenarios, avoiding detection errors or waste of resources caused by inappropriate sampling volume. Compared with the manual push-pull method in the prior art for extracting and testing chemical raw materials, it is easier to apply force through the pressing action than the extraction operation, and does not require a large space to complete the action like extraction, which is more ergonomic, more natural to use hand force, easier and faster to operate, so that sampling operations can be more conveniently performed in various environments, and the pressing method uses the lever principle, so that the applied force is more effectively utilized, thereby reducing the physical exertion of the operator;

[0062] When the test liquid is extracted by pressing, the pressure inside the test tube is relatively stable because the flow of the liquid during the pressing process is relatively smooth and sudden pressure changes are not easy to occur, reducing the risk of leakage caused by pressure fluctuations that may occur during the extraction process, thereby reducing the possibility of liquid leakage.
