Description

Technical Field

[0001] This utility model belongs to the field of experimental analysis technology, specifically relating to a reagent sampling device for experimental analysis. Background Technology

[0002] Experimental analysis methods utilize material means to reflect the elements, characteristics, attributes, and relationships of material objects, thereby achieving the goal of perception through the five senses. This method typically requires decomposition and disruption of the overall structure.

[0003] Reagents, also known as biochemical reagents or test reagents, are pure chemicals primarily used for chemical reactions, analytical testing, research experiments, teaching experiments, and chemical formulation. They are generally categorized by application into general-purpose reagents, high-purity reagents, analytical reagents, instrumental analysis reagents, clinical diagnostic reagents, biochemical reagents, and inorganic ion colorimetric reagents, etc.

[0004] A large amount of reagents are required in the experimental analysis process. The reagents are taken out by a sampling device. However, when the sampling device takes out the reagents in the test tube, it directly inserts into the interior of the reagents in the test tube, which can easily make it impossible to control the amount of reagents taken out by the sampling device.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] This invention features an adjustable internal threaded ring, allowing it to move to different positions on the outer wall of the sampling tube. The fitting ring is then directly fitted to the positioning groove. Installing the internal threaded ring in different positions allows the sampling tube to extend into different parts of the test tube body. Furthermore, the outer wall of the test tube body is marked with graduations, so the amount of reagent drawn into the test tube varies depending on the position of the sampling tube, thus achieving quantitative sampling.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0027] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.

[0028] Reference Figure 1-3 The present invention relates to a reagent sampling device for experimental analysis, comprising a test tube body 1, a connecting structure 2 provided at the top of the test tube body 1, and a sampling structure 3 provided inside the connecting structure 2.

[0029] The connecting structure 2 includes a support ring 201, a support frame 206 is provided on the top of the support ring 201, a positioning plate 207 is provided on the top of the support frame 206, and a positioning groove 208 is provided in the middle of the positioning plate 207.

[0030] The sampling structure 3 includes a sampling tube 301. The outer wall of the sampling tube 301 is provided with a fitting ring 302. The bottom of the fitting ring 302 is provided with an internal threaded ring 303. The internal threaded ring 303 is threadedly connected to the sampling tube 301 and fits against the inner wall of the positioning groove 208.

[0031] Furthermore, in the above technical solution, a positioning rod 202 is provided on the inner wall of the support ring 201, and a bonding block 203 is provided inside the support ring 201. Multiple bonding blocks 203 are arranged in a circular array inside the support ring 201. A positioning hole 204 is provided on one side of each bonding block 203. The positioning hole 204 is slidably connected to the positioning rod 202. A return spring 205 is provided between the positioning hole 204 and the support ring 201. The outer side of the return spring 205 is inclined. Made of rubber, when reagents are needed for experimental analysis, the support ring 201 is installed on the outer wall of the test tube body 1 and pushed downward. Then, the outer side of the adhesive block 203 is attached to the inner wall of the test tube body 1. When the support ring 201 moves downward, the support ring 201 drives the adhesive block 203 to interact downward on the inner wall of the test tube body 1. The adhesive block 203 also slides on the outer wall of the positioning rod 202 and stretches the return spring 205. The return spring 205 applies a reverse force to the adhesive block 203, thereby fixing the support ring 201 to the top of the test tube body 1.

[0032] Furthermore, in the above technical solution, a first bonding plate 304 is provided at the top of the sampling tube 301, a compression spring 308 is provided at the top of the first bonding plate 304, a connecting shaft 305 is provided inside the sampling tube 301, a sealing washer 306 is provided at the bottom of the connecting shaft 305, and a second bonding plate 307 is provided at the top of the connecting shaft 305. The second bonding plate 307 is connected to the compression spring 308. Depending on the amount of reagent to be taken out, the bonding ring 302 is rotated, and the bonding ring 302 drives the internal threaded ring 303 to move on the outer wall of the sampling tube 301 to adjust the specific insertion of the sampling tube 301 into the test tube body 1. Then the internal threaded ring 303 is... 03. When the sampling tube 301 is inserted into the test tube body 1 by fitting with the positioning groove 208, the second fitting plate 307 is released, and the compression spring 308 pushes the second fitting plate 307 upward. The second fitting plate 307 drives the connecting shaft 305 upward, and the connecting shaft 305 drives the sealing gasket 306 upward, so that the sample tube 301 is sucked into the interior, and the liquid level of the reagent inside the test tube body 1 moves downward. When the sealing gasket 306 continues to move upward, since the position of the sampling tube 301 is fixed, after the reagent leaves the bottom of the sampling tube 301, the sampling tube 301 can only suck gas into the interior and cannot continue to suck in the reagent, thereby achieving quantitative absorption of the reagent.

[0033] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
