Description

Technical Field

[0001] This utility model relates to the field of concentration test strip technology, specifically to an auxiliary device for the production and testing of concentration test strips. Background Technology

[0002] Concentration test strips are portable tools that rapidly detect the concentration of target substances in liquids, gases, or solids through chemical reactions or physical adsorption. They are usually presented in the form of test strips or test cards. Their core principle is to use specific reagents to react with the analyte to produce a color change, and then read the quantitative result by colorimetry or instruments.

[0003] pH concentration test strips indirectly reflect hydrogen ion concentration (i.e., acidity / alkalinity) through color changes and are a type of concentration detection tool. pH concentration test strips are tested during production, but existing testing devices cannot verify the results. Therefore, an auxiliary device for pH concentration test strip production and testing is proposed. The bottom of the pH concentration test strip is inserted into a transparent tube to detect the pH value of the liquid inside. A pH testing pen detects and displays the pH value of the liquid inside the transparent tube. By observing the pH testing pen's result and comparing it with the result detected by the pH concentration test strip, the detection capability of the pH concentration test strip can be tested.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] The bottom of the pH concentration test strip is inserted into a transparent tube to measure the pH value of the liquid inside. A pH testing pen measures and displays the pH value of the liquid inside the tube. By observing the result of the pH testing pen and comparing it with the result of the pH concentration test strip, the detection capability of the pH concentration test strip can be tested. Figure 1-4 As shown, the present invention provides an auxiliary device for the production and testing of concentration test strips, including a pH test pen 1. A circular metal plate 2 is sleeved on the outer side of the top detection end of the pH test pen 1, and a transparent cylinder 3 is sleeved on the top of the circular metal plate 2 located on the outer side of the detection end of the pH test pen 1. The circular metal plate 2 is provided with a telescopic component 4 on the top of one side of the transparent cylinder 3. The telescopic component 4 is provided with a clamping component 5 at its top. The clamping component 5 includes a top plate 501. A reserved groove 502 is provided through the top plate 501. An n-shaped plate sleeve 503 is provided on one side of the reserved groove 502. A second spring 504 is fixed between the n-shaped plate sleeve 503 and the reserved groove 502 by bolts.

[0017] In use, the second spring 504 pushes the n-shaped plate sleeve 503 to move, which can hold the top of the pH concentration test strip inserted into the reserved groove 502. The transparent tube 3 is used to hold the chemical liquid, and the pH test pen 1 can detect the acidity or alkalinity of the chemical liquid in the transparent tube 3.

[0018] For example, such as Figure 2 As shown, the present invention also includes the telescopic component 4, which includes a sleeve 401 fixed to the top of the circular metal plate 2 by bolts, a telescopic rod 402 sleeved at the top of the sleeve 401, and the top plate 501 fixed to the top of the telescopic rod 402 by bolts.

[0019] In use, the telescopic rod 402 is sleeved on the top of the sleeve 401 and can extend and retract, making it easy to adjust the height of the clamping component 5 and the pH concentration test strip it holds.

[0020] For example, such as Figure 2 As shown, the present invention also includes a first spring 403 fixed inside the sleeve 401 by bolts, a limit block 404 connected to the bottom end of the telescopic rod 402 inside the sleeve 401 by a threaded groove, and the top end of the first spring 403 fixed to the bottom of the limit block 404 by bolts.

[0021] During use, the limiting block 404 can prevent the telescopic rod 402 from falling out of the sleeve 401, and the first spring 403 is used to move the telescopic rod 402 upward and reset it.

[0022] For example, such as Figure 2 As shown, the present invention also includes a limiting groove 405 formed on both sides of the sleeve 401, and a limiting protrusion 406 provided on both sides of the limiting block 404, wherein the limiting protrusion 406 is located inside the limiting groove 405.

[0023] During use, the limiting groove 405 and the limiting protrusion 406 can prevent the telescopic rod 402 from rotating without affecting its up and down movement.

[0024] For example, such as Figure 1 As shown, this utility model also includes a pH value comparison table 6 glued to one side of the sleeve 401.

[0025] When using it, compare the pH concentration test strip with pH value reference table 6. The acidity or alkalinity of the chemical liquid can be visually displayed by color or numerical range.

[0026] For example, such as Figure 4 As shown, the present invention also includes a sealing sleeve 7 provided between the transparent tube 3 and the detection end of the pH test pen 1.

[0027] During use, the sealing sleeve 7 seals the transparent tube 3 and the detection end of the pH test pen 1 to prevent the chemical liquid poured into the transparent tube 3 from leaking.

[0028] When using this utility model, the operator pours the chemical liquid into the transparent cylinder 3, pulls the n-shaped plate sleeve 503 to insert the pH concentration test strip into the reserved groove 502, and after releasing the n-shaped plate sleeve 503, the second spring 504 pushes the n-shaped plate sleeve 503 to move and clamp the pH concentration test strip inserted into the reserved groove 502. The downward telescopic rod 402 moves the clamped pH concentration test strip downward, and the bottom end of the pH concentration test strip is inserted into the transparent tube 3. The pH concentration test strip detects the pH value of the chemical liquid in the transparent tube 3. After the bottom end of the pH concentration test strip is inserted into the transparent tube 3 and comes into contact with the chemical liquid, it will change color according to the acidity or alkalinity of the chemical liquid. By observing the color on the pH concentration test strip with reference to the pH value reference table 6, the acidity or alkalinity of the chemical liquid can be determined. After the telescopic rod 402 is released, the first spring 403 pushes the telescopic rod 402 upward through the limiting block 404, thereby causing the pH concentration test strip after testing to move upward and reset. The limiting groove 405 and the limiting protrusion 406 can prevent the telescopic rod 402 from rotating without affecting its up and down movement. The pH test pen 1 is used to test the acidity or alkalinity of the chemical liquid in the transparent tube 3. By comparing the result with that obtained from the pH concentration test strip, it can be determined whether the result obtained from the pH concentration test strip is accurate, thus achieving the purpose of testing the pH concentration test strip.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
