Description

Technical Field

[0001] This utility model relates to the field of biological experimental instrument technology, and in particular to a comparative observation box for the antioxidant experiment of corn silk polysaccharide. Background Technology

[0002] Corn silk polysaccharide is a natural active ingredient extracted from corn silk. Due to its antioxidant and anti-inflammatory biological activities, it has become a hot topic in natural product research. Antioxidant experiments are a common method to detect the ability of substances to scavenge free radicals. Antioxidant activity is judged by the color change of the reaction solution and instrument detection. The comparison observation box is a special device to assist this experiment, which is used to realize the simultaneous reaction of multiple samples and the comparison of results, thereby realizing the antioxidant experiment.

[0003] When comparing the antioxidant capacity of different samples in an antioxidant experiment using corn silk polysaccharide, a comparative observation kit for the antioxidant experiment of corn silk polysaccharide is often required. In the existing technology, researchers usually place test tubes containing the corn silk polysaccharide solution to be tested, blank control solution, and positive control solution directly on a regular laboratory bench and a simple stand. After adding the colorimetric reagent, the laboratory environment naturally controls the temperature, and the color change is observed by the naked eye and the absorbance is periodically transferred to a spectrophotometer for detection. However, the existing method has obvious defects. It lacks a dedicated fixing structure, the test tubes are easy to tip over, and the sample spacing cannot be guaranteed to be consistent, resulting in uneven contact of light and temperature. This problem ultimately leads to poor repeatability of experimental data, large comparison error, and difficulty in accurately reflecting the actual antioxidant activity of corn silk polysaccharide. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a comparative observation box for the antioxidant experiment of corn silk polysaccharide, which aims to improve the problems of the lack of a dedicated fixing structure, easy tipping of test tubes, and inability to ensure consistent sample spacing in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a comparative observation box for the antioxidant effects of corn silk polysaccharides, comprising a support box, a turntable rotatably connected to the inner wall of the support box, a fixed rod fixedly connected to the bottom of the turntable, a rotating shaft fixedly connected to the outer wall of the fixed rod, the outer wall of the rotating shaft fixedly connected to the inner wall of the support box, a connecting rod fixedly connected to the inner wall of the fixed rod, a driven bevel gear fixedly connected to the outer wall of the connecting rod, a driving bevel gear meshing with the inner wall of the driven bevel gear, a fixed connecting rod fixedly connected to the inner wall of the driving bevel gear, a connecting plate fixedly connected to the front side of the fixed connecting rod, a handle fixedly connected to the front side of the connecting plate, and multiple clamping mechanisms fixedly connected to the top of the turntable, the clamping mechanisms being used to clamp tubes of different types.

[0006] As a further description of the above technical solution:

A fixed plate is fixedly connected to the bottom of the spring. A load-bearing column is fixedly connected to the top of the spring. Each pair of clamps is fixedly connected to a sleeve.

[0030] 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.

[0031] Please see the appendix Figure 1 and attached Figure 4 An embodiment of this utility model provides: a comparative observation box for the antioxidant effect of corn silk polysaccharide, including a support box 1, a turntable 3 rotatably connected to the inner wall of the support box 1, a fixed rod 4 fixedly connected to the bottom of the turntable 3, a rotating shaft 5 fixedly connected to the outer wall of the fixed rod 4, the outer wall of the rotating shaft 5 being fixedly connected to the inner wall of the support box 1, a connecting rod 6 fixedly connected to the inner wall of the fixed rod 4, a driven bevel gear 7 fixedly connected to the outer wall of the connecting rod 6, a driving bevel gear 8 meshing with the inner wall of the driven bevel gear 7, a fixed connecting rod 9 fixedly connected to the inner wall of the driving bevel gear 8, a connecting plate 10 fixedly connected to the front side of the fixed connecting rod 9, a handle 11 fixedly connected to the front side of the connecting plate 10, and multiple clamping mechanisms 2 fixedly connected to the top of the turntable 3, the clamping mechanisms 2 being used to clamp tubes of different types;

[0032] Specifically, the support box 1 serves as the basic load-bearing structure, providing stable support for the entire device. The turntable 3, rotatably connected to its inner wall, can rotate flexibly with the help of the bottom fixed rod 4 and the outer wall rotating shaft 5. The rotating shaft 5 is fixed to the inner wall of the support box 1 to ensure rotational stability. The connecting rod 6 on the inner wall of the fixed rod 4 meshes with the driving bevel gear 8 through the driven bevel gear 7 on the outer wall. The fixed connecting rod 9 on the inner wall of the driving bevel gear 8 cooperates with the front connecting plate 10 and the handle 11. When the experimenter turns the handle 11, the turntable 3 can be rotated, making it convenient to observe the sample placed on top of the turntable 3 from different angles without manually adjusting the tube position. The multiple clamping mechanisms 2 on the top of the turntable 3 can be adapted to and clamp different types of tubes to ensure the stability of the tubes during the experiment and avoid the impact of shaking on the reaction and observation. This helps to accurately carry out the comparative experiment on the antioxidant properties of corn silk polysaccharide, making sample placement, angle adjustment and observation operations more convenient and efficient.

[0033] Please see the appendix Figure 3 and attached Figure 5 The clamping mechanism 2 includes a limiting column 201, the bottom of which is fixedly connected to the top of the turntable 3. Multiple clamps 207 are slidably connected to the inner wall of the limiting column 201. Each pair of clamps 207 is rotatably connected to a limiting column 206. Each pair of limiting columns 206 is fixedly connected to a limiting cover 204. A spring 203 is slidably connected to the inner wall of the limiting cover 204. A fixed plate 202 is fixedly connected to the bottom of the spring 203. A load-bearing column 205 is fixedly connected to the top of the spring 203. Each pair of clamps 207 is fixedly connected to a clamp sleeve 208.

[0034] Specifically, the clamping mechanism 2 is key to the observation box's adaptability to various test tubes 18. The limiting column 201 is vertically fixed to the turntable 3, providing an installation base for the clamp 207. Multiple clamps 207 sliding on the inner wall, together with adjacent rotating limiting columns 206, can flexibly adjust the spacing. The limiting cover 204, spring 203, fixing plate 202, and load-bearing column 205 form an elastic adjustment structure. When the spring 203 is compressed or rebounds, it drives the clamps 207 to open and close, adapting to test tubes 18 of different diameters. The sleeve 208 enhances the clamping stability, allowing the device to fix various types of test tubes 18, meeting the needs of simultaneous testing of multiple samples in the corn silk polysaccharide antioxidant experiment, ensuring the stability of the test tube 18 position during the experiment, and facilitating accurate comparative observation.

[0035] Please see the appendix Figure 1 and attached Figure 2 A transparent cover 12 is fixedly connected to the top of the support box 1, a bracket 13 is fixedly connected to the bottom of the support box 1, a protective shell 14 is fixedly connected to the bottom of the support box 1, a sealing cover 15 is rotatably connected to the top of the support box 1, an observation window 16 is opened on the inner wall of the sealing cover 15, and a timer 17 is fixedly connected to the inner wall of the support box 1.

[0036] Specifically, the transparent cover 12 on the top of the support box 1 allows observation of the internal experiment, the bottom bracket 13 provides stable support for the whole, the protective shell 14 protects the internal components, the top sealing cover 15 can be closed to form a closed environment, the observation window 16 on the inner wall facilitates observation during the reaction, and the timer 17 on the inner wall can record the reaction time to ensure uniform experimental time and help to conduct the corn silk polysaccharide antioxidant comparison experiment accurately.

[0037] Please see the appendix Figure 2 and attached Figure 3 A heating rod 19 is fixedly connected to the inner wall of the support box 1, a temperature display 22 is fixedly connected to the inner wall of the support box 1, a storage box 20 is fixedly connected to the inner wall of the support box 1, a funnel 21 is fixedly connected to the top of the storage box 20, test tubes 18 are slidably connected between adjacent jackets 208, and the bottom of the fixed plate 202 is fixedly connected to the top of the turntable 3.

[0038] Specifically, the heating rod 19 on the inner wall of the support box 1 can adjust the internal temperature, and the temperature display 22 can be used to intuitively monitor the temperature and ensure a stable reaction environment. The storage box 20 and the top funnel 21 facilitate the storage and injection of reagents. The test tube 18 slidably connected between the jackets 208 is used to load samples. The fixed plate 202 and the turntable 3 are fixed to enhance the overall stability and help to carry out the corn silk polysaccharide antioxidant experiment efficiently.

[0039] Working principle: First, based on the support box 1, the handle 11 is rotated by human power, which in turn drives the handle 11 fixed to it. Then, through the drive bevel gear 8 on it, the driven bevel gear 7 and the connecting rod 6 on it are rotated. By using the rotating shaft 5 and the inner wall of the support box 1, the fixed rod 4 and the turntable 3 are rotated. This makes the rotation easy to observe, reduces manual operation, lowers the cost of use, and improves the efficiency of use.

[0040] First, the test tube 18 is placed on the support column 205. Gravity presses down the limiting cover 204 and the spring 203, which in turn drives the limiting column 206 on the limiting cover 204. Then, the limiting hole on the limiting connecting column 201 is used to tighten the clamp 207 upward, thereby clamping test tubes 18 of different models, reducing the cost of use and improving practicality.

[0041] 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.
