Description

Technical Field

[0001] This utility model relates to the technical field of light-shielding boxes for color development reactions, and more particularly to a light-shielding box used for color development reactions. Background Technology

[0002] A colorimetric reaction is a process in which a colorless or light-colored substance is transformed into a product with a distinct color change through a chemical or biochemical reaction. This color change is commonly used for qualitative detection, quantitative analysis, or visual observation, and is widely applied in fields such as chemical analysis, biological detection, and environmental monitoring.

[0003] The existing colorimetric reaction comparison method is a common judgment method in chemical detection. However, the colorimetric reaction comparison method requires the tester to observe with the naked eye. The usual observation of the titration colorimetric process is carried out directly indoors. Due to the lack of light-shielding components, the tester's observation of the titration colorimetric process is easily affected by the external light, which makes it easy for the tester to make deviations when comparing colors, resulting in inaccurate test results. Therefore, the existing method of observing the titration colorimetric reaction process is inconvenient. To address this, we provide a light-shielding box for colorimetric reactions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the observation of a titration colorimetric reaction process is easily affected by external light, and to provide a light-shielding box for colorimetric reactions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a light-shielding box for color development reaction, comprising: a light-shielding mechanism, the light-shielding mechanism including a base plate, a box body provided on the top of the base plate, a top cover provided on the top of the box body, a black sleeve layer fixedly connected inside one of the box bodies, a black pad layer fixedly connected to the bottom of one of the top covers, a white sleeve layer fixedly connected inside the other box body, a white pad layer fixedly connected to the bottom of the other top cover, a round hole provided on the box body, a viewing hole provided on the box body, a lamp body sleeved inside the box body, and an auxiliary mechanism provided on the top of the base plate.

[0006] In a preferred embodiment, there are two boxes, the top cover is fitted inside the box and is slidably connected to the box, the lamp body is fixedly connected to the base plate, and a comparison card is provided inside both the black and white sleeve layers, and the comparison card is fixedly connected to both the black and white sleeve layers.

[0007] In a preferred embodiment, the auxiliary mechanism includes a limiting block, which is fixedly connected to the base plate, and a sliding block is sleeved inside the housing.

[0008] In a preferred embodiment, the sliding block is slidably connected to the housing, and the sliding block has a groove.

[0009] In a preferred embodiment, one end of the sliding block is provided with a push rod, which is fixedly connected to the sliding block.

[0010] In a preferred embodiment, one end of the sliding block is provided with a push rod two, which is fixedly connected to the sliding block.

[0011] In a preferred embodiment, push rod one and push rod two are sleeved inside the box body, and push rod one and push rod two are slidably connected to the box body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, by incorporating a light-shielding mechanism, prevents the testing personnel from being affected by external light when observing and comparing titration colorimetric reactions, thereby improving the accuracy of the test results. It also features two chambers and two lids, each with a black sleeve and black pad, and a white sleeve and white pad, respectively. This provides two distinct testing environments. In the black environment, the testing personnel can more clearly observe the colorimetric reaction process and even subtle changes, aiding in the judgment of the test results. In the white environment, the uniform diffuse reflection reduces shadow interference, allowing for more accurate color comparison. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a light-shielding box for color development reaction, comprising: a light-shielding mechanism 1, the light-shielding mechanism 1 including a base plate 11, a box body 12 provided on the top of the base plate 11, a top cover 13 provided on the top of the box body 12, a black sleeve layer 14 fixedly connected inside one of the box bodies 12, a black pad layer 15 fixedly connected to the bottom of one of the top covers 13, a white sleeve layer 16 fixedly connected inside the other box body 12, a white pad layer 17 fixedly connected to the bottom of the other top cover 13, a round hole 18 opened on the box body 12, a viewing hole 19 opened on the box body 12, a lamp body 101 sleeved inside the box body 12, and an auxiliary mechanism 2 provided on the top of the base plate 11. There are two boxes 12. The top cover 13 is fitted inside the box 12 and is slidably connected to the box 12. The lamp body 101 is fixedly connected to the base plate 11. The black cover layer 14 and the white cover layer 16 are both equipped with comparison cards 102. The comparison cards 102 are fixedly connected to the black cover layer 14 and the white cover layer 16.

[0026] In this embodiment, by providing the housing 12 and the top cover 13, two enclosed spaces are provided for the titration colorimetric detection, thereby reducing the influence of external factors on the experiment. The black sheath 14 and black pad 15 effectively isolate one of the enclosed spaces from external light, ensuring that external light does not affect the observer's observation during the experiment. Simultaneously, the white sheath 16 and white pad 17 ensure more uniform diffuse reflection of the light provided by the lamp 101, preventing shadows from appearing within the enclosed space. The comparison between the color presented by the titration test and the comparison card 102 is more convenient, and the tester can make more accurate comparison and judgment of the color. In addition, round holes 18 are opened on both sides of the chamber 12, allowing the tester to put his / her hands into the chamber 12 and complete the titration and comparison process inside the chamber 12. A viewing hole 19 is opened on the chamber 12, allowing the tester to effectively observe the situation inside the chamber 12. When the tester's hands and head cover the round holes 18 and the viewing hole 19, it will not affect the test process inside the chamber 12.

[0027] Example 2

[0028] like Figures 1-4 As shown, the auxiliary mechanism 2 includes a limiting block 21, which is fixedly connected to the base plate 11. A sliding block 22 is sleeved inside the housing 12 and is slidably connected to the housing 12. A groove 23 is provided on the sliding block 22. A push rod 24 is provided at one end of the sliding block 22 and is fixedly connected to the sliding block 22. A push rod 25 is provided at one end of the sliding block 22 and is fixedly connected to the sliding block 22. The push rod 24 and the push rod 25 are sleeved inside the housing 12 and are slidably connected to the housing 12.

[0029] In this embodiment, by setting an auxiliary mechanism 2, the experimental apparatus used for titration colorimetric detection can be transferred to the interior of another box 12. By setting a limiting block 21, the sliding block 22 will not deviate when passing between the two boxes 12, and can move accurately to the interior of the other box 12 under the restriction of the limiting block 21. By setting push rod 1 24 and push rod 25, the testing personnel can easily control the sliding block 22, and thus complete the transfer of the sliding block 22 more conveniently.

[0030] Working principle:

[0031] like Figures 1-4As shown, in use, the experimental apparatus for titration color development can be placed inside the groove 23 on the sliding block 22. The sliding block 22 and groove 23 are then placed inside a box 12 fitted with a black sleeve 14. The top cover 13 is then placed over the top of the box 12. The operator then inserts both hands into the box 12 through the round holes 18 on both sides, placing their eyes at the viewing hole 19 and covering the viewing hole 19 with their head. The lamp 101 is then turned on to provide supplemental lighting, allowing the operator to effectively observe subtle color changes during the titration color development process without being affected by external light. When the titration color development process reverses... After the reaction is complete, the experimental apparatus placed in the groove 23 on the sliding block 22 can be transferred using the auxiliary mechanism 2, moving it into the interior of a box 12 with a white cover layer 16 installed. At this time, push rod 1 24 is pushed, causing the sliding block 22 to gradually detach from the box 12 and slide within the limiting block 21. Then, push rod 25 is used to continue pulling the sliding block 22 until the sliding block 22 and the experimental apparatus are completely inside another box 12, with push rod 25 positioned on the outside of the box 12. At this time, the lamp 101 is turned on, and the testing personnel can use the same method to compare the colors produced by the colorimetric reaction and make a precise comparison with the comparison card 102, thereby obtaining a more accurate conclusion.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
