Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to the detection of dark boxes using the RGB colorimetric method. Background Technology

[0002] As the RGB colorimetric method evolves towards portability and rapid on-site testing, the demand for darkrooms is further upgraded. Traditional darkrooms are bulky, complex to operate, and difficult to adapt to on-site scenarios. They also lack modular compatibility with portable imaging devices, failing to meet the need for plug-and-play rapid testing. Therefore, developing a dedicated RGB colorimetric testing darkroom with efficient light shielding, standardized light source, precise temperature control, and portability is key to solving the pain points of existing technologies and promoting the standardized application of the RGB colorimetric method.

[0003] Existing testing instruments have high maintenance costs, require professional operators and complex sample processing procedures, which greatly limits their application in on-site testing. Furthermore, traditional instruments are often bulky and heavy, causing significant inconvenience during handling or transfer and making it difficult to flexibly adapt to the needs of mobile scenarios.

[0004] Therefore, there is an urgent need to provide an RGB colorimetric method for detecting dark boxes to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an RGB colorimetric method for detecting dark boxes.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution: providing an RGB colorimetric detection dark box, including a U-shaped mounting frame, on which a splicing component is mounted, and a connecting plate is slidably connected to the front end of the U-shaped mounting frame; The rear end of the U-shaped mounting frame has two guide grooves, and the splicing component has a sliding groove. A baffle is slidably connected between the splicing component and the slide groove, and the splicing component enables the quick assembly and disassembly of the dark box.

[0007] The present invention is further configured such that: the splicing component includes a plurality of first inlay slots opened on one side of the U-shaped mounting frame; two guide strips are fixedly connected to the front end of the U-shaped mounting frame; a plurality of second inlay slots are opened on the other side of the U-shaped mounting frame; a first inlay block is slidably connected to the inner side of each of the plurality of first inlay slots; a first sealing plate is fixedly connected between the inner sides of the plurality of first inlay blocks; a rectangular groove is opened on the first sealing plate; a second inlay block is slidably connected to the inner side of each of the plurality of second inlay slots; a second sealing plate is fixedly connected between the inner sides of the plurality of second inlay blocks; and a third inlay slot is opened at the lower end of the U-shaped mounting frame near the first inlay slot.

[0008] Using the above technical solution, the first inlay block on the first sealing plate is aligned with the first inlay groove on one side of the U-shaped mounting frame. The first sealing plate is slowly pushed along the extension direction of the first inlay groove so that all the first inlay blocks are completely slid into the first inlay groove, ensuring that the plate fits tightly with the U-shaped mounting frame. Then, the second inlay block on the second sealing plate is aligned with the second inlay groove on the other side of the U-shaped mounting frame. The second sealing plate is slid along the direction of the second inlay groove so that the second inlay block is completely inserted into the second inlay groove, completing the assembly of the sealing structures on both sides. Then, the connecting plate is slowly pushed in along the direction of the guide strip so that the connecting plate matches the edge structure of the U-shaped mounting frame, the first sealing plate, and the second sealing plate, completing the closure of the overall frame. Finally, the baffle is inserted along the direction of the third inlay groove to ensure that it fits tightly with the bottom of the U-shaped mounting frame, forming a bottom closed structure.

[0009] The present invention is further configured such that: two first inlay slots and two second inlay slots are provided on both sides of the rear end of the connecting plate, and the first inlay slots and the second inlay slots are matched with the corresponding first inlay block and the second inlay block.

[0010] With the above technical solution, during assembly, the connecting plate can be quickly aligned along the extension direction of the first and second inlay blocks, which greatly reduces the difficulty of manual alignment and shortens the assembly time. At the same time, the inlay fit naturally restricts the lateral offset of the connecting plate, ensuring that it is completely fitted with the edges of the U-shaped mounting frame, the first sealing plate and the second sealing plate, thus improving the assembly accuracy.

[0011] The present invention is further configured such that the inner sides of both guide grooves are fitted with the outer sides of the corresponding guide strips, and the two guide grooves and guide strips are parallel to each other.

[0012] Through the above technical solution, the tight fit between the guide groove and the guide strip forms a rigid positioning reference, which ensures that the connecting plate always maintains a straight motion trajectory during the advancement process, and can also prevent the deformation or breakage of the first sealing plate and the second sealing plate due to local overload.

[0013] The present invention is further configured such that the inner sides of the third inlay groove and the sliding groove are matched with the outer side of the baffle, and the baffle and the U-shaped mounting frame are arranged perpendicularly.

[0014] Through the above technical solution, the precise matching between the third inlay groove and the inner side of the slide groove ensures that the gap between the baffle and the U-shaped mounting frame is close to zero when the baffle is sliding or fixed, and the baffle is set perpendicular to the U-shaped mounting frame. This structure can effectively distribute external loads.

[0015] The present invention is further configured such that the U-shaped mounting frame, the first inlay block, the second sealing plate and the connecting plate are all designed with a three-layer composite structure, and the materials from the outer layer to the inner layer are PETG, thermal insulation material and black light-absorbing material respectively.

[0016] Through the above technical solution, the outer PETG layer provides UV protection, the middle insulation material forms a thermal resistance barrier, and the inner black light-absorbing material eliminates stray light and enhances thermal radiation efficiency.

[0017] The present invention is further configured such that: the baffle passes through the first inlay block, and the top of the baffle fits with the upper inner side of the U-shaped mounting frame.

[0018] Through the above technical solutions, a rigid connection system is formed. The through-hole design allows the baffle and the first inlay block to be linked by force, and the top fits to restrict vertical displacement, thus jointly improving the overall structure's resistance to deformation and dispersing external impact.

[0019] The beneficial effects of this utility model are as follows: 1. This utility model can be disassembled into independent modules by setting splicing components, which greatly reduces the volume and weight after disassembly, making it easy to pack into a portable case and carry to non-laboratory scenarios such as fields and on-site water quality monitoring points. No professional tools are required for assembly, and it can be quickly assembled to meet the needs of rapid detection for immediate deployment. 2. This utility model adopts a three-layer composite structure design by setting a U-shaped mounting frame, a first inlay block, a second sealing plate and a connecting plate. The outer PETG layer provides UV protection, the middle insulation material forms a thermal resistance barrier, and the inner black light-absorbing material eliminates stray light and enhances thermal radiation efficiency.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 7 The RGB colorimetric detection darkroom includes a U-shaped mounting frame 1, on which a splicing component 2 is mounted. The splicing component 2 includes multiple first inlay slots 201 on one side of the U-shaped mounting frame 1. Two guide strips 202 are fixedly connected to the front end of the U-shaped mounting frame 1. Multiple second inlay slots 203 are opened on the other side of the U-shaped mounting frame 1. First inlay blocks 204 are slidably connected to the inner sides of each of the multiple first inlay slots 201. A first sealing plate 205 is fixedly connected between the inner sides of the multiple first inlay blocks 204. A rectangular groove 206 is opened on the first sealing plate 205. Second inlay blocks 207 are slidably connected to the inner sides of each of the multiple second inlay slots 203. A second sealing plate 208 is fixedly connected between the inner sides of the multiple second inlay blocks 207. A third inlay slot 209 is opened at the lower end of the U-shaped mounting frame 1 near the first inlay slots 201. The first inlay blocks 204 on the first sealing plate 205 are connected to the first inlay slots 201 on one side of the U-shaped mounting frame 1. Align the first sealing plate 205 along the extension direction of the first inlay groove 201, and slowly push it so that all the first inlay blocks 204 slide completely into the first inlay groove 201, ensuring that the plate fits tightly with the U-shaped mounting frame 1. Then, align the second inlay block 207 on the second sealing plate 208 with the second inlay groove 203 on the other side of the U-shaped mounting frame 1, and slide the second sealing plate 208 along the direction of the second inlay groove 203 so that the second inlay block 207 is completely inserted into the second inlay groove 203, completing the assembly of the sealing structure on both sides. Then, slowly push the connecting plate 3 along the direction of the guide strip 202 so that the connecting plate 3 matches the edge structure of the U-shaped mounting frame 1, the first sealing plate 205 and the second sealing plate 208, completing the closure of the overall frame. Finally, push along the third inlay groove 20... A baffle 6 is inserted in 9 directions to ensure a tight fit with the bottom of the U-shaped mounting frame 1, forming a closed bottom structure. A connecting plate 3 is slidably connected to the front end of the U-shaped mounting frame 1. Two first inlay grooves 201 and two second inlay grooves 203 are opened on both sides of the rear end of the connecting plate 3. The first inlay grooves 201 and the second inlay grooves 203 are matched with the corresponding first inlay blocks 204 and second inlay blocks 207. During assembly, the connecting plate 3 can be quickly aligned along the extension direction of the first inlay blocks 204 and the second inlay blocks 207, which greatly reduces the difficulty of manual alignment and shortens the assembly time. At the same time, the inlay fit naturally restricts the lateral displacement of the connecting plate 3, ensuring that it is completely fitted with the edges of the U-shaped mounting frame 1, the first sealing plate 205 and the second sealing plate 208, and improving the assembly accuracy. like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the rear end of the U-shaped mounting frame 1 has two guide grooves 4. The inner sides of the two guide grooves 4 are matched with the outer sides of the corresponding guide strips 202, and the two guide grooves 4 and the guide strips 202 are parallel to each other. The tight fit between the guide grooves 4 and the guide strips 202 forms a rigid positioning reference, ensuring that the connecting plate 3 maintains a straight trajectory during the advancement process. It also prevents the first sealing plate 205 and the second sealing plate 208 from deforming or breaking due to local overload. The splicing component 2 has a sliding groove 5, and a baffle 6 is slidably connected between the splicing component 2 and the sliding groove 5. The inner sides of the third inlay groove 209 and the sliding groove 5 are matched with the outer sides of the baffle 6, and the baffle 6 is perpendicular to the U-shaped mounting frame 1. The precise matching between the inner sides of the third inlay groove 209 and the sliding groove 5 ensures that the baffle 6 is perpendicular to the U-shaped mounting frame 1 when sliding or fixed. With the gap approaching zero and the baffle 6 perpendicular to the U-shaped mounting frame 1, this structure effectively disperses external loads. The splicing component 2 enables quick assembly and disassembly of the dark box. The U-shaped mounting frame 1, the first inlay block 204, the second sealing plate 208, and the connecting plate 3 all adopt a three-layer composite structure design. The materials from the outer layer to the inner layer are PETG, thermal insulation material, and black light-absorbing material, respectively. The outer PETG layer provides UV protection, the middle thermal insulation material forms a thermal resistance barrier, and the inner black light-absorbing material eliminates stray light and enhances thermal radiation efficiency. The baffle 6 penetrates the first inlay block 204, and the top of the baffle 6 fits with the upper inner side of the U-shaped mounting frame 1, forming a rigid connection system. The through-hole design allows the baffle 6 and the first inlay block 204 to be linked by force, and the top fit restricts vertical displacement, jointly improving the overall structure's resistance to deformation and dispersing external impacts.

[0024] In use, the first insert block 204 on the first sealing plate 205 is aligned with the first insert groove 201 on one side of the U-shaped mounting frame 1. The first sealing plate 205 is then slowly pushed along the extending direction of the first insert groove 201, allowing all the first insert blocks 204 to slide completely into the first insert groove 201, ensuring a tight fit between the plate and the U-shaped mounting frame 1. Then, the second insert block 207 on the second sealing plate 208 is aligned with the second insert groove 203 on the other side of the U-shaped mounting frame 1. The second sealing plate 208 is slid along the direction of the second insert groove 203, allowing the second insert block 207 to fully engage with the second insert groove 203, completing the assembly of the sealing structures on both sides. Finally, the connecting plate 3 is slowly pushed forward along the direction of the guide strip 202. The connecting plate 3 is adapted to the edge structure of the U-shaped mounting frame 1, the first sealing plate 205 and the second sealing plate 208 to complete the overall frame closure. Finally, the baffle 6 is inserted along the direction of the third inlay groove 209 to ensure that it fits tightly with the bottom of the U-shaped mounting frame 1 to form a bottom closed structure. Then, the operable part of the dark box is opened, and the sample to be tested for RGB colorimetric analysis is placed in the detection core area where the rectangular groove 206 is located inside the dark box. After placement, the dark box is closed and the closed state is restored. Then, the RGB detection equipment is used inside the dark box to perform colorimetric analysis on the sample.
