Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of reagent combination structures, and in particular relates to a reagent combination structure. Background Art
[0002] Common colloidal gold reagents mainly include a shell made of PVC material and a test paper detection membrane assembled inside the shell. The shell includes a bottom plate and a top cover that are interlocked with each other. The top cover is usually provided with a sample addition hole and an observation hole. Since the detection membrane is usually made of soft fiber and has a small thickness, the detection membrane needs to be placed in the bottom plate during assembly, and then the top cover is closed. Since there is no limiting structure for the detection membrane inside the existing shell, the detection membrane is prone to warping, wrinkling, and deflection when the top cover is closed, which ultimately causes the detection membrane to be unable to be smoothly unfolded at the bottom of the sample addition hole and the observation hole, affecting the use of the reagent. Utility Model Content
[0003] In order to solve the deficiencies of the prior art, the utility model provides a reagent combination structure, which can effectively prevent the detection film from warping, wrinkling, deflection and other problems, and improve the assembly quality of the reagent.
[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:
[0005] A reagent combination structure comprises a bottom plate and a cover plate buckled on the top surface thereof, wherein the cover plate is provided with an observation hole and a sample addition hole, and a detection membrane is arranged between the bottom plate and the cover plate.
[0006] The top surface of the bottom plate has a groove, and the bottom surface of the groove is provided with multiple limit plates arranged in a rectangular structure. A buckle plate is provided on the side of the top of the limit plate facing the middle of the rectangular structure. The outer dimensions of the detection membrane match the rectangular structure formed between the limit plates, and the projections of the observation holes and the sample loading holes on the bottom plate are located within the range of the rectangular structure.
[0007] The bottom surface of the groove is arranged with burrs protruding upward, and the top of the burr is a sharp angle structure.
[0008] The bottom surface of the cover plate is provided with buckles corresponding to the limit plates one by one, and a convex strip is provided on the bottom of the buckle facing the outside of the cover plate. The bottom surface of the cover plate is provided with a pressure plate, which is located within the range surrounded by multiple buckles. The pressure plate is provided with through holes corresponding to the observation holes and the sample addition holes.
[0009] When assembled, the cover plate is buckled with the bottom plate, the convex strip is clamped at the bottom of the buckle plate, the detection membrane is located in the rectangular structure formed between the limit plates, the bottom surface of the detection membrane contacts the burr, and the pressure plate is pressed against the top surface of the detection membrane.
[0010] The beneficial effects of the utility model are as follows: the scheme utilizes the method of inserting burrs into the interior of the detection film to prevent the detection film from warping and preventing the detection film from falling off during the assembly process; the detection film is limited by a limiting plate, which can effectively prevent the detection film from deflecting, and the pressing plate can press the detection film down flatly to prevent the detection film from wrinkling.
