Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to an analytical reagent addition device for food testing. Background Technology

[0002] Food testing refers to the process of using physical, chemical, and biological methods to detect and analyze nutrients, additives, contaminants, and harmful substances in food. Its purpose is to ensure food quality and safety and protect consumer health. The addition of reagents in food testing is a crucial step in the process, directly affecting the accuracy and reliability of the test results. Improper addition of reagents during testing may lead to deviations in test results, affecting the correct assessment of food quality. Strictly following standard operating procedures for reagent addition is key to ensuring accurate, stable, and repeatable food testing results.

[0003] Existing analytical reagent addition devices for food testing have some shortcomings. Experimenters are prone to instability when handling the reaction vessel by hand, and manually shaking the reagents in the reaction vessel can cause hand fatigue and may also lead to incomplete reagent reactions, affecting the accuracy and reliability of the test results. To solve these problems, we propose an analytical reagent addition device for food testing. Utility Model Content

[0004] The main objective of this invention is to provide an analytical reagent addition device for food testing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An analytical reagent addition device for food testing includes a base plate, a clamping mechanism at the upper end of the base plate, a moving mechanism at the rear end of the clamping mechanism, and a second support plate at the rear end of the moving mechanism. The lower end of the second support plate is fixedly connected to the base plate. The clamping mechanism includes an operating table, a first limiting block and a fixing block are fixedly connected to the upper end of the operating table, a threaded rod is threadedly connected to the inner side of the fixing block, and a second limiting block is rotatably connected to one end of the threaded rod. The second limiting block is slidably connected to the upper end of the operating table and is located between the first limiting block and the fixing block. The moving mechanism includes a first slider.

[0007] Preferably, a workbench is fixedly connected to the upper end of the base plate, the lower end of the operating table is slidably connected to the workbench, a first support plate is fixedly connected to the upper end of the first limiting block, and a sealing cover is connected to the upper end of the first support plate through a damping rotating shaft.

[0008] Preferably, two sets of sliding rods are slidably connected to the inner side of the fixing block. The two sets of sliding rods are symmetrical to each other. A spring is wound around the outer side of the sliding rod. The sliding rod passes through the fixing block and is fixedly connected to the second limiting block.

[0009] Preferably, a workbench is fixedly connected to the upper end of the base plate, a fixing plate is fixedly connected to the upper end of the workbench, an opening is provided on the inner side of the fixing plate, the first slider is slidably connected to the inner side of the opening, and the front end of the first slider is fixedly connected to the operating table.

[0010] Preferably, a vertical rod is fixedly connected to the rear end of the first slider, a groove is provided on the inner side of the vertical rod, a second slider is slidably connected to the inner side of the groove, and a first rotating block is fixedly connected to the rear end of the second slider.

[0011] Preferably, a rotating rod is rotatably connected to the outer side of the first rotating block, and a second rotating block is fixedly connected to the rear end of the rotating rod. The second rotating block is rotatably connected to the second support plate.

[0012] Preferably, a motor is installed at the rear end of the second support plate, the output end of the motor passes through the second support plate and is fixedly connected to the second rotating block, a top plate is fixedly connected to the upper end of the second support plate, and a liquid storage tank is fixedly connected to the inner side of the top plate.

[0013] Compared with the prior art, this utility model has the following beneficial effects: In use, the reaction container containing the sample is first placed between the first and second limiting blocks. The threaded rod is rotated, and the second limiting block is pushed closer to the first limiting block via the screw principle, thus fixing the reaction container. The storage tank is opened to add the analytical reagent. After addition, the sealing cap is rotated and placed on the reaction container to effectively prevent reagent evaporation or leakage. Then, the motor is started, driving the second rotating block to rotate, which in turn causes the rotating rod to rotate around the second rotating block as an axis. During this process, the rotating rod, through its rotational connection with the first rotating block, can drive the second slider to slide within the groove, thereby causing the upright to move back and forth in the horizontal direction. The clamping mechanism, fixedly connected to the upright via the first slider, moves along with the upright, thus moving the reaction container and ensuring sufficient contact and reaction between the reagent and the sample. This utility model can securely clamp and fix the reaction container through the clamping mechanism when adding reagents, and after adding reagents, the reaction container can be moved and shaken back and forth by the moving mechanism to ensure sufficient contact and reaction between the reagent and the sample, thereby ensuring the accuracy of the test results.

A spring 38 is wound around the outer side of the slide rods 37. The slide rods 37 pass through the fixing block 35 and are fixedly connected to the second limiting block 39.

[0026] Specifically, rotating the threaded rod 36 causes the second limiting block 39 to move closer to the first limiting block 32 via the screw principle, thereby fixing the reaction vessel.
