Technical Field

[0001] The present invention relates to the technical field of detection devices, in particular to a food rapid detection kit and a detection reagent thereof. Background Art

[0002] With the continuous development of social economy, people are paying more and more attention to food quality and safety. This has also continuously urged relevant departments such as food supervision and management to play their role and strengthen food inspection to ensure that people eat safe and reliable food. When relevant supervisory departments conduct on-site food testing, they extract the food test substances and react them with the corresponding test reagents on the test paper card in the test kit. Finally, based on the experimental phenomena and comparison with the corresponding standards, the experimental conclusions are drawn.

[0003] In order to facilitate staff to more intuitively observe the reaction of reagents in test tubes, existing test kits are only provided with a layer of test tube holders in the test kit to hold test tubes containing reagents. As a result, the number of reagents stored in each test kit is small. When conducting multiple types of food testing, multiple test kits need to be carried, which is costly to use. At the same time, it is difficult to quickly eject the support plate, which causes the reagent tubes to be exposed, making it inconvenient for testers to use. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-7As shown, the embodiment of the present invention provides a food rapid detection kit, including a box body 3, a sealing cover 1 is fixedly provided on the upper end surface of the box body 3, through holes 2 are provided on both sides of the upper end surface of the sealing cover 1, and detection boxes 5 are embedded in the lower ends of both sides of the box body 3, a slide groove 6 is provided on one side of the two detection boxes 5 near the upper end, and a fixing mechanism 4 is embedded in the slide groove 6, a driving motor 13 is fixedly provided at the lower end of the box body 3, and a rotating plate 25 is fixedly connected to the output end of the driving motor 13, electric telescopic rods 26 are fixedly provided on both sides of the upper end surface of the rotating plate 25, and a clamping plate 23 is fixed on the upper end surface of the two electric telescopic rods 26, and a detection box 12 is embedded in the two detection boxes 5;

[0033] A rotating seat 11 is rotatably provided at the lower end of the inner side of the box body 3, a shaft 21 is fixedly provided at the midpoint of the lower end surface of the rotating seat 11, a connecting column 7 is fixedly provided at the midpoint of the upper end surface of the rotating seat 11, mounting seats 10 are movably provided on both sides of the upper end surface of the rotating seat 11 and reagent kits 9 are fixedly provided on the upper end surfaces of the mounting seats 10, top covers 8 are fixedly provided on the upper end surfaces of the two reagent kits 9, screws 17 are rotatably provided on both sides of the inside of the connecting column 7 and a transmission rod 18 is rotatably provided at the midpoint near the lower end, a number one gear 19 and a number two gear 20 are fixedly sleeved on the outer sides of the two screws 17 and the outer sides of the transmission rod 18, and a clamping block 27 is fixedly connected to the lower end of the transmission rod 18.

[0034] When using the detection kit 9 for inspection, the detection boxes 12 on both sides are selected for inspection according to the number and purpose of the detection targets. At this time, the linkage plate 403 is pressed down first. During the process of pressing the linkage plate 403, the limiting block 401 and the limiting spring 402 are pulled to move. At this time, the limiting block 401 disengages from the sliding groove 15 to release the fixation of the detection box 5. The detection box 5 is pulled out to expose the detection box 12 in the upper end. At this time, according to the target to be detected, the appropriate reagent is selected from the reagent kit 9 and the target to be detected is placed on the detection box 12 to complete the rapid detection.

[0035] When taking the reagent, the electric telescopic rod 26 is first used to push the clamping plate 23 upward. Since the lower end of the shaft 21 is fixed with protrusions on both sides and the two protrusions are rectangular, the clamping groove 22 at the upper end of the clamping plate 23 is adapted to be clamped therewith, so that it is connected with the shaft 21 and prompts the clamping block 27 at the lower end of the transmission rod 18 to pass through the through groove 24. Since the through groove 24 is rectangular and adapted to the clamping block 27, when the clamping block 27 passes through the through groove 24, the rotation of the clamping plate 23 will not drive the transmission rod 18 to rotate, but only complete the rotation of the shaft 21; at this time, the drive motor 13 is started to drive the clamping plate 23 to rotate, thereby driving the shaft 21 to rotate, and then driving the rotating seat 1 at the upper end 1 rotates, and at this time the reagent box 9 at the upper end rotates along with the connecting column 7 so that it moves to the position of the through hole 2 of the cover 1. After the rotation adjustment is completed, the electric telescopic rod 26 is started again to move downward so that the shaft 21 is disengaged from the clamping plate 23, and the clamping block 27 is embedded in the through groove 24 to complete the clamping connection. At this time, the driving motor 13 drives the transmission rod 18 to rotate, and the transmission rod 18 and the two screw rods 17 are connected by the first gear 19 and the second gear 20. The transmission rod 18 is rotated through the fixing member 16 and is set in the connecting column 7 and passes through the lower end surface of the shaft 21, thereby completing the linkage rotation, thereby causing the mounting seat 10 with the outer thread sleeve to move upward, thereby pushing out the reagent box 9;

[0036] After the reagent box 9 is pushed out from the through hole 2 at the upper end, the user uses the sealing mechanism 14 to press the connecting rod 1402 to drive the inner block 1401 and the connecting spring 1403 to move downward, and the block 1401 is disengaged from the box door 904 at the front end of the shell 901 of the reagent box 9. At this time, the box door 904 is flipped over, and the box door 904 rotates along the rotating shaft 903 to complete the flip and open. The interior is divided into different spaces by multiple partition plates 902, and each box door 904 is provided with a sticker 905 on the upper end. The sticker 905 is marked with the name of the reagent. At this time, the reagents in different spaces can be selected for use as needed. The detection reagents used in the detection kit 9 include extraction solvents, color developers and interference removal reagents. The extraction solvents include acidic aqueous solutions and organic solvents respectively. The color developers include trinitrophenol solution and sulfuric acid solution. The interference removal reagent is 0.01-0.2 mol / L potassium permanganate solution. The acidic aqueous solution includes hydrochloric acid, sulfuric acid, phosphoric acid, perchloric acid or nitric acid.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
