Description

Technical Field

[0001] The utility model relates to the technical field of extraction kits, and in particular to an extraction kit for detecting agricultural and animal residues. Background Art

[0002] A test kit is a container specially designed to hold various chemical reagents. They can contain all necessary reagents for detecting or analyzing specific compounds, pathogens (such as bacteria, viruses), drug residues, DNA, RNA or other biological molecules. An "extraction kit" is a tool kit specially designed to extract target molecules from different types of biological samples; crops and poultry are processed to become food that people often eat in their daily lives. In order to ensure people's health, crops and poultry need to undergo strict quality inspection before packaging and processing.

[0003] The harmful substances remaining in crops need to be strictly inspected, and only after they meet the standards can they enter the market for people to buy and eat. In the detection of agricultural and animal residues in poultry, various reagents are needed to detect the harmful substances remaining in poultry meat; especially in most poultry breeding environments, plastic products are widely used. The plasticizers and plasticizers contained in them are added to plastics or rubbers through chemical reactions or physical mixing to improve the flame retardancy and flexibility of plastics or rubbers. However, the corresponding plasticizers and plasticizers will also enter the animal body through feed, water, air and other channels, interfering with the animal's endocrine, metabolism, reproduction and other functions, thereby affecting the animal's growth, development and health, making the detection of agricultural and animal residues in poultry more strictly controlled.

[0004] Existing test cards and reagents for crops and poultry need to be placed in special test kits. Most of the test kits currently used on the market have poor protection for the reagent tubes inside. When encountering bumps on the road, the test tubes will shake up and down in the test kit, which will have a certain impact on the subsequent experimental results extracted in the reagent tubes. Utility Model Content

[0005] In order to overcome the shortcomings of the existing reagent kits that have poor protection for reagent tubes, the reagent tubes may shake up and down when encountering road bumps, thus affecting subsequent experimental results, the utility model provides an extraction kit for detecting agricultural and veterinary residues.

[0006] The technical solution of the utility model is: an extraction kit for detecting agricultural and veterinary residues, comprising a kit body, a kit cover, a reagent tube tray, a mounting plate, a spring, a clamping plate and a test tube, a kit cover is arranged on the top of the kit body, a reagent tube tray is clamped on the inner side of the kit body, mounting plates are symmetrically arranged in the reagent tube tray, springs are arranged on the inward side of the mounting plates, clamping plates are arranged on the inward side of the springs, test tubes are movably arranged in the placement holes of the reagent tube tray, and the test tubes are in contact and cooperate with the clamping plate.

[0007] Optionally, a hinge is further included, and the hinge is symmetrically arranged on the same side adjacent to the reagent kit body and the reagent kit cover.

[0008] Optionally, a knob lock and a buckle are also included. The knob lock is symmetrically arranged on one side of the reagent box body, and the buckle is symmetrically rotatably arranged on one side of the reagent box cover. The knob lock and the buckle are engaged by snap connection and rotation.

[0009] Optionally, a handle is also included, and the handle is fixedly arranged on the top of the reagent kit cover.

[0010] Optionally, an anti-skid ring and an anti-skid pad are also included. The anti-skid ring is provided on the outer side of the middle part of the handle, and the anti-skid pad is provided on the bottom of the reagent kit body.

[0011] Optionally, a sealing ring is also included, and a sealing ring is arranged at the bottom of the inner part of the reagent kit cover.

[0012] The beneficial effect of the utility model is that the bottom of the test tube is squeezed onto the top of the clamping plate, so that the clamping plate moves inward along the slide groove in the reagent tube tray, and the spring is squeezed by the clamping plate to be deformed and shortened. When the test tube is placed, the test tube no longer squeezes the clamping plate and the spring is reset without force, and the clamping plate is driven to move outward. When the clamping plate moves, the outer side of the test tube is clamped by the extension force of the spring, so that the test tube does not shake when passing through a bumpy road section, thereby achieving the effect of avoiding affecting the test results of the sample in the test tube.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0023] Embodiment: A kit for detecting agricultural and animal residues, such as Figure 1-Figure 8 As shown, it includes a reagent box body 1, a reagent box cover 2, a reagent tube tray 3, a mounting plate 4, a spring 5, a clamping plate 6 and a test tube 7. The reagent box body 1, the reagent box cover 2 and the reagent tube tray 3 are all made of high temperature resistant plastic material. The reagent box body 1 is provided with a reagent box cover 2 on the top, and the reagent tube tray 3 is clamped on the inner side of the reagent box body 1. When the reagent box tray 3 needs to be cleaned or replaced, it can be unplugged from the reagent box body 1 to cancel the clamping. The reagent tube tray 3 is provided with eight symmetrical placement holes, and the reagent tubes near the placement holes are placed on the reagent box body 1. The tray (3) is symmetrically provided with slide grooves inside, and four mounting plates 4 are symmetrically provided in the slide grooves inside the placement hole of the reagent tube tray 3. Springs 5 ​​are symmetrically provided on the outward side of the four mounting plates 4, and clamping plates 6 are provided on the outward side of the springs 5. The clamping plates 6 will approach and contact each other when the springs 5 ​​are in an extended state, and will move away from each other and will not contact each other when the springs 5 ​​are in a shortened state. The tops of the clamping plates 6 are chamfered, and a test tube 7 is movably provided in the placement hole of the reagent tube tray 3, and the test tube 7 is in contact with the clamping plates 6.

[0024] like Figure 2 and Figure 7As shown, a hinge 8 is also included. The reagent box body 1 and the reagent box cover 2 are provided with a hinge 8 on the same side adjacent to each other. The hinge 8 is used to assist the reagent box body 1 and the reagent box cover 2 in opening and closing operations.

[0025] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a knob lock 9 and a buckle 10. The front side of the knob lock 9 is a straight knob buckle. The front side of the reagent box body 1 is symmetrically provided with the knob lock 9 by screws, and the front side of the reagent box cover 2 is symmetrically provided with the buckle 10 by a rotating part. A buckle matching hole is opened on the lower side of the buckle 10. The buckle matching hole of the buckle 10 is snap-fitted with the knob buckle of the knob lock 9, and when the knob buckle of the knob lock 9 is twisted and rotated, the knob lock 9 will contact the front side of the buckle 10 and lock it to ensure the safety of the reagent box body.

[0026] like Figure 1-Figure 2 and Figure 8 As shown, a handle 11 is also included. A straight handle 11 is provided on the top of the reagent kit cover 2 by means of screws. The handle 11 is an auxiliary component that provides a carrying function for the entire reagent kit based on the hinge 8, the knob lock 9 and the buckle 10.

[0027] like Figure 1-Figure 2 and Figure 8 As shown, it also includes an anti-skid ring 12 and an anti-skid pad 13, both of which are made of rubber material. The anti-skid ring 12 is provided on the outer side of the middle part of the handle 11 through a rubber sleeve, and the anti-skid ring 12 is provided with symmetrical anti-skid teeth in a concave and convex shape, which increase the friction of the hand when the handle 11 is grasped. The bottom of the reagent box body 1 is provided with an anti-skid pad 13 through glue. The anti-skid pad 13 can prevent the bottom of the reagent box body 1 from being worn due to friction when it is placed, and the anti-skid pad 13 can be placed more stably on the platform of the work desk.

[0028] like Figure 2 As shown, it also includes a sealing ring 14, which is made of rubber material. The sealing ring 14 is provided at the bottom of the reagent box cover 2 by means of glue. When the reagent box cover 2 is closed on the reagent box body 1, the sealing ring 14 will contact the inner wall of the connection between the reagent box body 1 and the reagent box cover 2 to ensure the sealing inside the reagent box body 1.

[0029] When it is necessary to place the test tube 7 with the extracted sample in the reagent box body 1, first twist the lock ring of the knob lock 9 to unlock it, then hold the buckle 10 to remove it from the buckle of the knob lock 9, at this time, hold the handle 11 to rotate the reagent box cover 2 open through the hinge 8, and then manually place the test tube 7 with the extracted sample in the reagent tube tray 3, so that the bottom of the test tube 7 is squeezed and pushed to the top of the clamping plate 6, so that the clamping plate 6 moves inward synchronously along the slide groove in the reagent tube tray 3 under the driving force of the test tube 7, and in this process, the spring 5 will move inward with the clamping plate 6 and be squeezed by force, thereby deforming and shortening. When the test tube 7 is completely placed, the test tube 7 no longer squeezes the clamping plate 6, and the spring 5 is no longer subjected to force and is reset, deformed and elongated, and drives the clamping plate 6 to move outward synchronously, and the clamping plate 6 moves outward At the same time as the synchronous movement, the extension force of the spring 5 will clamp the outer side of the test tube 7, squeeze the bottom of the test tube 7 and push it to the top of the clamping plate 6, so that the clamping plate 6 moves inward along the slide groove in the reagent tube tray 3 under the driving force of the test tube 7. In this process, the spring 5 will be squeezed by the clamping plate 6 during movement and deformed and shortened. When the test tube 7 is placed, the test tube 7 no longer squeezes the clamping plate 6. The spring 5 is no longer subjected to force and is reset to deform and elongate, and drives the clamping plate 6 to move outward. When the clamping plate 6 moves outward, the extension force of the spring 5 will clamp the outer side of the test tube 7. When all the test tubes 7 with extracted samples are placed in the reagent box body 1, the reagent box cover 2 is closed, and the buckle 10 and the knob lock 9 are matched and locked, thereby completing the work of placing the test tube 7 with extracted samples in the reagent box body 1.
