Description

Technical Field

[0001] This utility model relates to the field of clenbuterol detection, specifically to a clenbuterol detection device. Background Technology

[0002] Lean meat powder is a common name for a class of β-agonist drugs, mainly including clenbuterol and ractopamine, which are illegally added to feed to promote livestock growth and increase lean meat percentage. Its core harm is that the lean meat powder residue in animal tissues can enter the human body through consumption, causing poisoning symptoms such as palpitations, muscle tremors, and dizziness. Long-term intake may also cause chronic damage to the cardiovascular system. When testing for clenbuterol, colloidal gold immunochromatographic test strips are typically used – the (clenbuterol) rapid test kit (colloidal gold). No complex instruments are required, only test strips and a matching small reader (or visual reading). Qualitative or semi-quantitative detection is achieved through antigen-antibody reaction, with results available within 10-30 minutes. It is low-cost and highly portable. When using a colloidal gold immunochromatographic test strip (clenbuterol) rapid test kit to detect clenbuterol in animal tissue, the prepared solution containing animal tissue is dripped into the sample well of the test device using a dropper. The reaction zone of the test device is then observed for the presence of clenbuterol. However, the sample well is small, and even slight hand tremors can cause the solution to easily deviate from the correct position during dripping. This results in insufficient sample entering the sample well, leading to an inadequate sample volume entering the reaction system. This can cause an excessively low antigen concentration on the test strip, potentially resulting in false negatives for samples that should be positive, leading to missed detection of clenbuterol residues and posing a food safety risk. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting clenbuterol, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a device for detecting clenbuterol is provided, comprising a detection stage, the surface of which is covered with a positioning platform, and a test kit is mounted on the positioning platform; an adjustable support mechanism is fixedly disposed on the side wall of the detection stage, and a drop-addressing positioning bucket is mounted at the end of the adjustable support mechanism, the bottom of which is positioned directly above the sample dispensing hole on the test kit; the adjustable support mechanism includes a fixed base fixedly connected to the detection stage, and a support arm is mounted on the top of the fixed base, while a stud is fixedly disposed on the top of the support arm.

[0005] Furthermore, a base plate is fixedly provided at the bottom of the positioning platform, and three sets of box positioning slots are equally spaced on the positioning platform. At the same time, test kits are snapped into the interior of each of the three sets of box positioning slots, and the distance between the three sets of test kits is consistent. An "L"-shaped retainer is fixedly provided at the end of each box positioning slot, and the test kit is positioned on the box positioning slot by the retainer.

[0006] Furthermore, a limiting seat is fixedly provided at the bottom of the base plate, and a limiting groove is opened on the surface of the detection table. The limiting groove is adapted to the size of the limiting seat, and the limiting seat is inserted into the inside of the limiting groove.

[0007] Furthermore, both the limiting groove and the limiting seat have dovetail-shaped cross sections, and end seats are fixedly installed at both ends of the detection platform. Both ends of the limiting groove are sealed by the end seats.

[0008] Furthermore, the adjustable support mechanism also includes a spring, a limiting plate, an adjusting seat, and a connecting seat. The connecting seat is fixed to the end of the adjusting seat, and a through hole is provided inside the connecting seat. The bottom of the drip positioning bucket is inserted into the through hole, and the top and bottom of the drip positioning bucket are both conical.

[0009] Furthermore, the adjusting seat has a through hole inside, and a stud passes through this through hole and is screwed in and fixed by a nut. A spring is also sleeved on the outside of the stud, and the spring is located between the adjusting seat and the support arm.

[0010] Furthermore, a limiting plate is fixedly provided on the side wall of the support arm, and the limiting plate is inserted into a limiting hole opened on the adjusting seat. Both the limiting plate and the limiting hole are rectangular.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution uses three sets of positioning slots to hold the test kit. The prepared solution for testing clenbuterol is accurately added to the sample well of the test kit through the dropping positioning funnel. The solution will not deviate from the sample well when dripping, and all the solution can enter the sample well, which improves the accuracy of the test results and avoids problems such as insufficient sample volume or contamination caused by solution deviation. 2. This solution eliminates the need for frequent disassembly and reassembly of reagent kits by using three sets of test kits alternately. This reduces equipment displacement and reagent kit loosening caused by repeated operation of the positioning stage, kit positioning slot, or test kits. Operators do not need to repeatedly prepare new test kits or adjust the positioning stage position between tests. They only need to complete the solution addition and lateral movement of the positioning stage according to a fixed procedure, simplifying the operation steps. There is no need to wait for the reaction to complete. Simply move the positioning stage laterally to move the test kit without solution to the bottom of the addition positioning hopper to start the next set of tests. This significantly reduces the test interval and is especially suitable for batch animal tissue clenbuterol testing scenarios, significantly improving overall testing efficiency.

[0014] Please see Figure 1-5 This utility model provides a detection device for clenbuterol, including a detection platform 1, the surface of which is covered with a positioning platform 4, and a detection kit 7 is installed on the positioning platform 4; an adjustable support mechanism 8 is fixedly installed on the side wall of the detection platform 1, and a drop positioning bucket 9 is installed at the end of the adjustable support mechanism 8, with the bottom of the drop positioning bucket 9 positioned directly above the sample dispensing hole on the detection kit 7; the adjustable support mechanism 8 includes a fixed base 80 fixedly connected to the detection platform 1, and a support arm 81 is installed on the top of the fixed base 80, while a stud 82 is fixedly installed on the top of the support arm 81.

[0015] Working principle: During use, three sets of box positioning slots 42 are equidistantly arranged on the positioning stage 4, and each of the three sets of box positioning slots 42 is fitted with a test kit 7. The prepared solution for detecting clenbuterol is accurately dripped into the sample dispensing hole of the test kit 7 through the dripping positioning funnel 9. The solution will not deviate from the sample dispensing hole when dripping, and all the solution can enter the sample dispensing hole, improving the accuracy of the test results of the test kit 7. During the reaction of the test kit 7, the positioning stage 4 can be moved laterally, and the test kit 7 that has not been dripped will be moved to the bottom of the dripping positioning funnel 9, so that the next set of tissue solutions can be used for clenbuterol detection. The three sets of test kits 7 are used alternately to improve the detection efficiency of different tissue samples. The dripping positioning funnel 9 needs to be replaced after each use. The replaced dripping positioning funnel 9 should be cleaned and tested to avoid affecting the next use.

[0016] In a preferred embodiment, a base plate 5 is fixedly provided at the bottom of the positioning platform 4, and three sets of box positioning slots 42 are equally spaced on the positioning platform 4. At the same time, test kits 7 are snapped into the interior of each of the three sets of box positioning slots 42, and the distance between the three sets of test kits 7 is consistent. An "L"-shaped card seat 41 is fixedly provided at the end of the box positioning slot 42, and the test kits 7 are positioned on the box positioning slot 42 by the card seat 41.

[0017] A limiting seat 6 is fixedly installed at the bottom of the base plate 5. A limiting groove 2 is opened on the surface of the testing table 1, and the size of the limiting groove 2 is adapted to the limiting seat 6. At the same time, the limiting seat 6 is inserted into the inside of the limiting groove 2.

[0018] Both the limiting groove 2 and the limiting seat 6 have dovetail-shaped cross sections. Both ends of the testing table 1 are fixedly provided with end seats 3, and both ends of the limiting groove 2 are sealed by the end seats 3.

[0019] like Figure 1-5As shown: The three sets of positioning slots 42 on the positioning stage 4, which are corresponding to the detection kits 7, can be used alternately. When one set of detection kits 7 is undergoing a solution reaction, there is no need to wait for the reaction to complete. Simply move the positioning stage 4 laterally to move the detection kit 7 without added solution to the bottom of the dropping positioning hopper 9 to start the next set of tests. This significantly reduces the detection interval, making it particularly suitable for batch animal tissue ractopamine testing scenarios and significantly improving overall detection efficiency. On the one hand, when the solution is added through the dropping positioning hopper 9, it can accurately enter the sample dispensing hole of the detection kit 7, avoiding insufficient sample volume or contamination caused by solution deviation. On the other hand, the alternating use of the three sets of detection kits 7 eliminates the need for frequent disassembly and assembly of the kits, reducing equipment displacement and kit loosening caused by repeated operation of the positioning stage 4, positioning slots 42, or detection kits 7, further reducing detection errors and ensuring safety. Results are accurate; in alternating use mode, operators do not need to repeatedly prepare new test kits 7 or adjust the position of the positioning stage 4 between tests. They only need to complete the solution addition and lateral movement of the positioning stage 4 according to the fixed procedure, simplifying the operation steps; at the same time, the three sets of positioning slots 42 are equidistantly set, which makes it easy for operators to quickly identify the position of the test kit 7, reduce operational errors, and improve the overall ease of operation; the alternating use of the three sets of test kits 7 can achieve seamless connection of reaction and detection processes, avoid long-term idleness or overuse of a single test kit, and ensure that each set of test kits 7 can play its role within the effective reaction cycle; at the same time, the utilization rate of equipment such as the positioning stage 4 and the dropping positioning bucket 9 is also improved, and the batch testing needs can be met without additional equipment investment, which indirectly reduces the waste of consumables and equipment resources while ensuring the detection effect; As a preferred embodiment, the adjustable support mechanism 8 also includes a spring 83, a limiting plate 84, an adjusting seat 85, and a connecting seat 86. The connecting seat 86 is fixed to the end of the adjusting seat 85, and a through hole is provided inside the connecting seat 86. The bottom of the drip positioning bucket 9 is inserted into the through hole, and the top and bottom of the drip positioning bucket 9 are both conical.

[0020] The adjusting seat 85 has a through hole inside, and the stud 82 passes through this through hole and is screwed in and fixed by a nut. A spring 83 is also sleeved on the outside of the stud 82, and the spring 83 is located between the adjusting seat 85 and the support arm 81.

[0021] A limiting plate 84 is fixedly installed on the side wall of the support arm 81, and the limiting plate 84 is inserted into the limiting hole opened on the adjusting seat 85. Both the limiting plate 84 and the limiting hole are rectangular.

[0022] The distance between the sample dispensing hole on the test kit 7 and the bottom surface of the dispensing positioning bucket 9 can be adjusted by the adjustable support mechanism 8. Specifically, the nut on the outside of the stud 82 is rotated, and the nut moves downward, which drives the adjusting seat 85 and the connecting seat 86 to move downward and compresses the spring 83. The height of the dispensing positioning bucket 9 can be adjusted by rotating the nut in the clockwise and counterclockwise directions. like Figure 1-5 As shown: The adjustable support mechanism 8 adjusts the distance between the sample dispensing hole on the test kit 7 and the bottom of the dispensing positioning funnel 9, accommodating test kits 7 with different thicknesses and sample dispensing hole heights. When replacing test kits 7 with different specifications, simply rotate the nut on the outside of the stud 82 to move the adjusting seat 85 and the connecting seat 86 up and down, thus adjusting the height of the dispensing positioning funnel 9 without replacing the entire set of equipment. This significantly improves the compatibility of the positioning stage 4 and the dispensing positioning funnel 9, reducing equipment replacement costs. The distance adjustment function can optimize the distance between the dispensing positioning funnel 9 and the sample dispensing hole based on solution characteristics such as viscosity, dripping speed, and the size of the sample dispensing hole on the test kit 7. For example, for solutions that easily adhere to the wall, the height of the dispensing positioning funnel 9 can be appropriately lowered to reduce splashing or deviation during solution dripping; for solutions that easily foam, the distance can be appropriately increased to prevent the solution from directly impacting the bottom of the sample dispensing hole and generating air bubbles. By precisely adjusting the distance, combined with the positioning function of the dispensing positioning funnel 9 itself, it is further ensured that the solution enters the sample dispensing hole in full and without deviation, guaranteeing the accuracy of the test results of the test kit 7. The adjustable support mechanism 8 can be adjusted simply by rotating the nut on the outside of the stud 82 clockwise or counterclockwise. No complicated tools or professional operation are required. Operators can fine-tune the spacing at any time according to the real-time detection. During the adjustment process, the spring 83 can play a buffering role to prevent the rapid movement of the adjusting seat 85 and the connecting seat 86 from causing the drip positioning bucket 9 to shake. This balances the convenience of operation and the stability of adjustment, and lowers the threshold for operation. Adjusting the spacing appropriately can prevent direct contact between the dispensing positioning funnel 9 and the test kit 7. If the spacing is too small, the dispensing positioning funnel 9 may compress the test kit 7 and cause it to deform. If the spacing is too large, the impact force when the solution drips may be too great and damage the edge of the sample dispensing hole. By controlling the spacing within a reasonable range through the adjustable support mechanism 8, the test kit 7 can be protected from external damage, and the dispensing positioning funnel 9 can also be prevented from being damaged by collision, thus indirectly extending the service life of the equipment and consumables.
