Description
Technical Field
[0001] This utility model relates to the field of detection devices, specifically a rapid detection device for multiple pesticide residues. Background Technology
[0002] The development of agricultural industrialization has made agricultural production increasingly reliant on exogenous substances such as pesticides, antibiotics, and hormones. The amount of pesticides used in agricultural products in my country remains high. The unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer safety. In severe cases, it can cause illness, abnormal development, or even direct poisoning and death in consumers.
[0003] The rapid pesticide residue detector is a specialized instrument developed based on my country's national conditions and market needs. It can be widely used in product quality supervision and inspection, industrial and commercial administration, vegetable production bases, supermarkets, pesticide residue monitoring systems and other departments to detect pesticide residues in vegetables and fruits. Nowadays, the most common rapid pesticide residue detection device usually involves the user preparing the sample and placing it into a sampling tube, adding different solvents to the test reagent multiple times, and finally placing the reagent into the detection device to test the sample.
[0004] However, existing rapid pesticide residue detection devices often use a setup where a single sampling tube is placed in a slot. When using such devices to test samples, the solvent preparation process is cumbersome, requiring multiple operations on the sampling tube. Users can only pick up or place one sampling tube at a time, which is inconvenient, increases the workload, and reduces detection efficiency. Therefore, there is an urgent need to improve existing rapid pesticide residue detection devices. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a rapid detection device for multiple pesticide residues to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid detection device for multiple pesticide residues, comprising a device body, wherein the device body is provided with a detection area and a detection hole, and a receiving plate is provided on the detection area for receiving multiple sets of sampling tubes;
[0007] The receiving plate has a first sliding rod and a second sliding rod that are offset from each other, and the outer walls of the first sliding rod and the second sliding rod are respectively equipped with a first clamping block and a second clamping block corresponding to the sampling tube, which are used to clamp and fix the sampling tube installed on the receiving plate.
[0008] A handle is rotatably mounted on the top of the receiving plate, and a transmission mechanism corresponding to the handle, the first slide rod, and the second slide rod is provided inside the receiving plate. The transmission mechanism works in conjunction with the handle to ensure that when the handle is in the open state, the first clamping block and the second clamping block are in the state of clamping the sampling tube.
[0009] By adopting the above technical solution, when the user lifts the receiving plate with the handle, multiple sampling tubes can also be lifted together, which solves the problem of users having to take out the sampling tubes separately when preparing solvents, reduces the workload of users, and improves the efficiency of testing.
[0010] Furthermore, the receiving plate has multiple sets of tube holes corresponding to the detection holes, and the diameter of the tube holes is larger than the diameter of the sampling tube body, but smaller than the diameter of the top of the sampling tube.
[0011] By adopting the above technical solution, it is ensured that the sampling tube is smoothly inserted into the tube hole, and the top locking mechanism ensures that the sampling tube will not fall from the bottom when it is inside the tube hole.
[0012] Furthermore, the first slide bar and the second slide bar are respectively disposed on both sides of the pipe hole and are offset from the opening position of the pipe hole.
[0013] By adopting the above technical solution, interference between the first and second sliding rods and the sampling tube inside the borehole can be avoided during their movement.
[0014] Furthermore, multiple sets of first clamping blocks and second clamping blocks are respectively provided on the outer walls adjacent to the first and second sliding rods. The receiving plate has a sliding groove corresponding to the first and second clamping blocks, and the sliding groove communicates with the pipe hole to ensure that the first and second clamping blocks can smoothly clamp the side wall of the sampling tube.
[0015] By adopting the above technical solution, and by setting multiple sets of first clamping blocks and second clamping blocks, each set of corresponding first clamping blocks and second clamping blocks can clamp each sampling tube, and the first clamping blocks and second clamping blocks respectively can clamp the sampling tube more securely from both sides.
[0016] Furthermore, the outer walls of both the first clamping block and the second clamping block have the same arc surface design as the outer wall of the sampling tube, and the contact positions between the first clamping block and the second clamping block and the sampling tube are both made of rubber material.
[0017] By adopting the above technical solution, and by utilizing the frictional properties and elasticity of rubber, the first clamping block and the second clamping block can fit more tightly when clamping the sampling tube, thereby increasing the stability of the clamping.
[0018] Furthermore, the transmission mechanism includes toothed plates installed at the ends of the first slide rod and the second slide rod, and the toothed plates are respectively located at the ends of the first slide rod and the second slide rod with the largest distance. A gear corresponding to the toothed plate is rotatably installed inside the receiving plate.
[0019] By adopting the above technical solution, the rotational motion of the gear is converted into the linear motion of the gear plate through the meshing connection between the gear plate and the gear, thereby driving the first slide bar and the second slide bar to move.
[0020] Furthermore, two sets of handles are rotatably mounted on the top of the receiving plate. The two sets of handles correspond to the first slide rod and the second slide rod, respectively. A transmission rod that is fixedly connected to the gear is fixedly mounted on the outer wall of the handle, and the two sets of handles rotate in opposite directions.
[0021] By adopting the above technical solution, the first slide bar and the second slide bar can move in opposite directions by rotating the two sets of handles in opposite directions, thereby driving the first clamping block and the second clamping block to clamp the sampling tube.
[0022] In summary, the present invention has the following main advantages:
[0023] This invention, by incorporating a receiving plate and a handle, allows users to lift the receiving plate directly during multiple solution preparation processes, simultaneously lifting multiple sampling tubes. This eliminates the inconvenience of individually removing sampling tubes during solvent preparation, reducing the user's workload and improving testing efficiency. The inclusion of clamping blocks and a transmission mechanism ensures that when lifting the receiving plate and sampling tubes, rotating the handle activates the transmission rod, which in turn moves the gears and toothed plate. This movement of the sliding rod connected to the toothed plate and clamping blocks allows the clamping blocks to securely hold the sampling tubes, maintaining stability and preventing spillage of the test reagents due to shaking.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0030] The embodiments of this utility model will be described below based on its overall structure.
[0031] A rapid detection device for multiple pesticide residues, such as Figure 1 - Figure 4 As shown, it includes the main body of the device 1.
[0032] Specifically, the main body 1 of the device is provided with a detection area 2 and a detection hole 21, and the detection area 2 is provided with a receiving plate 4 for receiving multiple sets of sampling tubes 3. When the user lifts the receiving plate 4 with the handle 9, the multiple sets of sampling tubes 3 can also be lifted together, which solves the trouble of the user having to take out the sampling tubes 3 separately when preparing solvent, reduces the workload of the user, and improves the efficiency of the detection work.
[0033] The receiving plate 4 has a first sliding rod 6 and a second sliding rod 61 that are slidably installed inside it. The staggered design can avoid the first sliding rod 6 and the second sliding rod 61 from interfering with each other during the sliding process. The outer walls of the first sliding rod 6 and the second sliding rod 61 are respectively equipped with a first clamping block 7 and a second clamping block 71 corresponding to the sampling tube 3. This allows the first sliding rod 6 and the second sliding rod 61 to slide inside the receiving plate 4, thereby driving the first clamping block 7 and the second clamping block 71 installed on them to move, which is used to clamp and fix the sampling tube 3 installed on the receiving plate 4.
[0034] A handle 9 is rotatably mounted on the top of the receiving plate 4, and a transmission mechanism corresponding to the handle 9, the first slide rod 6, and the second slide rod 61 is provided inside the receiving plate 4. The transmission mechanism works in conjunction with the handle 9. The rotational motion of the handle 9 can be converted into the linear motion of the first slide rod 6 and the second slide rod 61 through the transmission mechanism, so as to ensure that when the handle 9 is in the open state, the first clamping block 7 and the second clamping block 71 are in the state of clamping the sampling tube 3.
[0035] Please see Figure 1 - Figure 4The receiving plate 4 has multiple sets of tube holes 5 corresponding to the detection hole 21. The diameter of the tube hole 5 is larger than the diameter of the tube body of the sampling tube 3, so as to ensure that the sampling tube 3 can be smoothly inserted into the tube hole 5, but smaller than the diameter of the top of the sampling tube 3. The top locking position ensures that the sampling tube 3 will not fall from the bottom when it is in the tube hole 5.
[0036] Please see Figure 1 - Figure 4 The first slide rod 6 and the second slide rod 61 are respectively set on both sides of the tube hole 5 and are offset from the opening position of the tube hole 5 to avoid interference between the first slide rod 6 and the second slide rod 61 and the sampling tube 3 inside the tube hole 5 when they move.
[0037] Please see Figure 1 - Figure 4 Multiple sets of first clamping blocks 7 and second clamping blocks 71 are respectively provided on the outer walls adjacent to the first sliding rod 6 and the second sliding rod 61. By providing multiple sets of first clamping blocks 7 and second clamping blocks 71, each set of corresponding first clamping blocks 7 and second clamping blocks 71 can clamp each sampling tube 3. The first clamping blocks 7 and second clamping blocks 71 respectively can clamp the sampling tube 3 more securely from both sides. The receiving plate 4 has a sliding groove corresponding to the first clamping blocks 7 and second clamping blocks 71, and the sliding groove communicates with the tube hole 5 to ensure that the first clamping blocks 7 and second clamping blocks 71 can smoothly clamp the side wall of the sampling tube 3.
[0038] Please see Figure 1 - Figure 4 The outer walls of the first clamping block 7 and the second clamping block 71 are both designed with the same arc surface as the outer wall of the sampling tube 3. The same arc surface design allows the outer walls of the first clamping block 7 and the second clamping block 71 to fit more closely when clamping the sampling tube 3. Furthermore, the contact points between the first clamping block 7 and the second clamping block 71 and the sampling tube 3 are made of rubber. By utilizing the frictional properties and elasticity of rubber, the first clamping block 7 and the second clamping block 71 can fit more tightly when clamping the sampling tube 3, thereby increasing the stability of the clamping.
[0039] Please see Figure 1 - Figure 4 The transmission mechanism includes a toothed plate 8 installed at the ends of the first slide rod 6 and the second slide rod 61. The toothed plate 8 is respectively located at the ends of the first slide rod 6 and the second slide rod 61 with the largest distance. A gear 92 corresponding to the toothed plate 8 is rotatably installed in the receiving plate 4. Through the meshing connection between the toothed plate 8 and the gear 92, the rotational motion of the gear 92 is converted into the linear motion of the toothed plate 8, thereby driving the first slide rod 6 and the second slide rod 61 to move.
[0040] Please see Figure 1 - Figure 4Two sets of handles 9 are rotatably installed on the top of the receiving plate 4. The two sets of handles 9 correspond to the first slide rod 6 and the second slide rod 61 respectively. A transmission rod 91 fixedly connected to the gear 92 is fixedly installed on the outer wall of the handles 9. The two sets of handles 9 rotate in opposite directions. The opposite rotation directions of the two sets of handles 9 enable the first slide rod 6 and the second slide rod 61 to move in opposite directions, thereby driving the first clamping block 7 and the second clamping block 71 to clamp the sampling tube 3.
[0041] The working principle of this utility model is as follows: When using this detection device, the user first opens the cover 10, inserts the sampling tube 3 containing the reagent through the tube hole 5 into the detection hole 21, and waits for operation. When it is necessary to add solution to the reagent in the sampling tube 3, the user can rotate and lift the handle 9 from the groove at the bottom, thereby removing the receiving plate 4 and all sampling tubes 3 at the same time. This solves the problem of users having to remove the sampling tubes 3 individually and multiple times to prepare the solvent, reducing the workload of the user and improving the efficiency of the detection work. During the process, by rotating the handle 9, multiple sets of gears 92 installed on the transmission rod 91 are rotated, converting the rotational motion of the gears 92 into the linear motion of the toothed plate 8, causing the toothed plate 8 connected to the gears 92 to move to the other end. At the same time, multiple sets of first clamping blocks 7 move with the first sliding rod 6, while multiple sets of second clamping blocks 71 move with the second sliding rod 61 in the opposite direction, thereby achieving the function of clamping the sampling tube 3. This allows the user to maintain the stability of the sampling tube 3 during the process of lifting the receiving plate 4 and the sampling tube 3, and avoids the sampling tube 3 shaking and causing the test reagent to leak.
[0042] After the user has prepared the reagent in the sampling tube 3, lift the handle 9 and align the bottom of the sampling tube 3 with the detection hole 21 so that the tube body of the sampling tube 3 can smoothly enter the detection hole 21. After placing the receiving plate 4, rotate the handle 9 to reset it, so as to prevent the handle 9 from standing up and obstructing the closing of the cover 10. During this process, the rotation of the handle 9 causes the multiple sets of gears 92 installed on the transmission rod 91 to rotate, so that the gears 92 drive the tooth plate 8 to reset. At the same time, multiple sets of first clamping blocks 7 move with the first slide rod 6, while multiple sets of second clamping blocks 71 move in the opposite direction with the second slide rod 61, thereby releasing the clamping and fixing of the sampling tube 3. After the user has placed the sampling tube 3 properly, close the cover 10 to cover the opening of the sampling tube 3 and prevent foreign objects from falling into the reagent, which could cause incorrect test results.
