Description

Technical Field

[0001] This invention relates to the field of drug detection equipment, and more particularly to a handheld drug detection device. Background Technology

[0002] A drug detection device is a device used to detect drugs. It mainly identifies the presence of potential drug substances by performing chemical analysis or physical testing on samples. A handheld device refers to a device or tool that can be carried by hand. The advantages of handheld drug detection devices are portability, ease of operation, fast detection speed, and strong real-time performance. They are widely used in police enforcement, security checks, prison management, event security, and other fields to help law enforcement officers quickly screen and identify potential drug threats.

[0003] Currently, when using handheld drug detection devices, the first step is to place the person's identification card at the bottom of the device. The device then reads the person's information and inserts a prepared test kit into a slot. The internal probe then detects the substances on the surface of the test kit. However, the probe typically detects the substances on the test kit surface using light, and is usually positioned relatively far from the slot. This prevents the probe from making proper contact with the test kit, making it difficult to detect substances on the surface and reducing detection sensitivity and efficiency.

[0004] Therefore, it is necessary to provide a new handheld drug detection device to solve the above-mentioned technical problems. Summary of the Invention

[0018] Compared with related technologies, the handheld drug detection device provided by this invention has the following advantages:

[0019] 1. This invention, through the arrangement of a driving component, a movable plate, a connecting plate, a first clamping plate, a second clamping plate, and a second spring, allows adjustment of the distance between the reagent plate and the probe head. This enables the probe head to better adhere to the surface of the reagent plate, increasing the interaction between the target substance in the sample and the reagent, making the detected substance easier to detect. It also enables reliable detection of target substances at lower concentrations, improving detection sensitivity and efficiency. Simultaneously, the movable plate moves while the first and second clamping plates limit the reagent plate, preventing it from shaking due to external vibrations or interference during the use of the drug detection instrument. This increases the stability of the reagent plate during detection and improves the accuracy of the drug detection data.

[0020] 2. As the connecting plate moves along the slide rail at the bottom of the drug detection device, it will drive the rebound component to move to one side of the drug detection device, thereby moving one end of the identity card inside the rebound component out of the bottom of the drug detection device, so that the user can directly pull out the identity card for convenient use.

[0036] In the specific implementation process, such as Figures 1-12 As shown, a handheld drug detection device includes a drug detection device body 1 and a reagent plate 2. The drug detection device body 1 is provided with a probe 3 and an adjustment device for adjusting the distance between the probe 3 and the reagent plate 2. The bottom of the probe 3 is fixedly connected to the top of the adjustment device.

[0037] The adjustment device includes a drive assembly, a movable plate 5, a limiting member, a connecting plate 7, a mounting plate 18, a blocking assembly, a first clamping plate 20, a fixing post 29, and a rebound assembly 10. One end of the drive assembly penetrates the bottom of the drug detection instrument body 1 and is movably connected to the drug detection instrument body 1. One side of the drive assembly and one end of the movable plate 5 are both inclined, and one side of the drive assembly is in contact with one end of the movable plate 5. The top of the movable plate 5 is fixedly connected to the bottom of the detector head 3, and one side of the movable plate 5 is fixedly connected to one end of the limiting member. The end of the limiting member away from the movable plate 5 is fixedly connected to one side of the inner wall of the drug detection instrument. The end of the movable plate 5 away from the drive component is provided with a push groove that matches the connecting plate 7. One side of the connecting plate 7 and one side of the inner wall of the push groove are both inclined. One side of the connecting plate 7 is in contact with one side of the inner wall of the push groove. The connecting plate 7 can move inside the push groove. The bottom of the drug detection instrument body 1 is provided with a slide rail that matches the bottom end of the connecting plate 7. The bottom end of the connecting plate 7 passes through the slide rail opened at the bottom of the drug detection instrument body 1 and is fixedly connected to the top of the rebound component 10. The connecting plate 7 can slide inside the slide rail.

[0038] One side of the connecting plate 7 is fixedly connected to one side of the mounting plate 18, and the bottom of the mounting plate 18 is attached to the bottom of the inner wall of the drug detection instrument body 1. The mounting plate 18 is movably connected to the drug detection instrument body 1. A second clamping plate 25 is fixedly provided on the top of the mounting plate 18. The two ends of the blocking component are fixedly connected to one end of the mounting plate 18 and the top of the inner wall of the drug detection instrument body 1, respectively. One side of the first clamping plate 20 is attached to the blocking component. The first clamping plate 20 is movably connected to the blocking component. An L-shaped slot is opened on the side of the first clamping plate 20 near the blocking component. A second spring 23 is fixedly provided on the side of the first clamping plate 20 near the blocking component. The end of the second spring 23 away from the first clamping plate 20 is fixedly connected to one side of the blocking component.

[0039] The bottom end of the fixed column 29 is fixedly connected to the top of the mounting plate 18. A third return spring 28 is movably sleeved on the surface of the fixed column 29. One end of the third return spring 28 is fixedly connected to the top of the mounting plate 18. A blocking block 30 is fixedly provided at the end of the third return spring 28 away from the mounting plate 18. The top two ends of the blocking block 30 and the bottom two ends of the first clamping plate 20 are inclined. The top of the blocking block 30 is in contact with the bottom of the first clamping plate 20. The top of the blocking block 30 is movably connected to the bottom of the first clamping plate 20. Multiple limiting blocks 26 for limiting the reagent plate 2 are respectively provided on the adjacent side of the first clamping plate 20 and the second clamping plate 25. Press the drive component inside the drug detection instrument. One side and one end of the movable plate 5 are both inclined, and one side of the drive assembly is in contact with one end of the movable plate 5. Therefore, when the drive assembly moves into the body 1 of the drug detection instrument, it will push the movable plate 5 towards the reagent plate 2, causing the movable plate 5 and the detector head 3 on top of the movable plate 5 to move. This adjusts the distance between the detector head 3 and the reagent plate 2, allowing the detector head 3 to better contact the surface of the reagent plate 2, increasing the interaction between the target substance in the sample and the reagent, making the detected substance easier to detect. Simultaneously with the movement of the movable plate 5, because one side of the connecting plate 7 and one side of the inner wall of the pushing groove are both inclined, and one side of the connecting plate 7 is in contact with one side of the inner wall of the pushing groove, When the movable plate 5 moves, the connecting plate 7 slides inside the slide rail at the bottom of the drug detection instrument body 1, thereby causing the connecting plate 7 to move the mounting plate 18. When the mounting plate 18 moves, because one side of the connecting plate 7 and one side of the inner wall of the push groove at one end of the movable plate 5 are both inclined and fit together, when the movable plate 5 moves towards the reagent plate 2, it pushes the connecting plate 7 to move along the slide rail at the bottom of the drug detection instrument body 1. At the same time, the moving connecting plate 7 drives the mounting plate 18 to move. When the mounting plate 18 moves inside the drug detection instrument body 1, it drives the second clamping plate 25 to move towards the reagent plate 2. At the same time, because the top two ends of the blocking block 30 and the bottom of the first clamping plate 20... Both ends of the part are inclined, and one side of the first clamping plate 20 is in contact with one side of the baffle 21. Therefore, when the blocking block 30 slides, it will move towards the mounting plate 18 and squeeze the third return spring 28. When the blocking block 30 slides to the other surface of the first clamping plate 20, the third return spring 28 will drive the blocking block 30 to return to its original position. Since the first clamping plate 20 is no longer blocked by the blocking block 30, it will move towards the reagent plate 2 through the elastic force of the second spring 23. The reagent plate 2 is limited by the first clamping plate 20 and the second clamping plate 25, and the limiting block 26 set on the adjacent side of the first clamping plate 20 and the second clamping plate 25 makes the reagent plate 2 more stable.

[0040] The driving assembly includes a pressing plate 4, a first reset spring 8, and a locking member 9. The bottom of the drug detection device body 1 has a sliding groove that matches one end of the locking member 9. One end of the locking member 9 is fixedly connected to one side of the inner wall of the sliding groove. The pressing plate 4 has multiple locking slots 11 on one side that match one end of the locking member 9. The end of the locking member 9 away from the sliding groove is located inside one of the locking slots 11 on one side of the pressing plate 4, and this end can slide inside the locking slots 11 on one side of the pressing plate 4. The top of the pressing plate 4 penetrates the bottom of the drug detection device body 1, and the pressing plate 4 is movably connected to the drug detection device body 1. A pressing device is fixedly provided on the top of the pressing plate 4. The pressure block 12 has its top fixedly connected to one end of the first return spring 8. The end of the first return spring 8 away from the top of the pressure block 12 is fixedly connected to the top of the inner wall of the drug detection instrument body 1. One side of the pressure block 12 and the end of the movable plate 5 near the pressure block 12 are both inclined, and one side of the pressure block 12 is in contact with one end of the movable plate 5. The one side of the pressure block 12 is movably connected to one end of the movable plate 5. The locking component 9 includes a first spring 15 and a locking plate 16. One end of the first spring 15 is fixedly connected to one side of the inner wall of the sliding groove opened at the bottom of the drug detection instrument body 1, and the other end of the first spring 15 is fixedly connected to one end of the locking plate 16. The end of the locking plate 16 away from the first spring 15 is located inside the slot 11 opened on one side of the pressing plate 4, and the end of the locking plate 16 away from the first spring 15 can slide inside the slot 11 opened on one side of the pressing plate 4. The bottom of the end of the locking plate 16 located inside the slot 11 is inclined. A pull rod 17 is fixedly connected to the bottom of the locking plate 16. Pressing the pressing plate 4 into the body 1 of the drug detection device causes the pressing plate 4 to move into the body 1 of the drug detection device. When the pressing plate 4 moves, one end of the locking plate 16 slides inside the slot 11 opened on one side of the pressing plate 4 and squeezes the first spring 15. When one end of the locking plate 16 slides out of the pressing plate 4, the first spring 15 is squeezed. When the plate 4 moves into the slot 11 on one side, one end of the locking plate 16 will slide along the side of the pressing plate 4 until one end of the locking plate 16 slides to the other slot 11 on the side of the pressing plate 4. Then, the elastic force of the first spring 15 will cause one end of the locking plate 16 to enter the slot 11. At the same time, when the pressing plate 4 moves into the body 1 of the drug detection instrument, it will drive the squeezing block 12 to move and squeeze the first reset spring 8. Because one side of the squeezing block 12 is inclined and fits against one end of the movable plate 5, when the squeezing block 12 moves towards the first reset spring 8, it will push the movable plate 5 towards the reagent plate 2.

[0041] The limiting component includes a limiting plate 6 and a second return spring 14. A limiting groove 13 matching one end of the limiting plate 6 is provided on one side of the movable plate 5.

One side of the baffle 21 is in contact with the side of the first clamping plate 20 near the fixed plate 19. The baffle 21 is movably connected to the first clamping plate 20. The top of the baffle 21 is in contact with the drug detection instrument body. The top of the inner wall of the body 1 is fixedly connected. One end of the movable column 22 passes through one side of the drug detection instrument body 1, both sides of the fixed plate 19 and both sides of the baffle 21 and extends into the L-shaped slot of the first clamping plate 20. The movable column 22 is movably connected to the drug detection instrument body 1, the fixed plate 19 and the baffle 21 respectively. The end of the movable column 22 near the first clamping plate 20 is L-shaped. The end of the movable column 22 away from the first clamping plate 20 is fixedly provided with a pull plate 27. When the squeezing block 12 pushes the movable plate 5, the movable plate 5 is limited by the limiting plate 6 inside the limiting groove 13 on one side of the movable plate 5, so that the movable plate 5 will not move towards the first return spring 8 with the squeezing block 12. When the movable plate 5 moves, it will squeeze the second return spring 14. The baffle 21 limits the first clamping plate 20, so that when the top of the blocking block 30 moves towards the bottom of the first clamping plate 20, it will not drive the first clamping plate 20 to move towards the fixed plate 19.

The top of the drug detection device body 1 is provided with a protective component 39 for shielding the placement slot. The protective component 39 includes a protective plate 40, a support rod 42, and two connecting posts 41. The bottom of the support rod 42 is fixedly connected to the top of the drug detection device body 1, and one end of each of the two connecting posts 41 is fixedly connected to one side of the support rod 42. The protective plate 40 has two through holes on both sides, and the two connecting posts 41 pass through the two through holes of the protective plate 40 respectively, and the connecting posts 41 are movably connected to the protective plate 40. The top of the protective plate 40 is provided with a groove. The groove is provided with multiple protrusions 24 to increase friction. One side of the protective plate 40 is attracted to the magnet on the side of the support rod 42 near the two connecting columns 41. Pressing the groove on the top of the protective plate 40 increases the friction between the protective plate 40 and the support rod 42 through the multiple protrusions 24 inside the groove, making it easier for the user to push the protective plate 40 towards the support rod 42. This causes the magnet on the side of the protective plate 40 adjacent to the support rod 42 to attract the protective plate 40. At the same time, the bottom of the protective plate 40 is separated from the placement slot on the top of the drug detection instrument body 1. One end of the reagent plate 2 is placed inside the placement slot on the top of the drug detection instrument body 1, and the end of the reagent plate 2 inside the placement slot contacts the top of the mounting plate 18.

[0044] The working principle provided by this invention is as follows: One end of the identity information card 37 is inserted into the engagement groove opened on one side of the limiting rod 35. The protective soft pads 38 set at the top and bottom of the inner wall of the engagement groove reduce the wear of the identity information card 37 and limit the identity information card 37, so that the drug detection instrument body 1 can read the identity information card 37. After reading the identity information, the groove opened at the top of the protective plate 40 is pressed. The multiple protrusions 24 set inside the groove increase the friction between the protective plate 40 and the protective plate 40, making it easier for the user to push the protective plate 40 towards the support rod 42. The magnets on the side of the protective plate 40 adjacent to the support rod 42 attract the protective plate 40. At the same time, the bottom of the protective plate 40 is separated from the placement groove opened at the top of the drug detection instrument body 1. One end of the reagent plate 2 is placed inside the placement groove opened at the top of the drug detection instrument body 1, and the end of the reagent plate 2 inside the placement groove contacts the top of the mounting plate 18.

[0045] Pressing the pressing plate 4 into the body 1 of the drug detection device causes it to move inward. As the pressing plate 4 moves, one end of the locking plate 16 slides within the slot 11 on one side of the pressing plate 4, squeezing the first spring 15. When one end of the locking plate 16 slides out of the slot 11, it slides along the side of the pressing plate 4 until it reaches another slot 11. At this point, the force of the first spring 15 causes one end of the locking plate 16 to re-enter the slot 11. Simultaneously, as the pressing plate 4 moves inward, it moves the squeezing block 12, squeezing the first reset spring 8. Since one side of the extrusion block 12 is inclined and fits against one end of the movable plate 5, when the extrusion block 12 moves toward the first reset spring 8, it will push the movable plate 5 toward the reagent plate 2. At the same time as the extrusion block 12 pushes the movable plate 5, the movable plate 5 is limited by the limiting plate 6 inside the limiting groove 13 opened on one side of the movable plate 5, so that the movable plate 5 will not move toward the first reset spring 8 with the extrusion block 12. When the movable plate 5 moves, it will squeeze the second reset spring 14. The movement of the movable plate 5 will drive the top probe 3 to move toward the reagent plate 2, thereby adjusting the distance between the reagent plate 2 and the probe 3, so that the probe 3 can better fit with the surface of the reagent plate 2.

[0046] Because one side of the connecting plate 7 and one side of the inner wall of the push groove at one end of the movable plate 5 are both inclined and fit together, when the movable plate 5 moves towards the reagent plate 2, it will push the connecting plate 7 to move along the slide rail at the bottom of the drug detection instrument body 1. Simultaneously, the moving connecting plate 7 will drive the mounting plate 18 to move. When the mounting plate 18 moves inside the drug detection instrument body 1, it will drive the second clamping plate 25 to move towards the reagent plate 2. At the same time, because both ends of the top of the blocking block 30 and both ends of the bottom of the first clamping plate 20 are inclined, and one side of the first clamping plate 20 fits against one side of the baffle 21, When the blocking block 30 slides, it will move towards the mounting plate 18 and squeeze the third return spring 28. When the blocking block 30 slides to the other surface of the first clamping plate 20, the third return spring 28 will cause the blocking block 30 to reset. Since the first clamping plate 20 is no longer blocked by the blocking block 30, the second spring 23 will cause the first clamping plate 20 to move towards the reagent plate 2. The first clamping plate 20 and the second clamping plate 25 will limit the reagent plate 2, and the limiting block 26 set on the adjacent side of the first clamping plate 20 and the second clamping plate 25 will make the reagent plate 2 more stable.

[0047] While the connecting plate 7 moves the mounting plate 18, it also moves the top plate 34. When the top plate 34 moves, it moves the two support rods 42. The two support rods 42 move the bottom plate 33 and the limiting rod 35, and stretch the two third springs 32. When the limiting rod 35 moves, it moves the identity information card 37 to one side of the drug detection device body 1, so that one end of the identity information card 37 moves out of the bottom of the drug detection device body 1, so that the user can directly pull out the identity information card 37 for convenient use.

[0048] When the reagent plate 2 is tested, pull the lever 17. The lever 17 moves the locking plate 16 and squeezes the first spring 15. When one end of the locking plate 16 moves out of the slot 11, the spring force of the first return spring 8 drives the squeezing block 12 and the pressing plate 4 to reset. When the squeezing block 12 resets, the rebound force of the second return spring 14 resets the movable plate 5. At the same time, the limiting rod 35 will reset due to the contraction of the two third springs 32. When the limiting rod 35 resets, it will... The top plate 34 drives the connecting plate 7 and the mounting plate 18 to reset. When the mounting plate 18 resets, it drives the second clamping plate 25 to move, so that the reagent plate 2 is no longer fixed by the first clamping plate 20 and the second clamping plate 25. The reagent plate 2 is then removed from the inside of the drug detection instrument body 1. Pulling the pull plate 27 causes the pull plate 27 to drive the movable column 22 to move. Because one end of the movable column 22 is fixed with an L-shaped locking block, and the L-shaped locking block is located in the L-shaped slot opened on the surface of the first clamping plate 20, the movable column 22 can move. When column 22 moves, it will drive the first clamping plate 20 to move as well, so that the bottom of the first clamping plate 20 contacts the top of the blocking block 30 and moves the blocking block 30 toward the mounting plate 18. When the blocking block 30 moves toward the mounting plate 18, it will compress the third return spring 28. When the bottom of the first clamping plate 20 is no longer in contact with the top of the blocking block 30, the blocking block 30 will be reset by the rebound force of the third return spring 28. When one side of the first clamping plate 20 contacts the other side of the baffle 21, the tension is released. Plate 27 causes the second spring 23 to rebound. When the second spring 23 rebounds, it will drive the first clamping plate 20 to move towards the blocking block 30. The blocking block 30 limits the first clamping plate 20. The protective plate 40 is pushed towards the placement slot, so that the protective plate 40 is separated from the support rod 42. The protective plate 40 protects the placement slot and prevents dust or other microparticles from entering the placement slot when the drug detection instrument body 1 is not in use, so as to affect the accuracy of the drug detection instrument body 1 in the next detection.
