Description

Technical Field

[0001] This utility model relates to the field of chemical reagent and auxiliary agent sampling technology, and more specifically, it relates to a chemical reagent and auxiliary agent sampler. Background Technology

[0002] In the current field of chemical reagent analysis and research, chemical reagent and auxiliary samplers are commonly used laboratory tools, but they suffer from various technical defects and application limitations. A serious technical bottleneck in traditional sampler design is the inability to effectively fix the piston connecting rod. This defect leads to a series of serious problems in practical applications, especially in the sample storage and transportation process after sampling. Because the connecting rod is exposed and lacks a fixing and protection mechanism, it is easily pushed by accidental touches by operators or slight collisions in the laboratory environment. Once the connecting rod moves under force, it will exert pressure on the internal reagents through the piston, causing precious chemical reagents or auxiliary agents to be accidentally squeezed out. This not only causes sample loss and waste, but may also cause potential chemical pollution and safety hazards to the surrounding environment and personnel, seriously affecting the accuracy of experimental data and the standardization of laboratory work.

[0003] To address the aforementioned issues, some equipment manufacturers in the industry have attempted to improve sampler designs by adding clamping and fixing structures, hoping to achieve temporary fixation of the connecting rod through mechanical clamping. However, these improved designs still have fundamental flaws: their fixing mechanisms are too simplistic and lack multiple safety mechanisms. In actual laboratory environments, chemical experiments are often accompanied by vibrations and collisions of varying intensities, such as centrifuge operation, fume hood opening and closing, and slight vibrations of the lab bench. Under these external forces, the simple clamping structure is prone to loosening or displacement, leading to a gradual weakening or even complete failure of the clamping force on the connecting rod. More seriously, this failure often occurs unintentionally. By the time the operator realizes that the fixing structure has loosened, it is often too late. Then, during continuous shaking, the chemical reagents are pushed out, causing irreversible loss and contamination, greatly increasing experimental risks and error rates, and severely restricting the reliability and practical value of chemical reagent and auxiliary samplers in precision experiments.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a chemical reagent and auxiliary sampler, which has the following beneficial effects:

[0017] 1. The control device, through the ingenious cooperation of a moving plate, a fixed sleeve, a control sleeve, a control block, a control sleeve, a control groove, a moving groove, a moving block, and a push block, forms a complete transmission mechanism, realizing precise control and fixation of the connecting rod. When the operator rotates the control sleeve, the moving plate drives the moving block to slide along a spiral path in the moving groove, thereby driving the control sleeve to move, so that the control groove drives the control block and the push block to move precisely. The connecting rod is clamped and fixed by the push spring and the push plate. This multi-stage linkage design solves the problem of unstable fixing of the connecting rod in traditional samplers, and to a certain extent prevents reagent leakage caused by accidental contact that causes the connecting rod to move, thus improving the safety during storage and transportation to a certain extent.

[0018] 2. The locking mechanism consists of a locking sleeve, locking block, locking spring, locking rod, locking hole, locking plate, and cylindrical block, forming a double-safety locking system. This mechanism guides the precise movement trajectory of the locking block and locking wheel through the fitting of the locking rail and locking groove. The locking wheel's engagement design between the two cylindrical blocks provides robust mechanical support for the entire mechanism. The cooperation between the locking rod and the locking hole, along with the elasticity of the locking spring, forms an outer layer of locking protection. This multi-layered protection mechanism significantly improves the sampler's shock resistance in complex experimental environments. Even under conditions such as centrifuge operation, fume hood door opening and closing, or laboratory bench vibration, the locking system remains stable, completely solving the defects of traditional clamping structures that are prone to loosening and displacement. It prevents reagent leakage caused by accidental movement of the connecting rod, greatly enhancing the reliability and practical value of the chemical reagent and auxiliary sampler in precision experiments.

[0028] Please see Figures 1-5 A chemical reagent and auxiliary sampler includes a buffer tube 1, a sampling tube 2 connected to one end of the buffer tube 1, and a control device connected to the other end of the buffer tube 1. The control device includes a moving plate 3, a fixed sleeve 4, a control sleeve 5, a control block 6, a control sleeve 7, a control groove 8, a moving groove 9, a moving block 10, and a push block 11. Multiple moving plates 3 are fixedly connected to one side of the control sleeve 5. The fixed sleeve 4 is fixedly installed at one end of the buffer tube 1. The control sleeve 5 is rotatably installed on the outside of the fixed sleeve 4. Multiple moving blocks 10 are arranged along a spiral line inside the moving plates 3. The control block 6 is slidably installed in the control groove 8. The control sleeve 7 is slidably installed on the outside of the fixed sleeve 4. The control groove 8 is inclined. The control sleeve 7 is located inside the control sleeve 7. The moving groove 9 is spirally located outside the control sleeve 7. The push block 11 is fixedly connected to one side of the control block 6. The fixed sleeve 4 is equipped with a locking mechanism, which includes a locking sleeve 12, a locking block 13, a locking spring 14, a locking rod 15, a lock hole 16, a lock plate 17, and a cylindrical block 18. The locking sleeve 12 is slidably installed on the outside of the fixed sleeve 4. Multiple locking blocks 13 are movably arranged on one side of the control sleeve 5. The two ends of the locking spring 14 are respectively connected to two adjacent locking blocks 13. The locking rod 15 is fixedly connected to one side of the locking sleeve 12. The lock hole 16 is opened on the lock plate 17. Multiple cylindrical blocks 18 are fixedly installed on the outside of the fixed sleeve 4.

[0029] A piston 19 is movably provided inside the buffer tube 1, and a connecting rod 20 is connected to one side of the piston 19. One end of the connecting rod 20 slides through one end of the buffer tube 1.

[0030] The end of the connecting rod 20 that extends out of the buffer tube 1 is fixedly connected to a handle 21.

[0031] In this embodiment, when chemical reagent sampling is required, the connecting rod 20 is first released from its fixed position. The operator then grasps the handle 21 and pushes it to one side. At this time, the connecting rod 20 drives the piston 19 to move inside the buffer tube 1, causing the piston 19 to press against one end of the buffer tube. Next, the sampling tube 2 is immersed in the chemical reagent to be sampled, and then the handle 21 is slowly pulled in the opposite direction. The connecting rod 20 drives the piston 19 to move inward inside the buffer tube 1, creating a negative pressure inside the buffer tube 1. The reagent at the front end of the sampling tube 2 is drawn into the buffer tube 1. After sampling is completed, the front end of the sampling tube 2 can be sealed, and then the connecting rod 20 can be re-fixed and stored. Alternatively, the sampler can be moved to the target container, and the handle 21 can be pushed again. At this time, the connecting rod 20 drives the piston 19 to move inside the buffer tube 1, and the reagent in the buffer tube 1 is pushed out through the sampling tube 2, completing the sampling transfer.

[0032] Please see Figures 3-5 As a further implementation of the overall equipment: multiple locking rails 22 are fixedly provided on one side of the control sleeve 5, and a locking groove 23 is provided on one side of the locking block 13, with the locking rails 22 and the locking groove 23 fitting together.

[0033] A locking spring 24 is movably sleeved on the outside of the locking rod 15. The locking spring 24 is connected to one side of the locking sleeve 12, and the other end of the locking spring 24 is in contact with the locking plate 17.

[0034] A locking wheel 25 is provided on one side of the locking block 13, which is rotated and engages between the two cylindrical blocks 18.

[0035] Multiple push springs 26 are fixedly connected to one side of the push block 11, and a push plate 27 is connected to the other end of the push spring 26.

[0036] Multiple rubber strips 28 are fixedly provided on one side of the push plate 27.

[0037] More specifically, when it is necessary to release the connecting rod 20, first rotate the locking plate 17 so that the locking plate 17 drives the lock hole 16 to rotate to a position concentric with the locking rod 15. Then push the locking sleeve 12, which will cause the locking rod 15 to slide into the lock hole 16. The locking sleeve 12 will cooperate with the locking plate 17 to compress the locking spring 24. Then the locking sleeve 12 will no longer limit the outer side of the locking wheel 25. Then rotate the control sleeve 5 in the forward direction. The control sleeve 5 will drive the locking block 13 and the locking wheel 25 to rotate in the forward direction, which will be driven by multiple locking rails 22 on one side and locking grooves 23. Then the locking wheel 25 will roll out between the two cylindrical blocks 18, and the locking wheel 25 will drive the locking block 13 to slide outward along the locking rails 22 and locking grooves 23, so that the locking block 13... 3. The locking spring 14 is stretched outwards, and at the same time, the control sleeve 5 drives multiple moving blocks 10 to slide along the moving groove 9 through the moving plate 3 fixed on the other side. Due to the spiral arrangement of the moving blocks 10 and the spiral structure of the moving groove 9, the control sleeve 7 slides along the fixed sleeve 4, causing the control sleeve 7 to drive the control groove 8, which is inclined on the inner side, to slide. Then, the control block 6 drives the push block 11 to move outwards, increasing the distance between the push block 11 and the push plate 27. Then, the push spring 26 slowly resets, and then the push spring 26 fully resets. Then, the push block 11 continues to move outwards, causing the push block 11 to drive the push plate 27 to move outwards through the push spring 26, so that the inner wall of the push plate 27 no longer contacts the outer wall of the connecting rod 20. When it is necessary to connect... When rod 20 is re-fixed, firstly, the control sleeve 5 is rotated in the reverse direction, causing the control sleeve 5 to drive the locking block 13 and locking wheel 25 to rotate in the reverse direction through the locking rail 22 and locking groove 23. The control sleeve 5 also drives the moving block 10 to slide in the reverse direction along the moving groove 9 through the moving plate 3, thereby causing the control sleeve 7 to drive the control groove 8 to slide in the reverse direction. Then, the control block 6 drives the push block 11 to move, causing the push block 11 to drive the push plate 27 to slide inward through the push spring 26. Then, the inner wall of the push plate 27 contacts the outer wall of the connecting plate. Then, the push block 11 continues to move inward, and the distance between the push block 11 and the push plate 27 shortens, causing the push block 11 and the push plate 27 to cooperate in pressing the push spring 26, gradually tightening the push spring 26. Finally, the push plate 27 passes through... Multiple rubber strips 28 on the inner wall clamp and fix the outer wall of the connecting rod 20. At this time, the locking rail 22 and the locking groove 23 cooperate to move the locking block 13 and the locking wheel 25 between the two original cylindrical blocks 18. Then, the locking spring 14 resets and pulls the locking block 13 and the locking wheel 25 to slide inward along the locking rail 22 and the locking groove 23, so that the locking wheel 25 is re-engaged between the two original cylindrical blocks 18. Then, the locking sleeve 12 is released, and the locking spring 24 pushes the locking sleeve 12 to slide back to its original position. Then, the locking sleeve 12 will drive the locking rod 15 to slide back to its original position. When the locking spring 24 is fully reset, the locking rod 15 is no longer in the lock hole 16. Then, the locking plate 17 is rotated again, so that the locking plate 17 drives the lock hole 16 to rotate back to a position that does not correspond to the locking rod 15.Then, the locking rod 15 limits and supports the locking sleeve 12 to one side of the locking plate 17, so that the inner wall of the locking sleeve 12 limits the outer wall of the locking wheel 25, preventing the locking wheel 25 and the locking block 13 from moving outward. This limits the rotation of the control sleeve 5, thus ensuring the stable fixation of the connecting rod 20, preventing accidental unlocking and loosening, and ensuring stable storage.

[0038] In summary, when using or operating the entire device: First, release the connecting rod 20. The operator then grasps the handle 21 and pushes it to one side. The connecting rod 20 moves the piston 19 within the buffer tube 1, causing the piston 19 to press against one end of the buffer tube. Next, immerse the sampling tube 2 into the chemical reagent to be sampled. Then, slowly pull the handle 21 in the opposite direction. The connecting rod 20 moves the piston 19 inward within the buffer tube 1, creating a negative pressure. The reagent at the tip of the sampling tube 2 is drawn into the buffer tube 1. After sampling, the tip of the sampling tube 2 can be sealed, and the connecting rod 20 can be re-secured before storage. Alternatively, the sampler can be moved to the target container, and the handle 21 can be pushed again. This time, the connecting rod 20 moves the piston 19 within the buffer tube 1, and the reagent in the buffer tube 1 is pushed out through the sampling tube 2, completing the sample transfer.

[0039] When it is necessary to release the connecting rod 20, first rotate the locking plate 17, causing the locking plate 17 to rotate the lock hole 16 to a position concentric with the locking rod 15. Then push the locking sleeve 12, which will cause the locking rod 15 to slide into the lock hole 16. The locking sleeve 12 will cooperate with the locking plate 17 to compress the locking spring 24. Then the locking sleeve 12 will no longer limit the outer side of the locking wheel 25. Then rotate the control sleeve 5 in the forward direction. The control sleeve 5 will drive the locking block 13 and the locking wheel 25 to rotate in the forward direction, which will be driven by multiple locking rails 22 on one side and locking grooves 23. Then the locking wheel 25 will roll out between the two cylindrical blocks 18, and the locking wheel 25 will drive the locking block 13 to slide outward along the locking rails 22 and locking grooves 23, so that the locking block 13 drives the lock. The fixed spring 14 is stretched outwards, while the control sleeve 5 drives multiple moving blocks 10 to slide along the moving groove 9 via the moving plate 3 fixed on the other side. Due to the spiral arrangement of the moving blocks 10 and the spiral structure of the moving groove 9, the control sleeve 7 slides along the fixed sleeve 4, causing the control sleeve 7 to drive the control groove 8, which is inclined on the inner side, to slide. Then, the control block 6 drives the push block 11 to move outwards, increasing the distance between the push block 11 and the push plate 27. Then, the push spring 26 slowly returns to its original position, and then the push spring 26 fully returns to its original position. The push block 11 continues to move outwards, causing the push block 11 to drive the push plate 27 to move outwards via the push spring 26, so that the inner wall of the push plate 27 no longer contacts the outer wall of the connecting rod 20. When it is necessary to move the connecting rod 20... When re-fixing, firstly, rotate the control sleeve 5 in the reverse direction. This causes the control sleeve 5 to drive the locking block 13 and locking wheel 25 to rotate in the opposite direction via the locking rail 22 and locking groove 23. The control sleeve 5 also causes the moving block 10 to slide in the opposite direction along the moving groove 9 via the moving plate 3. This causes the control sleeve 7 to slide in the opposite direction along the control groove 8. Then, the control block 6 drives the push block 11 to move, causing the push block 11 to drive the push plate 27 to slide inward via the push spring 26. The inner wall of the push plate 27 then contacts the outer wall of the connecting plate. The push block 11 continues to move inward, shortening the distance between the push block 11 and the push plate 27. This allows the push block 11 and the push plate 27 to work together to press against the push spring 26, gradually tightening it. Finally, the push plate 27... Multiple rubber strips 28 on the inner wall clamp and fix the outer wall of the connecting rod 20. At this time, the locking rail 22 and the locking groove 23 cooperate to move the locking block 13 and the locking wheel 25 between the two original cylindrical blocks 18. Then, the locking spring 14 resets and pulls the locking block 13 and the locking wheel 25 to slide inward along the locking rail 22 and the locking groove 23, so that the locking wheel 25 is re-engaged between the two original cylindrical blocks 18. Then, the locking sleeve 12 is released, and the locking spring 24 pushes the locking sleeve 12 to slide back to its original position. Then, the locking sleeve 12 will drive the locking rod 15 to slide back to its original position. When the locking spring 24 is fully reset, the locking rod 15 is no longer in the lock hole 16. Then, the locking plate 17 is rotated again, so that the locking plate 17 drives the lock hole 16 to rotate back to a position that does not correspond to the locking rod 15.Then, the locking rod 15 limits and supports the locking sleeve 12 to one side of the locking plate 17, so that the inner wall of the locking sleeve 12 limits the outer wall of the locking wheel 25, preventing the locking wheel 25 and the locking block 13 from moving outward. This limits the rotation of the control sleeve 5, thus ensuring the stable fixation of the connecting rod 20, preventing accidental unlocking and loosening, and ensuring stable storage.
