Description

Technical Field

[0001] This utility model relates to the field of sample inlet tube technology, and in particular to a support device for the sample inlet tube of an ICP device. Background Technology

[0002] ICP equipment is a precision instrument used for elemental analysis, widely applied in fields such as environmental monitoring, food safety, and materials science. It uses high-temperature plasma to excite elements in a sample into ionic states, and then detects their composition and content through spectroscopy or mass spectrometry. The ICP injection tube is a key component of the sample introduction system, and its main function is to efficiently and stably deliver liquid or gaseous samples into the plasma torch. Its design directly affects the sensitivity and accuracy of the analysis. It is usually required to be corrosion-resistant, high-temperature resistant, able to maintain a stable sample flow rate, and adaptable to the chemical properties of different samples.

[0003] The relative height between the injection tube and the nebulizer directly affects the sample solution intake efficiency and nebulization effect. However, the support device of the injection tube in traditional ICP equipment cannot precisely adjust the height of the injection tube, which may lead to unstable sample flow rate or uneven nebulization, thereby reducing analytical sensitivity and repeatability. An inappropriate injection height may also cause discontinuous aerosol generation, resulting in signal fluctuations or increased noise, affecting the accuracy of detection results. At the same time, it may cause liquid backflow or salt accumulation in the nebulizer nozzle, increasing the probability of blockage and even damaging precision components.

[0004] Therefore, to address the problem that the support device for the injection tube in traditional ICP equipment cannot accurately adjust the height of the injection tube, which affects the accuracy of the test results, increases the probability of blockage, and may even damage precision components, a support device for the injection tube of ICP equipment that can accurately control the height of the injection tube can be designed to solve the above problems. Utility Model Content

[0005] To overcome the problem that the support device for the injection tube in traditional ICP equipment cannot accurately adjust the height of the injection tube, which affects the accuracy of the test results, increases the probability of blockage, and may even damage precision components.

[0006] The technical solution of this utility model is as follows: a support device for the injection tube of an ICP device, including a fixed frame; and a mounting sliding column, the mounting sliding column being fixedly connected above the fixed frame, a rack being slidably connected inside the mounting sliding column, a slot being provided on one side of the mounting sliding column, a mounting disc being provided on the slotted side, a gear being fixedly connected to the mounting disc, a rotating sleeve being rotatably connected to the center of the mounting disc, a fixed support being fixedly connected to the rotating sleeve, a buckle being rotatably connected to the fixed support, the buckle being movably connected to the gear, and a rotating threaded strip being fixedly connected to the back of the mounting disc, the rotating threaded strip being meshed with the rack.

[0007] Preferably, when adjusting the height, the buckle is firmly engaged in the gap between the gears. Then, the mounting disc is rotated, causing the mounting disc to drive the rotating threaded bar to rotate as well. This causes the rack meshing with the rotating threaded bar to move linearly, allowing the rack to slide on the mounting sliding column, thus changing the height. If a reverse height adjustment is required, the buckle is removed, and the rotating sleeve is rotated, causing the rotating sleeve to drive the fixed support to rotate. The fixed support then drives the buckle to rotate, causing the buckle to be fixed to the gear in the opposite direction and rotate, thus completing the reverse height adjustment.

[0008] Preferably, a U-shaped fixing bracket is rotatably connected to the back of the mounting disc, and the U-shaped fixing bracket is fixedly connected to the mounting sliding column.

[0009] Preferably, a control handle is fixedly connected to the rotating sleeve, and an adjustable telescopic rod is fixedly connected to the top of the rack.

[0010] Preferably, the output end of the adjustable telescopic rod is fixedly connected to a clamping sleeve, and the adjustable telescopic rod is used to drive the clamping sleeve to perform linear motion.

[0011] Preferably, the clamping sleeve is threaded with tightening bolts on both sides, and the sample inlet tube body is fixedly connected in the middle of the clamping sleeve.

[0012] Preferably, a plasma torch is fixedly connected to the fixed frame, and a tube cap is fixedly connected above the plasma torch.

[0013] Preferably, the tube cap has a through hole, which is fixedly connected to the sample injection tube body, and a sealing rubber ring is provided inside the tube cap, which is fixedly connected to the plasma torch.

[0014] The beneficial effects of this utility model are:

[0015] By utilizing racks, gears, and rotating threaded strips, the height of the sample inlet tube can be precisely adjusted, accurately matching the sample inlet requirements of the nebulizer. This ensures that the sample solution forms a uniform aerosol at the optimal flow rate, thereby improving nebulization efficiency and enhancing the stability and sensitivity of the detection signal. Furthermore, appropriately lowering the sample inlet height can reduce the risk of nebulizer clogging, while increasing the height can reduce sample volatilization loss during transmission and extend the life of key components.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a support device for an ICP device injection tube, including a fixed frame 1 and a mounting sliding column 2. The mounting sliding column 2 is fixedly connected to the top of the fixed frame 1. A rack 3 is slidably connected inside the mounting sliding column 2. A slot 201 is provided on one side of the mounting sliding column 2, and a mounting disc 5 is provided on one side of the slot 201. A gear 501 is fixedly connected to the mounting disc 5. A rotating sleeve 6 is rotatably connected to the center of the mounting disc 5. A fixed support 7 is fixedly connected to the rotating sleeve 6. A buckle 8 is rotatably connected to the fixed support 7. The buckle 8 and the gear 501 are movably connected. A rotating threaded strip 10 is fixedly connected to the back of the mounting disc 5. The rotating threaded bar 10 and the rack 3 are engaged. When adjusting the height, the buckle 8 is firmly locked in the gap of the gear 501. Then, the mounting disc 5 is rotated, causing the rotating threaded bar 10 to rotate together. This causes the rack 3, which is engaged with the rotating threaded bar 10, to move linearly. The rack 3 then slides on the mounting sliding column 2, thus changing the height. If the height needs to be adjusted in the opposite direction, the buckle 8 is removed, and the rotating sleeve 6 is rotated. This causes the rotating sleeve 6 to rotate the fixed support 7, which in turn causes the buckle 8 to rotate. The buckle 8 is then fixed in the opposite direction on the gear 501, thus completing the height adjustment in the opposite direction.

[0024] Please see Figures 1-5In this embodiment, a U-shaped fixing frame 4 is rotatably connected to the back of the mounting disc 5. The U-shaped fixing frame 4 is fixedly connected to the mounting sliding column 2. The mounting disc 5 is fixed to the mounting sliding column 2 by the U-shaped fixing frame 4 for movement limitation, but without causing movement interference, making the structure more complete. A control handle 9 is fixedly connected to the rotating sleeve 6, and an adjustable telescopic rod 11 is fixedly connected to the top of the rack 3. By rotating the control handle 9, the rotating sleeve 6 is driven to rotate, thereby controlling the mounting disc 5. The adjustable telescopic rod 11 is used for power output. A clamping sleeve 12 is fixedly connected to the output end of the adjustable telescopic rod 11. The adjustable telescopic rod 11 is used to drive the clamping sleeve 12 to perform linear motion. By driving the clamping sleeve 12 to perform reciprocating linear motion through the adjustable telescopic rod 11, the center of the clamping sleeve 12 is aligned, which is convenient for flexible adjustment.

[0025] Please see Figures 1-3 In this embodiment, tightening bolts 13 are threadedly connected to both sides of the clamping sleeve 12, and the sample injection tube body 14 is fixedly connected to the middle of the clamping sleeve 12. The sample injection tube body 14 is fixed between the clamping sleeves 12 and the tightening bolts 13 are used to firmly fix the sample injection tube body 14. The plasma torch 15 is fixedly connected to the fixed frame 1, and the tube cap 16 is fixedly connected to the top of the plasma torch 15. The plasma torch 15 is the main container for testing. The tube cap 16 is used to seal and protect the plasma torch 15. The tube cap 16 is provided with a through hole 1601, which is fixedly connected to the sample injection tube body 14. A sealing rubber ring 1602 is provided inside the tube cap 16, which is fixedly connected to the plasma torch 15. The sample injection tube body 14 enters the plasma torch 15 through the through hole 1601, and the sealing rubber ring 1602 ensures the sealing of the transportation and reaction process.

[0026] During operation, the sample inlet tube body 14 is fixed between the clamping sleeves 12, and the sample inlet tube body 14 is firmly fixed with the tightening bolts 13. The adjustable telescopic rod 11 drives the clamping sleeve 12 to move back and forth in a straight line, so that the clamping sleeve 12 is aligned with the plasma torch 15. Then, the sample inlet tube body 14 is inserted into the plasma torch 15 through the through hole 1601. At the same time, the sealing rubber ring 1602 ensures the airtightness of the transportation and reaction process. When height adjustment is required, the buckle 8 is firmly locked between the gaps of the gear 501. Then, the control handle 9 is turned to drive the rotating sleeve 6 to rotate. The mounting disc 5 is rotated, causing the rotating threaded bar 10 to rotate as well. This causes the rack 3 meshing with the rotating threaded bar 10 to move linearly, allowing the rack 3 to slide on the mounting sliding column 2. This changes the height of the rack 3, thereby adjusting the height of the sample inlet tube body 14. If a reverse height adjustment is needed, the buckle 8 is removed, and the rotating sleeve 6 is rotated. This causes the rotating sleeve 6 to rotate the fixed support 7, which in turn causes the buckle 8 to rotate. The buckle 8 is then fixed in the reverse direction on the gear 501 for rotation, completing the reverse height adjustment.

[0027] Through the above steps, the height of the sample inlet tube can be precisely adjusted using rack 3, gear 501, and rotating threaded strip 10. This allows for precise matching of the nebulizer's sample inlet requirements, ensuring that the sample solution forms a uniform aerosol at the optimal flow rate, thereby improving nebulization efficiency and enhancing the stability and sensitivity of the detection signal. Furthermore, appropriately lowering the sample inlet height can reduce the risk of nebulizer clogging, while increasing the height can reduce sample evaporation loss during transmission and extend the lifespan of key components. This addresses the problem that the support device for the sample inlet tube in traditional ICP equipment cannot precisely adjust the height of the sample inlet tube, affecting the accuracy of detection results, increasing the probability of clogging, and even damaging precision components.
