Description

Technical Field

[0001] This invention relates to the field of oil testing technology, specifically to a testing device for chemical oil analysis. Background Technology

[0002] The purity and impurity content of chemical oils directly determine their performance, storage stability, and application safety. Accurate and efficient analysis and testing are core aspects of chemical production and quality control. Spectroscopic detection technology, due to its advantages of rapid, accurate, and non-destructive testing, has been widely applied in the field of chemical oil analysis. Among these technologies, quantum dot fluorescence and quantum dot luminescence, with their unique optical properties such as broad excitation spectra, narrow and symmetrical emission spectra, high fluorescence quantum yield, and good photostability, have become the preferred solution for trace analysis, providing core technical support for high-precision oil detection.

[0003] Authorization announcement number CN119125059B discloses a near-infrared spectral analysis and detection device for petroleum products, relating to the field of petroleum product detection technology. The device includes an analytical instrument with a detection cavity inside. A limiting ring is fixedly installed at the bottom of the detection cavity, and a sample dish is fixedly installed inside the limiting ring. A cover is hinged to the top of the analytical instrument, and a cylinder is fixedly installed on the top of the cover. A frame is fixedly connected to the output end of the cylinder, and a motor is fixedly installed inside the frame. A discharge mechanism is fixedly connected to the output end of the motor. The motor drives the discharge mechanism to rotate along the circumference of the sample dish, and the discharge mechanism applies the test sample onto the sample dish during rotation. This invention effectively avoids the deviations caused by manual coating of petroleum products, allowing the petroleum products to adhere more evenly to the bottom of the sample dish. This results in more accurate spectral data under near-infrared light irradiation, leading to more precise near-infrared spectral analysis results. In this invention, the oil is pumped into a rotating rod and flows into the sample dish through a discharge port. The rotating rod rolls inside the sample dish, coating the interior with oil. However, a significant amount of oil remains on the rotating rod and other components during coating, resulting in sample waste. Furthermore, the oil requires considerable cleaning and drying after testing before reuse, reducing testing efficiency. The rotating rod's movement also leaves air bubbles inside the oil, affecting the accuracy of the test. Summary of the Invention

[0004] The purpose of this invention is to provide a detection device for chemical oil analysis.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the detection device for chemical oil analysis; 1. The device is equipped with a drive assembly that allows the push rod to move vertically. When the push rod moves vertically, it pushes the piston. When the piston is pushed, it slides inside the sample cylinder. When the piston slides, it pushes the oil inside the sample cylinder into the sample dish. Since the oil inside the sample cylinder is slightly more than the volume inside the sample dish, the oil can fill the placement cavity when it enters the sample dish. This makes the operation convenient and improves the accuracy of the detection. 2. After the oil testing is completed, the sample dish and sample measuring cylinder can be disassembled using the mounting and locking parts. After disassembly, the sample dish and sample measuring cylinder are placed in the cleaning solvent for cleaning. Then, new sample dishes and sample measuring cylinders can be used to continue to hold and test the oil. The cleaning is simple and the operation is convenient. 3. Twisting the rotating block will cause the rotating ring to rotate. When the rotating ring rotates, it can cause the sealing cover to rotate. When the sealing cover rotates, it can slide threadedly inside the sample dish. At the same time, the rotating ring can slide threadedly on the outer surface of the feed cylinder. When the sealing cover slides threadedly, the volume of the placement cavity can be adjusted, so that the placement cavity can be adjusted according to the amount of oil, reducing the consumption during oil testing. 4. The piston is designed to compress the air inside the sample cylinder when it slides downwards. The compressed air is discharged through the first through hole and the second vent hole. The second vent hole can be sealed by a float ball. After the air inside the sample cylinder is discharged, the piston will continue to move downwards to push the oil into the placement chamber of the sample dish. After the oil enters the placement chamber, it will compress the air inside the placement chamber. The compressed air inside the placement chamber will be discharged through the first vent hole. When the oil fills the placement chamber, the float ball can seal the arc-shaped limiting groove to facilitate the discharge of air after the oil enters the placement chamber and avoid affecting the oil detection. 5. A connecting rod is provided that can rotate with the assistance of auxiliary components. When the connecting rod rotates, it can drive the annular placement frame to rotate, and when the annular placement frame rotates, it can drive the sample dish to rotate. When the sample dish rotates, its bottom can face the side of the near-infrared light irradiated in the detection chamber, which can reduce the obstruction of oil by the components and improve the accuracy of oil detection in the sample dish.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0020] Please see Figures 1-7 , Figure 10 and Figure 14 This invention provides an embodiment of a chemical oil analysis detection device, comprising: an analyzer 100, an analyzer 100 equipped with a display screen 200 for operation, an analyzer 100 having a detection chamber 300 inside, a light shield 400 slidably connected between the detection chamber 300 and the analyzer 100, an auxiliary detection mechanism 600 inside the detection chamber 300, a sample dish 500 for placing oil on the auxiliary detection mechanism 600, a scale indicating the capacity (unit of measurement of the scale is mL) on the surface of the sample dish 500, the sample dish 500 including a sealing cover 510 and a sample measuring cylinder 520 for temporarily storing oil, the sample measuring cylinder 520 having a scale indicating the capacity (unit of measurement of the scale is mL) on its surface. It should be noted that before testing, the oil needs to be poured into the sample measuring cylinder 520, and the volume of oil (in milliliters) should be determined according to the scale on the sample measuring cylinder 520. The volume of the placement cavity of the sample dish 500 should be adjusted by rotating the sealing cover 510 (it should be noted that the volume of the placement cavity should be slightly smaller than the volume of oil, taking into account the loss of oil when entering the sample dish 500). After the volume of the placement cavity is adjusted, the sample measuring cylinder 520 can be inserted into the sample dish 500. The sample dish 500 is then placed on the auxiliary testing mechanism 600. After the sample dish 500 is placed, the light shield 400 is closed. After the light shield 400 is closed, the auxiliary detection mechanism 600 can push the oil inside the sample measuring cylinder 520 into the sample dish 500. Then, the auxiliary detection mechanism 600 can continue to work to remove the sample measuring cylinder 520 from the sample dish 500 and move it to the corresponding position. While the sample measuring cylinder 520 is moving, the auxiliary detection mechanism 600 can rotate the sample dish 500. When the sample dish 500 is rotated to a specified angle, the analyzer 100 can detect the quality of the oil. The analyzer 100 analyzes the composition and properties of the oil by using the spectral data obtained after irradiation with near-infrared light.

[0021] like Figures 1-7 , Figure 10 and Figure 14 As shown, a sealing cover plate 510 is threadedly connected to the inner side of the sample dish 500. A storage cavity for storing oil is provided between the sample dish 500 and the sealing cover plate 510. The sealing cover plate 510 is used to adjust the size of the storage cavity by rotating the thread. A sample measuring cylinder 520 is provided at the center of the bottom of the inner side of the sample dish 500 through a groove. The top of the sample measuring cylinder 520 passes through the through hole on the surface of the sealing cover plate 510. It can be imagined that after the oil is injected, the bottom of the sample measuring cylinder 520 can be inserted into the inner groove of the sample dish 500 through the through hole on the surface of the sealed cover plate 510. The groove can limit the sample measuring cylinder 520 laterally. The rotating sealing cover 510 can slide inside the sample dish 500 through the engagement of the thread and the thread groove. When the sealing cover 510 slides, the volume of the placement cavity will be adjusted. After the volume of the placement cavity is adjusted, the oil inside the sample measuring cylinder 520 can be pushed into the sample dish 500.

[0022] like Figures 1-7 , Figure 9 , Figure 12 and Figure 14 As shown, the closed cover plate 510 includes a rotating ring 511 for rotating the closed cover plate 510 by twisting it. The rotating ring 511 is fixedly connected through the center of the closed cover plate 510, and two rotating blocks are symmetrically fixed on the outer surface of the rotating ring 511. It is worth noting that turning the rotating block will cause the rotating ring 511 to rotate. When the rotating ring 511 rotates, it can cause the sealing cover plate 510 to rotate. When the sealing cover plate 510 rotates, it can slide threadedly inside the sample dish 500. At the same time, the rotating ring 511 can slide threadedly on the outer surface of the feed cylinder 531. When the sealing cover plate 510 slides threadedly, the volume of the placement cavity can be adjusted.

[0023] like Figures 1-8 , Figure 10 , Figure 14 , Figure 15 and Figure 17 As shown, the sample measuring cylinder 520 includes a feed hole 521 for injecting oil into the sample measuring cylinder 520 and a piston 524 for pushing the oil into the sample dish 500. The feed hole 521 is provided on the upper part of the outer surface of the sample measuring cylinder 520. The piston 524 is slidably connected inside the sample measuring cylinder 520. A push rod 523 is installed through the center of the piston 524. A cover plate 522 is sleeved on the outer surface of the push rod 523. The bottom groove of the cover plate 522 is threadedly connected to the top of the sample measuring cylinder 520. The cover plate 522 and the push rod 523 are vertically slidably connected by a limiting member. When the piston 524 moves vertically inside the sample dish 500, it can squeeze the oil into the placement cavity, and the oil can be spread flat in the placement cavity, improving the detection effect of the oil. It is understood that the oil is injected into the sample measuring cylinder 520 through the feed port 521. After the oil is injected, the sample measuring cylinder 520 can be inserted into the sample dish 500. At this time, rotating the sample measuring cylinder 520 will open the feed structure 530. After the feed structure 530 is opened, the drive assembly 630 can push the push rod 523 downward. When the push rod 523 is pushed, it will slide vertically inside the cover plate 522. When the push rod 523 slides vertically, it can move the piston 5. When piston 524 is pushed, it slides inside the sample measuring cylinder 520. When piston 524 slides, it can push the oil inside the sample measuring cylinder 520 into the sample dish 500. Since the oil inside the sample measuring cylinder 520 is slightly more than the volume inside the sample dish 500, the oil can be spread out when it enters the sample dish 500. When piston 524 pushes the oil, it can expel the air inside the sample measuring cylinder 520 and the sample dish 500 through the cooperation of the exhaust structure 540.

[0024] like Figures 1-14As shown, the sample dish 500 also includes a feeding structure 530, which includes a feeding cylinder 531 and a slot 536. The feeding cylinder 531 is threadedly connected to the inner side of the rotating ring 511. The feeding cylinder 531 is sleeved on the outer surface of the sample measuring cylinder 520. The bottom of the feeding cylinder 531 is fixedly connected to the center of the bottom of the sample dish 500. At least four feeding ports 532 are opened through the outer surface of the feeding cylinder 531 in a circular array. A first collection groove 533 is opened on the inner wall of the feeding cylinder 531 near the feeding port 532. The first collection groove 533 is connected to the feeding port 532. The inner wall of the feeding cylinder 531 is opened with... The feeding structure 530 includes a rotating groove 534, a rotating groove 535 extending through the rotating groove 534 and the first collection groove 533, and at least four slots 536 arranged in a ring array at the top of the feeding cylinder 531. The bottom of the slots 536 is connected to the rotating groove 534. The feeding structure 530 also includes a first sealing plate 537 and a positioning block 539. The first sealing plate 537 is slidably connected to the inside of the feeding port 532 and the first collection groove 533. A rotating plate 538 is fixedly installed on the top of the first sealing plate 537. The rotating plate 538 is slidably connected to the inside of the rotating groove 534. A positioning block 539 is fixedly installed on the top of the rotating plate 538. It should be understood that inserting the insert 5313 into the slot 536 and sliding it vertically will cause the positioning slot 5314 to fit onto the outer surface of the positioning block 539 when the insert 5313 slides into the rotating groove 534. At this time, rotating the sample measuring cylinder 520 can cause the insert 5313 to rotate inside the rotating groove 534. When the insert 5313 rotates, it can drive the positioning block 539 to rotate through the positioning groove 5314. When the positioning block 539 rotates, it will drive the rotating plate 538 to rotate. When the rotating plate 538 rotates, it can rotate in the rotating groove 535. When the rotating plate 538 rotates, it can drive the first sealing plate 537 to rotate. When the first sealing plate 537 rotates, it can slide between the feed inlet 532 and the first collection groove 533. When the first sealing plate 537 slides into the first collection groove 533, it can open the feed inlet 532. After the feed inlet 532 is opened, the oil will enter the sample dish 500 from the sample measuring cylinder 520.

[0025] like Figures 1-13 As shown, the feeding structure 530 also includes a second collection groove 5311 and a positioning groove 5314. At least four second collection grooves 5311 are provided in a ring array on the lower part of the outer surface of the sample measuring cylinder 520. Each second collection groove 5311 has a discharge port 5310 through it. A second sealing plate 5312 is vertically slidably connected inside the second collection groove 5311. An insert block 5313 that mates with the slot 536 is fixedly installed on the upper surface of the second sealing plate 5312. A positioning groove 5314 that mates with the positioning block 539 is provided at the bottom of the insert block 5313. It is conceivable that pulling the sample measuring cylinder 520 can insert it into the feed cylinder 531. When the sample measuring cylinder 520 is inserted into the feed cylinder 531, it will cause the insert block 5313 to slide downward in the slot 536. When the insert block 5313 slides out of the bottom of the slot 536, it will slide into the rotating groove 534. When the insert block 5313 slides into the rotating groove 534, it can cause the positioning groove 5314 to engage with the side of the positioning block 539. At this time, continue to push the sample measuring cylinder 520 downward until it slides into the groove of the sample dish 500. When the sample measuring cylinder 520 continues to slide downward, because the insert block 5313 is blocked by the rotating groove 534, the insert block 5313 will push the second sealing plate 5312 upward. When the sealing plate 5312 moves, it can slide inside the second collection groove 5311. When the top of the second sealing plate 5312 slides to the top of the second collection groove 5311, it can open the discharge port 5310. After the discharge port 5310 is opened, it can drive the sample measuring cylinder 520 to rotate through the drive component 630. When the sample measuring cylinder 520 rotates, it will drive the insert block 5313 to rotate in the rotating groove 534. When the insert block 5313 rotates, it can open the feed port 532 through the cooperation of the parts. At the same time, the rotation of the sample measuring cylinder 520 will drive the discharge port 5310 to dock with the feed port 532. After the discharge port 5310 docks with the feed port 532, the piston 524 moves downward to push the oil into the sample dish 500. After the oil is pushed into the sample dish 500, the sample measuring cylinder 520 can be rotated in the opposite direction. When the sample measuring cylinder 520 is rotated in the opposite direction, the feed port 532 can be closed by the cooperation of the insert block 5313 and the second sealing plate 5312 and other components. After the feed port 532 is closed, pulling the sample measuring cylinder 520 upward can drive the insert block 5313 to slide out of the slot 536.

[0026] like Figures 1-10 , Figure 12 , Figure 14 , Figure 15 and Figure 17 As shown, the sample dish 500 also includes an exhaust structure 540, which includes a first exhaust hole 541 and a float 543. The top of the closed cover plate 510 is provided with the first exhaust hole 541 in a ring array. The inner center of the push rod 523 is provided with a second exhaust hole 544. The bottom end of the push rod 523 is provided with a first through hole 545, the top end of the first through hole 545 is connected to the bottom end of the second exhaust hole 544. The outer surface of the push rod 523 is provided with a second through hole 546, the surface of the second through hole 546 is connected to the top end of the second exhaust hole 544. Both ends of the first exhaust hole 541 and the second exhaust hole 544 are connected with arc-shaped limiting grooves 542. The interior of the first exhaust hole 541 and the second exhaust hole 544 is provided with a float 543. It is worth noting that after the sample measuring cylinder 520 is inserted into the feed cylinder 531, the drive assembly 630 can push the push rod 523 to slide downwards vertically. When the push rod 523 slides, it can push the piston 524 to slide inside the sample measuring cylinder 520. When the piston 524 slides downwards, it will compress the air inside the sample measuring cylinder 520. When the air is compressed, it will enter the second exhaust port 544 through the first through hole 545 and blow the float 543. When the float 543 is blown, the air can pass through the float 543 and the second exhaust port 544. The oil enters the second through hole 546 through the gap between the two, and air can be discharged through the second through hole 546. After the air inside the sample measuring cylinder 520 is discharged, the piston 524 will continue to move downward. When the piston 524 moves downward, the oil will enter the interior of the second vent hole 544 through the first through hole 545. When the oil enters the interior of the second vent hole 544, the float ball 543 will float on the surface of the oil and move upward with the oil in the second vent hole 544. When the float ball 543 floats into the arc-shaped limiting groove 542, it will cause resistance and seal the arc-shaped limiting groove 542. After the air inside the sample measuring cylinder 520 is expelled, the feed port 532 can be opened by rotating it. After the feed port 532 is opened, the piston 524 continues to move downward to push the oil into the placement chamber of the sample dish 500. After the oil enters the placement chamber, it will compress the air inside the placement chamber. When the air inside the placement chamber is compressed, it will enter the first vent hole 541 and blow the float 543. When the float 543 is blown, the air can be discharged through the gap between the float 543 and the first vent hole 541. When the oil fills the placement chamber, the oil will enter the first vent hole 541. When the oil enters the first vent hole 541, the float 543 will float on the surface of the oil and move upward with the oil in the first vent hole 541. When the float 543 floats into the arc-shaped limiting groove 542, it will cause resistance and seal the arc-shaped limiting groove 542.

[0027] like Figures 1-7 , Figure 10 , Figure 14 and Figure 16 As shown, the auxiliary detection mechanism 600 also includes a positioning component 610, an auxiliary component 620, and a driving component 630. The positioning component 610 includes an annular placement frame 611 and a slider 614. The annular placement frame 611 is fitted onto the lower part of the outer surface of the sample dish 500. Two connecting rods 612 are symmetrically fixed on the outer surface of the annular placement frame 611. The other end of the connecting rod 612 is rotatably installed on the inner wall of the detection cavity 300. The end of the connecting rod 612 near the annular placement frame 611 is fixed to the sample dish 500 by a locking device. Two sliding grooves 613 are symmetrically opened on the outer surface of the sample dish 500. Two sliders 614 that cooperate with the sliding grooves 613 are symmetrically fixed on the inner side of the annular placement frame 611. It is clear that when the sample dish 500 is placed inside the annular placement frame 611, it will cause the slide groove 613 to slide and engage with the slider 614. When the slide groove 613 slides completely to the side of the slider 614, the annular placement frame 611 will also slide into the interior of the annular placement frame 611. At this time, the sample dish 500 can be fixed by operating the locking device on the connecting rod 612. When the sample measuring cylinder 520 is removed from the sample dish 500, the connecting rod 612 can rotate with the cooperation of the auxiliary component 620. When the connecting rod 612 rotates, it can drive the annular placement frame 611 to rotate. When the annular placement frame 611 rotates, it can drive the sample dish 500 to rotate. When the sample dish 500 rotates, its bottom can face the side of the near-infrared light irradiated in the detection cavity 300, thereby reducing the obstruction of the components and making the oil detection in the sample dish 500 more accurate.

[0028] like Figures 1-7 , Figure 10 , Figure 14 and Figure 16 As shown, the auxiliary component 620 includes a fixed frame 621 and a gear 628. The fixed frame 621 is fixedly installed on the top of the detection cavity 300. A first lead screw 622 is rotatably installed through the inner side of the fixed frame 621. A driving component is installed at one end of the first lead screw 622 and is installed at one end of the fixed frame 621. The driving component can be a motor. A first internal thread slide 623 is threadedly connected to the surface of the first lead screw 622. The first internal thread slide 623 is slidably connected inside the fixed frame 621. The top of the detection cavity 300 is rotatably installed... The device is equipped with a second lead screw 624, which is connected to the first lead screw 622 via a bevel gear set 625. The bevel gear set 625 is generally composed of two bevel gears. The outer surface of the second lead screw 624 is threadedly connected to a second internal thread slide 626. The side of the second internal thread slide 626 is slidably connected to the inner wall of the detection cavity 300. A rack 627 is fixedly installed at the bottom of the second internal thread slide 626. A gear 628 that mates with the rack 627 is fixedly installed on the outer surface of one of the connecting rods 612. It should be understood that when the drive assembly 630 removes the sample measuring cylinder 520 from the sample dish 500, the drive unit can rotate the first lead screw 622. When the first lead screw 622 rotates, it causes the first internal thread slide block 623 to slide laterally within the fixed frame 621. The sliding of the first internal thread slide block 623 can cause the drive assembly 630 and the sample measuring cylinder 520 to move laterally. Simultaneously, the rotation of the first lead screw 622 drives the first bevel gear at its end to rotate. The rotation of the first bevel gear drives the second bevel gear to mesh and rotate. The rotation of the second bevel gear can then drive the... When the second lead screw 624 rotates, it will cause the second internal thread slide 626 to slide downwards against the inner wall of the detection cavity 300. When the second internal thread slide 626 slides downwards, it will cause the rack 627 to move. When the rack 627 moves to the side of the gear 628, the rack 627 will drive the gear 628 to mesh and rotate. When the gear 628 meshes and rotates, it can drive the connecting rod 612 to rotate. When the connecting rod 612 rotates, it can drive the annular placement frame 611 and the sample dish 500 to rotate 90°. The sample dish 500 rotates 90° to facilitate the detection of oil.

[0029] like Figures 1-10 , Figure 14 , Figure 15 and Figure 17 As shown, the drive assembly 630 includes a cylinder 631 and a rotating rod 633. The cylinder 631 is fixedly mounted on the bottom of the first internal thread slide 623. A mounting bracket 632 is fixedly mounted on the output end of the cylinder 631. The rotating rod 633 is rotatably mounted through the bottom of the mounting bracket 632. A drive component is mounted on the top of the rotating rod 633. The drive component can be a motor. The drive component is installed inside the mounting bracket 632. The rotating rod 633 and the push rod 523 are connected through the mounting component. It should be noted that when the sample dish 500 is placed inside the annular placement frame 611, the cylinder 631 can push the mounting bracket 632 and the rotating rod 633 to move vertically when it is working. When the rotating rod 633 moves vertically, it can be connected to the push rod 523 through the mounting part. After the rotating rod 633 is connected to the push rod 523, the cylinder 631 continues to work and pushes the piston 524 to squeeze out the air inside the sample measuring cylinder 520. After the air inside the sample measuring cylinder 520 is squeezed out, the motor can drive the rotating rod 633 to rotate. When the rotating rod 633 rotates, it can drive the push rod 523 to rotate through the mounting part. The rotation of the push rod 523 can drive the sample measuring cylinder 520 to rotate. When the sample measuring cylinder 520 rotates, the feed port 532 can be opened through the operation of the parts. After the feed port 532 is opened, the cylinder 631 continues to work and can push the piston 524 to squeeze the oil inside the sample measuring cylinder 520 into the sample dish 500. Once the oil has completely entered the sample dish 500, the motor will drive the rotating rod 633 to rotate. When the rotating rod 633 rotates, it will drive the sample measuring cylinder 520 to rotate via the push rod 523. When the sample measuring cylinder 520 rotates, the cooperation of the parts will close the feed port 532. After the feed port 532 is closed, the cylinder 631 will operate and the sample measuring cylinder 520 will slide out of the sample dish 500 through the mounting bracket 632 and the rotating rod 633.

[0030] like Figures 1-7 , Figure 14 and Figure 16 As shown, the locking component includes a moving groove 6121 and a pressing block 6125. The moving groove 6121 is provided through the connecting rod 612 and the annular placement frame 611. The outer surface of the connecting rod 612 is threaded with an internal threaded ring 6122. One end of the internal threaded ring 6122 is rotatably connected to a rotating ring 6123. The inner side of the rotating ring 6123 is fixedly installed with a moving rod 6124 located in the moving groove 6121 through an extension block. The pressing block 6125 is fixedly installed at one end of the moving rod 6124 near the annular placement frame 611. It is conceivable that when the sample dish 500 is placed inside the annular placement frame 611, the internal threaded ring 6122 can be rotated. When the internal threaded ring 6122 rotates, it can slide on the surface of the connecting rod 612. When the internal threaded ring 6122 slides, its end will rotate the rotating ring 6123. While the internal threaded ring 6122 and the rotating ring 6123 are rotating, the sliding of the internal threaded ring 6122 will drive the rotating ring 6123 to move horizontally on the outer surface of the connecting rod 612. When the rotating ring 6123 moves, it can drive the moving rod 6124 and the pressing block 6125 to move horizontally in the moving groove 6121 through the extension block. When the pressing block 6125 moves to the side of the sample dish 500, it can be pressed and fixed.

[0031] like Figures 1-8 , Figure 14 , Figure 16 and Figure 17 As shown, the mounting component includes a fixing block 6331 and a slot 6335. The end of the rotating rod 633 is fixedly mounted with the fixing block 6331. A pressing groove 6332 is provided through the side of the fixing block 6331. Both ends of the pressing groove 6332 are movably connected to the slot 6333. The two slots 6333 are connected by an elastic element, which can be a spring. The slot 6333 has an inclined surface. The outer surface of the fixing block 6331 is fitted with a mounting seat 6334. The mounting seat 6334 is fixedly connected to the top of the push rod 523. The outer surface of the mounting seat 6334 is provided with a slot 6335 that engages with the slot 6333. It is worth noting that when the sample dish 500 is installed inside the annular placement frame 611, the operation of the cylinder 631 can push the mounting bracket 632 and the rotating rod 633 to move vertically. When the rotating rod 633 moves vertically, it will cause the fixing block 6331 to move vertically. When the fixing block 6331 moves to the top of the mounting base 6334, the fixing block 6331 can slide against the inner cavity of the mounting base 6334. When the fixing block 6331 slides to the designated position, the mounting base 6334 will press against the inclined surface of the clamping block 6333. When the clamping block 6333 is pressed, it can... The locking block 6333 slides into the pressing groove 6332. When the locking block 6333 slides, it can compress the spring. When the locking block 6333 is pressed into the pressing groove 6332, the fixing block 6331 will continue to move downward to the bottom of the inner cavity of the mounting base 6334. At this time, the fixing block 6331 can drive the locking block 6333 to move to the side of the slot 6335. The locking block 6333 will then be reset by the spring force and engage with the slot 6335. After the locking block 6333 and the slot 6335 are engaged, the rotating rod 633 can be connected to the pushing rod 523. After the oil quality test is completed, the locking block 6333 can be pressed. When the locking block 6333 is pressed into the squeezing groove 6332, the mounting base 6334 can be pulled down. When the mounting base 6334 is pulled down, it will slide out from the side of the fixing block 6331 to disassemble the push rod 523.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
