Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology, and in particular to a precise quantitative sampler for mannan detection. Background Technology
[0002] A quantitative sampler is a tool used to accurately obtain a specific amount of sample, widely used in laboratories, production, and quality control. It ensures consistency in the quantity, quality, or volume of each sample, thereby improving the accuracy and repeatability of experiments. Quantitative samplers are typically used for sampling liquids, powders, or particles to ensure the representativeness and consistency of the sample before analysis.
[0003] In existing technologies, mannan is sampled manually, which leads to inconsistent sample volumes, affecting the accuracy and repeatability of experimental results. In addition, hand contact by operators may introduce contaminants, affecting the purity of the sample and the reliability of the experimental results. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a precise quantitative sampler for mannan detection.
[0005] This utility model is achieved using the following technical solution: a precise quantitative sampler for mannan detection, comprising a shell, a rubber ring slidably connected to the inner wall of the shell, a fixing block fixedly connected to the inner wall of the rubber ring, a threaded rod threadedly connected to the fixing block, a handle fixedly connected to the top of the threaded rod, a slider fixedly connected to the end of the threaded rod away from the handle, a support block fixedly connected to the inner wall of the shell, an inner groove formed inside the support block, the slider rotatably connected to the outer wall of the inner groove, a fixing post fixedly connected to the inner wall of the shell, a fixing rod fixedly connected inside the fixing post, a limit block fixedly connected to the end of the fixing rod away from the fixing post, a spring contacting the outer wall of the fixing rod, and a rubber ring slidably connected to the outer wall of the fixing rod.
[0006] As a further improvement to the above solution, four fixing rods are provided, which are symmetrically arranged around the center of the fixing column, and four springs are provided, which are symmetrically arranged around the center of the rubber ring.
[0007] The above technical solution involves rotating the handle to drive the threaded rod. A slider is fixedly connected to one end of the threaded rod, rotating within a support block via an inner groove. The support block provides support for the threaded rod, which is threadedly connected to the fixed block, causing the rubber ring to slide. The rubber ring presses against the inner wall of the outer shell, squeezing the mannan liquid inside. This compression compresses the rubber ring. When the rubber ring moves downwards, the spring is compressed, allowing the mannan liquid to flow out through its surface. When the threaded rod stops rotating, the spring's elasticity re-engages the rubber ring with the fixed post, preventing further outflow. This precise control of the sample volume reduces human error, ensuring high consistency in results for each experiment. It also protects the mannan liquid inside the outer shell from contamination by other substances, resulting in more accurate test data.
[0008] As a further improvement to the above solution, a feed inlet is provided at the top of the fixed block, and a connecting rod is fixedly connected inside the fixed block.
[0009] As a further improvement to the above solution, a limit block is fixedly connected to the end of the connecting rod away from the feed inlet, a spring is provided in contact with the outer wall of the connecting rod, and a rubber ring is slidably connected to the outer wall of the connecting rod.
[0010] The above technical solution first dilutes the mannan into a liquid. The liquid then enters through the feed inlet, applying pressure to the second rubber ring, which compresses the first spring. The second rubber ring slides on the outer wall of the connecting rod, reducing the contact between the mannan liquid and air, thus ensuring the purity of the mannan liquid and making the test data more accurate.
[0011] As a further improvement to the above solution, the fixing block has an inner groove, the top of the fixing block has a ventilation groove, the top of the fixing block has a slot, and the top of the rubber ring has a slot.
[0012] As a further improvement to the above solution, a rubber ring three is rotatably connected to the outer wall of the inner groove one. A vent hole is opened inside the rubber ring three. A fixing column one is fixedly connected to the top of the rubber ring three. A sliding rod is slidably connected inside the fixing column one. A support plate is fixedly connected to the outer wall of the fixing column one. A connecting plate is fixedly connected to the top of the sliding rod.
[0013] As a further improvement to the above solution, a locking rod is fixedly connected to the bottom of the end of the connecting plate away from the sliding rod. The locking rod is slidably connected inside the support plate. The locking rod contacts the outer wall of the locking groove. The locking rod is slidably connected to the outer wall of the support plate. A limit plate is fixedly connected to the outer wall of the locking rod. A spring is provided in contact with the outer wall of the locking rod.
[0014] Through the above technical solution, the vent hole is connected to the first vent hole, allowing air inside the shell to flow out. This keeps the pressure inside the shell constant when mannan liquid enters, thus reducing the contact between the mannan liquid and air. When the shell is full, the connecting plate is rotated again, causing the locking rod to re-engage with the outer wall of the slot. Spring 2 provides pressure to the limiting plate, fixing the limiting plate and the locking rod to prevent the locking rod from disengaging. At the same time, the vent hole and the first vent hole are misaligned, and the rubber ring 3 re-blocks the first vent hole.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes a rotating handle to drive a threaded rod. A slider is fixedly connected to one end of the threaded rod, rotating within a support block via an inner groove. The support block provides support for the threaded rod, which is threadedly connected to a fixed block. This causes a rubber ring to slide, squeezing the mannan liquid inside the outer shell against the inner wall. The compression of the mannan liquid further compresses the rubber ring. As the rubber ring moves downwards, the spring is compressed, allowing the mannan liquid to flow out through its surface. When the threaded rod stops rotating, the spring's elasticity re-engages the rubber ring with the fixed post, preventing further outflow of the mannan liquid. This precise control of the sample volume reduces human error, ensuring high consistency in experimental results. It also protects the mannan liquid inside the outer shell from contamination by other substances, resulting in more accurate test data.
[0017] This invention first dilutes mannan into a liquid, which then enters through the inlet. The liquid applies pressure to the second rubber ring, compressing the first spring. The second rubber ring slides against the outer wall of the connecting rod. This process reduces the contact between the mannan liquid and air, ensuring the purity of the mannan liquid and resulting in more accurate test data. Attached Figure Description

[0030] Please combine Figure 1-8 This embodiment discloses a precise quantitative sampler for mannan detection, comprising a shell 1, a rubber ring 2 slidably connected to the inner wall of the shell 1, a fixing block 3 fixedly connected to the inner wall of the rubber ring 2, a threaded rod 4 threadedly connected to the fixing block 3, a handle 5 fixedly connected to the top of the threaded rod 4, a slider 6 fixedly connected to the end of the threaded rod 4 away from the handle 5, a support block 7 fixedly connected to the inner wall of the shell 1, an inner groove 8 opened inside the support block 7, the slider 6 rotatably connected to the outer wall of the inner groove 8, a fixing post 9 fixedly connected to the inner wall of the shell 1, a fixing rod 10 fixedly connected inside the fixing post 9, a limit block 11 fixedly connected to the end of the fixing rod 10 away from the fixing post 9, a spring 12 contacting the outer wall of the fixing rod 10, and a rubber ring 13 slidably connected to the outer wall of the fixing rod 10.
[0031] There are four fixing rods 10, which are symmetrically arranged around the center of the fixing post 9. There are also four springs 12, which are symmetrically arranged around the center of the rubber ring 13.
[0032] The top of the fixed block 3 is connected to the feed inlet 14, and the fixed block 3 is fixedly connected to the connecting rod 15.
[0033] A limit block 16 is fixedly connected to the end of the connecting rod 15 away from the feed port 14. A spring 17 is provided in contact with the outer wall of the connecting rod 15. A rubber ring 18 is slidably connected to the outer wall of the connecting rod 15.
[0034] The fixing block 3 has an inner groove 19 inside, a ventilation groove 20 on the top of the fixing block 3, a slot 21 on the top of the fixing block 3, and a slot 22 on the top of the rubber ring 2.
[0035] A rubber ring 23 is rotatably connected to the outer wall of the inner groove 19. A vent hole 24 is opened inside the rubber ring 23. A fixing post 25 is fixedly connected to the top of the rubber ring 23. A sliding rod 26 is slidably connected inside the fixing post 25. A support plate 27 is fixedly connected to the outer wall of the fixing post 25. A connecting plate 28 is fixedly connected to the top of the sliding rod 26.
[0036] A locking rod 29 is fixedly connected to the bottom of the end of the connecting plate 28 away from the sliding rod 26. The locking rod 29 is slidably connected inside the support plate 27. The locking rod 29 is in contact with the outer wall of the slot 21. The locking rod 29 is slidably connected to the outer wall of the support plate 27. A limit plate 30 is fixedly connected to the outer wall of the locking rod 29. A spring 31 is in contact with the outer wall of the locking rod 29.
[0037] The implementation principle of a precise quantitative sampler for mannan detection in this embodiment is as follows: First, the mannan is diluted into a liquid. The liquid then enters through the inlet 14, applying pressure to the rubber ring 18, thus compressing the spring 17. The rubber ring 18 slides on the outer wall of the connecting rod 15, reducing contact between the mannan liquid and air, thereby ensuring the purity of the mannan liquid and making the detection data more accurate. Simultaneously, when the mannan liquid enters the outer shell 1, since the internal air pressure is the same as the external air pressure, injecting the mannan liquid may cause it to flow out from below. At this time, by pulling the connecting plate 28, the connecting rod... Plate 28 simultaneously drives sliding rod 26 and locking rod 29 to slide. As locking rod 29 disengages from slot 21, spring 31 is compressed. Since locking rod 29 slides inside support plate 27, rotating connecting plate 28 causes fixed post 25 to rotate via support plate 27. Simultaneously, fixed post 25 is fixed to rubber ring 23, causing rubber ring 23 to rotate. When locking rod 29 re-engages on the outer wall of slot 22, vent hole 24 connects with vent hole 32, allowing air inside shell 1 to flow out. This keeps the pressure inside shell 1 constant when mannan liquid enters, reducing contact between mannan liquid and air. After the interior is filled, rotate the connecting plate 28 again to re-engage the locking rod 29 into the outer wall of the slot 21. Spring 2 31 provides pressure to the limiting plate 30, fixing the limiting plate 30 to the locking rod 29 and preventing it from disengaging. At the same time, the vent 24 and the vent 1 32 are misaligned, and the rubber ring 3 23 re-blocks the vent 1 32. Now, by rotating the handle 5, the threaded rod 4 is rotated. A slider 6 is fixedly connected to one end of the threaded rod 4. The slider 6 rotates inside the support block 7 through the inner groove 8, while the support block 7 provides support for the threaded rod 4. The threaded rod 4 is threadedly connected to the fixing block 3, thereby causing the rubber ring 2 to slide. The rubber ring 2 slides along the inner wall of the outer shell 1. The wall squeezes the mannan liquid inside the outer shell 1. As the mannan liquid is squeezed, the rubber ring 13 is also squeezed. When the rubber ring 13 moves downward, the spring 12 is compressed, causing the mannan liquid to flow out through the surface of the rubber ring 13. When the threaded rod 4 stops rotating, the spring 12 uses its elasticity to re-adhere the rubber ring 13 to the fixed post 9, thereby preventing the mannan liquid from flowing out. This allows for precise control of the amount taken. By precisely controlling the amount taken, human error can be reduced, ensuring high consistency of results in each experiment. It also protects the mannan liquid inside the outer shell 1 from contamination by other substances, thus making the detection data more accurate.
[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
