Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to a sampler for chemical reagent production. Background Technology

[0002] When producing chemical reagents, it is necessary to use a sampler to test the quality of the chemical reagents. However, the existing samplers used in chemical reagent production are generally not capable of quantitative delivery.

[0003] Existing technology CN218381863U discloses a sampler for chemical reagent production, including a sampler body and a quantitative component. The quantitative component is disposed on the sampler body and includes a pull rod, a fixed shell, a sliding rod, a limiting plate, a push spring, a rotating rod, a positioning block, a rotating plate, and two rubber blocks. The pull rod is slidably connected to the body and has multiple positioning grooves. The fixed shell is fixedly connected to the body and located on one side of the pull rod. The sliding rod is slidably connected to the fixed shell and has a stabilizing groove. The limiting plate is fixedly connected to the surface of the sliding rod. The push spring is sleeved on the surface of the sliding rod and located between the limiting plate and the fixed shell. The rotating rod is rotatably connected to the sliding rod. The positioning block is fixedly connected to the rotating rod and located between the sliding rod and the pull rod. The rotating plate is fixedly connected to the end of the rotating rod away from the positioning block. The two rubber blocks are fixedly connected to the sliding rod. The positioning bar is fixed to one side of the rotating plate and slidably connected to the stabilizing groove. When extracting a sample, the pull rod is rotated to align multiple positioning grooves with the positioning blocks. The rotating rod is then rotated to make the inclined surface of the positioning block face downwards, and it is fixed by the action of two rubber blocks and the stabilizing groove. The pull rod is pulled to extract the sample. When the positioning groove reaches the position of the positioning block, the sliding rod pushes the positioning block under the action of the push spring and the limiting block, so that the positioning block is stuck in the positioning groove, indicating that the first quantitative sample has been extracted. If the pull rod is pulled again, the positioning block is squeezed out of the positioning groove by the action of the inclined surface of the positioning block, so that sampling can continue. When injecting the sample, the inclined surface of the positioning block is made to face upwards by rotating the rod, rotating plate and two rubber blocks, and the pull rod is pushed to inject the sample. Each time a positioning groove passes the positioning block, it means that one standard unit of sample has been injected, thus achieving the effect of quantitative injection of samples.

[0004] However, when using the existing samplers for chemical reagent production, the positioning block is always in direct friction with the sliding rod on one side. With long-term use, the pull rod is prone to wear and misalignment, which leads to a large deviation in the sampler's measurement function and reduces the reliability of the test results. Utility Model Content

[0005] The purpose of this invention is to provide a sampler for chemical reagent production, which aims to solve the problem that in existing chemical reagent production samplers, the positioning block always directly rubs against the sliding rod on one side during use, which easily leads to wear and misalignment of the pull rod after long-term use, resulting in a large deviation in the sampler's metering function and reducing the reliability of the test results.

[0006] To achieve the above objectives, this utility model provides a sampler for chemical reagent production, comprising a sampler body and a quantitative sampling mechanism. The quantitative sampling mechanism includes a push-pull rod, two mating components, and two quantitative components. The push-pull rod is fixedly and slidably connected within the sampler body and is marked. The two mating components are mirror images of each other on both sides of the push-pull rod. Each mating component includes a connecting piece and a mating strip. The connecting piece is fixedly connected to the push-pull rod and slidably connected within the sampler body. The mating strip is naturally and slidably connected to the sampler and fixedly connected to the side of the connecting piece away from the push-pull rod, and is provided with multiple unit slots. The two quantitative components are disposed on the sampler body and are respectively located on one side of the two mating components.

[0007] The quantitative component includes two connectors, a mounting shell, and a functional component. The two connectors are mirror images of the sampler body, the mounting shell is disposed between the two connectors, and the functional component is disposed inside the mounting shell.

[0008] The functional component includes a ball bearing and a reset component. The ball bearing is slidably connected within the mounting housing, and the reset component is disposed within the mounting housing.

[0009] The reset component includes a reset block and a spring. The reset block is slidably connected to the ball bearing and is slidably connected inside the mounting housing. The two ends of the spring are fixedly connected to the reset block and the mounting housing, respectively, and are located inside the mounting housing.

[0010] The connector includes a connecting frame and two connecting bolts. The connecting frame is fixedly connected to the sampler body and is located on one side of the mounting shell. The two connecting bolts are threaded into the mounting shell and pass through the connecting frame.

[0011] This utility model discloses a sampler for chemical reagent production. When using the sampler, pulling the push-pull rod causes two connecting pieces to move two mating strips. With the cooperation of the two quantitative components, each time a unit of sample is extracted, the two quantitative components engage with the two mating strips, causing the push-pull rod to stop, thus alerting the operator. Simultaneously, the number of sample units extracted can be easily checked according to the markings on the push-pull rod surface. Because the two quantitative components are mirror-mounted on both sides of the push-pull rod, the force is evenly distributed, making it difficult to deviate. This avoids the problem in existing chemical reagent production samplers where the positioning block constantly rubs directly against the sliding rod on one side, leading to wear and deflection of the pull-pull rod over long-term use, resulting in significant deviations in the sampler's measurement function and reduced reliability of the test results. This design extends the lifespan of the device and ensures accurate sampling. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 ,in Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2This is a schematic diagram of the structure of the quantitative component of this utility model; Figure 3 yes Figure 1 A magnified view of a section at point A in the middle; Figure 4 yes Figure 2 A cross-sectional view along line BB.

[0020] This utility model provides a sampler for chemical reagent production: it includes a sampler body 1 and a quantitative sampling mechanism. The quantitative sampling mechanism includes a push-pull rod 2, two mating components 3, and two quantitative components 4. The mating components 3 include a connecting piece 5 and a mating strip 6. The quantitative components 4 include two connecting parts 7, a mounting shell 8, and a functional component 9. The functional component 9 includes a ball bearing 10 and a reset component 11. The reset component 11 includes a reset block 12 and a spring 13. The connecting parts 7 include a connecting frame 14 and two connecting bolts 15. The aforementioned solution solves the problem that in existing chemical reagent production samplers, the positioning block always directly rubs against the sliding rod on one side during use, which easily leads to wear and skew of the pull-pull rod after long-term use, resulting in a large deviation in the metering function of the sampler and reducing the reliability of the test results.

[0021] In this specific embodiment, the push-pull rod 2 is fixedly and slidably connected to the sampler body 1 and is marked. Two mating components 3 are mirror-mounted on both sides of the push-pull rod 2. The connecting piece 5 is fixedly connected to the push-pull rod 2 and slidably connected to the sampler body 1. The mating strip 6 is naturally and slidably connected to the sampler and fixedly connected to the side of the connecting piece 5 away from the push-pull rod 2, and is provided with multiple unit slots 16. Two quantitative components 4 are disposed on the sampler body 1 and are respectively located on one side of the two mating components 3. When using the sampler, pull the push-pull rod 2. The push-pull rod 2 moves the two mating strips 6 through the two connecting pieces 5. With the cooperation of the two quantitative components 4, each time a unit of sample is extracted, the two quantitative components 4 will cooperate with the two mating strips 6 to stop the push-pull rod 2, prompting the operator. At the same time, the number of sample units extracted can be easily checked according to the markings on the surface of the push-pull rod 2. Because the two quantitative components 4 are mirrored on both sides of the push-pull rod 2, the push-pull rod 2 is evenly stressed and difficult to deviate.

[0022] The two connecting pieces 7 are mirror images of the sampler body 1, the mounting shell 8 is positioned between the two connecting pieces 7, and the functional component 9 is located within the mounting shell 8. When the push-pull rod 2 moves, it drives the two mating strips 6 to move via the two connecting pieces 5. When the unit slots 16 on the two mating strips 6 reach the mounting shell 8, the functional component 9 enters the unit slots 16, causing the push-pull rod 2 to stop, indicating to the user that one unit of sample has been drawn or injected. If the push-pull rod 2 continues to move, the force is increased, and the two functional components 9 are squeezed out of the unit slots 16 on the two mating strips 6. At the same time, the markings on the push-pull rod 2 can be observed to directly determine how many units of sample have been drawn or injected. If the functional component 9 needs to be repaired, it can be disassembled via the two connecting pieces 7.

[0023] Secondly, the ball bearing 10 is slidably connected to the mounting shell 8, and the reset member 11 is disposed in the mounting shell 8. When the unit groove 16 on the mating strip 6 is at the same height as the ball bearing 10, the ball bearing 10 is in a compressed state. Under the action of the reset member 11, it pops out of the mounting shell 8 and gets stuck in the unit groove 16. With the cooperation of the two balls bearing 10 and the two mating strips 6, the push-pull rod 2 stops, thereby indicating to the operator that a unit of sample has been drawn or injected.

[0024] Meanwhile, the reset block 12 is slidably connected to the ball bearing 10 and slidably connected within the mounting shell 8. The two ends of the spring 13 are fixedly connected to the reset block 12 and the mounting shell 8 respectively, and are located within the mounting shell 8. When the ball bearing 10 is squeezed, it retracts into the mounting shell 8 and pushes the reset block 12 to squeeze the spring 13. When the ball bearing 10 is at the same height as the unit groove 16, the ball bearing 10 is no longer compressed, the spring 13 resets, pushes the reset block 12, and thus the ball bearing 10 pops out of the mounting shell 8 and pushes into the unit groove 16.

[0025] Finally, the connecting frame 14 is fixedly connected to the sampler body 1 and is located on one side of the mounting shell 8. The two connecting bolts 15 are threaded into the mounting shell 8 and pass through the connecting frame 14. When it is necessary to disassemble the mounting shell 8 and the functional component 9, unscrew the four connecting bolts 15 and remove the mounting shell 8 from between the two connecting frames 14.

[0026] When using the sampler, pulling the push-pull rod 2 causes it to move via the two connecting pieces 5, which in turn move the two mating strips 6. With the cooperation of the two quantitative components 4, each time a unit of sample is extracted, the two quantitative components 4 engage with the two mating strips 6, causing the push-pull rod 2 to pause, thus alerting the operator. Simultaneously, the number of sample units extracted can be easily checked using the markings on the surface of the push-pull rod 2. Because the two quantitative components 4 are mirror-mounted on both sides of the push-pull rod 2, the force on the push-pull rod 2 is even, making it difficult to deviate. As the push-pull rod 2 moves, it is controlled by the two connecting pieces... 5. The two mating strips 6 are moved. When the unit slots 16 on the two mating strips 6 reach the mounting shell 8, the functional component 9 enters the unit slot 16, causing the push-pull rod 2 to stop, indicating to the user that one unit of sample has been drawn or injected. If the push-pull rod 2 is moved further, the force is increased, and the two functional components 9 are squeezed out of the unit slots 16 on the two mating strips 6. At the same time, the markings on the push-pull rod 2 can be observed to directly determine how many units of sample have been drawn or injected. If the functional component 9 needs to be repaired, it can be disassembled through the two connecting parts 7. The mating strips When the unit groove 16 on the 6 is at the same height as the ball 10, the ball 10, which is in a compressed state, pops out of the mounting shell 8 under the action of the reset member 11 and gets stuck in the unit groove 16. With the cooperation of the two balls 10 and the two mating strips 6, the push-pull rod 2 stops, indicating to the operator that a unit of sample has been drawn or injected. When the ball 10 is squeezed, it retracts into the mounting shell 8 and pushes the reset block 12 to squeeze the spring 13. When the ball 10 is at the same height as the unit groove 16, the ball 10 is no longer compressed, and the spring 13 resets. The reset block 12 is pushed, causing the ball bearing 10 to pop out of the mounting shell 8 and into the unit groove 16. When it is necessary to disassemble the mounting shell 8 and the functional component 9, the four connecting bolts 15 are unscrewed, and the mounting shell 8 can be removed from between the two connecting frames 14. This avoids the problem that in existing chemical reagent production samplers, the positioning block always rubs directly against the sliding rod on one side, which can easily lead to wear and misalignment of the pull rod after long-term use, resulting in a large deviation in the metering function of the sampler and reducing the reliability of the test results. This method extends the life of the device and ensures accurate sampling.
