Description

Technical Field

[0001] This utility model relates to the field of sampling mechanism technology, specifically to a sampling mechanism and a rapid benzene detection device. Background Technology

[0002] Benzene is an aromatic hydrocarbon that is flammable, volatile, and colorless liquid with a characteristic aromatic odor at room temperature. Benzene is highly toxic. It is the simplest aromatic hydrocarbon, sparingly soluble in water but readily soluble in organic solvents, and can itself be used as an organic solvent.

[0003] In existing technologies, after pure benzene is produced, it is usually necessary to take samples by a sampling agency and then use a rapid detection device for testing.

[0004] However, traditional sampling mechanisms are all of fixed length. When staff take samples of benzene at different depths in the container, they usually need to use multiple sampling tubes of different lengths to take multiple samples, which is inconvenient for staff to use. Therefore, this utility model proposes a sampling mechanism and a rapid benzene detection device to solve the above problems. Utility Model Content

The slider has a square plate structure and can slide along a square groove in the sampling cylinder. External threaded tubes and internal threaded tubes are fixedly connected to both ends of the sampling cylinder, respectively.

[0011] Preferably, a miniature squeeze bottle is fixedly connected to the mounting head, and one end of the miniature squeeze bottle is engaged in a mounting groove opened on the moving rod. The mounting groove has a circular groove structure.

[0015] A rapid benzene detection device includes the aforementioned sampling mechanism.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention presents a sampling mechanism and a rapid benzene detection device. By installing the sampling section on the adjustment section, then sequentially installing other sampling sections, and finally installing the mounting section, the length of the sampling mechanism can be extended. Rotating the rotating head causes the screw to rotate along the threaded end of the holding tube. The round rod pushes the moving rod, aligning the mounting groove on the moving rod with the round groove on the sampling cylinder, thus restoring the compressed micro-squeezing bottle to its original shape. The micro-squeezing bottle absorbs benzene, completing the sampling. This device can adapt to sampling benzene at different depths and can absorb benzene at different depths in the container through the micro-squeezing bottles on the sampling sections at different ends. Sampling at different depths can be completed in one go, eliminating the need for multiple sampling tubes of different lengths, making it convenient for practical use. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] Please see Figures 1 to 9 This utility model provides a technical solution: a sampling mechanism, comprising: an adjustment part 1, a sampling part 2, and an installation part 3. The installation part 3 includes a thrust spring 25, a push plate 26, and a limiting block 27; the sampling part 2 includes a sampling cylinder 10, an externally threaded tube 8, an internally threaded tube 9, and a moving rod 11, and an installation head 17 is installed on the sampling part 2, with a miniature squeezing bottle 15 disposed on the installation head 17; the adjustment part 1 includes a rotating head 4, a screw 5, a round rod 6, and a holding tube 7. A rapid benzene detection device includes the aforementioned sampling mechanism.

[0031] In practical use, several sampling units 2 can be installed on the adjustment unit 1, which can extend the sampling mechanism, making it convenient for staff to use and highly adaptable.

[0032] Example 2

[0033] Based on Embodiment 1, a screw 5 is provided for ease of use. The screw 5 is fixedly connected to a round rod 6. The other end of the round rod 6 is in contact with a moving rod 11. A slider 13 is fixedly connected to the side of the moving rod 11. The slider 13 has a square plate-like structure and can slide along a square groove 12 opened inside the sampling cylinder 10. An external threaded tube 8 and an internal threaded tube 9 are fixedly connected to both ends of the sampling cylinder 10, respectively. The slider 13 is fixedly connected to the side of the moving rod 11 and is locked in the groove 12 opened inside the sampling cylinder 10. This limits the movement of the moving rod 11 and prevents it from falling. The external threaded tube 8 can be threadedly connected to the internal threaded tube 9.

[0034] The sampling unit 2 includes a sampling cylinder 10. An installation head 17 is fitted into a circular groove 21 on the sampling cylinder 10. A locking block 19 fixedly connected to the side of the installation head 17 is fitted into a convex groove 22 on the sampling cylinder 10. The locking block 19 has a convex plate-like structure. A friction pad 20 is fixedly connected to the side of the locking block 19. The installation head 17 is fitted into the circular groove 21, and the locking block 19 fixedly connected to the installation head 17 acts as a positioning block to fit into the groove 22 on the sampling cylinder 10, which is convenient for personnel to install. The square plate-like friction pad 20 fixedly connected to the side of the locking block 19 can improve the stability of the locking block 19 when it is fitted into the groove 22 and prevent it from falling off.

[0035] The adjustment unit 1 includes a rotating head 4, one end of which is fixedly connected to a screw 5. The screw 5 is threadedly connected to a threaded part inside the gripping tube 7. One end of the gripping tube 7 is fixedly connected to an external threaded tube 8. By threading the external threaded tube 8 fixedly connected to the sampling cylinder 10 to the internal threaded tube 9 fixedly connected to the gripping tube 7, and threading the internal threaded tube 9 on the other end of the sampling cylinder 10 to the external threaded tube 8 on another sampling cylinder 10, and so on, several sampling units 2 are assembled together and installed on the adjustment unit 1. The external threaded tube 8 fixedly connected to the mounting cylinder 23 is threadedly connected to the internal threaded tube 9 on the sampling cylinder 10, thus completing the installation. This method can extend the length of the sampling mechanism, making it easier for personnel to use and highly adaptable.

[0036] A miniature squeeze bottle 15 is fixedly connected to the mounting head 17. One end of the miniature squeeze bottle 15 is inserted into the mounting groove 14 on the moving rod 11. The mounting groove 14 is a circular groove structure. The operator places the device into a tank containing pure benzene liquid, rotates the rotating head 4 to make the screw 5 rotate along the threaded end of the holding tube 7, and makes the round rod 6 push the moving rod 11. The moving rod 11 and the slider 13 move along the sliding groove 12 in the sampling cylinder 10, and the moving rod 11 pushes the push rod 18, making the push plate 26 and the limiting block 27 slide along the limiting groove 16, and compressing the thrust spring 25. This makes the mounting groove 14 on the moving rod 11 correspond to the circular groove 21 on the sampling cylinder 10, so that the miniature squeeze bottle 15 in the compressed state returns to its original state. The nozzle on the miniature squeeze bottle 15 absorbs the pure benzene in the tank to complete the sampling work. Through the multi-segment sampling section 2 on the device, pure benzene at different depths in the tank can be sampled at one time, which is convenient for personnel to use.

[0037] Example 3

[0038] Based on Embodiment 2, an installation part 3 is provided to improve the practicality of the device. The installation part 3 includes an installation cylinder 23, on which an installation mechanism 24 is threadedly connected. A thrust spring 25 and a push plate 26 are provided inside the installation cylinder 23. The push plate 26 has a circular push-shaped structure and is fixedly connected to a push rod 18. The push rod 18 contacts the moving rod 11. The thrust spring 25 only contacts the push plate 26 and the installation mechanism 24. The installation mechanism 24 can be rotated to remove it from the installation cylinder 23, and the thrust spring 25 inside the installation cylinder 23 can be removed and replaced, which is convenient for personnel to use.

[0039] A limiting groove 16 is provided inside the mounting cylinder 23. An external threaded tube 8 is fixedly connected to the mounting cylinder 23. The limiting groove 16 has a "convex" groove structure. A limiting block 27 with a "convex" plate shape is provided inside the limiting groove 16. The limiting block 27 is fixedly connected to the push plate 26 and can slide along the limiting groove 16. In the initial state, the screw 5 fixedly connected to the rotating head 4 is not fully screwed into the threaded part on the holding tube 7, and part of the screw 5 is exposed. At this time, the push plate 26 and the push rod 18 are pushed by the thrust spring 25. The push rod 18 contacts the moving rod 11 and squeezes the moving rod 11, so that the mounting groove 14 opened on the moving rod 11 does not correspond to the circular groove 21 opened on the sampling cylinder 10. In this way, the micro-squeezing bottle 15 is in a compressed state.

[0040] Working principle: In actual use, the sampling part 2 is installed on the adjustment part 1, and then other sampling parts 2 are installed in sequence, and finally the installation part 3 is installed. This can extend the length of the sampling mechanism. Rotating the rotating head 4 causes the screw 5 to rotate along the threaded end of the holding tube 7. The round rod 6 pushes the moving rod 11, so that the installation groove 14 on the moving rod 11 corresponds to the round groove 21 on the sampling tube 10, so that the miniature squeeze bottle 15 in the compressed state returns to its original shape. The miniature squeeze bottle 15 absorbs pure benzene to complete the sampling. This device can adapt to the sampling of pure benzene at different depths. Moreover, it can absorb pure benzene at different depths in the tank through the miniature squeeze bottle 15 on the sampling part 2 at different ends. The sampling work at different depths can be completed in one go, without the need to use sampling tubes of different lengths for sampling multiple times, which is convenient for personnel to use.
