Abstract
Description
Technical Field
[0001] This utility model relates to the field of activation instrument technology, and in particular to an analytical tube activation instrument. Background Technology
[0002] In fields such as environmental monitoring, chemical analysis, and food safety, adsorption tubes, as core components for sample collection and pretreatment, are commonly used to enrich target substances such as volatile organic compounds and harmful gases in the air. Activation and desorption of used adsorption tubes are crucial for their reuse and ensuring detection accuracy. During activation and desorption, the adsorption tube needs to be uniformly heated to desorb the target substance. Simultaneously, the adsorption tube must remain stable and fixed during heating to avoid affecting the desorption effect due to positional displacement or poor contact. It must also be easy for operators to quickly install and disassemble to improve work efficiency.
[0003] Existing clamping and fixing structures often use simple snap-fit or manual pressing methods, which makes it difficult to ensure a tight fit between the adsorption tube and the heating component. This can easily lead to uneven heating, resulting in low or incomplete desorption efficiency. Furthermore, the position of the desorption tube is difficult to adjust after it is fixed.

[0030] Example 1
[0031] like Figure 1-5 As shown, the present invention proposes a tube activator for activating and activating multiple adsorption tubes 7, comprising an activator body 1, a heating unit 2, a clamping unit 3, a pressing component 5, and a pushing mechanism.
[0032] Heating unit 2 is installed on the body 1 of the activator for heating and heat preservation of adsorption tube 7; clamping unit 3 is installed on heating unit 2 and abuts against adsorption tube 7 for fixing adsorption tube 7; pressing component 5 is installed on heating unit 2 and abuts against clamping unit 3 for pushing clamping unit 3 to press adsorption tube 7; pushing mechanism is slidably installed on heating unit 2 for pushing clamping unit 3 to separate from adsorption tube 7.
[0033] The activator body 1 includes a control box 101, gas pipes 102, and connecting hoses 103. Multiple gas pipes 102 are mounted on the control box 101 and located on both sides of the heating unit 2. Multiple connecting hoses 103 are connected to their respective gas pipes 102, with each hose connecting to one adsorption tube 7. The heating unit 2 includes a housing 201, two sealing plates 202, and a heating plate 203. The housing 201 has a placement chamber 2011 for accommodating the adsorption tube 7. The housing 201 is mounted on the control box 101. The two sealing plates 202 are located on both sides of the housing 201. The heating plate 203 is located inside the placement chamber 2011 and contacts the adsorption tube 7 placed inside the chamber to heat it. The sealing plates 202 have guide grooves 2021 for easy insertion of the adsorption tube 7.
[0034] In this embodiment, when installing the adsorption tube 7, first rotate the clamping assembly 5 to allow the pressure plate 301 to move upward. Then, pry up the connecting plate 4 by pushing the assembly 6. The connecting plate 4 drives the clamping unit 3 to move upward, thereby allowing the pressure plate 301 to separate from the heating plate 203. This allows the adsorption tube 7 to be inserted from the sealing plate 202 into the placement chamber 2011, with the adsorption tube 7 positioned on the heating plate 203. Then, release the pushing assembly 6, allowing the pressure plate 301 to press onto the adsorption tube 7 for initial fixation. At this point, because the pressure is not high, it is easy to move the adsorption tube 7 and adjust its position. To facilitate the connection between the adsorption tube 7 and the connecting hose 103, after the position of the adsorption tube 7 is adjusted, the adsorption tube 7 rests against the clamping unit 3, so that the pressure plate 301 firmly presses the adsorption tube 7 onto the heating plate 203, thereby fixing the adsorption tube 7 and making the adsorption tube 7 fit more closely with the heating plate 203 and the pressure plate 301. Both the heating plate 203 and the pressure plate 301 are equipped with heating elements, so that the adsorption tube 7 can be heated evenly. After the adsorption tube 7 is fixed by the pressure plate 301, it is more stable when connecting the hose 103, and there is no need to hold the other end of the adsorption tube 7 by hand, which can prevent the adsorption tube 7 from sliding.
[0035] Example 2
[0036] like Figure 1-5As shown, the present invention proposes an analytical tube activation instrument. Compared with Embodiment 1, the clamping unit 3 in this embodiment includes a pressure plate 301, multiple sliding columns 302 and multiple elastic elements 303. The pressure plate 301 is slidably disposed in the placement chamber 2011 for contacting the adsorption tube 7. The multiple sliding columns 302 are all disposed on the pressure plate 301 and slidably connected to the housing 201. The multiple elastic elements 303 are respectively disposed on the outer periphery of the multiple sliding columns 302, and their two ends are respectively connected to the housing 201 and the pressure plate 301.
[0037] The clamping assembly 5 includes a handwheel 501 and a threaded rod 502. The threaded rod 502 is threadedly connected to the housing 201, and its lower end is used to abut against the pressure plate 301. The handwheel 501 is set on the threaded rod 502. By rotating the handwheel 501, the threaded rod 502 is driven to move axially. The clamping assembly 5 can abut against the clamping unit 3 to ensure the reliability of the connection.
[0038] The pushing mechanism includes a connecting plate 4 and a pushing assembly 6. The connecting plate 4 is mounted on multiple sliding columns 302. The pushing assembly 6 is movably mounted on the housing 201 and slidably connected to the connecting plate 4. The connecting plate 4 has a rotating groove 401, through which a threaded rod 502 passes and is clearance-fitted. The pushing assembly 6 includes a support frame 601, a pry bar 602, a handle 603, and a sliding roller 604. The support frame 601 is mounted on the housing 201. The pry bar 602 is rotatably mounted on the support frame 601. The pry bar 602 has a V-shaped structure with an obtuse angle. The handle 603 is located at one end of the pry bar 602. The sliding roller 604 is rotatably located at the other end of the pry bar 602 and slidably connected to the connecting plate 4. The pushing assembly 6 can pry up the connecting plate 4, which in turn can drive the clamping unit 3 to move upward, causing the clamping unit 3 to separate from the adsorption tube 7, thereby allowing the adsorption tube 7 to be extracted.
[0039] In this embodiment, when it is necessary to insert the adsorption tube 7 into the housing 201 or pull out the adsorption tube 7, firstly rotate the handwheel 501, so that the handwheel 501 drives the threaded rod 502 to rotate, and the threaded rod 502 moves upward, thereby separating the threaded rod 502 from the pressure plate 301, so that the pressure plate 301 has space to move upward; at this time, press down the handle 603, the handle 603 drives the pry bar 602 to flip, the pry bar 602 drives the sliding roller 604 to move, so that the sliding roller 604 is raised, thereby pushing the connecting plate 4 to move upward. The sliding roller 604 can reduce the friction between the pry bar 602 and the connecting plate 4, making it easier to drive the connecting plate 4 to move upward. The connecting plate 4 drives the sliding column 302 to move upward, so that the sliding column 302 drives the pressure plate 301 to move upward, thereby allowing the pressure plate 301 to separate from the heating plate 203, so that the adsorption tube 7 can be inserted into the housing 201 and then pulled out from the housing 201.
[0040] After the adsorption tube 7 is placed, release the handle 603, causing the pry bar 602 to lose its support. The elastic element 303 pushes the pressure plate 301 downward, which in turn causes the sliding column 302 to move downward. The sliding column 302 then causes the connecting plate 4 to move downward, thereby resetting the pushing assembly 6. The pressure plate 301 can then press down on the adsorption tube 7 to initially fix it. By rotating the threaded rod 502, the threaded rod 502 is pressed against the pressure plate 301, which securely fixes the pressure plate 301 and prevents it from moving upward. This allows the support frame 601 to press down on the adsorption tube 7 and fix it in place. Both the heating plate 203 and the pressure plate 301 are provided with matching grooves. The adsorption tube 7 is embedded in the matching grooves, allowing it to fit snugly against the heating plate 203 and the pressure plate 301.
[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
