Description
An integrated device for monitoring gaseous molecular pollutants Technical Field
[0001] This utility model relates to the field of gaseous molecular pollutant monitoring technology, specifically an integrated gaseous molecular pollutant monitoring device. Background Technology
[0002] Gaseous molecular contaminants (AMCs) are a major concern in high-tech manufacturing, particularly in the microelectronics industry. Organic pollutants can adversely affect production equipment, ultimately leading to additional costs. A pollution-free production environment is not just a dream but a reality, requiring strict control over raw materials and air filtration systems throughout the manufacturing process. Permanent monitoring of AMCs can help stabilize production and extend the lifespan of filtration devices. AMCs in cleanroom environments originate internally from releases from building materials, equipment and materials, chemical releases during processes such as etching and photolithography, personnel generation, pipeline leaks, and emissions during equipment maintenance and repair. Externally, they come from gaseous contaminants in the ambient air and from exhaust gases re-entered into the cleanroom. Excessive AMC levels can lead to serious consequences, such as wafer scrapping, production stoppages, and the need for re-cleaning the cleanroom. Therefore, integrated AMC monitoring devices have emerged on the market.
[0003] However, existing integrated gaseous molecular pollutant monitoring devices are equipped with casters at the bottom for easy movement. Ordinary casters have low shock absorption performance, while the internal parts of the integrated gaseous molecular pollutant monitoring device are quite delicate. This means that when the device is moved, the delicate internal parts are easily damaged by vibration, affecting the use of the integrated gaseous molecular pollutant monitoring device. Therefore, this does not meet the current requirements. To address this, we propose an integrated gaseous molecular pollutant monitoring device. Summary of the Invention
[0004] The purpose of this utility model is to provide an integrated gaseous molecular pollutant monitoring device to solve the problem mentioned in the background art that the integrated gaseous molecular pollutant monitoring device is equipped with casters at the bottom for easy movement. However, ordinary casters have low shock absorption performance, and the internal parts of the integrated gaseous molecular pollutant monitoring device are relatively delicate. As a result, when the integrated gaseous molecular pollutant monitoring device is moved, the delicate internal parts are easily damaged by vibration, which affects the use of the integrated gaseous molecular pollutant monitoring device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated gaseous molecular pollutant monitoring device, comprising a main body for the gaseous molecular pollutant monitoring device, characterized in that:
[0006] A fixed cylinder is fixedly installed inside the lower end of the main body of the gaseous molecular pollutant monitoring device. A hydraulic cylinder is fixedly installed at the upper end of the fixed cylinder. A lifting shaft is installed at the upper end of the hydraulic cylinder.

A pressing plate is installed at the lower end of the connecting ring. Oil passage holes are provided on the outside of both the rotating adjustment plate and the pressing plate. A connecting rod is fixedly installed at the lower end of the pressing plate.
[0007] A rotating adjustment bracket is fixedly installed on the upper end of the lifting shaft. An outer plate is fixedly installed on the upper end of the fixed cylinder. An adjustment hole is provided on the upper end of the outer plate. A limit pin is installed inside the adjustment hole through a slot.

[0012] Preferably, the upper end of the limiting plate is fixedly connected to the return spring, and the hydraulic cylinder is filled with hydraulic oil.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, by installing a rotating adjustment plate in conjunction with a lifting shaft and a rotating adjustment bracket, allows operators to easily adjust the position of the rotating adjustment plate and the external oil passage of the extrusion plate, thereby adjusting the cross-sectional area of the oil passing through the oil passage and thus achieving the purpose of adjusting the shock absorption strength of the device. This makes the device more convenient to use, enhances its effectiveness, reduces the difficulty of using the device, and allows operators to adjust the shock absorption strength of the device according to their needs, making the device more flexible.
[0015] 2. By installing a pressing plate, this utility model allows the universal wheel to push the pressing plate upwards via the connecting rod when the device vibrates during movement. This causes the connecting rod to press the hydraulic oil inside the hydraulic cylinder, which in turn allows the hydraulic oil to flow through the oil passage in the fixed cylinder. This enables the device to absorb vibrations, making its movement more stable and preventing damage to the precision parts inside the device under vibration. The installation of the outer plate and the limiting pin shaft facilitates the limiting of the rotation adjustment bracket, thereby limiting the position of the rotation adjustment plate and the external oil passage of the pressing plate, ensuring the stability of the device's vibration damping strength.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please refer to Figures 1-5. One embodiment of this utility model is provided: an integrated gaseous molecular pollutant monitoring device, comprising a main body 1 of the gaseous molecular pollutant monitoring device, characterized in that:
[0024] The fixed cylinder 3 is fixedly installed inside the lower end of the main body 1 of the gaseous molecular pollutant monitoring device. A hydraulic cylinder 18 is fixedly installed at the upper end of the fixed cylinder 3. A lifting shaft 10 is installed at the upper end of the hydraulic cylinder 18, and a rotating adjustment plate 11 is fixedly installed at the lower end of the lifting shaft 10. Installing the rotating adjustment plate 11, in conjunction with the lifting shaft 10 and the rotating adjustment bracket 4, allows the operator to easily adjust the position of the rotating adjustment plate 11 relative to the external oil passage 13 of the extrusion plate 12. This adjusts the cross-sectional area of the oil passing through the oil passage 13, thereby adjusting the device's vibration damping strength, making the device more convenient to use, enhancing its effectiveness, reducing the difficulty of operation, and facilitating operation according to needs. The damping strength of the adjustment device is improved, making the device more flexible. A connecting ring 17 is installed inside the lower end of the rotating adjustment plate 11, and a pressing plate 12 is installed at the lower end of the connecting ring 17. Both the rotating adjustment plate 11 and the pressing plate 12 are provided with oil passage holes 13. When the device vibrates during movement, the universal wheel 7 will push the pressing plate 12 upward through the connecting rod 15, so that the connecting rod 15 will squeeze the hydraulic oil inside the hydraulic cylinder 18, and then the hydraulic oil will flow through the oil passage holes 13 inside the fixed cylinder 3, so that the device can absorb shock and move more smoothly, and avoid damage to the precision parts inside the device under vibration. The connecting rod 15 is fixedly installed at the lower end of the pressing plate 12.
[0025] The rotating adjustment bracket 4 is fixedly installed on the upper end of the lifting shaft 10. The outer plate 8 is fixedly installed on the upper end of the fixed cylinder 3. The installation of the outer plate 8 and the limiting pin 5 can facilitate the limiting of the rotating adjustment bracket 4, thereby limiting the position of the rotating adjustment plate 11 and the oil through hole 13 on the outside of the extrusion plate 12, ensuring the stability of the device's shock absorption strength. The upper end of the outer plate 8 is provided with an adjustment hole 9. The limiting pin 5 is installed inside the adjustment hole 9 through a slot. The return spring 14 is installed on the outside of the hydraulic cylinder 18, and the limiting plate 16 is fixedly installed on the outside of the connecting rod 15.
[0026] Please refer to Figures 1, 2, 3, 4, and 5. A mounting plate 6 is installed at the lower end of the connecting rod 15, and the mounting plate 6 is fixedly connected to the connecting rod 15. A caster wheel 7 is installed at the lower end of the mounting plate 6, and the caster wheel 7 is connected to the mounting plate 6 by screws. A shielding door 2 is installed at the lower end of the front face of the main body 1 of the gaseous molecular pollutant monitoring device, and the shielding door 2 is connected to the main body 1 of the gaseous molecular pollutant monitoring device by a hinge. The lifting shaft 10 is longitudinally slidably connected to the hydraulic cylinder 18 and the fixed cylinder 3 through slots. The connecting ring 17 is rotatably connected to the rotating adjusting plate 11 and the extrusion plate 12 through slots. Installing the connecting ring 17 allows the rotating adjusting plate 11 and the extrusion plate 12 to connect, and ensures that the rotating adjusting plate 11 can rotate outside the extrusion plate 12, ensuring that the operator can easily adjust the position of the external oil passage hole 13 of the rotating adjusting plate 11 and the extrusion plate 12. The upper end of the limiting plate 16 is fixedly connected to the return spring 14. Hydraulic oil is installed inside the hydraulic cylinder 18.
[0027] Working principle: When the operator pushes this device, the caster wheel 7 contacts the ground. When the caster wheel 7 encounters uneven ground while rolling, it vibrates. This vibration is transmitted through the connecting rod 15, causing the return spring 14 to compress. Then, the pressure plate 12 compresses the hydraulic oil inside the hydraulic cylinder 18, forcing the hydraulic oil to flow through the oil passage 13. Due to the large amount of hydraulic oil, the pressure plate 12 encounters resistance as it flows through the oil passage 13, preventing the return spring 14 from quickly rebounding. This achieves the effect of reducing... The device's vibration damping function is designed to prevent damage to precision internal components. When adjusting the device's vibration damping capability, operators simply need to remove the limit pin 5 and slightly rotate the adjustment bracket 4. This causes the adjustment bracket 4 to rotate the lifting shaft 10 and the rotating adjustment plate 11, thereby adjusting the position of the rotating adjustment plate 11 relative to the external oil passage 13 of the extrusion plate 12, and thus adjusting the cross-sectional area of the oil passing through the oil passage 13. Finally, the operator inserts the limit pin 5 into the corresponding adjustment hole 9. The device is equipped with the rotating adjustment plate 11. The combination of the lifting shaft 10 and the rotating adjustment bracket 4 allows operators to easily adjust the position of the rotating adjustment plate 11 and the external oil passage 13 of the extrusion plate 12, thereby adjusting the cross-sectional area of the oil passing through the oil passage 13, and thus achieving the purpose of adjusting the shock absorption strength of the device. This makes the device more convenient to use, enhances its performance, reduces the difficulty of use, and allows operators to adjust the shock absorption strength of the device according to their needs, making the device more flexible. When the device vibrates during movement, the universal wheel 7 will push the extrusion plate 12 upward through the connecting rod 15, causing the connecting rod 15 to squeeze the hydraulic oil inside the hydraulic cylinder 18, thereby allowing the hydraulic oil to flow through the oil passage 13 inside the fixed cylinder 3, enabling the device to absorb vibration and making the device move more smoothly, preventing damage to the precision parts inside the device under vibration. The installation of the outer plate 8 and the limiting bracket 5 allows for the limiting of the rotating adjustment bracket 4, thereby limiting the position of the external oil passage 13 of the rotating adjustment plate 11 and the extrusion plate 12, ensuring the stability of the device's shock absorption strength.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
