Description

Technical Field

[0001] This application relates to the field of VOC environmental chamber sealing, and more specifically, to a VOC environmental chamber compartment sealing device for detecting hazardous substances in furniture. Background Technology

[0002] VOC is an abbreviation for volatile organic compounds, sometimes also represented by TVOC (total volatile organic compounds). In a general sense, VOC refers to volatile organic compounds; however, in an environmental context, it refers to a more reactive type of volatile organic compound—the kind that can cause harm. Although VOCs play an important role in certain products and processes, their volatile nature also brings potential environmental and health problems. VOC emissions lead to air pollution, participate in the formation of ozone and fine particulate matter, and may have adverse effects on human health, such as respiratory problems and exposure to harmful substances. Interior decoration materials such as engineered wood, wooden furniture, wooden flooring, carpets, carpet backings, and carpet adhesives, building decoration materials such as construction adhesives, and automotive interior materials and products all emit formaldehyde and VOCs. When the release is excessive and the concentration is too high, it may harm human health. A VOC environmental chamber is a testing device that reasonably simulates indoor environmental conditions and is commonly used to test for harmful volatile substances such as VOCs and formaldehyde.

[0003] The current VOC environmental chambers do not have good sealing between the doors and the chamber body, which affects the temperature and air pressure in the environmental simulation, resulting in distorted test data and reducing the practicality of the device. Utility Model Content

[0004] To address the above shortcomings, this application provides a compartmentalized sealing device for VOC environmental chambers used for testing hazardous substances in furniture. This device aims to improve the current VOC environmental chambers, where the sealing between the chamber door and the chamber body is not good enough, which affects the temperature and air pressure in the environmental simulation, leading to distorted test data and reducing the practicality of the device.

[0005] This application provides a VOC environmental chamber compartment sealing device for detecting hazardous substances in furniture, including an environmental chamber body and a sealing structure. The environmental chamber body includes an environmental chamber main body and self-locking universal wheels. The self-locking universal wheels are installed at the four corners of the bottom of the environmental chamber main body.

[0007] In the above implementation process, there are four sets of sliding plates and springs, which facilitate the limiting of the four sides of the sealing gasket. The sliding plates and springs make it easy to install and remove the sealing gasket, improving work efficiency and saving time and effort.

[0008] In one specific implementation, each of the four sides of the two sealing gaskets has a through-hole groove, and the sliding plate engages with the groove.

[0009] In the above implementation process, the sealing gasket has slots through all four sides, and the sliding plate engages with the slots, which can easily improve the limiting effect and make the installation of the sealing gasket more stable.

[0010] In one specific implementation, both the mounting plate and the door panel are provided with sliding grooves, and the sliding plate is slidably connected to the sliding grooves.

[0011] In the above implementation process, the sliding connection between the skateboard and the track makes it easy to limit the movement of the skateboard, making the movement of the skateboard more stable.

[0012] In one specific implementation, a pull block is provided on one side of the skateboard.

[0013] In the above implementation process, by setting a pull block on one side of the skateboard, the user can easily drive the skateboard to move, so that the skateboard can be released from the sealing pad, saving time and effort.

[0014] In one specific implementation, a handle is provided on one side of the door panel.

[0015] In the above implementation process, by setting a handle on one side of the door panel, users can easily open the door panel, which is convenient and quick.

[0016] In one specific implementation, the mounting plate has a through hole.

[0017] In the above implementation process, by creating a through hole through the mounting plate, the product can be easily inserted into the main body of the environmental chamber for testing.

[0018] In one specific implementation, both the mounting plate and the door panel have placement grooves on one side, and the sealing gasket is placed in the placement groove.

[0019] In the above implementation process, by setting the sealing gasket in the placement groove, the sealing gasket can be installed quickly and easily, and the positioning is convenient, thus improving the installation efficiency.

[0020] Compared with the prior art, the beneficial effects of this application are as follows: by pushing the door panel, the sealing gasket is brought into contact with the sealing gasket set on one side of the mounting plate, which facilitates quick compression and effective sealing, thus improving the sealing effect. The setting of the snap-fit ​​component facilitates quick disassembly and assembly of the sealing gasket, making it easy to replace the sealing gasket, thereby improving work efficiency and the practicality of the device.

The mounting plate 210 is fixedly connected to the environmental chamber body 110, and the door panel 220 is hinged to the environmental chamber body 110. The two sealing gaskets 230 are respectively disposed in the mounting plate 210 and the door panel 220. The snap-fit ​​assembly 240 is disposed in both the mounting plate 210 and the door panel 220. The snap-fit ​​assembly 240 snaps into the sealing gasket 230, and the two sealing gaskets 230 are in close contact with each other.

[0032] In a specific configuration, the snap-fit ​​assembly 240 includes a slide plate 241 and a spring 242. The slide plate 241 is slidably connected to the mounting plate 210 and snap-fitted to the sealing gasket 230. The two ends of the spring 242 are connected to the slide plate 241 and the mounting plate 210 respectively. There are four sets of slide plates 241 and springs 242, which facilitates limiting the four sides of the sealing gasket 230 respectively. The arrangement of slide plates 241 and springs 242 facilitates the installation and removal of the sealing gasket 230, improves work efficiency, and saves time and effort.

[0033] In the specific setup, slots are provided through all four sides of the two sealing gaskets 230, and the sliding plate 241 engages with the slots. The presence of slots through all four sides of the sealing gaskets 230 and the engagement of the sliding plate 241 with the slots can improve the limiting effect and make the installation of the sealing gaskets 230 more stable.

[0034] In the specific setup, both the mounting plate 210 and the door panel 220 are provided with sliding grooves, and the sliding plate 241 is slidably connected to the sliding grooves.
