After inflation, the air inlet 101 and air outlet 102 are sealed, creating a sealed environment within the cavity. Experiments are performed inside the cavity using the glove 300, facilitating control of the internal temperature, humidity, and other environmental factors. Since the glove 300 is detachably connected to the chamber body 100, it is convenient to handle any damage to the glove 300. Replace gloves 300 promptly to avoid affecting the sealing effect inside the chamber 100. When not in use, open the vent 102 to release the internal gas, making the entire chamber 100 compact, easy to fold and store, and easy to carry for use in different environments. In addition, by setting straps 200 on the chamber 100, with at least one strap 200, the chamber can be secured to maintain its shape and stability when filled with gas due to its lightweight flexible material. When the chamber is deflated and not in use, the chamber 100 can be tied up for storage and easy carrying. Furthermore, the straps 200 can also be used to hang the chamber 100 on a wall or other support, reducing the space occupied on the ground.

[0048] In an embodiment of this utility model, an opening is provided on one side of the box body 100. The portable assembly experimental box also includes a sealing part 110 and a zipper 120.

The second fixing ring 500 includes an annular structure and a mounting ring disposed along the outer periphery of the annular structure and extending radially outward. The annular structure is sleeved on the outer periphery of the first end 410, and an outwardly folded glove 300 is also included between the annular structure and the first end 410. The mounting ring is attached to the outer wall of the housing 100 and passes through the mounting ring, the housing 100 and the second end 410 in sequence from the outside to the inside by rivets. 0, so that the second fixing ring 500 is fixed on the box body 100. Due to the setting of the second fixing ring 500, the end of the glove 300 that extends out of the box body 100 and is folded outward is also fixed between the second fixing ring 500 and the first end 410, thus achieving a seal between the glove 300 and the first end 410. In addition, the second end 420 is bonded to the inner wall of the box body 100, which also achieves a seal between the second fixing ring 500 and the box body 100 and between the first fixing ring 400 and the box body 100.

[0058] In another embodiment, please refer to Figure 4The second fixing ring 500 has an annular structure with an internal thread on the inner ring and an external thread on the part of the first end 410 that extends out of the first opening 103. When the glove 300 extends out of the first opening 103 and folds outward to cover the first end 410, the second fixing ring 500 engages with the first end 410 and is threadedly connected to it, thereby sealing the end of the glove 300 between the first fixing ring 400 and the second fixing ring 500. Regardless of whether the second fixing ring 500 is riveted to the box 100 or threaded to the first end 410, the glove 300 can be detached and replaced by opening the second fixing ring 500. This facilitates direct replacement of the glove 300 when it is worn, reducing costs. Furthermore, the second fixing ring 500 makes the connection between the glove box 300 and the first end 410 tighter, preventing the glove 300 from falling off when subjected to external impact, thus enhancing the stability of the connection.

[0059] In an embodiment of this utility model, the air inlet 101 is used to connect to an air source to inflate the inside of the housing 100, so that the gas inside the housing 100 flows out from the air outlet 102. One-way valves 700 are installed in the air inlet 101 and the air outlet 102 respectively. After inflation is completed, a cover is installed in the air inlet 101 and the air outlet 102 respectively to seal the air inlet 101 and the air outlet 102.

[0060] Please refer to Figure 1 and Figure 2 When using the experimental chamber, the interior of the chamber 100 needs to be inflated to maintain the internal air pressure and prevent external contaminants from entering. Additionally, for some experiments with environmental requirements, inert gases such as nitrogen or argon may be added. Specifically, the air inlet 101 is connected to a gas source to inflate the chamber 100, causing the gas inside the chamber 100 to escape through the air outlet 102, ensuring that the entire cavity contains the required gas. Both the air inlet 101 and the air outlet 102 are designed to protrude outwards to connect the inside and outside of the cavity. Furthermore, [the following is a list of components / installations] are installed inside the air inlet 101 and the air outlet 102 respectively. A one-way valve 700 and an air inlet 101 are connected to an air source via an air pipe. When the air source is opened, the gas pushes open the one-way valve 700 at the air inlet 101 and enters the accommodating cavity. The air pressure in the accommodating cavity gradually increases, causing the original gas in the accommodating cavity to be discharged at the air outlet 102 until the accommodating cavity is filled with inert gas or the required gas. The one-way valve 700 ensures that the gas can only flow in one direction, which can prevent external pollutants and air from entering the interior of the chamber 100 and also prevent the backflow of gas inside the chamber 100, ensuring the purity of the internal environment and making the interior of the chamber 100 an oxygen-free environment.

[0061] In one embodiment, after inflation is complete, the gas composition and density inside the chamber 100 reach the expected set value. A cover is installed at the vent 102 and connected to the vent 102 to disconnect the gas source. A cover is also installed at the inlet 101 and connected to the inlet 101, so that the accommodating cavity is in a closed state to prevent gas leakage and the entry of external pollutants. The chamber 100 maintains a certain positive pressure to keep the internal environment stable and ensure that the experimental process and experimental materials are not affected by the outside world. The chamber 100 is filled with inert gas, which can also prevent the corrosion of experimental materials and equipment. It is suitable for anaerobic operation. When storing some items that react with oxygen, it is necessary to maintain an anaerobic environment for a long time. For example, some metal powders such as magnesium and sodium, and some organic compounds such as aldehydes and ketones, are easy to react with moisture in the air and also need to be stored in an airtight environment. These are not listed here.

[0062] In another embodiment, the air inlet 101 is always connected to the air source through an air pipe, and the air enters the chamber 100, making the chamber 100 under positive pressure. Excess air is discharged at the air outlet 102, and the chamber 100 is in a state of gas circulation. Through gas circulation, the air in the chamber 100 can be continuously renewed, ensuring that the purity of the internal environment is always at the best. Even if there is a leak, the gas circulation can quickly replenish the air, preventing the accumulation of external pollutants. The pressure inside the chamber 100 is automatically regulated to ensure that the gas pressure is always within a stable range. This is suitable for operations that require oxygen-free conditions, such as the weighing of active metals, but is not limited to such situations.

[0063] In an embodiment of this utility model, the cover is inserted into the air inlet 101, that is, the cover is inserted into the end of the air inlet 101 that extends out of the box 100 to block the air inlet 101, or the cover has an internal thread that mates with the external thread on the air inlet 101 to form a threaded connection.

[0064] Similarly, the cover and the vent 102 are connected by either the cover being inserted into the vent 102 at one end extending out of the box 100 to block the vent 102, or the internal thread on the cover engaging with the external thread on the vent 102 for a threaded connection.

[0065] The one-way valve 700 is made of flexible material. Flexible one-way valve 700 has good elasticity and will deform to a certain extent when subjected to pressure impact. It can maintain good sealing performance after multiple uses. The material of one-way valve 700 can be silicone, nitrile rubber, neoprene rubber and fluororubber, etc., which have good elasticity and chemical stability. There is no specific limitation on the material of one-way valve 700.

[0066] In an embodiment of this utility model, the portable assembly experimental box further includes a sliding component 600, which is used to connect the strap 200 and the box body 100 to adjust the relative position of the strap 200 and the box body 100.

[0067] Please refer to the figure. The position of the strap 200 can be adjusted by the sliding component 600, making the experimental box easier to carry and secure. Whether in the laboratory or other environments, the position of the strap 200 can be adjusted according to the actual situation, improving the applicability of the experimental box. The flexible adjustment of the strap 200 can reduce the shaking of the experimental box during movement, ensuring the safety of the internal equipment. The strap 200 can also be used to fix the experimental box and prevent it from moving during the experiment. In addition, by setting the sliding component 600, the wear of the strap 200 in direct contact with the box body 100 is reduced, protecting the surface of the box body 100 and extending the service life of the box body 100.

[0068] In an embodiment of this utility model, the sliding component 600 includes:

[0069] Mounting part 610 is installed on the outside of housing 100;

[0070] The guide section 620 is provided on the mounting section 610 and extends in a straight direction;

It should also be noted that at least one strap 200 is provided, and at least one sliding assembly 600 is provided, with each sliding assembly 600 corresponding to one strap 200. In this embodiment, the sliding assembly 600 and Four straps 200 are provided, corresponding to the cubic box 100. The sliding components 600 are provided on the four edges of the upper part of the box 100. The sliding sleeves 630 move along the edges so that the position of the straps 200 can be adjusted to better accommodate the box 100. In addition, rubber is provided between the sliding sleeves 630 and the guide part 620 to provide appropriate resistance and prevent the sliding sleeves 630 from moving on their own. Furthermore, the flexibility of the components can be improved by adding or reducing the number of combinations of sliding sleeves 630 and straps 200 on the sliding components 600, that is, one or more sliding sleeves 630 are provided on one guide part 620, and each sliding sleeve 630 is connected to one strap 200.

[0073] In embodiments of this utility model, the box body 100 and the sealing part 110 are made of polypropylene. Polypropylene is lightweight, which can reduce the overall weight of the experimental box and make it easy to carry. Polypropylene also has good chemical corrosion resistance. Nylon can also be used.
