[0002] A micro-hyperbaric oxygen chamber is a special enclosed device that provides users with a high-oxygen, comfortable environment by increasing the oxygen concentration and maintaining a certain micro-high pressure. This type of chamber is usually used in medical, health care, rehabilitation and other fields. It can effectively improve the user's blood oxygen saturation and has a significant effect on human health. However, since the pressure inside the cabin is higher than the external atmospheric pressure, the cabin needs to be highly airtight to prevent oxygen leakage or external gas from entering the cabin, ensuring the stability and safety of the internal environment.

[0003] In the prior art, the sealing of wire holes usually relies on filling and fixing with sealants. The specific steps of this method include: opening a wire hole on the bulkhead, passing the cable through the wire hole, and then filling a large amount of sealant around the wire hole to ensure airtightness (for example, the wire hole opened for connecting the air conditioner outdoor unit needs to be filled with sealant). Its disadvantages include that the application and filling of the sealant requires workers to repeatedly adjust and confirm the sealing effect, the curing of the sealant usually takes a long time, affecting the overall installation efficiency, a large amount of sealant filling will be wasted, and the adhesion performance and curing speed of the sealant are easily affected by environmental factors such as temperature and humidity, resulting in unstable sealing effect.

[0009] Preferably, the bulkhead sheet metal seat is provided with a strip-shaped inner groove in the middle, the length of the strip-shaped inner groove is greater than the diameter of the wire hole, and an anti-fool support strip is installed in the strip-shaped inner groove, and the end face of the anti-fool support strip is flush with the end face of the bulkhead sheet metal seat.

[0021] To achieve the above-mentioned purpose, the embodiment of the present invention provides a bulkhead wire sealing structure for a micro-hyperbaric oxygen chamber, referring to Figure 1 、 Figure 2 As shown, including:

[0022] A bulkhead sheet metal seat 1 for welding and fixing, wherein a wire hole 2 is provided in the middle of the bulkhead sheet metal seat 1;

[0023] A rubber disc 3 is provided on the bulkhead sheet metal seat 1, and a protruding support column 4 is integrally connected to one side of the rubber disc 3. The protruding support column 4 is provided with a threading hole that passes through the rubber disc 3;
