Description

Technical Field

[0001] The utility model relates to the technical field of square cabins, in particular to a test cabin. Background Art

[0002] Traditional shelters are mostly constructed from assembled panels, with sealants typically used to seal the joints. However, because sealants are significantly affected by environmental factors and can age or crack over time, they often struggle to maintain a reliable seal over time. While these shelters provide basic working environment safeguards, such as air conditioning systems to regulate temperature and humidity, and maintain a natural air pressure for normal breathing, they offer limited protection against outside air contaminants such as bacteria and viruses. Once these contaminants penetrate the cabin through leaky gaps, they pose a health threat to personnel inside, increasing the risk of infection. Therefore, for shelters that require specialized environments, improving their sealing and biosafety measures is crucial.

[0003] A Chinese patent (publication number: CN110005242A) discloses an accident-resistant shelter with fire, impact, and gunfire protection capabilities. The patent's overall skeleton uses a main frame, an inner frame, and an outer frame to form a high-strength overall frame. This not only ensures the high strength and high rigidity of the overall skeleton under impact conditions, but also reduces the metal area directly connecting the inside and outside of the shelter, which is beneficial for reducing heat transfer between the inside and outside of the cabin. However, during construction, it was found that the sealing performance of the cabin could not be effectively guaranteed, and it could not be used in an air environment contaminated by bacteria and viruses.
