[0056] Compared with the prior art, the present application has significant advantages and beneficial effects, which are embodied in the following aspects:

[0057] 1、The pressure-increasing sleep cabin in the present application is composed of an assembled sleep cabin and a pressure-increasing integrated control cabinet, wherein the sleep cabin is composed of an outer frame structure, an inner frame structure, a door frame structure, a top plate, a bottom plate, a wall plate, a pressure-bearing air-tight door, a sealing strip and a sealing pressure plate, the outer frame structure is a cuboid structure, the inner frame structure is installed on the top surface, the bottom surface and each side surface of the outer frame structure, and the door frame structure is installed on one side surface of the outer frame structure, so that the outer frame structure, the inner frame structure and the door frame structure jointly form a dense-rib aluminum alloy structure and form a support bearing system; the installation edges of the outer frame structure, the inner frame structure, the door frame structure, the top plate, the bottom plate and the pressure-bearing air-tight door are sealed by the sealing strip, the sealing strip is pre-tightened and installed on the dense-rib frame structure through the sealing pressure plate, and when the pressure-bearing air-tight door is closed, the sleep cabin forms a closed space; the pressure-increasing integrated control cabinet is composed of a closed mobile cabinet body, control equipment, air supply and exhaust equipment and air conditioning equipment, wherein the control equipment, the air supply and exhaust equipment and the air conditioning equipment are arranged in the mobile cabinet body, the inside of the mobile cabinet body is divided into three layers by partitions, each partition is uniformly provided with air permeable holes, the air conditioning equipment is placed on the lowermost layer, the control equipment is placed on the partition of the middle layer, and the air supply and exhaust equipment is placed on the partition of the uppermost layer, and the air supply and exhaust equipment is connected to the sleep cabin through an air path system. The outer frame and the inner frame formed by splicing aluminum alloy profiled steel bar members are bolted to form a dense-rib frame structure as the main bearing structure of the pressure-increasing sleep cabin, and this detachable scheme has the advantages of convenient transportation, high assembly efficiency, light weight, the ability to arrange a large-size pressure-increasing sleep cabin inside an existing building and suitability for ordinary residences. Meanwhile, the structure can be repeatedly disassembled and assembled to meet the needs of users who move to a new place.

[0058] 2、The pressure-increasing sleep cabin in the present application adopts modular design for the movable lightweight pressure-increasing oxygen supplement shelter, the outer frame structure, the inner frame structure, the door frame structure and the pressure-bearing air-tight door formed by splicing aluminum alloy profiled steel bar members are bolted to form a dense-rib frame structure, which can be transported to the site for debugging and use after assembly; or can be directly transported to the site, arranged and expanded in the plane as needed, and greatly improve the convenience of transportation and hoisting of the pressure-increasing oxygen supplement shelter.

[0059] 3、The component splicing nodes of the outer frame structure and the inner frame structure are installed by double-row bolts to avoid air-tightness defects caused by unilateral stress of the sealing rubber strip and deflection of the two side beams; meanwhile, the double-row bolts can ensure uniform compression of the sealing rubber strip, thereby increasing the service life of the sealing rubber strip.

[0060] 4、The pressure-tight door in the application adopts aluminum alloy structure with inner and outer double-skin structure, which is light in weight and strong in strength. At the same time, high air-tightness nodes are adopted, and the pressure difference between the inside and outside of the structure can be used to further enhance the air-tightness of the structure.

[0061] 5、The pressure-tight door in the embodiment integrates air-tightness, pressure resistance and fire resistance, which is composed of a door leaf, an upper sliding rail structure and a lower sliding rail structure, a door lock and an air-tight door vertical limiting structure, etc. The pressure-tight door forms a positive pressure in the sleep cabin body to ensure the sealing effect. The movable door leaf is automatically driven to translate into the door frame structure through the upper sliding rail structure and the lower sliding rail structure. When the door leaf is closed, the door leaf translates to the door frame structure and presses the sealing rubber strip arranged on the door frame structure, so as to tightly seal it. When the door leaf is opened, the door leaf moves to one side of the door frame structure, without occupying the internal space. In addition, the door leaf closes to the position to generate the same clamping pressure around the door frame structure, which can improve the stability of the pressure-tight door, and is suitable for the situation that the air pressure inside and outside the pressure-increasing building is different, so as to always maintain the stability and sealing property of the structure.

[0127] The existing pressure-boosting building or pressure-boosting cabin is mostly a flat door and an inward opening door, which is generally sealed through a sealing element arranged between a door plate and a door frame. When sealing, a certain initial pressure needs to be manually applied by a person to make the sealing element tightly fit the cabin door and the cabin door frame, and then the sealing is further performed through continuously increasing pressure.
