Description

Sealing structure, cabin door and manufacturing method Technical Field The invention belongs to the technical field of cabin door sealing, and particularly relates to a sealing structure, a cabin door and a manufacturing method. Background The shelter is used as a key module in special vehicles, field hospitals, radar communication equipment and emergency rescue systems, and the shelter body of the shelter is generally of an aluminum alloy or steel frame structure so as to realize rapid deployment, environment isolation and multifunctional integration. As a main opening part of the shelter structure, the sealing performance of the cabin door is directly related to the waterproof, dustproof, heat-insulating, airtight and radiation leakage-proof effects of the shelter, thereby affecting the reliability of internal equipment and the safety of personnel. The existing shelter cabin door generally adopts a structure that single-channel sealing rubber strips are circumferentially arranged on a door outer frame or a door page frame, and the sealing rubber strips are in linear contact with corresponding frame bodies after the cabin door is closed, so that the waterproof, dustproof and airtight performances of a foundation are realized. In order to ensure that the sealing rubber strip is closely attached to the surface of the frame body, a mechanical pressing point is arranged on the door outer frame or the door page frame, so that the cabin door applies a pressing force to the sealing rubber strip during locking, and the normal operation of the sealing structure is ensured. The width of the single pass bead is typically limited and the mechanical locking points can only be placed in a single location where the bead is covering, resulting in only one effective pinch point per segment of the seal. The single-channel adhesive tape structure is usually a plane or simple lip type contact, the sealing path is single, and a multi-stage foldback or labyrinth type blocking structure cannot be formed. When the pod door is in a high wind pressure, low pressure differential, rain or dust scouring environment, media may enter the pod along a shorter interface path, resulting in a limited overall seal rating. Disclosure of Invention The present invention is directed to a sealing structure, a door and a method of manufacturing the same, which solve the above-mentioned problems of the prior art. Provided are a sealing structure, a hatch door, and a manufacturing method, including: The door outer frame is provided with a first sealing rubber strip, and a first mechanical pressing point is arranged at the position where the door outer frame is adjacent to the first sealing rubber strip; The door frame is provided with a second sealing rubber strip, and a second mechanical pressing point is arranged at the position where the door frame is adjacent to the second sealing rubber strip; the first mechanical pressure point may be in contact with the second sealing strip and the second mechanical pressure point may be in contact with the first sealing strip. The door hinge is characterized by further comprising a B-shaped adhesive tape, wherein the B-shaped adhesive tape is arranged on one of the door outer frame and the door page frame, and a third mechanical pressing point which can be contacted with the B-shaped adhesive tape when the door hinge is arranged on the door outer frame or the door page frame. On the basis that the first sealing adhesive tape and the second sealing adhesive tape form double adhesive tapes, the additionally arranged B-shaped adhesive tape forms a third sealing line and is matched with a third mechanical pressing point to form an independent pressing pair. The first and second strips assume the primary seal, but when the first seal zone undergoes micro-deformation, the B strip assumes the secondary compensation seal, forming a pressure dispersion, rather than focusing on a single pass strip. The cabin door is closed at the first section, and the B-shaped adhesive tape can firstly contact a third mechanical pressing point due to the large section and large overhanging amount. The contact produces a directional primary compressive force that causes the door to be directed in a uniform, controllable closing direction, providing a stopping point guide for the door, such that the door is no longer positioned by means of hard-touch metal, but rather is directed to a correct position by the flexible strip, and when the first mechanical pressure point and the second mechanical pressure point compress against the respective sealing strips, the positions are more accurate and the compression force is more controllable. As a further embodiment of the invention, a first assembly groove for accommodating the B-shaped adhesive tape is formed on the door outer frame, a plurality of first rib plates are arranged on the first assembly groove along the length direction, and a first concave groove which is jointed with the first r
