Description

Technical Field

[0001] The utility model belongs to the field of civil air defense door equipment, in particular to a civil air defense closed door capable of preventing gears from rusting. Background Art

[0002] Air-defense closed doors are a type of door used for protection in civil air defense projects. If an air-defense closed door is idle for a long time, the protective layer on the surface of its gear may fail, which is prone to rust. At the same time, the lack of sufficient lubrication of the gear will increase friction and accelerate the process of wear and corrosion. Therefore, there is a problem that there is no special anti-gear rust structure in the actual use of the air-defense closed door. The lack of anti-gear rust structure means that the gear is easily affected by factors such as humid environment and corrosive substances during long-term use, thus causing rust. Once the gear is corroded, its performance will be greatly reduced, which may cause the opening and closing of the air-defense closed door to be unsmooth, affecting the normal performance of its protective function. This is because there is a lack of parts with an anti-gear rust structure. The lack of parts with an anti-gear rust structure will not only cause the above problems, but also may cause rust and accelerate the wear of the gear, shorten its service life, and increase the cost and difficulty of maintenance. Moreover, if in an emergency, the air-defense closed door cannot work normally due to gear rust, it will pose a serious threat to the safety of people's lives and property, so it is necessary to propose a new structure to solve the above technical problems.
