The rescue capsule partition sealing door is mainly used for partitions of rescue capsules.

Description

technical field [0001] The rescue cabin partition sealing door of the invention belongs to the technical field of mining rescue cabin sealing doors. Background technique [0002] The design of the rescue cabin generally focuses on the design of the cabin section and the performance of the front hatch, while ignoring the design of the partition airtight door. First of all, the existing partition airtight door and the door frame adopt a single hinge connection method, and only one or two points are locked, and the locking is unreliable; at the same time, when the partition airtight door is closed, the door frame and the door are squeezed on one side , resulting in uneven stress on the sealing strip between the door frame and the corresponding position of the door, which is prone to gaps and lacks good sealing. Secondly, the existing partition hermetic door ignores the sealing of the rotating shaft at the inside and outside opening handles. [0003] When a mining accident occ...
