Abstract: The door in the mine the importance of life -saving tank design was analysed. And using
gears meshing with the rack design of the door locking mechanism theory. Around the door latch plate
end of the corresponding part of the fabric has four bolt holes. As the latch plate out side was wedge
shape. By gear and rack gear drive latch plate into the corresponding bolt hole. Under the action of the
pressing force press the seal around the door in the state. Ensure that the door under the pressing
force on closely at the hull. Thereby ensuring the cabin temperature and air are smaller outside
influences. Rotation through the handle locking deter
