In the optional embodiment of this embodiment, the last spout both ends that lie in of sliding structure all are provided with limit stop.
In an optional embodiment of this embodiment, a stiffening rib is disposed between the connecting member and the sealing platen.
In the optional implementation of this embodiment, door frame top and bottom all are provided with sealed baffle towards airtight door body one side, and the sealed baffle of both sides respectively with the sealing strip butt of airtight door body top and bottom.
In an optional implementation manner of this embodiment, an observation window is disposed on the hermetic door body.
In an alternative embodiment of this embodiment, a door handle is provided on the containment door body.
In the use, the user is when closing the airtight door, the sealing strip mutual contact of the airtight door body relative of both sides is sealed, and the sealing strip of airtight door body top and bottom and the sealing baffle contact of door frame top and bottom are sealed, then remove the slider to suitable position, then rotatory adjusting bolt for adjusting bolt drives the connecting piece and moves towards the airtight door body, and then makes sealing plate support the seam crossing at airtight door body and door frame, seals the seam of articulated department.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the use of the double-open type protective airtight door by a user becomes more convenient and efficient, and the airtight door has good airtightness when being closed; the utility model has the advantages of simple structure, convenient maintenance, low processing cost, good use effect and the like.
