Embodiment Construction

[0041] Such as Figure 1-3 As shown, a double-leaf non-threshold moisture-proof airtight door with high sealing reliability is used in warehouses with moisture-proof requirements, including a door frame 1 with a sealing strip, a threshold 2, and two seals pressed against the door frame 1 by a lock 41 On the bar and the door leaf that is rotatably connected with the door frame 1, the door leaf includes an earlier closing door leaf 31 and a rear closing door leaf 32 whose edge is pressed on the first closing door leaf 31 edge.

[0042]Note that no threshold in the present invention does not actually mean that there is no threshold, but that the threshold will not hinder the passage of vehicles. In the industry practice of the technical field involved in the present invention, such a threshold that does not hinder the passage of vehicles is generally not regarded as a threshold , "no threshold" is a term in the industry, which refers to the threshold that does not hinder the pass...

Abstract

The invention relates to a door for special purposes, and discloses a double-leaf doorsill-free damp-proof airtight door with high sealing reliability and a door opening method thereof. The double-leaf doorsill-free damp-proof airtight door is used for a storehouse with the damp-proof requirement and comprises a door frame with a sealing strip, a doorsill and two door leaves which are pressed on the sealing strip of the door frame through a lock and rotationally connected with the door frame; the door leaves comprise the first closed door leaf and the second closed door leaf; the first closed door leaf and the second closed door leaf are engaged at the overlapped position, and the engaged position is filled with a center joint sealing strip; the doorsill is sloped towards the two sides to form slope faces so that vehicles can conveniently pass through the doorsill; and bottom sealing strips are inlaid in the lower surfaces of the door leaves and tightly attached to one slope face of the doorsill. According to the double-leaf doorsill-free damp-proof airtight door, the problem that the sealing effect of the center joint position of the door is poor is solved, the problem that water vapor invades from the bottoms of the door leaves is solved, and the problem that the local sealing effect becomes poor due to uneven stress is solved; and therefore the double-leaf doorsill-free damp-proof airtight door has very high sealing reliability.

Description

technical field [0001] The invention relates to a special-purpose door, in particular to a double-leaf non-threshold moisture-proof airtight door with high sealing reliability and a method for opening the door. Background technique [0002] Civil air defense door is a kind of door with special purpose. It not only prevents the entry and exit of irrelevant personnel like conventional doors, but also prevents the shock wave of explosion and the entry of poisonous gas. There are sealing strips on the door frame and sill of the civil air defense door, and the door leaf is pressed against the sealing strip through locking to achieve sealing. A latch is a column that is pushed forward after the shaft rotates, usually using a bolt or cam compression mechanism. [0003] Among them, the single-leaf civil air defense door is narrow and is usually used in various civil air defense projects, and the double-leaf civil air defense door is wide and is usually used in various warehouses to...
