The sealing structure of asymmetry improves air-tightness, meets the air-tightness index of passive type aluminium alloy door.
What the technical solution of the utility model was realized in：
A kind of passive type with internal seal structure asymmetry aluminium alloy door for building, including：Threshold and door leaf, institute
Door leaf is stated to be located at the top of the threshold；It is step type at the top of the threshold, the door leaf bottom is inverted ladder-shaped, the step type
It is close that first of sealing, second sealing and third road are disposed between threshold and the inverted ladder-shaped door leaf from outside to inside
Envelope.
Further, it is disposed with the first ladder, the second-order gradually increased from outside to inside at the top of the stepped threshold
Ladder and third ladder；The inverted ladder-shaped door leaf bottom is disposed with the first inverted steps and second gradually increased from outside to inside
Inverted steps；It is provided with the first extension sealing frame on the outside of first inverted steps, described first is sealingly fastened in and prolongs for described first
On long sealing frame；The second sealing frame is provided on the outside of the third ladder, the second is sealingly fastened in second sealing
On frame；It is provided with third on the inside of the third ladder and extends sealing frame, it is close that the third road is sealingly fastened in the third extension
It seals on frame.
Further, it is contacted on the outside of first of sealing and second ladder, the second sealing and described first
The interior side contacts of inverted steps, second inverted steps bottom are provided with sealing plate, and the sealing plate connects with the three seals
It touches.
Further, first of sealing, second sealing and three seals are sealing joint strip.
The utility model improves air-tightness using the sealing structure of asymmetry, meets the airtight of passive type aluminium alloy door
Property index.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is a kind of passive type with internal seal structure asymmetry for building in the utility model specific embodiment
The structural schematic diagram of aluminium alloy door；
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
In specific embodiment of the utility model, see that Fig. 1, a kind of passive type with internal seal structure are for building non-
Symmetry aluminium alloy door, including：Threshold 2 and door leaf 1, door leaf 1 are located at the top of threshold 2；2 top of threshold is step type, door leaf 1
Bottom be it is inverted ladder-shaped, between stepped threshold 2 and inverted ladder-shaped door leaf 1 from outside to inside successively have setting first sealing 3,
Second sealing 4 and three seals 5.
In specific embodiment of the utility model, see that Fig. 1, the top of stepped threshold 2 are disposed with from outside to inside
The first ladder 21, the second ladder 22 and the third ladder 23 gradually increased；1 bottom of inverted ladder-shaped door leaf is set successively from outside to inside
It is equipped with the first inverted steps 11 and the second inverted steps 12 gradually increased；First inverted steps, 11 outside is provided with the first extension sealing frame
111, first of sealing 3 is fixed on the first extension sealing frame 111；23 outside of third ladder is provided with the second sealing frame 231,
Second sealing 4 is fixed on the second sealing frame 231；23 inside of third ladder is provided with third and extends sealing frame 232, third
Road sealing 5 is fixed on third and is extended on sealing frame 232.
In specific embodiment of the utility model, Fig. 1 is seen, first of sealing 3 and 22 outer side contacts of the second ladder, second
The interior side contacts of road sealing 4 and the first inverted steps 11,12 bottom of the second inverted steps are provided with sealing plate 121, sealing plate 121 and the
Three seals 5 contact.
In specific embodiment of the utility model, Fig. 1, first of sealing 3, second sealing 4 and three seals 5 are seen
It is sealing joint strip.
In specific embodiment of the utility model, Fig. 1 is seen, under the threshold 2 in the utility model and 1 closed state of door leaf
Stair-stepping first sealing 3, second are passed through for the barrier not instead of symmetry of air pressure for asymmetry relationship
4 grades of three seals 5 of sealing are gradually obstructed, and to reduce passing through for wind pressure, meet the air-tightness of passive type aluminium alloy door
It is required that.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
