To this end, this utility model embodiment provides a kind of fire-proof seal door, to improve above-mentioned asking
Topic.
Embodiment 1:
With reference to Fig. 1, fire-proof seal door 100, including doorframe 110, door-plate 120, fixed body 130,
The connector 140 of arc, fire prevention air bag 150 and air pump 160.
Doorframe 110 is arranged on the opening part of building masonry wall 200, and fixed body 130 is fixed on
On building masonry wall 200.
Fixed body 130 includes vertical fixing plate 131, upper mounted plate 132, bottom plate 133
With pivot 134.Upper mounted plate 132 and bottom plate 133 are horizontally disposed with, and respectively with vertical
The top and bottom of straight fixed plate 131 connect, the two ends of pivot 134 respectively with upper mounted plate
132 and bottom plate 133 connect.Vertical fixing plate 131 is fixed on building cavity 200
On.One end of connector 140 is connected with pivot 134.
The other end of connector 140 is connected with door-plate 120.With reference to Fig. 2 by being rotationally connected
Body 140, makes door-plate 120 enter doorframe 110 to close fire-proof seal door 100, or with reference to figure
3, make door-plate 120 depart from doorframe 110 to open fire-proof seal door 100.
With reference to Fig. 1, fire prevention air bag 150 is arranged on the inner peripheral surface of doorframe 110, anti-fire of moxibustion
Capsule 150 is connected with outside air pump 160.Air pump 160 is inflated to fire prevention air bag 150, with
Fire prevention air bag 150 is made to expand.When door-plate 120 is positioned at doorframe 110, door-plate 120
There is gap between the inner peripheral surface of side face and doorframe 110, this gap is for for fire prevention air bag 150
Expand after inflation.After fire prevention air bag 150 inflation, fire prevention air bag 150 and door-plate 120
Side face seals laminating, thus realizes the purpose sealed.
Owing to door-plate 120 is connected with fixed body 130 by the connector 140 of arc, thus
Avoid the pivot points between door-plate 120 and doorframe 110.Air pump 160 is by doorframe 110
After fire prevention air bag 150 on inner peripheral surface is full of gas, fire prevention air bag 150 can be with door-plate 120
Side face seal laminating, thus realize the complete seal of end of door plate 120 side face, stopped existing
With the presence of fire-proof seal door pivot points at be susceptible to gas leakage, cause flameproof effect not
Good.
Fire prevention air bag 150 is fabricated by by flame-retarded plastic, such as, add glass fibre or carbonic acid
The modified resin of calcium.
With reference to Fig. 4, in order to improve sealing property, it is also possible to fire prevention air bag 150 is carried out as
Lower configuration.
Fire prevention air bag 150 includes the first fire prevention air bag 151 and the second fire prevention air bag 152.The
One fire prevention air bag 151 constitutes ring-type along the inner peripheral surface extension of doorframe 110.Second fire prevention air bag
152 is ring-type along the inner peripheral surface extension composition of doorframe 110.First fire prevention air bag 151 and second
Gap is there is between fire prevention air bag 152.
First fire prevention air bag 151 and the second fire prevention air bag 152 can be at the side faces of door-plate 120
Two sealing surfaces of upper formation, thus improve sealing property.
With reference to Fig. 5, it is also possible to arrange the side face along door-plate 120 on the side face of door-plate 120
Extend and formed ring-type projection 121.The cross section of protruding 121 is rectangle.At door-plate 120
It is positioned at doorframe 110 and the first fire prevention air bag 151 and time the second fire prevention air bag 152 is full of gas,
Protruding 121 between the first fire prevention air bag 151 and the second fire prevention air bag 152, and is close to
First fire prevention air bag 151 and the second fire prevention air bag 152.So add the first fire prevention air bag
151, the second fire prevention air bag 152 and the contact area of doorframe 110 side face, further increase
Sealing property.
With reference to Fig. 6, it is also possible to it is semicircular form that projection 121 is arranged to cross section.
The cross section of protruding 121 is semicircle, there is not wedge angle, it is to avoid the first fire prevention air bag 151,
When second fire prevention air bag 152 is close to protruding 121, the wedge angle on protruding 121 is prevented fires first
Air bag 151 and the second fire prevention air bag 152 wear and tear.It addition, the first fire prevention air bag 151, the
Two fire prevention air bags 152 can form the sealing surface of arc when being close to protruding 121, arc close
Front cover can provide more excellent sealing property.
With reference to Fig. 7, it is also possible to arrange the first groove 122 and the on the side face of door-plate 120
Two grooves 123.First groove 122 extends and is formed ring-type along the side face of door-plate 120.The
Two grooves 123 extend and are formed ring-type along the side face of door-plate 120.First groove 122 and
The cross section of two grooves 123 is rectangle.It is positioned at doorframe 110 and first at door-plate 120 to prevent
When fire of moxibustion capsule 151 and the second fire prevention air bag 152 are full of gas, the first fire prevention air bag 151 embeds
In first groove 122, the second fire prevention air bag 152 embeds in the second groove 123.So increase
Add contacting of the first fire prevention air bag 151 and the second fire prevention air bag 152 and door-plate 120 side face
Area, further increases sealing property.
With reference to Fig. 8, it is also possible to first groove the 122, second groove 123 is arranged to cross section
For semicircular form.First fire prevention air bag the 151, second fire prevention air bag 152 embeds first
After groove the 122, second groove 123, it is possible to form the sealing surface of arc.The sealing of arc
Face can provide more excellent sealing property.
With reference to Fig. 9, it is also possible to offer air vent 153 on the first fire prevention air bag 151,
When first fire prevention air bag 151 and the second fire prevention air bag 152 are full of gas, air vent is just to second
Fire prevention air bag 152.
After the first fire prevention air bag 151 and the second fire prevention air bag 152 are full of gas, the first fire prevention
Partial air in air bag 151 enters the first fire prevention air bag 151 and the by air vent 153
Between two fire prevention air bags 152, the first fire prevention air bag 151 and the second fire prevention air bag 152 it
Between form malleation space 154, it is to avoid outside air passes through, thus improves sealing further
Performance.
Sealed groove 111, sealed groove 111 can also be set at the inner peripheral surface of doorframe 110
It is ring-type that inner peripheral surface along doorframe 110 extends composition, and sealed groove 111 is positioned at the first anti-fire of moxibustion
Between capsule 151 and the second fire prevention air bag 152.
Sealed groove 111 makes energy between the first fire prevention air bag 151 and the second fire prevention air bag 152
Enough storages are more from the air of the first fire prevention air bag 151, thus form bigger formation
Malleation space 154, improves sealing property further.
With reference to Figure 10, fire prevention air bag 150 also includes multiple being arranged on the first fire prevention air bag 151 He
Between second fire prevention air bag 152, and connect the first fire prevention air bag 151 and the second fire prevention air bag
The connection fire prevention air bag 155 of 152.
Connection fire prevention air bag 155 is set, increases fire prevention air bag 150 and door-plate 120 side face
Contact area, thus improve sealing property further.
The foregoing is only section Example of the present utility model, be not limited to this
Utility model, to those skilled in the art, this utility model can have various change
And change.All within spirit of the present utility model and principle, any amendment of being made, etc.
With replacement, improvement etc., within should be included in protection domain of the present utility model.
