Vapor performance and heat resistance, suitable for the installation of the gas-tight door under a variety of environment.
In the utility model, rail slider 9 and reinforcing rib 10 are also provided with door body 1, it is ensured that slide bar 5 and bottom plate 7 are protected
Hold both vertically and horizontally, do not produce dimensional discrepancy.It is if sequentially fixed along its short transverse is played in the door body 1
A dry rail slider 9, in vertical direction, the rail slider 9 is set on the same line, and the slide bar 5 is through all
Rail slider 9, can ensure that slide bar can smoothly move and not shift and wave.It there is also mounted reinforcement on gas-tight door
Muscle 10, the reinforcing rib 10 is a certain included angle with the slide bar 5 to be connected, and angle between the two is arranged on 30~45
Degree, one end and the slide bar 5 of reinforcing rib 10 fix, and the other end is fixed on pressing plate 7, such slide bar 5, reinforcing rib 10 and pressing plate 7 it
Between form a stable triangular structure, it can be ensured that pressing plate 7 can remain in the horizontal direction.
The distance that slide bar 5, pressing plate 7 and the seal 8 is moved up and down by door handle 2 and mechanical driving is 10
~20mm, its shift motion are more than the gap between door and ground.When so door is closed, seal 8 can closely connect with ground
Touch.
In order to form good airtight environment, it is additionally provided between the door body 1 and pressing plate 7 and is telescopically connected part 11, all the time
The gap of filling therebetween.Part 11 is telescopically connected to be telescopically connected part described in the utility model patent, is telescopically connected part
Upper and lower side respectively with along fixed and seal, flexible curtain contracts with moving up and down for pressing plate to be stretched, and is protected on 1 lower edge of door body and pressing plate 7
Its airtight performance is not changed with moving up and down for pressing plate 1 along with the space between 1 lower edge of door body on card pressing plate 7.
The mechanical driving of the gas-tight door of the utility model is installed on the side opened the door, and the driving wheel 3 is arranged at
It is in contact close to the frame side opened the door with driven wheel 4, the rack 6 is in contact with the opposite side of driven wheel 4.So can
During door handle 2 presses down on when ensuring to open the door, rack 6 drives connected slide bar 5 to move up；When closing gas-tight door,
During door handle 2 is returned to horizontal level, rack 6 drives connected slide bar 5 to move down.
The embodiment of L.H.flapped door as shown in Figure 1, the driving wheel 3 in mechanical driving are located at Far Left, rack 6 with from
The right side of driving wheel 4 is in contact, and door handle 2 presses down on, and drives driving wheel 3 to move in the direction of the clock, so that driving wheel 3
Driven wheel 4 is driven to rotate counterclockwise, driven wheel 4 moves upwards in opposite directions relative to the rack 6 on right side, so that with moving slide-bar
5 and the bottom plate 7 and seal 8 that are connected with slide bar 5 move up, it is contactless with ground when seal 8 moves up.
The embodiment of R.H.flapped door as shown in Figure 2, the driving wheel 3 in mechanical driving are located at rightmost, rack 6 with from
The left side of driving wheel 4 is in contact, and door handle 2 presses down on, and drives driving wheel 3 to rotate counterclockwise, so that driving wheel 3
Driven wheel 4 is driven to move in the direction of the clock, driven wheel 4 is relative to the opposite movement upwards of rack 6 in left side, slide bar 5, bottom plate 7
Moved up with seal 8.
Gas-tight door in opening or movement, door handle 2 remain push state, seal 8 all the time not with ground
Face contacts, so as to ensure that door can be opened smoothly.
When gas-tight door is closed, by taking L.H.flapped door as an example, during the door handle 2 of pushing is returned to horizontality, such as Fig. 3 institutes
Show.Door handle 2 drives driving wheel 3 to rotate in an anti-clockwise direction, and driven wheel 4 is and then according to rotationally clockwise, the right side of driven wheel 4
Moved downward relative to rack 6, band moving slide-bar 5, pressing plate 7 and seal 8 move down, so as to block between door and ground
Gap, ensures the air-tightness in space in door.
