Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
The application principle of the present invention is explained in detail below in conjunction with the accompanying drawings.
A kind of gas-tight door of the invention as Figure 1-3, is included in door body 1 and the He of the door handle set in door body 12
Mechanical driving, described mechanical driving include driving wheel 3, driven pulley 4 and rack 6, and described driven pulley 4 is placed in machine
The centre position of tool transmission component, the frame side that described driving wheel 3 is disposed in proximity to open the door are in contact with driven pulley 4, main
On same horizontal linear, described rack 6 connects the central rotating shaft of driving wheel 3 and driven pulley 4 with the opposite side of driven pulley 4
Touch.The rotating shaft of door handle 2 and the central rotating shaft of driving wheel 3 are coaxially fixed, and door handle 2 can drive connected master during rotating
The synchronous axial system of driving wheel 3.Because described rack 6 is arranged on the upper end of slide bar 5, the bottom of the described lower end of slide bar 5 and pressing plate 7 are solid
Fixed connection, the lower section of pressing plate 7 are provided with seal 8, and therefore, described door handle 2 passes through mutual between mechanical driving gear
Coordinate can moving up and down with moving slide-bar 5, so as to drive moving up and down for the seal 8 of bottom.
When gas-tight door is closed, door handle 2 is located at horizontal direction, and pressing plate 7 now extends downwardly from, installed in the lower section of pressing plate 7
Seal 8 receive the common squeezing action on pressing plate 7 and ground, plastic deformation occurs, is filled between door and ground
Gap, form the environment of sealing.Described seal 8 is EPDM material, and this high polymer material not only has excellent
Elastic performance, can ensure the sealing of closed environment, but also with excellent decay resistance, ageing-resistant performance, resistance to
Vapor performance and heat resistance, suitable for the installation of the gas-tight door under a variety of environment.
In the present invention, rail slider 9 and reinforcement 10 are also provided with door body 1, it is ensured that slide bar 5 and bottom plate 7 are maintained at
Both vertically and horizontally, dimensional discrepancy is not produced.In the door body 1 several are sequentially fixed along its short transverse
Rail slider 9, in vertical direction, described rail slider 9 is set on the same line, and described slide bar 5 runs through all rails
Road sliding block 9, it can ensure that slide bar can smoothly move and not shift and wave.Reinforcement is there is also mounted on gas-tight door
10, described reinforcement 10 is connected with described slide bar 5 in certain angle, and angle between the two is arranged on 30~45 degree,
One end of reinforcement 10 is fixed with slide bar 5, and the other end is fixed on pressing plate 7, shape between such slide bar 5, reinforcement 10 and pressing plate 7
The triangular structure stable into one, it can be ensured that pressing plate 7 can remain in the horizontal direction.
The distance that described slide bar 5, pressing plate 7 and 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, flexible connector 11 is additionally provided between described door body 1 and pressing plate 7, all the time
The gap of filling therebetween.Flexible connector 11 described in patent of the present invention is flexible connector, the upper of connector of stretching
Lower end respectively with along fixed and seal, flexible curtain contracts with moving up and down for pressing plate to be stretched, and ensures pressure in the lower edge of door body 1 and pressing plate 7
Its airtight performance is not changed with moving up and down for pressing plate 1 along with the space between the lower edge of door body 1 on plate 7.
The mechanical driving of the gas-tight door of the present invention is arranged on the side opened the door, and described driving wheel 3 is disposed in proximity to
The frame side of enabling is in contact with driven pulley 4, and described rack 6 is in contact with the opposite side of driven pulley 4.So it is able to ensure that
During door handle 2 presses down on during enabling, rack 6 drives connected slide bar 5 to move up；When closing gas-tight door, door knob
During hand 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 pulley 4 is driven to rotate counterclockwise, driven pulley 4 moves upwards in opposite directions relative to the rack 6 on right side, so as to 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 pulley 4 is driven to move in the direction of the clock, driven pulley 4 is relative to the opposite motion upwards of rack 6 in left side, slide bar 5, bottom plate 7
Moved up with seal 8.
For gas-tight door in opening or movement, door handle 2 remains the state pushed, 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 that pushes 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 pulley 4 is and then according to rotationally clockwise, the right side of driven pulley 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, ensure the air-tightness in space in door.
