With increase fire proof sealing strip 6 on end stone 5 respectively, 1 right side point of 1 left side of left layer door and right layer door during realizing that layer door 1 is closed
It does not seal.
As shown in attached drawing 5,6,7,8, upper sealing structure of the invention, the upper ejector pin handle 71 and upper ejector pin 72 of pushing structure
It is connected as one and is arranged on layer door 1, moved with the horizontal fortune work(of layer door 1.Upper pivoted arm 74, the upper pivoted arm 74 of sealing mechanism
On sealing strip 6, upper shaft 75, upper compressed spring 73 be arranged on head trim 2, wherein on upper pivoted arm 74 and upper pivoted arm 74
Sealing strip 6 can make the rotary motion of certain angle around upper shaft 75.In the state of the unlatching of layer door 1, upper ejector pin 72 is not at rear turn
The underface of arm 742, pushing mechanism do not have sealing mechanism any effect, and upper pivoted arm 74 is pushed up upper limit by upper compressed spring 73
The position of block 76, so that the sealing strip 6 on upper pivoted arm 74 is got along well, layer door 1 contacts, so as to not influence the normal fortune of layer door 1
It is dynamic；In the case where 1 shape of layer door closes state, pivoted arm 742 is to moving up after upper ejector pin 72 is located at the underface of rear pivoted arm 742 and can push
It is dynamic, that is, taper one end of ejector pin 72 is gone up as the movement of layer door 1 is gradually moved into the underface of rear pivoted arm 742, on overcoming
The active force of compressed spring 73 makes pivoted arm 74 do counter-clockwise rotary motion, so as to make the sealing strip 6 and layer door on preceding pivoted arm 741
1 contact, so as to fulfill the sealing between layer door 1 and head trim 2, so as to fulfill the fire-proof smoke-proof sealing above entire door system.
As shown in attached drawing 5,9,11,12,13,1 side door of layer door set 4 and lower ejector pin 84 link together, lower compressed spring peace
Seat 86, lower compressed spring 87, lower ejector pin block hitting 83, lower rotary shaft 81 and lower pivoted arm 82 are filled on layer door 1, and with the water of layer door 1
It puts down movement and moves.Ejector pin block hitting 83, lower pivoted arm 82 and sealing strip 6 thereon are wherein descended as an entirety, it can be around lower rotary shaft 81
Make the rotary motion of certain angle, the sealing strip 6 on 6 and second pivoted arm 822 of sealing strip on the first pivoted arm 821 is separately fixed at
On bottom surface before and after lower pivoted arm 82.Under 1 opening of layer door, lower pivoted arm 82 is pushed up lower limit by the effect of lower compressed spring 87
The position of block 85, lower ejector pin block hitting 83 is not in the surface of the second pivoted arm 822, so that the sealing strip 6 on the first pivoted arm 821
Discord landing sill 3 contacts, 1 interior side contacts of the discord layer of sealing strip 6 door on the second pivoted arm 822, so as to not influence layer door 1
Proper motion；Under 1 closed state of layer door, lower ejector pin block hitting 83 is located at the surface of lower ejector pin 84 and can push the second pivoted arm
822 move upwards, and the first pivoted arm 821 moves downward, and overcome the active force of lower compressed spring 87 so that lower pivoted arm 82 is made counterclockwise
Movement, so as to contact sealing strip 6 on the first pivoted arm 821 and landing sill 3, sealing strip 6 and layer door on the second pivoted arm 822
1 interior side contacts, so as to fulfill the fire-proof smoke-proof sealing below entire door system.
Embodiment 2
As shown in attached drawing 6,10, the present embodiment and embodiment 1 the difference lies in：Separation control in lower sealing structure
Device processed is different.
The separation control device includes lower stretching spring mounting seat 88 and lower extension spring 89；The lower extension spring peace
Dress seat 88 is fixed on the layer door 1 of 821 top of the first pivoted arm；Pacify with lower extension spring 89 upper end of the lower extension spring 89
It pretends to connect, lower end is connect with the upper surface of the front end of the first pivoted arm 821.
As shown in attached drawing 6,10,11, the lower sealing of door system can also be realized with the form of extension spring, be changed to down
Extension spring 89 and lower extension spring 89.Under door opening state, because lower pivoted arm 82 is moved down in the effect of lower compressed spring 87 to
The position of limited block 85, so that the sealing strip 6 on the first pivoted arm 821 is got along well, landing sill 3 contacts, on the second pivoted arm 822
Sealing strip 6 get along well 1 interior side contacts of layer door, so as to not influence the proper motion of layer door 1；Under 1 closed state of layer door, lower ejector pin
Block hitting 83 is beaten with the movement of layer door 1 on lower ejector pin 84, so as to which the active force for overcoming lower extension spring 89 causes lower pivoted arm 82
Make counterclockwise movement, so as to contact sealing strip 6 on the first pivoted arm 821 and landing sill 3, the sealing on the second pivoted arm 822
1 interior side contacts of item 6 and layer door, so as to fulfill the fire-proof smoke-proof sealing below entire door system.
