The tooth of the first top surface rack gear 3-4 left end of engagement connection.
The fire-retardant door body 5-1 is made of steel plate.
The operation principle of the present invention is that:
A kind of fire resistant doorsets of the invention when in use can be pre- in wall by integral installation of the invention by installing frame 2
In the mounting groove stayed, control device 3 is then connected to power supply and is opened or closed by control switch, control device can be passed through
3 pairs of overhead doors 1 control, thus make its installing frame 2 inside carry out up and down direction elevating movement, when overhead door 1 from
When the inside of installing frame 2 slides down to bottom, the closure of fire resistant doorsets of the present invention is realized, when overhead door 1 is out of installing frame 2
When sliding into the top on lateral, the unlatching of fire resistant doorsets of the present invention is realized；The control device 3 is risen in control overhead door 1
When dropping work, electric pushrod 3-1 is connected to power supply and is opened by control switch, electric pushrod 3-1 passes through push-and-pull connecting rod 3-3 band
Dynamic first rack gear 3-4 is when the inside of runner frame 3-5 slides a distance to the right, the tooth of the first trailing flank rack gear 3-4 right end
Engagement can drive linkage gear 3-6 to be rotated clockwise, and the first wheel shaft can be driven when linkage gear 3-6 is rotated clockwise
3-7 and the drive sprocket 3-8 being fixedly connected on the first wheel shaft 3-7 are rotated clockwise, and drive sprocket 3-8 can when rotating
To be rotated clockwise by chain-driving by movable sprocket 1-4, external screw thread can be driven when being rotated clockwise by movable sprocket 1-4
Transmission shaft 1-3 is rotated clockwise, and external screw thread transmission shaft 1-3 can drive linkage block 1-2 to move downward when rotating clockwise,
To drive rectangle door body 1-1 in the inside slide downward of center through slot 2-1 by linkage block 1-2, the closing of overhead door 1 is realized
Work, conversely, electric pushrod 3-1 drives the first rack gear 3-4 to slide to the left in the inside of runner frame 3-5 by push-and-pull connecting rod 3-3
When a certain distance, the unlatching work to overhead door 1 may be implemented；The resistance cigarette hermatic door 4 when in use, as rectangle door body 1-
When 1 slide downward, inflation mechanism 4-2, sealing door body 4-3 and rubber block air bag 4-4 rectangle door body 1-1 drive similarly hereinafter
Step is moved downwards, and inflation mechanism 4-2 can be inflated work under the action of the second rack gear 4-1 during moving downward
Make, the gas inside inflation mechanism 4-2 is poured to rubber to the inside for blocking air bag 4-4, to block air bag 4-4 by rubber
With the close contact of wall or doorframe, the blocking to smog is realized, and play the effect of resistance sound sound insulation；Conversely, working as rectangle door body
When 1-1 upward sliding, inflation mechanism 4-2, sealing door body 4-3 and rubber block air bag 4-4 under the drive of rectangle door body 1-1
It synchronizes and is moved upwards, inflation mechanism 4-2 can be evacuated during moving upwards under the action of the second rack gear 4-1
Work, so that the gas that rubber blocks the inside of air bag 4-4 is drawn back into inflation mechanism 4-2, so that rubber be made to block gas
Disengaging for capsule 4-4 and wall or doorframe, is convenient for shutter door work；The inflation mechanism 4-2 when in use, inflator
When structure 4-2 is moved downward, rotation gear 4-2-1 is rotated counterclockwise under the action of the second rack gear 4-1, rotates gear 4-2-
1 can drive the first worm screw 4-2-2 to be rotated counterclockwise when rotating counterclockwise, the first worm screw 4-2-2 drives the first worm gear 4-
2-3 is rotated counterclockwise, and the first worm gear 4-2-3 drives external screw thread control-rod 4-2-4 to be rotated counterclockwise, external screw thread control
Bar 4-2-4 drives lifting pressing plate 4-2-5 to carry out extruding work upwards in the inside of expansion box 4-2-6, so that passing through air injection pipe 4-
2-7 is injected into the gas inside expansion box 4-2-6 can be under the pressure effect of lifting pressing plate 4-2-5 through appendix 4-2-8
It enters to rubber to block in air bag 4-4, so that rubber be made to block the close contact of air bag 4-4 and wall or doorframe, realize to cigarette
The blocking of mist；Conversely, rotation gear 4-2-1 carries out suitable under the action of the second rack gear 4-1 when inflation mechanism 4-2 is moved upwards
Hour hands rotation, it is final to drive lifting pressing plate 4-2-5 slide downward in expansion box 4-2-6, so that rubber blocks the interior of air bag 4-4
The gas in portion is drawn back into expansion box 4-2-6, so that rubber is made to block disengaging for air bag 4-4 and wall or doorframe,
It is convenient for shutter door work；When in use, when a fire, control electric pushrod 3-1 is by pushing away for the fire protection flame retarding door 5
Draw connecting rod 3-3 that the first rack gear 3-4 is driven to slide into right end on the inside of runner frame 3-5, it is described when the first rack gear 3-4 is slided
The tooth of first top surface rack gear 3-4 left end can drive second gear 5-12 to be rotated counterclockwise, the first rack gear 3-4 and the second tooth
When taking turns 5-12 contact, the tooth of the first trailing flank rack gear 3-4 right end is separated with linkage gear 3-6, and second gear 5-12 turns counterclockwise
Third wheel shaft 5-11 and first pulley 5-9 can be driven to be rotated counterclockwise when dynamic, first pulley 5-9 can when rotating counterclockwise
To drive the second belt wheel 5-10 to be rotated counterclockwise by belt, the second belt wheel 5-10 can drive second when rotating counterclockwise
Worm screw 5-6 is rotated counterclockwise, and the second worm screw 5-6 can drive the second worm gear 5-5 to be turned counterclockwise when rotating counterclockwise
Dynamic, the second worm gear 5-5 can drive first gear 5-3 to be rotated counterclockwise when rotating counterclockwise, and first gear 5-3 is counterclockwise
