The transverse slat gib block on the body of heater front wall at left and right sides of fire door is put, offers transverse slat guide groove on transverse slat gib block, transverse slat is led
To the notch of groove towards upper cross plate and lower cross plate；The left and right ends of upper cross plate and the left and right ends of lower cross plate are connected to transverse slat
Guide plate, corresponding to the insertion of transverse slat guide plate in transverse slat guide groove.
It is simple in construction that the associated mechanisms of fire door are lifted in the utility model, is easily installed and operates.If lift fire door
Suspend fire door top in midair, then the power transmission shaft of lifting device needs to set very high, could be still higher than after fire door upwardly opens
At the top of fire door, castering action can be just played.When fire door is lifted in the utility model, suspended in midair by chain lifting mechanism in fire door
The left and right sides of bottom, therefore i.e. fire door is flush or even slightly above power transmission shaft after upwardly opening with power transmission shaft, can still rise
To effective castering action.So, the utility model be reduced by the space taken, convenient installation and overall construction intensity compared with
It is past to be improved.
When fire door lifts, transverse slat guide groove is served spacing by transverse slat guide plate, upper cross plate and lower cross plate to fire door
Effect, make process that is door opened and closing more stable.
