Description
Technical field
The utility model relates to fire-fighting domain, particularly relates to a kind of normally closed normally opened automatics of safety door.
Background technology
Safety door at passageway for fire apparatus, under ensureing be held in its normally closed position in the case of not using, all can install certainly
Dynamic pass closed system (door closer).Existing door closer is the most all to utilize spring reset, and the time length of use, spring is old
Change, door closer will be made to lose effectiveness, safety door even can be made because of the damage of door closer to open hard.Once there is fire
Feelings, such safety door can have a strong impact on escape speed.
Summary of the invention
The purpose of this utility model is to provide a kind of normally closed normally opened automatics of safety door, naturally drooping by weight, plays
Pulling the effect of door leaf, enable safety door door leaf to be automatically switched off, service life is long, safe and reliable.It addition, at safety door
Upper installation alarm light, when there is the condition of a fire, escape personnel promotes door leaf that warning lamp can be made frequently to flash frequently, thus
Cue is sent for trapped personnel at a distance.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of normally closed normally opened automatics of safety door, including doorframe, door leaf, weight, fixed pulley, pulley fix seat, stay cord,
Alarm light, described door leaf is hinged with doorframe by hinge, and fixed pulley is fixed seat by pulley and is fixed on doorframe, stay cord
One end be connected with door leaf, stay cord enters and walks around fixed pulley from doorframe, and the other end connects weight, is also equipped with on doorframe
Alarm light.
Described alarm light includes gear wheel, little gear, small generator, wire, warning lamp, gear shaft hinge, tooth
Wheel shaft hinge is hinged between door leaf and doorframe, and Large Gear Shaft is fixing with the axle of gear shaft hinge to be connected, gear wheel and little gear
Engaging each other, be in transmission connection, pinion shaft is fixing with the power shaft of small generator to be connected, and small generator is by wire even
Connect warning lamp.
Described gear shaft hinge includes hinge fan, hinge axle sleeve, hinge axis, and hinge axle sleeve is socketed in outside hinge axis, with conjunction
Page shaft clearance coordinates, and hinge axis is connected with door leaf by hinge fan fixed thereon, and hinge axle sleeve is by fixed thereon
Hinge fan is connected with doorframe.
Compared with prior art, the beneficial effects of the utility model are:
A kind of normally closed normally opened automatics of safety door, naturally drooping by weight, play the effect pulling door leaf, make safety
Every fan can be automatically switched off, and service life is long, safe and reliable.It addition, install alarm light on safety door, sending out
During feelings of lighting a fire, escape personnel promotes door leaf that warning lamp can be made frequently to flash frequently, thus sends for trapped personnel at a distance and carry
Show signal.The warning lamp not used time does not consume electric energy, is to be generated electricity by natural power during use yet, saves the energy.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, it should be noted that enforcement of the present utility model
It is not limited to following embodiment.
As shown in Figure 1-Figure 3, a kind of normally closed normally opened automatics of safety door, including doorframe 1, door leaf 5, weight 2, determine to slide
Wheel 3, pulley fix seat 6, stay cord 4, alarm light, and described door leaf 5 is hinged with doorframe 1 by hinge, fixed pulley 3
Fixing seat 6 by pulley to be fixed on doorframe 1, one end of stay cord 4 is connected with door leaf 5, stay cord 4 from doorframe enter and around
Crossing fixed pulley 3, the other end connects weight 2, is also equipped with alarm light on doorframe 1.
During enabling, Manual-pushing door leaf 5, door leaf 5 is opened, and pulls stay cord 4 by weight 2 pull-up simultaneously.After people walks, draw
Rope 4 pulls door leaf 5 under the Action of Gravity Field of weight 2, makes door leaf 5 naturally close.
Described alarm light includes gear wheel 7, little gear 8, small generator 9, wire 10, warning lamp 11, gear
Axle hinge, gear shaft hinge is hinged between door leaf 5 and doorframe 1, and Large Gear Shaft 7-1 is solid with the axle 7-2 of gear shaft hinge
Fixed connection, gear wheel 7 engages each other with little gear 8, is in transmission connection, and pinion shaft is solid with the power shaft of small generator 9
Fixed connection, small generator 9 connects warning lamp 11 by wire 10.
Described gear shaft hinge includes that hinge fans 7-4, hinge axle sleeve 7-3, hinge axis 7-2, and hinge axle sleeve 7-3 is socketed in conjunction
Outside page axle 7-2, with hinge axis 7-2 matched in clearance, hinge axis 7-2 is by hinge fan 7-4 fixed thereon and door leaf 5
Connecting, hinge axle sleeve 7-3 is connected with doorframe 1 by hinge fan 7-4 fixed thereon.
It is connected owing to the axle 7-2 of gear shaft hinge is fixing with door leaf 5, therefore when promoting door leaf, fixes with hinge axis 7-2 and be connected
Large Gear Shaft 7-1 can concomitant rotation, drive gear wheel 7 rotate, gear wheel 7 drives little gear 8 to rotate, little gear 8
Export power to small generator 9, promote small generator 9 to send electric energy to warning lamp 11, make warning lamp 11 flash.
When there is the condition of a fire, people flee from from safety door one after another, and while promoting door leaf 5, warning lamp 11 will flash,
Now can be at a distance or be in the people got lost in smog and send bearing signal.
Alarm light is by sending electric energy from heat power, thus without the waste energy.
