Specific embodiment
Refer to accompanying drawing 1-2.
Burglary-resisting window fire auto-unlocking device of the invention, it is solid in the side of heat conducting disk 1 with the heat conducting disk 1 that metal is made
Surely there is temperature-sensing pipe 2, the one end of temperature-sensing pipe 2 is closed by heat conducting disk 1, another end opening；There is temperature-sensitive chamber 12, in temperature-sensitive in temperature-sensing pipe 2
Temperature-sensing element 3 is provided with chamber 12, the one end of temperature-sensing element 3 is fixedly connected in heat conducting disk 1, and the other end is fixedly connected with expansion link
5, expansion link 5 is rotatably coupled one end of lever 6；With rotatable support shaft 7 as fulcrum, the other end of lever 6 leads to lever 6
Cross rotary shaft 8 and be rotatably coupled pull bar 9, pull bar 9 is fixedly connected pin 10；Pin 10 passes through logical on burglary-resisting window rivet 11
Hole, burglary-resisting window 13 is fixed on wall 14.
Described temperature-sensing element 3 has a thermal conductive metal pipe 19, and the one end of thermal conductive metal pipe 19 is closed by heat conducting disk 1, separately
One end is provided with airtight piston 4, and thermal conductive metal pipe enclosure portion is surrounded air chamber 18 by piston 4, has solid in the inner sealing of air chamber 18
Quantitative air；Piston 4 is fixedly connected expansion link 5；Barrier sheet 16 is provided with the described opening of thermal conductive metal pipe 19.
Teeth 17 are provided with described expansion link 5；When expansion link 5 is moved, teeth 17 can through barrier sheet 16 but
Can not return.
The opening of insertion ambient atmosphere and air chamber 18 is provided with described heat conducting disk 1, is open by low-melting alloy piece 15
It is closed.
Heat-conducting silicone grease is filled with described temperature-sensitive chamber 12.Described heat conducting disk 1 is integrally formed with temperature-sensing pipe 2.
In use, the present invention is installed according to said structure, heat conducting disk 1 is disposed in the interior, for example room
In interior walls.During generation fire, burglary-resisting window rivet 11 is fixed by pin 10, and burglary-resisting window 13 is fixed on wall 14, can
Play good anti-theft effect.When indoor generation fire, due to the effect of thermal current or flame, indoor temperature is raised, heat conduction
The temperature of disk 1 rises, and conducts to temperature-sensing pipe 2, temperature in temperature-sensitive chamber 12 is increased, and then cause the temperature of temperature-sensing element 3 to rise.Sense
Warm element 3 drives expansion link 5 to move, and the work lifting rod 9 for passing through lever 6, by pin 10 from burglary-resisting window rivet 11
Extracted in through hole.The locking of burglary-resisting window rivet 11 is released from, and can directly extract, and now burglary-resisting window can easily to outdoor overall
Pull down.As fire is not serious, fire is extinguished that rear burglary-resisting window rivet 11 is not pulled out, burglary-resisting window is not removed, then above-mentioned mistake
Journey is reversed, and pin 10 will be reinserted in the through hole on burglary-resisting window rivet 11.Burglary-resisting window rivet 11 is retightened, and burglary-resisting window can
To be continuing with.
The operation principle of temperature-sensing element 3 described in the present embodiment is as follows：
During the general fire of generation, temperature rises in temperature-sensitive chamber 12, and the temperature of thermal conductive metal pipe 19 rises therewith.Heat-conducting metal
The one end of pipe 19 is closed by heat conducting disk 1, and the other end is provided with airtight piston 4, and thermal conductive metal pipe enclosure portion is surrounded gas by piston 4
, there is the air of fixed amount room 18 in the inner sealing of air chamber 18, and the air themperature that this is closed also rises therewith.Air pressure after atmosphere temperature rising
Increase, outer push piston 4 simultaneously drives expansion link 5 to move.When piston 4 is moved at the opening of thermal conductive metal pipe 19, can be blocked
Piece 16 stops, with Anti-extrusion thermal conductive metal pipe 19.
When inside fire than it is more serious when, for avoid because fire-fighting and rescue reduction indoor temperature, burglary-resisting window is lockable again,
Need permanently to release the fixation of burglary-resisting window rivet.The setting of teeth 17 can realize the function.When temperature rise to it is default
Risk altitude when, because expansion link 5 is moved to the direction for stretching out thermal conductive metal pipe 19, teeth 17 will through barrier sheet 16 but not
Can return.Now barrier sheet 16 is stuck between piston 4 and teeth 17, limits the motion of expansion link 5 and piston 4, finally makes pin
Nail 10 keeps the state extracted from the through hole on burglary-resisting window rivet 11.Even if indoor temperature decreases, pin 10 is still not
In turning back to the through hole on burglary-resisting window rivet 11.
During in order to prevent inside fire extremely serious, because there is strong temperature in fire-fighting and rescue (such as spray water, spray dry ice etc.)
Difference reduces indoor temperature, and negative pressure is excessive and destroy barrier sheet 16 in air chamber 18, burglary-resisting window is lockable again, and the present invention sets
The opening of insertion ambient atmosphere and air chamber 18 is equipped with, is open closed by low-melting alloy piece 15.Temperature is too high indoors, teeth 17
Through after barrier sheet 16, stop because piston 4 is blocked piece 16, cause pressure rise in air chamber 18.High temperature and elevated pressure
Cause low-melting alloy piece 15 to melt jointly to penetrate.Now the sealing structure of air chamber 18 is destroyed, gas and the external world in air chamber 18
Air is directly connected, no matter indoor temperature how to change will not the both sides of piston 4 formed draught head, pin 10 be permanently in from
The state extracted in through hole on burglary-resisting window rivet 11.Even if during fire-fighting, because the reasons such as water spray make indoor temperature rapid
So it is down to normally, burglary-resisting window rivet 11 still will not be fixed again, facilitates the broken window rescue of fire fighter or survivor broken at any time
Window is escaped.
In addition, being filled with heat-conducting silicone grease in temperature-sensitive chamber 12, temperature-sensing element 3 can be made to heat up rapidly, acted sensitiveer.Lead
Hot plate 1 is integrally formed with temperature-sensing pipe 2, more uniformly can promptly conduct heat, the present invention is obtained superior technique effect.
The present invention does not use any spring members, effectively prevent spring undergoing the compression of long period, stretch or receive
Elastic force is lost after thermal annealing, the situation for causing burglary-resisting window to open.The present invention does not use any electronic circuit apparatus yet, can be with
Prevent electronic circuit apparatus in fire from having a power failure, short circuit or break down and loss of function, cause burglary-resisting window to open.
