One end of the state inductive component 42 of closing the door of door closer 100, one end and the button cap 4211 of sliding block 20 are supported (in hydraulic press effect
Under), the contact chip of status contacts switch 423 of closing the door described in the bottom pressure holding of sliding block 20, so that main circuit board 412 can receive cunning
Block 20 and is sent to fire fighting monitoring center (not shown) in the position signalling of the state of closing the door.Now, with reference to refering to Figure 16, sliding block
The state of lockable mechanism 30 is that the sliding block screens end of return block 32 is held by the elastic component 34, put on sliding block screens end to
Preset height, the contact seat bearing end of return block 32 is compressed to the frame hole 3122 of mounting seat, now, the gear laminate of return block 32
323 scratching part 3231 is in disengaged position with the hook 353 for holding piece 35, and the expansion link 362 of electromagnet 36 is in and stretches out shape
State, and piece 35 will be held support the state that erects (corresponding to the state held of mutually being hooked with scratching part 3231), hold the extension of piece 35
Hook 353 and support the bottom for being affixed on scratching part 3231.The spacer pin 3133 of contact shoe 331 is supported on the top of vertical shift pilot hole 3113,
Disk roller 335 is gone up groove layer 12 and is slightly protruded relatively.
Push opening fire exit door when, the thrust of outside opposite house overcomes the maintenance of hydraulic press to close the door the power in direction, and fire exit door exists
Opened in the presence of external force, sliding block 20 slides into the sliding block screens end of return block 32 along upper groove layer 12, when being moved to contact shoe 331
Hump 3313 when, sliding block 20 pushes hump 3313, then slides on disk roller 335 and push disk roller 335, and disk roller 335 is assisted
Sliding block 20 is slipped into sliding block screens end.As sliding block 20 is slided, fire resistant doorsets are opened completely, and sliding block 20 slides into the gear of return block 32
In laminate 323, one end of sliding block 20 offsets with domatic the 3232 of gear laminate 323 and pushes gear laminate 323, under gear laminate 323
Move, the scratching part 3231 of gear laminate 323 is squeezed to support and holds piece 35, and the expansion link 362 of electromagnet 36 is compressed, and refers to Figure 17, gear pressure
After body 323 moves down certain distance, the hook 353 for holding piece 35 is snapped in the gear scratching part 3231 of laminate 323, and expansion link 362 stretches out,
In this way, hold piece 35 held laminate 323 is kept off, and prevent the sliding block screens end of return block in the presence of the elastic component 34 on put.
When keeping off laminate 323 and moving down, i.e. the sliding block screens end bottom, contact seat bearing end will correspondingly upper pendulum, contact the roller of holder assembly 33
Move and protrude out in upper groove layer 12 on wheel 335, in this way, blocking sliding block 20 in the presence of the power of state is closed the door in the maintenance of hydraulic press
Disk roller 335 is slipped over, sliding block 20 is spacing in the sliding block screens end of return block 32, in this way, when fire exit door is opened, can be automatically real
Fire exit door is held after opening now, the state of checking card of fire exit door is maintained, now, gear laminate 323 compresses door opening state sensing
Part 43, fire fighting monitoring center can real-time awareness fire exit door be in door opening state.
When there is fire-fighting dangerous situation, outside smoke sensing sensor senses dense smoke into behind passageway for fire apparatus, then transmission is closed
Gate signal to main circuit board 412, main circuit board 412 sends actuating signal to electromagnet 36, and electromagnet 36 is acted, electromagnet 36
Expansion link 362 is retracted and is stretched out under the action of the spring, and hook 353 and the gear laminate 323 of piece 35 are held when expansion link 362 is retracted
Scratching part 3231 be separated, gear laminate 323 in the presence of the elastic component 34 on bullet, in this way, the sliding block screens end of return block 32
Upper pendulum, the contact seat bearing end bottom of return block 32, disk roller 335 is gone up groove layer 12 and is declined relatively, effect of the sliding block 20 in hydraulic press
It is lower to slide onto one end of the state inductive component 42 of closing the door of track 10 and be the blocking of button cap 4211 by disk roller 335, prevent
Sliding block 20 skids off guide rail 10.The status contacts switch 423 of closing the door of state inductive component 42 of closing the door is compressed, fire fighting monitoring center can be real
Shi Zhixiao fire exit doors are in door opening state.
When smoke sensor failure needs urgent close, then it is urgent by compressing switch 4221 to only need to Manual press, promptly
4221 main circuit board 412 is sent a signal to by compressing switch, main circuit board 412 indicates electromagnet 36 to act, so as to discharge hold piece
36 pairs are kept off holding for laminate 323, are put on the sliding block screens end of return block 32, the contact seat bearing end bottom of return block 32, sliding block
20 slip over the closing that disk roller 335 realizes fire resistant doorsets.
To sum up, the utility model door closer is by setting the sliding block lockable mechanism 30, the return of sliding block lockable mechanism 30
Gear laminate 323 is set on block 32, and gear laminate 323 has domatic 3232 so that one end of sliding block 20 supports, and pushes gear laminate
323, after gear laminate 323 is moved down, i.e. the sliding block screens end bottom, contact seat is put on bearing end, and the projection of disk roller 335 is kept off to sliding block 20
Hold, so realize holding automatically after fire resistant doorsets enabling.By in the top surface of plate body 3311 of contact holder assembly 33, hump is set
3313, can stably blocking sliding block 20, and set in the bottom surface of plate body 3311 and move down spacing section 3317, can efficiently control and connect
The space put on touch base bearing end, sliding block cunning is through disk roller 335 when preventing excessively upper pendulum and being unfavorable for opening the door.Additionally, electrical connection sense
Answer in component 40 and be arranged on the middle part of guide rail 10 by by main circuit board 412, state sense group of closing the door is set at the two ends of guide rail 10
The power supply terminal 44 in end cap 50 at one end is installed in part 42, door opening state induction pieces 43, the connection of door opening state induction pieces 43,
Circuit connection is simple, and the state opened the door or close the door can be accurately sensed in real time.
