The position signalling of door state induction pieces 24, instruction is sent, electromagnet 234, which is powered, adsorbs magnet absorbing plate 34, drives the electricity of return block 31
Magnet adsorption end 314 is swung around bearing pin 32 towards electromagnet 234, corresponding, and the warpage end 312 of return block 31 is towards locking structure
233 swing, and warpage section 312 exerts a force to cap 43 is held, and hump 411 protrudes from locking hole 208, and hump 411 supports sliding block 22 and returns cunning,
By the locking of sliding block 22, in this way, realizing when opening automatically to the locking of fire exit door, the open mode of fire exit door is maintained.Going out
During existing fire-fighting dangerous situation, outside cigarette sense or temperature detector detect dense smoke into behind passageway for fire apparatus, the transmission of set for closing fireproof door signal
To main circuit board 252, main circuit board 252 stops powering to electromagnet 234, and electromagnet 234 stops absorption magnet absorbing plate 34, return block
31 electromagnet absorption end 314 is swung up in the presence of return spring 33, the warpage end 312 of return block 31 to lower swing,
The hump 411 of contact shoe 41 is retracted in locking hole 208, and sliding block 22 is in the presence of hydraulic press 3 along track 21 to shutdown state sense
Component 26 is answered to move, sliding block 22 is slipped into the top of shutdown state inductive component 26, and induction pieces 222 sense, fire fighting monitoring center
Can real-time awareness fire exit door be in shutdown state.
When cigarette sense or temperature detector failure need urgent close, then only need Manual press promptly by compressing switch
2521, promptly 2521 send a signal to main circuit board 252 by compressing switch, main circuit board 252 sends demagnetization letter to electromagnet 234
Number, so that the hump 411 of contact shoe 41 is retracted in locking hole 208, the electromagnet of return block 31 adsorbs end 314 to mounting seat
231 upper surfaces are swung, and the warpage end 312 of return block 31 is then swung to the lower surface of mounting seat 231, work of the sliding block 22 in hydraulic press 3
With the lower closing that fire resistant doorsets are realized to the movement of shutdown state inductive component 26.
To sum up, the utility model door closer 2 is by setting the sliding block lockable mechanism 23, the electricity in sliding block lockable mechanism 23
Magnet 234 adsorbs the magnet absorbing plate 34 on the electromagnet absorption end 314 of return block 31, so that electromagnet adsorbs end 314 towards electricity
Magnet 234 is swung, and the warpage end 312 of return block 31 is swung towards locking structure 233, so to locking structure 233 force so as to
The hump 411 of contact shoe 41 is protruded from the upper surface of mounting seat 231, sliding block 22 is supported, after forming fire resistant doorsets enabling
Automatic locking.The utility model utilizes lever force-saving principle, and by rational structure design, door closer 2 is only with 1 power consumption
Less electromagnet, electric energy is dramatically saves on, and the warpage section 312 of return block 31 and the length of swing arm main paragraph 311 are selected
For 1:3, swing arm groove is installed on by return block 31 and forms lever, reaches labour-saving effect, effectively extend electromagnet uses the longevity
Life.
