Door state induction pieces 24 are mounted on the lower groove layer 212 of guide rail 21, by main circuit inductive component 25 and shutdown state inductive component
26 are separately mounted to the both ends of guide rail 21.In this way, completing the assembly of door closer 2.
Figure 14, Figure 16 are please referred to, fire resistant doorsets are now in closed state, and sliding block 22 is located at the shutdown state sense of door closer 2
One end of component 26 is answered, the induction pieces 222 of sliding block 22 incude shutdown state inductive component 26, and main circuit board 252 can receive cunning
Position signal of the block 22 in shutdown state inductive component 26, fire fighting monitoring center real time monitoring fire prevention door state.At this point, sliding block is locked
The state of locking mechanism 23 is that locking structure 233 is flexibly pressed against on the warpage end 312 of return block 31, the hump of contact shoe 41
411 is prominent not from 231 upper surface of mounting base, the unadsorbed electromagnetism of magnet absorbing plate 34 on the electromagnet absorption end 314 of return block 31
Iron 234.
Figure 15, Figure 17 are please referred to, fire resistant doorsets are in enabling maintenance state, and sliding block 22 is located at the door opening state sense of door closer 2
One end of part 24 is answered, induction pieces 222 and door opening state induction pieces 24 incude, and main circuit board 252 can receive sliding block 22 and open the door
The position signal of state inductive component 24.
Figure 14, Figure 16 and Figure 17 are please referred to, when fire resistant doorsets are from closing to opening, external force pushes, and thrust overcomes hydraulic press 3
Maintenance shutdown direction power, fire resistant doorsets open under the effect of external force.Sliding block 22 slides into door opening state sense along upper groove layer 211
It answers on part 24, the induction pieces 222 and door opening state induction pieces 24 of sliding block 22 incude, and main circuit board 252 receives sliding block 22 and opening
The position signal of door state induction pieces 24 issues instruction, and electromagnet 234, which is powered, adsorbs magnet absorbing plate 34, drives the electricity of return block 31
Magnet adsorbs end 314 and swings around pin shaft 32 towards electromagnet 234, corresponding, and the warpage end 312 of return block 31 is towards locking structure
233 swing, and warpage section 312 holds cap 43 to top and exerts a force, and hump 411 is prominent from locking hole 208, and hump 411 supports sliding block 22 and returns cunning,
By 22 locking of sliding block, in this way, realizing when opening automatically to the locking of fire exit door, the opening state of fire exit door is maintained.Going out
When existing fire-fighting dangerous situation, external cigarette sense or temperature detector detect set for closing fireproof door signal transmission after dense smoke enters passageway for fire apparatus
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 under the action 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 under the action of hydraulic press 3 along track 21 to shutdown state sense
Answer component 26 mobile, sliding block 22 slides into the top of shutdown state inductive component 26, and induction pieces 222 incude, fire fighting monitoring center
Can real-time awareness fire exit door be in shutdown state.
When cigarette sense or temperature detector failure need promptly to close, then the urgent push switch of Manual press is only needed
2521, urgent push switch 2521 sends a signal to main circuit board 252, and main circuit board 252 issues demagnetization letter to electromagnet 234
Number, so that the hump 411 of contact shoe 41 be made to retract in locking hole 208, the electromagnet of return block 31 adsorbs end 314 to mounting base
231 upper surfaces are swung, and the warpage end 312 of return block 31 is then swung to 231 lower surface of mounting base, work of the sliding block 22 in hydraulic press 3
With lower to the mobile closing for realizing fire resistant doorsets of shutdown state inductive component 26.
To sum up, electromagnet of the door closer 2 of the present invention by the way that the sliding block lockable mechanism 23 is arranged, in sliding block lockable mechanism 23
Magnet absorbing plate 34 on the electromagnet absorption end 314 of 234 absorption return blocks 31, so that electromagnet be made to adsorb end 314 towards electromagnet
234 swing, and the warpage end 312 of return block 31 is swung towards locking structure 233, and then exerts a force to make to touch to locking structure 233
The hump 411 for putting seat 41 is prominent from 231 upper surface of mounting base, supports to sliding block 22, to form oneself after fire resistant doorsets open the door
Dynamic locking.The present invention utilizes lever force-saving principle, is designed by reasonable structure, door closer 2 is only with 1 lesser electricity of power consumption
Magnet dramatically saves electric energy, and it is 1:3 that the warpage section 312 of return block 31 and the length of swing arm main paragraph 311, which are selected, is led to
It crosses return block 31 and is installed on swing arm slot formation lever, reach labour-saving effect, effectively extend the service life of electromagnet.
Without departing from the thought of the invention, any combination is carried out to various different embodiments of the invention, it should all
