Detailed description of the invention:
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, two ratchet buffering door closer, includes housing and is fixed in oil buffer 2, electrical control mechanism 3 and the ratchet trigger mechanism 4, figure on base plate 1 and omit housing.Oil buffer 2 rotating shaft 21 one end is fixed with actuating arm of closing the door, the other end is fixed with ratchet 22, ratchet 22 both sides are respectively equipped with the first ratchet 23 and the second ratchet 24, first ratchet 23 and the second ratchet 24 axle are positioned on the front panel 11 of base plate 1, namely also front panel 11 is erect and is fixed on base plate 1, is used for electrical control mechanism 3 and ratchet trigger mechanism 4; Described first ratchet 23 and the second ratchet 24 are exerted all one's strength by the first spring 25 be located on front panel 11 and the second spring 26 respectively, keep the trend of conflicting all the time on ratchet 22.
Described electrical control mechanism 3, comprises electromagnet 31 and pin rod 32, and this pin rod 32 links with electromagnet 31, and one end and the ratchet trigger mechanism 4 of pin rod 32 link; More particularly, pin rod 32 is formed by band iron right-angle bending, and right angle end and electromagnet 31 are fixed together, and electromagnet between the shell of this end and electromagnet 31 is arranged with back-moving spring 33.
Described ratchet trigger mechanism 4, comprises drive plate 41, hand lever 42, frizzen 43 and large torsion spring 44; Drive plate 41 slides and is sticked at front panel 11 medial surface, and its one end is fixed with protruding pin 411, middle part has a groove 412, the other end has the first contact part 413 and the second contact part 414; First contact part 413 is conflicted on the first ratchet backing pin 231, conflict in the second contact part 414 on the second ratchet backing pin 241, synchronously triggers the first ratchet 23 and the second ratchet 24 opening action by described drive plate 41; Described large torsion spring 44 is positioned on front panel 11, and toggle is conflicted at described protruding pin 411 rear portion, drive plate 41 is remained open the trend of the first ratchet 23 and the second ratchet 24; Described hand lever 42 axle is positioned on front panel 11, and conflicting in the front portion of described protruding pin 411 in bottom, drives described drive plate 41 to overcome the torsion of large torsion spring 44 and retreat by this hand lever 42, forms energy accumulating state; Described hand lever 42 upper end swings backward, can touch pin rod 32, form the interlock of action backward, so that people is for closing door operation, also namely returns to swinging door state; Described frizzen 43 lower end axle is positioned on front panel 11, the interior knuckle 431 of bottom can tangle on the groove 412 in the middle part of drive plate 41, pin the position of drive plate 41, upper end and the pin rod 32 of frizzen 43 link, also namely pin rod 32 upper end offers slotted eye 322, the short pin 432 of frizzen 43 upper end, through described slotted eye 322, forms the interlock of frizzen 43 and pin rod 32.Electromagnet 31 obtains electric, adhesive is toward inside contracting, pull this pin rod 32, frizzen 43 is driven to swing, remove the locking to drive plate 41, drive plate 41 produces displacement under large torsion spring 44 spring-force driven dual, the first ratchet 23 and the second ratchet 24 is backed down, ratchet 22 loses restriction, and oil buffer 2 drives door leaf to complete closing motion.
Further, this drive plate 41 is formed by iron plate punching, and middle part has elongated slot 415, and described groove 412 is located at upside in this elongated slot 415; The interior knuckle 431 of frizzen 43 stretches in described elongated slot 415, and the groove 412 that can tangle upside forms locking, and does not take redundant space.
Described first ratchet 23 one-tenth L structures, upper end axle is positioned on front panel 11, first ratchet backing pin 231 is located at corner, first spring 25 is little torsion spring, be positioned on front panel 11, its toggle is conflicted at the first ratchet 23 back, makes the first ratchet 23 press to trend on ratchet 22 all the time around axle anchor point; Described second ratchet 24 one-tenth structures of falling L, corner's axle is positioned on front panel 11, second ratchet backing pin 241 is located at bottom, described second spring 26 is little torsion spring, be positioned on front panel 11, its toggle is conflicted at the second ratchet 24 back, makes the second ratchet 24 press to trend on ratchet 22 all the time around axle anchor point; Be less than described first spring 25 and the second spring 26 with joint efforts the torsion of large torsion spring 44, make easily to open ratchet.
With reference to Fig. 3, for door closer normally off, also namely drive plate 41 forms conflict to two ratchet simultaneously, two ratchets are opened, and all remove the constraint to ratchet 22, door leaf is driven by oil buffer 2 all the time, be in and close door state, inlet/outlet is for open immediately, and automatic closed condition, also namely as spring door structure; Fig. 4 is door closer normally open, and artificially manually drive plate 41 retreats by bar 42, removes drive plate 41 and retrains the conflict of two ratchets, two ratchets, when each torsion spring effect from childhood, press to ratchet 22 in good time, are in energy accumulating state, and door leaf is similar to common door, can freely open and close; When emergency rating occurs, can be long-range by electrical control mechanism 3, realize the Long-distance Control needs that multiple door leaf closes door simultaneously.Or artificial manually bar 42 swings backward, drive pin rod 32 to retreat, pull frizzen 43, remove and drive plate 41 is retrained, realize manually closing an action, return to swinging door state.For this reason, pin rod 32 can be provided with pin 321 or similar lug boss etc., can touch when hand lever 42 swings backward, drive pin rod 32 to retreat; Or be provided with salient point at hand lever 42 rear portion, the right angle end of pin rod 32 rearward end can be touched.
