Description
(1) technical field
The utility model belongs to a kind of positioner that opens the door of safe-guard door lock, specifically is the size that this device can limit a unlatching, and the chamber owner can be talked with the outsider, and the outsider can't the interior device of inlet chamber.
(2) background technology
Along with Chinese national economy continues, stable, healthy development, living standards of the people have had large increase, and valuables are on the increase in the family, and the antitheft consciousness of people generally strengthens, and makes security door come into huge numbers of families, but still feels safety inadequately.Because also there is harm social security in present stage, seriously disturb the law-breaker of resident's normal life.Deceive the chamber owner in every way as the offender and open the door, and take this opportunity to swarm into indoor crime.One metal zip fastener generally is set between door and doorframe at present, makes door can only open certain position and prevent in lawless person's inlet chamber, but this mode, poor safety performance, very not attractive in appearance, and use inconvenient.
(3) summary of the invention
The technical problems to be solved in the utility model provides an a kind of security door that makes door can only the be opened to desired location location lock that opens the door.
The technical scheme that adopts
Security door opens the door and locatees lock, comprises positioner and locking device.
Positioner is installed in the doorframe lock body.Positioner comprises lock body shell, ratchet, plane scroll spring, safety line (other flexibly connect to comprise chain etc.) and ratchet alignment pin.Side at ratchet shaft is set with back-up ring, and an end of safety line is fixed on the ratchet shaft between ratchet and the back-up ring, and is wrapped on the ratchet shaft, and the other end of safety line is set with the backstay that has latch recess.Plane scroll spring is located on the ratchet shaft, and its outer end is fixed on the spring base, and ratchet, plane scroll spring, back-up ring all are contained in the lock housing body.Ratchet alignment pin jack is arranged on the housing, and the ratchet alignment pin can insert in the housing by this jack, and can pass spring base and replace on the setting ratchet of ratchet.Be set with back-moving spring on the ratchet alignment pin, an end of back-moving spring is replaced on housing, and its other end is replaced on spring base.
Locking device is installed in the upper lock body, and locking device comprises clamp and connecting rod, and an end of connecting rod is connected by bearing pin with clamp, and the lock core coupling of the other end and safe-guard door lock connects, and can spur connecting rod by screw key and move forward and backward.Be equiped with torsion spring on the clamp axle, the two ends of two legs of torsion spring are stuck on each binding clip of clamp, make clamp be in closure state.Be provided with the backstay jack on door upper lock body shell, backstay inserts in the clamp of locking device by the backstay jack, can not withdraw.
The straight section part that the above-mentioned safety line that is connected with backstay stretches out can change the telescopic lever structure into, interior bar one end of telescopic lever connects backstay, other end attachment security rope, safety line twists on the ratchet shaft by pulley, and telescopic lever can be compressed in the lock body shell at closing time.Other structure is identical, constitutes telescopic lever formula positioner; The straight section part of stretching out can also change four-bar linkage structure into, four link rod heads connect backstay with bearing pin, and pole one end of afterbody is fixed on the connecting rod base, and the other end connects with safe rope and twists on the ratchet shaft by pulley, other structure is identical, constitutes the telescopic positioner of four connecting rods.
Reclaim the backstay of safety line and connection slowly for safety, the utility model has disposed deceleration device, the square toes place of twining ratchet shaft one end of safety line inserts deceleration device gear square opening, speed brake setting is on the doorframe lock body shell, and when safety line reclaimed, plane scroll spring spurred the ratchet shaft fast rotational, drive deceleration device middle gear quick rotation, with the gear shaft quick rotation of gears engaged, the worm gear quick rotation above the mounting teeth wheel shaft, rotate with the worm gear engaged worm.Worm screw one side is provided with fixed friction sheet bearing support, one end of friction plate bearing support stretches in the dead turn, be contained in friction plate on the friction plate bearing support near on the dead turn, because of friction makes worm speed-down, worm gear reducer like this, gear shaft slows down, gear reduction, the ratchet shaft that connects on the gear slows down, and therefore the safety line that is entangled on the ratchet shaft affects backstay slowly to reclaim.
Security door opens the door to locate to lock and also is provided with backstay compression set pin, be on the doorframe lock body shell, to have set pin-and-hole, the compression set pin is packed into by pin-and-hole in the housing, suit back-moving spring on the compression set pin, replace on compression set pin and lock body shell, backstay leans on the pulling of safety line when the door delocalization, in the backstay retraction lock housing, press the compression set pin when door is located, backstay just can eject.
During use
1, call at the door as the people, house-owner people assert when needing to start positioner, promotion compression set pin, and the backstay in this device ejects, and by flexibly connecting, connects doorframe and door when opening the door.Open the door distance when meeting the demands when the chamber owner thinks, press the bottom ratchet wheel alignment pin, then flexibly connect fixed-site.
2, when need open the door, open the door internal lock with key (consistent) with the key that opens the door, then flexibly connect withdrawal, door is opened.
3, when need at closing time, make the backstay release, the door can close.
4, think that as owner messenger need not set the location of opening the door, not according to the compression set pin, then backstay does not eject, the delocalization of opening the door.
The utlity model has advantages such as rational in infrastructure, easy for installation, easy to use quick, safe and reliable, be suitable for vast family security door and use.
