The linkage mechanism of the utility model enables the door lock to be quickly locked or unlocked and comprises, a lock bolt shifting rod, a diagonal bolt, a unidirectional turning block, a bidirectional turning block, a diagonal bolt shifting fork, a retaining slice torsional spring, a retaining slice, a drag plate, torsional springs, a shifting fork for the drag plate and a shifting fork for the retaining slice. The utility model is characterized in that a quick unlocking device, a quick locking device and an anti-picking device is respectively arranged in the linkage mechanism.
Description
Technical field
The utility model belongs to lock technology field, particularly a kind of link gear that is used for the quick locking of door lock, unlatching.
Background technology
Existing safe-guard door lock exists door lock and all needs when locking or unlatching with rotating the locking or the unlatching that could realize door lock in the keyhole on the key insertion door lock core, therefore use very inconvenience, particularly in case of emergency, its drawback is apparent especially, as when the indoor breaking out of fire, indoor occupant can not be withdrawn the scene of fire rapidly.
Summary of the invention
The utility model is existing above-mentioned at locking or when opening at existing safe-guard door lock, all need to insert and rotate the locking that to realize door lock or the drawback of unlatching in the keyhole on the door lock core with key, a kind of link gear that is used for the quick locking of door lock, unlatching is provided, this mechanism can make the quick locking of door lock and open fast, in case of emergency, as when the indoor breaking out of fire, make indoor occupant can withdraw the scene of fire rapidly.
The technical solution adopted in the utility model is finished in the following way: the link gear that is used for the quick locking of door lock, unlatching comprises locking bolt driving lever, oblique tongue, unidirectional switch block, two-way switch block, oblique tongue shift fork, retaining sheet torsion spring, retaining sheet, planker, torsion spring, planker shift fork and retaining sheet shift fork, wherein, the locking bolt driving lever is installed in the lock box, makes it to slide up and down; Planker shift fork folder is inserted in the middle of the U-shaped retaining sheet shift fork, by the reference column hinge on the lock box on lock box; One end hinge of torsion spring is at the top of planker shift fork, and other end hinge is on the retaining sheet lead; Planker is pressed on the planker shift fork, and the planker post on its middle carriage passes 7 font holes on the planker shift fork, the kidney slot on the lock box respectively; Retaining sheet is by on planker, and its middle carriage post passes the teeth groove of retaining sheet, and two retaining sheet leads are inserted in two kidney slots on the retaining sheet simultaneously; One end of retaining sheet torsion spring is against on the lock box, and the other end is hooked on the retaining sheet; Tiltedly tongue shift fork, two-way switch block, unidirectional switch block are installed in the dome hole on the lock box successively.
In said structure, form quick opening device by oblique tongue shift fork, two-way switch block, retaining sheet shift fork, planker shift fork, retaining sheet, locking bolt driving lever and planker.When the complete locking of link gear, make two-way switch block rotation at indoor rotation handle (in the direction of the clock), at this moment two-way switch block drives the retaining sheet shift fork and rotates, and retaining sheet is pulled down, and makes it to lose stopping function.When switch block continued motion, two-way switch block also drives when driving the rotation of retaining sheet shift fork: (1) planker shift fork rotated the planker translation, made main dead bolt withdrawal; (2) tiltedly the tongue shift fork rotates, and with oblique tongue translation, oblique gyrus lingulais is contracted; (3) the locking bolt driving lever moves down, thereby drives the locking bolt retraction, thereby finishes the emergency opening function, and outdoor, because of the effect of unidirectional switch block, and loses this function, reaches the outdoor purpose that can't open.
In said structure, form quick locking device by retaining sheet, planker, retaining sheet shift fork, planker shift fork, two-way switch block, unidirectional switch block.When main dead bolt is in opening, to rotate handle in indoor (or outdoor) and make the switch block rotation, a hook portion that fork is directly stirred retaining sheet of at this moment two-way switch block (or unidirectional switch block) forces retaining sheet to move down, and makes it to lose stopping function; Continue rotation, when a fork continues to stir retaining sheet and moves down, thereby another fork stir the planker shift fork and rotate and drive the planker translation, main dead bolt is stretched out, thereby finishes quick locking function in indoor (or outdoor).
In said structure, form pick-proof (retaining) device by torsion spring, planker shift fork, planker, when main dead bolt locking, the planker shift fork is under the effect of torsion spring, by 7 font holes with the planker post locking on the planker, planker can't be bounced back, have only when dialling commentaries on classics planker shift fork just to make the planker retraction, thereby reach tamper-resistant function.
The utility model is compared with the link gear on the existing safe-guard door lock, has the advantages that to make quick locking of door lock and unlatching, and it is very convenient to use, and especially works as indoor generation in emergency circumstances, can the energency-unlocking hedging.
