Description
Technical field
The invention belongs to door lock technical field, specially a kind of achievable left and right, the door of interior outward swinging door direction auto-changing
Lock.
Background technology
L.H.flapped door and R.H.flapped door are a concepts with handle-door lock, and L.H.flapped door is that door opener stands in front of the door, and door lock is in
Left-hand side；R.H.flapped door is that door opener stands in front of the door, and door lock is in right-hand side；Door-lock bolt mechanism generally use latch bolt, outward swinging door
When latch bolt inclined-plane is outwardly inwardly, during inward swinging door on latch bolt inclined-plane.Door lock manufacturing enterprise will often produce left outside door lock according to demand,
Four kinds of specifications are locked in left inside door lock, right external-open door lock, right inward swinging door；Needing to reequip the enabling direction right and left mutually changing of traditional lock body
When, generally require to unload handle, then some devices in housing are rotated or exchanged, layman has tended not to successfully
Installed into right and left mutually changing；When needing to reequip door lock to adapt to interior outward swinging door, it is necessary to which taking lock body apart exchanges the oblique of latch bolt.Dismounting
When the problem of part to be present excessive, and assembling is complicated, and cost is high.
In addition in order to improve the security that door lock uses, typically locked and positioned with locking pin on door lock, such is locked
The feed mechanism twice of tight mechanism and dead bolt integrates, and intermediate conversion part is more, and assembling is complicated, and cost is high, it is difficult to bears
Larger destructive power, and this kind of mechanism is driven by mechanical lock, is easy to technology unlatching, is unfavorable for the intelligent control of door lock, exists
The not true factor of secure context.
The content of the invention
For existing door lock has left and right, the exchange of interior outward swinging door direction is difficult, lock body assembling is complicated, it is unsuitable for intelligent control
The problem of processed, the present invention propose a kind of achievable left and right, the door lock of interior outward swinging door direction auto-changing.
The present invention it is achievable left and right, the door lock of interior outward swinging door direction auto-changing, including the casing mechanism of both sides and
The lock body mechanism at middle part, it is characterised in that：
Casing mechanism handle push rod, handle return spring, handle spring support, is held by housing, handle, handle return disk
Hand locating dowel forms, wherein：Handle bearing extends vertically through housing and is fixedly connected with the handle return disk in housing, handle return
Disk is hinged handle push rod, and bar-shaped trough is radially arranged along handle push rod；Handle locating dowel is set in housing above handle return disk, held
Be hinged handle spring support outside hand locating dowel；The bar-shaped trough of handle push rod is spacing by handle locating dowel and on handle spring support
In the perforate of matching slidably；Return spring is enclosed on handle push rod, is realized between handle return disk and handle spring support
It is flexible；
Lock body mechanism includes electric locking part and manual locking part, wherein：Electric locking part by motor, worm screw,
Locking spring, locking plate and locking spring support composition：Worm screw and motor connection, locking spring one end coordinate along snail with worm screw
Bar is moved axially, and the other end is hinged on locking spring support；Locking plate one end sets the latch segment of projection, and one end sets two
Limited post, locking spring pass through limited post；Locking spring support and locking plate middle part are coaxial by the locking plate rotating shaft between lock body
It is fixed；Manual locking mechanism includes straight tongue, straight tongue frame and straight tongue driver plate composition：Set on lock body shell and do straight line for straight tongue frame
Reciprocating bar shaped guide groove, straight tongue afterbody are fixedly connected with straight tongue frame；Set in straight tongue frame and the latch segment on locking plate
The stopper slot matched somebody with somebody, the interior setting of straight tongue frame and the locating slot that moving arm matches on straight tongue driver plate；Straight tongue driver plate center sets through hole to supply
Outside handle driving makes straight tongue driver plate move in a circle；
Through there is connecting rod in straight tongue driver plate through hole, connecting rod both ends are connected with handle respectively, can be driven by connecting rod
Dynamic lock body mechanism.
Locating piece top on described locking plate sets the projection more than stopper slot, the fortune downward for limiting locking plate
It is dynamic.
More preferably, lock body mechanism is vertically installed with world hook plate, and world hook plate stretches out the upper and lower part of bottom plate；Sky and ground hook
Middle part is obliquely installed bar-shaped trough in plate, tilts the world hook that bar-shaped trough is set along straight tongue frame and pulls post to slide；World hook plate two
End is vertically arranged bar-shaped trough；Vertical bar-shaped trough slides along the locating dowel between cover plate and bottom plate.
Described connecting rod is made of square steel.
During the door lock locking state, handle holding part is horizontal：To electrical power, motor driven worm screw rotates, worm screw band
Dynamic locking spring motion, locking spring driving locking plate enter locking state, now rotate straight tongue driver plate, and straight tongue driver plate drives straight
Tongue frame moves, and due to the stop of latch segment on locking plate, straight tongue driver plate is stirred arm contact locking plate and can not be rotated further, and straight
Tongue frame can not further retract, and now door lock is in released state.Continue firmly to rotate straight tongue driver plate, treat dialling for straight tongue driver plate
After swing arm damage, straight tongue frame can continue to retract, and can not continue behind the head of the limited impression contact locking plate of straight tongue frame afterbody
Retract, so as to realize that the two-stage of straight tongue frame is locked, improve reliable lock.
During the door lock released state：Give motor anti-phase energization, motor driven worm screw rotates backward, and worm screw drives locking spring
Motion, locking spring driving locking plate enter released state；Straight tongue driver plate is now rotated, straight tongue driver plate drives straight tongue frame movement,
Due to the stop of no locking plate, straight tongue driver plate can drive straight tongue frame to move to the state of being fully retracted into.Handle is pushed, compression
Handle return spring applies thrust to handle push rod, and handle is maintained at stable state vertically downward, and now straight tongue is completely maximum
In stroke retraction door body.
The achievable left and right of the present invention, the door latch structure of interior outward swinging door direction auto-changing are ingenious, and assembling is reliable, realizes
Left and right, interior outward swinging door direction auto-changing function while, employ electronic, manual secondary locking design concept, thoroughly
Solve traditional retaining mechanism and be easy to the potential safety hazard that technology is opened, is difficult to bear larger destructive power.
