Description
Technical field
The present invention relates to insertion-core lock, the latch bolt mechanism of specific design insertion-core lock.
Background technology
Insertion-core lock is also mortise door lock, is typically made up of handle, lock core, the part of lock body three, installed in indoor sleeved door, prevents
Steal in the majority on door, be also one of most common lockset on the market.Existing insertion-core lock mainly includes single slow-witted tongue insertion-core lock, single-bolt
Button insertion-core lock and double tongue insertion-core locks, wherein double tongue insertion-core locks are provided with slow-witted tongue and latch bolt, its anti-theft more singly stays tongue insertion-core lock
High with single-bolt button insertion-core lock, the function according to handle can be divided into single insertion-core lock, dual-active insertion-core lock living and open insertion-core lock soon again,
It is easy to use.
But existing insertion-core lock can not be locked, it is necessary to use key or rotation outer door handle ability automatically after closing the door every time
Stretch out main dead bolt and realize lock function, insertion-core lock uses more inconvenience.
The content of the invention
The present invention is regarding to the issue above, it is proposed that a kind of latch bolt mechanism of insertion-core lock.Solve after existing insertion-core lock closes the door
Can not lock automatically, it is necessary to key or rotation outer door handle main dead bolt can just stretch out, insertion-core lock uses more inconvenience
Problem.
The technical scheme that the present invention takes is as follows：
A kind of latch bolt mechanism of insertion-core lock, the insertion-core lock includes lock housing, and latch bolt mechanism includes：
Latch bolt component, is slidably arranged in the lock housing；
Latch bolt back-moving spring, in lock housing, for applying outside active force to latch bolt component, makes the latch bolt group
Lock housing is stretched out at the tongue end of part；
Triggering tongue component, is slidably arranged in the lock housing, and the glide direction for triggering tongue component is slided with the latch bolt component
Dynamic direction is identical；
Triggering tongue back-moving spring, in lock housing, for applying outside active force to triggering tongue component, makes described touching
Lock housing is stretched out at the tongue end for sending out tongue component；
Trigger, is slidably arranged in the lock housing；
Trigger reset spring, in lock housing, for applying active force to trigger, makes trigger to perpendicular to oblique
The direction movement in tongue component slippage direction；
The latch bolt component has latch bolt confined planes, and the trigger has for being offseted with the latch bolt confined planes, makes
After lock housing is stretched out at the tongue end of latch bolt component, the first auxiliary section for no longer being pushed back in lock housing；The trigger is pressed towards trigger
During back-moving spring, the first auxiliary section departs from the latch bolt confined planes；
The triggering tongue component has a projection, the trigger have stretch into the triggering tongue component tongue end and projection it
Between the second auxiliary section；Lock housing is stretched out at the tongue end that the projection is used to be pressed towards trigger reset spring and triggering tongue in trigger
When, offseted with second auxiliary section, trigger is remained the state for pressing to trigger reset spring.
In the application " when trigger is pressed towards trigger reset spring ", refer in the presence of external force, trigger is received
Power is moved to trigger reset spring, and trigger reset spring is compressed.
The structure type of the application causes that triggering tongue component is pressed into lock housing so that projection and second at closing time
Mating part is from while latch bolt component auto-extending lock housing in the presence of latch bolt back-moving spring, last trigger reset, first
Auxiliary section and latch bolt confined planes, latch bolt component are locked；And can also be interlocked with other mechanisms of insertion-core lock during trigger reset,
Control other mechanism actions.
Further, the latch bolt that the latch bolt component includes latch bolt seat and is rotatably installed on latch bolt seat end.
Further, the latch bolt is Bidirectional oblique flap.
The applicability for being designed to increase insertion-core lock of Bidirectional oblique flap, you can in the environment of L.H.flapped door, also may be used
With according in the environment of R.H.flapped door.
Further, the latch bolt seat has a recess away from the side of latch bolt, and the recess sidewall is limited for the latch bolt
Plane.
Further, first auxiliary section include with the recess sidewall coordinate the first side wall and with the recess
The second sidewall that bottom wall coordinates.
This structure type can be such that latch bolt seat preferably coordinates with the first auxiliary section, increase the reliability of mechanism.
Further, the triggering tongue component includes triggering tongue contiguous block and is rotatably installed on triggering tongue contiguous block
Triggering tongue.
Further, the triggering tongue contiguous block has a straight side walls, and the projection is located at straight side walls away from triggering
The side of tongue；When the trigger is not pressed towards trigger reset spring, the second auxiliary section offsets with the straight side walls.
This structure type can be such that triggering tongue contiguous block preferably coordinates with the second auxiliary section, increase the reliability of mechanism
Property.
Further, the latch bolt back-moving spring is torsion spring, stage clip or extension spring；The triggering tongue back-moving spring is torsion
Spring, stage clip or extension spring；The trigger reset spring is torsion spring, stage clip or extension spring.
Further, there is multigroup chute, the latch bolt component, triggering tongue component and trigger have in the lock housing
There is the sliding block for stretching into correspondence group chute.
The beneficial effects of the invention are as follows：The structure type of the application causes that triggering tongue component is pressed into lock housing at closing time
It is interior so that projection and the second mating part are from while latch bolt component auto-extending lock in the presence of latch bolt back-moving spring
Shell, last trigger reset, the first auxiliary section and latch bolt confined planes, latch bolt component are locked；And can be with during trigger reset
Other mechanisms with insertion-core lock interlock, and control other mechanism actions.
