In order to save space in lock housing, so that described release control assembly 4 can stackedly arrange with described release shifting part 404, on described release control assembly 4, form and take the second arc groove 116 that described latch release shaft 107 is the center of circle, described the 4th axle 405 is arranged in described lock housing 2 through described the second arc groove 116.
The described driving mechanism that lock out is one to be arranged on and to lock out biasing member 117 between described lock housing and described bolt plate, described in lock out 117 pairs of described bolt plate 5 of biasing member and impose the biasing force that lock out direction towards described dead bolt 1.The described biasing member that lock out can be preferably torsion spring.
The course of work of interior door lock of the present utility model:
Automatic locking process
While locking a door, triggering wheel bumps against with doorframe, make to trigger in frame 200 retraction lock housings 2, the contact triggering on frame 200 touches release control assembly 4, and release control assembly 4 is clockwise rotated around latch release shaft 107, in the draw-in groove 106 of the dop 108 that makes release control assembly 4 bolt plate 5, exit, the locking of releasing to bolt plate 5, now, locking out under the elastic force effect that reset bias piece is torsion spring of pressurized, bolt plate lock out automatically, and realization is locked.Trigger frame 200 and reset under the i.e. effect of the reduction torsion spring in figure of the first reset bias piece 203,, under the i.e. effect of the reset tension spring in figure of contact the second reset bias piece 204, reset meanwhile.If need locking states be insured, can rotate by key band movable lock core shifting part 401, then drive lock core safety plate 101 to clockwise rotate until the joint portion 102 on lock core safety plate 101 be hooked on described safety lock bonding part 103.
The process of unblanking
While opening the lock with the key, key band movable lock core shifting part 401 clockwise rotates, stir lock core safety plate and overcome the i.e. active force of the double jump torsion spring in figure of lock core safety plate biasing member 104, rotate counterclockwise, make joint portion 102 103 separated dropouts from lock core limited section, the release of lock core safety plate, lock core shifting part 401 is rotated further, by with bolt plate on the first integrated structure 400 bolt plate is towed back in lock housing, thereby realize, unblank.
While unblanking with handle, must first with key, lock core safety plate be opened, then clockwise rotate handle axle, handle shifting part 301 clockwise rotates with handle axle, setting due to idle running groove on handle safety plate 303, now, handle safety plate 303 is not driven, handle shifting part 301 is stirred release shifting part 404 and is rotated counterclockwise around the 4th axle, release shifting part 404 is in the process rotating counterclockwise, drive the second integrated structure 403 in bolt plate, drag in bolt plate retraction lock housing, now, the dop of release control assembly 4 snaps in draw-in groove 106 under the i.e. effect of the reduction torsion spring in figure of release biasing member 109, realization is unblanked.
After unblanking, need to keep closing the door but do not lock state time, can be by rotating counterclockwise handle axle 300, on handle axle, 300 square shaft promotes 303 rotations of handle safety plate, biasing force at handle safety plate reset bias piece 305, handle safety plate withstands release control assembly 4, and the dop 108 of release control assembly cannot be deviate from from draw-in groove 106, thereby will close the door but the state of not locking locks.At closing time, doorframe is encountered triggering wheel, make to trigger in frame retraction lock housing, because release control assembly 4 is locked, therefore, release control assembly is greater than the i.e. pulling force of reset tension spring in figure of the second reset bias piece 207 to the conflict power at structure of contact terminal place, now, structure of contact terminal can clockwise rotate, and makes described trigger architecture just maybe can not touch described release control assembly 4, and now contact lost efficacy.
When needs are removed handle insurance, only need clockwise direction to rotate handle axle and drive handle safety plate 303 counter-rotation, handle safety plate resets under the effect of handle safety plate reset bias piece 305.
Obviously, above-described embodiment is only for example is clearly described, not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And among the protection domain that the apparent variation of being extended out thus or change are still created in the utility model.
