Abstract

The utility model relates to a contact device of a door lock. The contact device comprises a trigger frame, a trigger structure, a contact structure and a first resetting bias pressing piece, wherein the contact structure is provided with a trigger effective state and a trigger failed state on the trigger frame; the trigger effective length of the contact structure in the trigger failed state is shortened to a state that the trigger structure is completely retreated in a panel relative to the trigger effective length of the contact structure in the trigger effective state, the contact structure exactly does not or cannot touch an unlocking control component; when the effect of a second resetting bias pressing piece to the contact structure is greater than the counter effect of the unlocking control component to the contact structure, the contact structure is rotated or moved from the trigger failed state to the trigger effective state; when the effect of the second resetting bias pressing piece to the contact structure is less than the counter effect of the unlocking control component to the contract structure, the contract structure is rotated or moved from the trigger effective state to the trigger failed state. The contact device has the advantage that when the door lock is in an unlocking security state, the contact device automatically loses efficacy, and collision noise is not caused.

Description

A kind of contact apparatus of door lock

Technical field

The utility model relates to door lock field, specifically a kind of contact apparatus of controlling the control assembly in automatic door lock bolt extending control mechanism.

Background technology

At present, automatically the lock out mechanism of mechanical lock after unblanking is suggested, and automatically lock out in mechanism existing, is all provided with the actuating device of bolt extending control mechanism, lock out motion for further controlling dead bolt member.Chinese patent literature CN201362993Y discloses a kind of actuating device that lock out control assembly in control structure, has along the actuator lever of the panel direction setting perpendicular to lock housing and for making actuator lever complete the reset biasing member resetting after control action; Actuator lever is pivotally mounted in lock housing by a fulcrum; Actuator lever comprises actuating contact, integrated structure and releasing structure.In use procedure, at closing time, when the door leaf of door lock contacts with doorframe, the one end with roller that protrudes from the actuator lever of panel contacts with doorframe, actuator lever is that the plane of door leaf moving parallel is interior around a spot wobble, drives the shoulder type parts that originally deviated from control assembly to be meshed with control assembly.In the time that roller further enters between doorframe and door leaf, doorframe thrust roller also overcomes the biasing force of biasing member, makes actuator lever drive control assembly to vertically move, and makes control assembly control the action of associated components, stretch out thereby control dead bolt member, complete the process of locking.

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, remove the locking 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 joint portion on lock core safety plate 101 102 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 separate and thread off from lock core limited section 103, 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, due to the setting of 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 keep close the door but do not lock state time, can be by rotating counterclockwise handle axle 300, on handle axle, 300 square shaft promotion handle safety plate 303 rotates, at the biasing force of 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.

In the time that 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 without also giving exhaustive to all embodiments.And among the protection domain that the apparent variation of being extended out thus or variation are still created in the utility model.
