Description

A kind of retaining mechanism of lockset

Technical field

The utility model belongs to lockset, is specifically related to a kind of retaining mechanism of lockset.

Background technology

The locking function of lockset all is that the movable part by its retaining mechanism cooperates with corresponding fixed part and realizes.The movable part of the retaining mechanism on the lockset generally includes and the dead bolt of lock core or handle interlock, locking bar etc.Fixed part is lock ear or fixed object.As the dead bolt that is installed on the door matches with lock ear on being installed in doorframe, perhaps dead bolt, locking bar directly with establish doorframe on lockhole match.Generally speaking, the locking of the retaining mechanism of mechanical lock or unlatching are controlled by lock core.Because the raising of skilled unlocking level, the thief patronizes indoor incident of committing theft and happens occasionally.The theftproof performance of therefore existing lockset is more and more challenged and is queried.Aspect antitheft, have only a kind of situation can make thief's skilled unlocking at one's wit's end, Here it is locks lock at the indoor locking member that utilizes, and makes retaining mechanism stuck, controlled by lock core or handle.But this mode only limits to indoor, can't realize outdoor.

The utility model content

The purpose of this utility model is to provide a kind of retaining mechanism of lockset, adopts outdoor also can the realization of being locked in of this retaining mechanism to lock, thereby improves the theftproof performance of lock.

The technical scheme that realizes the utility model purpose is: the retaining mechanism of lockset comprises movable part, the locking device with lock core or handle interlock; Locking device comprises extensible member, with the driver part of extensible member interlock, remote control receiving-member that is electrically connected with driver part and their power supply unit; Described movable part is provided with jog, and locking device is located at the position that adapts with movable part, and the extensible member on it can match with the jog on the movable part.

Driver part in the described locking device is a micromachine, and it matches with tooth bar on being located at extensible member by gear and realizes interlock.

Described extensible member is an inserted link.

Jog on the described movable part is hole, through hole, groove, breach etc., perhaps is projection, lug etc.

Described locking device can be installed in the lock body, also can be installed in outside the lock body.

Operating principle of the present utility model

Lock of the present utility model is housed behind outdoor locking,, drives the motion of extensible member inserted link and match, movable part is locked with jog on the movable part dead bolt (or locking bar) by the machine operation of locking device in the remote controller operation control lockset.At this moment, although can lock core be opened, because the locking of the extensible member of the locked device of movable part in the retaining mechanism still can't be opened lock by skilled unlocking.Because locking device is installed in the lock body or lock body outer (being positioned at indoor), the thief can't destroy again.This situation is equivalent to from indoor lock be locked.When unblanking, only need press remote controller, the counter-rotating of control motor drives the movable part that extensible member withdraws from retaining mechanism, gets final product by normally unblanking again.

The utility model can remote control locking device combine with the retaining mechanism of existing lock, realized the purpose that also can lock from outdoor, improved the theftproof performance of lock greatly.

The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

Embodiment 1

See Fig. 1, the retaining mechanism of lockset comprise with lock core in the movable part dead bolt 6 and the locking device of shift fork 21 interlock; Locking device comprises extensible member inserted link 8, inserted link 8 is provided with tooth bar 11, tooth bar 11 is fixed on the lock body 15 by bearing 9, be fixed with gear 10 in the rotating shaft 12 of driver part micro machine 13, gear 10 matches with tooth bar 11, micro machine 13 is connected with receiver of remote-control sytem 18 and battery 17 by lead 14, and receiver of remote-control sytem 18 and battery 17 are contained in the element storehouse 16; Dead bolt 6 is provided with through hole 7, and locking device is located at the top of dead bolt 6 in the lock body 15, and the inserted link 8 on it can match with the through hole 7 on the dead bolt 6; Dead bolt 6 is installed on the lock body 15 by support component 19, and shift fork 21 is provided with return spring 20.

In the door lock shown in Figure 1, under retaining mechanism of the present utility model, also be provided with handle mechanism, handle cooperates with shift fork 3 on the door bolt 1 by finger 22, finger 22 is spacing by backing pin 4, shift fork 3 is fixed on the lock body 15 by shifting fork pin 5, door bolt 1 is supported on the lock body 15 by support 23, and door bolt 1 is provided with return spring 2.Turning handle can drive door bolt and seesaw, and plays the effect of under unlocked situation door being located.

The use of lock after locking, is pressed the close push button on the remote controller 24, and after receiver of remote-control sytem 18 received signals in the lock body, control micro machine 13 rotates, and drives inserted link 8 and moves downward in the through hole 7 that stretches on the dead bolt 6 dead bolt 6 lockings; When unblanking, press releasing the button on the remote controller 24, after receiver of remote-control sytem 18 received signals, control micro machine 13 backward rotation drive inserted link 8 and move upward, and withdraw from the through hole 7 from the dead bolt 6, can normally unblank.
