Description

Multiple functional door lock with spherical handle

The utility model relates to a kind of door lock with doorbell, double knock and dual fail-safe effect.

At present, mostly popular door lock is the dual fail-safe type, also has the different burglar-proof alarm door lock of various structures, but mostly these alarm door locks are to be used from several structures such as lock stamen, password and button etc. and key.In case get wrong but weak point is owner oneself, also can give the alarm.In the course of time will nap.Meeting for another example forces open the door also can not send out alarm when pounding lock, the family expenses doorbell is also mostly to be independent installations.

Fig. 2 is the A-A ' line sectional view of Fig. 1

Fig. 3 is the B-B ' line sectional view of Fig. 1

Below in conjunction with accompanying drawing the utility model is described in further detail:

Its outward appearance of the utility model Fig. 1 has a lock body (15) similar to the common double insurance lock for being outer spherical handle (1) and outer handle lining (22) in portion outdoors in, handle (13) in being equipped with on lock body.Its internal construction is for being equipped with circlip type lock stamen cover (2) in the outer spherical handle, lock stamen (4), and the two-sided jump ring sheet (3) that goes out spring, after key inserts the lock stamen, the jump ring sheet is tightened up, groove, the lock stamen in the reed release lock stamen cover is promptly rotatable at this moment, driving lock stamen cauda (6), slow-action bar (7), sliding piece (11) and shift fork (8) rotates, sliding panel (10) is dialled to the enable possition, and holddown spring (21) drives dead bolt (16) lock is opened.Lock stamen cover (2) in the outer handle fastens as one with outer handle (1), when outer handle is twisted, lock stamen cover (2) rotates simultaneously, at this moment lock stamen (4) because the effect of slow-action bar (7) is also rotated thereupon, but owing to the effect of two symmetrical position limiting slide blocks (24) up and down that has among Fig. 2, lock stamen cover can only be rotated in less angular range, and the angle of this rotation is by the spring on the position limiting slide block (25) control, and the angle of this rotation can not make a unlatching.When outer handle by (left, to the right all can) lock stamen cover after twisting in the side on top two protruding points are arranged handle lining (22) inside outside, contact on the doorbell microswitch (5) is pressed, pressing microswitch is connected, and music door-bell is played, and reports the someone and calls at the door.

When outer handle is pounded or is prized, at this moment lock the inevitable destruction of stamen cover and produce displacement with outer handle,

The opposite side on lock stamen cover (2) interior top handle lining (22) inside outside has the contact of a projection, has broken away from warning microswitch (23), makes pressure move the switch connection alarm from declining and gives the alarm.

Be lined with a L shaped steel disc (20) as Fig. 3 in lock bolt sleeve (17) inboard, individual the facing directly of one inserted doorframe inside, and another is faced directly with lock bolt sleeve and joins, and it connects hole (26) and is oval.In the dead bolt trepanning, there is a plate washer (18) to be pressed on the contact of alarm switch (19), when the people forces open the door, pounds the door and hits, lock bolt sleeve produces slip owing to be subjected to bump, at this moment plate washer (18) also slides simultaneously, no longer suppress on the contact of warning microswitch (19), make pressure from the moving switch connection that declines, give the alarm.

In the spherical handle (13), interior handle (13) can freely be opened door by shifting shaft (12) in door in sounder-loudspeaker of the present utility model (14) were contained in.(9) be circuit part, music door-bell of the present utility model and alarm circuit are to adopt the use that links of common music door-bell and warning device and microswitch.

The utility model is owing to having adopted the double-safety door lock, so still keep former dual fail-safe performance.Moreover, because being lined with, the lock bolt sleeve inboard inserts the L shaped steel disc of doorframe, make that lock bolt sleeve is stressed to have increased by three times.

Above structure has promptly constituted most preferred embodiment of the present utility model.

The utility model has the advantages that its outward appearance elegance is magnificent, rational in infrastructure, safety performance is strong, and has the five functions such as music door-bell, double knock, dual fail-safe at a door lock.
