Abstract

An electronically controlled lock adds a mechanical tapered end on an electronic cipher lock. A crank of the mechanic tapered end is connected with an unlocking mechanism of the electronic cipher lock. In addition, an armature of a small electromagnet seizes the crank of the mechanic tapered end under the power-on condition thereby the crank is unable to work on the unlocking mechanism. Under current-off condition, keys can be used to unlock the door so as to save the reserve power supply.

Description

A kind of electric control door lock

The utility model relates to safe-guard door lock and household door lock, relates in particular to the antitheft electric control door lock of electronic cipher.

Existing various safe-guard door lock generally all is to adopt mechanical lock head, the friction when opening of the pellet shot from a slingshot of tapered end and key causes wearing and tearing, make the tapered end inefficacy and can not use (be 60,000 the application life of national Specification tapered end), and for public security door, with 16 families, eight floor rooms, each household 4 people, unblank to count for 2 times for each person every day, accumulating unlocking was above 46000 times in 1 year, therefore the mechanical lock head on the security door is very short service time, because tapered end damages, resident family has home whereto one cannot go, and has caused many troubles and contradiction.Existing people has proposed various electronic password locks, and they all are by after the decoding circuit decoding usually, touch electromagnet, unblank by electromagnet armature effect unlocking mechanism.No matter be to adopt mechanical lock, still adopt electronic password lock, the security door of residential building all is the mode that adopts electric controlled door, can unblank by connecting circuit by the people of premises like this.Because these electric control door locks can not use when having electricity, therefore tend to be furnished with a cover standby electric power (electronic password lock is more wanted so), cause the cost (or cost of electric controlled door) of lock to greatly increase.And about 2～3 years of application life of battery commonly used in the standby electric power, general resident family is difficult in time find also to change, and has often increased many troubles.

The purpose of this utility model provides a kind of electric control door lock, and it adopts electronic password lock, unblanks with existing various wireless remote control decodings or wired artificial button decoding or the like mode, can open the lock with the key when having a power failure.Therefore can dispose standby electric power, reduce cost, easy to use, reliable.

The purpose of this utility model is achieved in that a kind of electric control door lock.Include the electronic cipher lock assembly, one mechanical lock head is installed on electric control door lock, crank on the mechanical lock head is connected with the unlocking mechanism of electronic cipher lock assembly, one little electromagnet is arranged in addition, little electromagnet armature blocks the crank of mechanical lock head when energising, make crank can not act on unlocking mechanism.Usually unlocking mechanism is divided into machine driving clamp mechanism and labella energy storage clamp mechanism, wherein the machine driving clamp mechanism comprises electromagnet armature, be stuck in the clamp in the armature groove, the main hyoplastron that drives by labella energy storage clamp mechanism etc., when not having electricity, the crank of mechanical lock head can act on electromagnet armature by sliding piece, electric control door lock is unblanked, also can directly act on armature, make it decontrol clamp, electric control door lock is unblanked, can also act on main hyoplastron directly or indirectly, electric control door lock is unblanked, and when electricity was arranged, little electromagnet is the direct crank-operated of limit mechanical tapered end both, also can limit crank-operated by the action of the restriction driving member (as sliding piece) that crank drove, can also can not exert an influence to unlocking mechanism when making crank-operated by cutting off the contact of crank, therefore can't when electricity is arranged, use key operated electric control door lock unlocking mechanism, this moment, electric control door lock must be unblanked with wireless remote control decoding or artificial button decoding, became an electronic password lock.When not having electricity, because little electromagnet dead electricity, its armature has been removed the influence to crank under the effect of spring, thereby make mechanical lock head can act on the unlocking mechanism of electronic password lock, this moment, electric control door lock became mechanical lock, can make to open the lock with the key, thereby when having electricity, still can not open electric control door lock, saved standby electric power, reduced cost, used also very convenient.

The utility model is further described during below in conjunction with accompanying drawing:

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the structural representation of an embodiment of the present utility model;

Fig. 3 is that the K of Fig. 2 is to view;

According to crank (2) being installed on Fig. 1 mechanical lock head (1), one little electromagnet being installed, there is a breach corresponding on the armature (3) on this little electromagnet with crank (2) on crank (2) next door.When electricity, little electromagnetic actuation armature (3) makes its breach block crank (2) just, crank (2) can not be rotated, thereby can't trigger unlocking mechanism; When not having electricity, little electromagnet loss of excitation, armature (3) armature (3) of under the spring action of little electromagnet, upspringing, thus make the breach of armature (3) leave crank (2), crank (2) can rotate, and unblanks by stirring unlocking mechanism.According to Fig. 2 and Fig. 3, electric control door lock has main tongue (4), main tongue (4) is installed on the main hyoplastron (7), main hyoplastron (7) is connected with labella energy storage clamp mechanism (5) by a slide plate, the clamp of labella energy storage clamp mechanism (5) is installed on the breach of clamp (6), the bottom of clamp (6) is stuck in the groove of armature (8) of electromagnet (9), two pin of armature (8) lower end bending are stuck on the breach on sliding piece (11) the right by pin (10), jagged and the recess in sliding piece (11) top, wherein the breach corresponding position has by coil (13), be installed in the iron core (14) in the coil (13), the yoke (15) of fixed coil (13), the armature (12) that is installed on the yoke (15) acts on the little electromagnet that the spring (16) on the armature (12) is constituted, the corresponding with breach of one outstanding position (19) and sliding piece (11) arranged on the armature (12), make that should give prominence to position (19) when electricity is arranged is stuck in the breach of sliding piece (11); There is mechanical lock head (1) the recess corresponding position, crank (2) on the mechanical lock head (1) falls into this recess when rotating, thereby can drive sliding piece (11) action (when not having electricity), there is pin (17) positioning and guiding on the left side of sliding piece (11), and and lock housing between locate to be equipped with top pressure spring (18).

When electricity is arranged, because armature (12) acts on and iron core (14) adhesive electromagnetic force, outstanding position (19) on the armature (12) falls into the breach of sliding piece (11), blocks sliding piece (11), makes the crank (2) on the mechanical lock head (1) can not stir sliding piece (11).Therefore can't work to the electric control door lock lock, can not open electric control door lock.

When electric control door lock does not have electricity, armature (12) is pull-up armature (12) under the effect of spring (16), make armature (12) go up outstanding position (19) and leave breach on the sliding piece (11), rotary machine tapered end (1) drove sliding piece (11) by crank (2) and moved to left this moment, thereby made armature (8) top swing (being equivalent to electromagnet (9) energising adhesive) to the right, make clamp (6) drop, the unlocking mechanism action makes main tongue (4) retraction lock housing, and this moment, electric control door lock was opened.

The utility model has replaced the standby electric power of electric control door lock with mechanical lock head, has reduced cost widely, and is simple in structure, easy to use, reliable.
