Describe details and the working condition of complying with the Electronic card door lock that the utility model proposes in detail below in conjunction with accompanying drawing.

This Electronic card door lock has adopted the combining form of electronic card and magnetic core card.Electronic circuit 49 devices of electronic section are in wainscot 50, and card reader 48 is arranged in the outer panels 3, has electronic card socket 4 on the outer panels 3.In backplate shell 25 and lock core shell 29, install leaf spring 23, backplate 21, cover plate 20, lock core 27, backplate 21 and cover plate 20 form the socket of magnetic core cards 1.The outside of cover plate 20 is equipped with jam plate 22, has several apertures on the jam plate 22, and the small magnetic rod that is contained on the magnetic element in the lock core 27 can insert in it.Driving shaft 24 is installed at the middle part of lock core 27, utilizes pin 39 that drive block 40 and lock core 27 are combined as a whole, and symmetrical two pin-and-holes are arranged on the drive block 40, and drive pin 37 can be according to the actual needs of left and right opening door, in one of them pin-and-hole of packing into.Return spring 31 and reverse pin 30 are housed in the blind hole of lock core 27, and backplate shell 25 and lock core shell 29 usefulness screws 28 tighten together it, are fixed in the outer panels 3 with screw 51 again.Rotary shaft rack 26 usefulness screws 47 are fastened on the lock core shell 29, and the rotating shaft 35 of tape spool cover 36 is housed on it, and an end of rotating shaft 35 is installed shift fork 38, one ends shifting block 32 is installed, and shift fork 38, shifting block 32 usefulness pressure pads 33 and screw 34 are fastening.Fixed axis 41 rivetings are contained on the lock core shell 29, fastening usefulness when this lock is installed.The slow-witted tongue 5 that has a special-shaped groove is installed in the groove on the lock housing 42, so that it can move left and right.Slow-witted one of tongue shifting block 19 usefulness are installed on the lock housing 42, and its end has square shaft, and square shaft is packed into and stayed in the special-shaped groove of tongue 5.End that connect to dial plate 45 is fixed on the lock housing 42, and an end links to each other with slow-witted tongue shifting block 19, the middle part by bearing pin be connected arm-tie 44 connections.One end of connection arm-tie 44 is dialled plate 8 by bearing pin and movable lug and is connected.The rear end of movable lug 6 is provided with a major axis, is with a spring on the major axis, and it passes the hole that movable lug is dialled plate 8, and is fixed with Spring Card, and front end passes lock housing 42.The anti-tongue 7 of dialling is installed on the lock housing 42 by a fixed head, it can be on fixed head move left and right.Anti-shifting block 18 is installed on the lock housing 42 by a vertical shaft.Movable dialling on the plate 8 is equipped with a fixed reset axle 46, and it matches with anti-shifting block 18, and there is a major axis anti-rear end of dialling tongue 7, is with spring on it, so that the anti-tongue 7 of dialling resets.

Electromagnet 9 is made up of two coils 14 and iron core 43, and it is in permanent magnet 12 is contained in an iron-clad and be fixed in the lock housing 42.Magnet axle 13 penetrates in coil 14, the iron core 43.Permanent magnet 12 is inhaled on iron core 43, is that magnet axle 13 is magnetized with the effect of permanent magnet 12.The end that electromagnetism is dialled plate 11 is fixed on the end of magnet axle 13, and a part contacts with shifting block axle 15, a part ofly contacts with shifting block 32.Shifting block 10, shifting block cover 17 are installed on the lock housing 42, two square shafts that are connected with handle 2, and one of them penetrates in the shifting block cover 17, and one penetrates in the shifting block 10.Spring 16 and shifting block axle 15 are housed in the hole of shifting block 10, and spring 16 can make shifting block axle 15 reset.The lower end of lock housing 42 is provided with the battery case that power supply is installed.

When utilizing this lock to lock a door, as long as door is shut, movable lug 6 inserts in the latch plate of door limit, i.e. locking under the effect of spring.At this moment, because shifting block axle 15 is not pressed in the shifting block 10, when rotating handle 2, handle 2 dallies in shifting block 10, and movable lug 6 can't move, and can not open.

Originally be locked in inner plate surface 50 and be provided with a hand that slow-witted tongue 5 is stretched out and turn round, therefore can utilize on hand turns round door lock indoor.

When opening this lock, electronic card is inserted in the socket 4, electronic circuit 49 is connected, electric current moves magnet axle 13 by coil 14, and drives electromagnetism and dial plate 11 shifting block axle 15 is pressed in the shifting block 10, and shifting block 10 and shifting block 17 are fused, at this moment, rotate handle 2, handle 2 drives shifting block cover 17 and shifting block 10 rotates, and shifting block 10 is stirred movable lug and dialled plate 8, movable lug is dialled plate 8 drive movable lugs 6 and is moved, movable lug 6 is given up the throne, and withdraws from the latch plate of door limit, and lock is promptly opened.If slow-witted tongue 5 is in locked position, when rotating handle 2, movable lug is dialled plate 8 and is just driven connection arm-tie 44, connects and dial plate 45 motions, connects group plate 45 and stirs slow-witted tongue shifting block 19, and slow-witted tongue shifting block 19 is stirred slow-witted tongue 5, and it is return in the latch plate of door limit, and lock i.e. unlatching.

When circuit does not have electricity or breaks down, available magnetic core card 1 inserts between backplate 21, the cover plate 20, when the coding of the magnetic element in the coding of magnetic core card 1 and the lock core 27 matches, lock core 27 is moving linearly upwards in lock core shell 29 just, the driving shaft 24 at lock core 27 middle parts, pin 39 drive drive block 40 motions, drive pin 37 on the drive block 40 drives shift fork 38 and sways, the shifting block 32 that is contained in the rotating shaft other end also rotates thereupon, and the drive electromagnetism is dialled plate 11 motions, shifting block axle 15 is pressed in the shifting block 10, at this moment rotates handle 2 locks and can open.

When transfering to magnetic core card 1, lock core 27 resets under the effect of reverse pin 30 and backspring, and at this moment drive pin 37 drive shift forks 38 and shifting block 32 reset, and the leaf springs 23 in the backplate shell 25 reset backplate 21 simultaneously.

This lockset has the anti-mechanism of dialling.The anti-tongue 7 of dialling is pressed at closing time, drives anti-shifting block 18 simultaneously and rotates, and an end of anti-shifting block 18 blocks movable lug 6 just, and it can not be retreated, and just can prevent that lockset from being pushed aside by the people this moment on the door lock.

When using this Electronic card door lock, only open this lock usually with electronic card.Only when having electricity or break down, electronic circuit just do not open this lock with the magnetic core card.
