Description

3-way electronic cipher lock without mechanical contact

The utility model belongs to a kind of electronic password lock, is particularly suitable for the device of installing and using on the various doors of higher antitheft and reliability requirement.

Existing electronic lock has overcome mechanical lock can not prevent saw, dial, sled, stifled, weakness such as master key, has the password height, good confidentiality, do not carry advantages such as key, but also there is the not high problem of reliability, disclosed Chinese patent application 91205878.8 is owing to adopted the element that mechanical contact is arranged in the circuit, for example: the mechanical cipher keyboard, relay, travel switch, brush motor etc., mechanical contact in these elements is because air pollution, aging, electric spark, factors such as wearing and tearing, very easily produce loose contact and cause lockset malfunctioning, thereby reduced reliability and application life.

The purpose of this utility model provides a kind of no mechanical contact Three-bearing electronic password lock, and it can prevent to cause because of the mechanical contact loose contact reduction in reliability and life-span effectively.

The purpose of this utility model is achieved in that with induction type 12 bit keyboards input proper password, master element SR301 will export a control signal of 2 seconds, drive the low-voltage direct electromagnet, make the electromagnetism ratchet break away from it stuck horizontal dead bolt, rotate handle and can open the horizontal dead bolt of rack-and-pinion, open dead bolt up and down by two mesomerism gears simultaneously.When shutting, backward rotation handle to the first gear, the electromagnetism ratchet is failure to actuate, and lockset is in the Inner door lock state, does not have the password can be manually opened, goes to second gear, and the electromagnetism ratchet restores stuck dead bolt under the elastic force effect.

The utility model is not owing to contain mechanical contact in circuit, so performance is reliable especially, simultaneously, owing to adopt the stuck mechanism of electromagnetism ratchet and manual two grades of location Three-bearing dead bolts, it is big to make this lock not only overcome electronic dead bolt power consumption, easy to wear, weakness such as fault rate height, and have the Inner door lock function.Inductive keyboard has and touches the time-delay illumination functions, is beneficial to and opens night, also the mechanical keyboard on the equipment such as alternative telephone, governor circuit SR301 has 12 passwords, can compile 1,000,000,000 groups of passwords, three input error codes, reporting to the police 3 minutes, is replaceable password on keyboard.The normal use of lock when adopting non-maintaining automatic charge power supply to guarantee to have a power failure, when the cell degradation brownout, indicator lamp is lighted the prompting changing battery, the emergency machine tapered end makes the utility model more perfect, once automatically controlled part is malfunctioning, only need with the door of emergency machine tapered end correspondence position on, bore one 8 hole, there is key can open the electromagnetism ratchet, thereby door is opened.Emergent tapered end adopts Anti-drilling lock and the topping of anti-the brill is housed and warning device anti-drilling, the fire resistant cutting.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the electrical schematic diagram according to the nothing machinery contact Three-bearing electronic password lock that the utility model proposes.

Fig. 2 is the mechanical assembly drawing of this lock.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2 according to the concrete device that the utility model proposes.

Not having mechanical contact Three-bearing electricity gives coded lock and comprises a touch automatic delayed throw light on 12 bit keyboards (1), governor circuit SR301(2), delayed alarm and lighting circuit (3), automatically charge power supply (4), electromagnetism ratchet (5), horizontal dead bolt (6), two mesomerism gears (7), manually driving lever (8) by square bar (9) link to each other with inside and outside two handles, dead bolt (10) and emergency machine tapered end (11) up and down.

Horizontal dead bolt (6) is stretched out by the square hole on the lock housing (13), the common bound level dead bolt (6) of location column (14) in the long guide hole on this square hole and the horizontal dead bolt (6), can only do 20mm stroke linear reciprocating motion, location column (14) riveting is on lock housing (13).The installation of dead bolt (10) and horizontal dead bolt (6) adopt with a kind of mode up and down.Two mesomerism gears (7) are respectively by two axles (15) location of riveting on lock housing (13), and mesomerism gear (7) and horizontal dead bolt (6), the tooth bar on the dead bolt (10) meshes simultaneously up and down.Electromagnetism ratchet (5) is made up of electromagnet (16) and ratchet (17), riveting has phosphorus bronze sheet (18) on the armature of electromagnet (16), copper sheet (18) end has square hole, ratchet (17) is inserted in the square hole, ratchet (17) is fixing by the axle (19) of riveting on lock housing (13), and electromagnet (16) is fixed by bolts on the lock housing (13).Two coaxial circles boss on the driving lever (8) cooperate installation with the loam cake of lock housing (13) with two circular holes on the base plate respectively, and emergency machine tapered end (11) is fixed by bolts between the loam cake and base plate of tapered end (13), and keyhole has the topping of anti-the brill altogether.Spring location lock (12) is installed on two support plates that lock housing (13) base plate punching press leaks down.

When dead bolt (6), (10) when being in retracted mode, rotate counterclockwise handle driving lever (8) and make dead bolt (6,10) extend out to first grade, lock is in the Inner door lock state, can clockwise rotate handle without password and open.When rotating counterclockwise handle, dead bolt (6,10) extend out to second grade, electromagnetism ratchet (5) is stuck under the elastic force effect in the groove on the horizontal dead bolt (6), dead bolt (6) is in stuck state, must import proper password with finger touch keyboard (1), governor circuit (2) drives electromagnetism ratchet (5) and breaks away from groove, clockwise rotates handle and just can open door lock.Point keyboard of every touch, have the buzzing prompting, light interior light emitting diodes illumination 10 seconds simultaneously automatically, extinguish automatically after 10 seconds.Three input error passwords can be reported to the police 3 minutes.When in door, opening, can be manually opened as long as click the key that opens the door (K1).When cell degradation and during undertension, indicator lamp LED1 is long bright when not putting out, and at this moment must change ickel-cadmium cell.If electronic control system (1,2,4) is partly or entirely malfunctioning; in the time of can't opening with password; on the external door panel outdoors that can locate in emergency machine tapered end (11); the hole of brill 8; rotate counterclockwise tapered end (11) with key; stir electromagnetism ratchet (5); emission levels dead bolt (6); clockwise rotate handle; just lock can be opened; at this moment this lock is equivalent to Three-bearing machinery built-in lock, and when holing on external door panel, must bore the saturating topping of anti-the brill at this moment do not have malfunctioningly then can go out chimes of doom as warning system (3).
