Description
Technical field
The utility model relates to a kind of lock, relates in particular to a kind of no afterburning multiconductor formula lock.
Background technology
Be flooded with various different lockset in the life, various cylinder locks commonly used, remote control lock and Fingerprint Lock are arranged, but the marble amount of cylinder lock is more and more, it is more and more numerous and diverse to unblank, and buys new lock " training " earlier, and key comes greatly more, more and more heavier, carry extremely inconvenient.It is extremely unhygienic that mutual friction that simultaneously key is many produces dirt.Required power is increasing when unblanking, and old children can open easily.It is just big that key carries on one's body slightly a motion noise, opens behind the cylinder lock senile abrasion to be not easy.The defective of remote control lock and Fingerprint Lock is the cost height, that non-general family can afford to use, simultaneously unblank also numerous and diverse.
Summary of the invention
The purpose of this utility model is to provide a kind of no afterburning multiconductor formula lock, has solved present cylinder lock and has carried inconvenience, needs the afterburning problem that turns to open, and has avoided the expensive problem of remote control lock and Fingerprint Lock simultaneously.
The utility model is achieved like this, it comprises key plug, key socket, power supply, lock body, contact chip, coil, permanent magnet, dead bolt, draw-in groove, lock, permanent magnet ⅰ, contact switch, power failure emergency power supply access point, the key plug key socket that is connected, power supply, key socket and lock body are connected in series successively, it is characterized in that key plug is the plastics wiring board, its tow sides are respectively equipped with several contact chips, the contact chip corresponding matching of the contact chip of key plug and key socket, contact chip connects power supply respectively by lead and lock body forms path, side in the lock body is provided with two coils at a distance of certain distance, be placed with permanent magnet between two coils, the fixedly connected dead bolt in the bottom of permanent magnet, the rear end of dead bolt has draw-in groove, draw-in groove and lock are connected, the top of lock connects permanent magnet ⅰ, permanent magnet ⅰ is near coil, the sidewall bottom of key socket, the fixedly dead bolt of the dead bolt of lock body and lock body is connected with contact switch respectively, and the upper end of contact chip is provided with two power failure emergency power supply access points.
Described power supply connects warning device.
Technique effect of the present utility model is: this lock need not reinforcing, and is all-ages, lock vi have high safety and process simply, and cost is low, and key is that plastics add the circuit version, and light health is easy to carry.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is achieved like this.Key plug 1 key socket 2 that is connected, power supply 3, key socket 2(key socket 2 have two, one is used for unblanking outdoors, one is used for the room drawback lock and is connected in parallel) and lock body 4 be connected in series successively, key plug 1 is the plastics wiring board, its tow sides are respectively equipped with several contact chips 5, and there are two power failure emergency power supply access points 14 the key top.The contact chip corresponding matching of the contact chip of key plug 1 and key socket 2, contact chip 5 connects power supply 3 respectively by lead and lock body 4 forms path.Side in the lock body 4 is provided with at a distance of between 6, two coils 6 of two coils of certain distance and is placed with permanent magnet 7, the fixedly connected dead bolt 8 in the bottom of permanent magnet 7, and the rear end of dead bolt 8 has draw-in groove 9, and draw-in groove 9 is connected with lock 10.The top of lock 10 connects permanent magnet ⅰ 11, and permanent magnet ⅰ 11 is near coil 6, and the fixedly dead bolt of the sidewall bottom of key socket 2, the dead bolt of lock body 4 and lock body 4 is connected with contact switch 12 respectively, and power supply 3 connects warning device 13 simultaneously.Operating principle: utilize the magnet same sex to repel each other, the characteristic that there is a natural attraction between the sexes.A middle permanent magnet is fixed on the saddle of dead bolt 8, and each fixes a coil 6 both sides (identical with the length of permanent magnet) separated by a distance.As long as key plug 1 is inserted key socket 2, the contact switch 12 on the key socket 2 is in off-state, at this moment at coil switch power when opening the door.Make the right of the coil in left side become the N utmost point just to repel each other, make the left side of the coil on right side become the N utmost point just to inhale mutually with the permanent magnet S utmost point with the permanent magnet N utmost point.Unidirectional like this one scolds a suction, produces powerful thrust to the right and finishes unlocking action.Simultaneously the permanent magnet ⅰ 11 of lock 10 has also just also produced thrust to the right with the right magnetic homopolarity of the coil on right side, has spurred the lock 10 that is stuck on the deck.At this moment door is opened, the fixedly dead bolt upper contact switch of lock body 4 is off-state (thereby not locking a door automatically after guaranteeing to extract key), and the contact switch in the dead bolt of lock body 4 is on-state, extracts key and just finish lock a door (not needing key) by the not same-action of three contact switch automatically in the time will locking a door.Concrete steps are: the contact switch of extracting after opening the door on the key socket 2 is in connection status, and fixedly the contact switch in the dead bolt (having oppressed contact switch behind the door owing to close) also is in connection status.The circuit of locking a door is like this switched on automatically.Both to coil electricity, the both positive and negative polarity wiring of power-on circuit was just opposite with the both positive and negative polarity wiring of the circuit that opens the door.What both produced on the coil the right in left side is that the S utmost point is inhaled with the permanent magnetism iron phase, repels each other at the coil left side on the right side generation S utmost point and permanent magnet 7, and the powerful thrust that produces is left finished the action of locking a door.Simultaneously the right of right side coil produces is that the N utmost point is just inhaled generation thrust left mutually with the S utmost point of permanent magnet ⅰ on the lock again lock is stuck in the draw-in groove, contact switch on the locked back compressing of the dead bolt dead bolt makes it be the power supply that off-state has been cut off the circuit of locking a door, and finishes the task in the source that cuts off the power supply again.
This lock uses 220 volts of civil powers, supplies with the power supply of coil 12V by becoming direct current after transformation, the rectification.One switch is being installed outdoors, is being closed and to cut off the electricity supply with power saving behind the door.
Install when the mainly anti-lawless person of warning device goes to attempt to unblank and use.Principle: when not being this lock key when opening the door, cause short circuit, voltage and current all can raise and cause alarm equipment alarm like this.
