Description

Bank vault door security control device

Technical field

The utility model relates to a kind of door lock, particularly relates to a kind of vault door security control device that is used to be equipped with some sliding extension control pins.

Background technology

At present, financial department cash exchequer door all is the standard door that some sliding extension control pins are housed.Because the national treasury door is very firm, the external staff commits a crime and is difficult to succeed.According to the interrelated data introduction, the national treasury theft case overwhelming majority is internal staff or collusion from both within and without crime, or pipe storehouse personnel coerce by ruffian's violence and open Ku Men, that is uses key and password to open the door, and its crime time all is at non operation time.So the control non operation time opens the door and is very important.

It is reported, pseudo-Manchukuo period, the Japanese once in Changchun one bank's warehouse door mechanical time lock (now scrapping) was installed.A new generation's mechanical time lock needs pipe storehouse personnel to operate every day, and usually inoperation of some godown keepers is perhaps forgotten operation, thereby performed practically no function, and has lost the strick precaution meaning; Several years ago, Shanghai, Beijing once had American-European electronic time to lock the city, because technical reason, its performance incompatibility Chinese market does not form and sells; Along with electronics is taken the photograph (record) development as technology, TV monitoring system is extensive use, but this system can only monitor and can not control, thereby is difficult to stop internal staff or collusion from both within and without crime; The Fingerprint Lock that the applying biological recognition technology is made, palmmprint lock etc. can not directly be installed on the national treasury door because of there is the problem of " false rejection " and " misconnection receipts " in it.Therefore, still there is potential safety hazard in bank's storehouse.

Summary of the invention

The purpose of this utility model is exactly to be coerced by violence and steal the generation of robbing the national treasury case in order to prevent to defalcate, collude from both within and without, manage the storehouse personnel, provides that a kind of simple installation, working stability are reliable, the safety control at bank exchequer door of fully automatic operation.

The technical scheme that adopts is:

Bank vault door security control device comprises control circuit for electromagnet, open and close lock executing agency and emergency opening mechanism.

Control circuit is made up of isolating transformer GB, two-way electronic time switch HSK, uses the 220V AC power.Lead-out terminal C, the D of two-way electronic time switch HSK meet electromagnet DC respectively ₁, DC ₂Coil, by the loop that is electrically connected to form, for electromagnet provides power supply.

Open and close lock executing agency comprises electromagnet 1, electromagnet 6, base plate, lock nose, dead bolt, dead bolt driving lever.The iron core of the iron core of electromagnet 1 and electromagnet 6 is oppositely arranged.The iron core of electromagnet 1 is fixedlyed connected with the upper end of dead bolt driving lever, fixedlys connected with the dead bolt rear end in the lower end of dead bolt driving lever.Electromagnet 1, electromagnet 6, dead bolt driving lever and dead bolt are installed in the lock housing body.Lock housing body and lock nose correspondence are installed in desired location in national treasury every body.The dead bolt through hole that the dead bolt front portion is passed on the lock housing inserts in the lock nose.

The emergency opening device comprises finger, shift fork, handwheel and coded lock.Fixedly connected with dead bolt in the finger upper end, insert in the shift fork slot of shift fork upper end its lower end.Shift fork middle part is provided with handwheel, and hand wheel shaft passes the axis hole on the shift fork, and with the axis hole interference fit.Coded lock is arranged on shift fork lower end one side, and the tone mark dish of coded lock is positioned at national treasury door external body.When the gap on three control discs of coded lock overlaps, move behind the shift fork and can insert in the gap.Handwheel and coded lock tone mark dish are arranged on national treasury every external body.

At the shift fork back side and handwheel corresponding position limited force mechanisms is set.The limit force mechanisms comprises limit power ring, limit power ball, force-limit spring and limit power bolt.Limit power ring is coaxial with handwheel.On limit power ring, offer bolt hole, have the V-type groove on the limit power dish axle.Limit power ball reinstalls force-limit spring after packing in the bolt hole, screws in bolt at last, and the part of limit power ball is entered in the V-type groove on the limit power annulate shaft.

The operating principle of bank vault door security control device:

Every day, business ended when coming off duty, two-way electronic time switch A road energising (one second), electromagnet 6 adhesives, its iron core iron core of tractive magnet 1 simultaneously moves in the same way, thereby drive finger, dead bolt and move (as moving right) in the same way, dead bolt stretches out the lock nose, blocks the baffle plate that is installed on the national treasury door extension and contraction control pin linkage part, realizes the locking purpose.Before next day business is opened the door, (one second) is connected on the B road of two-way clock switch, make electromagnet 1 adhesive, the iron core of electromagnet 1 moves (as being moved to the left) after driving finger and dead bolt, dead bolt withdrawal lock nose, national treasury door extension and contraction control pin can freely move, and pipe storehouse personnel can use mechanical lock key and coded lock password normal door.

Need open Ku Men at the non operation time of setting in order to solve special circumstances such as meeting earthquake, floods, fire, can make pipe storehouse personnel be subjected to the problem of effective restraint again, designed the emergency opening device especially, its password is by Subscriber Unit person in charge or security department's keeping.

When emergency case occurring and need open the national treasury door, can stir coded lock tone mark dish by password, make the gap of three control discs overlapping, when all aiming at the retaining pin of shift fork, rotation hand wheel, the shift fork lower end is moved to right, and shift fork lower end retaining pin enters in three gap on the control disc, and shift fork top is moved to the left simultaneously, shift fork upper port right side wall is replaced on finger, and promote finger and move to left, finger drive that dead bolt moves to left and indentation lock nose in, the available mechanical lock key of national treasury door is opened, after the use, turnstile makes shift fork retaining pin break away from the control disc, then clockwise or the above tone mark dish that rotates three circles between the inverse time, dials disorderly control disc.Coded lock is commercially available known product.

When in case illegal person's attempt is opened the national treasury door by rotation hand wheel, owing to do not know unlocking cipher, therefore can't make three gap on the control disc overlapping, therefore shift fork retaining pin can not enter the gap on the control disc, shift fork can not rotate, therefore shift fork can not be stirred finger, and the national treasury door lock can't be opened.

If the lawless person wants by powerful rotation hand wheel, make the distortion of shift fork retaining pin, and then when stirring finger and open the national treasury door lock with shift fork, limit power ball in the limit power ring outwards moves along limit power ring radial hole, make between limit power ring and the hand wheel shaft and slide, make handwheel idle running, can guarantee that like this shift fork pin is indeformable, the national treasury door lock can not be opened.

Vault door security control device, can effectively control internal staff crime and lawless person colludes from both within and without and commits a crime at non operation time, particularly manage under the situation that the storehouse personnel are coerced by ruffian's violence, can guarantee that national treasury safety is convenient to manage the storehouse personnel again and contends with criminals.From anticrime angle, can give up offender's crime thought and avoid the generation of case.The utility model can be widely used on the national treasury door of units such as bank, postal service.
