Description

Bank exchequer door automatic control device

Technical field

The utility model relates to a kind of door lock, particularly relates to a kind of exchequer door automatic 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, provide that a kind of simple installation, working stability are reliable, fully automatic operation at bank exchequer door automatic control device.

The technical scheme that adopts is:

Bank exchequer door automatic control device comprises control circuit for electromagnet and open and close lock executing agency.

Control circuit is made up of isolating transformer GB, electronic time switch HSK, uses the 220V AC power.Electronic time switch HSK terminal C, D connect the two ends of electromagnet coil respectively, by the loop that is electrically connected to form, for electromagnet provides power supply, are known technology.

Open and close lock executing agency comprises lock housing body, electromagnet, lock nose and dead bolt assembly.Lock housing body and lock nose correspondence are installed in desired location in national treasury every body.Electromagnet is fixed in the lock housing body, and the iron core vertical fixing of electromagnet has the dead bolt driving lever.The dead bolt assembly comprises dead bolt, back-moving spring and latch assembly.The dead bolt front end is fixed with spring stop piece, and the dead bolt sidewall is provided with stairstepping closed type slideway.Stairstepping closed type slideway is connected and composed by sliding way and glide path.Be provided with block in the middle of sliding way and glide path, the block front end has the V-type groove.The glide path front portion has step 1, step 2 and step 3 successively.Step 1 is higher than step 2, and step 2 is higher than step 3.Sliding way and slip place, following road, the left end of sliding way is lower than the step 3 of glide path, and the right-hand member of sliding way is higher than glide path (seeing accompanying drawing 3), and forms step 4 with glide path.Latch assembly comprises housing, slide block, chucking contact and support spring.Dead bolt assembly housing front end face is provided with the slide block passage, and the dead bolt through hole is arranged at dead bolt assembly housing bottom.The slide block below is provided with take-up housing, and slide block and take-up housing are an overall structure.Chucking contact top is provided with spring base, and chucking contact and spring base are an overall structure.Take-up housing is contained in the housing, slide block inserts in the slide block passage, support spring and spring base are packed in the take-up housing successively, the support spring upper end is replaced on take-up housing, the lower end is replaced on the spring base of chucking contact, in the stairstepping closed type slideway on the chucking contact insertion dead bolt, the chucking contact can move along slideway.The housing of dead bolt assembly is fixed on the lock housing body, and dead bolt passes the dead bolt through hole on this housing, and inserts in the lock nose, and back-moving spring is sleeved on the dead bolt, and the back-moving spring front end is replaced on the spring stop piece on the dead bolt, and its other end is replaced on the housing of latch assembly.

The operating principle of bank exchequer door automatic control device:

When needing locking, electronic time switch energising (as one second), electromagnetic actuation, when adhesive, electromagnet core moves drive dead bolt driving lever and moves in the same way, and move behind the promotion dead bolt, the chucking contact can only enter glide path (because of the sliding way of sliding way and glide path joint is higher than glide path because of step 4 stops, the chucking contact can not enter sliding way), when the chucking contact is positioned at the preceding stop A place of glide path (seeing accompanying drawing 4), at this moment dead bolt stretches out the lock nose, blocks the baffle plate that is installed on the national treasury door extension and contraction control pin gearing attachment, realizes the locking purpose.

In above-mentioned electromagnet outage moment, because the elastic force of back-moving spring makes the dead bolt reach, can not advance glide path because the chucking contact is blocked by step 1, and can only enter along the slope of step 1 in the V-type groove of block, the V-type groove overcomes elastic force, makes dead bolt static.Because the reach of above-mentioned dead bolt promotes the reach of dead bolt driving lever, and the drive electromagnet is advanced to desired location.When next day, business was opened the door, clock switch was connected, and makes electromagnet adhesive once more, makes the dead bolt driving lever promote once more to move behind the dead bolt again.At this moment, the chucking contact can only enter sliding way from step 3 owing to stopped by step 2, cut off the power supply owing to magnet afterwards, back-moving spring makes the dead bolt reach, and makes the chucking contact enter the interior back stop B of glide path, in the dead bolt indentation lock nose, national treasury door extension and contraction control pin can freely move.

Bank exchequer door automatic 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.
