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, 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 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 1, 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 shell body, the tight assembly of ratchet kayser, upper contact head, following contact, back-moving spring and dead bolt.

Upper contact head is made up of baffle plate and hollow push rod, fixedlys connected with baffle plate in the hollow push rod upper end.Be evenly equipped with 6 Λ type grooves on the hollow push rod lower surface, the positioning key of vertical setting is arranged between adjacent two Λ type grooves, positioning key and hollow push rod are structure as a whole.

Following contact is made up of thimble and hollow shift fork seat, fixedlys connected with hollow shift fork seat in the thimble lower end.Be evenly equipped with three shift forks on hollow shift fork seat, three shift forks upper end has identical domatic.The dead bolt front end inserts in the dead bolt jack on the hollow shift fork base rear end face.

The tight assembly of ratchet kayser comprises a cylinder, and 6 ratchets are arranged on the cylinder lower surface, equidistantly on the cylinder inner wall is provided with 6 slideways.Cylinder is fixed on the inwall of shell body.

Back-moving spring is installed in the bottom of shell body, and is sleeved on the dead bolt, and the back-moving spring front end is replaced on the spring stop piece that is fixed on the dead bolt, and the back-moving spring rear end is replaced on shell body.The thimble of following contact inserts in the hollow push rod of upper contact head, and three shift forks of following contact enter respectively in the Λ type groove corresponding on the hollow push rod lower surface of upper contact head.Then upper and lower contact and dead bolt are packed in the shell body.6 positioning keys on the upper contact head enter respectively in the corresponding slideway on the ratchet kayser, make the upper contact head can only upper and lower motion and can not rotate.Dead bolt passes the dead bolt through hole on the shell body, inserts in the lock nose.Shell body is fixedlyed connected with the lock housing body by two poles.Shell body is parallel with iron core.

The operating principle of bank exchequer door automatic control device:

When needing locking, electronic time switch energising (as a second), electromagnet 1 adhesive, when adhesive, electromagnet core moves drive dead bolt driving lever and moves in the same way.Move behind the baffle plate of promotion upper contact head, and move after driving hollow push rod, hollow push rod promotes to move behind the contact down, and three shift forks on the following contact are replaced respectively on three ratchets of the tight assembly of ratchet kayser, and will descend contact to pin can not move forward.Promote when moving behind the following contact to move behind the dead bolt, 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.Switch on one second when outage, the upper contact head desired location that rebounds again, from and promote the desired location that iron core is moved back into iron core.When next day, business was opened the door, clock switch is connected (one second), make electromagnet 1 adhesive once more, make the dead bolt driving lever promote the baffle plate of upper contact head once more again, and move after driving hollow push rod, promote to move behind the contact down, make and move behind three shift forks that blocked by above-mentioned ratchet and rotate the disengaging ratchet, during outage, the following contact spring that is reset promotes to move forward, and drives in the dead bolt indentation lock nose.Following contact moves forward and promotes the upper contact head reach, and drives the iron core reach, and 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.

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.
