Background technology
In recent years, financial sector recurred important cases.Data shows, national treasury larceny case more than 90% is interior theft case part, defalcate, collude from both within and without and coerced and open Ku Men by ruffian's violence, that is the crime of opening the door of use key and password.
At present worldwide, what on cashbox door, generally use is coded lock and the double key dedicated lock of frame for movement, is mainly the consideration aspect reliability; And the IC-card, the biological gate inhibition's intelligent product degree that occurred are in recent years high, but due to Shortcomings in reliability, on the cashbox door high to reliability requirement, be also not suitable for application, be mainly used on the isolating door of national treasury.And the potential safety hazard of national treasury just because of day hold-open door key and password illegally utilized, cause cashbox door to be opened warehouse-in crime by offender, the special control system that can preventing exactly of needing most like this illegally opened the door, also will meet requirement intelligent and that reliability has concurrently simultaneously technically.
Summary of the invention
The object of this invention is to provide the control device on a kind of cashbox door, is mainly to prevent illegal warehouse-in, stops case and occurs; In case of emergency, enable emergency set and can remove reliably native system, can not affect and go out normally warehouse-in work, make the anti-and technical precaution of people's air defense, thing form effectively restriction mutually with technological means like this.The invention the reliability of mechanical mechanism and programme controlled intellectuality are organically combined, is applicable to security needs and technical requirements on cashbox door completely.
The technical scheme adopting is: the control device on a kind of cashbox door, comprises cyclelog, actuating unit and emergency control apparatus.The mode of operation of cyclelog control actuating unit, this cyclelog is known technology, therefore repeated description not.
Technical essential of the present invention is: actuating unit comprises electromagnet, locator slide, base plate.Electromagnet is made up of magnet exciting coil, iron core and armature, is known technology.
Armature is made up of the first armature, the second armature and block, and the first armature, the second armature are fixedly connected with block, and the second armature is through the through hole on iron core, and the second armature upper end is positioned at dead bolt gap, and block is positioned at chute.Block can slide up and down in chute, and the shape of gap can stop that block passes through.
Straight down, emergency control apparatus is positioned at actuating unit top to the first armature direction of mounted actuating unit.Emergency control apparatus is formed by a mechanical code lock transformation, comprises lock body and dead bolt, and mechanical code lock is known technology, and improvement place is on dead bolt, to have offered chute and gap.
Electromagnet, locator slide are fixed on base plate, the lower end of the first armature is through the skidway hole on locator slide, and can in locator slide, slide, when the length of stretching out locator slide when the first armature reaches and sets numerical value, dead bolt gap blocks passing through of block, makes armature stop falling.
Actuating unit and emergency control apparatus are installed in position suitable in a chamber, when the first armature stretches out after locator slide, the first armature can control gate chamber in the motion of original transmission device, thereby control the unlatching of cashbox door.
Its operating principle is: controlled in the armature indentation locator slide of actuating unit by cyclelog by the program setting in advance or stretch out locator slide by gravity fall, also can make electromagnet energising attract armature or realize in armature indentation locator slide by the mechanical code lock of emergency set by Push switch simultaneously.
The pattern being set by cyclelog, energising makes iron core attract in armature indentation locator slide or stretch out locator slide by gravity fall.When falling under state under gravity, except controller control, there are two kinds of modes armature can be mentioned to indentation locator slide.
1) by designated person's Push switch, connect electromagnet power supply, armature is by adhesive, thereby makes in the first armature indentation locator slide, the at this moment state of this device in pre-unlatching, treasury management personnel can open cashbox door by mechanical key or password; In the time that switch disconnects, armature is subject to gravity automatically to fall to relevant position, and the first armature stretches out outside locator slide, and this device is in locking states.
2) by designated person's coded lock of operating machine, check the number to open and make in dead bolt retraction lock body, band moving armature moves to mechanical code lock direction, make in the first armature retraction locator slide, at this moment the state of this device in pre-unlatching, treasury management personnel can open cashbox door by mechanical key or password; In the time upsetting password, dead bolt stretches out lock body, and armature is by gravity fall, and the first armature stretches out outside locator slide, and this device is in locking states.
The present invention also can be applicable on other important warehouse door.
Its advantage is: overall structure of the present invention is simple and reliable, and long service life consumes energy low, and the present invention has extremely strong specific aim and practicality, is the dedicated control system for the customization of banking cashbox door.
The specific embodiment
A control device on cashbox door, comprises cyclelog 1, actuating unit and emergency control apparatus.Cyclelog 1 is controlled the mode of operation of actuating unit, and this cyclelog 1 is known technology, therefore repeated description not.
Actuating unit comprises electromagnet 6, locator slide 3, base plate 11.Electromagnet 6 is made up of magnet exciting coil, iron core 2 and armature 12, is known technology.Emergency control apparatus is positioned at actuating unit top.
Armature 12 is made up of the first armature 4, the second armature 9 and block 10, and the first armature 4, the second armature 9 are fixedly connected with block 10, and the second armature 9 is positioned at dead bolt gap 16 through through hole 15, the second armature 9 upper ends on iron core 2, and block 10 is positioned at chute 14.Block 10 can slide up and down in chute 14, and the shape of gap 16 can stop that block 10 passes through.
Emergency control apparatus is formed by 5 transformations of a mechanical code lock, comprises lock body 7 and dead bolt 8, and mechanical code lock 5 is known technology.Mechanical code lock 5 in emergency control apparatus obtains for commercially available coded lock improves, and improvement place is on dead bolt 8, to have offered chute 14 and gap 16.
Electromagnet 6, locator slide 3 are fixed on base plate 11, the lower end of the first armature 4 is through the skidway hole 13 on locator slide 3, and can be in the interior slip of locator slide 3, when the length of stretching out locator slide 3 when the first armature 4 reaches and sets numerical value, dead bolt gap 16 blocks passing through of block 10, makes armature 12 stop falling.
