Abstract
The utility model relates to a reliable safe. The technical scheme is that the reliable safe comprises a safe body, a left safe door, a right safe door, a top-down lock and a safe door monitor. The top-down lock is mounted in the right safe door. The safe door monitor comprises a stroke switch and a monitoring circuit, wherein the stroke switch is mounted in the left safe door and corresponds to transverse lock rods of the top-down lock, and a normally open contact of the stroke switch is connected with a monitoring circuit. The safe door monitor monitors the lock rods of the top-down lock, when the lock rods move to the locking positions and trigger the stroke switch, corresponding prompt signals can be sent, thus, fake locking is effectively avoided, and safety of confidential files is improved.
Description
Technical field
The utility model relates to a kind of safe cabinet that can effectively prevent the false lock of cabinet door, belongs to office furniture technical field.
Background technology
Safe cabinet is the office facility for depositing classified document, and its door lock should have than the higher reliability of other cabinet lock.Safe cabinet generally has two doors in left and right, and the two is locked by same set of Tiandi lock.Accompanying drawing 1 is the structure (lock-out state) of Tiandi lock lock core, its operating principle is: lock core rotating disk 4 was both coaxially connected with the knob that opens the door, again by the locking bar up and down of push rod shifting block control Tiandi lock and stretching of horizontal locking bar, need to open cabinet door time, separate lock slide 1 moves right under the driving of the motor of unblanking, dead bolt 2 is pressed into rotating disk 4, then turn clockwise rotating disk 4(now dead bolt 2 under spring action, withstand on block 3 and along block 3 and slide), make upper and lower locking bar and laterally locking bar retraction, cabinet door can be opened; After approximately 5 seconds, solution lock slide 1 is moved to the left and leaves rotating disk 4, ready for lock a door next time; After cabinet door is closed, rotate counterclockwise rotating disk 4, after locking bar puts in place, dead bolt just leaves block 3 and from the interior ejection of rotating disk 4, stops rotating disk 4 to turn clockwise, thereby by locked rotating disk 4.
For preventing the false lock of cabinet door, some safe cabinet is provided with cabinet door monitoring device, and this device all sends cue to operator at every turn after locking a door, and operator can relievedly be left.But the cabinet door monitoring device of existing safe cabinet is all generally take cabinet door as monitoring target, as long as closing to put in place, cabinet door just thinks that door locks, if operator is closed and rotating disk 4 is not rotated counterclockwise and put in place behind the door, dead bolt not yet leaves block 3 and ejects, just there will be false lock phenomenon, although now cabinet door monitoring device is given the signal of going out and having locked, the rotating disk 4 that turns clockwise still can be by door-lock opening, so just reduce the reliability of safe cabinet, cannot guarantee the safety of classified document.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of safe cabinet of high reliability is provided, and improves the safety of classified document.
Problem described in the utility model realizes with following technical proposals:
A kind of safe cabinet of high reliability, formation comprises cabinet, left cabinet door, right cabinet door, Tiandi lock and cabinet door monitoring device, described Tiandi lock is arranged in right cabinet door, described cabinet door monitoring device comprises travel switch and observation circuit, it is interior and corresponding with the horizontal locking bar of Tiandi lock that described travel switch is arranged on left cabinet door, and its constant open contact connects observation circuit.
The safe cabinet of above-mentioned high reliability, described observation circuit comprises single-chip microcomputer, locking bar put in place indicator lamp and triode, the grounded emitter of described triode, colelctor electrode connects positive source through the locking bar indicator lamp that puts in place, its base stage connects the P2.0 port of single-chip microcomputer through coupling resistance, the P2.1 port of single-chip microcomputer is through the constant open contact ground connection of travel switch and connect positive source through pull-up resistor.
The safe cabinet of above-mentioned high reliability, described locking bar put in place indicator lamp adopt light emitting diode.
The safe cabinet of above-mentioned high reliability, the described locking bar indicator lamp that puts in place also can be substituted by buzzer.
Cabinet door monitoring device of the present utility model is take the locking bar of Tiandi lock as monitoring target, only have and in the time that locking bar moves to latched position and triggers travel switch, just can send corresponding cue, so just effectively avoid the generation of false lock phenomenon, thus the safety that has improved classified document.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of safe cabinet lock core;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the electrical schematic diagram of cabinet door monitoring device.
In figure, each list of reference numerals is: 1, separate lock slide, 2, dead bolt, 3, block, 4, lock core rotating disk, 5, cabinet, 6, left cabinet door, 7, upper locking bar, 8, right cabinet door, 9, Tiandi lock, 10, lower locking bar, 11, horizontal locking bar, U1, single-chip microcomputer, K, travel switch, D, the locking bar indicator lamp that puts in place, T, triode, R1, pull-up resistor, R2, coupling resistance.
The specific embodiment
Referring to Fig. 2 and Fig. 3, the utility model comprises cabinet 5, left cabinet door 6, right cabinet door 8, Tiandi lock 9 and cabinet door monitoring device, and wherein cabinet door monitoring device comprises single-chip microcomputer U1, travel switch K, locking bar put in place indicator lamp D, triode T, pull-up resistor R1 and coupling resistance R2.
Tiandi lock 9 is arranged in right cabinet door 8, and when locking cabinet door, the upper locking bar 7 of Tiandi lock 9 and lower locking bar 10 insert in cabinet 5, and laterally locking bar 11 inserts in left cabinet door 6.If horizontal locking bar 11 stretches out completely while locking a door, its left end will withstand on the trigger head of travel switch K, make the constant open contact closure of travel switch K, single-chip microcomputer U1 sends driving signal by P2.0 port after the closure signal of travel switch K being detected, make locking bar put in place indicator lamp D(or buzzer) electric, prompting operation person's door locks.If horizontal locking bar 11 does not stretch out completely while locking a door, cabinet door monitoring device just can not send cue, impels operator to continue to rotate counterclockwise rotating disk 4, until receive cue.
Travel switch K in Fig. 2 is arranged in left cabinet door 6, also can be arranged in cabinet 5, and make its trigger head corresponding with upper locking bar 7 or lower locking bar 10 while specifically enforcement.
Locking bar in Fig. 3 puts indicator lamp D in place can be alternative with buzzer, certainly can also substitute with audible-visual annunciator.For cost-saving, single-chip microcomputer U1 can adopt the single-chip microcomputer of safe cabinet controller.
