Abstract
The utility model provides a computer cipher lock, which relates to a lock controlled by the electric power, and especially belongs to the field of a computer cipher control device. The utility model is mainly composed of a digital keyboard, a computer control board, a terminal control circuit, a micro-motor, a lockset execution mechanism, an automatic alarm device, an under-voltage indication circuit, a lock casing, etc. Especially, the computer cipher lock is easy to open when the work voltage is low, has good self-locking performance, and is not easy to prize. In addition, the utility model has the advantages of simple circuit, complete function and low manufacture cost.
Description
The utility model relates to a kind of lock of electric power control, particularly belongs to a kind of computer cipher control device field.
Disclosed Computerized puzzle lock of Chinese patent ZL90206421.5 and Chinese patent 91109297.8 disclosed microcomputerized puzzle locks.The known Computerized puzzle lock of this class generally includes: digital code keyboard, electronic circuit control board, code device, nixie display, micro machine, unblank to carry out controlling organization or the like, basic principle is if the password that deposits in the number of digital code keyboard input and the lock matches, the circuit of control micro machine is connected, by the unlatching of motor rotation control locking execution mechanism.Control circuit can be realized the processing of reporting to the police, forgetting Password, the processing of outage or the like function.Locking execution mechanism roughly has two kinds, and a kind of is by the motor linkage eccentric mechanism, and another kind is gear, tooth bar interoperation, and these two kinds of kinds of drive have following shortcoming: (1) is difficult for opening when operating voltage is low; (2) easily pry open owing to its reasons in structure.
The utility model purpose is the deficiency according to the above, provides a kind of pick-proof performance Computerized puzzle lock more superior and that open easily under the lower situation of voltage.
The utility model is mainly by numeric keypad, computer program controlled plate, the terminal control circuit, micro machine, locking execution mechanism, autoalarm and under-voltage indicating circuit, formations such as lock housing, numeric keypad and computer program controlled plate are combined into one, and link with the terminal control circuit, micro machine and locking execution mechanism link, inventive point is a locking execution mechanism by the screw rod (9) that links with the micro machine variable-speed shaft, locking bolt (10), lock body overcoat (3) constitutes, locking bolt (10) and screw rod (9) threaded engagement, locking bolt and lock body overcoat matched in clearance, have on the locking bolt stopper slot (1) with stopper slot (1), be fixed with jackscrew (2) on the corresponding lock housing in position.
The inventor is through comparing test to various locking execution mechanism for many years, and the advantage of invention the utility model structure is: (1) is because the speed of screw thread transmission is more casual, so still action easily when voltage lower (particularly battery uses the long period); (2) self-locking property is good, and then the pick-proof effect is good especially.
Accompanying drawing 1 is the utility model principle schematic;
Accompanying drawing 2 is the utility model locking execution mechanism structure chart;
Accompanying drawing 3 is the utility model circuit diagram;
The utility model feature and other feature are described in further detail by embodiment below in conjunction with accompanying drawing:
Show that as accompanying drawing 1,2 computer tablet adopts special IC TWH9103, with the storage memory of computer cipher, check functions such as unlatching, error code time-delay, warning, state control and control by preset program.Computer tablet is a known technology, and its performance is not described further.DC micromotor (5) is fixed on the support (6) by bolt (4), screw rod (9) links by universal knot (8) and micro machine variable-speed shaft (7), locking bolt (10) is contained in the lock body overcoat (3), the two matched in clearance, screw rod (9) and locking bolt (10) threaded engagement have stopper slot (1) stopper slot interpolation that spacing jackscrew (2) is arranged on locking bolt, when micro machine obtains to drive signal, drive screw rod (9) action, and then make locking bolt (10) action.
The utility model uses:
1, store the password and the program of unblanking:
Show when connecting K as accompanying drawing 3
2, IC
1, IC
2Start working.Connect the storage K switch this moment
1, just can input password by keyboard, after connect and store key " * ", with K
1Reset, password setting finishes.During locking, press HK
1, locking bolt is released in the motor counter-rotating.When unblanking, input password and enter key " # ", IC
1, 17 pin export one pulse voltage → IC
2, 2 pin trigger → 3 pin output high level → BG
2, BG
3Clad pipe conducting → relay L
1The contact transposition, the positive twist lock bolt of motor resets, at this moment IC
2Time-delay finishes, and 3 pin are low level, and motor is stopped power supply, and whole unblanking needs 8 seconds.
2, report to the police automatically:
During locking, if during secondary input error code, Y
1Send 0.5 second warning, continue for the third time to input by mistake, computer sends signal, triggers BG
4, BG
5Compound conducting, → relay L
2Adhesive contact transposition → warning circuit KD9561, TWH68 get electric → Y
2Send chimes of doom.
3, under-voltage indicating circuit is by BG
6, BG
7, composition such as TR.When supply voltage is higher than 4V, BG
6Be conducting state, BG
7Base potential is clamped at below the 05V.And when supply voltage is lower than 4V, BG
6Base voltage ends less than 0.5V, this moment BG
7Base potential rises to greater than 0.7V, utmost point conducting, and the TR luminous tube shows that reminding needs to change battery.
" VX " be under the particular case without cipher unlocking device, the user can oneself install an appropriate location.
" TV " is an external source of stable pressure socket, in particular cases power supply.
Because the utility model power consumption is less, use 4 joint 1# batteries usually, can normally use more than 70 days.
It is terse to the utlity model has the design of integer electro-circuit structure, and controlling unit is few, safety system Number is big, and is with low cost, and particularly the locking execution mechanism design is unique, and the locking bolt self-locking performance is strong, The pick-proof performance is good.
