Description
Technical field
The utility model relates to a kind of electromagnetic lock, and especially a kind of power consumption is little, long service life, passive electrical magnetic padlock that reliability is high.
Background technology
Electromagnetic lock is the indispensable equipment that prevents in the operation power that five kinds of operating accidents from taking place.Existing be installed on that high-voltage switch gear locking electromagnetic lock cashier's office in a shop need exchange or the accessory power supply of direct current, not only power consumption is big, and needs long-time energising to keep when opening the maintenance of cabinet door, makes coil heating easily and burns out the line bag.According to statistics, the fault rate of this kind electromagnetic lock is higher, in case break down, the cabinet door just is difficult to open, and opens the door by force and damages cabinet body structure easily, and often the recovery of incuring loss through delay after overhauling is sent.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, provides that a kind of power consumption is little, long service life, passive electrical magnetic padlock that reliability is high.
Technical solution of the present utility model is: a kind of passive electrical magnetic padlock, comprise lock body and electron key, it is characterized in that: be provided with the bistable state magnet that constitutes by yoke, coil and magnet in the housing of described lock body, coil joins by power supply wiring and signal jack, is connected to dead bolt and the toggle of locking a door with the bistable magnetic iron phase; Be provided with power supply E in the housing of described electron key, power supply E and regulator block W1 join, and the output end vo ut of regulator block W1 is by the V of resistance R 1 with Logic control module IC1
+End joins, the V-end ground connection of Logic control module IC1, pin P16 and the switch S 1 of Logic control module IC1 are joined, the pin P8 of Logic control module IC1 joins with high-voltage signal input GY by resistance R 2, the pin P13 of Logic control module IC1 joins by resistance R 3 and the base stage of triode Q1, the grounded emitter of triode Q1, the colelctor electrode of triode Q1 and relay K 1 are joined, and the electric contact K1-1 of relay K 1 is connected to output end vo ut and the conduction of regulator block W1 and inserts between the axle CZ.
The utility model need not to provide accessory power supply, directly unblanked by charged key electrical verification, solve five anti-difficult problems of passive locking fully, electrification in high voltage forced blocking, electrical verification release are once finished, control very simple and reliablely, can save power supply and prolong application life of product.
Description of drawings
Fig. 1 is the utility model embodiment lock body structure schematic diagram.
Fig. 2 is the circuit theory diagrams of the utility model embodiment electron key.
The specific embodiment
The specific embodiment below in conjunction with description of drawings the utility model embodiment.Lock body is as shown in Figure 1, 2: be provided with the bistable state magnet 1 that is made of yoke, coil and magnet in the housing of lock body, coil joins by power supply wiring and signal jack 2,3, is connected to dead bolt 4 and the toggle 5 of locking a door with bistable state magnet 1; Be provided with power supply E(12V in the housing of described electron key), the input Vin of power supply E and regulator block W1 joins, and the output end vo ut of regulator block W1 is by the V of resistance R 1 with Logic control module IC1
+End joins, the V-end ground connection of Logic control module IC1, the pin P16 of Logic control module IC1 and switch S 1(press button) join, the pin P8 of Logic control module IC1 joins with high-voltage signal input GY by resistance R 2, the pin P13 of Logic control module IC1 joins by resistance R 3 and the base stage of triode Q1, the grounded emitter of triode Q1, the colelctor electrode of triode Q1 and relay K 1 are joined, and the electric contact K1-1 of relay K 1 is connected to output end vo ut and the conduction of regulator block W1 and inserts between the axle CZ.
Locking relies on the magnetic force of lock a door toggle 7 and magnet 3 to realize.When unblanking, Push switch S1, Logic control module IC1 electrical verification operation, if high-voltage signal input GY has high-voltage signal, then Logic control module IC1 pin P13 does not have signal output, and relay K 1 is failure to actuate, electric contact K1-1 still is in normally open, the slotting axle of a conduction CZ does not have voltage output, and this moment, power supply wiring 4 also must not be electric with signal jack 5 or signal jack 6, and the magnetic force of magnet still keeps locking.If high-voltage signal input GY does not have high-voltage signal, then Logic control module IC1 pin P13 has signal output, relay K 1 action, electric contact K1-1 closure, conduction is inserted an axle CZ voltage output, this moment power supply wiring 4 with signal jack 5 or signal jack 6 also electric, coil 2 gets thereupon, produce the magnetic force opposite, finish and unblank with magnet.
