Description

Electromagnetic coding electronic lock

The utility model belongs to lock, particularly a kind of electromagnetism digital code electronic lock.

Existing commercially available be rotating disc type number of degrees mechanical code locks, it all is mounted in the various safety cabinets, it mainly is made up of the garden iron pan that band in a number of degrees dish and three bursts, rotate the different direction of outer number of degrees dish and the different number of degrees, the breach that can make interior three garden iron is on a vertical line, this is that the breach of interior three garden iron pans can be used as a stroke distances, does not have any object of resistance shelves by breach, thereby reaches the purpose of unblanking.Not according to the direction of the unblanking order and the number of degrees accurately, the breach of so interior three garden iron pans just can not be on bar one vertical line as outer number of degrees dish, and that is can hinder any object of shelves to pass through breach, thereby reaches the purpose of closing.This lock number of combinations is few, and confidentiality is poor, uses extremely inconvenience, and safety factor is low.

The strong security that provides a kind of contact figure key and Electromagnetic Control to unblank, the electromagnetism digital code electronic lock that safety factor is high are provided the purpose of this utility model.

Technical solution scheme of the present utility model is such: decoding, storage sign indicating number, coding adopt one or more groups coaxial push button contact figure key, constitute unlocking mechanism by coil, bicycle freewheel and switch, constitute digital stepping circuit by resistance, electric capacity, controllable silicon or triode, magnetic relay, reset switch, drop hammer type vibration proof swtich warning circuit.

The utility model has the advantages that coefficient height easy to use, simple in structure, safe and reliable, secret, power saving, durable, be adapted to safety cabinet, national treasury, all kinds of door locks etc.

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing is a structure electrical schematic diagram of the present utility model.

Decoding key A1, A2, A3, storage sign indicating number key B1, B2, B3, key letter C1, C2, C3, resistance R 1, R2 in the accompanying drawing, battery E, controllable silicon G, capacitor C, unlock switch K1, reset switch K2, magnetic coil L, flywheel F, magnetic relay Q, vibroswitch K3, constant open contact Q2 are the input of warning circuit.

In operating principle shown in the drawings: establish and be encoded to 6,7,8 numbers, store sign indicating number 5,6,7, when opening when lock, place the decoding key, when the decoded number 6,7,8 of input and coded number 6,7,8 are identical, Push switch K1 connects circuit, coil L has electric current to pass through, and makes iron core production magnetic field, the spring leaf among the adhesive flywheel F, thereby flywheel F rotates, and lock is opened.When decoded number and the coded number of input were inequality, behind the Push switch K1, D point positive potential through resistance R 1, triggered controllable silicon G conducting, magnetic coil Q conducting, and Q1 disconnects, the warning of Q2 adhesive connection warning circuit.Stop to report to the police and must rotate decoding key input 5,6,7 number identical with storing sign indicating number 5,6,7, Push switch K2 resets, and stops warning.The key of decoding then rotates the number 6,7,8 that re-enters 6,7,8 digital corresponding codings, and Push switch K1 connects unlocking mechanism, and lock is opened.

When the vibration lock body, after the 3 moments connection of drop hammer type K switch, trigger the controllable silicon conducting, relay Q has electric current to pass through, and Q2 connects warning circuit and reports to the police.Necessary decoding key input 5,6,7 numbers that rotate that stop to report to the police are identical with storage sign indicating number 5,6,7, and Push switch K3 resets and gets final product.

Embodiment: with reference to accompanying drawing, decoding key A1, A2, A3, storage sign indicating number B1, B2, B3, key letter C1, C2, C3 are the coaxial push button contact figure keys that adopts one or more groups.The key of decoding is installed in the lock body outside, so that operation, storage sign indicating number, key letter are mounted in the lock body, and it is many more to establish storage code character number, and its secret coefficient is high more.Unlocking mechanism is to use bicycle freewheel F, magnetic coil L is installed in the middle of flywheel, and be serially connected in the circuit, energising back iron-core coil produces magnetic field, the spring leaf adhesive in the flywheel, thereby flywheel rotating opening lock, by magnetic relay Q, controllable silicon G K switch 2 constitutes digital stepping circuit, coiling on iron core, the number of turn is decided according to the size of electric current, and relay Q and resistance R 2 controllable silicon G are serially connected in the circuit, and K switch 2 is attempted by between positive supply and relay and the controllable silicon, relay Q constant open contact Q2 circuit input end taking alarm, the element in the circuit is installed in the box body.
