Abstract

The utility model discloses an electronic alarm lock which mainly comprises a lock body 6, a lock core 10, a bolt 9, a bolt driving rod 16, a sink-head 8, a sink-head driving plate 7 and a bolt security forelock driving plate 13. The utility model is characterized in that an electric power, an electric alarm circuit 2, a micro switch 3, a multi-position micro switch 4 and a speaker 5 are arranged in the lock body 6. The utility model has the advantages of non-alarming for original key while alarming for any other key inserted into the lock owing to the use of alarm circuit and multiple switches.

Description

The electronic anti-theft alarming lock

One, technical field

The utility model relates to a kind of safe-guard door lock, and particularly a kind of first wife's key is unblanked noiseless, and the theftproof lock that other key is unblanked automatic warning.

Two, figure viewed from behind technology:

The lock of existing market is various in style, though the lock that has has antitheft or warning function, is not expensive, does not conform to plot exactly, so greatly part all is with general lock.Though these locks are all locked safety cock, one answered one, and the time has been grown, when not bearing in memory, along with present unlawful means is brilliant day by day, the omnipotent king of unblanking exists everywhere, they really are " May all your wish come true ", bring great public hazards to living in peace of people and social security.

Three, summary of the invention:

The purpose of this utility model is improved at shortcoming and problem that background technology exists, provide a kind of safe and reliable, plot rationally, make simple, cost is low, the electronic anti-theft alarming lock of installation aspect.

The technical solution adopted in the utility model is: comprise lock body fixed bolster, lock body, interior outer lock core, dead bolt, dead bolt catch bar, tapered end and tapered end driving chip etc., its characteristics are equipped with warning circuit in lock body, be equipped with on the tapered end driving chip and run groove, microswitch, outer lock core telescopic drive bar, multidigit microswitch and multi-position switch catch bar, Test Switchboard etc.

This is novel owing to above-mentioned original paper is arranged, and has safety, reasonable, reliable, the advantage of warning automatically but not first wife's key is unblanked.

Four, description of drawings

Fig. 1 is a structure chart of the present utility model

Fig. 2,3,4,5, the 6th, accompanying drawing

Fig. 7 is a circuit diagram of the present utility model

Five, the specific embodiment

Below in conjunction with figure and embodiment the utility model is further specified:

As can be seen from Figure 1, the utility model structure is phase-locked together with existing masses, lock body 6 is equally arranged, lock core 10, tapered end 8, tapered end driving chip 7, dead bolt 9, dead bolt catch bar 16, fixing hole 12, safe driving chip 13 etc., different is that battery 1 is housed on lock body 6, warning integrated circuit 2-IC, microswitch 3-K1 runs groove 15, microswitch catch bar 14, loudspeaker 5, multidigit microswitch 4-K2, multidigit microswitch catch bar 11, external lock core body 20 (Fig. 2), core body is regulated overcoat 21, outer lock core door 22, the outer lock core catch bar 23 that stretches, flexible catch bar reset tension spring 24 and spy put key (Fig. 6), test button 51 (Fig. 5) etc.

As can be seen from Figure 4, this novel lock has been prepared a lock body pad, earlier this pad of dress fixing after, again lock body is screwed on the lock pad, so that the circuit elements device is played, damaged in welding, sled and dismounting is easy to maintenance.

Using method: when insertion key 61 opens the door, driving chip 7 is subjected to the effect of key 61, lock core 10 and tapered end driving chip 7 is moved to the left, owing to there is fine motion to open the effect of catch bar 14, O point Fig. 3 slides to B from A, microswitch 3 conductings during to the B point, multidigit microswitch 4, be subjected to catch bar 11, and catch bar is subjected to lock core 10, lock core 10 to be subjected to the effect of key 62, and this switch is in open circuit, and whole warning circuit is in static.When tapered end driving chip 7 again when moving left.The O point is slided to C by B, when the O point arrived C, tapered end 8 end faces were parallel with the lock body edge, this Men Kekai, in the time will locking a door, sheet 7 moved right when tapered end drove, and the O point drops in the CA groove, because dark (Fig. 3) B ' of C is shallow, the O point only may be slided to A by C, when O slided into the A point, because the dark C ' of A is shallow, the O point only may be slided to B by A., unblank, just by A → B → C → A slip that circulates, as long as first wife's key is drawn together in lock core and can be rotated, multi-position switch is at this moment opened a way all the time for locking, O point, circuit is static all the time like this.

And in key does not insert lock core the time, though the multidigit microswitch is conducting, microswitch is an open circuit, and entire circuit also is static.

When in case non-first wife's key insertion lock core is unblanked, the length of key, spoon 62 (Fig. 6) is difficult to and first wife's striking resemblances, long, short slightly slightly, the multidigit microswitch all can conducting, as long as tapered end driving chip motion, microswitch conducting, alarm will be sent a burst of sharp-pointed chimes of doom, have so just reached the purpose of burglar alarm.

Test Switchboard 51-K3 (Fig. 5) is housed on lock body,, will sends sharp-pointed chimes of doom as long as push Test Switchboard aside, but the quality of user's running check circuit like this.

Claims
