Description

Lockset warning device

Affiliated technical field:

The utility model belongs to commodity, particularly be can be at broken lock, the lockset warning device of reporting to the police when forcing open the door.

Background technology:

Door lock be magnetic lock, cylinder lock, mechanical lock, Fingerprint Lock, coded lock or the like, in order to increase its safety, many improved newly locking out are now arranged again, but it is safe and secret always relative, the simply broken lock of some stealer is forced open the door, and lock has also worked with regard to difficulty, has just occurred warning device in this case, inform people robber person presence with the various signals of warning, sound, please fast messenger's protection.But the broken lock that existing alarm has is just reported to the police, and having plenty of forces open the door just reports to the police, and the stolen easily person who has finds and abolished alarm, unsatisfactory part is respectively arranged.

Summary of the invention:

Lockset warning device is made up of the warning device in the lock body keyhole, warning device in the dead bolt and the shared sounding of aforementioned two parts circuit three parts of warning;

Warning device design feature in the lock body keyhole is: establish locating hole and corresponding lock core marble hole on the key, lock marble hole is corresponding, be respectively equipped with copper marble in lock core marble hole, the lock marble hole, and lock body copper marble hole collar extension and electric switch connect, the circuit electrical coupling of warning of switch and sounding.When correct key inserted, because copper marble in the corresponding lock core marble hole, lock marble hole and on the key locating hole coupling, electric switch was not squeezed, not conducting of circuit, also just not sounding warn; If pseudo-key is when inserting, although but magnetic emulation reach a standard, the pellet shot from a slingshot hole does not match in locating hole on the key and core, the body, copper marble external pressure in core, the body, switch is touched, circuit turn-on, sounding is warned.

Warning device design feature in the dead bolt is: establish groove in the dead bolt, establish spring in the groove, client link switch in the spring; When lock cut out, the protrusions press snap switch that the forward recess of dead bolt is stuck in the attachment (doorframe) disconnected not conducting of circuit, not sounding; When outside destroy attachment (doorframe), latch bolt spring ejects, electrical switch closes, and circuit turn-on, sounding is warned.

Advantage of the present utility model clearly, this lock has adopted the principle of former mechanical billiard to design in conjunction with the magnetic marble principle, its design focal point is to increase the antitheft parameter of mechanical billiard on the basis of magnetic lock, make this lock really play antitheft effect, on the best theoretical value strong point of mechanical billiard, add a power switch in addition, make this lock improve antitheft parameter greatly, use pseudo-key to be difficult to open; This lock has increased the device of automatic warning again, and not only extremely difficulty is unblanked, and breaks lock, forces open the door and also can report to the police automatically.Warning function can design by requirement of client, has reached best anti-theft effect.This technology can be used in the safe-guard door lock class, safety cabinet lock class, and the automotive lock class, some special lock classes of using of lock for motorcycle, its processing technology is convenient and simple, and production scale is changeable.In pseudo-key insertion keyhole, acoustical generator will be warned by sounding; When the stranger forced open the door lock by force, dead bolt was deviate from, and acoustical generator also can be warned by sounding; So be that dual fail-safe is reported to the police, be skillfully constructed, structure is uncomplicated, and cost is not high, is easy to promote.

The specific embodiment:

As shown in Figure 1, the part that the utility model is identical with existing magnetic lock is: fixing magnetic patch 2 on the key 1, and establish respectively on lock body 5, the lock core 6 and be provided with lock body magnetic marble 3, lock core magnetic marble 4 at least in 2 pellet shot from a slingshot holes and each hole, and correspondingly separately connect combination; On the key 1 fixedly magnetic patch 2 cooperate with lock body magnetic marble 3, lock core magnetic marble 4, and utilize magnetic force to slide mutually, control the motion that its workload reaches lock core 6 and lock body 5 by profile, the size dimension of magnetic marble; The hole is sealed with mounting 8 in magnetic marble hole 7; The utility model and existing magnetic lock part inequality is: key 1 sidewall is established key pins locating hole 12; When key 1 inserts in the keyhole, key pins locating hole 12 is complementary with corresponding pellet shot from a slingshot hole 11, pellet shot from a slingshot hole 11 is arranged in lock core 6 and lock body 5, and establish lock core copper marble 9, lock body copper marble 10 in the pellet shot from a slingshot hole 11 respectively, and with 12 interlocks of key pins locating hole, utilize its stroke, reach interlock normally closed switch 13, switch contact 14 is connected, sent pulse signal and reach warning function by

lead

15,16 connection power supplys 17, alarm 18.

Fig. 2 is phonation circuit figure, and acoustical generator 18 1 ends connect normally closed switch 13-1 with lead 16-1 and connect normally closed switch 22 again, again through lead 15 joining power positive poles, power cathode connects acoustical generator 18, form series loop, when normally closed switch 13-1 connected, acoustical generator 18 was with regard to sounding alarm; Acoustical generator 18 1 ends connect normally closed switch 13 with lead 16, connect positive source through lead 15 again, and when normally closed switch 13 was connected, acoustical generator was reported to the police.

As shown in Figure 3, the utility model is also different with the structure of common magnetic lock on dead bolt: just often, dead bolt 20 front ends are established groove 26 and are against on the projection of doorframe, groove is inwardly established pressing plate 23, spring 25 successively, connect Live switch 22 1 ends again, when the broken lock of external force is forced open the door, switch contact and normally closed switch 13 UNICOMs, normally closed switch 13 connects the circuit sounding alarm with lead 16.

The utility model colleague technician can implement.
