Description
The utility model relates to a kind of lock core that is used for door lock, especially can pick-proof, anti-drilling, anti-ly unload, the totally-enclosed box hat five anti-alarm door lock cores of anti-saw, burglar alarm.
In the used lock core of front door lock, adorn four copper marbles; key is S-type; preparation easily; lock core adopts copper or aluminium, and its material is softer, may be destroyed once boring with drill bit; there is not firm protective device in the dead ahead of lock core; thereby use such lock core, and often causing opportunity to the thief, theftproof performance is poor.
The purpose of this utility model is that a kind of totally-enclosed box hat five anti-alarm door lock cores will be provided, and it can prevent to go into interior possibility from the destruction door lock effectively.
The purpose of this utility model is achieved in that an anti-drilling alloy protecting body of band cross-hole is housed in the lock body circular hole; be installed in the cover micro pressure bearing upper pressure center hole; being with the lock core body of cross bore to fit with bottom pearl dish and centre is in the same place; the outer side plane of lock body studs with a pick-proof metal sheet; in the translot of symmetry spring and pellet shot from a slingshot are housed in the lock core body cross bore; vibrating sensor is equipped with in the lock core body bottom, and is connected to warning device.Therefore this lock core has pick-proof, anti-drilling, the anti-function of unloading, preventing feedback, burglar alarm, has played the strick precaution protective effect.
The totally-enclosed box hat five anti-alarm door lock cores that provided by the utility model are applicable to all safe-guard door locks; the door lock of resident's door lock and automobile, safety cabinet, national treasury, file store particularly; be a kind of desirable burglar alarm protective device, it has actual use value and society generalization meaning.The existing producer that produces lock can produce under the condition that does not increase investment and equipment.
Below in conjunction with drawings and Examples the utility model is illustrated in detail.
Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is a vertical view of the present utility model
Fig. 3 is the just flat figure of key of the present utility model
Fig. 4 is a key side view of the present utility model
Among the figure: 1 lock body, 2 anti-drilling protectives, 3 pressure bearings, 4 lock core bodies, 5 keys, 6 pellets shot from a slingshot, 7 springs, 8 anti-skid plates, 9 vibrating sensors, 10 switches, 11 batteries, 12 alarms, 13 loudspeaker, 14 transmission bars.
As Fig. 1; shown in 2; totally-enclosed box hat five anti-alarm door lock cores; it is by lock body (1); lock core body (4); pellet shot from a slingshot (6); spring (7) assembling constitutes; it is characterized in that being equipped with in box hat lock body (1) circular hole a band anti-drilling alloy protecting body of cross-hole (2); be installed in cover micro pressure bearing (3) the upper pressure center hole; being with the copper lock core body (4) of cross bore to fit with bottom pearl dish and centre is in the same place; cross bore copper lock core body (4) and the concentric coupling combination of box hat lock body (1); the anti-drilling alloy protecting body of cross bore (2) is closely chimeric with pressure bearing (3); form one and can in lock body (1), execute the anti-drilling freely independent integral body of commentaries on classics; hidden in lock body (1); the outer side plane of lock body (1) studs with a pick-proof monolithic metal (8), is welded as a whole.Insert in 16 symmetrical in lock core body (4) cross bore of key (5) translots 16 springs (7) and 16 steel pellets shot from a slingshot (6) are housed.In lock body (1) circular hole, in the concave volume of copper lock core body (4) bottom vibrating sensor (9) is housed, vibrating sensor (9) draws and connects two leads, one joins with battery (11), the centre is provided with manual switch (10), another root connects alarm (12), and alarm (12) links to each other with loudspeaker (13).Key shown in Fig. 3,4 (5) is the cross longitudinal bodies, symmetrical four side edge indention.Under the normal condition; key (5) must just can enter cross bore copper lock body (4) by the band anti-drilling alloy protecting body of cross bore (2) and go up pellet shot from a slingshot (6) promotion spring (7) return; key (5) just can be opened lock core body (4) rotation, drives transmission bar (15), opens door lock and in going into.Otherwise; thief's crime time is hurry; can't use tamper tool at short notice; cutting or dismantle welding-on has lock body of pick-proof iron plate (8) (1) and alloy protecting body (2); has only the wimble of using; drill bit touches the alloy protecting body (2) of band cross bore; firmly light brill is motionless; the pressure that firmly heavy protective (2) is subjected to drill bit forces the also and then rotation of the moving pearl dish of pressure bearing (3) upper pressure dribbling; bore not enter, or insert, do not reach equally in the cross bore copper lock core (4) with the substitute that is difficult to preparation cost lock core (4) key; can't make lock core body (4) rotation, open door lock.As still unwilling to give up, to pound firmly with strength, crash shock sensor (9) is delivered to alarm (12) by switch (10) battery (11) conduction, and the loudspeaker (13) that link to each other begin to call out.
