Description

A kind of mixed type alarming lock core

[technical field]

The utility model relates to a kind of lock, particularly a kind of structure of the antitheft sylinder that can report to the police automatically.

[background technology]

Cylinder lock is present credit and the most mechanical lockset of consumption, and the cylinder locks that circulate in a large number on the society are mostly merely based on copper marble, iron pellet shot from a slingshot or magnetic marble, cooperation between its pellet shot from a slingshot mostly is the cooperation of same material attribute greatly, its shortcoming is to be easy to utilize master key to stir pellet shot from a slingshot at lock core marble make pellet shot from a slingshot be pushed away the block resistance position in moment to unblank, and is causing lock not open or lock without key and can open because of the pellet shot from a slingshot demagnetization probably based on the lock core of magnetic marble.

[utility model content]

The technical problems to be solved in the utility model, be at above-mentioned shortcoming provide a kind of safe, be difficult for by unnormal unlocking and the anti-theft billiards lock construction that can report to the police automatically.

The utility model is to realize like this, a kind of mixed type alarming lock core, comprise lock housing and lock core rotor, be equiped with the lock core rotor that is cylindrical shape in the lock housing, be provided with keyhole in the middle of the lock core rotor, the lock housing sidewall is provided with some pellets shot from a slingshot hole, corresponding being provided with from sidewall connects pellet shot from a slingshot hole to keyhole on one side sidewall of lock core rotor, be placed with the first floor pellet shot from a slingshot successively in the pellet shot from a slingshot hole on lock core rotor and the lock housing, second layer pellet shot from a slingshot, spring and seal steel ball, wherein the height of first floor pellet shot from a slingshot is just equal with the outer wall of lock core rotor after key inserts keyhole, at least one iron pellet shot from a slingshot is set in the described first floor pellet shot from a slingshot, all the other are copper marble, iron pellet shot from a slingshot with first floor in the second layer pellet shot from a slingshot is set to magnetic marble accordingly, all the other are copper marble, it is characterized in that: be placed with the first floor pellet shot from a slingshot successively in the pellet shot from a slingshot hole on lock core rotor and lock housing, second layer pellet shot from a slingshot and travel switch, described second layer pellet shot from a slingshot is not just touched travel switch after key inserts keyhole, travel switch is circumscribed with burglar alarm by connecting line.

The utility model can further be specially:

Place a steel ball on the first floor pellet shot from a slingshot in first pellet shot from a slingshot hole from inside to outside on the described lock core rotor sidewall, this steel ball adds that the height of first floor pellet shot from a slingshot is just equal with the outer wall of lock core rotor after key inserts keyhole.

Pellet shot from a slingshot hole on the described lock core rotor sidewall also is provided with the reaming that is slightly larger than the pellet shot from a slingshot hole near an end of second layer pellet shot from a slingshot.

Described burglar alarm connects chimes of doom IC (integrated circuit) by MCU (microcontroller) chip, is connected to external loudspeaker behind the power amplifier by chimes of doom IC again.

After described MCU also connected a voice IC, voice IC was connected to external loudspeaker behind the power amplifier again.

Also be provided with anti-trimming between described travel switch and the burglar alarm.

The utility model adopts above-mentioned structure, structure is in the past compared has following advantage: adopt iron pellet shot from a slingshot and magnetic marble to combine, the principle of utilizing iron pellet shot from a slingshot and magnetic marble to inhale mutually, when unnormal unlocking, can prevent first floor pellet shot from a slingshot and the disengaging of second layer pellet shot from a slingshot when techno-shock, play antitheft effect; Increased the structure of reaming, can be when unnormal unlocking, make the opener be difficult for finding contiguous sense between second layer pellet shot from a slingshot and the lock core rotor pellet shot from a slingshot hole, prolong the unnormal unlocking time, play antitheft effect; Increase travel switch and external anti-theft device, utilize machinery and electronics to combine, directly electronic product is acted on lock core, when pseudo-key (referring to non-matching key or other instruments) is inserting in the keyhole, can trigger travel switch, and signal is transferred to anti-theft device by data wire, and produce voice suggestion or alarm, reach the effect of burglar alarm.
