Abstract
The utility model discloses a novel anti-theft lock core which comprises a lock core consisting of a lock shell and a lock cylinder, wherein a metal anti-drill pin is inserted and sheathed into one marble hole of the lock shell, and an external control device is used for controlling the lifting of the metal anti-drill pin. When the metal anti-drill pin is in the locking state (that is, the metal pin is inserted and sheathed in the lock cylinder), the lock cylinder can not be rotated for unlocking by utilizing a key matched with the novel anti-theft lock core, or be rotated for unlocking by a passkey or a small metal rod, and the anti-theft lock core can not be unlocked even by utilizing an electric drill, a hammer and other tools for damaging the lock core in a forced manner as long as the metal pin is not separated from the marble hole and the lock cylinder, thereby effectively improving the anti-theft function of a lock. The lock cylinder can only be rotated for unlocking by utilizing the matched key under the condition that the metal anti-drill pin is in the opening state (that is, the metal pin is positioned in the marble hole and separated from the lock cylinder).
Description
Technical field
The utility model relates to the lock technology field, more specifically to a kind of novel anti-theft technology.
Background technology
Existing lock a little less than the anti-theft feature a surname, utilizes master key or tiny Metallic rod all than being easier to lock to be opened, if utilize instruments such as electric drill, iron hammer to destroy the then easier unlatching lock of lock core by force, therefore is necessary existing lock is improved.
The utility model content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of novel anti-theft lock core, and it effectively raises the anti-theft feature of lock.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of novel anti-theft lock core, comprise the lock core of being made up of lock housing and lock gall, be inserted with the metal anti-drill pin in one of them pellet shot from a slingshot hole of described lock housing, the metal anti-drill pin is controlled lifting by external control device.
Moulding step on the described metal anti-drill pin is fixed with involucrum on the lock housing, form through hole on the involucrum, and the step bottom of metal anti-drill pin passes through hole and step resists on involucrum.
Described metal anti-drill pin is the magnetic pin, and external control device is the electromagnet by control circuit control.
Described external control device is meshed with worm screw by the rotation of stepper motor drive worm gear, worm gear, and worm screw and metal anti-drill pin are fixed together.
The utility model is compared the advantage that is had with prior art: the utility model is provided with the metal anti-drill pin in one of them pellet shot from a slingshot hole of existing lock core, the metal anti-drill pin is controlled lifting by external control device, when metallic pin is in lockup state when entering in the lock gall (be metal anti-drill pin sleeve), utilizing supporting key also can't rotate lock gall unblanks, master key or tiny Metallic rod then more can't be rotated lock gall and be unblanked, even utilize electric drill, instruments such as iron hammer destroy lock core by force, if metallic pin does not break away from from pellet shot from a slingshot hole lock gall, then still can't unblank, effectively raise the anti-theft feature of lock.Have only when metallic pin is in opening when breaking away from (metal anti-drill pin be positioned at the pellet shot from a slingshot hole and), just can utilize supporting key rotation lock core to unblank with lock gall.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of embodiment one.
Fig. 2 is the schematic perspective view that the pellet shot from a slingshot hole cooperates with metallic pin.
Fig. 3 is the decomposing schematic representation of embodiment one.
Fig. 4 is the structural representation of embodiment two.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment one, sees shown in Fig. 1 to 3: a kind of novel anti-theft lock core, comprise the lock core of forming by lock housing 11 and lock gall 81, and be inserted with metal anti-drill pin 2 in one of them pellet shot from a slingshot hole 111 of lock housing 11, metal anti-drill pin 2 is by external control device 3 control liftings.
Moulding step 21 on the metal anti-drill pin 2 is fixed with involucrum 4 on the lock housing 11, form through hole 41 on the involucrum 4, and step 21 bottoms of metal anti-drill pin 2 pass through hole 41 and step 21 resists on involucrum 4.
Metal anti-drill pin 2 is the magnetic pin, and external control device 3 is the electromagnet by control circuit control.
Embodiment two, see shown in Figure 4: drive transmission mechanism 32 by control circuit control motor 31 and rotate, worm gear 32 is meshed with worm screw 33, worm screw 33 control metal anti-drill pin motions.All the other are with embodiment 1.
The utility model is provided with metal anti-drill pin 2 in one of them pellet shot from a slingshot hole 111 of existing cylinder lock, metal anti-drill pin 2 is by external control device 3 control liftings, when metal anti-drill pin 2 is in lockup state when entering in the lock gall 8 (be metal anti-drill pin 2 sleeves), utilize supporting key also can't to unblank by rotational lock core, master key or tiny Metallic rod then more can't be unblanked by rotational lock core, even utilize electric drill, instruments such as iron hammer destroy lock core by force, if metal anti-drill pin 2 does not break away from from lock gall 8 interior 11, then still can't unblank, effectively raise the anti-theft feature of lock.Have only when metal anti-drill pin 2 is in opening when breaking away from (metallic pin 2 be positioned at pellet shot from a slingshot hole 111 and), just can utilize supporting key turns lock gall to unblank with lock gall 8.
Metal anti-drill pin 2 can be controlled locking and opening by a variety of modes, for example utilize electromagnet and magnetic metal defence lead plug 2 to realize locking or unlatching among the embodiment one, the lifting that and for example utilizes worm screw 33 to drive metal anti-drill pin 2 among the embodiment two realizes locking or unlatching.
