Abstract
The utility model discloses an improved lock, in particular to an intelligent theft protection lock. The intelligent theft protection lock consists of a lock body 1 and a lock tongue 2. The exterior of the lock body 1 is provided with an external shell 3; an alarm device 4 is arranged between the lock body 1 and the shell 3. The alarm device 4 consists of a metal induction piece 5 and an alarm circuit diagram 6; the metal induction piece 5 is contacted with the shell 3. The lock with the structure can emit alarm sound when being knocked or picked, which really exerts theft protection function. The utility model can be widely applied to the protection in safety theft protection field.
Description
The utility model relates to a kind of improvement of lock, a kind of specifically intelligent anti-theft lock.
At present, the intelligent anti-theft lock that adds intelligent alarm device is a lot of locking, but all be that lock is directly installed on the door, promptly lock and door are one, and add also not having of warning device in single locking, in the city especially in vast rural area, this single lock is used still more widely, but the lock of this structure is easy to be prized, and can not play real antitheft effect, brings many inconvenience for people's life.
The purpose of this utility model just is to provide a kind of intelligent anti-theft lock that can really play antitheft effect.
The utility model is achieved in that this intelligent anti-theft lock, is made up of lock body, dead bolt, is provided with a shell in the outside of lock body, is provided with a warning device between lock body and the shell.Warning device is made of metal sensing chip and alarm circuit figure, metal sensing chip and housing contacts.
The utility model has the advantages that: being locked in when being beaten or being prized of this structure can be sent chimes of doom, plays real antitheft effect.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is the utility model cross-sectional schematic.
Accompanying drawing 2 is the utility model warning device schematic diagram.
In conjunction with the accompanying drawings 1, this intelligent anti-theft lock is made up of lock body 1, dead bolt 2, is provided with a shell 3 in the outside of lock body 1, is provided with a warning device 4 between lock body 1 and the shell 3.Warning device 4 is made of metal sensing chip 5 and alarm circuit Fig. 6, and metal sensing chip 5 contacts with shell 3.
