Abstract
The invention discloses a doorlock, and particularly relates to an antitheft doorlock which comprises a casing, a handle arranged on the side face of the shell and a mobile lock cylinder, wherein the handle is connected with the mobile lock cylinder by a spring mechanism, and the casing is internally provided with a cavity allowing the mobile lock cylinder to move. The antitheft lock cylinder also comprises an alarm device which is arranged in the cavity and comprises a displacement sensor, a signal processor and a buzzer, and the signal processor is connected with the displacement sensor at the input end and connected with the buzzer at the output end. Whether the antitheft doorlock disclosed by the invention is opened or not is judged by measuring the moving distance of the mobile lock cylinder, and alarming is performed when the doorlock is opened, thus improving the antitheft performance of the doorlock.
Description
Technical field
The invention discloses a kind of door lock, especially a kind of safe-guard door lock.
Background technology
For the door lock that key and flexible lock core are arranged, door lock is under the situation of key correspondence, and the pulling flexible lock core can open the door, and such door lock theftproof is relatively poor.Except the key correspondence, increase some anti-theft measures again, the defective of avoiding key just can unblank is necessary.
Summary of the invention
Technical problem to be solved by this invention is at the deficiency of above-mentioned background technology, and safe-guard door lock is provided.
The present invention adopts following technical scheme for achieving the above object:
Safe-guard door lock, comprise housing, be arranged on the handle and the flexible lock core of housing side, handle is connected with flexible lock core by spring mechanism, one cavity that supplies flexible lock core to move is arranged in the housing, and described anti-theft lock also comprises the warning device that places in the described cavity, and described warning device comprises displacement transducer, signal processor, buzzer, described signal processor input termination displacement transducer, signal processor output termination buzzer.
Further, in the described safe-guard door lock, signal processor comprises analog-digital converter and comparator, described analog-digital converter input termination displacement transducer, and described comparator input terminal connects described analog-digital converter output, and comparator output terminal connects buzzer.
Further, in the described safe-guard door lock, signal processor is a single-chip microcomputer.
Further, in the described safe-guard door lock, signal processor is a dsp chip.
The present invention adopts technique scheme, has following beneficial effect: by measuring the displacement of flexible lock core, judge whether door lock is opened, and report to the police when door lock is opened, improved the theftproof performance of door lock.
Description of drawings
Fig. 1 is the safe-guard door lock schematic diagram.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
As shown in Figure 1, safe-guard door lock of the present invention comprises housing, is arranged on the handle and the flexible lock core of housing side, and handle is connected with flexible lock core by spring mechanism, and a cavity that supplies flexible lock core to move is arranged in the housing.Anti-theft lock also comprises the warning device that places in the described cavity.Warning device comprises displacement transducer, signal processor, buzzer, signal processor input termination displacement transducer, signal processor output termination buzzer.Signal processor comprises analog-digital converter and comparator, analog-digital converter input termination displacement transducer, and comparator input terminal connects described analog-digital converter output, and comparator output terminal connects buzzer.Signal processor is single-chip microcomputer or is dsp chip.
When the distance that flexible lock core enters lockhole was D, door was locked.Displacement transducer is arranged on the cavity inside that moves for flexible lock core in the housing, by measuring the displacement d of steel flexible lock core at cavity inside, flexible lock core after being converted to the signal of telecommunication, the displacement d of cavity inside is transferred to signal processor, signal is handled the signal of telecommunication that receives is done analog-to-digital conversion process, compare with D, when the displacement d=D/2 of flexible lock core, judge that door lock is opened at cavity inside, buzzer is blown a whistle, and Alarm door lock is opened.
In sum, safe-guard door lock of the present invention by measuring the displacement of flexible lock core, judges whether door lock is opened, and reports to the police when door lock is opened, and has improved the theftproof performance of door lock.
