Abstract
The utility model discloses a key alarm, comprising a lock body, a battery, a delayer, an alarm device and a sensing device. One end of the delayer is connected with the battery, and the alarm device is connected with the delayer with which the sensing device is connected; the sensing device and the delayer are respectively arranged inside the lock body; the alarm device is arranged on the lock body; the battery is arranged on the lower end of the lock body; and the whole circuit device is arranged inside the lock body. The utility model resolves the problems that the key is often left in the lock when closing and opening the door, thus preventing the circuit from being broken down, prolonging the service life, having the function of voice and light alarm and being suitable for the old and the aurally handicapped.
Description
Technical field
A kind of alarm that the utility model relates to, in particular a kind of key is forgotten the key alarm of taking.
Background technology
In daily life, people open door or shut a back key sometimes and forget and locking, and are so very dangerous, stayed the opportunity of theft to the thief, and the being seen alarm in market can not head it offs.
" a kind of door key protector " of existing Chinese patent application number 01272503; this protector have infrared rays eh, emission induction installation and warning device constitute; in establish the infrared detection circuit the infrared emission induction installation be installed on the door-plate outside; it is infrared to pass lock core to ray; in be provided with delayed alarm circuit warning device be installed on the door-plate inboard, infrared circuit is connected with the delayed alarm circuit holding circuit.When door key is forgotten to pull out, acousto-optic warning be can in time send,, the various losses and the unsafe factor that cause because of maloperation avoided for people provide safeguard protection.But its complex structure, and whole device makes external circuitry break down outside lock body easily, its application life is short.
Summary of the invention
The utility model has overcome above-mentioned shortcoming, and the key alarm of a kind of good warning effect, simple in structure and long service life is provided.Prevent that key from forgeing in lock.
To achieve these goals, the utility model is to realize by the following technical solutions:
The key alarm comprises lock body, battery, delayer, warning device, and an end of described delayer links to each other with battery, and described warning device links to each other with delayer, it is characterized in that, also comprises an induction installation, and described induction installation links to each other with delayer; Described induction installation and delayer are separately positioned in the lock body, and described warning device is arranged on the lock body, and described battery is arranged on the lock body lower end, and the entire circuit device is arranged in the lock body, have avoided the generation of complicated circuit fault.
According to above-mentioned described key alarm, wherein, described induction installation is the infrared induction checkout gear, detects the time of key in lock by infrared induction.
According to above-mentioned described key alarm, wherein, described induction installation is provided with a pressure sensor in being, by key touch pressure sensor pressure, detect the time of key in lock.
Also be provided with warning lamp on lock body, this warning lamp is a light emitting diode, and described warning lamp connects timer, and this warning lamp plays the effect of prompting, by the warning function of warning lamp, is convenient to the aurally handicapped and finds.
Operating principle of the present utility model is, signal by the induction installation induction sends timer to, timer is according to the predefined time, judge the time of key in lock, when surpassing predefined time, timer is connected warning device, the warning device caution that begins to sound, and the while warning lamp dodges.When not reaching Preset Time, warning device and warning lamp are in closed condition.
The utility model is by installing induction installation and alarming device, avoided open and close door knob key to forget defect in lock, the each several part circuit of this device all is arranged in the lock, prevented the generation of connecting circuit fault, increased application life, have the effect of acousto-optic warning, and be applicable to old, aurally handicapped.
Description of drawings
Fig. 1 is a fundamental diagram of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to figure 1, the key alarm comprises lock body, battery, delayer 2, warning device 4, links to each other with battery at an end of delayer 21, and described warning device 4 links to each other with delayer 2, is provided with loudspeaker in this warning device 4, plays the effect of caution by loudspeaker.Also comprise an induction installation 1 in lock body, this induction installation 1 can be infra-red ray detection device, detects the time of key in lock by infrared induction; Also can be pressure sensor; By key touch pressure sensor pressure, detect the time of key in lock.This induction installation 1 links to each other with delayer 2; Induction installation 1 and delayer 2 are separately positioned in the lock body, and warning device 4 is arranged on the lock body, and described battery is arranged on the lock body lower end, and the entire circuit device is arranged in the lock body, have avoided the generation of complicated circuit fault.
In the utility model, also install on lock body and be provided with warning lamp 3, this warning lamp 3 is a light emitting diode, and described warning lamp 3 connects timer 2, and this warning lamp 3 plays the effect of prompting, by the warning function of warning lamp 3, is convenient to old, aurally handicapped's discovery.
When the utility model uses, if key is in unblanking, key touches the induction installation 1 that is arranged on the fore shaft place, and induction installation 1 starts timer after sensing signal, by induction installation 1 signal of induction is sent to timer 2 again, timer 2 is judged the time of key in lock according to the predefined time, when surpassing predefined time, timer 2 is connected warning device 4, warning device 4 caution that begins to sound, simultaneously, warning lamp 3 dodges.When not reaching Preset Time, warning device 4 and warning lamp 3 are in closed condition.
The utility model is by installing induction installation 1 and warning device, avoided open and close door knob key to forget defect in lock, the each several part circuit of this device all is arranged in the lock, prevented the generation of connecting circuit fault, increased application life, effect with acousto-optic warning is applicable to old, aurally handicapped.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
