Description
Technical field
The utility model relates to a kind of lockset designing technique, particularly a kind ofly prevents from forgetting the alarm set pulling key.
Background technology
In society, people's rhythm of life is more and more faster, so busy that to attend to one thing and lose sight of another; The elderly has a bad memory again, forgets things well.Their door of often coming in and going out, key is inserted in to forget just to extract in lockhole and leaves, and brings opportunity to offender.Similar forget to pull key cause family's property theft case to happen occasionally, and more and more serious.For better defence larceny case occurs, in continuous design, some novel can prevent stolen lockset to people, for example Chinese patent " the sounding key ring " (patent No.: 201120350009.7), this patented technology relates to one can either facilitate, promptly search out key, prevent loss, there is again the sounding key ring of decoration function, it comprises key chain, signal projector, on described key chain, be provided with signal recognition and sounding apparatus, advantage is: can help people to search out quickly and easily key, thereby avoid key to lose the embarrassment of bringing; And for example Chinese patent " with the door lock of the alarm set " (patent No.: 201220113486), this patented technology relates to a kind of door lock with alarm set, in described door lock, be provided with a vibration inductive device, described vibration inductive device is connected with a sound-producing device, this patented technology has solved and in prior art, has lacked a kind of problem that can remind user to lock a door, by induction installation is set in door lock, make to detect the vibrations of user in the time of switch gate, induction installation control sound-producing device sounding, reminds user not neglect locking the door in the time going out; And for example Chinese patent " prevent forget to pull key door lock " (patent No.: CN99207423.1), this patented technology provides a kind of door lock of forgetting to pull key of preventing, it is to lock and increased a dead bolt at existing valve, and changes driver blade fixing tapered end into movably mode.When people forget and pull key, newly-increased dead bolt is to stretch out outside lock body, and a pass not go up at closing time, thereby reminds people to pull key, and after key is pulled out, it is interior and do not affect and close the door that dead bolt is just regained lock body, effectively improved anti-theft and the security of door lock.
Above-mentioned these new-type locksets, although can prevent key loss, the user that can remind who has that have do not neglect locking the door in the time going out, particularly " prevent forget to pull key door lock " can prevent that people from forgetting and pulling key at closing time, and have simple in structure, cost is low, anti-theft and security that lockset uses are effectively improved, but these patented technologies all need to change existing lock structure, and the complicated structure of repacking, also inconvenience is installed, has affected the convenience of unblanking normally and locking use.
Utility model content
In order to solve the existing the problems referred to above of prior art, in particular for solving and forgetting to pull key and cause household safe potential problem, the utility model provides a kind of alarm set (claiming again: forget the prompting treasured pulling key) pulling key that prevents from forgetting, it exceedes setting-up time and forgets while pulling key after people open the lock with the key, can send in time alarming prompt sound, remind people to pull up in time key, avoid stolen phenomenon to occur.
Technical solutions of the utility model are as described below: a kind ofly prevent from forgetting the alarm set pulling key, it is characterized in that: it comprises and is arranged at magnetic devices on the key and is arranged at the delayed alarm circuit on lockset; Described delayed alarm circuit comprises power supply, magnetic control trigger switch K1, single-chip microcomputer U1, triode N1 and warning acoustical generator L1, described magnetic control trigger switch K1 is connected between the positive pole of power supply and the trigger pip input end of single-chip microcomputer U1, the power supply signal input end of single-chip microcomputer U1 is connected with the positive pole of power supply, the alarm signal output ends of single-chip microcomputer U1 is connected with the base stage of triode N1, the emitter of the earth terminal of single-chip microcomputer U1 and triode N1 is all connected with the negative pole of power supply, and described warning acoustical generator L1 is connected between the collector of triode N1 and the positive pole of power supply; The installation site of described magnetic control trigger switch K1 on lockset meets the following conditions: in the time that the lock core hole of key insertion lockset puts in place, magnetic control trigger switch K1 can be in attracting state under the magnetic action of magnetic devices, extract after the lock core hole of lockset when key, magnetic control trigger switch K1 resets to off-state.
Described single-chip microcomputer U1 is in dormant state in the time that its trigger pip input end is not received the trigger pip of magnetic control trigger switch K1 adhesive, and alarm signal output ends output high level signal is to the base stage of triode N1; Described single-chip microcomputer U1 is waken up receive the trigger pip of magnetic control trigger switch K1 adhesive at its trigger pip input end after, and postpone setting-up time by alarm signal output ends output low level signal the base stage to triode N1.
The principle of work of the utility model technique scheme is described as follows: due to magnetic devices being set on the key, delayed alarm circuit is set on lockset, the lock core hole that key inserts lockset just in time can make magnetic control trigger switch K1 in attracting state to bit position, after key is extracted, magnetic control trigger switch K1 disconnects.When key inserts after the lock core hole of lockset, the magnetic devices that utilization is arranged on the key makes magnetic control trigger switch K1 adhesive, on-delay warning circuit, utilize the single-chip microcomputer U1 delay setting-up time of delayed alarm circuit to output signal to the base stage of triode N1, make triode N1 conducting, alerting signal is sent in the acoustical generator L1 that makes to report to the police energising.If at any time, key is extracted (for example key be inserted in time on the lock core hole of lockset while not reaching setting-up time key extract, or key is inserted in time on the lock core hole of lockset and exceedes setting-up time and after trigger alarm, just extract key), magnetic control trigger switch K1 just disconnects, and just can not send alerting signal.
The utility model exceedes setting-up time after people open the lock with the key to be forgotten while pulling key, can send in time alarming prompt sound, reminds people to pull up in time key, avoids stolen phenomenon to occur.Compared to prior art, the utility model also has the following advantages:
(1) without changing existing lock structure, install additional easy;
(2) utilize the magnetic switch on magnetic devices and delayed alarm circuit on the key to trigger, close delayed alarm circuit, highly sensitive, operate practical and convenient;
(3) time delay alarm design (time delay for example can be set about 8 seconds), neither impact is unblanked normally, is locked, and can forget to extract in 2,3 seconds of key owner again and remind in time;
(4) install material price additional cheap, be suitable for producing and promote.
