Abstract
The utility model relates to a door lock capable of reminding people of pulling out a key. The door lock comprises a lock body and the key, and is characterized in that a contact switch and a sensor are arranged at the rear end or on one side of a lock body keyhole, a light-emitting diode and a buzzer are arranged on a lock body panel, a single chip microcomputer and a battery chamber are arranged in the lock body, and batteries are mounted in the battery chamber. The sensor, the light-emitting diode, the single chip microcomputer and the buzzer are electrically connected with the battery chamber through the contact switch, and the light-emitting diode and the buzzer are controlled to start via the single chip microcomputer. By application of the sensor and the single chip microcomputer, time for inserting the key into the door lock is controlled, once a set time is exceeded, the buzzer gives out a warning sound to remind people of taking off the key left on the door lock, and accordingly safety of the door lock is improved.
Description
Technical field
The utility model relates to door and lock product technical field, specifically, is a kind of door lock that can remind people in time to extract key after opening the lock with the key.
Background technology
Key is one of important structure part of lockset.It has often been said and open different locks with different keys.If a people runs into more lockset in live and work, also often have with a big string key.In life, the somebody tends to forget key is pulled out when opening tame door lock or office's door lock, especially is being with thing to go home or when entering office, hurriedly thing is taken into behind the room key given and has been forgotten door and gone up.And these carelessness are utilized by bad people sometimes, and they are had an opportunity to take advantage of.With regard to present door lock, the door lock that can remind people in time to extract key after opening the door also rarely has finding.In some present top restaurants when the door in guest room when not shutting, the alarm of installing door on can timely prompting.After shutting the door, alarm stops to report to the police immediately.Though this also belongs to a kind of of gate inhibition, with door lock one not necessarily, with the door lock of reminding people in time to extract key structural difference is arranged also.Because the importance of door lock and the generality of use have and can remind the door lock that pulls key to house or in demand.
The utility model content
Order of the present utility model is to overcome the deficiency of existing product, provide a kind of and can remind the door lock that pulls key, at door lock sensor and single-chip microcomputer are set, after key inserts door lock, single-chip microcomputer starts timer and begins countdown, if countdown key behind the setting-up time is also stayed in the door lock, buzzer namely sends caution sound, remind people to take the key of forgeing on door lock away, thereby improve the safety of lockset.
For achieving the above object, the utility model has been taked following technical scheme.
A kind of energy is reminded the door lock that pulls key, contain lock body and key, it is characterized in that, a contact-making switch and a sensor are set in the rear end of described lock body keyhole, at lock panel a light emitting diode and a buzzer are set, single-chip microcomputer and battery cavities are set in described lock body, in the described battery cavities battery can be installed; Described sensor, light emitting diode, single-chip microcomputer and buzzer are electrically connected with battery cavities by contact-making switch, by the startup of Single-chip Controlling light emitting diode and buzzer.
Further, described contact-making switch is arranged on a side of described lock body keyhole.
A kind of good effect of the door lock that pulls key of reminding of the utility model is:
By sensor and The application of single-chip computer, the time of inserting key in the door lock is controlled, in case surpass the time of setting, buzzer just sends caution sound, reminds people to take the key of forgeing on door lock away, thereby improves the safety of lockset.
Description of drawings
Fig. 1 is a kind of structural representation that can remind the door lock that pulls key of the utility model.
Fig. 2 is the FB(flow block) that the utility model is electrically connected and signal transmits.
Label among the figure is respectively:
1, lock body; 2, key; 3, sensor; 4, contact-making switch;
5, light emitting diode; 6, single-chip microcomputer; 7, buzzer.
The specific embodiment
Provide a kind of specific embodiment that can remind the door lock that pulls key of the utility model below in conjunction with accompanying drawing, still, enforcement of the present utility model is not limited to following embodiment.
Referring to Fig. 1, a kind of energy is reminded the door lock that pulls key, and constitutes a complete lockset by lock body 1 and key 2, can make the form of structure of existing lockset, and but, described lock body 1 should be done more greatly to hold the content of new construction.Rear end or a side at described lock body 1 keyhole arrange a contact-making switch 4 and a sensor 3, panel at lock body 1 arranges a light emitting diode 5 and a buzzer 7, the shinny of described light emitting diode 5 can directly be shown, also be conducive to the transmission sound of described buzzer 7.In described lock body 1, single-chip microcomputer 6 and battery cavities are set, in the described battery cavities battery can be installed.Described sensor 3, contact-making switch 4, light emitting diode 5, single-chip microcomputer 6 and buzzer 7 can adopt the corresponding product that supply is arranged in the market.Described sensor 3, light emitting diode 5, single-chip microcomputer 6 and buzzer 7 are electrically connected with battery cavities by contact-making switch 4, by the startup of single-chip microcomputer 6 control light emitting diodes 5 and buzzer 7.
Referring to accompanying drawing 2.A kind of energy of the utility model reminds the door lock that pulls key to be electrically connected and the flow process of signal transmission is:
(1) after key 2 inserts the keyhole of lock body 1, the contact-making switch 4 that is arranged on keyhole rear end (or a side) is activated, power supply is switched on, sensor 3, single-chip microcomputer 6 enter duty, single-chip microcomputer 6 is accepted the signal that sensor 3 spreads out of and is begun countdown (setting-up time of countdown was generally 60 seconds) and control light emitting diode 5 beginnings shinny, key 2 is boxed out the time in case above the time limit of setting, and buzzer 7 just sends caution sound, and light emitting diode 5 begins flicker simultaneously.
(2) after key 2 is extracted the keyhole of lock body 1, contact-making switch 4 cuts out, and sensor 3, single-chip microcomputer 6, light emitting diode 5 are because outage quits work, and the countdown of single-chip microcomputer 6 also returns 0.
Claims (2)
1. can remind the door lock that pulls key for one kind, contain lock body (1) and key (2), it is characterized in that, in the rear end of described lock body (1) keyhole a contact-making switch (4) and a sensor (3) are set, at lock body (1) panel a light emitting diode (5) and a buzzer (7) are set, single-chip microcomputer (6) and battery cavities are set in described lock body (1), in the described battery cavities battery can be installed; Described sensor (3), light emitting diode (5), single-chip microcomputer (6) and buzzer (7) are electrically connected with battery cavities by contact-making switch (4), by the startup of single-chip microcomputer (6) control light emitting diode (5) and buzzer (7).
2. a kind of energy according to claim 1 is reminded the door lock that pulls key, and it is characterized in that described contact-making switch (4) is arranged on a side of described lock body (1) keyhole.
