Abstract
The utility model relates to a prompting lock. A power supply (1), a switch (2), an electromagnet (3), a protective resistor (4), a stationary contact device (5) and a spring bolt insulation transmission strip (6) are formed into a closed loop by a lead. An armature contact device (9) and the switch (2) are connected in series, are connected in parallel with a circuit formed by the stationary contact device (5) and a keyhole insulation transmission strip (13) and then are connected in a power supply loop connected with a buzzer (10) in series. When a door is opened by a key or locking is not in place, the loop in which the buzzer (10) is located is conducted, and a sound is made by the buzzer to prompt people to pull out the key or lock the door so as to avoid the loss caused to the people because the people forget to pull out the key or the locking is not in place. The prompting lock has low cost, a simple structure and convenience in use and can be widely used for daily life.
Description
Technical field
The present invention relates to a kind of lock, a key was extracted after especially a kind of reminds people was unblanked, and when locking a door the good prompting of door lock was locked.
Background technology
For antitheft, security needs, the exploitation of door lock technology is maked rapid progress, and the anti-theft feature of door lock is gradually improved.But people often forget a key and extract or lock not in place from lock owing to carelessness after unblanking, so even various door locks with high content of technology are installed, the serious consequence that carelessness is caused still is difficult to remedy, therefore a kind of back key of can reminds people unblanking is extracted, and is just necessary the good lock of door lock when locking a door.
Summary of the invention
The present invention's purpose: propose a kind of back key of can reminds people unblanking and extract, when locking a door the good prompting lock of door lock.
In order to realize the invention described above purpose, intend adopting following technology:
The invention is characterized in: power supply, switch, electromagnet, protective resistance, fixedly contact device, dead bolt insulation transmission bar are composed in series the closed-loop path by lead.The series connection of armature contact device, switch again with fixing contact device, circuit that keyhole insulation transmission bar is composed in series and the current supply circuit that is connected in the buzzer of connecting in.One end of dead bolt insulation transmission bar posts conducting strip and with fixedly contact device is relative, the other end is relative with dead bolt; One end of keyhole insulation transmission bar posts conducting strip and with fixedly contact device is relative, the other end gos deep into keyhole.One end of electromagnet is provided with an armature.Described circuit all encases with insulating layer.
Maximum characteristics of the present invention: the present invention is by buzzer call, and reminds people is unblanked, and to extract and point out people to lock not in place for a back key, good door lock.Avoided the loss that causes to people because of " forget and pull key " or " it is not in place to lock ".The present invention is with low cost, and is simple in structure, easy to use, can be widely used in the daily life.
Description of drawings
Accompanying drawing is a schematic diagram of the present invention.
1: power supply; 2: switch; 3: electromagnet; 4: protective resistance; 5: fixing contact device; 6: dead bolt insulation transmission bar; 7: dead bolt; 8: armature; 9: the armature contact device; 10: buzzer; 11: keyhole; 12: insulating layer; 13 keyholes insulation transmission bar; 14: conducting strip.
The specific embodiment
During use, key is inserted keyhole 11 unblanks, keyhole insulation transmission bar 13 is extruded, and makes the conducting strip 14 of keyhole insulation transmission bar 13 1 ends contact the loop conducting of buzzer 10 place with fixing contact device 5, after key is pulled out, keyhole insulation transmission bar 13 separates with fixing contact device 5, gets back to original position, and loop, buzzer 10 place disconnects, stop to pipe, so just can reminds people be extracted by key.When putting in place when locking, dead bolt 7 extruding dead bolt insulation transmission bars 6, dead bolt insulation transmission bar 6 is contacted with fixing contact device 5, the loop conducting of electromagnet 3 place, electromagnet 3 has magnetic, and adhesive armature 8 makes armature 8 separate with armature contact device 9, buzzer 10 place circuit disconnect, and buzzer 10 is not sounded; When locking when not in place, dead bolt insulation transmission bar 6 and fixedly contact device 5 is separately, electromagnet 3 place loop open circuit, electromagnet 3 does not produce magnetic force, thereby adhesive armature 8, and armature 8 contacts with armature contact device 9, the loop conducting of buzzer 10 place, buzzer 10 sound the prompting people lock not in place, door lock is good.In case of necessity, also can directly control the start and stop of buzzer by switch 2.
Claims (1)
1. prompting lock is characterized in that: power supply (1), switch (2), electromagnet (3), protective resistance (4), fixedly contact device (5), dead bolt insulation transmission bar (6) be by lead composition closed-loop path; The series connection of armature contact device (9), switch (2) again with fixing contact device (5), circuit that keyhole insulation transmission bar (13) is composed in series and the current supply circuit that is connected in the buzzer of connecting (10) in; One end of dead bolt insulation transmission bar (6) posts conducting strip (14) and with fixedly contact device (5) is relative, the other end is relative with dead bolt (7); One end of keyhole insulation transmission bar (13) posts conducting strip (14) and with fixedly contact device (5) is relative, the other end gos deep into keyhole (11); One end of electromagnet (3) is provided with an armature (8); Described circuit all uses insulating layer (12) to encase.
