Abstract
The invention relates to a lock with a function of reminding that a key is not pulled out, and belongs to the technical field of mechanical locks. The lock comprises a lock cylinder, and a keyhole with an outing opening is formed inside the lock cylinder. The lock is characterized in that an infrared emitter and a light receptor are mounted on two sides of the key hole in the lock cylinder correspondingly, and the light receptor is connected with a warning device through a delay relay. Compared with the prior art, the lock has the advantages of simple structure, high reliability, durability in use and the like, any change to a mechanical drive portion of the lock is not needed, implementation is facilitated, batch production is suitable, and cost can be further lowered by the aid of a power source and a doorbell of an existing antitheft door.
Description
Technical field
The present invention relates to mechanical lockset, be specifically related to a kind of not lock of extraction function of prompting key that has.
Background technology
As everyone knows, lockset is the anti-theft tool of normal use during people live.At present lockset roughly is divided into two large classes: mechanical type and electronic type, although the electronic type lockset has the incomparable high security energy of mechanical lockset, and cost reason thus, mechanical lockset still is main flow.Mechanical lock comprises that mainly lock core and key consist of, in any case and this type of lockset is improved the structure of its lock core key and is improved its theftproof performance, but it is that it can't overcome and solve that a kind of event is arranged: if after in use key being inserted lockhole and opening tapered end, with the key forgetting lockhole, this moment, key can be by anyone taking-up of process, therefore may cause any property loss and even personal safety is on the hazard, need at least to change lock relevant on the key chain.Tracing it to its cause, is that conventional mechanical lockset does not possess prompt facility.
Publication number is disclosed a kind of lock with warning device in the Chinese patent of CN01244467.7, this patent is by in the lockhole of lockset contact switch being set, this contact switch and power supply, the time-delay relay integrated circuit of delay function (or with), pronunciation loudspeaker or doorbell are concatenated into prompting device circuit, key touches the contact switch closure in lockhole, if in time take key away, contact switch then disconnects, if in time do not take key away, then time-delay relay adhesive work after several seconds that arrange, conducting pronunciation loudspeaker send prompt tone, finish the caution process.But this technical scheme is to remove to touch contact switch by the top of key, the phenomenon less than the contact often occurs touching in actual implementation process, thereby can not send alarming sound, and reliability ratio is relatively poor.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of not lock of extraction function of prompting key that has is provided, this lock is by arranging infrared sensing switch in lock core, and this infrared sensing switch connected warn device by time-delay relay, simple in structure, reliability is high, enforcement is convenient.
In order to reach the foregoing invention purpose, the embodiment of the invention proposes a kind ofly has a not lock of extraction function of prompting key.Be achieved through the following technical solutions:
A kind of have a prompting key lock of extraction function not, comprise lock core, described lock core inside is provided with a keyhole with the opening of going out, it is characterized in that: in described keyhole both sides correspondence infrared transmitter and light-receiving device are installed in the described lock core, described light-receiving device is connected with warn device by time-delay relay.
Further preferably, described warn device is buzzer.
Further preferably, described warn device is doorbell.
Further preferably, described warn device is warning lamp.
Compared with prior art, the embodiment of the invention proposes a kind ofly has a not lock of extraction function of prompting key, have simple in structure, reliability is high, the characteristics such as durable in use, the lockset mechanical driving part be need not to do any change, implement easily, be adapted to batch production, and can utilize power supply, the doorbell of existing security door, further reduced cost.
Description of drawings
By the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the present invention will become apparent and understand easily.
To be that the embodiment of the invention is a kind of have a prompting key lock construction schematic diagram of extraction function not to Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail, so that technician's of the same trade understanding:
As shown in Figure 1, label represents respectively: lock core 1, key 2, infrared transmitter 3, light-receiving device 4, time-delay relay 5, doorbell 6, power supply 7.
As shown in Figure 1, has the not structural representation of the lock of extraction function of prompting key for the embodiment of the invention is a kind of.This lock 1 comprises lock core 1 and key 2, and described lock core 1 inside is provided with a keyhole with the opening of going out, and keyhole defines the border of key 2 plugs.In the both sides of described keyhole correspondence infrared transmitter 3 and light-receiving device 4 are installed in the lock core 1.Infrared transmitter 3 is by power supply 7 power supplies and preserve normally open.Light-receiving device 4 is connected with time-delay relay 5, doorbell 6 and power supply 7 both positive and negative polarities and is consisted of a loop.
In use, key 2 inserts in the keyhole of lock core 1, the infrared light beam that blocking infrared transmitter 3 sends, and closed circuit when light-receiving device 4 does not receive infrared light beam, this moment, time-delay relay 5 was in the state of startup.If the user extracts key (after 20 seconds) after opening door lock within normal time, then light-receiving device 4 disconnecting circuits are not worked; If the user is lost in key in the keyhole after unblanking, time-delay relay 5 adhesive work after 20 seconds, conducting doorbell 6 sends caution, and reminding user is extracted key.
Compared with prior art, the embodiment of the invention proposes a kind ofly has a not lock of extraction function of prompting key, have simple in structure, reliability is high, the characteristics such as durable in use, the lockset mechanical driving part be need not to do any change, implement easily, be adapted to batch production, and can utilize power supply, the doorbell of existing security door, further reduced cost.
One of ordinary skill in the art of the present invention are appreciated that; the above embodiment of the present invention only is one of the preferred embodiments of the present invention; be the length restriction; here can not all embodiments of particularize; any enforcement that can embody claim technical scheme of the present invention is all in protection scope of the present invention.
It should be noted that; above content is the further description of the present invention being done in conjunction with concrete embodiment; can not assert that the specific embodiment of the present invention only limits to this; under the guidance of above-described embodiment; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment; as select doorbell as warn device; its purpose mainly is to utilize the doorbell of existing security door; reduce cost; when being applied in the door that does not have doorbell; also can adopt buzzer; warning lamp or utilize the existing equipment that other can play suggesting effect as warn device, and these improvement or distortion drop in protection scope of the present invention.
