Abstract

The utility model relates to a lock core, a key hole of which is provided with a detecting device, and belongs to the lockset field. The lock core comprises a mechanical lock core unlocked by a key and a detecting device. The detecting device is arranged on the lock core; at least one detection point of the detecting device is arranged in the key hole; a key hole channel is closed, monitored and detected through the detection points of the detecting device so that whether an unlocking tool is inserted in the key hole or not can be detected and a detection signal can be transmitted through conducting wires or a wireless manner. The utility model solves the problem that the lock core in the prior art can not detect the insertion of any unlocking tools into the key hole so that the development of the lockset is limited. After any unlocking tools are inserted in the key hole, the lock core provided the detection device can detect the condition though the detection device and sends the detection signal through the conductive wire or the wireless manner, without impacting on the normal insertion and unlocking of the key. Furthermore, the utility model has the advantages of simple structure, accurate and reliable detection, and suitability for various alarming locksets.

Description

The lock core that has checkout gear

Technical field:

The utility model relates to a kind of lock core that has checkout gear, belongs to field of lockset.

Background technology:

At present, lockset on the market is a lot, various types of locksets have, aspect safety, all be based on the soundness of reinforcement lockset or the anti-technical unlocking ability of lock core, make lockset be difficult to be opened or pried open, but this can only prolong lockset by the time of technical unlocking or the unlatching of destroyed property.Also there is now the keyhole of lockset to be provided with checkout gear, can provide detection signal for the control system of peripheral hardware, but the content of its detection is selective, does not possess when keyhole is inserted into any unlocking tool, and the ability that can detect makes the development of lockset be subjected to considerable restraint.And as development warning lockset, just need especially a kind of when in the lock core keyhole during any unlocking tool of insertion, the lock core that can detect just.

Summary of the invention:

The purpose of this utility model is: a kind of lock core that has checkout gear is provided, the checkout gear of lock core is provided with at least one test point in keyhole, when inserting any unlocking tool in the keyhole, can both detect immediately, and not influence the insertion of key and unblank.

The utility model is to realize above-mentioned purpose by following technical solution:

A kind of lock core that has checkout gear, it is by using key operated mechanical lock and checkout gear to constitute, described mechanical lock comprises lock tube, lock gall and keyhole, it is characterized in that: checkout gear is arranged on the mechanical lock, described checkout gear is a switching device, the test point of checkout gear is arranged in the keyhole, is provided with a test point in the keyhole at least.

Described checkout gear is contact switch, near switch, Hall switch or infrared switch, and whether with form sealing, the monitoring of machinery or electronics with detect the keyhole passage of lock core, detecting keyhole has unlocking tool to insert.When unlocking tool inserts keyhole, can detect immediately, and can provide detection signal for the external world, but not influence the insertion of key and unblank by lead on it or wireless transmission form.

The utility model beneficial effect compared with prior art is:

This has the lock core of checkout gear owing to be provided with test point in keyhole, and by test point sealing, monitoring and detection keyhole passage, when inserting any unlocking tool in the keyhole, checkout gear can both detect immediately by test point, and can provide detection signal for the external world by lead on it or wireless transmission form, and simple in structure, detect accurately and reliably.

Description of drawings:

Fig. 1 is checkout gear by contact switch and detects pellet shot from a slingshot and forms that contact switch is contained on the lock tube, the structural representation of the mortise door lock core by detection pellet shot from a slingshot sealed key hole;

Fig. 2 is that checkout gear is made up of the transmitting terminal and the receiving terminal of infrared switch, the structural representation of the mortise door lock core by the infrared rays sealed key hole.

Among the figure: 1, lock tube, 2, lock gall, 3, shifting block, 4, pellet shot from a slingshot, 5, keyhole, 6 contact switch, 7, detect pellet shot from a slingshot, 8, the infrared switch transmitting terminal, 9, the infrared switch receiving terminal.

The specific embodiment:

Embodiment 1:

This lock core that has checkout gear is by using key operated mechanical lock and checkout gear to constitute.Mechanical lock comprises lock tube 1, lock gall 2, shifting block 3, pellet shot from a slingshot 4 and keyhole 5; Checkout gear constitutes (referring to accompanying drawing 1) by contact switch 6 and detection pellet shot from a slingshot 7.Lock gall 2 is contained in the lock tube 1, and an end of lock gall 2 is connected with shifting block 2, embeds the pellet shot from a slingshot 4 that locking is arranged between lock tube 1 and the lock gall 2, has keyhole 5 in the lock gall 2.The contact switch 6 of checkout gear is contained on the lock tube, and the effect by self spring force makes the passage that detects pellet shot from a slingshot 7 sealings, monitoring and detect keyhole 5, generally with first pellet shot from a slingshot of keyhole 5 inlets as detecting pellet shot from a slingshot 7.

Its operating principle is: when key or other unlocking tool insertion keyhole 5, must pass through test point, promptly detect pellet shot from a slingshot 7 enclosed areas, will inevitably cause and detect the direction motion of pellet shot from a slingshot 7 to contact switch 6, touch contact switch 6 actions, the constant close contact of contact switch 6 inside is disconnected, and the constant open contact closure, this moment, 6 of sense switches were by the lead on it or the form of wireless transmission, detected signal is spread out of, for extraneous control system provides detection signal, showing has key or other unlocking tool to insert in the keyhole 5.

Embodiment 2:

This mechanical lock of lock core that has checkout gear is with embodiment 1, and described checkout gear constitutes (referring to accompanying drawing 2) by infrared switch transmitting terminal 8 and infrared switch receiving terminal 9.Infrared switch transmitting terminal 8 and infrared switch receiving terminal 9 are contained on the lock tube 1, are passed the zone of lock gall 2 between them by a through hole, by the passage of infrared rays sealing, monitoring and detection keyhole 5.

Its operating principle is: when key or other unlocking tool insertion keyhole 5, key must pass through the test point by keyhole 5 zones of infrared

switch transmitting terminal

8 and 9 sealings of infrared switch receiving terminal, the infrared rays of infrared switch is disconnected, and infrared switch is moved, infrared switch is then by the lead on it or the form of wireless transmission, detected signal is spread out of, and for extraneous control system provides detection signal, showing has key or other unlocking tool to insert in the keyhole 5.

Two above-mentioned embodiment only are two kinds of forms of expression of specific embodiment, and the concrete structure and the set-up mode of checkout gear of the present utility model are not limited only to the foregoing description.Along with the difference of lock core structure, checkout gear is provided with the position on lock core, and the structure of the quantity of test point and the checkout gear of employing also can be different.As long as be fit to be installed on the lock core, can seal, monitor and detect the keyhole passage of lock core with the form of machinery or electronics, can when key or other unlocking tool insertion keyhole 5, move, and can be by the form of lead or wireless transmission, for extraneous control system provides the switching component of detection signal, can use as checkout gear.Test point is general only need to be provided with one, also can be provided with a plurality ofly, and when only being provided with one, operated by rotary motion is in the outer end near keyhole 5, and the inner end of keyhole 5 is not advised being arranged in the perhaps centre position of keyhole 5.
