Abstract

Electronic anti-theft chain lock, global shape is for example spherical including lock body, locking bar, lock core, end cap, it is characterized by also including electronic anti-theft components, the electronic anti-theft component includes sender unit, signal receiving device, the sender unit is embedded in the locking bar inner end, the lock body bottom has the Hatch Opening for signal receiving device embedment, the signal receiving device is located at below the sender unit, and combined at the top of the signal receiving device with the end cap, it is connected by lock body with the screw hole on end cap to fix.The utility model has the beneficial effects that: for example spherical anti-power unlocking effect of global shape is more；For lock body by including lock core, locking bar, electronic building brick protection, safety coefficient is high, is not easy to be destroyed；The signal strength of the sender unit on lock core is detected by electronic building brick, to judge alarm setting is disassembled and carried out to lock pin whether by violence, error resilience performance is good；Using modular electronic building brick, easy to repair and replacement.

Description

Electronic anti-theft chain lock

Technical field

The utility model relates to a kind of locks, especially electronic anti-theft chain lock.

Background technique

Existing lock is dazzling in the market, such as shackle lock, Steel wire rope lock, joint lock etc., mostly uses purely mechanic lock greatly Key structure realizes locking and unlatching, and configuration aspects are not safe enough, and such lock is rare has electronic warning function, at nobody It easily takes violence to pry open from outside by criminal in the environment kept an eye on, user can neither be reminded in time, can not threaten not Method molecule, anti-theft are relatively poor.

Especially existing chain lock, does not have warning function.

Utility model content

The utility model provides a kind of electronic anti-theft chain lock, ties to overcome above-mentioned prior art shortcoming Structure is succinct, firm and have warning function.

Specifically, the utility model uses the following technical solution:

Electronic anti-theft chain lock, global shape is for example spherical including lock body, locking bar, lock core, end cap, it is characterized by also including Electronic anti-theft component, the electronic anti-theft component include sender unit, signal receiving device, in the sender unit Embedded in the locking bar inner end, the lock body bottom has the Hatch Opening for signal receiving device embedment, and the signal receives dress It is combined below the sender unit, and at the top of the signal receiving device with the end cap, passes through lock body It is connected with the screw hole on end cap to fix.The signal receiving device is removable to be set in lock body, for detecting signal transmitting dress The signal strength set.

Further, the lock core is set in the middle part of lock body, and the head of the locking bar has annular groove, the circle of the lock core Locking bar is limited in the lock body by column position by the annular groove, and locking bar cylinder position, which is additionally provided with, releases locking bar limit The semi-circular slot position of position.When lock gall is opened, latch arm hole is faced with the half slot on movable lock core, this hour locking lever can be free Disengaging, the half slot when locking bar insertion latch arm hole lock gall locks on lock core facing away from the latch arm hole on lock body, this hour locking lever is It cannot extract.

Further, the head of the locking bar is cylindrical body, and the section of the annular groove is trapezoidal shape.

Further, locking bar uses high strength carbon steel material.

Further, the sender unit is magnet.

Compared with prior art, the utility model has the beneficial effects that: for example spherical anti-violence unlocking effect of global shape More；For lock body by including lock core, locking bar, electronic building brick protection, safety coefficient is high, is not easy to be destroyed；It is detected by electronic building brick The signal strength of sender unit on lock core, to judge whether lock pin is disassembled by violence and carry out alarm setting, fault-tolerance It can be good；Using modular electronic building brick, easy to repair and replacement.

Specific embodiment

As shown in Fig. 1 to Fig. 5, the electronic anti-theft chain lock of the utility model includes lock body 1, locking bar 2, end cap 3, lock core 6, envelope Block 10, electronic building brick 21；Locking bar 2 is inserted into lock body 1, with key rotation lock core 6；The head of locking bar 2 has annular groove 67；Lock core 6 envelope blocks 10 are set to 1 middle part of lock body, and envelope block 10 has keyhole；6 bottom of lock core connect with envelope block 10 and can be with key turns；Lock core 6 On be additionally provided with sender unit 61；Electronic building brick is removable to be set in lock body 1, and detection signal transmitting is equipped in electronic building brick 21 The signal receiving device of the signal strength of device.

After being unlocked by key rotation lock core, lock core upper groove 57 faces the latch arm hole on lock body, this hour locking lever It can free in and out in lockhole；When locking bar is inserted into lockhole, and the back of groove 57 after being shut by key rotation lock core, on lock core To the latch arm hole on lock body, this hour locking lever cannot be extracted in lockhole.

Since lock core 6 is equipped with sender unit 61, the signal that detection sender unit is equipped in electronic building brick is strong The signal receiving device 68 of degree.Therefore, in normal unlock, lock core band signal emitter 61 rotates in the normal range, electricity Sub-component detection 68 signal strength of sender unit changes in the normal range；When violence is unlocked, lock gall band movable lock core is remote Super normal range (NR) rotation, electronic building brick detection sender unit signal strength change outside normal range (NR), excite alarm with this.
