Description
Technical field
The utility model provides finger-print cipher key electricity meter box theftproof lock.
Background technology
Electric energy has to produce with using as a kind of special commodity and carries out simultaneously and do not have a visible characteristic in kind.For making electric energy not cause dead wight loss on intermediate links, power supply department need carried out anti-electricity-theft management work from every side.Energy meter metering electric weight is that therefore, any one that changes in the three elements can make energy meter slow-speed, stall even counter-rotating by voltage, electric current, power factor three elements and the decision of the product of time.Show that according to numerous stealing cases stealing need change above-mentioned electric-power metering three elements, most ways are from changing starting with of metering device, because tool disguise in the weigh box is difficult for being found.
Before the utility model proposes, at power domain various be used to measure power consumption and special-purpose instrument and meter locksets are arranged, this lockset all is common lock or the electronic lock all kinds of ammeters that lock usually.Because common lock pried open easily or open with common key, electronic watch is also given away secrets easily, so do not possess anti-theft feature, is subjected to artificial destruction or misoperation easily and electricity and security incident occur stealing.
Summary of the invention
For a kind of special use lock with anti-theft feature is provided, the utility model provides finger-print cipher key electricity meter box theftproof lock.This lock solves the antitheft technical problem of ammeter lock by finger-print cipher key and the induction lock that USB interface is installed.
The scheme that the utility model technical solution problem is adopted is:
Side at lock body is equipped with USB interface, lock core is installed in lock body, lock core one side is connected with driver, the lock rod is installed in lock core, is provided with pintle hook lock in lock rod one side of lock body, the side relative with USB interface at lock body is connected with receiver, receiver passes to driver with the signal instruction that receives, driver is installed with the armature of lock rod is approaching, is provided with spring stop in the lock rod telescopic cavity of lock core, and spring stop one side is set with spring.
In the finger-print cipher key battery is housed, the battery plus-negative plate lead constitutes the loop with derailing switch and electromagnetic coil respectively, is connected with Fingerprint Identification Unit on derailing switch.
Good effect, the utility model theftproof lock is with the key operated induction lock that is connected with USB interface of finger-print cipher, realized opening or the induction lock that locks according to the key that is set with finger-print cipher, when induction lock breaks down or during the fingerprint key loss, by the USB loader, the input unlocking cipher realizes that no fingerprint key just can open induction lock.Owing to can only just can carry out opening or closing of electricity meter box with Fingerprint Identification Unit or USB loader, so have anti-theft feature.The utility model suits to install and use on all kinds of ammeter housings or electricity meter box.
Description of drawings
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model finger-print cipher Key structure figure
Among the figure, 1. lock body, 2.USB interface, 3. lock core, 3.1. armature, 3.2. spring stop, 3.3. spring, 4. driver, 5. receiver, 6. lock rod, 7. pintle hook lock, 8. finger-print cipher key, 8.1. battery, 8.2. Fingerprint Identification Unit, 8.3. derailing switch, 8.4. electromagnetic coil.
The specific embodiment
According to the figure, side at lock body 1 is equipped with USB interface, lock core 3 is installed in lock body, and lock core one side is connected with driver 4, and lock rod 6 is installed in lock core, lock rod one side at lock body is provided with pintle hook lock 7, be connected with receiver 5 in the lock body side relative with USB interface, receiver passes to driver with the signal instruction that receives, driver and armature 3.1 approaching installations of locking rod, be provided with spring stop 3.2 in the lock rod telescopic cavity of lock core, spring stop one side is set with spring 3.3.
Battery 8.1 is housed in the finger-print cipher key 8, and the battery plus-negative plate lead constitutes the loop with derailing switch 8.3 and electromagnetic coil 8.4 respectively, is connected with Fingerprint Identification Unit 8.2 on derailing switch.
The utility model theftproof lock belongs to electromagnetic induction coded lock type.
The utility model theftproof lock can lock on/off by enough finger-print cipher keys, under the situation that does not have the finger-print cipher key, can realize locking on/off with the finger-print cipher that computer retained by the USB socket that is connected on the lock body.Can also revise finger-print cipher by the computer corresponding software programs, be used for repairing or changing finger-print cipher.
Use of the present utility model
During installation, lock body and pintle hook lock are installed in the both sides of ammeter chamber door respectively.
With finger-print cipher key alignment receiver, receiver received pulse signal is also responded to electromagnetic coil in the driver, and adhesive lock rod overcomes spring force and move in lock core and lock, and the disengaging pintle hook lock at this moment, just can be opened lock body, and open the ammeter chamber door.
Close when locking when the ammeter chamber door, the fingerprint key is taken away from receiver, make it break away from receiver, do not have drive current to act on the lock core, at this moment, the elastic force by spring makes the locking of lock rod in pintle hook lock, has realized the locking of electricity meter box.
Characteristics of the present utility model
1, the finger-print cipher key is to the identification of holder's fingerprint;
2, start password program behind the recognition and verification, lock is operated release;
3, digital deciphering key is realized the deciphering interlock of the password setting and the digital electric key of electronic lock;
4, release memory function, the concrete time of record opening/closing lock;
5, the release number of times of regularly really weighing and limiting is finished the mandate of key and the unified management that record is preserved;
6, the alarm function of the specific lock of opening/closing;
7, the mandate importing of key and operation note are derived and are finished by being connected with the computer terminal, and many station terminals connect by same central server of network;
8, the number of passive locks and active key identification can be changed the password of digital electric release at any time by adding USB interface.
9, the background terminal machine has modify feature to the key fingerprint recognition system.
