Description
Technical field
This utility model belongs to field of lockset, is specifically related to a kind of idle type external source lock core.
Background technology
Traditional mechanical lock has been passed by last 100 years history, its function and performance almost oneself annotate arrived ultimate attainment.But,
Still can not meet modern people to lockset high reliability, high security, informationization, intelligentized requirement, from the end of the fifties, partly lead
After body (transistor) technology is come out, this technology is just applied on lockset by people, and utility model is varied, feature richness
Electric lockset, but there are following problem:
One, the most almost all of electronic lock is all active at present, i.e. must be with power supply electricity inside electric lockset
Source.Active lockset can consume a large amount of battery, need to often safeguard, structure complexity, generalization, standardization level are low, and outside power-off will
Cannot open the door.
Two and (without power supply inside electronic lock cylinder, external active key supply in the most existing passive locks
Electricity, also become external source lock core), almost all of " passive electronic lock " all without lost motion functionality, without the passive locks of lost motion functionality
Because there being impetus, can open with violence brill or violence is turned on, so safety coefficient for passive locks will weaken significantly.
Traditional active electronic lockset either uses electric magnet or the motor can as the driving means of craspedodrome mechanism
Consumption is very big, thus causes electric lockset to be all placed in by power supply in lock, and this is unavoidable selection in fact.Just because of connecting
Power supply, greatly limit the application scenario of electric lockset, cannot connect the remote outdoor locations of external power source for some, and
The industrial occasions of bad environments is all the more so, when active electronic lockset generation power-off then cipher protection function will lose efficacy, and electronics
Unlocking function as power-off and lose function;Also the entrance of opening the door in the event of a power failure such as some communication machine room switchgear houses are given
Maintenance brings puzzlement." passive electronic lockset " is a new important branch in electric lockset field, it and active electronic
The maximum difference of lockset is: utility model person have employed the theory of reverse thinking, necessary for electric lockset working power is moved
Having put on electron key (referred to as: active electronic key), thus, thoroughly solving in traditional active electronic lockset one is
Arrange an intrinsic difficult problem.
Although some documents disclose the technology of passive electronic lock core, but these lock cores are all without lost motion functionality.For
Using metal tools (such as flat mouth screwdriver), external source lock core is turned in violence does not also have effective method, so for passive
The safety of electric lockset (external source lock core) will be had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art to exist, it is provided that during a kind of code error, Lock cylinder idling
's;Match correct active key, just can open;Energy consumption is low, and Prying-resistant and drilling-resistant is prevented cutting what anti-violence was opened;Add idle running merit
Can, the idle type external source lock core that safety is high.
This utility model solves its technical problem and be the technical scheme is that a kind of idle type external source lock core, and it includes
Lock gall, is provided with plectrum in the middle part of lock gall, plectrum has in polygonal first through hole, fit through and be provided with connection in the first through hole
Bar, the two ends of connecting rod are located in inside the through hole of lock gall, and the front end engagement sleeves of connecting rod is provided with lock core protecgulum, in lock core protecgulum
Side is provided with groove hole, and in groove hole, spline is provided with multiple arcuate groove;After through hole one end of lock gall is rotatably connected to lock core
Lid, the outside of lock core bonnet is provided with the cooperation mouth for coordinating active key, the inner side of lock core bonnet be fixed with driving means and
Axle sleeve, the power input of driving means fixes and is electrically connected with chip board, and chip board is electrically connected with active key by electrode,
Being provided with cam on the output shaft of driving means, on cam, hoop has been uniform staggered with two the first grooves and two the second grooves,
The central axis of each groove be arranged in parallel with the axis of cam;Torsionspring, torsionspring it is provided with between cam and driving means
Two ends be respectively canned paragraph and twist section, driving means is fixed with banking stop, banking stop is positioned in second groove, Gu
The section of determining is fixed on banking stop, and twist section is located in another second groove;Cam coaxial is located in axle sleeve, and axle sleeve is with being located in
In groove hole, the diametrically opposite of axle sleeve is provided with two stopper slots, is equipped with rolling element in each stopper slot, and stopper slot is used for limiting
Determine rolling element to move between the first groove and arcuate groove.
First being inserted by active key coordinates in mouth, and active key powers, then to external source lock core of the present utility model
Active key is by electrode and chip board communication, and in the case of password is correct, driving means energising drives cam rotation, by cam
Drive two rolling elements to be pushed into convex position from recess, at this moment rolling element some be in the outside of axle sleeve, and then roll unit
Part blocks the string pendulum position of arcuate groove, at this moment turns active key and plectrum can be driven to open the door, when pulling out key, and driving in lock core
Dynamic device power-off, is returned in situ by torsionspring band moving cam, and rolling element turns again to recess.Now, lock core is in idle running
State, in the case of password bad, or uses external force when turning lock core, and driving means does not perform any action, lock core without
Impetus, it is impossible to band movable lock core protecgulum action, now lock core is in idling conditions, it is impossible to drive plectrum to open the door.
Additionally, lock core shell is negative pole, chip board position positive pole, it is program control that this utility model can realize two-wire by chip board
System.The stress relation of rolling element and cam, it is ensured that the ruggedness of the output shaft of driving means,
The feature of idle running passive electronic lock core of the present utility model is: if stranger inserts thing and attempts to open door lock
Words, passive null rotation cores only can dally, and will not open, it is necessary to matches correct Electronics Cryptographic Keys, and electronic lock cylinder could carry
Lock opened by dynamic interlock, and energy consumption is low, pick-proof, anti-drilling, prevents cutting, and anti-violence is opened.This utility model because of add lost motion functionality,
So security performance improves a lot, it is to avoid outside violence is unblanked, and technology unlocking, owing to lock core is supplied by external electrical key
