Description
Technical field
The present invention relates to electric lockset fields, and in particular to a kind of lock core electronic signal transmission device.
Background technique
The innovation of science and technology is that lockset industry is filled with newborn vigor, conventional lock with people's levels of substance promotion
Continuous growth with for safe and secret aspect demand, is no longer satisfied higher requirement, this just needs to pass through height
The various characteristics of new technology recreate conventional lock, so that improved lockset be made to be able on safety protection function and purposes
Extend and extends.Electric lockset has become indispensable component part in the higher security system of security classification instantly, ground
Position and effect are that tradition machinery lockset can not replace.Common electric lockset will be set to the intracorporal lock core of lock and shift fork separation
Realize that the connection of lock core and shift fork and shaft coupling rotate by hitch bar afterwards, in the feelings that hitch bar does not connect lock core with shift fork
Under condition, after key is inserted into lock core, lock core can only be made to rotate, but shift fork can not be made to rotate, and the rotation of shift fork controls lockset
Unlatching and locking, therefore without corresponding key in the case where started with by traditional mechanical structure, can not open this kind of lock
Have.The sender unit for being allowed to work for starting hitch bar is equipped in key, after key is inserted into lock core, by shaft coupling
The driving circuit of device sends control signal and realizes the effect for controlling and making the two shaft coupling after hitch bar connects lock core with shift fork.
The circuit connection of sender unit and hitch bar generallys use the realization of electric wire connection type, setting and hitch bar in lock core
Driving circuit connection terminals or conductive contact, key be inserted into lock core after, just connect with the terminals or contact, from
And constitute the galvanic circle between sender unit and the driving circuit of hitch bar.It is that can not send out if key mismatches
It send and controls signal correctly to realize the function of driving hitch bar to operate, also just cannot achieve the effect of lockset unlatching.And
It is all more narrow to lock intracorporal Spatial General 6 R, lock core, shift fork and rotation axis must be rotated again at work, therefore electric wire is not
It is only difficult to be arranged in this narrow space, is also relatively easy to generate mill in the rotary course of lock core, shift fork and rotation axis
Poor contact or short circuit, or even fracture is caused to directly result in lockset failure after damage, these weakness of wire connecting fabric are these
The main reason for class lockset service life is short.
Summary of the invention
The object of the present invention is to provide a kind of lock core electronic signal transmission devices, solve the above technical problem.
Technical problem solved by the invention can be realized using following technical scheme:
Lock core electronic signal transmission device, including key and lock body, lock body is interior to be equipped with lock core, shift fork and rotation axis, lock
