Description
Technical field
The present invention relates to electric lockset field, and in particular to a kind of lock core electronic signal transmission device.
Background technology
The innovation of science and technology is filled with newborn vigor for lockset industry, and conventional lock is with the lifting of people's levels of substance
Continuous growth with for safe and secret aspect demand, can not meet higher requirement, and this just needs to pass through height
The various characteristics of new technology are recreated to conventional lock, so that the lockset after improving is able on safety protection function and purposes
Extension and extension.Electric lockset turns into indispensable part in the higher safety-protection system of security classification instantly, its ground
Position and effect are that tradition machinery lockset can not substitute.Common electric lockset separates the lock core and shift fork that are arranged in lock body
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 insertion lock core, lock core can only be rotated, but shift fork can not be rotated, and the rotation of shift fork control lockset
Unlatching and locking, therefore without corresponding key in the case of started with by traditional mechanical structure, can not open this kind of lock
Have.It is provided with key and is used to start the sender unit that hitch bar is allowed to work, after key insertion lock core, by shaft coupling
The drive circuit of device sends control signal and realizes that control hitch bar makes the effect of both shaft couplings after lock core is connected with shift fork.
Sender unit connects the realization of generally use electric wire connected mode with the circuit of hitch bar, setting and hitch bar in lock core
Drive circuit connection terminals or conductive contact, key insertion lock core after, just with the terminals or contact portion, from
And constitute the galvanic circle between sender unit and the drive circuit of hitch bar.It is to send out if key mismatches
Correct control signal is sent to realize the function of driving hitch bar running, also can not just realize the effect that lockset is opened.And
Spatial General 6 R in lock body is all more narrow, and lock core, shift fork and rotation axis must be rotated again at work, therefore electric wire is not
Only it is difficult to be arranged in this narrow space, is also relatively easy to produce mill in the rotary course of lock core, shift fork and rotation axis
Loose 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.
The content of the invention
It is an object of the present invention to provide a kind of lock core electronic signal transmission device, solves above technical problem.
