Description
Technical field
The utility model relates to a kind of auxiliary mechanical unlocking mechanisms of electronic lock.
Background technique
Currently used door electronic lock, including card lock, coded lock, Fingerprint Lock etc., door-opening mechanism are all to verify
By rear, by controller driving motor, and then clutch driven to combine, turned the handle at this time, the rotation of driving gate handle axle,
So that lock tongue is withdrawn, such door can be opened.Although the door-opening mechanism terminal section of i.e. electronic lock is also to have mechanical action,
It is very big with traditional mechanical lock difference.The door-opening mechanism of electronic lock can be understood as directly opening certain switch, so that door can be with
It opens；And mechanical lock then needs the cooperation of key and lockhole, so that lock core can rotate, so as to open door.In this way
Architectural difference make electronic lock when out of power, often also stopping acts the door-opening mechanism of its electronic lock, i.e. electronic recognition
When part or clutch motor drive part do not have power supply, the door-opening mechanism mechanism of electronic lock can not be manipulated；So in order to pacify
For the sake of complete, electronic lock requires while installing mechanical unlocking device, in this way in situation out of power other than electronics unlocking mechanism
Under, door can be opened by mechanical key, this ensure that safety, and avoid carrying out forcible entry unlocking when power shortage, cause economy
Loss.The spare unlocking system of machinery of electronic lock is typically direct-connected, it can has regarded that parallel connection one is commonly locked into electricity as
Sub- lock system, lockhole mechanical in this way are perpendicular to a direction outside, and such lockhole is exposed entirely uncoordinated with electronic lock, so through
Often add a lid outside lockhole, and this direct-connected mechanical lock also limits the arrangement space of electronics lock assembly.
Summary of the invention
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of concealed machinery of electronic lock is provided
Unlocking mechanism is achieved through the following technical solutions:
A kind of concealed mechanical unlocking mechanism of electronic lock, the mechanism include that back box, lock core, lock core connecting rod, one end are
The helical teeth connecting rod of helical teeth, be on one side helical teeth another side be the compound gear of coaxial straight-tooth, center be equipped with circular groove straight-tooth gear, pin
Axis and cover equipped with the pin shaft limit hole；The compound gear, straight-tooth gear are located at the box of the back box and cover composition
In vivo, the lock core is mounted in the front panel of electronic lock, and downward, the lock core other end hinge lock core connects the lock core lockhole
Bar, the lock core connecting rod are coaxially connected with helical teeth connecting rod, and the helical teeth of the helical teeth connecting rod is located in the box body；The helical teeth connects
90 degree of helical teeth of the helical teeth of bar and compound gear are ratcheting；The straight-tooth of the compound gear and the straight-tooth gear are ratcheting；The pin
The circular groove of one end of axis and straight-tooth gear pass through the fixture block card being correspondingly arranged and, the other end of the pin shaft stretches out the cover
Limit hole.In use, key is inserted into the keyhole of lock core upward, key is rotated, then lock core connecting rod and helical teeth link rotatable, pass through
Vertical rotation axis is transformed into the shaft of horizontal object door by the cooperation of helical teeth, is then driven by compound gear to straight-tooth gear, by
And, avoiding mutually rotating between the two in the fixture block of straight-tooth gear circular groove and the fixture block card of pin shaft end, i.e. drive pin shaft rotates,
The other end of pin shaft gos deep into lock body, movement with it is traditional to be placed in the lock core movement of lock body identical, to realize unlocking.
Further, the back box lower part is equipped with helical teeth connecting rod limiting slot.It can unlock more to avoid the shaking of helical teeth connecting rod
Add stabilization.
Further, the limiting slot is U-shaped, and the limiting slot opening is equipped with limited block.Limited block is plastics or rubber
The bar portion of helical teeth connecting rod is limited between limited block and back box in this way, and plays cushioning effect by blob of viscose.
Further, the lock core is connected with the fixinig plate for being equipped with screw hole.Lock core can be consolidated by fixinig plate in this way
Determine on the front panel, to avoid shaking.
Further, the lock core connecting rod is screwed by screw thread with helical teeth connecting rod and is connect.Such as the head end in lock core connecting rod
If external screw thread, internal screw thread is set in one end of helical teeth connecting rod, the two screws connection.
The utility model has the beneficial effects that the utility model separates lock core and lock body, so that before lock core may be mounted at
Lower panels, lockhole is downward, very hidden, while having risen out space, and coded lock front panel center is allowed to vacate sky
Between other important components are installed.Mechanism structure is simple, and part is few, easy to process, and reliability is high, realizes concealed mechanical
It unlocks, the advanced and especially suitable mechanism of the high electric lockset of added value.
