The emergent unlocking method of emergent unlocking method of the present invention, especially electronic lock is the lock chamber based on such lockset
Space is to be extremely limited, but increase emergent unlocking device, to not open lock once, does not need a lock and destroys opening, as far as possible
It reduces the loss of consumer and designs, for this purpose, insight of the invention is that
Lock tongue is set, a lock tongue fixed pin is installed in one end of lock tongue, and the other end of lock tongue is provided with stop platform, lock tongue around
Lock tongue fixed pin can rotate, and when the stop platform of lock tongue is in locked position, lock core is locked, and rotating lock tongue leaves stop platform
Locked position is then unlocked when lock core is rotated.As it can be seen that it is rotating manner that the present invention, which controls the lock tongue then unlocked when lock core is rotated,
It works, designs three functions in a single building, one is when design stop platform is in locked position for locking
Deadlock core, second is lock tongue rotation to make stop platform leave locked position, realizes and then unlocks when lock core is rotated, third is
The directly force contact portion that design rotates lock tongue at the middle part of lock tongue, but be not the mode being fixedly connected, i.e., lock tongue exists
Following stress: lock tongue must exist always with the stress of torsional spring, when lock tongue leaves stop platform in the whole process
When locked position, the elastic force of torsional spring is overcome by external force；When the stop platform of lock tongue is in locked position, external force is withdrawn by.
How in extremely limited space above-mentioned function completed, the present invention designs unidirectional rotation movement mechanism, unidirectional to turn
The motion mode of dynamic movement mechanism can greatly reduce space, for this purpose, the present invention devises the structure of ratcheting motion, the spine
The implementation method of wheel movement is:
1) shaft ratchet is set, and shaft ratchet includes ratchet and shaft, and the two is coaxially fixed to form an entirety, in shaft
On fix a lock tongue finger, shaft ratchet is rotated, and the lock tongue finger on this process shaft ratchet lifts lock tongue, and lock tongue occurs
Rotation, makes the stop platform of lock tongue leave locked position, lock core is rotated, and is unlocked；
2) pawl is set, and the ratchet on shaft ratchet is engaged with pawl, and shaft ratchet and pawl form a kind of one-way movement
Mechanism installs ratchet pawl reset spring on pawl, and ratchet pawl reset spring makes ratchet and pawl on shaft ratchet be in meshing state always,
Shaft ratchet can only be rotated to a direction；
The unidirectional rotation movement mechanism principle formed using shaft ratchet and pawl, is reversed to prevent rotation stop axis ratchet and realizes one
Secondary emergent unlocking；Lock tongue can be stirred by the lock tongue finger on shaft ratchet when external force rotating shaft ratchet and realizes that emergency is opened
Lock mesh.
It can be seen that the unidirectional rotation movement mechanism of shaft ratchet of the present invention and pawl composition, effect is to realize once
Emergent unlocking, shaft ratchet directly provide the force effect of lock tongue rotation by lock tongue finger thereon, and lock tongue finger jacks up lock
Tongue makes its rotation, and the stop platform for allowing it to be located at end leaves locked position, so that lock core is unlocked when can be rotated.
In conclusion technical solution of the present invention, is that aforementioned three settings complete goal of the invention of the invention jointly,
An emergent unlocking is realized in extremely limited space.
Anti-rotation 1-shaped open is arranged in the present invention also on shaft ratchet, needs to provide external force rotation stress incision when emergent unlocking
Mouthful, the anti-rotation 1-shaped open of one readily removable lid of setting, readily removable lid one word platform of setting and shaft ratchet cooperates assembly, prevents under normal circumstances
Shaft ratchet is rotated.It can prevent from malfunctioning.After electronic lock is unlocked, lock must reset to put into again by administrator to be made
With having further compensated for adverse effect after emergent unlocking, further prevented being not reused.
When the ratchet on shaft ratchet is engaged with pawl, between the center of rotation of shaft ratchet and the center of rotation of pawl
Distance be set as a, the maximum distance of center of rotation to the field of conjugate action of pawl is b, the center of rotation of shaft ratchet to the field of conjugate action
Maximum distance be c, then a <b+c.This is the more specific processing for implementing structure.
