FIGS. 6d and 7d has shown a state of the lock of the present embodiment in which the lock is being actuated by the toggle piece 41 to realize double locking. After the user drives the toggle piece 41 upwardly, as the toggle piece 41 is hinged to the face case 11, the toggle block 411 at the other end of the toggle piece 41 pushes the slider 43 in a direction G. The input rack 432 on the slider 43 drives the clutch pinion 513 on the clutch component to rotate in a direction H, and the clutch block 512 pus hes the first transmission block 552 to rotate in the direction H, thereby driving the first receiving portion 92 to rotate and drive the dead bolt 72 to extent outwardly to realize the double locking. Simultaneously, the transmission gear 553 of the dead bolt driving component 55 also drives the driving rack 521 of the unlocking transmission member 52 in a direction F to return to its initial position.
In the embodiment described above, by using the lock cylinder assembly 30 as an unlocking portion and the toggle piece assembly 40 as a driving input portion, the rotation of the unlocking portion is converted into the rotation of the dead bolt driving component 55 in the first direction, and the upward and downward movements of the driving input portion are respectively converted into the rotation of the dead bolt driving component 55 in the second direction and the rotation of the latch bolt driving component 54 in the first direction, which further realizes the double locking and unlocking of the dead bolt of the lock, and the extending outwardly of the latch bolt of the lock.
It can be understood that, in other embodiments not shown, the unlocking portion, the driving input portion, the driving component, the dead bolt driving component, the latch bolt driving component can adopt other forms. For example, the unlocking portion and the driving input portion may be provided as coaxially arranged and relatively rotatable parts, or the dead bolt driving component and the latch bolt driving component may be provided separately from each other and arranged in parallel, instead of being arranged in a coaxial manner. Alternatively, the dead bolt driving component can be mounted around. the radially outer side of the latch bolt driving component, etc. The clutch component and the unlocking transmission member, or one of the clutch component and the unlocking transmission member can also be arranged coaxially or in parallel with the unlocking portion and the driving input portion. That is, the dead bolt driving component, the latch bolt driving component and the clutch component are arranged in the same direction along their respective axial directions, the clutch component and the unlocking transmission member can be respectively driven by the unlocking portion and the driving input portion to rotate in different directions. Alternatively, the transmission between the clutch component and the dead bolt driving component or the clutch component and the latch bolt driving component may be configured in a manner of rack-and-pinion engagement. Further, in addition of using a rack-and-pinion engagement for transmission, a lever type, a bouncing type, a prizing type transmission can also be used between the clutch component and the driving input portion, or between the clutch component and the dead bolt driving component, or between the clutch component and the latch bolt driving component.
