Abstract
A padlock includes a housing, a shackle having a pivoting portion pivotally passing through a first top hole of the housing into an accommodation chamber of the housing and a locking end passing through a second top hole of the housing, a retaining device disposed in the accommodation chamber and having at least two driving wheels for controlling an axial movement of the pivoting portion of the shackle, and at least two pointers located above a dial of the housing and respectively driven by the driving wheels to point to one of figures of the dial. When both of the pointers point to correct figures, the pivoting portion of the shackle is axially moveable relative to the housing under the control of the driving wheels, such that locking end of the shackle is moveable away from the second top hole of the housing to unlock the padlock.
Claims19
A padlock comprising:
- a housing having an accommodation chamber, a first top hole in communication with the accommodation chamber, a second top hole in communication with the accommodation chamber, and a dial on a top side thereof, which is provided with a plurality of figures;
- a shackle having a pivoting portion pivotally passing through the first top hole of the housing into the accommodation chamber of the housing and axially movable relative to the housing, and a locking end insertable into the second top hole of the housing;
- a retaining device disposed in the accommodation chamber of the housing and having at least two driving wheels for controlling an axial movement of the pivoting portion of the shackle;
- and
- at least two pointers located above the dial of the housing and respectively driven by the driving wheels of the retaining device to point to one of the figures, whereby when both of the pointers point to correct figures, the pivoting portion of the shackle is axially moveable relative to the housing under the control of the driving wheels of the retaining device, such that the locking end of the shackle is movable away from the second top hole of the housing, thereby unlocking the padlock.
A padlock comprising:
- a housing having an accommodation chamber, a first top hole in communication with the accommodation chamber, a second top hole in communication with the accommodation chamber, and a dial with figures;
- a shackle having a pivoting portion pivotally passing through the first top hole of the housing into the accommodation chamber of the housing and axially movable relative to the housing, and a locking end insertable into the second top hole of the housing;
- a latch movably mounted in the accommodation chamber of the housing and provided with at least two insertion portions;
- a block member connected to the latch and drivable by the latch to move relative to the pivoting portion of the shackle,
- at least two driving wheels respectively and rotatably mounted in the accommodation chamber of the housing;
- at least two transmission wheels coaxially arranged in the accommodation chamber of the housing and engaged with the driving wheels respectively;
- at least two pointers located above the dial and coupled to the transmission wheels respectively such that the pointers are drivable by the driving wheels through the transmission wheels to rotationally move for pointing one of the figures, and
- at least two retaining wheels each having a notch and respectively coaxially connected with the transmission wheels in such a way that the retaining wheels are rotatable along with the transmission wheels respectively, and when both of the pointers are respectively point to correct figures, the insertion portions of the latch are inserted into the notches of the retaining wheels such that the block member is driven by the latch to move away from the pivoting portion of shackle, resulting in that the pivoting portion of the shackle is axially movable relative to the housing and the locking end of the shackle is movable away from the second top hole of the housing to unlock the padlock, and when one of the pointers points to an incorrect figure, the insertion portions of the latch are departed from the notches of the retaining wheels such that the block member is driven by the latch to block the pivoting portion of the shackle, resulting in that the pivoting portion is axially immovable relative to the housing.
