Abstract

An induction type padlock includes a shell, a lock bolt, a shackle, a driving unit, a light-emitting component, and an induction control unit. The lock bolt slides in the shell and has a recess. The shackle is inserted into the shell through the lock bolt and has a latch portion being able to be latched by the lock bolt. The driving unit rotates the position limiter in the recess; the position limiter has a wide portion and a narrow portion. The induction control unit is electrically connected to the driving unit and the light-emitting component. The induction control unit senses a signal to select the wide or the narrow portion of the position limiter to be disposed in the recess and controls the light-emitting component. Therefore, the time delay problems of unlocking and locking can be solved and the distinguishable lighting indications of unlocking and locking can be obtained.

Claims

1. An induction type padlock, which is used to sense a signal to be actuated, comprising:

a shell;

a lock bolt sliding in the shell and provided with a recess, wherein the lock bolt is provided with at least one latch member;

a shackle inserted into the shell through the lock bolt, wherein the shackle is provided with at least one latch portion latched by the latch member correspondingly;

a driving unit disposed in the shell to rotate a position limiter disposed in the recess, wherein the position limiter has at least one wide portion corresponding to the width of the recess and at least one narrow portion shorter than the width of the recess;

a light-emitting component disposed in the shell and emitting light outward thorough the shell; and

an induction control unit disposed in the shell and electrically connected to the driving unit and the light-emitting component, wherein the induction control unit senses the signal to control the driving unit to drive the position limiter to select the wide portion or the narrow portion to be disposed in the recess without moving the lock bolt and controls the lighting of the light-emitting component.

2. The induction type padlock according to claim 1, further comprising a power supply disposed in the shell and electrically connected to the induction control unit.

3. The induction type padlock according to claim 1, wherein the shell is provided with a groove in which the lock bolt slides, wherein the lock bolt has a press portion protruding out of the groove.

4. The induction type padlock according to claim 3, wherein the press portion is formed at one end of the lock bolt, wherein a first elastic part is flexibly supported between another end of the lock bolt and an inner wall of the groove.

5. The induction type padlock according to claim 3, wherein the shell is provided with two insertion holes spaced from each other, wherein each of the two insertion holes penetrates through and communicates with the groove, wherein the shackle has two insertion portions which individually insert into the insertion holes correspondingly.

6. The induction type padlock according to claim 5, wherein the number of the latch members and the number of the latch portions are both two, wherein the lock bolt is provided with two throughholes which individually correspond to the insertion holes in which the latch members are individually disposed, wherein each of the insertion portions of the shackle has the latch portion, wherein the latch members of the lock bolt individually latch the latch portions of the shackle correspondingly.

7. The induction type padlock according to claim 5, wherein a stop flange is disposed in the shell corresponding to one of the insertion holes, wherein one of the insertion portions of the shackle is provided with a stop portion corresponding to and stopping the stop flange.

8. The induction type padlock according to claim 1, wherein the induction control unit has a switch disposed on an insertion path formed by the shackle inserting into the shell such that a control signal is generated after the shackle is inserted to actuate the switch, wherein the induction control unit controls the driving unit to rotate the position limiter reversely according to the control signal.

9. The induction type padlock according to claim 8, wherein the shell further comprises a guide groove and a flexible part sliding corresponding to the guide groove, wherein two ends of the flexible part individually press against the switch and one end of the shackle.

10. The induction type padlock according to claim 9, wherein the flexile part comprises a second elastic part and two support parts which individually contacts two ends of the second elastic part, wherein the guide groove has two open ends from which the two support parts individually protrude.

11. The induction type padlock according to claim 1, wherein the at least one wide portion of the position limiter is formed as a pair of wide portions and the at least one narrow portion of the position limiter is formed as a pair of narrow portions, wherein the pairs of the wide portions and the narrow portions are alternately connected to each other.
