Abstract

According to the present invention, a key box is provided to include: a body; a cover, pivotally connected with the body to render an open state and a closed state; and a panel set, embedded on the cover, comprising a keypad module and a lock module. Wherein, by manipulating either the keypad module or the lock module, the open state and the closed state can be switched.

Claims

1. A box, comprising:

a body;

a cover, pivotally connected with the body to render an open state and a closed state;

a panel set, embedded on the cover, comprising a keypad module and a lock module, switching between the open state and the closed state being performed by manipulating either the keypad module or the lock module; and

a switch module provided at an inner side of the cover, the switch module comprises;

a plate;

a first sliding piece, slidably provided on the plate;

a pair of rotating pieces, rotatably provided on the plate; and

an solenoid switch, comprising a blocking section, wherein the blocking section is positioned against the first sliding piece under the closed state and is disengaged from the first sliding piece under the open state.

2. The box as claimed in claim 1, wherein the sliding piece comprises a push piece for coordinating with the keypad module for switching the key box between the open state and the closed state.

3. The box as claimed in claim 2, wherein the panel set is configured with an opening, further comprises:

a pair of substantially parallel guiding tracks, positioned at two sides of the opening; and

a button, accommodated in the opening, being restrained to slide along a predetermined direction according to the pair of guiding tracks.

4. The box as claimed in claim 1, wherein the plate further comprises a positioning piece for positioning the blocking section.

5. The box as claimed in claim 4, wherein the positioning piece comprises non-magnetizing material.

6. The box as claimed in claim 1, further comprising a second sliding piece slidably provided on the first sliding piece.

7. The box as claimed in claim 6, wherein the second sliding piece comprises a push piece for coordinating with the lock module for switching the box between the open state and the closed state.

8. The box as claimed in claim 1, further comprising a concealing cover for movably covering the lock module.

9. The box as claimed in claim 1, further comprising a circuit board near the keypad module, the circuit board being electrically connected with the keypad module and the solenoid switch.
