Locking device

A locking device adapted to be used on a claw machine cabinet, the claw machine cabinet including a window frame that defines a mounting space, and a window panel that is mounted in and openably covers the mounting space, the window frame having a receiving chamber that has an open hole, the window panel having a panel portion, and a frame portion that is fixedly connected to the panel portion and that has an engaging slot facing the receiving chamber, the locking device comprising:

• an operating unit that includes
• a cam member adapted to be disposed in the receiving chamber, rotatable around a rotary axis, and having
• a long end that is a first distance away from the rotary axis, and
• a short end that is a second distance away from the rotary axis, the second distance being shorter than the first distance, and
• a locking member connected to said cam member and operable for driving rotation of said cam member;
• and
• an actuating unit that is adjacent to said operating unit, and that includes
• a base plate adapted to be disposed between said cam member and the open hole of the window frame, and abutting against said cam member, and
• a locking rod connected to said base plate, adapted to be aligned with the open hole of the window frame;
• wherein said cam member is rotatable about the rotary axis between a first rotational position, where said long end abuts against said base plate, and a second rotational position, where said short end abuts against said base plate;
• wherein, when said cam member is rotated to the first rotational position, said base plate is pushed to move said locking rod to a locked position, where said locking rod is adapted to protrude outwardly of the open hole and to engage the engaging slot of the frame portion of the window panel;
• and
• wherein, when said cam member is rotated to the second rotational position, said base plate is released to move said locking rod to an unlocked position, where said locking rod is adapted to be disengaged from the engaging slot.
