Detachable front frame structure and monitor apparatus thereof

A monitor apparatus comprising:

• a monitor;
• and
• a detachable front frame structure accommodating the monitor, the detachable front frame structure comprising:
• a front frame detachably disposed on the monitor and having a first top frame, a first side frame, a first bottom frame, and a first connection frame in sequential connection, the first top frame, the first side frame, and the first bottom frame protruding toward the monitor to form a first outer wall and a first inner wall respectively, and the first top frame and the first bottom frame having at least one shaft respectively to make the first side frame pivotable away from or close to the monitor via the at least one shaft;
• an optical touch module accommodated in the first top frame, the first side frame, the first bottom frame and the first connection frame, for establishing a touch sensing area on the monitor;
• and
• a film component disposed between the front frame and the monitor, the film component comprising:
• a film;
• and
• a film frame having a second top frame, a second side frame, a second bottom frame, and a second connection frame in sequential connection to surround the film, the second connection frame being detachably connected to the first connection frame, the first top frame, the first side frame, and the first bottom frame protruding toward the monitor to respectively form a second outer wall and a second inner wall for defining a limiting slot, and the second outer wall and the second inner wall forming a chamfer structure respectively;
• wherein when the first side frame pivots away from the monitor, the first outer wall of the first top frame and the first outer wall of the first bottom frame slide in the limiting slot, for allowing the film frame to slide into the front frame or be extracted from the front frame;
• when the film frame slides into the front frame and the first side frame pivots toward the monitor, each first outer wall and each first inner wall respectively slide along the corresponding chamfer structure to a position where each first outer wall enters the limiting slot to slide the film frame outward for pulling the film tightly.
