Tie-rod luggage box

A tie-rod luggage box comprising:

• a main box body, comprising of a front shell plate and a rear shell plate in open or close state;
• an L-shaped extensible tie-rod, set between the front and rear shell plates, adjacent to one flange of the front and rear shell plates;
• said L-shaped extensible tie-rod at least comprises of a vertical extensible rod set extended vertically along the inner side of the main box body and a transverse handle set at top of the vertical extensible rod set;
• with use of the vertical extensible rod set, the transverse handle could be pulled upwards for holding or pressed downwards into a retractable state;
• a through-type mounting portion in non-recessed state, set between the front and rear shell plates correspondingly to the transverse handle;
• and, said mounting portion could be matched with the transverse handle, such that the transverse handle in idle state could be retracted transversely into the mounting portion;
• since the front and rear shell plates do not require for a recessed portion to accommodate the tie-rod, only a single set of moulds could be used to fabricate the front and rear shell plates of desired integrity, provided that L-shaped extensible tie-rod is set;
• this could save the manufacturing cost, increase the inner space of the main box body and improve its visual effect.
