Containing Box Structure

Abstract

A containing box structure for containing objects includes a lid covered onto a top opening of the containing box, a front cover pivotally installed to the periphery of a side of a front opening, and a space concavely formed on a side of the bottom of each containing box and provided for inserting an auxiliary support member to stably stack plural containing boxes in a quick operation, and a containing area defined in a corresponding section of the lid that covers the top opening of the containing box and provide for stacking the containing boxes on one another, and the auxiliary support member of an upper containing box may be pulled out to latch into the corresponding containing area of the lid that covers a lower containing box to achieve a desired stable position restriction.

What is claimed is: 
     
         1 . A containing box structure, provided for containing objects, comprising: a lid covered onto a top opening of the containing box, a front cover pivotally installed to the periphery of a side of a front opening, a space concavely formed on a predetermined side of the bottom of each containing box to stably and quickly stacking a plurality of containing boxes and provided for inserting an auxiliary support member, and a containing area defined at a corresponding section of the lid that covers the top opening of the containing box; thereby, when the containing boxes are stacked on one another, the auxiliary support member installed at the bottom of an upper containing box is pulled out to latch into the corresponding containing area of a lid of a lower containing box to achieve a desired stable position restriction. 
     
     
         2 . The containing box structure as claimed in  claim 1 , wherein the space for inserting the auxiliary support member into the bottom of the containing box includes a guide portion and a limit protrusion disposed at predetermined positions of the space respectively to limit an end of the auxiliary support member when the auxiliary support member is pulled out to a distance, so as to prevent the auxiliary support member from falling out. 
     
     
         3 . The containing box structure as claimed in  claim 1 , wherein the containing box has one or more rod sections extended outwardly from the periphery of a side of the front opening, and the lower periphery of the front cover is appropriately engaged into an interval concavely and inwardly formed at a corresponding position, such that the front cover and the containing box are maintained to be pivotally coupled to one another as a whole. 
     
     
         4 . The containing box structure as claimed in  claim 1 , wherein the containing box has a truncated projecting portion extended from the lateral periphery pivotally coupled to the front cover and disposed at a position inwardly facing the upper periphery, and the lid is inserted into a corresponding position of the recessed space to define a position restriction when the front cover is lifted. 
     
     
         5 . The containing box structure as claimed in  claim 1 , wherein the containing box has one or more protrusions disposed at predetermined positions of the upper periphery of the front cover with a pivotally coupled lateral periphery and insertable into a recession of a corresponding section of the lid. 
     
     
         6 . The containing box structure as claimed in  claim 1 , wherein the lid covered onto the top opening of the containing box has a plurality of protrusions disposed at predetermined positions inwardly facing the lateral periphery, and the protrusions are inserted into the periphery extended outwardly from the top opening of the containing box, so as to maintain a position restriction between the lid and the containing box.
