Description

TECHNICAL FIELD

The present invention relates to a file cabinet, particularly to a combined and upright file cabinet constituted of some plastic composite boards.

BACKGROUND OF THE TECHNOLOGY

File cabinet is widely used at offices, bedchambers and so on because of its practicability. Existing file cabinets are mostly made by wood, which wastes much wood and destroys environment. So wood file cabinets are gradually replaced by plastic file cabinets. Existing plastic file cabinets have disadvantages as follows: firstly, plastic boards can not support great weight; secondly, adopting solid plastic boards will waste materials and have great weight; thirdly, file cabinets are no knock-down connection, which have great cubage, low connection intensity and bad sight.
