Steel-wood composite board and filing cabinet made thereof

Abstract

A steel-wood composite board and a filing cabinet using the same are disclosed. The steel-wood composite board includes a steel frame and a wooden lining plate inlaid in the steel frame. The steel frame includes reinforcing pillars closely fitting the lining plate. The reinforcing pillar is fixedly connected to the lining plate and the steel frame. By using the steel-framed wood boards, the filing cabinet not only significantly reduces costs for both material and transportation, reduces the overall weight of the resulting product, and increases the overall robustness of the resulting product, but also simplifies production, reduces manufacturing costs, and eliminates the risk of board deformation during transportation. The wood board and the steel frame of the lateral plate are factory-assembled, thereby saving users from the troublesome assembling process and significantly improving user experience.

What is claimed is: 
     
         1 . A steel-wood composite board, comprising a steel frame and a lining plate, wherein the lining plate is a wood board inlaid in the steel frame, and the steel frame comprises reinforcing pillars that closely fit the lining plate and are fixedly connected to the lining plate and the steel frame, respectively. 
     
     
         2 . The steel-wood composite board of  claim 1 , wherein the reinforcing pillar is one or more of a cross bar, a post, an inclined rod, and an arched bar. 
     
     
         3 . The steel-wood composite board of  claim 1 , wherein the lining plate has a thickness of between 2 mm and 5 mm. 
     
     
         4 . The steel-wood composite board of  claim 1 , wherein the lining plate has a thickness of 3 mm. 
     
     
         5 . A filing cabinet, comprising the steel-wood composite board of  claim 1 . 
     
     
         6 . The filing cabinet of  claim 5 , further comprising a top plate, lateral plates, a back plate, a bottom connecting member, and a drawer, wherein each of the lateral plates is made of the steel-wood composite board, two sides of the top plate being fixed to steel frames of the two lateral plates, respectively, two sides of the back plate being fixed to the steel frames of the two lateral plates, respectively, two lateral slides of the drawer being fixed to the steel frames of the two lateral plates, respectively, and two ends of the bottom connecting member being fixed to the steel frames of the two lateral plates, respectively. 
     
     
         7 . The filing cabinet of  claim 6 , wherein each of the steel frames is provided with a threaded hole for a screw to pass through so that the top plate and/or the back plate and/or the bottom connecting member are connected to the steel frame by the screw. 
     
     
         8 . The filing cabinet of  claim 6 , wherein each of the steel frames is provided with a fastening tongue and the fastening tongue is provided with a threaded hole for a screw to pass through so that the top plate and/or the back plate and/or the bottom connecting member are connected to the fastening tongue by the screw. 
     
     
         9 . The filing cabinet of  claim 6 , further comprising a plurality steel rods, wherein the steel rods and the steel frames are all provided with threaded holes for screws to pass through so that the top plate and/or the back plate and/or the bottom connecting member are connected to the steel rods by the screws, and the steel rods connects the two steel frames together through the screws. 
     
     
         10 . The filing cabinet of  claim 6 , wherein the steel frame has a bottom provided with a base, and the base comprises casters or wood legs or steel legs.
