Foldable bed frame structure

Abstract

A foldable bed frame structure includes a bed frame, legs, and supports. The bed frame includes a left bed frame and a right bed frame. The legs include a left leg, a right leg, and a middle leg disposed between the left leg and the right leg. The left bed frame and the right bed frame are hingedly connected through connecting members. The middle leg includes a reinforcement transverse pole and a support leg. Two ends of the reinforcement transverse pole are provided with the connecting members, respectively. Longitudinal boards of the connecting members are disposed at inner sides of the left bed frame and the right bed frame. The support leg is disposed between the longitudinal boards of the connecting members. The present invention is safe for use.

I claim: 
     
         1 . A foldable bed frame structure, comprising a bed frame, legs connected to a bottom of the bed frame, and supports connected between the bed frame and the legs, the bed frame comprising a left bed frame and a right bed frame, the legs comprising a left leg, a right leg, and a middle leg disposed between the left leg and the right leg, the left bed frame and the right bed frame being hingedly connected through connecting members, the connecting members each comprising a transverse board for supporting and limiting the left bed frame and the right bed frame and a longitudinal board for connecting the left bed frame and the right bed frame, the longitudinal board having a left hinge hole and a right hinge hole, the left bed frame and the right bed frame being connected with the left hinge hole and the right hinge hole through locking members respectively, characterized by: the middle leg comprising a reinforcement transverse pole and a support leg connected to a bottom of the reinforcement transverse pole, two ends of the reinforcement transverse pole being provided with the connecting members respectively, the longitudinal boards of the connecting members being disposed at inner sides of the left bed frame and the right bed frame, the support leg being disposed between the longitudinal boards of the connecting members. 
     
     
         2 . The foldable bed frame structure as claimed in  claim 1 , wherein the transverse board is integrally formed with the longitudinal board, the longitudinal boards of the connecting members being welded to the two ends of the reinforcement transverse pole, respectively. 
     
     
         3 . The foldable bed frame structure as claimed in  claim 1 , wherein the locking members are screws each comprising a bolt portion and a threaded portion, the bolt portion being located at an inner side of the bed frame, one end of the threaded portion being fixedly connected to the bolt portion, another end of the threaded portion being located inside the bed frame. 
     
     
         4 . The foldable bed frame structure as claimed in  claim 3 , wherein both the left bed frame and the right bed frame are composed of a plurality of pipes, inner ends of the left bed frame and the right bed frame being defined as pipe orifice portions of the pipes, the pipe orifice portions each being provided with a solid block, the threaded portion being screwed to the block.
