Piece of foldable load-bearing furniture with anti-pinch function

Abstract

A piece of foldable load-bearing furniture with an anti-pinch function includes a load-bearing panel and two X-shaped supporting frames symmetrically arranged on a left side and a right side of the load-bearing panel. Each of the two X-shaped supporting frames includes a front leg and a rear leg which are pivotally connected to each other, and an upper end of the rear leg is pivotally connected to a bottom surface of the load-bearing panel. Upper ends of the front legs are respectively slidably connected to the left side and the right side of the load-bearing panel through a corresponding one of two sliding assemblies and are configured to move forward and backward along the left side and the right side of the load-bearing panel. The upper ends of the front legs extend upward and are connected to each other to form a handle.

         4 . The piece of foldable load-bearing furniture according to  claim 2 , wherein:
 each of the two sliding assemblies comprises a position-stopping block,   the position-stopping block is disposed at a rear end of the sliding rail, and   when the sliding seat slides to correspond to the rear end of the sliding rail, the sliding seat abuts the position-stopping block.   
     
     
         5 . The piece of foldable load-bearing furniture according to  claim 2 , wherein:
 the sliding seat comprises a buckling portion and a pivoting portion located below the buckling portion,   the buckling portion is sleeved on the sliding rail, and   the pivoting portion is pivotally connected to the upper end of the front leg of the corresponding one of the two X-shaped supporting frames.   
     
     
         6 . The piece of foldable load-bearing furniture according to  claim 5 , wherein:
 a width of the upper end of the rear leg in a width direction of the piece of foldable load-bearing furniture gradually decreases from bottom to top, and   when the piece of foldable load-bearing furniture is folded, the pivoting portion is located between the upper end of the front leg and the upper end of the rear leg of the corresponding one of the two X-shaped supporting frames.   
     
     
         7 . The piece of foldable load-bearing furniture according to  claim 4 , wherein:
 a rear side of the load-bearing panel extends upward to form a baffle.   
     
     
         8 . The piece of foldable load-bearing furniture according to  claim 2 , wherein:
 a metal reinforcement tube is provided along a circumferential side of the load-bearing panel.   
     
     
         9 . The piece of foldable load-bearing furniture according to  claim 1 , wherein:
 a distance between the front legs is greater than a width of the load-bearing panel.   
     
     
         10 . The piece of foldable load-bearing furniture according to  claim 1 , wherein:
