Frame structure, stool, and bed

Abstract

A frame structure comprises a first outer frame, a second outer frame, at least two lateral rods, and a lateral rod clamping member. A plurality of connecting members are respectively separably connected to the first outer frame, the at least two lateral rods, and the second outer frame. The first outer frame and the second outer frame each comprise an inner tube, an outer tube, and an adjustment member for adjusting a relative position of the inner tube and the outer tube. Each of the at least two lateral rods comprises an inner rod and an outer rod. The lateral rod clamping member enables part or all of the at least two lateral rods to be connected together.

What is claimed is: 
     
         1 . A frame structure, comprising:
 a first outer frame,   a second outer frame opposite to the first outer frame,   at least two lateral rods disposed between the first outer frame and the second outer frame, and   a lateral rod clamping member, wherein:
 a plurality of connecting members are respectively separably connected to the first outer frame and the at least two lateral rods, two adjacent lateral rods of the at least two lateral rods, and the at least two lateral rods and the second outer frame, 
 the first outer frame and the second outer frame each comprise an inner tube, an outer tube movably connected to the inner tube along a length direction of the first outer frame or the second outer frame, and an adjustment member for adjusting a relative position of the inner tube and the outer tube, 
 each of the at least two lateral rods comprises an inner rod and an outer rod movably connected to the inner rod along a length direction of the at least two lateral rods, and 
 the lateral rod clamping member enables part or all of the at least two lateral rods to be connected together. 
   
     
     
         2 . The frame structure according to  claim 1 , wherein:
 the inner tube comprises a plurality of connection holes at intervals along the length direction of the first outer frame, and   the adjustment member is disposed on the outer tube to be connected to different ones of the plurality of connection holes, so as to adjust an extension length of the inner tube relative to the outer tube.   
     
     
         3 . The frame structure according to  claim 1 , wherein:
 the lateral rod clamping member comprises at least two position-limiting blocks, and   each of the at least two position-limiting blocks is disposed between adjacent lateral rods of the at least two lateral rods, and   adjacent position-limiting blocks of the at least two position-limiting blocks define one or more first slots for receiving one or more of the at least two lateral rods.   
     
     
         4 . The frame structure according to  claim 3 , wherein:
 two sides of two outermost position-limiting blocks of the at least two position-limiting blocks facing away from each other comprise two buckling walls extending downward along a height direction,   outsides of the two buckling walls are disposed with two blocking plates, and   two second slots for receiving two of the at least two lateral rods are defined between the two buckling walls and the two blocking plates.   
     
     
         5 . The frame structure according to  claim 4 , wherein:
 a length of the two buckling walls extending downward along the height direction is greater than a length of the two blocking plates.   
     
     
         6 . The frame structure according to  claim 5 , wherein:
 distal ends of the two buckling walls in the height direction extend in a horizontal direction to define a positioning surface configured to be matched with a bottom of the at least two lateral rods to inhibit upward movement of the lateral rod clamping member along the height direction.   
     
     
         7 . The frame structure according to  claim 1 , wherein:
 a first side of the first outer frame, a second side of the second outer frame facing the first side, and two sides of each of the at least two lateral rods along a thickness direction of each of the at least two lateral rods comprise a plurality of connecting fitting members that cooperate with the plurality of connecting members.   
     
     
         8 . The frame structure according to  claim 7 , wherein:
 the plurality of connecting fitting members are protrusions protruding outward along a thickness direction of the first outer frame, the second outer frame, or the at least two lateral rods, and   two sides of each of the protrusions in a width direction of the protrusions comprise a guiding rail extending along a height direction.   
     
     
         9 . The frame structure according to  claim 8 , wherein:
 two ends of each of the protrusions in the height direction respectively comprise an inlet and an outlet in communication with the guiding rail.   
     
     
         10 . The frame structure according to  claim 9 , wherein:
 the inlet is an inclined opening to increase an area of the inlet.   
     
     
         11 . The frame structure according to  claim 10 , wherein:
 each of the plurality of connecting members comprises one or more ribs slidably matched with the guiding rail,   a distal end of the one or more ribs along the height direction comprises a guiding inclined surface configured to be matched with the inclined opening in a guiding manner, and   a distal end of the guiding inclined surface is connected to the one or more ribs through a positioning surface.   
     
     
         12 . The frame structure according to  claim 1 , wherein:
 two opposite ends of the inner rod and the outer rod and two opposite ends of the inner tube and the outer tube are each disposed with a supporting leg.   
     
     
         13 . A stool, comprising the frame structure according to  claim 1 . 
     
     
         14 . A bed, comprising the frame structure according to  claim 1 .
