The lightweight folding
bed comprises a
bed surface structure and a plurality of supporting structures arranged at the bottom of the
bed surface structure in a self-locking manner, the bed
surface structure comprises a fabric body and a bed surface
pipe used for supporting the structural strength of the fabric body, the supporting structure comprises a transverse
pipe and supporting leg assemblies arranged at the two ends of the transverse
pipe in a hinged mode, and clamping pieces self-locked with the bed surface pipe are formed at the tops of the supporting leg assemblies; the supporting leg
assembly comprises a supporting pipe and a leg pipe which are arranged on the transverse pipe in a hinged mode, the end of the supporting pipe is hinged to the middle of the leg pipe, a sliding piece for achieving folding of the supporting leg
assembly is hinged to the end of the transverse pipe, and the leg pipe forms a lever structure facilitating deformation of the supporting leg
assembly; compared with the prior art, by arranging the variable supporting assembly, when the supporting assembly receives the gravity, the clamping piece receives the tensioning force from the gravity and the fabric body at the same time, self-locking of the supporting assembly and the bed surface structure is achieved through the arrangement of the clamping piece, the whole structure tends to be tighter, and the use stability of the whole structure is ensured.
