The invention provides a multifunctional high-strength folding domestic ladder. The multifunctional high-strength folding domestic ladder comprises two parallel front tubes and two parallel back tubes, wherein the front tubes and the back tubes are mutually hinged two by two; a telescopic handrail is connected to the top ends of the two front tubes; the telescopic handrail comprises two telescopicrods inserted into the front tubes; a cross rod is connected to the top ends of the two telescopic rods through connecting assemblies. The handrail of the multifunctional high-strength folding domestic ladder adopts a telescopic structure, and can be retracted during packaging or transportation, so that the volume of a packaging box during the transportation is reduced; through connection of theconnecting assemblies at bent pipes, the problems of infirmness, exposure, bent pipe sunkness, deformation and the like during rivet connection are solved.
Description
technical field [0001] The invention belongs to the technical field of ladders, in particular to a multifunctional high-strength folding household ladder. Background technique [0002] A Chinese patent for a household folding ladder, the application number is 201020667593.4, discloses a folding ladder, including a front tube, a rear tube and a pedal, the front tube and the rear tube are hinged, the pedals are installed on the front tube and the rear tube, and one end It is connected with the front pipe, and the other end is connected with the rear pipe. There are several grooves on the surface of the pedal, and anti-slip decorative strips are installed in the grooves. The defect of this structure is that the overall visual sense of the ladder is not strong, and the top handrail is made of plastic parts. Connected with aluminum pipes and riveted with hollow rivets, the connection strength is not enough, the appearance is not good enough, and the bent pipe is easy to sag, and ...
