Portable engineering folding ladder
The invention provides a portable engineering folding ladder, and relates to the technical field of design of engineering ladders for buildings. The portable engineering folding ladder comprises a left ladder assembly, a right ladder assembly, two rear support frames and a plurality of pedals; the two rear support frames comprise support sleeves and telescopic rods; each telescopic rod is arranged in and penetrates the installation hole in the upper end of the corresponding support sleeve in an up-and-down motion manner; a limiting stopper is fixedly connected to the upper end of each telescopic rod; a protective guard is arranged between the two limiting stoppers; the upper ends of the left ladder assembly and the right ladder assembly are hinged to the corresponding limiting stoppers; stiffeners are hinged between the left ladder assembly and the corresponding rear support frame and between the right ladder assembly and the corresponding rear support frame; an operating stage is arranged between the two stiffeners. The portable engineering folding ladder is more convenient and safer to use, and carrying and storage are more convenient.
