Herringbone ladder with folding stool plate
The invention discloses aherringbone ladder with a folding stool plate. The herringbone ladder with the folding stool plate comprises two groups of inclined ladder frames, each ladder frame comprisestwo ladder frame rods, a plurality of foot bars are fixed between the ladder frame rods, the upper ends of the ladder frame rods are inserted and fixed to an n-shaped top plate, and the two groups ofladder frames are hinged through a plurality of groups of hinge chain frames; each hinge chain frame comprises a first inserting plate and a second inserting plate, the first inserting plates and thesecond inserting plates are inserted and fixed into the top plate of the two groups of ladder frames correspondingly, [-shaped outer articulation pieces are formed on the lower end faces of the firstinserting plates, and vertical inner articulation pieces are formed on the lower end faces of the second inserting plates; the inner articulation pieces are inserted into the outer articulation piecesand are articulated with the outer articulation pieces through articulation shafts; and the top plate abuts against the upper end faces of the outer articulation pieces.
本发明公开了一种带折叠凳板的人字梯，包括两组呈倾斜的梯架，梯架包括两根梯架杆，梯架杆之间固定有若干踏杆，梯架杆的上端插接固定在“冂”字形的顶板，两组梯架通过若干组铰接链架相铰接；铰接链架包括第一插板和第二插板，第一插板和第二插板分别插接固定在两组梯架的顶板内，第一插板的下端面上成型有“匚”字形的外铰接件，第二插板的下端面成型有竖直的内铰接件，内铰接件插接在外铰接件内并通过铰接轴和外铰接件相铰接；所述的顶板抵靠在外铰接件的上端面上。
