Foldable ladder
The invention provides a foldable ladder and relates to the technical field of climbing tools, the foldable ladder comprises a main ladder and an auxiliary ladder, the top end of a ladder frame of the auxiliary ladder is connected to a ladder frame of the main ladder through a hinge mechanism; the hinge mechanism comprises a main ladder hinge piece, an auxiliary ladder hinge piece and a shaft pin locking assembly connecting the main ladder hinge piece and the auxiliary ladder hinge piece, the main ladder hinge piece comprises a first hinge piece, a second hinge piece and a third hinge piece which are sequentially connected to form a Z shape, and in the pedal extending direction of the main ladder, the first hinge piece is fixed to the outer side face of a ladder frame of the main ladder, and the second hinge piece is fixed to the outer side face of a ladder frame of the auxiliary ladder. The first hinge piece is located on the outer side of the third hinge piece. The auxiliary ladder hinge piece is fixed to the top end of the ladder frame of the auxiliary ladder, and the shaft pin locking assembly penetrates through the third hinge piece and the auxiliary ladder hinge piece and enables the auxiliary ladder hinge piece to be connected to the third hinge piece. According to the folding ladder, the technical problems that a rotating structure between a main ladder and an auxiliary ladder of an existing folding ladder is basically completely or mostly exposed, is easily scraped, bumped and damaged or is accidentally unlocked to cause safety accidents and is difficult to store are solved.
本发明提供一种可折叠梯具，涉及登高工具的技术领域，包括主梯和副梯，副梯的梯框顶端通过铰链机构连接于主梯的梯框；铰链机构包括主梯铰链片、副梯铰链片以及连接主梯铰链片和副梯铰链片的轴销锁合组件，其中，主梯铰链片包括依次连接呈“Z”字形的第一铰链片、第二铰链片和第三铰链片，在主梯的踏板延伸方向上：第一铰链片固定于主梯的梯框外侧面，且第一铰链片位于第三铰链片的外侧；副梯铰链片固定于副梯的梯框顶端，轴销锁合组件穿过第三铰链片和副梯铰链片并将副梯铰链片连接于第三铰链片。本发明缓解了现有折叠梯主梯和副梯间转动结构基本完全或大部分外露，易刮擦磕碰损坏或意外解锁造成安全事故，且难以收纳的技术问题。
