The invention relates to a folding escape ladder. The folding escape ladder comprises a plurality of ladder sections which are hinged in sequence, wherein any two adjacent ladder sections are hinged through a first hinge shaft so as to be capable of relatively rotating between an unfolding position and a folding position; a locking mechanism is arranged between every two hinged ladder sections, each locking mechanism comprises a stop piece and a clamping stop piece, and the stop pieces and the clamping stop pieces are matched in a releasable mode; when the two hinged ladder sections are located at the folding position, the stop piece is disengaged from the clamping stop piece, so that relative rotation between the two hinged ladder sections is allowed; and when one of the two hinged laddersections rotates to the unfolding position relative to the other one of the two hinged ladder sections, the stop piece is matched with the clamping stop piece to limit the relative rotation between the two hinged ladder sections. By means of the technical scheme, the folding escape ladder can be automatically locked while being unfolded, so that the operation time of the escape ladder is shortened.

    本公开涉及一种折叠式逃生梯,包括依次铰接的多个梯段,任意相邻的两个梯段之间通过第一铰接轴铰接以能够在展开位置和折叠位置之间相对转动,相铰接的两个梯段之间设置有锁止机构,锁止机构包括止动件和卡止件,止动件与卡止件可释放地配合,当相铰接的两个梯段位于折叠位置时,止动件与卡止件脱离配合,以允许相铰接的两个梯段之间的相对转动;当相铰接的两个梯段中的一者相对于相铰接的两个梯段中的另一者转动到展开位置时,止动件与卡止件实现配合,以限制相铰接的两个梯段之间的相对转动。通过上述技术方案,本公开提供的折叠式逃生梯能够在展开的同时自动锁止,缩短了逃生梯的操作时间。
