The invention relates to the technical field of extension ladders, and particularly discloses a rapid folding type extension ladder, an extension ladder body comprises extension ladder rods, pedals, hinge pieces and buttons, the buttons are arranged at the end parts of the bottom surfaces of the pedals and are used for releasing a locking state between corresponding sleeve rods when being pressed, and a grab rail is fixed at the top end of one extension ladder rod; each extension part comprises a plurality of bottom pipes and a transverse connecting piece, the bottom pipes are matched with the bottom ends of the telescopic ladder rods in a sleeving manner, the two ends of each transverse connecting piece are matched with the top ends of the paired bottom pipes in a sleeving manner, and locking linkage parts for locking the top ends of the bottom pipes and the bottom ends of the telescopic ladder rods in the radial direction are arranged at the two ends of each transverse connecting piece; linkage rods are arranged on the inner sides of the bottom pipes in parallel, the top ends of the linkage rods are in linkage with the locking linkage parts, and the linkage rods unlock the locking state of the locking linkage parts through vertical movement; a driving mechanism for achieving vertical movement of the linkage rods through treading is arranged between the bottoms of the two paired bottom pipes; and the problem that the operation is inconvenient when the extension ladder is folded is solved.
本发明涉及伸缩梯技术领域，具体公开了一种快速收合型伸缩梯，伸缩梯本体包括可伸缩梯杆、踏板、铰接件以及设于踏板底面端部且用于受压时解除对应套杆之间锁定状态的按钮，其中一个可伸缩梯杆的顶端固定有扶手杆，延伸部包括分别与可伸缩梯杆底端套接匹配的多个底管以及两端分别与成对的底管顶端套接匹配的横向连接件，横向连接件的两端部分别设有沿径向将底管顶端与可伸缩梯杆底端锁死的锁定联动部，底管的内侧平行设有顶端与锁定联动部相联动并通过竖向运动解除锁定联动部锁死状态的联动杆，成对的两个底管底部之间设有通过脚踩实现联动杆竖向运动的驱动机构；解决了伸缩梯收合时存在的操作不便的问题。
