The invention discloses a multifunctional telescopic ladder. Box bodies are fixed to both sides of the tops of pedals, pull rods are arranged below the pedals, movable rods inserted into the box bodies are fixed to the two sides of the pull rods correspondingly, the tops of the movable rods are fixed to the tops of inner cavities of the box bodies through tension springs, one sides of the box bodies are slidably connected with inclined tongues, one sides, located in the inner cavities of the box bodies, of the inclined tongues are hinged to connecting rods, one sides, away from the inclined tongues, of the connecting rods are hinged to one sides of the movable rods, and the outer sides of a second cylinder barrel, a third cylinder barrel and a column body are fixedly provided with ratchetbars matched with the inclined tongues. According to the ladder, the ladder is directly erected on a building, the ladder is elongated through inflation, whether the ladder reaches a target height requirement can be intuitively judged, the ladder length can be adjusted without target height judgment through visual inspection, and the tedious operation of putting down the ladder multiple times to adjust the ladder length due to inaccurate visual inspection is avoided.
本发明公开了多功能伸缩梯子，踏板的顶部两侧均固定有盒体，踏板的下方设有拉杆，拉杆的两侧分别固定有插入于盒体内的活动杆，活动杆的顶部通过拉簧固定于盒体的内腔顶部，盒体的一侧滑动连接有斜舌，斜舌位于盒体内腔的一侧铰接有连杆，连杆远离斜舌的一侧铰接于活动杆的一侧，第二缸筒、第三缸筒和柱体的外侧均固定有与斜舌相匹配的棘齿条。本梯子通过将梯子直接搭靠在建筑物上，通过充气使得梯子进行伸长，可以直观判断梯子是否达到目标高度要求，从而可以无需根据目测判断目标高度来进行调整梯长，避免因目测不精确导致的需要多次放倒梯子调整梯长的繁琐操作。
