The invention discloses a ladder with an adjustable telescopic height, The ladder comprises a first side beam, a first pedal plate, a second side beam, a second pedal plate and a supporting beam; the first pedal plate is installed on the outer surface of the first side beam; the second side beam is arranged in the first side beam; the second pedal plate is installed on the outer surface of the second side beam; the supporting beam is installed on the back face of the first side beam; the bottom of the first side beam is fixedly connected with a base; the second side beam comprises sliding grooves, an inner groove, a clamping head, a telescopic spring and a clamping groove; the sliding grooves are formed in the left side and the right side of the second side beam; the inner groove is formed in the second side beam; the clamping head is arranged in the inner groove; and one end of the telescopic spring is fixedly connected with the inner wall of the inner groove. Due to the fact that the ground is uneven, second supporting legs are arranged, the second supporting legs can be stably placed on the uneven ground through pressing mechanisms and contraction blocks which are arranged in the second supporting legs, the safety in the using process is improved, the shaking degree is reduced, and potential safety hazards are reduced.
本发明公开了一种可调节伸缩高度的梯子，包括侧梁一、脚踏板一、侧梁二、脚踏板二和支撑梁，所述脚踏板一安装在侧梁一外表面，所述侧梁二设置在侧梁一内部，所述脚踏板二安装在侧梁二外表面，所述支撑梁安装在侧梁一背面，所述侧梁一底部固定连接有底座，所述侧梁二包括滑槽、内槽、卡头、伸缩弹簧和卡槽，所述滑槽设置在侧梁二左右两侧，所述内槽设置在侧梁二内部，所述卡头设置在内槽内部，所述伸缩弹簧一端与内槽内壁固定连接，本发明通过设置支撑脚二是由于地面的凹凸不平，通过内部设置的按压机构和收缩块可以在凹凸不平的地面上放置平稳，提高使用过程中的安全性，减少了晃动程度，提高了安全隐患。
