The invention discloses a portable telescopic hanging ladder. The portable telescopic hanging ladder comprises a telescopic ladder body, the telescopic ladder body comprises telescopic legs on the twosides and a climbing rod installed between the telescopic legs; anti-skid assemblies are arranged at the bottoms of the telescopic legs, and each anti-skid assembly comprises a U-shaped anti-skid base and a rotating shaft; horizontal through holes are formed in the bottoms of the telescopic legs, the rotating shafts are arranged in the through holes in a penetrating mode, and rotating grooves areformed in the inner walls of the two sides of each anti-skid base; the two ends of each rotating shaft are rotatably connected with the corresponding rotating grooves; and the telescopic legs are rotatably connected with the anti-skid bases through the rotating shafts. According to the device, on the basis of increasing the contact area between the telescopic ladder and the ground, the friction with the ground can be increased, no matter whether the telescopic ladder is erected on a horizontal plane or a slope surface, the possibility of slipping of the telescopic ladder can be effectively reduced, the stability of the telescopic ladder is improved, and potential safety hazards are reduced.
本发明为一种便携式伸缩挂梯，包括伸缩梯，所述伸缩梯包括两侧的伸缩腿和安装在所述伸缩腿之间的攀爬杆，所述伸缩腿的底部设有防滑组件，所述防滑组件包括呈“凹”字型的防滑底座和转动轴，所述伸缩腿的底部设有水平的通孔，所述转动轴穿设在所述通孔内，所述防滑底座的两侧内壁设有转动槽，所述转动轴的两端与所述转动槽转动连接，所述伸缩腿通过所述转动轴与所述防滑底座转动连接，本装置在增大伸缩梯与地面的接触面积的基础上，提高与地面的摩擦力，无论是在水平面上架设伸缩梯还是在坡面上架设伸缩梯，都能够有效减少伸缩梯打滑的可能性，提高伸缩梯的稳定性，减少安全隐患的发生。
