The invention discloses a wear-resisting and anti-falling aluminum ladder. The wear-resisting and anti-falling aluminum ladder comprises first supporting rods and transverse rods, limiting clamping grooves are formed inside the upper ends of the first supporting rods, positioning lead screws are arranged inside the limiting clamping grooves, positioning bolts are fixed to the two sides of a handle, bases are arranged at the lower ends of the first supporting rods, first limiting rotating shafts are fixed to the bottoms of the four sides of each base, fixing plates are connected to the outer sides of the first limiting rotating shafts, second limiting rotating shafts are fixed to the upper ends of the fixing plates, and limiting clamping nails are connected to the outer sides of the secondlimiting rotating shafts. The contact area between the bases and the ground can be increased through the multiple sets of fixing plates and rubber non-slip mats which are arranged, the friction forcebetween the bases and the ground is increased, falling during use can be avoided, the arranged limiting clamping nails can be inserted underground in the muddy ground, then the bases can be fixed morefirmly, through the arranged second limiting rotating shafts, the limiting clamping nails can be stored so that the placement states of the limiting clamping nails can be flexibly changed.
本发明公开了一种耐磨防摔铝梯，包括第一支撑杆和横杆，所述第一支撑杆的上端内部开设有限位卡槽，且限位卡槽的内部设置有定位丝杆，所述把手的上两侧固定有定位螺栓，所述第一支撑杆的下端设置有底座，且底座的四边底部均固定有第一限位转轴，所述第一限位转轴的外侧连接有固定板，且固定板的上端固定有第二限位转轴，所述第二限位转轴的外侧连接有限位卡钉。通过设置的多组固定板与橡胶防滑垫能够增加底座与地面之间的接触面积，使其之间的摩擦力增加，可以避免使用时摔倒，通过设置的限位卡钉可以在泥地中插入地底，可以使得底座固定的更加牢固，并且设置的第二限位转轴可以放对限位卡钉进行收放，使其能够灵活地改变其放置状态。
