Overturn-preventing straight ladder
The invention belongs to the technical field of climbing tools, and particularly relates to an anti-overturning straight ladder which comprises a main body composed of side rods and cross rods, rotatable supporting leg steering machines are arranged at the bottoms of the side rods, the supporting leg steering machines are hinged to supporting legs, the number of the supporting legs is four, and the bottom of each side rod is connected with two supporting legs; the supporting legs are vertical in the initial state and are close to the side rods, the supporting legs can be unfolded to make contact with the ground under the action of the supporting leg driving mechanisms, and the supporting legs can be fixed under the action of the locking mechanisms after being unfolded. According to the invention, the ladder is not easy to overturn under the condition that there is no person on the ladder, and good stability can be ensured.
本发明属于攀登工具技术领域，具体涉及一种防倾覆直梯，包括由边杆和横杆组成的主体，边杆底部设有可转动的支腿转向机，支腿转向机与支腿铰接，支腿设有四条，每个边杆底部各连接两条；支腿初始状态时为竖向且与边杆贴近，在支腿驱动机构的作用下支腿可展开与地面接触，支腿展开后可在锁止机构作用下固定。本发明在没有人扶梯子的情况下，梯子不易倾覆，能够保证良好的稳定性。
