Turnover ladder beneficial to turnover operation
The invention relates to a turnover ladder facilitating turnover operation, which comprises a front ladder assembly and a rear ladder assembly, the front ladder assembly comprises a front ladder rod, the rear ladder assembly comprises a rear ladder rod, and the rear ladder rod is hinged with the front ladder rod through a hinge structure; the folding ladder is characterized in that the hinge structure comprises a front hinge frame fixed on the front ladder rod, at least two first locking grooves are formed in the front hinge frame, and a pushing part is arranged on one side of each first locking groove; the rear hinge frame is fixed to the upper end of the rear ladder rod, the front hinge frame is rotationally connected to the upper end of the rear hinge frame, a second locking groove is further formed in the rear hinge frame, the second locking groove can be aligned with the first locking groove in the rotating process of the rear hinge frame relative to the front hinge frame, and a placement step is arranged on the side portion of the second locking groove; a driving shaft is arranged in the middle of the locking pin in a penetrating mode, and the locking pin can be inserted into the first locking groove and the second locking groove which are aligned; and the elastic piece acts on the locking pin, so that the locking pin keeps the trend of moving upwards and swinging outwards. The turnover ladder has the advantages of being reasonable in structure and convenient to change the use state.
本发明涉及一种利于翻转操作的翻转梯，包括前梯架和后梯架，前梯架包括前梯杆，后梯架包括后梯杆，后梯杆通过铰链结构与前梯杆铰接；其特征在于：铰链结构包括固定在前梯杆上的前铰链架，前铰链架上至少开有两个第一锁定槽，第一锁定槽的一侧具有推动部；固定在后梯杆上端的后铰链架，前铰链架转动连接在后铰链架的上端，后铰链架上还设有第二锁定槽，后铰链架相对前铰链架转动过程中能使第二锁定槽与第一锁定槽对齐，第二锁定槽的侧部设有搁置台阶；锁定销，其中部穿设有驱动轴，锁定销能插入对齐的第一锁定槽和第二锁定槽；弹性件，作用于锁定销、使锁定销保持上移且向外摆动的趋势。本翻转梯具有结构合理、使用状态变换操作方便的优点。
