Multifunctional power-driven stair-climbing trolley capable of moving freely in narrow space

TLDR: In this article, a multifunctional power-driven stair-climbing trolley capable of moving freely in a narrow space is described, which is used for solving problems that a similar product sways forward and backward when in step movement with a large span and is not safe, the similar product is difficult to move in the narrow space, and the similar products can not integrate functions of stair climbing, walking assistance and push walking on one and is few in function.

Abstract: The utility model provides a multifunctional power-driven stair-climbing trolley capable of moving freely in a narrow space, and relates to medical machinery. The multifunctional power-driven stair-climbing trolley capable of moving freely in the narrow space is used for solving problems that a similar product sways forward and backward when in step movement with a large span and is not safe, the similar product is difficult to move in the narrow space and is not practical, and the similar product can not integrate functions of stair climbing, walking assistance and push walking on one and is few in function. The multifunctional power-driven stair-climbing trolley capable of moving freely in the narrow space mainly comprises a trolley frame, handles, crawler belts, waling wheels and a sliding disc and is characterized in that the lengthened crawler belts are installed on the trolley frame so as to solve safety problems, the sliding disc is installed between the two crawler belts, and a lifting function of the sliding disc enables the crawler belts and the walking wheels to be off the land or on the land. When the sliding disc is in a supporting state, the trolley body can turn and move easily in the narrow space so as to solve practical problems. The trolley is enabled to integrate the functions of stair climbing, walking assistance and push walking on one by controlling different relative heights among the sliding disc, the crawler belts and the walking wheels, so the problem of few function is solved. The trolley is mainly used for the old, the weak, the sick and the disabled to go upstairs or downstairs and to have outdoor activities.
