The invention relates to a multifunctional push-pull vehicle. The problems that in the prior art, the size of a chassis of a push-pull vehicle cannot be adjusted, and the push-pull vehicle is large inoccupied space and inconvenient to fold and store are solved. The multifunctional push-and-pull vehicle comprises a chassis assembly which comprises a rear chassis, a middle chassis fixedly connectedwith the rear chassis and a front chassis horizontally limited to slide with the middle chassis through a limiting assembly; a wheel assembly which comprises a self-locking universal wheel set, a first wheel set and a second wheel set which are located at the bottom of the rear chassis, the bottom of the middle chassis and the bottom of the front chassis respectively. The front chassis is pulledoutwards, so that the middle chassis overlapped with the bottom of the front chassis is exposed, the total area borne by the chassis assembly is increased, the middle chassis and the front chassis arelimited through the limiting assembly, transportation of goods can be achieved by pulling the push-pull vehicle, and therefore the adjustable function of the push-pull vehicle chassis is achieved; and great convenience is provided for transportation of goods.

    本发明涉及一种多功能推拉车,解决了现有技术中推拉车底盘大小无法调节和推拉车占用空间大不便于折叠收纳的问题。一种多功能推拉车,包括:底盘组件,所述底盘组件包括后底盘、与后底盘固定连接的中底盘和与中底盘通过限位组件水平限位滑动的前底盘;车轮组件,所述车轮组件包括分别位于后底盘、中底盘和前底盘底部的自锁式万向轮组、第一车轮组和第二车轮组。本发明通过向外拽出前底盘,以使得与前底盘底部重叠的中底盘露出,底盘组件所能承载的总面积变大,中底盘与前底盘之间通过限位组件限位,通过拉动推拉车,即可实现货物的运输,从而实现了推拉车底盘的可调节功能,为货物的运输提供了很大的便捷。
