The invention relates to the technical field of transportation instruments, in particular to a telescopic frame. The technical problems to be solved by the invention are that telescopic folding cannotbe realized and the supporting effect is poor. In order to solve the problems in the prior art, the telescopic vehicle frame is composed of a vehicle frame body and an auxiliary mechanism, the vehicle frame is telescopic by arranging the first connecting pipe, the sleeve and the second connecting pipe, and when the vehicle frame is not used, the first connecting pipe and the second connecting pipe can be contracted in the sleeve; the first connecting pipe can be slidably connected into the second connecting pipe in a sleeved mode, then the connecting rod and the supporting rod are rotated toenable the frame to be in a contraction state, and therefore the space occupied by the frame is reduced; by arranging the auxiliary mechanism, during use, the vehicle frame in the extending state canbe moved to the position beside an object needing to be transported, short-distance goods and materials carrying is achieved, and when the vehicle frame stops, the rotary knob is twisted, so that themoving wheels are lifted up, the supporting legs make contact with the ground, and the vehicle frame is more stable.
本发明涉及运输器械技术领域,尤其涉及伸缩式车架。本发明要解决的技术问题是不能伸缩折叠和支撑效果差。为了解决上述技术中的问题,本发明提供伸缩式车架,本发明由车架本体和辅助机构组成,通过设置第一连接管、套管和第二连接管,使车架可伸缩,当不使用车架时,能够将第一连接管和第二连接管收缩在套管内,并且第一连接管能够滑动套接在第二连接管内,然后旋转连接杆和支撑杆,使车架变成收缩状态,从而减小车架所占的空间;通过设置辅助机构,在使用时,能够将伸展状态的车架移动至需要运输的物品旁,实现短距离搬运物资,当车架停留时,扭动旋钮,从而将移动轮升起来,使支脚接触地面,使车架更加稳定。
