The invention relates to the technical field of trolleys, and discloses a multifunctional trolley which comprises a main body, two supporting frames are rotationally connected to the side wall of the main body, a scissor-type connecting rod is rotationally connected to the back faces of the two supporting frames, and a connecting rod is rotationally connected to the end, away from the supporting frames, of the scissor-type connecting rod. The ends, away from the scissor-type connecting rods, of the connecting rods are rotationally connected with the side walls of the supporting frames, and spring frames are rotationally connected to the front face and the back face of the body. When an auxiliary plate slides upwards, a first spring rod is driven to synchronously move upwards, the first spring rod slides in a heart-shaped groove when moving upwards, and when the first spring rod slides to the corner of the heart-shaped groove, the first spring rod can be fixed when the device is folded and stored; the situation that the trolley is unfolded in the moving process after being folded or under the influence of the outside world is reduced, and then the stability of the device in the folded state can be enhanced.
本发明涉及手推车技术领域,且公开了一种多功能手推车,包括主体,主体的侧壁转动连接有两个支撑架,两个支撑架的背面转动连接有剪叉式连杆,剪叉式连杆远离支撑架的一端转动连接有连接杆,连接杆远离剪叉式连杆的一端与支撑架的侧壁转动连接,主体的正面与背面均转动连接有弹簧架。本发明当辅助板向上滑动时会带动弹簧杆一同步上移,弹簧杆一在上移时会在心形槽的内部进行滑动,当弹簧杆一滑动到心形槽上的拐角处时便可以在装置折叠收纳时进行固定,减少小车在折叠后移动的过程或在外界的影响下出现展开的情况,进而可以增强此装置在折叠状态下的稳定性。
