Abstract
A frame structure includes a frame body and an auxiliary frame fixedly connected to the frame body. The frame body has a front bracket and a frame base. The lower end of the front bracket does not connect with the frame base. The upper end portion of the auxiliary frame is connected to the front bracket of the frame body, and the lower end of the auxiliary frame is connected to the frame base at the rear of front wheels of the frame. A trolley with the frame structure can prevent it from leaning forward or overturning, which increases security and stability.
