AI Technical Summary
Existing loading and unloading trucks have poor passing through when encountering small obstacles and have poor user experience. Especially because the design of the mobile board limits the roller diameter, the loading and unloading trucks are unstable during use and are prone to overturn.
A loading and unloading truck is designed, including a loading and unloading truck main body and a lifting frame. Lifting plates are provided on both sides of the lower part of the lifting frame. The loading and unloading truck main body is symmetrically provided with an expansion part and a main roller wheel. The moving plate guide groove is in an inverted U-shaped shape. The movable plate can enter the hollow part of the lifting plate, and support is achieved through the movable roller support rod and guide sleeve. The main roller, the first roller and the movable roller can be supported on the same horizontal plane at the same time, improving the passing and stability.
By setting the diameters of the main roller, the first roller and the movable roller to be larger, the limitation of the movable plate guide groove is avoided, and the passing and stability of the loading and unloading truck is improved. It is not easy to overturn during use, and the experience is better.
