The invention discloses a trolley comprising a base and a pushing handle, rolling wheels are arranged below the base, a lifting platform is arranged on the base, a mounting box is arranged on one side of the base, and the pushing handle is connected with the mounting box through a rotating assembly. When the pushing handle is located at the working position, an elastic piece has a trend of pulling a cam to rotate so as to keep a second connecting end higher than a first connecting end; when the pushing handle is located at the storage position, the elastic piece has a trend of pulling the cam to rotate so that a second connecting end can be kept lower than the first connecting end, and a locking piece is further arranged between the pushing handle and an installation box. And the locking piece is used for locking the pushing handle at the working position. By arranging a rotating assembly, a worker does not need to support the pushing handle to unfold and fold in the whole process, folding and storage are facilitated, and meanwhile the storage operation is simplified; by arranging the locking piece, the pushing handle can be locked at the working position, and the pushing handle is prevented from rotating in the process of using the trolley.
本发明公开一种手推车,包括底座和推手,底座的下方设置有滚轮,底座上设置有升降平台,底座的一侧设置有安装箱,推手通过转动组件和安装箱连接,当推手处于工作位置时,弹性件具有拉动凸轮转动以使第二连接端保持高于第一连接端的趋势,当推手处于收纳位置时,弹性件具有拉动凸轮转动以使第二连接端保持低于第一连接端的趋势,推手和安装箱之间还设置有锁定件,锁定件用于将推手锁定在工作位置。通过设置转动组件,不需要工作人员全程搀扶推手进行展开和收纳,在折叠便于收纳同时,简化了收纳操作;通过设置锁定件,可以将推手锁定在工作位置,避免在使用手推车的工程中推手发生转动。
