The invention provides a manual lifting platform. The manual lifting platform comprises a ratchet hand crank, a product placing panel, a platform upper frame, platform lifting arms and a platform lower frame; the platform upper frame and the platform lower frame are directly connected and matched with the platform lifting arms for use; the platform lifting arms comprise a first lifting arm and a second lifting arm, and the first lifting arm and the second lifting arm are arranged in a scissor type; one end of the first lifting arm is fixedly connected to the platform upper frame, and the otherend of the first lifting arm is connected to the platform lower frame in a sliding mode; one end of the second lifting arm is connected to the platform upper frame in a sliding mode, and the other end of the second lifting arm is fixedly connected to the platform lower frame; and the ratchet hand crank drives a gear module mechanism to rotate, and the platform lifting arms can enable the productplacing panel to ascend or descend. According to the manual lifting platform, by adopting the technology that the lifting arms are directly connected with the platform upper frame and the platform lower frame, connecting holes on two sides are parallel and concentric in a two-head connection mode, the good synchronism is achieved, and the lifting process is smoother and more stable.

    本发明提供了一种手动升降平台,包括:棘轮手摇柄、产品放置面板、平台上框架、平台升降臂和平台下框架;平台上框架与平台下框架直接与平台升降臂连接配合使用;平台升降臂包括:第一升降臂和第二升降臂,第一升降臂和第二升降臂呈剪叉式设置;第一升降臂的一端固定连接在平台上框架上,另一端滑动连接在平台下框架上;第二升降臂的一端滑动连接在平台上框架上,另一端固定连接在平台下框架上;棘轮手摇柄带动齿轮模组机构转动,平台升降臂能够使产品放置面板上升或者下降。本发明通过采用升降臂直接连接平台上框架和平台下框架的技术,采用两头连接的方式,两边的连接孔位平行且同心,达到同步性好,在升降过程中更加平滑、稳定。
