The invention discloses a writing board capable of being manually lifted and self-reset. The writing board comprises a body; the panel is rotationally connected with the body; one end of the lifting assembly is connected with the panel, the other end of the lifting assembly is rotationally connected with the body, the lifting assembly is provided with a plurality of gear grooves, gear pins and a limiting structure, and the gear pins slide on the gear grooves; the energy storage assembly is connected with the body and the panel; the gear pin moves to a preset threshold value, the acting force is removed, the gear pin is matched with the limiting structure, and the energy storage assembly drives the lifting assembly to return to the initial position; in the using process, the panel can be driven to adjust the height of the panel, the gear pins slide in the different gear grooves, and the adjusting effect of different heights is achieved; when the gear pin moves to the preset threshold value, the acting force is revoked, the gear pin is matched with the limiting structure, the gear pin directly returns to the initial position, the rapid reset effect is achieved, the structure can rapidly return to the initial position, attention of operators cannot be affected, and operation is faster and more convenient.

    本发明公开了一种可手动升降自复位的书写板,包括:本体;面板与本体为转动连接;升降组件一端与面板连接,升降组件另一端与所本体转动连接,升降组件设有若干个档位槽、档位销以及限位结构,档位销在档位槽上滑动;储能组件连接本体与面板;档位销运动至预设阈值,撤销作用力,档位销与限位结构配合,储能组件带动升降组件回复至初始位置;在使用过程中可以驱动面板实现调节面板的高度,档位销在不同的档位槽内滑动,实现不同高度的调节效果;档位销运动至预设阈值,撤销作用力,档位销与限位结构配合,档位销直接回复到初始位置,实现快速复位效果,此结构可以快速回复到初始位置,不会影响到操作人员的注意力,使得操作更加快捷、方便。
