The invention relates to a self-closing floor drain structure. The structure comprises a main plate provided with a drainage hole and a drainage barrel extending downwards from the lower surface of the main plate, wherein a self-closing door capable of being sealed and blocked in the section direction is arranged in the drainage barrel and comprises a pair of symmetrically-arranged door bodies, the door bodies are hinged to the wall of the drainage barrel through fixing shafts, balancing weights are arranged on the door bodies, the self-closing door has a closed state and an open state, and the self-closing door is kept in the closed state under the actions of the balancing weights when the self-closing door is not affected by external force; and when the acting force of liquid flowing down from the drainage hole on the door bodies is larger than the acting force of the corresponding balancing weights on the door bodies, the ends, close to each other, of the two door bodies turn over downwards, and the self-closing door is in the open state. The structure adopts a normally-closed self-closing door body structure, and the self-closing door can realize a normally-closed state, so that odor of a public sewer line is prevented from returning upwards, the whole structure is simple and reliable, mechanical structures are adopted, and the use and the maintenance are more convenient.
本发明涉及一种自闭式地漏结构，包括开设有下水孔的主板、从主板的下表面向下延伸设置的下水筒，下水筒内设置有能够沿截面方向密封封堵的自闭门，自闭门包括对称设置的一对门体，门体通过固定轴铰接安装在下水筒的壁上，门体上设置有配重块，自闭门具有关闭状态和打开状态，在不受到外力作用时，配重块的作用使得自闭门保持在关闭状态；当从下水孔流下的液体对门体的作用力大于对应的配重块对门体的作用力时，两个门体的相靠近的一端向下翻转，自闭门处于打开状态。该结构采用常闭自闭式的门体结构，其中的自闭门能够实现常闭的状态，从而实现避免公共下水管道的臭气返上来，整体结构简单、可靠，且均采用机械式结构，使用、维护更便捷。
