The invention relates to a quick-opening manhole cover. The quick-opening manhole cover comprises a quick-opening manhole ring and a quick-opening manhole cover, wherein one side of the quick-opening manhole ring is fixedly connected with the left end of a first connecting plate, one side of the quick-opening manhole cover is fixedly connected with the left end of a second connecting plate, the left side of the first connecting plate is hinged to the right end of the second connecting plate, a booster is installed between the first connecting plate and the second connecting plate, one side of the quick-opening manhole ring is integrally and fixedly connected with the first connecting plate through welding or casting or is detachably and fixedly connected with the first connecting plate through a thread structure, and one side of the quick-opening manhole cover is integrally and fixedly connected with the second connecting plate through welding or casting or is detachably and fixedly connected with the second connecting plate through a thread structure. The quick-opening manhole cover has the advantages of the simple structure and small occupied space; and when the manhole cover is large in size and heavy in weight, the manhole cover can be opened with small force, the requirement for operating personnel is low, the opening speed is high, and the manhole cover is prevented from being collided.
本发明涉及一种快开人孔盖，包括快开人孔环和快开人孔盖，快开人孔环一侧固定连接第一连接板左端，快开人孔盖一侧固定连接第二连接板左端，第一连接板左侧铰接第二连接板右端，第一连接板与第二连接板之间安装助力器，快开人孔环一侧通过焊接或者铸造一体式固定连接第一连接板；或者通过螺纹结构可拆卸固定连接第一连接板，快开人孔盖一侧通过焊接或者铸造一体式固定连接第二连接板；或者通过螺纹结构可拆卸固定连接第二连接板。本发明结构简单，占用空间小；当人孔盖尺寸较大、质量较重时，需要较小的力就能开启，对操作人员要求较小，且开启速度较块，避免造成人孔盖磕碰。
