Description
本实用新型是一种工业地下管道地面上用的可防止不法分子偷窃的防盗井盖。其是在普通井盖的基础上经改进后，即可达到防盗之目的。
本实用新型的任务是设计一种结构简单、操作方便，易制造的防盗井盖。
下面结合附图介绍本实用新型的具体实施例。
附图1是本实用新型的俯视图。
附图2是本实用新型附图1中的A－A剖面图
本实用新型的结构是：井盖1的左侧突出一块与井座2相配合的轴为中心的活动轴4，其上部有个三角形凹槽7，井盖1的下部有两弧度相等的园弧槽板3，两园弧槽板3上均有以井盖1外侧的活动轴4之轴心为园心的120°左右的槽，此槽向上直至井盖1的下端面。井座2的左侧突出一块与井盖1的活动轴4相配合的带园弧的搭子5，搭子5的右侧有块连接板6，连接板6的端头有个连接销8将井盖1下部的两园弧槽板3连接起来，再将连接销8的端头焊上挡块（挡块所在位置应以连接销8能有足够量的轴向窜动为宜），井盖1即可自如的翻开，而不易被不法分子偷窃。
另外井盖1上有3个枣核形吊装孔，而其表面的摩擦网纹及下部的加强筋附图中略掉。
本实用新型是这样实现设计任务的：工作者一般是站立于井盖1有活动轴4一侧，开启井盖1时，用钩子插入井盖1上正对着工作者的吊装孔中，然后用力向后拉起井盖1，井盖1则以其外侧的活动轴4之轴心为园心作逆时针翻转，其下的两园弧槽板3受连接销8的限制两槽口沿连接销8表面亦作逆时针滑动。这样即保证了活动轴4只能在搭子5园弧槽内转动，而不会脱槽，又保证了井盖1始终以活动轴4之轴心为园心进行翻转，而且不会出现左右摆动。当井盖1逆时针翻转到约120°角度时，其上的三角形凹槽7与搭子5外侧的垂直立板上端面及内壁吻合，井盖1便停靠于此。如果井盖1下部的两园弧槽板3上的槽口弧度合适，那么槽口的末端恰好也被连接销8限死，即限制了井盖1的翻转角度，使之停靠更牢。
井盖1的闭合过程与上述的开启过程完全相反，这里不在叙述。
