Description

内铰链式防盗窨井盖
本实用新型属于城市基础设施,具体涉及一种内铰链式防盗窨井盖的结构。
城市窨井盖普遍存在被盗现象,时常造成坠人等恶性伤人事故,给城市居民带来不安全隐患,专利申请99228126.1设计一种窨井盖防盗锁,较好地解决了窨井盖被盗问题,但在维修过程中井盖与井圈分开,若不放置明显警示牌,仍会给人造成危险。
本实用新型的目的在于:设计一种内铰链式防盗窨井盖,不仅防撬、防盗,而且打开时井盖与井座外圈相连呈90°角张开,醒目地提示行人注意前方障碍,避免事故发生。
本实用新型的目的是这样实现的:在窨井盖的反面上对称连接活动锁和内铰链,内铰链将井盖反面与井圈活动连接为一整体,活动锁的锁舌插入井圈上的锁孔内。
图1为本实用新型的局部剖视图
图中:1窨井盖、2活动锁、3井圈、4内铰链、5锁舌、6锁孔
下面结合附图介绍本实用新型的实施方法:
在窨井盖的反面上对称设置活动锁2和内铰链4,内铰链4连接窨井盖1与井圈3,活动锁2的锁舌5插入井圈3上的锁孔6内。
开启活动锁2,拉开窨井盖1,窨井盖1与井圈3相连呈90°夹角,维修人员可方便地进入井下作业,窨井盖直竖路面上,醒目地提示行人注意。
本实用新型结构简单,成本低廉,可广泛用于自来水、煤气、邮电等管道上,有效防撬、防盗、减少事故,保障人民生命财产安全。
