Description

防盗井盖
技术领域
本发明涉及城市基础设施领域，具体是一种防盗井盖。
背景技术
在城市市政设施中，地下的输送管道、管线都留有井口以方便维修，井口处设有井座和井盖密封，但目前铁质的井盖往往容易被偷盗，而像塑料材质的则是经不起路上车的碾压而遭到破坏，给行人和车辆带来安全隐患。虽然在现有的井盖中有的设置了锁紧的装
置，但结构较为复杂，打开和关闭都较为麻烦。
发明内容
本发明所要解决的技术问题是 ：提供一种结构简单，打开和关闭方便快捷的防盗井盖。
本发明所采用的技术方案是 ：提供一种防盗井盖，包括井座和与井座配合的井盖本体，还包括能开启和关闭磁力的磁棒 ；所述的井盖本体设有竖向通孔和横向通孔，所述的竖向通孔设于井盖本体的中部，横向通孔设于井座和竖向通孔之间 ；所述的井座上设有和横向通孔相对应的井座孔，井座孔内设有磁性小于所述磁棒磁性的磁块，所述的横向通孔内设有锁紧销轴，所述的锁紧销轴滑动在横向通孔和井座孔内。
采用以上结构后，本发明防盗井盖能够通过磁棒插入竖向通孔内，将锁紧销轴滑出井座孔，解除井盖的锁紧状态，当磁棒的磁性消除时，在磁块的吸力作用下，重新滑到井座孔内，达到锁紧的目的，本发明结构设置简单，打开和关闭方便快捷。
作为优选，所述的横向通孔设为两个，对称设在竖向通孔的两侧，设置两个横向通孔，能够加强井盖的锁紧紧固性。
附图说明
图 1 为本发明防盗井盖的结构示意图。
图中，1、井座，2、井盖本体，3、磁棒，4、井座孔，5、横向通孔，6、锁紧销轴，7、磁块。
具体实施方式
以下结合附图和实施例对本发明做详细的说明。
如图 1 所示，本发明防盗井盖，包括井座 1 和与井座 1 配合的井盖本体 2，还包括能开启和关闭磁力的磁棒 3，井盖本体 2设有竖向通孔和横向通孔 5，竖向通孔设于井盖本体 2的中部，贯穿井盖本体 2 的厚度，横向通孔 5 设于井座 1 和竖向通孔之间，即横向通孔 5 一端和竖向通孔连通，井座 1 上设有和横向通孔 5 相对应的井座孔 4，也就是横向通孔 5 的另一端和井座孔 4 连通，井座孔 4 内设有磁性小于磁棒 3 磁性的磁块 7，横向通孔 5 内设有锁紧销轴 6，锁紧销轴 6 滑动在横向通孔 5 和井座孔 4 内。
本发明在具体实施时，横向通孔 5 设为两个，对称设在竖向通孔的两侧，也可以设为两个以上，可以将井盖本体 2 用链条连接在井座 1 上，防止维修时丢失。
本发明在使用时，将磁棒 3 插入竖向通孔内，开启其磁性，由于磁性大于设在井座孔 4 内的磁块 7 的磁性，磁棒 3 将锁紧销轴 6 吸住，井盖本体 2 得到解锁，当关闭磁棒 3 的磁性时，锁紧销轴 6 在磁块 7 的吸力作用下被吸回，井盖本体 2 被锁住，本发明防盗效果好，安全性较高，结构简单，打开和关闭方便快捷。
