Description

一种防盗人孔盖
本实用新型涉及一种人孔盖,具体的说,是一种防盗铸铁人孔盖。
随着城市建设的不断发展,人孔盖的用量越来越大,电缆道、自来水管道、大型广场的电器管道上面都有大量的人孔盖,目前,人孔盖许多没有防盗措施,时常有不法分子偷走人孔盖,给行人带来交通隐患,或者防盗结构复杂,制作成本较大,不易于推广使用。
本实用新型的目的在于提供一种防盗效果好、结构简单实用、制作成本低的铸铁人孔盖。
本实用新型是这样实现的:一种防盗人孔盖,包括人孔座、人孔盖,人孔盖与人孔座连接在一起,该人孔盖上铸造有通孔,通孔中安装弹簧销,弹簧销中部为弹簧,两边连接销轴,人孔座上铸造有一对盲孔,压紧弹簧销可以使人孔盖安装在人孔座上,并使销轴对应弹入盲孔中。
本实用新型的优点在于:弹簧销轴装入后,便不能够拆卸,防盗效果好,防盗结构简单,附加成本低,只需增加一根弹簧和两个销轴。
以下结合附图对本实用新型作进一步详细的描述:
图1为本实用新型局剖图。
图2为图1的A-A剖视图。
如图所示,弹簧销置于人孔盖2的通孔3中,弹簧销中部为弹簧5,两端为销轴6,两端的销轴6分别卡在人孔座1的一对盲孔4中,通孔3和盲孔4在铸造人孔盖2和人孔座1时同时铸出。
本实用新型的使用如下:将弹簧销放入人孔盖2的通孔3中,用一专用工具夹紧两销轴6的端面,放入人孔座1中,待两销轴6与人孔座1的两盲孔4同轴时,松开工具,在弹簧5的作用下,两销轴6弹入人孔座1的盲孔4中。人孔盖2以两销轴6为转轴,可自由抬起、落下,维修管道时很方便。
