Abstract

一种古力井口盖防盗机构,包括在盖体边沿处有竖向的螺栓,螺栓穿过盖体下端有横向的锁块,其特点是在螺栓内侧的盖体上留有锥形通孔,锁块的内端上留有与锥形通孔轴线重合的锁块小孔,锥形通孔内装有锥销,锥销的下端置于锁块小孔内。它解决了地下管道古力井的金属口盖,靠简单的螺栓、锁块锁定,盖体不安全的问题,广泛适应于污水管等各种地下管道检查井配装使用。

Description

古力井口盖防盗机构
技术领域
本实用新型涉及排污管道等检查维修设施领域,具体地说是一种污水管等地下管道检查井口盖保护装置。     
背景技术
    目前地下管道古力井的金属制口盖,大多是在盖体侧边留有螺栓孔,在将盖体安装到外座上后,再在螺栓孔内装上螺栓,靠螺栓下端的锁块卡住外座围沿,锁紧螺栓便可锁定盖体,这种结构简单,但很不安全,只要用专用扳手就可轻易取下盖体。 
实用新型内容
本实用新型为解决地下管道古力井的金属口盖,靠简单的螺栓、锁块锁定盖体不安全的问题,提供一种加装锥销的古力井口盖防盗机构。 
本实用新型的技术方案是,一种古力井口盖防盗机构,包括在盖体边沿处有竖向的螺栓,螺栓穿过盖体下端有横向的锁块,其特殊之处是,在螺栓内侧的盖体上留有锥形通孔,锁块的内端上留有与锥形通孔轴线重合的锁块小孔,锥形通孔内装有锥销,锥销的下端置于锁块小孔内。 
使用时,先将盖体装到外座围沿上,使锁块的外端卡到外座围沿的下面,锁紧螺栓,再将锥销装入锥形通孔,使锥销的下端沉入锁块小孔内即可。 
本实用新型的技术效果是,采用上述技术方案,可以实现一种安全可靠的古力井口盖防盗装置。它通过防盗锥销下端沉入锁块小孔阻止锁块转动,使锁块外端不脱离外座围沿,起到防盗作用。而要取出锥销则需要一种专用工具,这种针对性极强的专用工具不易仿造。 
附图说明
图1是本实用新型的结构主视图,并作摘要附图。 
在图中,1外座围沿、2螺栓、3锥形通孔、4盖体、5锁块、6锁块小孔、7锥销。 
具体实施方式
下面结合附图实例,对本实用新型进一步说明。 
如图所示,在盖体4边沿处装有竖向的螺栓2,螺栓2穿过盖体4下段上装有横向的锁块5;螺栓2内侧的盖体4上留有锥形通孔3,锁块5的内端上留有与锥形通孔3轴线重合的锁块小孔6,锥形通孔3内装有锥销7,锥销7的下端置于锁块小孔6内。 
使用时,先将盖体4装到外座围沿1上,使锁块5的外端卡到外座围沿1的下面锁紧螺栓2,再将锥销7装入锥形通孔3,使锥销3的下端沉入锁块小孔6内即可。
